The Kepler spacecraft may have just been given a new lease in life, entering into a new K2 mission after it successfully completed its original task in 2012. However, it seems that the space telescope is showing some signs of fatigue. On April 7, during a scheduled contact, the spacecraft was discovered to be in Emergency Mode or EM. The exact cause of that mode switch remains unknown. Needless to say, the NASA team in charge of Kepler is hard at work at investigating the cause and getting the spacecraft back in working condition.
