Watch LCROSS Moon Impact Live
10.08.2009  16:00


As you probably know, the NASA Lunar CRater Observation and Sensing Satellite's (LCROSS) Centaur upper stage is on a collision course for a crater near the South-pole of the moon called Cabeus after midnight tonight (which will be the early morning of Oct 9, 2009). The Centaur upper stage rocket carried both the LRO and LCROSS spacecrafts to Lunar orbit, and will remain attached to LCROSS until released for the impact trajectory. About 4 minutes after the empty upper stage strikes, the LCROSS spacecraft itself will pass through the resulting ejected plume, sending data back to Earth while sensing the particles and snapping pictures, and also impact the crater.

The exact time of the first impact (as of this writing) is Oct 9, 2009 at 4:31:19 PST. Read my earlier post for more details.

Want a cool place to watch the impact?

The point of this update is to announce:

Viewing at NASA-JPL at the Von Karman Auditorium is open to the public and the gates will open at 3:00 am PST (Oct 9, 2009). So if you live in Southern California, set your alarm early enough to allow you time to:

  1. Get some coffee
  2. Get to JPL (4800 Oak Grove Dr., Pasadena, CA 91109)
  3. Park
  4. And find your way to the Auditorium (there are signs pointing you there)


If you do not live in the L.A. area, there are other viewing parties around the USA, or watch it live online at NASA TV.

NOT how the moon will look tonight, this is just a picture I took of the moon on 4/3/2009


This is NOT how the moon will look tonight, because I took this picture back in April of this year. To see a moon phase calendar for October 2009 click here.
