Scientists raise odds that asteroid might hit Mars

Winston-Salem Journal

LOS ANGELES - The chance of a asteroid the size of a football field crashing into Mars next month has been raised to 4 percent, scientists said yesterday after analyzing archival data.

The asteroid, known as 2007 WD5, was discovered in late November by the NASA-financed Catalina Sky Survey in Arizona. Based on the latest information available, scientists said last week that there was a 1-in-75 chance the asteroid could hit Mars on Jan. 30.

The odds were increased to 1-in-25 this week after a Ph.D. student pored through the archives and plotted the asteroid’s motions before its official discovery.
