<blockquote>SpaceX has dumped 250 pounds of trash on Saskatchewan. Things you don't want coming your way at terminal velocity include an 8 foot, 80 pound tall wall panel shaped like a spear.
It turns out that Canada is an entirely other country than Texas, so this is something of an international incident, which Sam Lawler has been documenting in this epic thread over the past few months.</blockquote>

"How We Got Here -- A vision brewing for 13 years:

2011: Georges [Labreche] stumbles on what would become his favorite SMBC comic, thank you Zach!
2020: Georges joins the OPS-SAT-1 mission control team as a Spacecraft Operations Engineer at the European Space Agency (ESA). Visions of running DOOM on a space computer intensifies.
2023: The reality of a 2024 end-of-mission by atmospheric re-entry starts to hit hard. The spacecraft's impending doom (see what I did there?) is a wake-up call to get serious about running DOOM in space before it's too late.
2024: Georges has been asking around for help with compiling and deploying DOOM for the spacecraft's ARM32 onboard computer but isn't making progress. One night, instead of sleeping, he is trapped doomscrolling (ha!) on Instagram and stumbles on a reel from Ólafur [Waage]'s "Doom on GitHub Actions" talk at NDC TechTown 2023: Playing Video Games One Frame at a Time. After sliding into the DM, the rest is history."

    <link>https://www.thespacereview.com/article/873/1</link>
    <dc:creator>jm</dc:creator><description><![CDATA[The original "rapture of the nerds":

<blockquote>[Fedorov's] thought was powerfully shaped by both Orthodox Christianity and Hegelian philosophy. [...]

Rather than passively waiting for God to bring on the Millennium, being a good Christian meant participating in the building of heaven on Earth. It was the way in which he expected this to come about that really separated Fedorov from the others. In his thinking there is only one evil in the world that really counts, death. Moreover, rather than being accepted as a part of “the human condition,” part of the human mission is the technological conquest of death. This means not only achieving immortality, but restoring all the people who have ever walked the Earth to life so that they may share the gift as well, making the heaven of the afterlife a physical reality. [...]

To help bring the dead back to life, Fedorov believed that humanity would eventually launch expeditions across the cosmos to recover particles that once belonged to their ancestors in order to reconstitute their bodies. Additionally, since Earth would not be big enough to accommodate all of the people who had ever lived at once, room would be found for them on other planets.</blockquote>

"If you are reading this achievement, Gabe Newell has successfully launched Gnome Chompski into space. If you did not also receive the achievement 'Manufacturing Ascent', Newell has abandoned his plans to shoot Noam Chomsky into space."

...There's an Amelie-inspired achievement for picking up the gnome at the start of [Half Life 2: Episode Two] and bringing it all the way to the rocket at White Forest Base, an arduous task involving lots of item juggling and repeated cramming of the gnome into a crevice in Episode Two's muscle car. Similar challenges made their way into Alyx and Left 4 Dead 2 as well.</blockquote>

    <dc:creator>jm</dc:creator><description><![CDATA[The Starlink light-pollution shitfest continues to get worse:

<blockquote>A responsible entity would address the problems they're actively creating and exacerbating before accelerating their launch schedule. A responsible entity would ask for the approval of all affected parties before proceeding further. A responsible entity would honestly and accurately address the real issues at hand, and would demonstrate that they've listened to communities beyond their own through their actions.

On the other hand, an exploitative entity would pay lip service to the communities they affect while continuing to actively harm them. They would ramp up their launch schedule. They would continue to send up offensive, unaltered satellites while putting minimal effort into solving problems that have been raised. They would invite consultants, but would squash any objectionable voices. They would distort the truth about concerns that have been raised. They would put their business interests — such as lucrative potential government contracts — ahead of any human interests. And they would deflect criticism by running PR campaigns that draw attention away from the real issues.</blockquote>

    <dc:creator>jm</dc:creator><description><![CDATA[from 'Frontiers of Engineering: Reports on Leading-Edge Engineering' from the 2016 Symposium, published by the National Academies Press, regarding the algorithms used by SpaceX for their autonomous landings:

<blockquote>The computation must be done autonomously, in a fraction of a second. Failure to find a feasible solution in time will crash the spacecraft into the ground. Failure to find the optimal solution may use up the available propellant, with the same result. Finally, a hardware failure may require replanning the trajectory multiple times.

