NASA's Kepler spacecraft pauses science observations to download science data

Earlier this week, NASA's Kepler team received an indication that the spacecraft fuel tank is running very low. NASA has placed the spacecraft in a hibernation-like state in preparation to download the science data collected in its latest observation campaign. Once the data has been downloaded, the expectation is to start observations for the next campaign with any remaining fuel.

Since May 12, Kepler has been on its 18th observation campaign, staring at a patch of sky towards the constellation of Cancer it previously studied in 2015. The from this second look will provide astronomers with an opportunity to confirm previous exoplanet candidates and discover new ones. Returning the data back to Earth is the highest priority for the remaining fuel.

To bring the data home, the must point its large antenna back to Earth and transmit the data during its allotted Deep Space Network time, which is scheduled in early August. Until then, the spacecraft will remain stable and parked in a no-fuel-use safe mode. On August 2, the team will command the spacecraft to awaken from its no-fuel-use state and maneuver the spacecraft to the correct orientation and downlink the data. If the maneuver and download are successful, the team will begin its 19th observation campaign on August 6 with the remaining fuel.

NASA will provide an update after the scheduled download. The agency has been monitoring the Kepler spacecraft closely for signs of low fuel, and expects it to run out of in the next few months.

As engineers preserve the new data stored on the spacecraft, scientists are continuing to mine existing data already on the ground. Among other findings, recently 24 new planet discoveries were made using data from the 10th observation campaign, adding to the spacecraft's growing bounty of 2,650 confirmed planets.
