September 11, 2009: LCROSS spacecraft impact crater to be announced

Soon we'll know exactly where LCROSS is headed. In three days an announcement will be made on exactly where the spacecraft will head to on its collision course with the Moon. 30 days after today it will hit the impact area, a big plume of something (hopefully with water ice) 9.6 km in height will rise from the Moon, and everybody will be keeping an eye on it in order to learn as much as possible about the makeup of the Moon thanks to this one-time event.

Note that LCROSS burned up about half of its fuel by mistake last week so it has just barely enough to accomplish the mission, but if everything else goes as planned then it should be a 100% success.

The most frequent updates to LCROSS can be seen on Twitter. All the updates there are written from a first-person point of view.
