Starship returned to integrated flight testing with its second launch from Starbase in Texas. While it didn’t happen in a lab or on a test stand, it was absolutely a test. What we did today will provide invaluable data to continue rapidly developing Starship.
Starship successfully lifted off under the power of all 33 Raptor engines on the Super Heavy Booster and made it through a successful stage separation. The booster experienced a rapid unscheduled disassembly after its boostback burn following the successful stage separation while Starship's 6 second stage Raptor engines fired for several minutes as the Ship climbed to an altitude of ~150 kilometers.
With a test like this, success comes from what we learn, and today’s test will help us improve Starship’s reliability as SpaceX seeks to make life multiplanetary.

CAPE CANAVERAL, Florida—In three-and-a-half years of service, one of SpaceX's reusable Falcon 9 boosters stands apart from the rest of the company's rocket inventory. This booster, designated with the serial number B1058, has now flown 18 times. For its maiden launch on May 30, 2020, the rocket propelled NASA astronauts Doug Hurley and Bob Behnken into the history books on SpaceX's first mission to send people into orbit.
This ended a nine-year gap in America's capability to launch astronauts into low-Earth orbit and was the first time a commercial spacecraft achieved this feat. At that time, the rocket was fresh from SpaceX's factory in Southern California, glistening white in color, with a bright red NASA "worm" logo emblazoned on the side.
Over the course of its flights to space and back, that white paint has darkened to a charcoal color. Soot from the rocket's exhaust has accumulated, bit by bit, on the 15-story-tall cylinder-shaped booster. The red NASA worm logo is now barely visible. //
With Friday night's flight, this particular booster has launched 846 satellites, most of which have been Starlinks. When you let it sink in, that's a remarkable number. It's more than the total number of satellites in OneWeb's broadband network. The launch Friday night, numbered Starlink 6-26, brought the total number of functional Starlink satellites in orbit to more than 5,000, according to a tabulation by Jonathan McDowell, an astrophysicist and expert tracker of spaceflight activity. //
SpaceX officials often emphasize that, even after 277 launches of Falcon 9 or Falcon Heavy rockets, engineers learn something with each flight. It certainly helps when you get the majority of the rocket (the booster and the payload fairing) back after each launch, allowing technicians to perform inspections and refurbishment, occasional engine swaps, upgrades, or anything that needs to be done between missions.
