HD VIDEO: Curiosity's descent onto Mars as filmed from orbit
Absolutely incredible! This was apparently compiled into a video using images from the MARDI Descent Imager. What you see at the beginning is the heat sheild being shed. Followed by the rover's P.O.V. descent, via sky crane.
UPDATE: Here's a new "smoothed" version that's easier to follow, visually. Props to Boing Boing.
