We waited, we watched, and for the most part, we were disappointed. However the lack of visual fireworks in last week's "moon bombing" doesn't mean the mission was a scientific dud. Although the empty Centaur rocket stage that crashed in close proximity to the moon's South Pole didn't throw a huge plume of lunar debris up into the sunlight as researchers wanted and the Lunar Reconnaissance Orbiter snapped a few images of the crash site that shed some light on the situation anyway.
By the time of LCROSS mission, the empty rocket stage impacted the crater Cabeus in hopes that it will send a plume of lunar soil and, confidently, shooting high over the crater walls moreover into the sunlight. Following four minutes behind, the LCROSS spacecraft might take photos of the plume as well as beam them to Earth before also impacting the lunar surface. Although it is unclear whether the rocket stage threw any debris high enough to be spectroscoped by LCROSS and the LRO snapped thermal images of the impact sites immediately in 90 seconds after the two impacts occurred and images that might have great scientific significance.

Because of the lack of atmosphere on the moon, the LRO can orbit a mere thirty miles on top of the lunar surface, and as such can scan the moon's surface through an array of instruments, together with a thermal scanner dubbed Diviner. As the LRO passed in the clouds, Diviner detected impact sites into all four of its mapping channels. The LCROSS impact feature is thought to be far-off smaller than a Diviner footprint; therefore its detection suggests substantial local heating just about the impact sites.
That heating is noteworthy because it can help NASA researchers to find out how much water may have been there in the region of the impact sites. Though there is still no concrete evidence that vast, exploitable ice reserves stay alive on the lunar South Pole, the LRO photos must provide some idea of how much water may present near the surface where the LCROSS impacts occurred. An added developed analysis of the LCROSS mission's findings is supposed to be available in the coming weeks.
Diviner Thermal Maps: All four mapping channels chosen the substantiallunar surface in the minutes next to heating of the the LCROSS impacts. That data may possibly help scientists டு determine how much water was present at the time of impact. NASA
