    <dc:creator>jtyost2</dc:creator><description><![CDATA[There are, of course, considerable caveats to consider here. For one, Bridenstine said the SLS rocket, with its larger throw capacity, is still the agency's preferred option. But that rocket's first launch has been delayed until at least late 2020, and there is no guarantee it will be ready to fly by then.

There is also the matter of Gerstenmaier, who was seated in the front row of Monday's town hall. On multiple occasions, Bridenstine referred to the influential US spaceflight leader along the lines of, "Gerst is going to be so mad at me for saying all of this." Sources have told Ars that Gerstenmaier has, in fact, not yet bought into any of this.

Finally, there is politics. It is not clear whether Democrats would support a policy like this put forth by the Trump administration, although in the past they have been somewhat more favorable to private space companies such as SpaceX. Certainly there will be opposition from key Republican senators, such as Alabama's Richard Shelby, who will oppose any effort to sideline the SLS rocket.

For all of that, however, Bridenstine reiterated Pence's line that the "ends" of reaching the Moon matter far more than the "means." And he encouraged the NASA workforce to embrace the possibility of change that would accelerate what has, until now, been a rather slow pace in human spaceflight. "This is a big charge, and it comes straight from the top," Bridenstine said. "It's a once-in-a-lifetime opportunity."]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[The first American woman in space, Sally Ride, had to explain that women didn’t need 100 tampons for a one-week mission. The agency also designed a makeup kit for the female astronauts, which Ride laughed at. But her colleague, Rhea Seddon, requested it because she knew how the media represented women who appeared without makeup.

NASA has been aware of the problem with the EMUs for decades but lacks the funding to create new ones. All they can do is try to keep 40-year-old suits going, carrying a decades-long imprint of sexism into the present. Why are we asked to adapt our own spacesuits just to participate in space exploration? What kind of expectations are we carrying into the future when we have to figure out how to conform to decidedly earthbound expectations of beauty?

I was talking to my friend Kari Love, a retired spacesuit designer, who said that “while we can look back and understand why women were an afterthought in aerospace to this point, we are at serious risk for that to be reproduced as we move into the commercial spaceflight era.”

The decision to restaff the spacewalk by having astronaut Nick Hague join Koch was absolutely correct. The astronauts need to be safe. Having an all-female spacewalk was an accident. It wasn’t a priority. We have never been the priority. In the future of NASA and commercial spaceflight, it’s time to shift our priorities to include everyone.]]></description>

    <title>NASA’s Hubble spotted an asteroid spinning so fast it’s self-destructing</title>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[As NASA explains in a new blog post, the asteroid is a relatively large asteroid measuring roughly 2.5 miles across. It’s far from Earth, sitting some 214 million miles from the Sun, and it’s gradually coming apart as it spins. The asteroid completes a full rotation approximately every two hours, which is fast enough to cause it to fling its own material off into space.

It’s definitely a cool sight, but the fact that the asteroid is slowly eroding is actually a boon for scientists who study such space rocks. As it sheds its material, researchers can study the trails it leaves behind to learn more about the makeup of the rock itself.

“We didn’t have to go to Gault,” Olivier Hainaut of the European Southern Observatory in Germany said in a statement. “We just had to look at the image of the streamers, and we can see all of the dust grains well-sorted by size. All the large grains (about the size of sand particles) are close to the object and the smallest grains (about the size of flour grains) are the farthest away because they are being pushed fastest by pressure from sunlight.”

As for why the rock is spinning, scientists think they have a pretty good idea. It’s a phenomenon known as the YORP effect, and it’s all thanks to the Sun. When sunlight strikes the asteroid and heats its surface it radiates some of that energy back into space, causing the asteroid to turn slightly. As the rock turns, the Sun’s rays continue to heat it Sun-facing side, giving it more rotational momentum and eventually resulting in a rapidly spinning asteroid.]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[Vice President Pence on Tuesday called for American astronauts to return to the lunar surface within five years, a bold and exceedingly difficult challenge that would push NASA to its limits.

In a fiery speech in Huntsville, Ala., Pence repeatedly said the space agency needs to act with a renewed sense of urgency to land humans on the moon for the first time since 1972. And he cast the mission as part of a new space race against superpowers such as Russia and China, which landed a spacecraft on the far side of the moon earlier this year.

But most of all, Pence said NASA and its major programs have been stifled by a crippling bureaucracy that prevented the agency from moving more boldly in human exploration.

“It's not just competition against our adversaries,” Pence said. “We're also racing against our worst enemy: complacency.”

Pence did not provide details on how the agency would achieve landing humans on the moon in the five-year time frame, a monumental goal NASA had been hoping to achieve by 2028. He provided no details on the cost or how the mission would unfold. He added that he had learned the details of NASA’s plans only five minutes before stepping onstage.

NASA did not immediately respond to a request for more details about the plan or how it would be funded.]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[The Trump administration has announced it plans to put Americans on the moon no later than 2024—four years earlier than NASA had originally planned.

“Make no mistake about it, we're in a space race today, just as we were in the 1960s—and the stakes are even higher,” Vice Pres. Mike Pence said at a meeting of the National Space Council in Alabama on Tuesday.

Pence mentioned China's Chang'e 4 mission, which landed a robotic probe on the far side of the moon in January. The mission “revealed [China's] ambition to seize the lunar strategic high ground and become the world’s pre-eminent spacefaring nation,” Pence said.

