NASA’s highly successful Kepler space telescope has had more than its share of near fatal experiences.
The latest happened in April when the spacecraft went into “Emergency Mode” which among other things allows for priority access to ground-based communications via NASA’s Deep Space Network. NASA noted at the time that the spacecraft is nearly 75 million miles from Earth, making the communication slow. Even at the speed of light, it takes 13 minutes for a signal to travel to the spacecraft and back.
The spacecraft has since returned to normal function.
