The U.S. Space Force’s third new-generation GPS 3-series navigation satellite has arrived in Florida for final processing and fueling ahead of a launch currently targeted for April 29 aboard a SpaceX Falcon 9 rocket.

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.

Officials from SpaceX, NOAA, NASA and the U.S. Air Force hold the prelaunch news conference for Falcon 9 rocket launch of the Deep Space Climate Observatory.