At least one expert disagrees that such a space race exists. “If the United States is racing to return to the moon, it is racing against itself, not China,” Gregory Kulacki, a space analyst with the Union of Concerned Scientists in Massachusetts, told The Daily Beast.]]></description>

    <title>India Shot Down a Satellite, Modi Says, Shifting Balance of Power in Asia</title>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[Prime Minister Narendra Modi of India announced on Wednesday that India had shot down a satellite in a ballistic missile test, escalating the country’s rivalry with China and Pakistan, and demonstrating a strategic strength that few countries can claim.

If confirmed, a successful missile test could destabilize the balance of power between India and Pakistan, both nuclear powers that for years have eyed each other warily, with hostilities briefly breaking out last month.

This technological leap puts India in the exclusive club of nations, along with the United States, Russia and China, that have proved their ability to destroy targets in space. This could be a crucial advantage in war, allowing a country essentially to blind another by taking out the enemy’s space-based communication and surveillance satellites.]]></description>

    <title>American Astronauts to Return to Moon Within 5 Years, Pence Pledges</title>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[American astronauts will walk on the moon again in the next five years, Vice President Mike Pence declared on Tuesday at a meeting of the National Space Council.

“It is the stated policy of this administration and the United States of America to return astronauts to the moon within the next five years,” Mr. Pence said at the U.S. Space and Rocket Center in Huntsville, Ala., on a stage that contained a model of one of the Apollo landing modules that first transported American astronauts to the lunar surface 50 years ago.

Mr. Pence described a need for NASA to take on greater urgency in returning to the moon. At the same time, the goal of accelerating that pace has not been reflected in the administration’s NASA budget requests to Congress.

The vice president’s remarks reflected frustration within the Trump administration at repeated delays in the development of NASA’s giant rocket, the Space Launch System, and Orion, a capsule for taking astronauts beyond low-Earth orbit to the moon and possibly, eventually, to Mars.

NASA’s current schedule sets 2023 for the first flight of Orion with astronauts aboard. A moon landing would not occur until 2028, almost a decade from now.

Critics, including Mr. Pence, say that pace is too slow, pointing out that in the 1960s, only eight years elapsed between President John F. Kennedy’s pronouncement in 1961 of a goal of reaching the moon and the landing of Apollo 11 in 1969.

“Ladies and gentleman, that is just not good enough,” Mr. Pence said. “We are better than that.”

Mr. Pence raised the specter of China, which is also looking to land astronauts on the moon in the 2020s, as well as the cost of relying on Russia, which has provided transportation for NASA astronauts to the International Space Station since the retirement of the space shuttles in 2011.

“We're also racing against our worst enemy,” Mr. Pence said. “Complacency.”]]></description>

The level of detail packed into Ryan Olsen‘s small model is impressive — the grille bricks providing texture on the sides, the machinery on the roof, and the massive shutter doors. Don’t miss the Saturn V rocket on its way to the launch-pad atop the crawler-transporter, or the perfect shaping of the Launch Control Centre with its sloped windows, jutting at an angle away from the main structure. The only thing I’d challenge on this model is using 1×1 plates for cars — unfortunately they don’t quite fit the scale. The rest of it is bang-on though, making me want to head back to Florida and get a refresher boost to my space-geekery.]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[Bees buzzing, flowers blooming and birds singing are some telltale signs that spring is upon us. But do you ever wonder what the season looks like from space?

This image from the Meteosat-9 satellite shows Earth on the vernal equinox, the official start of spring in the Northern Hemisphere. This year, that day fell on Wednesday, March 20, as it did in this photograph taken in 2011.

The spring equinox is a point in Earth’s orbit where the sun shines directly above the Equator, creating nearly equal periods of daytime and nighttime across the globe.

“Only on the equinoxes do we get that exactly straight terminator,” said Greg Redfern, a solar system ambassador at NASA’s Jet Propulsion Laboratory, referring to the line separating daylight from the darkness of night.

That line is continually shifting because Earth is tilted 23.5 degrees on its axis. “If the Earth didn’t have that tilt, we’d always have the straight-up-and-down terminator and we wouldn’t have seasons,” Mr. Redfern said.]]></description>

In a simulation, material smashed away from an asteroid following a collision is attracted back to the object by its gravity.CreditBy Charles El Mir/johns Hopkins University

Faced with the prospect of a sizable asteroid heading toward Earth and causing doomsday, humanity has come up with various responses.

Hollywood may reckon that the best way to destroy an errant space rock is with nuclear weapons. This is rarely the preferred option of experts, but using some sort of spacecraft system to smash an asteroid into small, harmless pieces is seen as a real-world possibility. A new study, looking at a gigantic space rock-on-space rock clash, hints at how utterly ineffective this type of asteroid assassination attempt may be.

