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).

On August 17, LCROSS took additional images of the moon and earth, as part of the process to calibrate its instruments. See page http://www.nasa.gov/mission_pages/LCROSS/main/index.html

Here's a Spaceflight article explaining the recent startracking-frenzy anomaly: http://spaceflightnow.com/lcross/090825fuel/ summary: Half the fuel is gone, but it should be just enough to complete the mission. LCROSS may have to cancel some activities not crucial to the mission to save the fuel for other unexpected contingencies. |
