While we're waiting for Those Pictures, here are a couple of shots of LCROSS from our campus observatory last night (0221, 027 UT on 15 July). 4 minute exposures tracking expected motion from the Horizons ephemeris, within 20 degrees of the southern horizon and fighting summertime haze as well as city lights. I wanted to catch it before its inclined orbit takes it too far south, after which it spends a week or so as a predawn object. The range was about 563,000 km, and the Centaur is no bigger than a CSM/LM combination, so this is a more difficult target than spotting an Apollo enroute was. (On the other hand, nobody had CCD imagers in 1969).

For those hoping to see the impact; here're the Moon phases for October 2009:
http://www.moonconnection.com/moon-october-2009.phtml A cadre of professional astronomers using many of the Earth's most capable observatories is helping maximize the scientific return from the LCROSS impacts. These observatories include the Infrared Telescope Facility and Keck telescope in Hawaii; the Magdalena Ridge and Apache Ridge Observatories in New Mexico and the MMT Observatory in Arizona; the newly refurbished Hubble Space Telescope; and the Lunar Reconnaissance Orbiter, among others. I'm also looking forward to what images amateur astronomers will come up with. NASA plans a Citizens' science website for those... |