Using computer models, scientists simulated a 4,000-foot asteroid smashing into a 15.5-mile asteroid at 11,200 miles per hour. Immediately after colliding, the large asteroid cracked considerably, with debris flowing outward like a cascade of Ping-Pong balls. Despite some deep fractures, the heart of the asteroid was not comprehensively damaged.]]></description>

Philae, the first spacecraft to land on a comet, was dropped on to the surface of Comet 67P by its mothership, Rosetta, last November.
It worked for 60 hours before its solar-powered battery ran flat.
The comet has since moved nearer to the Sun and Philae has enough power to work again, says the BBC's science correspondent Jonathan Amos.
An account linked to the probe tweeted the message, "Hello Earth! Can you hear me?"
On its blog, Esa said Philae had contacted Earth, via Rosetta, for 85 seconds on Saturday in the first contact since going into hibernation in November.]]></description>

After sending the Mars Curiosity rover to the red planet, Nasa are now planning the Mars 2020 mission, in which they intend to include a device which can slowly convert the atmosphere on Mars into breathable oxygen (and no, it’s not just a tree).

The MOXIE, as the boffins call it, was designed by MIT and will initially be used to create an unlimited supply of breathable air for for first astronauts to settle on Mars.

However the concept of ‘terraforming’ – the process of transforming a planet’s environment to make it hospitable for humans – which was once a staple of science fiction stories could now theoretically be achieved.

The MOXIE device could even generate liquid oxygen on Mars, potentially providing fuel for the astronauts to undertake a return journey to earth.]]></description>

    <title>Ancient Mars Had an Ocean, Scientists Say</title>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[After six years of planetary observations, scientists at NASA say they have found convincing new evidence that ancient Mars had an ocean.

It was probably the size of the Arctic Ocean, larger than previously estimated, the researchers reported on Thursday. The body of water spread across the low-lying plain of the planet’s northern hemisphere for millions of years, they said.

If confirmed, the findings would add significantly to scientists’ understanding of the planet’s history and lend new weight to the view that ancient Mars had everything needed for life to emerge.

“The existence of a northern ocean has been debated for decades, but this is the first time we have such a strong collection of data from around the globe,” said Michael Mumma, principal investigator at NASA’s Goddard Center for Astrobiology and an author of the report, published in the journal Science. “Our results tell us there had to be a northern ocean.”

But other experts said the question was hardly resolved. The ocean remains “a hypothesis,” said Ashwin Vasavada, project scientist of the Curiosity rover mission at the Jet Propulsion Laboratory in Pasadena, Calif.

Dr. Mumma and Geronimo Villanueva, a planetary scientist at NASA, measured two slightly different forms of water in Mars’ atmosphere. One is the familiar H2O, which consists of two hydrogen atoms and one oxygen atom.

The other is a slightly “heavier” version of water, HDO, in which the nucleus of one hydrogen atom contains a neutron. The atom is called deuterium.

The two forms exist in predictable ratios on Earth, and both have been found in meteorites from Mars. A high level of heavier water today would indicate that there was once a lot more of the “lighter” water, somehow lost as the planet changed.

The scientists found eight times as much deuterium in the Martian atmosphere than is found in water on Earth. Dr. Villanueva said the findings “provide a solid estimate of how much water Mars once had by determining how much water was lost to space.”]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[Of course, that doesn’t mean that the story is over. There is a clearer answer, which is to have SpaceX declare that it will put the images from its spacecraft into the public domain as well. After all, this is the same Elon Musk who recognizes that patents often hold back innovation, and has thus agreed to free up all of Tesla’s (and who has also admitted that SpaceX didn’t spend much effort on patents). So he already recognizes that perhaps overprotecting via intellectual property is a bad idea. 

So, now he can do the same thing with respect to those photos. While it’s not a perfect solution, Musk can (and should) make use of something like the CC0 public domain declaration offered by Creative Commons to make it clear that these photos should be treated the same way that NASA’s images are: as public domain materials for everyone to use.]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[The deadline for Google’s Lunar XPRIZE has been delayed by a year to December 31st, 2016, the company announced in a press release today. The news comes in the wake of a tough year for private spaceflight, during which multiple rocket failures and a fatal crash involving Virgin Galactic’s SpaceShip Two served as harsh reminders of the difficulty of space travel. At least one team must submit documentation for a scheduled launch by December 31st, 2015 for the competition to be extended.

“We know the mission we are asking teams to accomplish is extremely difficult and unprecedented, not only from a technological standpoint, but also in terms of the financial considerations,” XPRIZE president Robert Weiss said in the release. “It is for this reason that we have decided to extend the competition timeline.”

To win the $20 million grand prize, the winning team must be the first to land a spacecraft on the Moon — but that’s not all. They must also drive it 500 meters on, above, or below the lunar surface, and transmit HDTV “Mooncasts” back to Earth. The competing teams, which are from all over the world, must accomplish this with no more than 10 percent in government funding.]]></description>

The ship is designed eventually to take humans beyond the space station, to destinations such as the Moon and Mars.

Orion's brief flight today will be used to test critical technologies, like its heat shield and parachutes.

The Delta IV-Heavy rocket roared off the pad at Cape Canaveral at 07:05 local time (12:05 GMT).

It will throw the conical ship to 6,000km above the planet, to set up a fast re-entry into the Earth's atmosphere.

This will generate temperatures in the region of 2,000C, allowing engineers to check that Orion's thermal protection systems meet their specifications.

The mission teams will also get to watch how the parachutes deploy as they gently lower the capsule into Pacific waters off the coast of Mexico's Baja Peninsula.

That splashdown is expected to occur at about 11:30 EST (16:30 GMT).

Nasa has a drone in the area hoping to relay video of the final moments of descent.]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[After a historic but awkward comet landing, the robot probe Philae is now stable and sending pictures - but there are concerns about its battery life.

