Target crater selected for Lunar Impact of LCROSS Spacecraft

NASA has identified the spot where it will search for water on the moon. The selected crater is an optimal target for evaluating if water ice exists at the lunar south pole. Briefing participants are Daniel Andrews, LCROSS project manager, Anthony Colaprete, LCROSS principal investigator, and Jennifer Heldmann, lead for the LCROSS observation campaign. Following the news briefing Friday, more will be reported here.

On Tuesday, June 23,
LCROSS executed a swingby of the Moon.
LCROSS reached periselene, its closest approach, at 10:30:33 UT, with the spacecraft passing 1,988 miles (3200 km) from the Moon.

The flyby resulted in a gravity assist from the Moon which put LCROSS into its cruise Lunar Gravity Assist Lunar Return Orbit (LGALRO). The swingby also provided mission scientists with an opportunity for instrument calibration and the return of images from the far side of the Moon. See video and additional photos.

LCROSS and LRO launched on Thursday, June 18 @ 5:32pm Eastern Time. Projected Impact at the lunar South Pole: Oct 9, 11:30 UT (7:30 EDT, 4:30 PDT) -- See News Release.
