Can someone explain this detail from the DM1 presentation? Landing Legs???
Quote from: jpo234 on 08/28/2018 06:41 amCan someone explain this detail from the DM1 presentation? Landing Legs???NASA, in these slides, used a generic, and out-of-date, SpaceX flow diagram for Crew Dragon.People seem to be forgetting that landing legs were only deleted from NASA missions AFTER the design for Crew Dragon was almost completely done.

Some unexpected g-loads & vibrations might cause difficulty to rise their hand(s) up to the dash board and press or pull anything there.Crew Dragon is highly automated. During the ascent phase the crew really isn't crew. They are passengers. The entire ascent to orbit is fully automated, including all the abort modes. No silly abort-mode switches or joysticks (a la Shuttle) or manual abort handles (a al Apollo). None of that stuff. If a comsat can get to orbit fully autonomously on a regular F9 than why should Crew Dragon be different? By the time the crew finally realizes something is wrong with the rocket the computer has already executed the proper abort mode. Computers far out-perform humans in this regard. Why do you think ranges are switching over to AFTS for example?The only manual intervention modes available are on-orbit, when you are not hampered by high G-loads. Like manually intervening in the approach to ISS or manually intervening in the final phases of docking. That why there are controls for the RCS engines. There is also an option to do a manual de-orbit. But the descent phase itself, including entry and the parachute stages is again fully autonomous.

Host: And this might get into the weeds a little bit, but how much-- so, these new spacecraft, are they going to be-- because, for example, the Russian Soyuz, largely automated, automated docking, you know, the crew has some tasks on board, mission control is largely monitoring. Shuttle was a lot of, you know, onboard flying for the crew and stuff like that. Where are these vehicles going to kind of fall and are they-- again, are they different? Kathy Lueders: So, I think both of them are fairly autonomous. If you think about it, it kind of goes back to once again the commercial concept. Right? If you're a company that wants to have control over how your vehicle is operating and with the capabilities they have today, with computer-- the processing capability and everything else-- they're really developing very sophisticated autonomous rendezvous and docking and reentry capabilities. And so, really crew is there as a monitoring function and back up in case some-- like something really goes wrong, but these, they're really-- both companies are designing their spacecraft to be two-fault tolerant to a failure. All along the way. Very robust, which is really our intent. We wanted to have very robust vehicles. Right? Very robust vehicles. We asked them to design their vehicles to be two-fault tolerant and to not have crew as a control. So, we-- that was a-- kind of goes back to safe and reliability being kind of important tenets and the companies have really come through. They have different strategies for how they do that and they'll be checking out that autonomous capability on their first demonstrations because they'll be uncrewed [phonetic]. They'll be uncrewed demonstrations to the ISS, so that will kind of prove out that autonomous capability. I always tell people I'm-- I know we've got self-driving cars out there, but I'm really hoping that before they roll out their first commercial one, the first commercial self-driving crew vehicle that's being bought by the government is going to be a crew transportation vehicle that's going to the ISS and so--
Just a little detail: Tesla Model X will carry first astronauts flying in SpaceX’s Dragon spacecraft to launch pad (Electrek.co)
The strongback is on the wrong side of the vehicle in the picture and the slide wire escape system doesn't appear to have been moved up to the CAA level.

Yeah, that was clear to me. But I felt it important that people see the block V Falcon 9 in all its glory.
Just had a question..which probably borders on being silly....For context, I was visualizing commercial crew up and running with a 7 person crew at ISS. If this where to entail 6 month rotations between CC and 6 month rotation between Soyuz and a mid stagger between CC and Soyuz exchange....what would this do for contingency planning for emergencies such as medical or a capsule repair issue. I eventually talked myself into these scenarios being very rare but still ended up wondering...if an automated empty Dragon 2 was sent early to the ISS...With Dragon 2 seating...would someone in a Boeing suit or an Orlan suit be able to at least sit in a Dragon 2 seat and be buckled in?If they can be buckled in...would it be at least possible to use an adapter for the Dragon 2 umbilical to supply consumables to the other 2 suit types to enable getting someone home (under admittedly a far fetched scenario)?

If that was not possible (for time reasons) then the next best option would be to come down without a suit. The suits are only for emergency depressurization, a very unlikely scenario and I wouldn't be surprised if the astronauts would be fine with that after a few flights proving reliability of both Dragon and Starliner.

Shotwell: decline in GEO business is not a “crushing blow” for us. Seeing strong growth in DOD business, but also later with commercial crew: “7 billion potential payloads”
Based on the Gwynne Shotwell quote from Jeff Foust's tweet:QuoteShotwell: decline in GEO business is not a “crushing blow” for us. Seeing strong growth in DOD business, but also later with commercial crew: “7 billion potential payloads”Sounds like there will be space tourism flights using Crew Dragon. I wonder if the lunar flyby plan will be restored, just like how Gwynne saved FH from cancellation.
