Shelved in 2001, the Deep Space Climate Observatory (DSCOVR) satellite is finally ready for its time in the spotlight, or more accurately, the sunlight. On February 11, DSCOVR began its million-mile journey to Lagrange point 1 (or L1 orbit), an orbital sweet spot between Earth and the Sun. There, gravitational forces between the Sun and Earth are perfectly balanced, and the satellite will orbit the Sun like a planet.
