Was in the South Bay this afternoon and drive by SpaceX HQ. So cool.

Read somewhere that Sam Adam’s had 66 lbs of hops on board. Now that’s science!

Can't believe space flight history was made yesterday and no one promoted this thread. We should all feel shame.

Dragon reached its intended target orbit, with altitudes as high as 590 kilometers above the Earth’s surface — flying farther than any human spaceflight since the Hubble missions.
That is pretty awesome

IDK who to blame, but there's a marketing exec somewhere that should be fired. I knew nothing about this until we stumbled upon the Netflix documentary a day before the launch.

The fact that a big part of the mission was to raise money for St. Jude makes the lack of marketing very confusing. Apparently they met their $200m goal, but $150m of that came from Isaacman and Musk. Probably some other big names in there too, meaning not much came from the general public.

I’m no conspiracy theorist, but some of those camera angles really looked green-screened.

I realize it was mostly the drone footage, but still looked odd.

All safely returned to Earth.

No one actually still likes George Takei, right? I know he was the darling of the internet for years, but I feel like his general dickishness and questionable past are pretty well known.

Boeing and NASA believe they have identified the cause of the corrosion that stuck shut almost all of the valves in the Boeing Starliner's thruster system: humidity. Basically, it's really humid in Florida, and that humidity caused condensation near the valves that reacted with trace amounts of the nitrogen tetroxide oxidizer to make nitric acid, which corroded the valves.

If this indeed is as simple as humidity, it's a major :face: for Boeing's testing program. Boeing apparently did its testing for the Starliner's RCS system at the White Sands Missile Range in NM, which is about as low-humidity as you can get, and the one prior launch of the Starliner (that failed to reach the ISS due to software bugs) took place in December, when humidity in Florida is near its lowest. The second Starliner launch was supposed to be back in August (when I can say from personal experience that it's very humid in Florida), and the Starliner spent a couple extra days on the pad because the Russian Nauka module had just docked at the space station and caused its drama with unordered thruster firings. That meant the Starliner was exposed to ambient air for more time than was expected, and it looks like that was enough to rust up the valves.

NASA has started to shift some astronauts who were slated to fly on Starliner onto SpaceX missions. It's looking like this unmanned Starliner test flight probably won't take place before mid-2022, and the first manned flight might not be until 2023.

Yeah that's a real :face: if true. Any engineer knows that you test your equipment for the conditions it will be placed in. Huge oversight if true.

Seems that now that the SLS stacking is complete, now it's no longer November 2021 for Artemis 1 but February 2022.

Oh god. I didn't think about that. If their stomachs haven't been acclimated to that kind of spice. The thought that it's likely that astronauts have had to cope with violent diarrhea in a tiny prison floating through outer space, (with at least one, usually more astronauts of both sexes) with no proper toilet, not to mention the odor, gives me anxiety.

What if you get sick in the middle of a launch or descent? Yeesh. I'm sure there are designs with those things in mind.

Speaking of toilets, there was some urine leakage for the Crew Dragon's toilet during the recent Inspiration4 flight. SpaceX found that a urine tube under the vehicle's floor came loose and leaked pee. SpaceX has fixed the problem for the Dragon that is currently awaiting launch, but the issue is still there for the Dragon that is currently berthed at the ISS. So when that Dragon returns later this month, the crew will have to rely on "undergarments" if they need to go between undocking and splashdown (a time that can range from around six hours to over a day).

The SpaceX Crew Dragon has jettisoned its "trunk" and just ended a nominal deorbit burn. Splashdown should take place slightly after 10:30 eastern time, or about 35 minutes or so from now. It is unknown whether any of the crew has been forced to piddle in their diapers due to the nonfunctional onboard toilet.

Dragon just safely splashed down. One of the four main chutes took a little longer than usual to fully inflate, but it was fullly open and working well before splashdown.

Might be some nice videos of this from folks in Florida. The NASA WB-57* that was observing on station had a view of a lovely, bright orange/purple trail as the Dragon went through the thick parts of the atmosphere.


* NASA operates the last three operational Martin B-57 Canberra aircraft in the world as high-altitude observation, testing, and scientific-research aircraft. Those birds are something like 70 years old at this point. Pretty impressive service life for an aircraft that first flew in 1953.
