NASA engineers declare Kepler space telescope ‘stable’ a few days after the spacecraft slipped into Emergency Mode (EM). Scientists were surprised when the planet-hunting probe went into EM last week, putting the next phase of its mission to study the Milky Way into jeopardy. NPR reports: Kepler, which is currently nearly 75 million miles away from Earth, placed itself into Emergency Mode sometime in the middle of last week. But it wasn’t until a scheduled contact on Thursday that mission engineers discovered the problem. That led NASA to declare a wider emergency, giving the mission priority access to communications through its Deep Space Network. NASA now says that Kepler mission engineers have recovered the spacecraft from its Emergency Mode. On Sunday, the craft directed its communications antenna toward Earth, “enabling telemetry and historical event data to be downloaded to the ground,” the space agency says. In its original mission to seek out exoplanets (planets that orbit other stars), Kepler found 4,696 candidates. More than 1,000 of those have been confirmed as planets, with 12 classified as being in the “small habitable zone” — a reference to the area near a star in which life might be supported. After its original mission [...]
