摘要

Europe's Rosetta comet-chaser satellite has apparently survived a dangerously close flyby of Comet 67P, which it is accompanying toward the sun, despite a dazzling of its star trackers by cometary debris and a subsequent shutdown of its science instruments. The European Space Agency on April 2 said Rosetta, which following the March 29 automatic emergency shutdown had been moved 400 kilometers away from the comet, had been cleared for a new, albeit less-close, approach to within 140 kilometers. "Limited science operations will be resumed in the coming days and weeks," ESA said, adding that a revised flight plan might be needed to assure that operations are preserved as the comet's orbit takes it closer to the sun before moving away again after Aug. 13.
