Tråden om Phobos-grunt

“We don’t want to accuse anybody, but there are very powerful devices that can influence spacecraft now,” Mr. Popovkin said in the interview. “The possibility they were used cannot be ruled out.”

Mr. Popovkin’s remarks to the newspaper Izvestia were the first high-level suggestion of nefarious interference. A retired commander of Russia’s missile warning system had speculated in November that strong radar signals from installations in Alaska might have damaged the spacecraft.

Mr. Popovkin did not directly implicate the United States in the interview. But he said “the frequent failure of our space launches, which occur at a time when they are flying over the part of Earth not visible from Russia, where we do not see the spacecraft and do not receive telemetric information, are not clear to us,” an apparent reference to the Americas.

Russia has not succeeded in sending a spacecraft to Mars since the 1980s. An attempt in 1996 to launch a Mars lander that could burrow below the planet’s surface failed because of a flaw in the rocket that carried it.
