VideoHow OSIRIS-REx will snag a sample from asteroid Bennu
Mars rovers go through seven minutes of terror when they plunge into the Martian atmosphere at hypersonic speed. NASA's OSIRIS-REx spacecraft will take a more glacial approach to its asteroid target Tuesday, and the event will be more akin to four-and-a-half hours of mild anxiety for ground teams, according to the mission's operations manager.

VideoLive coverage: Launch of Emirates Mars Mission rescheduled for Sunday
The launch of a Japanese H-2A rocket with the Emirates Mars Mission, a Mars orbiter developed in partnership between Emirati and U.S. scientists, was delayed Tuesday due to poor weather at the H-2A's launch site on Tanegashima Island in southern Japan. Officials later announced that liftoff would not occur Thursday, again citing bad weather at the launch site. A new launch attempt is scheduled for Sunday, weather permitting.