A general solution to such problems has existed in one dimension since the 1960s (Meditch 1964), but not in three dimensions. Over the past decade, research has shown how to use modern mathematical optimization techniques to solve this problem for a Mars landing, with guarantees that the best solution can be found in time (Açikmeşe and Ploen 2007; Blackmore et al. 2010).

Because Earth’s atmosphere is 100 times as dense as that of Mars, aerodynamic forces become the primary concern rather than a disturbance so small that it can be neglected in the trajectory planning phase. As a result, Earth landing is a very different problem, but SpaceX and Blue Origin have shown that this too can be solved. SpaceX uses CVXGEN (Mattingley and Boyd 2012) to generate customized flight code, which enables very high-speed onboard convex optimization.</blockquote>

Reporters and editors from media outlets including television and newspapers had access to such documents from dozens of manufacturers while working on stories about the first lunar landing.

These press kits are beautifully prepared, with stunning artwork and fascinating period photographs.

It's taken me fifteen years of collecting to amass what I believe to be the most complete collection of Apollo 11 press kits in the world. I'm always on the hunt for more, so please contact me if you have any.

Now, in honor of the 50th anniversary of the Apollo 11 mission, I've digitized my collection to make it available to scholars, marketers, Apollo buffs, and fans of graphic design. </blockquote>

    <dc:creator>jm</dc:creator><description><![CDATA[<blockquote>The study took into account possible genomic and cognitive changes between the two [twin] brothers. These findings were recently clarified by NASA, which indicated that 93% of Scott Kelly’s genes returned to normal after he returned to Earth while the remaining 7% points were missing. These were attributed to “longer-term changes in genes related to his immune system, DNA repair, bone formation networks, hypoxia, and hypercapnia.”

In other words, in addition to the well-documented effects of microgravity – such as muscle atrophy, bone density loss and loss of eyesight – Scott Kelly also experienced health effect caused by a deficiency in the amount of oxygen that was able to make it to his tissues, an excess of CO2 in his tissues, and long-term effects in how his body is able to maintain and repair itself.</blockquote>

<blockquote>Shaped a bit like a disco ball, the Humanity Star is a 3-foot-wide carbon fiber sphere, made up of 65 panels that reflect the Sun’s light. The satellite is supposed to spin in space, too, so it’s constantly bouncing sunlight. In fact, the probe is so bright that people can see it with the naked eye. The Humanity Star’s orbit also takes it all over Earth, so the satellite will be visible from every location on the planet at different times. Rocket Lab has set up a website that gives real-time updates about the Humanity Star’s location. People can find out when the satellite will be closest to them, and then go outside to look for it.  The goal of the project is to create “a shared experience for all of humanity,” according to Rocket Lab.</blockquote>

    <dc:creator>jm</dc:creator><description><![CDATA[<blockquote>If you’ve ever watched a rocket launch, you’ve probably noticed the billowing clouds around the launch pad during lift-off. What you’re seeing is not actually the rocket’s exhaust but the result of a launch pad and vehicle protection system known in NASA parlance as the Sound Suppression Water System. Exhaust gases from a rocket typically exit at a pressure higher than the ambient atmosphere, which generates shock waves and lots of turbulent mixing between the exhaust and the air. Put differently, launch ignition is incredibly loud, loud enough to cause structural damage to the launchpad and, via reflection, the vehicle and its contents.  To mitigate this problem, launch operators use a massive water injection system that pours about 3.5 times as much water as rocket propellant per second. This significantly reduces the noise levels on the launchpad and vehicle and also helps protect the infrastructure from heat damage. </blockquote>

The photos taken from space cameras are no more fake or false than the photos taken from any camera. Like all photos they are a visual interpretation using color to display data. Most space photos have information online about how they were created, what filters were used, and all kinds of interesting details about processing.  The discussion about whether a space photo is real or fake is meaningless. There's no distinction between photoshopped and not. It's a nuanced view but the nature of the situation demands it.</blockquote>

So assuming the mission continues well, in 2014 the Rosetta Probe will land on Comet 67P/Churyumov-Gerasimenko, where it will measure the comet's molecular composition. Then it will remain at rest as the comet orbits the sun for hundreds of millions of years. So somewhere in the solar system, where it is safe but hard to reach, a backup sample of human languages is stored, in case we need one.</blockquote>

As jwz says: 'The Rosetta Disc is now safely installed on 67P/Churyumov-Gerasimenko.'

