If 2 FRIENDS(NASA and the Kitt Peak Observatory) come to you and say the aliens are true because we have some green blood would you believe them?
Yes it is a good example to show you not to believe anyone and anything.
Don't you think the fact that the other 2 Observatories didn't see anything

Impact of this size? It was a small impact. Please provide any statement by anyone (any scientist that is) that a brilliant flash was expected.
Do you reject the image of the hot spot left in the crater after the impact?
Will you reject all the data as it undergoes analysis and becomes available?

Earthbound observatories have reported capturing both impacts. But before crashing into the lunar surface itself, the LCROSS spacecraft's instrumentation successfully recorded close-up the details of the rocket stage impact, the resulting crater, and debris cloud. In the coming weeks, data from the challenging mission will be used to search for signs of water in the lunar material blasted from the surface.

It seems that no matter where the data comes from, some people will find a reason to dismiss it. Therefore those people who have a pre-conceived notion that the impact never occurred can never be convinced to believe otherwise.

A ten inch meteoroid slower than LCROSS yet the flash plainly visible from earth with a backyard telescope
"It was a space rock about 10 inches (25 cm) wide traveling 85,000 mph (38 km/s)," he says.
"On May 2, 2006, a meteoroid hit the Moon's Sea of Clouds (Mare Nubium) with 17 billion joules of kinetic energy—that's about the same as 4 tons of TNT,"
The energy associated with the LCROSS impact is about 6 billion Joules (1 Watt = 1 Joule per sec, so the energy of LCROSS is what you’d get from 100 million 60 Watt light bulbs in a second).

a) The moon has exterme gravity variations. Anything orbiting it will sooner or later crash into it. Landing would be the only other option, but landing has of course a higher delta v than crashing or orbiting (you need to decelerate) higher delta V = more propellant required = less payload or bigger craft = costs more money.
b) They crashed a Centaur rocket into it. The rocket that put LCROSS there in the first place. It was already there. It would have crashed anyway. NASA chose to crash it somewhere interesting, and watch while doing that, trying to squeeze a little extra bit of science out of it (Like any other space agency so far did that had something in moon orbit)
So: from a money perspective it was the smart thing to do.

The datastream ended on impact (obviously).

since these events do regularly occur, have
photographs been taken of natural impacts?
Here's an impact video of a 10-inch meteor hitting the moon from May, 2006. Note that they specify that the video was recorded using a 10-inch telescope.
-=Math people=-:
That event is reported as a 10-inch meteoriod colliding at 85,000 mph. The first LCROSS impact was supposed to be 4400 pounds at 5600mph. Can we get a comparitive estimate of impact energy? I realize we don't know the density of the 10-inch meteroid, but the article claims that its speed and dimensions were estimated from the brightness of the event. What I'd like to know is...if 10-inch object at 85,000mph is brightly and clearly visible from a 10-inch earthbound telescope, how unrealistic does it seem that a 4400 pound object impacting at 5600mph would not be visible from a 200-inch telescope.
Thank you.
