Astronomers Find Oldest Known Asteroids

Researchers from the University of Maryland have recently discovered three asteroids that appear to be roughly 4.55 billion years old, dating back to the formation of the Solar System. The scientists say that the asteroids have survived relatively unchanged since that time, and make good candidates for future space missions. "'The fall of the Allende meteorite in 1969 initiated a revolution in the study of the early Solar System,' said Tim McCoy, curator of the national meteorite collection at the Smithsonian's National Museum of Natural History. 'I find it amazing that it took us nearly 40 years to collect spectra of these [CAI-rich] objects and that those spectra would now initiate another revolution, pointing us to the asteroids that record this earliest stage in the history of our Solar System.

The Oldest Asteroids

Stellar Evolution Summary (Mar 25, 2008): Scientists have discovered three asteroids that appear to be among the oldest objects in the Solar System. Studying these asteroids could yield important clues about the origin and evolution of the planets.

Canada To Launch First Space Mission To Hunt Asteroids

Canada will launch a suitcase-sized satellite in 2009 to spot potentially dangerous asteroids near Earth's orbit. It will be the first space mission devoted to hunting asteroids and may help find ones that are difficult to spot from the ground.

Canada to launch first-ever space mission to search for asteroids

Canada is preparing to launch the first space mission ever to search for asteroids between Earth and the sun -- the type of asteroid most likely to slam into our planet. Fittingly for this country, the Near Earth Object Surveillance Satellite is not a Hubble-sized monster. It is a 60-kilogram micro-satellite, costing a mere $10-million yet able to deliver science results never seen before. NEOSSat will search for asteroids that are closer to the sun than Earth. These are nearly impossible to see from our planet's surface -- there is too much atmosphere and sunshine -- but easier to spot from space. The suitcase-sized satellite is expected to launch in two years. "This is the first space-based asteroid-searching telescope, period. Why shouldn't Canada be the leader in a field? And it happens in this case, we are," said Alan Hildebrand of t