The lander bounced twice, initially about 1km back out into space, before settling in the shadow of a cliff, 1km from its intended target site.

It may now be problematic to get enough sunlight to charge its battery systems.

Launched in 2004, the European Space Agency (Esa) mission hopes to learn about the origins of our Solar System.

It has already sent back the first images ever taken from the crumbling, fractured terrain of a comet.

Philae got to the icy 67P/Churyumov-Gerasimenko on the back of Esa's Rosetta satellite after a 10-year, 6.4 billion-km (4bn-mile) journey, which reached its climax on Wednesday with a seven-hour drop to the surface.

After showing an image that indicates Philae's presumed location - on the far side of a large crater that was earlier considered but then rejected as a landing site - the head of the lander team, Stephan Ulamec, said: "We could be somewhere in the rim of this crater, which could explain this bizarre… orientation that you have seen."]]></description>

The jump was made by Alan Eustace, 57, a senior vice president at Google. At dawn he was lifted by a balloon filled with 35,000 cubic feet of helium, from an abandoned runway at the airport here.

For a little over two hours, the balloon ascended at speeds up to 1,600 feet per minute to an altitude of 135,908 feet. Mr. Eustace dangled underneath in a specially designed spacesuit with an elaborate life-support system. He returned to earth just 15 minutes after starting his fall. .

“It was amazing,” he said. “It was beautiful. You could see the darkness of space and you could see the layers of atmosphere, which I had never seen before.”

Mr. Eustace cut himself loose from the balloon with the aid of a small explosive device and plummeted toward the earth at speeds that peaked at more than 800 miles per hour, setting off a small sonic boom heard by observers on the ground.]]></description>

A bill now in front of the US Congress would help by allowing them to own what they discover - but it might, if passed, meet stiff international opposition.

Chris Lewicki is trying to get water from a stone. A really big stone thousands of miles from Earth.

The president of space mining firm Planetary Resources used to oversee robotic Mars missions at Nasa, but today he’s betting big on asteroids.

The chunks of matter hurtling through the cosmos are rich in valuable minerals, he says, but finding water could be like striking liquid gold.

“We can tell from telescopes that look out from mountaintops here on Earth that certain types of asteroids can be relatively abundant in water and water-bearing minerals,” he says.

But why is water, which covers much of our planet, so valuable in space?

According to Lewicki, it currently costs nearly $2bn (£1.2bn) per year to launch enough water - six tons per person - to sustain the six astronauts aboard the International Space Station.

    <dc:creator>jtyost2</dc:creator><description><![CDATA[Keeping the costs of space exploration as low as possible is especially important for a country like India — critics point out that the country might be better served spending that money on public health or poverty reduction, as a fifth of its population still lives below the poverty line.

But the Indian Space Research Organization (ISRO) minimized expenses in a number of ways. It was able to use relatively small rockets because the scientific payload is extremely light (about 33 pounds, compared to MAVEN’s 143 pounds), and relied heavily on proven, established launch technologies it’s previously used to launch satellites.

Additionally, the entire mission was carried out in an extremely short time — about a year from approval to launch. Perhaps most importantly, salaries of engineers and other specialists are simply lower in India — the ISRO’s total budget is $1.2 billion per year, compared to $17.5 billion for NASA.]]></description>

MAVEN spent just over 10 months plying the vacuum of interplanetary space after its launch in November of 2013. As it approached Mars, it fired its engines for a total of just over a half hour, changing velocity enough to transfer from a heliocentric orbit into one about Mars. The scale of such an accomplishment is hard to overstate; it’s an incredible achievement, and one we’ve done over and again.]]></description>

The US space agency Nasa has picked the companies it hopes can take the country’s astronauts back into space.

It is awarding up $6.2bn to the Boeing and SpaceX firms, to help them finish the development of new crew capsules.

Since the space shuttles were retired in 2011, the Americans have relied on Russia and its Soyuz vehicles to get to the International Space Station.

Boeing and SpaceX should have their seven-person crew ships ready to take over the role by late 2017.

Disagreements over Moscow’s actions in Ukraine have made the current Soyuz arrangement increasingly unpalatable for Washington.

So has the price per flight now being charged - at $70m (£43m) per US astronaut seat. American officials regard this as excessive.

The Obama administration charged Nasa in 2010 with the job of “seeding” indigenous, competing companies to restore American capability.]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[Today, with the selection of Boeing and SpaceX to be the first American companies to launch our astronauts to the International Space Station, NASA has set the stage for what promises to be the most ambitious and exciting chapter in the history of human space flight.

From day one, the Obama Administration has made it clear that the greatest nation on Earth should not be dependent on other nations to get into space. Thanks to the leadership of President Obama and the hard work of our NASA and industry teams, today we are one step closer to launching our astronauts from U.S. soil on American spacecraft and ending the nation’s sole reliance on Russia by 2017. Turning over low-Earth orbit transportation to private industry also will allow NASA to focus on an even more ambitious mission – sending humans to Mars.

