On Oct. 9 at 4:30 a.m., the Ames team will send that 2-ton rocket crashing precisely into the target to send up a cloud of dust and debris more than 6 miles high.

There, acting as what the Ames team calls its "shepherding spacecraft," LCROSS will guide an empty Centaur rocket weighing two tons toward its target. The rocket will crash into the crater at 5,600 mph, creating a new crater - perhaps as large as 5 miles wide.

How is that not destructive? You can be destructive to the moon without completely destroying it. You can damage something without obliterating it.
Yes, something did. They had a fuel problem.Nothing went wrong. [
NASA’s LCROSS lunar probe used up most of its fuel supply over the weekend when it was hit by a control problem with its Inertial Reference Unit, causing excess thruster firing. Initial reports were that about 70 percent of the fuel was used up.

The entire purpose of the destructive mission is to find proof of water. This proof has already been found.The fact that other scientific organizations made progress is in no way a bad thing. Also, your flippant references to "blowing crap up" shows a great deal of ignorance. Spectral analysis of a high energy impact can yield a wealth of information with a degree of certainty that is very difficult to match.
What is the primary mission goal of LCROSS?
There is evidence from previous missions for enhanced hydrogen deposits at the poles of the Moon. Due to limitations in the data sets that measured this hydrogen, we still do not know the form of the hydrogen, that is, is it in the form of water (H2O) or some other hydrogen-bearing compound, such has hydrated minerals or hydrocarbons.
LCROSS - FAQ
India has already done this and we were partnered with them while they did it!
Three different spacecraft—India’s Chandrayaan-1, and NASA’s Cassini and Deep Impact—detected trace amounts of water molecules (H20) and hydroxyl (OH) while mapping the moon’s surface. Researchers estimated that 32 ounces of water can be found for every ton of the moon’s top layer, meaning that the moon is still drier than any desert on Earth.
Proof of Water on the Moon: What Does It Mean for the Future of Space Exploration?
Since the mission has already been accomplished there is no need to blow up anything, create any new deeper craters on the moon, pollute the moon, etc. with this mission.
I haven't found anything. And why wouldn't he address the nation on this? The fact that India in partnership with us Americans has proven there is water on the moon is a significant find itself. Since he's going on late night tv this is just the sort of thing that might warrant a mention.I seriously doubt that Obama has never talked about LCROSS at all. It is not a major mission, and I am completely unsurprised that it isn't a major talking point, but I'm sure he has discussed it whether or not it made CNN's front page. I don't see the need for him to address the nation at all - what would he say? As you've stated, the Indians have already announced the presence of water.
Right a rocket isn't a weapon and launching it right into a moon to create a huge explosion that alters the land isn't destructive.This is in no way a weapon
No because NASA has made much of how this impact, this rocket, will be launched at a much steeper impact angle as opposed to the Jap. probe.When the Eagle landed was that "modifying a celestial body?" How about when any of the dozens of probes in this list impacted? How
about when the Japanese probe impacted?
Previously you stated that the Japanese probe was okay but this mission is not. I looked into it, and the Japanese probe was in fact bigger than the Centaur (2,300 kg vs 2,900 kg). Does this change your opinion at all?
Kaguya was flying at a horizontal velocity of about 4,000 mph, but the spacecraft struck the moon at an angle of just 1 degree. The grazing impact was expected to diminish the crater size and dust cloud caused by the crash.

The goal in this mission is the exact OPPOSITE of going for a smaller crater. The objective is to create a huge disturbance, large plume, and the angle is 70 degrees vs 1 degree.
The lunar impacts of the 2000 kg upper stage and the 700 kg S-S/C will take place at a velocity of 2.5 km/sec and at an angle of 75°
LCROSS - Mission Rationale
The way it is being launched into the moon at a steep angle is very different from it just crash landing. It is akin to blowing a hunk out of the moon.Are you under the impression that there is an explosive warhead being launched into the moon? Your usage of the term rocket and the phrase "blowing crap up" seems to suggest that. All that's impacting the moon is the empty upper stage. In any other mission this piece of hardware would just be set adrift (to eventually impact a celestial body)
See above.Out of all of that there are really two things I'd like an answer to. Are you under the impression that there is an explosive warhead being launched into the moon? Does the fact that the Japanese probe, which you previously stated you were okay with, was bigger than the LCROSS impactor change your opinion at all?
Jap probe was intentionally crash landed at an angle that would cause the smallest crater/plume/damage possible.
This rocked will be launched at the moon like a missile at a steep angle designed to go to deep, create a huge crater, and a visible dust plume.
Two completely different things.

It isn't a weapon. No one lives on the moon and there are no structures to destroy. Furthermore, the rocket is consumed during the explosion, so it's not like we can use this rocket as a base with which to attack future moon settlements or earth nations.Originally Posted by talloulou
If I'm not mistaken, that just happened a few days ago. This rocket was launched in June. What exactly do you want them to do...call off an expensive mission that's already in progress, just because someone beat them to the punch by a few days? If nothing else, it will provide independent confirmation to the Indians' claim, which is always good.Originally Posted by talloulou

I can't. This is important.
