K2 Campaign 19 status update

The Kepler spacecraft began collecting science data on Aug. 29 for its 19th observation campaign. However, after being roused from sleep mode the spacecraft’s configuration has been modified due to unusual behavior exhibited by one of the thrusters. Preliminary indications are that the telescope’s pointing performance may be …

📡Spacecraft status

The Kepler spacecraft began collecting science data on Aug. 29 for its 19th observation campaign. However, after being roused from sleep mode the spacecraft’s configuration has been modified due to unusual behavior exhibited by one of the thrusters. Preliminary indications are that the telescope’s pointing performance may be somewhat degraded. It remains unclear how much fuel remains; NASA continues to monitor the health and performance of the spacecraft.