We have already fulfilled part of the President’s vision. For the past two years, two companies, SpaceX and Orbital Sciences, have been making regular cargo deliveries to the International Space Station. The contracts we are announcing today are designed to complete the NASA certification for human space transportation systems capable of carrying people into orbit. Once certification is complete, NASA plans to use these systems to ferry astronauts to the International Space Station and return them safely to Earth. Again, this will fulfill the commitment President Obama made to return human spaceflight launches to U.S. soil and end our sole reliance on the Russians.]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[If both these missions happen, they’d be able to spot the vast majority of mid-sized asteroids that could pose a threat. But the NASA mission is still just a proposal — one that is reportedly short on money — and the B612 mission is also short of its fundraising goal.

Further, if we did spot an asteroid heading our way, we don’t have any proven means of stopping it. The simplest way would probably be sending a craft crashing into the asteroid, nudging it off its path enough so that it’d miss Earth. The UN has proposed designing and testing a network of small probes that would be capable of doing so, but it’s still waiting on the necessary funding from various national space agencies, with an estimated price tag of about $2.5 billion.

Funding all three of these projects — the two telescopes and the impact avoidance system — would cost a lot. Let’s be generous and say they’d cost $5 billion in total. Now compare that to the cost of, say, the cost of the Sochi Olympics ($51 billion), or the cost of the F-35 fighter plane program ($400 billion). Screw it, compare it to the cost of a new football stadium for the Dallas Cowboys ($1.2 billion, with about a quarter paid by taxpayers).

When it comes to asteroids, we’re talking about natural disasters that are probably preventable. Figuring out how to do so would be a relatively cheap insurance plan that would benefit the entire species.]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[NASA has amassed more than 1.3 million pictures of Earth as seen from the International Space Station, and about a third of them were taken at night. The space agency says those photos are the highest-resolution nighttime pictures available from orbit, but their usefulness is limited because it's not always clear exactly what the pictures are showing.

That's where you can help.

The Complutense University of Madrid is heading up a crowdsourcing project called Cities at Night to catalog the space station's nighttime imagery. The easiest part of the project, called Dark Skies ISS, asks Internet users merely to sort the images into pictures of cities, stars and other objects. Another online effort, Night Cities ISS, draws upon participants' knowledge of local geography to match bright points of light to locations on a map.

The most complicated challenge, Lost at Night, calls upon citizen scientists to identify cities in wide-angle nighttime pictures. "We don’t know which direction the astronaut pointed the camera, only where the station was at the time the image was taken," Alejandro Sanchez, a student at Complutense University, said in a NASA feature about the project. "Some images are bright cities but others are small towns. It is like a puzzle with 300,000 pieces."

The project could open up new fields of research. Nighttime satellite readings already have been used to chart the rise and fall of political leaders — and there are few better illustrations of the economic disparity between North and South Korea than the space station's picture of the peninsula's dark patch. Pinpointing the locations in NASA's nighttime pictures could help scientists track energy efficiency as well as the health and environmental effects of light pollution.]]></description>

Clay-bearing sedimentary rocks on the crater floor in an area called Yellowknife Bay yielded evidence of a lakebed environment billions of years ago that offered fresh water, all of the key elemental ingredients for life, and a chemical source of energy for microbes, if any existed there.
"Before landing, we expected that we would need to drive much farther before answering that habitability question," said Curiosity Project Scientist John Grotzinger of the California Institute of Technology, Pasadena. "We were able to take advantage of landing very close to an ancient streambed and lake. Now we want to learn more about how environmental conditions on Mars evolved, and we know where to go to do that."]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[ALTHOUGH widely used, satellites are expensive to build and to launch. That began to change last year. On November 19th Orbital Sciences, an American company, launched a rocket from the Wallops Flight Facility in Virginia. It carried 29 satellites aloft and released them into low-Earth orbit, a record for a single mission. Thirty hours later, Kosmotras, a Russian joint-venture, carried 32 satellites into a similar orbit. Then, in January 2014, Orbital Sciences carried 33 satellites up to the International Space Station (ISS), where they were cast off a month later.

Many of these 94 satellites were built in a standard format known as a CubeSat, a 10cm (4 inch) cube weighing 1.3kg (2.9lb) or less. Some comprised units of two or three cubes. After a decade of fits and starts, during which some 75 CubeSats were launched, satellites of this scale and other small satellites are moving from being experimental kit to delivering useful scientific data and commercial services.

In the next five years or so some 1,000 nanosats, as small satellites of 1-10kg are called, are expected to be launched. Some will be smaller than a CubeSat; others bigger and heavier. Some are like a matryoshka doll: the Russian launch included a satellite that launched eight smaller ones, including four PocketQubes (a 5cm cube format). One of these smaller satellites, developed in Peru, released its own tiny bird.]]></description>

    <title>Virgin Galactic Gets FAA Approval, Hopes to Start Space Tourism by End of 2014</title>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[Virgin Galactic has signed a deal with the FAA that will formally allow them to charter space flights from their New Mexico base. It also specifies rules for how those flights will integrated into United States airspace (the place where non-space planes usually fly.) The deal is a major step for commercial space travel and puts Virgin Galactic on track to start offering flights by the end of 2014.

The Wire spoke with Virgin Galactic spokesperson Jessica Ballard, via email, to learn a bit more about space tourism. Ballard told us that the first trip out of “Spaceport America” in New Mexico will be reserved for Sir Richard Branson and his family. After that, flights will be available to the masses. Well, the masses who can afford a ride. The tickets are $250,000 per person, but if you want to charter the entire plane for a large group there might be a small discount. 

