WASHINGTON — A joint NASA/NOAA space craft that monitors space weather and supplies vision of Earth continues to be off line for more than a week due to a problem using its placement system.
The Deep Space Climate Observatory, or DSCOVR, space craft went into a”safehold” June 27, interrupting its mathematics observations by the campuses in the Earth-sun l 1 Lagrange point, 1.5 million kilometers by the Earth at the direction of their sun.
NOAA spokesman John Leslie said July 5 which engineers placed the spacecraft to safehold to”first assess and then work to resolve a technical issue inside the system that maintains the satellite’s standing .” He said while that job is underway, the space craft isn’t returning data.

The assignment of DSCOVR will be to monitor wind requirements. While DSCOVR is in safehold,” Leslie said NOAA’s Space Weather Prediction Center will instead rely on data from the Advanced Composition Explorer (ACE) and Solar and Heliophysic Observatory (SOHO) spacecraft, which, for example DSCOVR, are at the Earth-sun l 1 point, as well as instruments on weather satellites in geostationary Earth orbit.
DSCOVR has suffered a number of safeholds at the past, but people have lasted just a question of hours. Engineers speculated those earlier safeholds were due to cosmic ray hits on spacecraft electronics. Leslie didn’t give a schedule for resuming operations of DSCOVR.
While DSCOVR’s chief mission is space weather tracking, the space craft is perhaps best called an Earth-facing camera called Earth Polychromatic Imaging Camera (EPIC). That camera takes full-disk pictures of this Earth that may be used for global monitoring of ozone and aerosols, as well as clouds and vegetation.
EPIC goes to the initial mission for DSCOVR. NASA suggested the assignment, afterward called Triana, at the request of Vice President Al Gore to provide the full opinion of the planet. The assignment was placed on hold early at the administration of President George W. Bushalong with the space craft put into storage. The Obama government resurrected the assignment underneath the DSCOVR name and with a brand fresh emphasis on space weather monitoring.
The Trump government suggested terminating EPIC operations. Its NASA budget requests for fiscal years 2018 and 2019 contained no funds for EPIC, tips that didn’t influence the total DSCOVR assignment, financed by NOAA. Congress rejected those proposals including funding for operations inside their own final appropriations bills.
NASA failed to repeat the effort to finish funding of DSCOVR in its own fiscal year 20 20 budget request. The agency’s budget proposition sought $1.7 million for DSCOVR operations, the same amount it received from 2018.
