#272curious those "NACA-duct-looking" things at the bottom of the capsule doesn't seem to have any holes... what are they for? edit: part of controlled airflow maybe when coming down in reverse/re-entry?
They are the SuperDraco thrusters, for launch escape. There are no holes because there are covers that get blown away by the thrusters, to protect them during re-entry if they are not used.
Ahh that's right I think I've seen footage of them firing before. The cover thing makes sense, thanks.

Exactly. The odds are not what I'd like them to be.
So, never flying on new vehicle or flying a vehicle uncrewed for 40 years is the only option you consider save? That seems like incredible pessimism to me.
Maybe somewhere between those two extremes.

#275The interior design of the capsule looks so futuristic and cool - closer to Star Trek than Soyuz.
A stark contrast to Soyuz, which has numerous unfinished, sharp edges exposed inside the crew compartment.

#276Here is pretty accurate in terms of spacecraft UI docking simulator: https://iss-sim.spacex.com/ Astronauts will be using similar for manual piloting demo before docking.
I have tried and barely succeeded, I just hope those are not real controls. Those should be either automated or they should consult someone from gaming industry. Sorry to say UX controls are terrible (saying from gaming position).
While I'd argue that the controls (at least for rotation, possibly also for translation) should be inverted, the controls are actually pretty decent.
Try running it again but focus on zeroing the pitch, roll, and yaw first before moving on to the x, y, z. Once you have rotation under control, zero in your X, Y positional offsets until you are lined up. Finally burn your Z and then slow as you approach, all the while keeping the X, Y, Pitch, Roll, Yaw as close to zero as possible.
The big issue is that fine grain translational motion is nigh impossible while dealing with any type of rotational motion. Once you kill the rotational motion, it's intuitive like using crane-game controls.

Those space suits look so cool, don't they?
I don't know, they look kitschy to me - as if someone designed them just to look 'cool' and futuristic instead of utilitarian, like a fashion statement.
I think they're both. It feels like they went for utility, but also kept watching Kubrick's 2001 for inspiration.

#278Does anyone else feel super excited? I guess this was the feeling my parents had when they watched men landing on the Moon...
Today is a melancholy feeling. Happy to see SpaceX sending people to space, but sad a decade was lost. EDIT: I spoke about that we had a regression, I meant that NASA lost a capability and just got it back.
A decade? More than four decades. The shuttle was never really about anything else than near earth orbits, this is the first time in a very long time that we are just possibly looking to expand the envelope.

#279I watched the first Space Shuttle launch live, I watched Challenger live. I watched the last shuttle launch live. I was sad then, realizing that America was losing launch capability on that day. I can't tell you how exited I am to watch America's return to launch capability. Edit: Disappointed at the scrub, but I know a lot of these weather rules were put in place because of Challenger, so I understand. Looking forwa…
Sorry to hear you guys haven't had lunch for so long
We need to bring down our national BMI.

I understand this sentiment, but if SpaceX pulls this off, it's going to be an order of magnitude cheaper and more sustainable than the incredibly awesome but one-off and flashy Apollo (or even shuttle) missions. Crew Dragon is not visually BIGGER than a Saturn V, but it is in a lot of ways a firmer footstep into space than we've ever taken before. SpaceX's program isn't going to dry up as soon as the cold war is ove…
> it's going to be an order of magnitude cheaper Soyuz is $60m per passenger I think? Are they saying dragon would be $6m per passenger per launch? I find that hard to believe...
You cut off the bit where it was made clear that was in comparison to the Apollo and Shuttle missions. Please don’t knowingly take quotes out of context and use them like that. It’s really unpleasant behaviour.
