Photos: Spectacular sunset launch of asteroid mission

A Mars orbiter developed by the United Arab Emirates in partnership with U.S. scientists has been mounted on top of a Japanese H-2A rocket and its battery charged for liftoff Tuesday from the Tanegashima Space Center.

NASA unveiled an ambitious program Friday to commercialize low-Earth orbit, making way for product development and even advertising aboard the International Space Station, month-long visits by company astronauts starting as early as next year and use of a station docking port for privately financed research-and-development modules.

The launch of a Japanese H-2B rocket was called off Tuesday after a fire broke out on the launch pad a few hours before liftoff. A new target launch date has not been confirmed. The mission will carry an HTV cargo ship into orbit on a resupply run to the International Space Station.
