The world’s most distant weather outpost is set for liftoff from Cape Canaveral on Sunday aboard a SpaceX Falcon 9 rocket, launching to a point a million miles from Earth to warn forecasters of solar storms that could disrupt global air traffic, satellite navigation and power grids.

Unfavorable high-altitude winds above Cape Canaveral on Tuesday kept a SpaceX Falcon 9 rocket loaded with a NOAA space weather observatory on the ground another day.

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.
