NASA to bomb the Moon on Friday morning, watch from Earth

I got a C in Physics. I guess my question was more in relation to just how big of an impact this NASA thingie is supposed to make.

Well I will give you a hint: even with all the bombs we have it would take one seriously massive bomb to blow the moon out of orbit lol. Its not exactly a pebble floating in space that will move if you blow on it lol.
 
I think they're just trying to get rid of the alien base evidence on the dark side of the moon before China or India find it. ;-)

I think the moon gets hit by bigger stuff all the time (for what "all the time" is worth on a geological scale, at least ;)); that's why there are so many craters, unless I'm being presumptuous (I haven't done any real research on it). :D

What effect will the impact have on the Moon?

Countless objects have hit the Moon since its formation (in fact, the Moon’s formation was quite possibly the product of a very large impact to the Earth). Most of the large craters one sees on the Moon resulted from large asteroid or comet impacts early in the history of the solar system; however, numerous impacts by much smaller objects continue even today. These smaller objects range in size from smaller than a grain of sand to a basketball. Most of the shooting stars one sees at night are indeed small grains to rock-sized fragments entering the Earth’s atmosphere. If they are hitting the Earth’s atmosphere, you can bet some are also hitting the Moon! (which has no atmosphere to burn them up or slow them before they reach the surface). While these objects are small, due to their high velocity (~40 km per sec), even these relatively small objects pack a considerable punch! 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 10 kg (about 22 lbs) meteorite would impact with about 8 billion Joules of energy. There are probably several of these size objects striking the Moon every few months (some have recently been imaged by small ground-based telescopes using high-speed-film cameras). So, in short, the Moon has been, and continues to be, pummeled by objects of all sizes over the last 3.9 billion years, many of them having energies many, many times greater than that of the LCROSS impact.

The LCROSS impact will not be noticed by the Moon and only noticed by those on Earth with telescopes trained on the impact site. What makes the LCROSS impact special, compared to the ongoing, natural barrage, is that we control the LCROSS impact to occur at a precise place and time. allowing us to sample a specific piece of lunar real estate and be in position to monitor it.

Nuclear weapons are far more destructive than any conventional (non-nuclear) weapon. They are often called atomic bombs or hydrogen bombs. The energy released by nuclear weapons is measured in tons, kilotons (thousands of tons), or megatons (millons of tons) of TNT. In international standard units (SI), one ton of TNT is equal to 4.184 × 109 joule (J).

Nuclear weapons have a large variety of energy yields. The first detonated on July 16, 1945 near Alamogordo, New Mexico, had a yield of about 19 kilotons or 80 terajoules (1 TJ = 1012 J). The two bombs that were dropped on the Japanese cities Hiroshima and Nagasaki during World War II were comparable in size: 15 and 20 kilotons or 63 and 84 terajoules, respectively.

Thank you. That's the sort of information I was looking for. Minus the smartass remarks.
 
why the frownie? they have been planning this for a long time, big deal, it's just the moon, no moon bunnies are going to be hurt.
 
NASA running 5 minutes late on impact? I am wondering if this is an overt attempt to take the moon further out into orbit, or see the effect such an impact actually has on the orbit and what it would take to actually effect it, while playing the we are looking for water card? I went outside looked at the moon and it is still there... who in the hell knows what NASA is really up too?

That was kind of anti-climatic.

Guess we will have plume shots from earth observatories in a couple of hours and maybe preliminary data. Apparently the thermal signature was a good sign for water being there.

I thought we would have sophisticated enough technology to use radar and satellite to find... water.

Lunar tides will be altered. This will cause a change in the foor chain, as many sea animals depend on the tide for food. This will directly affect humans, as we are at the top of the food chain. Earthquakes, Tsunamis, floods, a butterfly flaps it's wings and changes the weather on the other side of the earth...What does NASA think blasting a two ton bomb at 5,600mph on the surface of the moon will do, detect water that will vaporize as soon as the bomb brings the temperature to the boiling point? What water? Drop a program which costs $125,000 a year, just because it will tell us how far the moon has been knocked out of it's orbit? Believe this, there is NO WAY to alter the effects after the fact. Nobody has EVER done this before, how do they know the will do no damage? I pray.

what is our vote for? says:
I am lost here, who in the world decided that the government could just piss all our money away on this crap. 10.8% unemployment in the U.S. oh but we have 500 million to blow up the moon. The myan calendar is wrong people, that prediction was if we sat still and didn't touch anything.... we are to stupid to do that so let’s speed it up! Fanny and Freddy...good idea...tripling the deficit...better...sending jobs to china...B-E-A-utiful...blowing up the moon...how does the credit card companies say it?....Priceless! For everyone else there is communism! Who decided that the moon belonged to the U.S. anyway…I mean the world can’t fart without us taking a whiff so when does the rest of the world get to decide that we are idiots?

I thought this was remarkably insightful...