On Earth, gravity pulls bodily fluids down toward the feet. That doesn’t happen in space, and it is thought that extra fluid in the skull increases pressure on the brain and the back of the eye.</blockquote>

    <dc:creator>jm</dc:creator><description><![CDATA['Heavily tinted blue paintings form space stations, spacesuits, and rockets just after blast. Michael Kagan paints these large-scale works to celebrate the man-made object—machinery that both protects and holds the possibility of instantly killing those that operate the equipment from the inside. To paint the large works, Kagan utilizes an impasto technique with thick strokes that are deliberate and unique, showing an aggression in his application of oil paint on linen.  The New York-based artist focuses on iconic images in his practice, switching back and forth between abstract and representational styles. “The painting is finished when it can fall apart and come back together depending on how it is read and the closeness to the work,” said Kagan about his work. “Each painting is an image, a snapshot, a flash moment, a quick read that is locked into memory by the iconic silhouettes.”'

    <dc:creator>jm</dc:creator><description><![CDATA[<blockquote>So, here are the facts as we understand them: Mars One has almost no money. Mars One has no contracts with private aerospace suppliers who are building technology for future deep-space missions. Mars One has no TV production partner. Mars One has no publicly known investment partnerships with major brands. Mars One has no plans for a training facility where its candidates would prepare themselves. Mars One’s candidates have been vetted by a single person, in a 10-minute Skype interview.

“My nightmare about it is that people continue to support it and give it money and attention, and it then gets to the point where it inevitably falls on its face,” said Roche. If, as a result, “people lose faith in NASA and possibly even in scientists, then that’s the polar opposite of what I’m about. If I was somehow linked to something that could do damage to the public perception of science, that is my nightmare scenario.”</blockquote>

    <dc:creator>jm</dc:creator><description><![CDATA[Metrics rule the roost -- I guess there's been a long history of telemetry in space applications.

<blockquote>
To make software more visible, you need to know what it is doing, he said, which means creating "metrics on everything you can think of".... Those metrics should cover areas like performance, network utilization, CPU load, and so on.

The metrics gathered, whether from testing or real-world use, should be stored as it is "incredibly valuable" to be able to go back through them, he said. For his systems, telemetry data is stored with the program metrics, as is the version of all of the code running so that everything can be reproduced if needed.

SpaceX has programs to parse the metrics data and raise an alarm when "something goes bad". It is important to automate that, Rose said, because forcing a human to do it "would suck". The same programs run on the data whether it is generated from a developer's test, from a run on the spacecraft, or from a mission. Any failures should be seen as an opportunity to add new metrics. It takes a while to "get into the rhythm" of doing so, but it is "very useful". He likes to "geek out on error reporting", using tools like libSegFault and ftrace.

Automation is important, and continuous integration is "very valuable", Rose said. He suggested building for every platform all of the time, even for "things you don't use any more". SpaceX does that and has found interesting problems when building unused code. Unit tests are run from the continuous integration system any time the code changes. "Everyone here has 100% unit test coverage", he joked, but running whatever tests are available, and creating new ones is useful. When he worked on video games, they had a test to just "warp" the character to random locations in a level and had it look in the four directions, which regularly found problems.

"Automate process processes", he said. Things like coding standards, static analysis, spaces vs. tabs, or detecting the use of Emacs should be done automatically. SpaceX has a complicated process where changes cannot be made without tickets, code review, signoffs, and so forth, but all of that is checked automatically. If static analysis is part of the workflow, make it such that the code will not build unless it passes that analysis step.

When the build fails, it should "fail loudly" with a "monitor that starts flashing red" and email to everyone on the team. When that happens, you should "respond immediately" to fix the problem. In his team, they have a full-size Justin Bieber cutout that gets placed facing the team member who broke the build. They found that "100% of software engineers don't like Justin Bieber", and will work quickly to fix the build problem.

No, I am not a conspiracy theorist who believes that Armstrong’s moon landing was faked at some mysterious location in the Nevada desert. Armstrong reached the moon. But his accolades are undeserved because he was not first. All right-thinking Nunavummiut know this, because we know that Inuit regularly visited the moon for centuries.

David Iqaqrialu said as much in a heated exchange in the Nunavut legislature on May 6, 2002. We know it was heated because he prefaced his remarks by telling the Speaker, “I am starting to get hot under the collar...”

He then went on to say, as reported in Hansard, “...it is not really related to the question that I posed, but this is background material. Inuit had reached the moon quite some time ago during the shamanistic ages, prior to the Americans reaching it with their machines and finding out it wasn’t what they thought it was.”
