In a bold attempt to revive its long-dormant planetary exploration program, Russia is scheduled to launch a new, technologically sophisticated spacecraft this week to gather soil samples from a Martian moon and bring them back to Earth for analysis. Back in the early 1970's, the Soviet Union, after losing the race to land humans on the Moon, brought back lunar soil samples with robotic devices. It also became the first nation to put robotic devices on Venus and Mars. Such pioneering ventures ended after the Soviet Union disintegrated and the economy soured, depriving the space agency of funds. But now Russia is poised to launch a spacecraft that will land on Phobos, a 17-mile-long rock that is the larger of two Martian moons. It will conduct studies there, extract surface materials, put them in a container, and return them to Earth in a small capsule, all in less than three years. Along the way it will drop off a Chinese satellite that will orbit Mars to study its surface, atmosphere, magnetic fields and other processes. [ABSTRACT FROM AUTHOR]

It has been driving on and off for more than seven years, but now it has reached its new destination. Opportunity, a small exploratory rover that landed on Mars in 2004, has trundled to a crater called Endeavour. And the first rock it looked at has already opened a new chapter in the study of Mars, NASA scientists said Thursday. On a telephone news conference, mission scientists giddily described that rock: full of zinc and bromine, elements that, at least for rocks on Earth, would be suggestive of geology formed with heat and water.
