The next liftoff of SpaceX’s Falcon 9 rocket has been reset for no earlier than Feb. 8, NOAA and NASA officials said Tuesday, apparently to give the launch provider more time to prepare for the mission.

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.
