Yup. The Soyuz landing capsule uses solid fuel retro-rockets at the very last second to slow down, but even then it is apparently a rather unpleasant bump.

- tomswartz07 12y agoWhat's interesting here is the difference: Soyuz uses a 'suicide burn' that releases a ton of delta-V in a short amount of time. From the video, it seems that Falcon uses a progressive burn as it approaches. They also mention that they can restart it up to 3 times in atmosphere.
- rspeed 12y agoThe third burn here is also a suicide burn. The first one is to change its path and the second is to prevent it from falling too fast.
