I'm glad that the space age has been rekindled. I wish Europe would do something similar.
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

Do they have to stay seated & buckled the whole 19 hours? Dare I ask how they eat or go to the bathroom on the 19 hour trip?

#123And right as the booster was landing on the ship the satellite feed cut out.
That's quite normal. It happens on pretty much every launch to some extent. Something to do with vibrations causes by the landing burn and directional dishes
They'll release the whole footage once they get it back from sea. I would also like to see more video from inside the capsule too.

#124I am an old person reflecting... It is amazing to me how we can do something like this on one hand (it makes me cry), yet have George Floyd on the other (that makes me cry also).

No, there's room for them to get "up" and take their suits off. Eating is no problem, the food is basically MREs. There is a toilet.

Non-toxic would be better than toxic. What would be the options? Compressed cold-gas (which don't have much kick, and require compressed gas which carry their own dangers). You could go with a monoprop Hydrazine which would eliminate half the toxic stuff. There are also some new developments here: hydroxylammonium nitrate (HAN)/water/fuel ? No idea of the trade offs there. Biprop hydrocarbon/gaseous compressed oxygen…
> What would be the options? Soyuz uses straight hydrogen peroxide, I believe, 82% concentration. For 3 tons capsule it takes 30 kg of peroxide - monopropellant - to land. Buran is still the example of a high tech option - it used LOX and kerosene for RCS, the biggest trick was to keep LOX liquid for a month-long missions. It was done with mid-1980 technologies. Kliper planned to use LOX and ethanol. The craft wasn't…
How much HTP would you need for the launch escape system?
Re: SpaceX successfully launches two humans into orbit
#128It 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…
A new normal has just been defined. Amazing to see.
"Thank you for flying with Falcon 9 today", as though it's an airplane.

#129Does anyone know if there's an interactive map where we can track where Dragon is in context of the earth?

We're a big country. Plenty of space to do multiple things at once
