Moon Bombing

[MRX]

For those interested in space stuff NASA are going to bomb the moon today at 12.30 (i think this is the UK time). By bombing it and using their Lunar CRater Observing and Sensing Satellite (LCROSS) they plan to look for the presence of water.

Mission Overview

 

Earth’s closest neighbor is holding a secret. In 1999, hints of that secret were revealed in the form of concentrated hydrogen signatures detected in permanently shadowed craters at the lunar poles by NASA’s Lunar Prospector. These readings may be an indication of lunar water and could have far-reaching implications as humans expand exploration past low-Earth orbit. The Lunar CRater Observing and Sensing Satellite (LCROSS) mission is seeking a definitive answer.

 

In April 2006, NASA selected the LCROSS proposal for a low-cost, fast-track companion mission to the Lunar Reconnaissance Orbiter (LRO). The main LCROSS mission objective is to confirm the presence or absence of water ice in a permanently shadowed crater near a lunar polar region.

 

LCROSS launched with the Lunar Reconnaissance Orbiter (LRO) aboard an Atlas V rocket from Cape Canaveral, Fla., on June 18, 2009 at 2:32 p.m. PDT. The LCROSS shepherding spacecraft and the Atlas V’s Centaur upper stage rocket executed a fly-by of the moon on June 23, 2009 (LCROSS lunar swingby video stream coverage) and entered into an elongated Earth orbit to position LCROSS for impact on a lunar pole. On final approach, the shepherding spacecraft and Centaur will separate. The Centaur will act as a heavy impactor to create a debris plume that will rise above the lunar surface. Projected impact at the lunar South Pole is currently: Oct 9, 2009 at 4:30 a.m. PDT. Following four minutes behind, the shepherding spacecraft will fly through the debris plume, collecting and relaying data back to Earth before impacting the lunar surface and creating a second debris plume.

 

The debris plumes are expected to be visible from Earth- and space-based telescopes 10-to-12 inches and larger.

 

The LCROSS science payload consists of two near-infrared spectrometers, a visible light spectrometer, two mid-infrared cameras, two near-infrared cameras, a visible camera and a visible radiometer. The LCROSS instruments were selected to provide mission scientists with multiple complimentary views of the debris plume created by the Centaur impact.

 

As the ejecta rises above the target crater’s rim and is exposed to sunlight, any water-ice, hydrocarbons or organics will vaporize and break down into their basic components. These components primarily will be monitored by the visible and infrared spectrometers. The near-infrared and mid-infrared cameras will determine the total amount and distribution of water in the debris plume. The spacecraft’s visible camera will track the impact location and the behavior of the debris plume while the visible radiometer will measure the flash created by the Centaur impact.

 

NASA’s Ames Research Center, Moffett Field, Calif., is overseeing the development of the LCROSS mission with its spacecraft and integration partner, Northrop Grumman, Redondo Beach, Calif. LCROSS is a fast-paced, low-cost, mission that will leverage some existing NASA systems, commercial-off-the-shelf components, the spacecraft expertise of Northrop Grumman and experience gained during the Lunar Prospector Mission in 1999. Ames is managing the mission, conducting mission operations, and developing the payload instruments, while Northrop Grumman designed and is building the spacecraft for this innovative mission. Ames mission scientists will spearhead the data analysis.

What happens if it just blows up? Won't someone think of the werewolves!!!!!!!!!

[MrRalphMan]

I would have thought they would be relieved.. But what about TMITM???

[China Man]

lol, crude way of hit it and see if it works

red shirt : "high-5 dude...we just bombed the mother-fecking moon!!"

black shirt : "high-5?...no way..I've been observing you playing pocket billiards for the past 2 hours under your desk!"

Was anyone else disappointed after watching it? I was expecting some large cloud of dust or a flash as predicted....Nadda, zip, niete.

[Branners]

so, any friendly fire incidents from this unwarranted bombing of a peaceful and as yet unfriendly neighbour?

or a flash as predicted....Nadda, zip, niete.

 

I'm still trying to figure out why any form of flash or explosion would have happened, I doubt they'd have sent it in with excess fuel on board, and there's no oxygen/air either to help cause one?

 

Not ranting, I've just heard a few people say it wasn't as good as there was no 'bang'? Should they have got Hollywood involved, like with the moon landings?

[Miguel]

Some CGI would've been nice. Maybe Arnie throwing a grenade in while shouting "fire in the hole" would have topped it off.

 

On a serious note, I would have thought that much metal impacting at that speed would have flashed up on the infared camera at least. That much energy would surely dissipate as heat? Even in the low temps of space. It was NASA themselves that made these predictions

That's a fair point

We all know there is no moon and the original landings never happened, I guess they just didn't spend enough on effects this time around.

Im surprised that no friendly fire accurd with it being americans and all.
