WASHINGTON—SpaceX’s Starship rocket on Tuesday deployed its first batch of mock Starlink satellites in space and tested new heat shield tiles on its plunge through Earth’s atmosphere, clinching development milestones that had been held up by a streak of previous testing setbacks.
The giant 403-foot-tall (123 m) Starship system in its tenth test flight lifted off around 7:30 p.m. EDT (2330 GMT) from SpaceX’s Starbase facilities in south Texas, followed by its towering Super Heavy booster releasing the Starship upper stage into space three minutes later, dozens of miles above ground.
