Roscosmos To Investigate ArabSat Orbit Error

Roscosmos, the Russian space agency, has formed a state commission to investigate the anomaly last week that caused a Proton Breeze M vehicle to place the ArabSat 4A satellite into an incorrect orbit. The commission, led by Victor Remishevsky, deputy director of Roscosmos, plans to complete the investigation by March 30.

The launch on Wednesday was carried out under the auspices of International Launch Services, a joint venture of Lockheed Martin Corp. and Khrunichev State Research and Production Space Center.

ILS said in a statement Friday it is forming a Failure Review Oversight Board independently of the Russian commission. The board will be chaired by Eric Laursen, ILS vice president and chief engineer. The board will "independently review the methods, conclusions and corrective action recommendations of the Russian state commission investigation" and report on the findings, the company said.

"All oversight board activities will be subject to relevant U.S. government regulations," the ILS statement added.

Deputy chairmen of the Roscosmos commission will be Yuri Bakhvalov, first deputy general designer from Khrunichev, which built the Proton vehicle and the Breeze M upper stage, and Alexander Chulkov, director of payload deployment systems at the space agency.

When astronauts visit the Hubble Space Telescope in October 2008 for its final servicing mission, they will be facing a task that has no precedence – performing on-orbit ‘surgery’ on two ailing science instruments that reside inside the telescope – the Space Telescope Imaging Spectrograph (STIS) and the Advanced Camera for Surveys (ACS).

Europe’s first satellite-borne rubidium clocks have been in orbit for over a year. There is good news for the building of the Galileo system: the results obtained from GIOVE-A’s first year of operations show performance that is largely in line with the specifications.
GIOVE-A transmits first navigation message
Earlier this week, GIOVE-A successfully transmitted its first navigation message, containing the information needed by user receivers to calculate their position. Prior to reaching this milestone, the satellite had been broadcasting only the data needed for measuring the receiver-to-satellite distance.
GIOVE-A laser ranging campaign successful
Fourteen laser ranging stations participated in a campaign to track ESA's GIOVE-A satellite during the spring and summer of 2006, providing invaluable data for the characterisation of the satellite's on-board clock. The campaign was coordinated by the International Laser Ranging Service (ILRS) and the GIOVE Processing Centre at ESA-ESTEC.
