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.

Ready for a journey into the sun’s enigmatic, scorching corona, NASA’s Parker Solar Probe has been encapsulated inside the nose cone of its Delta 4-Heavy rocket for liftoff Saturday.

SpaceX says it is giving up on landing the Falcon 9 rocket’s first stage on a barge in the Atlantic Ocean after Wednesday’s launch of a NOAA space weather observatory due to rough seas in the booster recovery zone off Florida’s East Coast.