Once you’ve ponied up the $250,000, you get to experience three days of preparation at Spaceport America before you can go up. The preparation includes “team-bonding and training onsite.” Space tourists will be “learning how to make the most of the time in microgravity and tips on how to be comfortable and safe in macro gravity will form an important part of the preparation, as well as to be thoroughly familiar with all safety and emergency procedures.”

The actual flight is about two hours long. The SpaceShipTwo “will hitch a one hour ride up to a launch altitude of 46,000 to 47,000 feet attached to WhiteKnightTwo, the specially-designed carrier aircraft or mothership. When the launch altitude is reached, the spaceship is released and ignites its hybrid rocket motor.” Then, the fun part begins: the spaceship accelerates within eight seconds to supersonic speeds, eventually reaching Mach 3.5. Then, there are a few minutes of weightlessness (that’s what you paid the $250k for after all.) The flight takes you up to a maximum altitude of 68 miles. 

So, now that the FAA has signed off, Virgin can officially and legally take you to space come December.  ]]></description>

Of course, that was just the beginning for SpaceX — Musk is nothing if not ambitious — and the company's next goal is to tackle manned space flight.

Last night at its Hawthorne, California headquarters, SpaceX unveiled its newest capsule, the Dragon V2. Designed as a reusable craft for up to seven astronauts, the V2 differs from its predecessor not just in terms of what it carries but how it gets back home; according to Musk, the new craft disposes with the concept of ocean splashdowns altogether, and "can land anywhere on Earth with the accuracy of a helicopter." With a touchscreen control system, 3D printed engines, and a slick, minimalist interior, the V2 feels so close to science fiction it's hard to believe it exists — but we were there last night and took a step inside.]]></description>

We have no answer to the Fermi Paradox—the best we can do is “possible explanations.” And if you ask ten different scientists what their hunch is about the correct one, you’ll get ten different answers. You know when you hear about humans of the past debating whether the Earth was round or if the sun revolved around the Earth or thinking that lightning happened because of Zeus, and they seem so primitive and in the dark? That’s about where we are with this topic.

In taking a look at some of the most-discussed possible explanations for the Fermi Paradox, let’s divide them into two broad categories—those explanations which assume that there’s no sign of Type II and Type III Civilizations because there are none of them out there, and those which assume they’re out there and we’re not seeing or hearing anything for other reasons:]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[If these tensions don’t resolve by 2020, things could really get messy in space. Private American space companies are hoping to have their own transport systems in place by then — so NASA could theoretically access the station on its own — but Russia is claiming that its space agency, Roscosmos, would try to operate its portion of the station without NASA involvement.

“The Russian segment can exist independently from the American one. The US one cannot,”Russian deputy prime minister Dmitry Rogozin said during the announcement.

That’s probably not true: the majority of the station’s power, among other capabilities, comes from solar panels on the American segment. Without both countries’ involvement, it seems unlikely that the station — the only occupied outpost our species has in space — can survive. And either way, it’s clear that the two countries’ space relationship, once a triumph of the post-Cold War era, is quickly going down the pipes.]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[Most people associate Nasa with rocket science but now the American space agency has turned its attention to rocket salad. A portable greenhouse to grow lettuces was taken to the International Space Station (ISS) during last week's supply mission.

Provided that the astronauts can cut the mustard, they should be eating their first homegrown space salad before the end of the year. This will be the first time a Nasa astronaut has tasted something grown in orbit.

Until now, all supplies have been taken from Earth. But, according to Dr Gioia Massa, a payload specialist at the Kennedy Space Centre, Florida, there is no reason why this has to be the case. "If you can get the environmental conditions correct, there's no reason why plants won't grow pretty well in space," she says.

She was inspired to grow plants in space in the 1980s during an agriculture class when she was 13. Her school was within sight of the Kennedy Space Centre and she would watch space shuttle launches from the playground.

Now her deployable vegetable production system (Veggie for short) is on board the ISS and ready for business. It is a pop-up greenhouse that collapses to the size of a briefcase for stowage during launch.

The main obstacle to growing plants in space is the lack of gravity, since the soil tends to float away. Massa's solution has been to design the equivalent of something familiar to all tomato wranglers: a grow bag. The space agency calls these "plant pillows".

Three plant pillows have been taken up to the ISS and will be sown in succession. Two hold seeds for a variety of red romaine lettuce called Outredgeous. The third contains the flowering plant zinnia, to add a splash of colour to the space station.]]></description>

Scientists earlier believed that asteroids bigger than 20 meters — like the one that injured about 1,500 people in Chelyabinsk back in February 2013 — only collide with Earth every 150 years or so, on average.

scientists now believe 20-meter wide asteroids will hit our planet once every 25 years

But new findings have forced them to revise this view. The B612 Foundation, an organization devoted to detecting dangerous asteroids, has released data that indicate these sorts of asteroids could actually hit Earth once every 25 years, on average.

Using a global network of sensors originally built to detect nuclear weapons tests, asteroid researcher Peter Brown has determined that the Chelyabinsk meteorite was just the biggest of 26 measurable impacts that have happened worldwide since 2001. Most of these were smaller asteroids that burned up in the atmosphere or landed in unpopulated places, but this number is still way more — 3 to 10 times higher — than the previous models predicted.

So how much should you be worrying about the possibility of death by asteroid? Here’s an explanation of the risk they pose.]]></description>

Nasa's Robonaut 2 has the makings of the perfect space surgeon.

