For the past 138 years, since its discovery in 1867, Comet Tempel 1 has had distant but harmonious relations with the inhabitants of planet Earth. But on July 4, somewhere between Mars and Jupiter, NASA’s Deep Impact spacecraft blasted a gaping hole into the comet. The crash emitted the energy of 4.5 tons of TNT, releasing a tremendous plume of dust and gases.

“There is a comet up in the sky wondering, what in the heck just happened,” commented Charles Elachi, director of NASA’s Jet Propulsion Laboratory. In an astonishingly tricky mission, Deep Impact traveled 268 million miles over six months to wreak havoc on the comet. According to NASA scientist Don Yeomans, “We hit it just exactly where we wanted to.” More than 80 million people visited the NASA website in the 24 hours following the blast to witness the cosmic fireworks.
