I'm actually surprised they use a touchscreen interface, and they will use that for the manual docking too! https://i.imgur.com/YKiqIqO.jpg

I understand it runs Chromium code and that the UI is written in Javascript. https://space.stackexchange.com/questions/9243/what-computer...

Wow, had I known that this whole thing would have been a lot more nerve wracking.

Can a SpaceX Crew Dragon launch from a non-SpaceX rocket? If NASA decides to diversify, can they buy a Crew Dragon and stick it on an Atlas V or Delta IV? It seems not.

The Wikipedia page for Crew Dragon says "The spacecraft launches atop a Falcon 9 Block 5 rocket and returns to Earth via an ocean splashdown." [1]

The Wikipedia page for Boeing Starliner says "It is designed to be compatible with four launch vehicles: Atlas V, Delta IV, Falcon 9, and Vulcan." [2]

It is hard to convey how "sustainable" this feels to me. For the first time, humans have gone into orbit in a spacecraft that was designed from the ground up to be a commercial venture. All of the NASA missions prior to this have an ambience of "uneconomical but useful". Even the shuttle, which was supposed to be this cost effective space truck, turned out to be not even close. And the last thing I'm feeling is the a…

The ISS is definitely not a commercial project. There are lots of reasons for the ISS to exist, and they have changed over time, but it has never been a money-making venture.

I think one of the main priorities is military supremacy. It might not appear as that from a bit away, but that should not be overlooked. NASA's boss really highlighted some of that indirectly today as well with the increased funding to build out Space Force and some of that money goes to SpaceX obviously. So commercial, yes, but not like a car. More like a tank or fighter jet.

I think the comparison between Elon Musk and Henry Ford starts to break down a bit towards the end of your comment. Elon Musk tweets plenty I don't like, but he's far from a Nazi.

he? maybe you should read again the post of your parent....

I'm actually much more confused by your comment than the parent of yours.

The WTO is run by a very specific brand of economists that don't see the value in a country subsidizing an industry to maintain local expertise in that industry. I for one disagree pretty heavily with this ruling.

The WTO is run by bureaucrats who enforce the terms of the membership agreement. If national governments think it's important to subsidize local industries then they should negotiate agreements to allow for that. Don't blame the WTO.

While it might make sense to provide an exemption for local industries that have critical defence or security implications, politicians may find themselves tempted to expand the scope of that to include other "national interest" products, like yoghurt:

I’m not super well informed on this, but is there any reason for sending humans to space at this moment in time (or for the next 20 years for that matter). The only reason my layperson understanding can think of is mining minerals in space, but I fail to see why robots wouldn’t be able to adequately do the job. In fact wouldn’t sending humans make future space ventures even more costly and put people into unessisary…

> I fail to see why robots wouldn’t be able to adequately do the job.

Because they can't adequately do the job, even now, on Earth. Maybe they will, in 20 years. Right now, there are whole classes of missions for which the choice isn't between humans and robots, but between humans and not doing them at all.

- International travel (anywhere in the world in less than two hours) could be one of those things. - Asteroid mining

I think it's ridiculous that a rocket can fly up to 90km and return to Earth in a controlled landing in under 10 minutes. So cool.

Well, the escape velocity for Earth is 11.2 km/s...

Surely they don't want to being that fast ;)

Often you need to build the new thing before the business model emerges, because you can’t visualize or evaluate the latter until the former exists.

I think it's the general problem of infrastructure-like endeavors. "If you build it, they will come" absolutely applies to infrastructure.

Thinking of Europe, I have a feeling that it's just surreal that this launch is happening in America at the same time with the events in Minneapolis

There is an eerie echo of history here. The late 60's were the height of civil unrest in modern America. Robert Kennedy and Martin Luther King Jr. were assassinated as Apollo astronauts were preparing to land on the moon.

In a few years, when people watch this historic footage, you have to explain why everybody is wearing masks.
