The LCROSS has just impacted the moon and now there is a dust plum streaming out from the surface. The hope is that now scientists will observe water/ice in the cloud that has been thrown up in the air. If this proves to be true then it could have huge benefits for any future human landing on the moon as the presence of water could greatly reduce the cost of any long term missions.
So far there was no big dust cloud as what might have been thought when it hit the Moon however this is actually what scientist are hoping for as this means that there would be more dust thrown up to sample.
UPDATE: Here is a photo of the impact that has now been released.
Below are some of the photos just before it hit the moon…
This was the last visible light photo of Moon from LCROSS
