More attempts have been made by the European Space Agency (Esa) to contact the stricken Russian probe Phobos-Grunt - with partial success. Communication with the craft as it passed over Australia was achieved again on Thursday, but not all of the commands prompted a response. Read more
Contact Restored with Russia's Lost Mars Moon Mission
Scientists have picked up a signal from Russia's Phobos-Grunt spacecraft, the European Space Agency said Wednesday. The ESA reported that its tracking station in Perth, Australia, established contact with Phobos-Grunt on Tuesday at 20.25 UT. Read more
Contact has finally been made with Russia's troubled Mars mission, says the European Space Agency (Esa). The agency reports that its tracking station in Perth, Australia, picked up a signal from the Phobos-Grunt probe. Read more
ESA tracking station establishes contact with Russia's Phobos Mars mission
On Tuesday, 22 November at 20:25 UT, ESA's tracking station at Perth, Australia, established contact with Russia's Phobos-Grunt spacecraft. This was the first signal received on Earth since the Mars mission was launched on 8 November. ESA teams are working closely with engineers in Russia to determine how best to maintain communication with the spacecraft. Source
The Russian space agency has conceded there is now little chance of reviving its Mars mission, Phobos-Grunt. The probe has been stuck circling the Earth since its launch on 9 November, unable to fire the engine that would take it on to the Red Planet. Read more
Russian experts baffled by probe's erratic behaviour
Russian Federal Space Agency experts are puzzled by the rising orbit of the Phobos-Grunt unmanned Mars probe, Roscosmos deputy head Vitaly Davydov said on Tuesday. He suggested that the spacecraft's control system might still be functional or there could have been a fuel leak, causing its orbit to rise. A Russian expert earlier said one reason for the spacecraft's unexpected behaviour could be the aerodynamic resistance of its solar batteries acting as wings and pushing it up. According to another industry expert, Phobos-Grunt will not fall to Earth until mid-March because of its rising orbit. Read more
The plan was to have the probe, called Phobos Grunt, begin its journey in low Earth orbit before setting off towards Mars. That's where the plan has gone awry. Phobos Grunt is stuck in low Earth orbit and the rockets designed to send it on its way haven't fired. Read more
