Drone’s view of Sunday’s SpaceX rocket landing

Stymied by Russian government dithering that has indefinitely grounded a launch on a modified Soviet-era missile, Iridium officials say that SpaceX agreed to move up to July the first of seven Falcon 9 launches from California with the company’s next-generation mobile communications satellites.

NASA managers held a flight readiness review Friday and cleared SpaceX to press ahead with work to ready a Falcon 9 rocket and Crew Dragon commercial ferry ship for launch March 2 on an unpiloted test flight to the International Space Station.

Mitsubishi Heavy Industries, the prime contractor for Japan’s H-2B rocket, said Friday that engineers concluded a fire on the launch pad during a countdown earlier this month was most likely sparked by static electricity and stimulated by oxygen. The H-2B rocket launch has been rescheduled for Tuesday to start a resupply mission to the International Space Station.
