The Deep Space Climate Observatory (DSCOVR) satellite today reached its orbit position 1 million miles from Earth, little more than 100 days after its winter launch. The National Oceanic and Atmospheric Administration (NOAA) satellite will become the first operational spacecraft in deep space to provide constant weather analysis.
DSCOVR will replace NASA’s aged Advanced Composition Explorer (ACE), launched in 1997 and operating a decade past its design life, and is expected to begin operations later this summer.
