Credit: NOAAĭSCOVR was launched on Feb.11, 2015, and 100 days later it reached the Sun–Earth L1 Lagrange point and began orbiting about 1 million miles (1.5 million kilometers) from Earth. Positioned between the Sun and Earth, this location is called Lagrange point 1. ![]() Seven years later, in 2008, the Committee on Space Environmental Sensor Mitigation Options (CSESMO) determined the spacecraft would be “the optimal solution for meeting NOAA and USAF space weather requirements.” The satellite was removed from storage in November 2008 and recertified for launch with some modifications.ĭSCOVR orbits about 1 million miles (1.5 million kilometers) from Earth. The spacecraft originally was slated for launch on STS-107, the tragic mission of Space Shuttle Columbia in 2003, but Triana was canceled in 2001 and the satellite was put into storage. It was meant to be a NASA Earth science mission to provide an almost continuous view of Earth from space and to use a radiometer to take direct measurements of sunlight reflected and emitted from Earth. The project originally was called Triana, a mission conceived in 1998 by then-Vice President Al Gore. It acts like a sensor buoy at sea that warns of an oncoming tsunami- DSCOVR can warn forecasters 15 to 60 minutes before solar storms reach Earth.ĭSCOVR is a joint mission between NASA, NOAA, and the USAF and was designed as a successor to NASA’s Advanced Composition Explorer (ACE). The Deep Space Climate Observatory, or DSCOVR, gives real-time solar wind observations so that forecasters can provide early warnings about geomagnetic storms.
