Enters safe mode
At 1:54 pm New Horizons’ autonomous autopilot recognizes a problem, stops communicating with mission control on Earth, switches from the main to the backup computer and puts the probe into safe mode. It then begins to send information to engineers to help diagnose the problem. At 3:15 pm communication is restored. At 4:00 pm the team meets to resolve the problem and restore the probe to its flight plan. The probe is not able to collect science data at this time.
