About a month has passed since the first launch of SpaceX's "Version 3" Starship rocket, and the spaceflight company has already begun testing on its next such vehicle. SpaceX recently transported Ship 40, the upper stage in line to launch Starship's upcoming Flight 13 demonstration mission, to the Massey test site at its facilities in Starbase, Texas. Secured at its base, Starship performed a full-duration burn of one of its central Raptor 3 engines that lasted about 15 seconds. The test, called a static fire, is meant to confirm that the spacecraft's engines are in working order ahead of an actual launch. SpaceX posted a video of the test on X today (June 26). The Ship upper stage is equipped with six Raptor 3 engines — three sea-level engines, and three configured for optimized flight in the vacuum of space. The vehicle uses all six during ascent, but only a single sea-level engine during the final phase of its landing burn. Starship is SpaceX's super-heavy lift rocket, designed to be completely reusable. Its most recent test flight launched on May 22, completing a mostly successful demonstration of the vehicle's upgraded V3 hardware. At 408 feet (124.4 meters) tall, Starship V3 is the biggest, most powerful iteration of the launch vehicle to date, and is the first to sport SpaceX's new Raptor 3 engines.Despite a few malfunctions during the V3 debut last month, including failure of the rocket's Super Heavy booster to maneuver its way to a soft ocean splashdown as planned, SpaceX deemed the launch a successful test of the upgraded vehicle's new systems. In addition to the full outfit of Raptor 3s, V3 is equipped with enhanced aerodynamic grid fins, refined thermal protections, an increased fuel capacity and docking nodes to facilitate propellant transfer in space. That last capability is especially critical for Starship's success. Ship is capable of reaching low Earth orbit (LEO) using its onboard fuel, after Super Heavy lofts the stage through Earth's atmosphere, but once there, it can't fly much farther. (Note: Starship hasn't actually reached orbit yet. All of its launches to date have been suborbital.) To fly beyond LEO, Ship requires refueling from additional Starship launches designed to top off its tanks, a critical function of the giant spacecraft that SpaceX has yet to demonstrate, but that's expected to change this year.

To get there, NASA says the spacecraft will require at least 15 refueling flights. The first of those landing missions, Artemis 4, is scheduled for late 2028. Ship is also scheduled to launch as part of Artemis 3, during which astronauts aboard NASA's Orion spacecraft will dock with the lander to practice maneuvers with the mated vehicles, but is not expected to require refueling flights for that mission. The recent static fire with Ship 40 means SpaceX is progressing toward Starship's next full flight campaign, which will feature engine tests with all six of Ship 40's Raptors and all 33 of Super Heavy's. The company hasn't yet released any details about the upcoming Flight 13, but the company will likely attempt to launch the mission before the end of the summer.
