Nasa probes begin studying the moon

2012-03-07 10:05

Los Angeles - Twin Nasa probes in orbit around the moon have begun mapping the lunar gravity field in hopes of figuring out why Earth's only natural satellite is shaped the way it is.

The campaign kicked off late on Tuesday, two months after the spacecraft arrived back-to-back at the moon over the New Year's weekend.

Despite numerous missions to the moon, scientists still don't know why the far side of the moon is more mountainous than the side that always faces Earth.

The $496m mission is officially called the Gravity Recovery And Interior Laboratory. It was launched last September from Florida.

Probes entered orbit around the moon in January but couldn't start collecting data right away because they had to tweak their positions until they were 56km above the surface.

    These guys claim they've walked on the moon. Now they send probes to orbit 56km above the surface to collect data why the far side is more mountainous. Why not send people to the surface again to do these tests or is this to difficult. Makes you wonder if there really is an American flag on the moon.......

      Hannes, Hannes, Hannes... Your stupidity is only outclassed by your ignorance.