The humanoid has already been posted to the International Space Station, the only problem is its motor skills are somewhat rudimentary at the moment.

In truth, it can't even walk in zero gravity yet, and perhaps its most impressive physical feat to date has been to catch a floating roll of duct-tape.

But Nasa has high hopes for the new recruit, and techniques being developed by a team on the ground could mean the machine can eventually perform life-saving operations on its team-mates.

"The idea is for him to be the best medic, nurse, and physician," Dr Zsolt Garami of the Houston Methodist Hospital tells the BBC.

"Our plan is to use Robonaut as a telemedicine doctor in remote areas."

As Robonaut's name suggests, it is not alone. There are currently four versions of the android with more in development.]]></description>

Much of the information about the X-37B and its mission is classified, but the little that is public points to it being a development vehicle for new Air Force space capabilities while serving a secondary role for the U.S. military and intelligence community as a testbed for new space-based surveillance technologies.

The current mission, dubbed USA-240, is the third for the X-37B and began on Dec. 11, 2012, atop an Atlas V rocket at Cape Canaveral. The spacecraft is taken into orbit on a rocket but lands like the space shuttle by gliding down to Earth.

That isn't the only similarity it shares with the space shuttle. It looks visually similar, sort of like a mini shuttle, and it, too, started life as a NASA project. The space agency solicited proposals in 1998 for projects that would push the boundaries of space development and exploration, and later awarded Boeing a US$137 million contract for the X-37.

Originally envisioned as something that would be launched from the shuttle to test reusable launch vehicle technology, the X-37 never made it into space and eventually was transferred from NASA to the Defense Advanced Research Projects Agency (DARPA) in 2004.

That's when it moved into the shadows.

It didn't emerge again until April 22, 2010, when the Air Force launched an Atlas rocket carrying what had been renamed the X-37B. Details of the mission were kept secret, but soon after launch, amateur satellite hunters spotted the X-37B orbiting the Earth at about the same altitude as military satellites.]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[As my flight home roars down a runway at the Philadelphia airport, I find myself calculating my Gx (no more than two, I decide), and as we bank upward and then to the right, I can sense Gz creeping into the mix. I feel my blood being gently nudged toward my feet, although I know it’s not enough to take it away from my brain. 

Most important, I’m suddenly aware of the cocoon of technology that’s compensating for my body’s vulnerability to it all. Cabin pressurization is top of mind for me at the moment. Ten thousand feet, it turns out, isn’t just the altitude past which it’s okay to use portable electronic devices. It’s also the altitude at which passengers begin to require oxygen assistance. At our cruising altitude of 32,000 feet, no one on board could function for more than 15 seconds without the oxygen mix in our cabin. After that, we’d start to pass out and die. 

And yet I’m leaning back and turning on a movie, content that the systems around me will keep me alive. After all, millions of people have flown before me. 

Is that what it will take to establish confidence in private space travel? Millions of people going first? Hundreds of thousands? Thousands? It seems impossible, somehow, that the requisite number of volunteers are willing to risk nausea—or worse—to see the stars 62 miles closer than we can from the ground. Certainly, Wright and his group are undaunted, powered by a lifelong desire to experience space firsthand and aided by physical capabilities that I simply don’t have. I wish them the best. If successful, they’ll redefine what it means to have the right stuff—and hopefully pioneer a new citizen-space science in the process. But while their place may be in the stars, my place, I learned, is right here on Earth. ]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[I followed up with Leonard Garcia, who has been one of the leaders of the attempt to regain control of ISEE-3, to ask what, in fact, the cost was. He told me that when the Deep Space Network realized what was going to be involved in regaining this capability, they did not even proceed as far as developing a cost estimate; "they decided this wasn't going to be possible."

How could this happen? Well, the fact that ISEE-3 is still broadcasting a carrier signal was actually an error; it should have been shut down. If they had planned for it to still be functioning at this point, they would have maintained the capability to communicate with it. I don't comprehend the intricacies of deep-space communications well enough to understand the obstacles here, and I don't question their conclusion, but that doesn't make me any less sad.

So ISEE-3 will pass by us, ready to talk with us, but in the 30 years since it departed Earth we've lost the ability to speak its language. I wonder if ham radio operators will be able to pick up its carrier signal -- it's meaningless, I guess, but it feels like an honorable thing to do, a kind of salute to the venerable ship as it passes by.]]></description>

The one released by NASA, which was "processed to remove effects of cosmic rays," was taken about 80 minutes after Mars' sunset with what researchers call Curiosity's "left eye camera" on its "Mastcam." It show not just Earth but another dot that NASA says is our moon. (Earth was about 99 million miles away at that point, according to NASA's Jet Propulsion Laboratory. Curiosity traveled a much longer distance to get to Mars because both planets are constantly in motion.)
Any Martian or Earthling who happened to be visiting wouldn't need such a special camera to see the same thing.
According to NASA, "A human observer with normal vision, if standing on Mars, could easily see Earth and the moon as two distinct, bright 'evening stars.'"
Of course, photographing its native planet isn't Curiosity's main mission, which is exploring Mars.]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[It’s time to stop throwing pity parties for Pluto. The beloved not-quite-planet is about to become the star of our solar system. I’ll go out on a limb and predict that in July 2015, the up-close photos of Pluto we’ll get from a NASA spacecraft will be the most popular astronomical images of a generation. Screensavers, posters, live TV, Twitpics, you name it—Pluto will be everywhere. After all, we’ve been wondering what it looks like for decades.

