LCROSS Lunar Swingby Streaming Video (Launch +5 days)

      Two Perspectives of the LCROSS Lunar Swingby

      Approximately five days after launch, LCROSS performed a lunar swingby to enter into an elongated polar Earth orbit. This orbit positions LCROSS for impact on the lunar south pole (see mission overview video) on Oct. 9, 2009. Shortly after periselene, the time of closest approach to the lunar surface, the LCROSS science payload was switched on for the duration of one hour.

      During the swingby , the spacecraft's instruments calibrated by scanning three sites on the lunar surface. These sites were the craters Mendeleev, Goddard C and Giordano Bruno. They were selected because they offer a variety of terrain types, compositions and illumination conditions. The spacecraft also scanned the lunar horizon to confirm its instruments are aligned in preparation for observing the Centaur's debris plume.

      The following videos show two perspectives of the LCROSS lunar swingby. The first video is taken from the LCROSS visible light camera and the animation is a 3-D is representation of the spacecraft based to actual telemetry recieved during the swingby. Both videos are condensed in timeframe.


"When once you have tasted flight, you will forever walk the earth with your  eyes turned skyward, for there you have been, and there you will always long to return."
