"The test flight on Saturday from SpaceX’s facility in South Texas showed significant improvements over the first one in April. In the months after that flight, SpaceX installed a water suppression system designed to preserve the pad by dampening vibrations from the booster’s 33 Raptor engines. It seemed to work, and after Saturday’s flight, Musk wrote that he had “inspected the Starship launchpad, and it is in great condition! No refurbishment needed to the water-cooled steel plate for next launch.”

The flight also went much better. The spacecraft reached space this time, flying to an altitude of 93 miles, well above the 24 miles it hit last time. All 33 of the booster’s engines ignited; last time six failed. It made it through the point where the booster and spacecraft separate, which it did not last time. And the onboard flight termination system, designed to destroy the rocket if it veers off course, appears to have worked in a timely manner. Last time, there was a delay of about 40 seconds.

For all those reasons, “the situation is much more promising,” said George Nield, the former head of the FAA’s Office of Commercial Space Transportation. The question now is: “Did we learn whether something needs to be changed, fixed, replaced or modified?” he said. “And do any of those things have to do with public safety?”"
