Tuesday is shaping up to be a busy day for SpaceX, with liftoff of a Falcon 9 rocket carrying a space weather satellite, an experimental booster flyback maneuver to test reusable launch technologies, and the splashdown of a Dragon capsule returning from the International Space Station.

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 blasted off Wednesday carrying NOAA’s Deep Space Climate Observatory, the world’s most distant weather satellite heading for a point a million miles from Earth. Launch from Cape Canaveral occurred at 6:03 p.m. EST (2303 GMT).
