An artistic impression of LCROSS impacting the Moon Surface.

NASA’s Lunar CRater Observation and Sensing Satellite (LCROSS) mission will come to a dramatic conclusion at approximately 4:30 a.m. PDT (7:30 a.m. EDT) on Friday, Oct 9, 2009, with the impact of the LCROSS Centaur upper stage rocket and four minutes later, the impact of the LCROSS Shepherding Spacecraft into Cabeus crater near the moon’s south pole.

Previously NASA altered the impact crater basing on chandrayaan data. 

Across California and Hawaii, hundreds of eyes will be trained on the moon, watching for the moment when a hi-tech orbiter – weighing more than 2 tonnes and travelling at 9,000kph (5,600mph) – plunges headlong into the lunar surface. The collision will throw a massive cloud of dust and debris up into space before, just a few minutes later, another, smaller, spacecraft follows suit and plummets to its doom.

The satellite and upper stage both are scheduled to hit a permanently shadowed crater of the moon, four minutes apart, at approximately 4:30 a.m. and 4:34 a.m. PDT(04:30 PM Indian Standard Time) on Friday, Oct. 9. NASA Television coverage begins at 3:15 a.m. PDT. At the time of posting this there are less than 24 hours left.

Are you disappointed that you can't view the live or moon doesn't appear in your country at that time, don't worry NASA is webcasting the NASA TV for all people round the world - click here for NASA TV

A live NASA TV Broadcast is planned for the LCROSS impacts starting at 6:15 a.m. EDT/3:15 a.m. PDT, Oct. 9(3.15 pm India), on NASA TV and www.nasa.gov/ntv.

The 1.5 hour broadcast includes:

• Live footage from spacecraft camera
• Real-time telemetry based animation
• Views of LCROSS Mission and Science Operations
• Broadcast commentary with expert guests
• Prepared video segments
• Views of the public impact viewing event at NASA Ames
• Possible live footage from the University of Hawaii, 88-inch telescope on Mauna Kea.
