After three check flights, SpaceX has proven that the world’s strongest rocket can attain house. Now, engineers should display the corporate’s next-generation Starship automobile can get again residence.
This would be the central goal for the fourth Starship check flight, which may occur as quickly as early June, in accordance with Elon Musk, SpaceX’s founder and CEO.
“Starship Flight 4 in about 2 weeks,” Musk posted on X, his social media platform, following a Starship countdown rehearsal Monday on the Starship launch website in South Texas. “Major objective is getting by max reentry heating.”
Practically able to fly
With Monday’s follow countdown, SpaceX accomplished one of many last main checks on the following Starship rocket earlier than it is able to fly. SpaceX’s launch group loaded greater than 10 million kilos of super-cold methane and liquid oxygen propellants into the Tremendous Heavy booster and Starship higher stage.
The practically 400-foot-tall (121-meter) rocket was absolutely stacked on its launch pad for the countdown rehearsal, which ended, as deliberate, earlier than the ignition of the booster’s 33 Raptor engines. SpaceX then drained the cryogenic propellants from the rocket, and floor groups eliminated the Starship higher stage from the booster Tuesday for extra work on the ship’s warmth protect. Just a few days earlier than launch, SpaceX will set up the rocket’s self-destruct mechanism, which might be used to destroy the automobile if it flies off target and threatens populated areas.
These are the ultimate main duties for the group at SpaceX’s Starbase facility earlier than Starship is able to take off on its fourth check flight. SpaceX can be ready for a business launch license from the Federal Aviation Administration, which is overseeing SpaceX’s inner evaluation of the earlier Starship check flight in March.
The FAA labeled the end result of that flight as a mishap as a result of the Starship misplaced management and disintegrated throughout reentry earlier than it may make a focused intact splashdown within the Indian Ocean. For SpaceX, the March flight was a powerful success. It was the primary time a Starship check flight reached close to orbital velocity, with full-duration burns by all 39 Raptor engines on the rocket’s first and second levels.
After the primary and second Starship check flights final yr, the FAA withheld a launch license for the following flight till regulators may evaluation all the outcomes of SpaceX’s investigation into what went improper on the prior mission. The FAA is chargeable for guaranteeing business house launches don’t endanger the general public.

Final week, an FAA spokesperson mentioned SpaceX requested that regulators approve the following Starship launch earlier than the formal conclusion of the mishap investigation into the March check flight. As an alternative, SpaceX requested the FAA to approve the following launch after figuring out the occasions of the earlier flight didn’t put the general public in danger. This might velocity up the licensing course of.
“If the FAA agrees no public questions of safety had been concerned within the mishap, the operator could return to flight whereas the mishap investigation stays open, supplied all different license necessities are met,” the FAA spokesperson mentioned.
SpaceX is already testing {hardware} for a number of rockets slated to fly later this yr, positioning the corporate to ramp up the Starship launch. The corporate can be constructing a second launch pad in Texas and plans two Starship launch websites in Florida to help a quicker launch cadence.
However there’s much more SpaceX must iron out with the Starship design earlier than it turns into operational.
