An auto rotating rotor like on a gyroplane or a helicopter doing an engine out decent?

From the NASA page: "Control fins would open on the side of the capsule, too, to keep it from revolving with the blades."
Yeah, 'cause pureed astronauts would suck.
Matthew Faunce
Just like the movie "The Incredibles" AMIRITE?

Intricate, expensive, undependable... all for a marginal benefit. NASA style!

It sounds very much like Rotary Rocket's landing to me.
Michael Crumpton
This has already been done. The roton spacecraft used rotors for deceleration and also could power the rotors for extended controlled flight. See it here: http://www.youtube.com/watch?v=7Kp63-an2ts&feature=related

And... autorotation? Any information at all on how they'd counter that?
Also seems a bit redudant in comparison to the VTOL capabilities of the Dragon 2.0 design; where escape, OMS, and landing are all integrated into one system.

Silly idea and how would you get the rotors to deploy? Where would they come from? You cannot steer a non powered helicopter. This is a half baked idea.
Anne Ominous
Yeah, right. "Parachutes ... require a water landing."
Not. See "Soyuz".

re; The Hoff
To get the rotors to deploy you release them into the airstream. Not unlike a parachute. The rotors would lay flat against the sides of the capsule until released. You can in fact steer an auto-rotating helicopter if the controls have not been compromised by whatever took out your engine. In fact if you have lost control of your anti-toque rotor auto-rotating improves your ability to control the helicopter during landing. While I prefer conventionally winged reentry and landing vehicles this is far better than just being at the mercy of the wind under parachutes.
