Well, poop.

After 26 straight successes, SpaceX fails to land Falcon 9 it wanted back

One of the grid fins got stuck, and at a bad angle. This imparted a pretty unfortunate roll, causing the booster to miss the landing pad. In fact, it missed Florida and landed in the Atlantic, not far from shore… crashed down, fell over *then* sank into the swamp. Fortunately the mission itself is, so far, successful, with the Dragon space capsule delivered to the proper orbit. This version of the Dragon will, hopefully, soon be transporting astronauts to the Space Station. Chances are that the booster is trashed, but not *destroyed.* So it will be recovered, analyzed and fixes made.
