A new space weather observatory launched in February has completed a four-month journey to an operating post a million miles from Earth, NOAA announced Monday.

SpaceX’s Falcon 9 rocket stands on Cape Canaveral’s Complex 40 launch pad ahead of a Feb. 8 launch attempt with NOAA’s Deep Space Climate Observatory.
