Was ballast sled built and used - What mass, distance

Article says ballast sled added to design by SpaceX (with ref to Feb 2015 congressional testimony) - but did it ever get built and flown ? When was it cancelled ? Why ? What mass, travel, direction etc would it have had ? - Rod57 (talk) 15:38, 5 February 2022 (UTC)

The ballast sled was not implemented (along with the landing legs). It would have been used for precision land landings without using the parachutes. SpaceX removed the ability to land propulsively because of the development and testing time. Crew Dragon only lands by water splashdown. No showbiz mike (talk) 13:50, 16 April 2022 (UTC)

Here is a NASA document that includes a Crew-2 capsule subassembly listing that doesn't mention a ballast sled system. https://www.nasa.gov/sites/default/files/atoms/files/nac_ccp_status_dec_6_2018_non-sbutagged.pdf No showbiz mike (talk) 14:09, 16 April 2022 (UTC)

Thanks. A very interesting presentation, including the capsule assembly timelines & diagrams. - Rod57 (talk) 09:46, 10 November 2022 (UTC)

Could have more details on pressure vessel and service structure in capsule

Could have more details on pressure vessel and service structure in capsule, including details of propellant and life support systems. (more detailed than [1]) - Rod57 (talk) 09:51, 10 November 2022 (UTC)

Moon

Could this vehicle fly to the Moon? 2001:9E8:CADA:DF00:144E:183C:F952:F358 (talk) 19:45, 11 September 2024 (UTC)

Not without modifications. --mfb (talk) 16:52, 28 November 2024 (UTC)

Crew Dragon capacity

All orbital launches of SpaceX's crew dragon have included four seats. While there were empty seats in three missions, those missions still had a capability to carry four astronauts. Crew Dragon flew uncrewed in Demo-1. Both Demo-2 and Crew-9 launched with two empty seats, although Crew-9 will be returning with 4 astronauts.

If SpaceX were to launch a crew dragon with only two seats, then stating the capacity is 2-4 would be accurate, but that has not been the case so far. AmigaClone (talk) 12:10, 28 November 2024 (UTC)

I've added a sentence to the Crew Dragon paragraph regarding crew capacity. Since NASA and SpaceX both say it is capable of seven, It is worth mentioning, but I also said that this has not been proven as of November 2024 and the infobox should remain with 4 as it is now.

See page 20 of the Commercial Crew document Alpacaaviator (talk) 16:02, 30 November 2024 (UTC)

When I put the normal capacity as 2-4, I meant it as a minimum of two and a maximum of four. Ahead of the Crew-9 mission, Nick Hague gave a great interview on the NASA podcast about the work that had to take place when it went from a four to a two person mission and he had to take on the pilot and the commander role as a single person, the challenges of that, the limitations of what Aleksandr Gorbunov could assist with. Future Dragon passenger Chun Wang also remarked that while there’s an impression that the Dragon is “fully automatic”, there’s still a lot of procedures that the crew need to follow. It paints the picture that there’s a lot of supervision of the computers, and in NASAs opinion, the supervisory workload is too high for one person alone.
