SpaceX NASA returning human spaceflight to United ...
curious 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.
