ESA tracking station loses contact with Phobos-Grunt
The ESA tracking station that had made contact with Phobos-Grunt earlier this week failed repeatedly yesterday to re-establish contact.
An update on the efforts to save Phobos-Grunt

“The first pass was successful in that the spacecraft’s radio downlink was commanded to switch on and telemetry was received,” said Wolfgang Hell, ESA’s Service Manager for Phobos–Grunt. Telemetry typically includes information on the status and health of a spacecraft’s systems. “The signals received from Phobos–Grunt were much stronger than those initially received on 22 November, in part due to having better knowledge of the spacecraft’s orbital position.”
The second pass was short, and so was used only to uplink commands – no receipt of signal was expected. However, the following three passes in the early morning of 24 November proved to be more difficult: no signal was received from Phobos–Grunt.
ESA antenna contacts Phobos-Grunt again, this time downloading telemetry data
An ESA tracking station has once again contacted Phobos-Grunt, this time downloading telemetry data.
“We have again established contact with the Phobos-Grunt spacecraft, we obtained telemetry reports, they are being analyzed by our colleagues from the Lavochkin Research and Production Association,” ESA spokesman Rene Pischel said.

Russian space agency head says there is still a chance to save Phobos-Grunt
The head of the Russian space agency said yesterday that there is still a chance to save Phobos-Grunt.
“The probe is going to be in orbit until January, but in the first days of December the window will close” to re-programme it, he told Russian news agencies at Russia’s Baikonur cosmodrome in Kazakhstan.
He also said that the probe will not pose a threat, and will burn up in the atmosphere if it should fall to Earth.
Soyuz rocket successfully launches three astronauts into orbit
A Soyuz rocket has successfully launched three astronauts into orbit.
This is the first manned launch since the shuttles were retired, and the first Russian manned mission since the failure of a Soyuz rocket in August. If all goes well, the astronauts will dock with ISS in two days.
First manned Soyuz launch set for Sunday night
The first manned Soyuz launch since the launch failure in August is set for Sunday night.
Toxic Russian Mars probe aims for Earth
It now looks like the stranded and toxic Russian Mars probe, Phobos-Grunt, is likely aimed at Earth.
We are looking at an uncontrolled toxic reentry scenario. Phobos-Grunt . . . is fully-laden with unsymmetrical dimethylhydrazine and nitrogen tetroxide; that’s ten tons of fuel and oxidizer. The probe itself weighs-in at only three tons. . . . Phobos-Grunt’s batteries are draining and its orbit is degrading. It looks as if the probe will reenter later this month/early December. NORAD is putting a Nov. 26 reentry date on Phobos-Grunt.

“Overnight, several attempts were made to obtain telemetric information from the probe. They all ended with zero result,” Interfax quoted a source in the Russian space sector as saying. “The probability of saving the probe is very, very small,” added the source, who was not identified.
