A Russian scientific spacecraft whizzing out of control around the Earth, and expected to re-enter the atmosphere on Saturday, may have failed because it was struck by some type of antisatellite weapon, the director of Russia’s space agency said in an interview published Tuesday. He did not say who would want to interfere with the spacecraft, which was intended to explore a moon of Mars. 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.
Phobos-Grunt, which took about five years to build and cost $160 million at current exchange rates, was launched from the Baikonur spaceport in Kazakhstan on Nov. 9; it also carried a small Chinese Mars orbiter.
