Live coverage: SpaceX supply ship returns to Earth

NASA astronaut Nick Hague and Roscosmos cosmonaut Alexandr Gorbunov walked through a launch day simulation as NASA and SpaceX prepared to conduct a static fire test of the Falcon 9 rocket. Ignition happened at 10:05 p.m. EDT (0205 UTC).

While Congress considers whether to provide funding NASA says it needs for a moon landing with astronauts before the end of 2024, several international partners voiced their intentions Monday to participate in the U.S.-led lunar exploration program.

Ten Iridium communications satellites rode a Falcon 9 rocket into orbit Friday from California in the eighth and final launch for Iridium’s upgraded network over the last two years, and the first of around 18 predicted SpaceX missions planned in 2019.
