SpaceX’s Falcon 9 rocket took off from Cape Canaveral on its 15th flight just before sunset Wednesday, putting on a spectacular sky show en route to space with a NOAA satellite to measure the solar wind.

A problem with a U.S. Air Force tracking radar kept a Falcon 9 rocket crowned with a NOAA space weather observatory grounded Sunday, forcing a long-delayed mission to stay on Earth an extra day.
