MOSCOW. Jan 26 (Interfax-AVN) - A commission investigating the malfunction and subsequent crash of the Russian Phobos-Grunt interplanetary station has finished its work and will present its findings to Federal Space Agency (Roscosmos) Chief Vladimir Popovkin on January 29, Roscosmos Deputy Chief Anatoly Shilov told journalists.
The U.S. has refused to help Russia probe the incident, he said.
"Roscosmos has sent an official proposal to the U.S. that it take part in the investigation, but they declined," Shilov said.
It was reported earlier that, among possible causes for the incident, the commission was analyzing the possibility that the probe could have been disabled by a U.S. radar station and could invite the U.S. to look into this together.
"This theory was analyzed, and it was examined using ground test beds," Shilov said.
He said he was unaware whether the U.S. radar theory was mentioned in the commission's final report.
The commission's report has been signed by its members, Shilov said. "When Roscosmos chief Vladimir Popovkin returns from Baikonur on Sunday, the commission's head, Yury Koptev, will submit the report to him," he said.
The causes of the Phobos-Grunt crash will be made public next week, he said.
