SpaceX says it has identified and fixed the problem that caused its Falcon 9 rocket to fail during a launch earlier this month.
That failure occurred on July 11, as a Falcon 9 carried 20 of SpaceX's Starlink broadband satellites toward low Earth orbit. The rocket's first stage performed normally that day, but its upper stage sprang a leak of liquid oxygen, which prevented it from conducting an orbit-raising burn as planned; the Starlink satellites were deployed too low as a result and came back down to Earth in relatively short order, burning up in our planet's thick atmosphere.
