It's a long way for a rock to travel, but scientists confirm that several meteorites that plunged into southern Morocco last summer are actually from Mars. Meteorites do fall on the Earth, but debris from Mars has only made it to Earth on four previous occasions, according to AP. The Martian meteorite fall is the first since 1962.

The U.S. Chamber of Commerce was infiltrated by computer hackers last year, and the Wall Street Journal reports the organization blames saboteurs in China. The attacks occurred in May 2010; the hacking was so "sophisticated" that the infiltrators accessed all of the Chamber's data, including information about the group's three million members.

Boeing is leasing an old shuttle hangar from the Kennedy Space Center to construct the Crew Space Transportation-100 vehicle, or the CST.
