NASA sending hammer to space
Everybody cross your fingers:
'If all goes well, an 820-pound copper "hammer" the size of a bathtub will separate from its mother ship and, 24 hours later, smash into the comet's icy nucleus at about 23,000 mph.
The high-speed impact will wallop the pickle-shaped comet with energy equivalent to 4.8 tons of TNT, said Michael A'Hearn, a University of Maryland astronomer and principal investigator on the $311 million mission.
Nobody's sure what will happen next.' (The Arizona Republic article via FARK)
