Returns number of days between two date objects. The Lunar Prospector Impact Page Lunar Prospector has impacted the moon. Click to enlarge. The image is approx.
North is up.
Note that the libration will increase by about 1 degree by the time of the impact, so you will see more fore-shortening. The impact site is marked with an arrow. The impact is presently scheduled to occur at night while the moon is visible from Texas and Hawaii. The probability of success is thus low. A observer will need excellent conditions to see the debris plume which is not expeceted to be large, maybe 20 arcsec above the limb.
