The Philae probe is alive and well a day after the first successful spacecraft landing on a comet, but scientists are still trying to figure out exactly where it is on its new home.

Philae reached an altitude of about six tenths of a mile at the top of the arc -- more than 3,000 feet if the estimates are correct -- landing again about six-tenths of a mile away.

Philae made history on Nov. 12 when it landed on the speeding comet, marking the culmination of a 10-year, 4-billion-mile journey to the comet by hitching a ride with the Rosetta spacecraft.
