To get started tracking LCROSS from your own telescope and computing system,
2. Enter “LCROSS” as the target body and other pertinent data
3. The JPL program will generate a set of coordinates that can be inserted into the tracking system of your backyard telescope.
4. It is also suggested you join the LCROSS_Observation discussion group at Google groups, which puts you in touch with NASA's LCROSS Observation Campaign.
The tentative time of impact of LCROSS with the Moon is 11:30 Universal Time (UT) on October 9, 2009. Just before that time, the 2,300-pound (1,043-kilogram) Centaur motor upper stage will impact a region on the Moon's south pole.
As the Centaur vehicle speeds along at about 5,600 miles per hour (9,000 kilometers per hour) the impact with the Moon should cause, as estimated by NASA, about 317 metric tons (350 tons) of ejecta plume raising up above the lunar surface about 10 kilometers (6 miles).
LCROSS will image this impact and the resulting plume. It will then be directed to also impact the Moon.
You think you have a disaster recovery plan?
Think again. Most businesses only have PART of a DR plan - and this spells business disaster in the event of an IT disaster.
