The Federal Aviation Administration has signaled to SpaceX that it won't approve a launch license for the next test flight of the Starship rocket until at least late November, the company said in a statement on Tuesday.

This is more than two months later than the mid-September timeframe the FAA previously targeted for determining whether to approve a launch license for the next Starship flight. SpaceX says the Super Heavy booster and Starship upper stage for the next launch—the fifth full-scale test flight of the Starship program—have been ready to launch since the first week of August.

"The flight test will include our most ambitious objective yet: attempt to return the Super Heavy booster to the launch site and catch it in mid-air," SpaceX said in a statement.

Pretty much every day for the last couple of weeks, workers wielding welding guns and torches have climbed onto SpaceX's Starship launch pad in South Texas to make last-minute upgrades ahead of the next test flight of the world's largest rocket.

Livestreams of the launch site provided by LabPadre and NASASpaceflight.com have shown sparks raining down two mechanical arms extending from the side of the Starship launch tower at SpaceX's Starbase launch site on the Gulf Coast east of Brownsville, Texas. We are publishing several views here of the welding activity with the permission of LabPadre, which runs a YouTube page with multiple live views of Starbase.

If SpaceX has its way on the next flight of Starship, these arms will close together to capture the first-stage booster, called Super Heavy, as it descends back to Earth and slows to a hover over the launch pad.

After SpaceX decided to launch orbital missions of its Starship rocket from Texas about five years ago, the company had to undergo a federal environmental review of the site to ensure it was safe to do so.

As a part of this multi-year process, the Federal Aviation Administration completed a Final Programmatic Environmental Assessment in June 2022. Following that review, SpaceX received approval to conduct up to five Starship launches from South Texas annually.

SpaceX has since launched Starship four times from its launch site in South Texas, known as Starbase, and is planning a fifth launch within the next two months. However, as it continues to test Starship and make plans for regular flights, SpaceX will need a higher flight rate. This is especially true as the company is unlikely to activate additional launch pads for Starship in Florida until at least 2026.

It's unclear yet how long SpaceX's workhorse Falcon 9 rocket will remain grounded as engineers investigate a rare launch failure last week, but the next test flight of the company's next-generation Starship vehicle appears to be on track for liftoff next month.

On Monday, SpaceX test-fired the 33 Raptor engines on the Starship rocket's Super Heavy booster at the company's Starbase facility in South Texas. The methane-fueled engines fired for about eight seconds, long enough for SpaceX engineers to verify all systems functioned normally. At full power, the 33 engines generated nearly 17 million pounds of thrust, twice the power output of NASA's iconic Saturn V Moon rocket.

SpaceX confirmed the static fire test reached its full duration, and teams drained methane and liquid oxygen from the rocket, known as Booster 12 in the company's inventory of ships and boosters. The upper stage for the next Starship test flight, known as Ship 30, completed the static fire of its six Raptor engines in May.

The Federal Aviation Administration approved the commercial launch license for the fourth test flight of SpaceX's Starship rocket Tuesday, with liftoff from South Texas targeted for just after sunrise Thursday.

"The FAA has approved a license authorization for SpaceX Starship Flight 4," the agency said in a statement. "SpaceX met all safety and other licensing requirements for this test flight."

Shortly after the FAA announced the launch license, SpaceX confirmed plans to launch the fourth test flight of the world's largest rocket at 7:00 am CDT (12:00 UTC) Thursday. The launch window runs for two hours.