But even now—and this is what most people don’t realize about Pluto—we owe that little iceball a ton of respect. It led the way to a brand-new view of what our solar system is really made of. Here’s the answer in advance: Almost all of the worlds circling our sun are like Pluto. There are thousands of them. Pluto’s orbit, which used to seem weird, also showed us the violent history of how the big planets—the ones that get all the glory—got to where they are now. Its idiosyncrasies gave us the first, and best, clues about the history of our little nook of the Milky Way.

In other words, Pluto rules, regardless of what we humans deign to call it.]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[The Obama Administration is prepared to commit the money for its part of the International Space Station through 2024, according to internal documents obtained by the Orlando Sentinel. That would mean at least another four years in orbit for the ISS, provided future administrations follow through on the plan.

According to the Sentinel's report, the structure itself should be viable beyond 2028, but it costs several billions of dollars a year to operate—money that NASA could clearly put to other uses. Without the money, however, the station would need to be safely deorbited, and it's not something that could easily be replaced.

The ISS also has peripheral benefits. It keeps NASA engaged with international partners at a time when the agency is cutting back its involvement in projects like a planned robotic mission to Europa. Resupply missions have also allowed NASA to foster new commercial rocketry ventures. In the longer term, some of those will start ferrying astronauts to low-Earth orbit. The original 2020 time limit would allow the commercial ventures to do a few crewed missions, but the extra four years will provide significantly more experience.

The documents also indicate that the station is coming into its own as a laboratory. Five years ago, the ISS crew averaged only three hours a week dedicated to scientific work. Now, with the station complete and a lot of experience, that number has shot up to 50 (although there's continued debate about the value of the work performed in orbit).

More generally, the commitment allows NASA to do something it's struggled with in recent decades: plan long term. With each administration changing the agency's priorities and its budget always a question mark, NASA has cancelled or retooled countless programs. Now, it should have some idea of what its future holds—provided, of course, that Obama's successor stays with the program.]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[A Chinese spacecraft has landed on the moon in the first "soft landing" since 1976.

The event, broadcast live on Chinese TV, means the country has joined the US and the former Soviet Union in managing to accomplish such a feat.

The Chang'e 3, named after a lunar goddess in traditional Chinese mythology, is carrying the solar-powered Yutu, or Jade Rabbit rover, which will dig and conduct geological surveys. The mission is expected to last three months.

At 9:14 pm local time (1314 GMT), the official Xinhua news service reported that the spacecraft had touched down in the Sinus Iridum, or the Bay of Rainbows, at 9:12 p.m. after hovering over the surface for several minutes seeking an appropriate place to land.

A soft landing does not damage the craft and the equipment it carries. In 2007, China put another lunar probe in orbit around the moon, which then executed a controlled crash on to its surface.

The rover will be manipulated by Chinese control centres with support from a network of tracking and transmission stations operated by the European Space Agency.

In China's most recent manned space mission in June, three astronauts spent 15 days in orbit and docked with an experimental space laboratory, part of Beijing's quest to build a working space station by 2020.]]></description>

The coronal mass ejection, or CME, event was likely more powerful than the famous Carrington storm of 1859, when the sun blasted Earth’s atmosphere hard enough twice to light up the sky from the North Pole to Central America and allowed New Englanders to read their newspapers at night by aurora light, said CU-Boulder Professor Daniel Baker. Had it hit Earth, the July 2012 event likely would have created a technological disaster by short-circuiting satellites, power grids, ground communication equipment and even threatening the health of astronauts and aircraft crews, he said.

CMEs are part of solar storms and can send billions of tons of solar particles in the form of gas bubbles and magnetic fields off the sun’s surface and into space.  The storm events essentially peel Earth’s magnetic field like an onion, allowing energetic solar wind particles to stream down the field lines to hit the atmosphere over the poles.

Fortunately, the 2012 solar explosion occurred on the far side of the rotating sun just a week after that area was pointed toward Earth, said Baker, a solar scientist and the director of CU-Boulder’s Laboratory for Atmospheric and Space Physics. But NASA’s STEREO-A, satellite that was flying ahead of the Earth as the planet orbited the sun, captured the event, including the intensity of the solar wind, the interplanetary magnetic field and a rain of solar energetic particles into space.

“My space weather colleagues believe that until we have an event that slams Earth and causes complete mayhem, policymakers are not going to pay attention,” he said. “The message we are trying to convey is that we made direct measurements of the 2012 event and saw the full consequences without going through a direct hit on our planet.”]]></description>

    <dc:creator>jtyost2</dc:creator><description><![CDATA[The timeline for Mars One, the space exploration program intended to send humans on a one-way trip to Mars that has earned a fair share of dubious looks and sideways glances from the technology and science community, has been pushed back two years as of Tuesday. The company announced the new timeline as well as commissions for both Lockheed Martin and Surrey Satellite Technology Ltd. to develop “mission concept studies” for the expedition.
Lockheed Martin is at work on Mars One’s lander, which will be designed after NASA’s Phoenix mission lander, another Lockheed Martin project. The Phoenix spacecraft touched down in May 2008, completed all planned experiments by November 2008, and then lost contact with Earth.]]></description>
