DSCOVR was placed in operation at the L1 Lagrange point to monitor the Sun, because the constant stream of particles from the Sun (the solar wind) reaches L1 about 60 minutes before reaching Earth. DSCOVR will usually be able to provide a 15- to 60-minute warning before a surge of particles and magnetic field from a coronal mass ejection (CME ...
DSCOVR is unofficially known as GORESAT, because it carries a camera always oriented to Earth and capturing full-frame photos of the planet similar to the Blue Marble. This concept was proposed by then-Vice President of the United States Al Gore in 1998 [4] and was a centerpiece in his 2006 film An Inconvenient Truth. [5]
DSCOVR is now in its final orbit: a place called Lagrange point 1 (L1), located a million miles away from our planet or around four times farther than the moon. That position gives the satellite a ...

Along with Aditya-L1, Wind, Advanced Composition Explorer (ACE), and Deep Space Climate Observatory (DSCOVR), SOHO is one of five spacecraft in the vicinity of the Earth–Sun L1 point, a point of gravitational balance located approximately 0.99 astronomical unit (AU) from the Sun and 0.01 AU from the Earth.

Animation of Advanced Composition Explorer's orbit viewed from the Sun Earth · Advanced Composition Explorer ACE in orbit around the Sun–Earth L 1 point. Advanced Composition Explorer (ACE or Explorer 71) is a NASA Explorer program satellite and space exploration mission to study matter comprising energetic particles from the solar wind, the interplanetary medium, and other sources.
