Kepler Space Telescope Recovered from Emergency Mode
Alexander Neil / 4 years ago
It was recently reported that the deep space telescope, Kepler had run into trouble and had forced itself to enter its emergency mode. Thankfully the planet-hunting spacecraft has since returned to a stable state.
NASA’s Kepler team engineers were able to direct the communications array aboard the craft towards Earth and have begun the long process of downloading the data that could reveal the cause of the emergency. Due to the spacecraft being 75 million miles from Earth, any signal to and from it takes a whole 13 minutes.
When the telescope was first found to have run into issues late last week, NASA had declared a mission emergency, providing the Kepler team with priority access to the Deep Space Network, which is used to contact distant spacecraft. Due to emergency mode consuming vastly more fuel than normal, restoring Kepler’s functionality was a race against time before it would be unable to complete its mission. Now that Kepler has returned to a stable state, access to the DSN has returned to normal priorities.
Whether Kepler will be returned to “science mode” is yet to be decided by the mission engineers and they are currently performing health checks on all data received from the craft. At the time of failure, the telescope was only 14 hours away from beginning the next section of its ongoing mission, however, the craft has until July 1st to complete this stage, should it be deemed fit to return to full operation.
