LUNAR IMPACT UPDATE: NASA's LCROSS spacecraft and its Centaur booster rocket are on course for a Friday morning impact in crater Cabeus near the Moon's south pole. The Centaur will strike first on Oct. 9th at 11:31:19 UT (7:31:19 EDT, 4:31:19 PDT), followed by the LCROSS mothership at 11:35:45 UTC (7:35:45 EDT, 4:35:45). The spectacular double-impact, designed to excavate water frozen in the crater's shadowy depths, will be broadcast live on NASA TV. Amateur astronomers with 10-inch class backyard telescopes may be able to see debris billowing over the crater's rim. This is a big event!
