Spacecraft racing to slam into a cometThe Philadelphia Inquirer
June 30, 2005
Eighty-three million miles from here, a NASA spacecraft is closing in for the first real-life attack on a heavenly body - a comet called Tempel-1. On Monday, the spacecraft will send an 800-pound projectile smashing into the comet to expose whatever is inside.
The Hubble and two other space-based telescopes and countless observatories on the ground will be focused on tiny Tempel-1 during the impact, planned for 1:52 a.m. Philadelphia time.
"We don't know what's going to happen," said Jack Brandt, a comet expert from the University of New Mexico. Most likely a huge crater will form, but as a long shot, scientists say the impact could blow the whole thing to bits.
