The solar wind monitoring satellite DSCOVR has gone into safe mode.
It is at present unclear what the problem is, or whether they can recover the spacecraft.
DSCOVR’s history is packed with political shenanigans. It was first proposed by Gore as Triana, with its only purpose to take global pictures of the Earth so Gore and the left could use these images for environmental propaganda. Bush canceled it, partly because it really had no legitimate scientific purpose and partly to prevent the left this propaganda tool. It was resurrected during the Obama administration but with a more useful purpose, providing early solar wind data so that Earth-based power grids could get prepared should a major solar storm be incoming. NASA’s other solar wind monitors ACE and SOHO, were already decades beyond their planned lifespan, and the space agency, the solar weather community, and especially the world’s electrical power industry, was desperate to get a new satellite in space.
Ironically, with DSCOVR’s shutdown we are still dependent on ACE and SOHO. Nor is there any replacement satellite anywhere close to launch.
