NASA is preparing to launch the Lunar Crater Observation and Sensing Satellite, which will fly a Centaur rocket booster into the moon, triggering a six-mile-high explosion that scientists hope will confirm whether water is frozen in the perpetual darkness of craters near the moon's south pole. If the spacecraft launches on schedule at 12:51 p.m. Wednesday, it will hit the moon in the early morning hours of October 8 after an 86-day Lunar Gravity-Assist, Lunar Return Orbit that will allow the spacecraft time to complete its two-month commissioning phase and conduct nearly a month of science data collection of polar crater measurements before colliding with the moon just 10 minutes behind the Centaur.
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°. The resulting impact craters will be ~28m in diameter by ~5m deep (Centaur) and ~18m in diameter by 3.5m deep (Shepherding Spacecraft). The ejected mass from these craters is shown in Figure 2. Analysis to date has shown LCROSS will create a significantly larger crater than Lunar Prospector (LP) that hit the Moon at 1.7 km/s with a 158 kg impactor at a glancing angle of 6°. Temperatures reached will be insufficient to vaporize most (~90%) of the material, though is expected to create a very brief visible flash that will last < 100ms which will be measured by the S-S/C photometer instrument. Most of the ejecta will be thrown upward at a velocity of >250 m/sec, and will contain water in its solid state, as water ice mixed with the dust (refractory minerals).

so that they can fly rockets into the fucking moon
blorange
water and ice sometimes are under things
like dust and rocks
'door hinge'
Show that Moon, who it's fucking with.
:^:
What about water now?
Man, we're blowing up the moon! Whatever excuse we use for doing so needs to be quickly forgotten and never mentioned again.

i c
We're starting a war with the Moon
to the naked eye yes
ughhh
edit tteefs
Coran Attack!
is was awesome because most of the episode was really just a history lesson about moon origin theories that have popped up over the years
I mean, I assume meters
but I can't really tell
also, 28m is not very big for a 6 mile high debris blast
Did they happen to say when people realized it was round?
Because man, living in a time where you think it's this crazy ass disk in the air...

did you get your name from usagi yojimbo
it's been a while but I don't think they did that, no
I've never thought to read the moon's wiki page. Hm...I bet it's long as all hell.

I'm assuming its meters because they're using kilograms, so SI units
nope
Nice going, moon.
and thanks wikipedia.
