So the Lunar Crater Observation and Sensing Satellite has one last sensing task which it will carry out tomorrow morning at 4:30 AM Pacific. That is to dig a big hole in Cabeus (proper) and see if there’s water there. Unfortunately for LCROSS, it doesn’t really have landing jets, which means it will dig a big hole and other instruments will check for water.
Unfortunately, the impact plume is expected to be not big enough for binoculars or cameras, but it will be big enough for large amateur telescopes.
NASA has a page on “where and how to observe the LCROSS impacts.”
