A communications satellite built for the South Korean military arrived at Cape Canaveral this week from an Airbus factory in France to begin final preparations for launch on a SpaceX Falcon 9 rocket in July.

Iran’s second try in less than a month to send a satellite into orbit apparently failed shortly after liftoff from a remote desert launch pad under daily surveillance from a fleet of commercial imaging spacecraft, according to U.S. government officials and independent analysts.

Jared Isaacman, an entrepreneur who flew to space twice as a commercial astronaut, was nominated for the position in early December and was voted favorably out of committee in late April. A replacement hasn’t been named.
