Video: Saturday’s SpaceX launch

The launch of a U.S.-French oceanography satellite from California has been postponed from July 22 after engineers discovered contamination in one of the spacecraft’s thrusters at its factory in France.

The booster will first launch the Starlink 10-5 mission no earlier than the morning of Tuesday, Aug. 20. The static fire test happened Monday evening shortly after 7 p.m. EDT (2300 UTC).

SpaceX chief Elon Musk said last week he is “fairly confident” his company’s Falcon rockets can be made fully reusable within a couple of years, suggesting a renewed emphasis on outfitting upper stages for a scorching re-entry after engineers shelved the idea to focus on landing the launcher’s bigger booster stage.
