An asteroid nearing Mars will not crash into the planet later this month, scientists said Wednesday. New observations of the Mars-bound Asteroid 2007 WD5 have allowed astronomers to refine their predictions for the space rock's position during its red planet rendezvous on Jan. 30, according an update by NASA's Near-Earth Object (NEO) program office. "As a result, the impact probability has dropped dramatically, to approximately 0.01 percent or 1-in-10,000 odds, effectively...

An impact with Mars by an approaching asteroid is now believed by scientists to be less likely than before. New estimates of the asteroid's orbit were made using observations from a telescope at the Calar Alto Observatory in Spain, according to the Near-Earth Object Program at NASA's Jet Propulsion Laboratory. The probability of impact was reduced to 2.5 percent reported in a January 8 update posted on the NEO website. The distance it is believed to miss Mars by is about 18,600 miles. Dubbed...

The possibility of an asteroid walloping the planet Mars this month is whetting the appetites of Earth-bound scientists, even as they further refine the space rock's trajectory. The space rock in question — Asteroid 2007 WD5 — is similar in size to the object that carved Meteor Crater into northern Arizona some 50,000 years ago and is approaching Mars at about 30,000 miles per hour (48,280 kph). Whether the asteroid will actually hit Mars or not is still...

LOS ANGELES -- The chance of a football field-sized asteroid plowing into Mars next month has been increased to 4 percent, scientists said Friday after analyzing archival data. Though still a long shot, some researchers are hoping for a cosmic smash. "I think it'll be cool," said Don Yeomans, who heads the Near-Earth Object Program at NASA's Jet Propulsion Laboratory. "Usually when an asteroid is headed toward Earth, I'm not rooting for an impact." The space rock, known as the nondescript...

WASHINGTON - Astronomers funded by NASA are monitoring the trajectory of an asteroid estimated to be 50 meters (164 feet) wide that is expected to cross Mars' orbital path early next year. Observations provided by the astronomers and analyzed by NASA's Near-Earth Object Office at the Jet Propulsion Laboratory in Pasadena, Calif., indicate the object may pass within 30,000 miles of Mars at about 6 a.m. EST (3 a.m. PST) on Jan. 30, 2008. "Right now asteroid 2007 WD5 is about half-way between...

By ALICIA CHANG LOS ANGELES - Mars could be in for an asteroid hit. A newly discovered hunk of space rock has a 1 in 75 chance of slamming into the Red Planet on Jan. 30, scientists said Thursday. "These odds are extremely unusual. We frequently work with really long odds when we track ... threatening asteroids," said Steve Chesley, an astronomer with the Near Earth Object Program at NASA's Jet Propulsion Laboratory. The asteroid, known as 2007 WD5, was discovered in late November and is...

LOS ANGELES -- Mars is ready for another close-up. For the second time in nearly 60,000 years, the Red Planet will swing unusually close to Earth this weekend, appearing as a yellow twinkle in the night sky. Mars' latest rendezvous will not match its record-breaking approach to Earth in 2003, when it hovered from 35 million miles away. But more skygazers this time around can glimpse the fourth rock from the sun because it will glow above the horizon. "This is the best we're going to see...
