The visible camera image showing the ejecta plume at about 20 seconds after impact.
Data from the down-looking near-infrared spectrometer. The red curve shows how the spectra would look for a "grey" or "colorless" warm (230 C) dust cloud. The yellow areas indicate the water absorption bands.
Data from the ultraviolet/visible spectrometer taken shortly after impact showing emission lines (indicated by arrows). These emission lines are diagnostic of compounds in the vapor/debris cloud.
The water levels may be rising on the moon due to Global Warming. Send Algore up there on LCROSS 2 (it may take a Saturn V to get the lift capability for that job).
Awesome!!!!
NASA figures” if we can out-lie the muslim in chief, we can scam more money for our Buck Rogers schemes”.
Traveling as fast as a speeding bullet, the Centaur impacted the lunar surface
arrrrgggh!!
I hate that saying, it's utterly meaningless.
Muzzle Velocities (Handgun rounds)
a 50gr .25 Auto travels at 760 fps, or 518 mph
a 150 gr, .38 Special travels at 845 fps, or 576 mph
a 230gr, .45 ACP travels at 835 fps, or 569 mph.
and a 115 gr. 9mm JHP goes 1,225 fps, or 835 mphBut now, for Rifle Muzzle Velocities we have a little something more 'fitting':
a 130 gr. 270 Win goes at 3050 fps, or 2,080 mph
a 150 gr, 30-30 Win goes 2390 fps, or 1,630 mph
a 150 gr, .308 Win goes 2810 fps, or 1,916 mph
a 123 gr. FMJ, 7.62x39 goes 2,350 fps, or 1,602 mph
and a 55gr, .223 Rem travels at 3,240 fps, or 2,209 mph
So really. What does, 'as fast as a speeding bullet' mean -- nothing. We have sub-sonic handgun rounds to rifle bullets approaching Mach 3. But for a Spacecraft's 'speed'? ... Whoopee! It was a cool saying for Superman and that's about it.
Oh and a 40 gr, .22LR goes 1,255 fps, or 856 mph. (Mach 1.125)
And those *evil* Pellet Rifles with 1,000 Muz Vel, that little pellet is going 682 mph, or Mach .9, now that is cool. (No wonder Chicago outlawed those back in the '50's.) (/s)
