Mission to Martian moon stuck in Earth orbit

MOSCOW?? Russia's bid for its first interplanetary mission in 15 years went awry on Wednesday when an unmanned spacecraft failed to take the proper course toward Mars after its launch, space officials said.

Russian space agency chief Vladimir Popovkin said an engine failed to fire on the Phobos-Grunt probe after it reached Earth orbit, Interfax reported. The problem could doom the mission to bring back a soil sample from the Martian moon Phobos.

"The engine did not fire, neither the first nor the second burn occurred. This means that the craft was unable to find its bearings by the stars," Interfax quoted Popovkin as saying at Russia's Baikonur Cosmodrome in Kazakhstan.

In a forum on the mission's official website, Anton Ledkov of the Russian Space Research Institute said there was no telemetry from the craft. But Popovkin said officials were in contact with the probe, which remained in Earth orbit, and had three days to set it on course before the batteries run out.

Failure of the Phobos-Grunt mission would be a big blow to the pride and prospects of Russia's space agency, which was crimped by budget constraints and a brain drain following the 1991 Soviet collapse.

"They say there is hope to reset it. Apparently it's a problem with the programming, but there is very little time," the lead mission scientist, Alexander Zakharov of the Space Research Institute, told Reuters. "I feel grief. It's very sad that this is how it all worked out, but this is a consequence of our lack of people after such a big interval. ... Many young people worked on this. There is a lack of experience, we are working almost from scratch."

Haunted by failures
The $163 million probe blasted off at 12:16 a.m. Moscow time from the Baikonur launch pad on a Zenit 2SB rocket, starting what is meant to be a three-year trip to Phobos and back.

It was an undertaking haunted by past failures, and has become a test of the Russian space industry. If successful, its long journey would be the first Soviet or Russian deep-space probe to Mars to fulfill its mission completely.

Russian scientists have dreamed of probing the Red Planet's potato-shaped satellite Phobos, a mere 22 kilometers (13 miles) across, since the 1960s heyday of pioneering Soviet forays into space. But two Phobos missions sent up in 1988 failed, one going silent within meters of the surface. In 1996, another unmanned Russian craft bound for Mars broke up in the atmosphere after a botched launch.

"We have always been very unlucky with Mars," Zakharov said.

Moscow's last successful missions beyond Earth orbit, Vega 1 and 2, probed Venus and Halley's Comet in the mid-1980s.

Russia continues to ferry astronauts to the International Space Station, but a series of failed unmanned launches this year has underscored the fragility of its space program.

Shedding light on origins
Dust from Phobos, scientists say, could shed light on the genesis of the solar system, while data collected in its orbit might help solve enduring mysteries such as whether Earth's neighbor has ever supported life.

The plan is for Phobos-Grunt to reach Mars next year, touch down on the larger of Mars' two tiny moons in 2013, collect a sample from the surface and fly back to Earth in 2014.

Hitching a ride is China's first interplanetary spacecraft, the tiny 115-kilogram (250-pound) Yinghuo 1, which is to work in orbit with Phobos-Grunt over a year to study Mars' atmosphere.

Phobos-Grunt is also carrying vials of Earth bacteria suited to extreme environments, plant seeds and tiny invertebrate animals known as water bears to see if they can survive in space.

It is meant to be the first time microbes carried by a spacecraft spend years in space and go beyond the protective bubble of Earth's magnetic field, testing part of a theory that life may have migrated between planets inside meteorites.
