Would this chair support astronaut during launch in Crew Dragon

1.) Chairs needed to be custom molded / adjusted for the astronauts. There's stories of people sitting down in bathtubs of foam to create the perfect shape. That is an extra comfort of the Soyuz ...

What standard was used by NASA to certify the Dragon capsule controls as safe for crewed flight?

As I am not privy to the contractual interactions between NASA and SpaceX, I cannot say with an absolute certainty that NASA and SpaceX had astronauts, pilots, etc. evaluate the vehicle beforehand ...

Could Dragon 1.0 be used as an emergency Earth return vehicle

It's better than nothing, of course. I don't think it has carbon scrubbers but other than that it's climate controlled and pressurized (Elon: "If someone were to stowaway on the unmanned version of ...

Will the 2018 Mars Dragon Lander be the largest lander on Mars to date?

Yes, by quite a bit. Right now the heaviest object soft landed on Mars is Curiosity, as you noted. The mass of it is 900 kg. The Red Dragon is 6400 kg, plus payload of up to 2000 kg (Maybe more for ...

What payload was expected for the 2018 Mars Dragon flight ("Red Dragon")

Aviation Week seems to be the best source right now. A few interesting bits: NASA is spending up to $30 million in support, mostly to help gain information for EDL on Mars. A photo might be taken ...

Why is the Dragon small compared with the Falcon 9 LEO payload

First of all, the difference in capacity is actually greater than you included. Dragon launches without a fairing, thus there is an increased capacity as a result of launching without the fairing. The ...

Does Dragon have any timeframes during launch where there is not a planned survivable abort mode?

No. One of NASA's requirements for Crew Dragon and Starliner is that they are able to provide a full envelope abort window for the launch. 5.6.1.2 The CCTS shall provide abort capability from the ...

How does the landing accuracy of Dragon (under parachutes) compare to Soyuz?

No values for Soyuz or Dragon on wiki splashdown page, but the lake listed for the one Soyuz water landing seems to be like 20x40km. NASA shows the Soyuz landing zone as 25km wide. There is a thread ...

Do astronauts on the ISS ever secure unpressurized cargo with an EVA to then be brought inside through an airlock?

Is the Dragon Mono-Stable?

From this answer to this question, we can see that there are two stability modes used. The capsule by itself is mono-stable, with the heat shield pointing towards the ground. The second mode is with ...

I assume that the Falcon second stage gets into something fairly close to the rendezvous orbit, but Dragon has just about the same maneuvering capability as Soyuz does. I’ve heard the Soyuz ...

What payload was expected for the 2018 Mars Dragon flight ("Red Dragon")

Reason for different "cone angles" of different space capsules?

The target lift-to-drag ratio (L/D) also plays an important role. A high L/D provides greater aerodynamic control authority during hypersonic entry, providing engineers with greater flexibility in ...

What prevents the current Dragon capsule being used for crew?

There is a minimal life support system, in the sense that it is pressurized and they carry animal experiments that do not have their own life support systems. But it is not designed to handle the load ...
