Starship's fifth flight test could launch as soon as October 13, pending regulatory approval.

A live webcast of the flight test will begin about 30 minutes before liftoff, which you can watch here and on X @SpaceX. You can also watch the webcast on the new X TV app. The launch window will open as early as 7:00 a.m. CT. As is the case with all developmental testing, the schedule is dynamic and likely to change, so be sure to stay tuned to our X account for updates.

Flight 4 was a tremendous success. A fully successful ascent was followed by the first ever booster soft-landing in the Gulf of Mexico and Starship making it through a https://twitter.com/SpaceX/status/1798792222743122164, before its own landing burn and splashdown in the Indian Ocean.

The fifth flight test of Starship will aim to take another step towards full and rapid reusability. The primary objectives will be attempting the first ever return to launch site and catch of the Super Heavy booster and another Starship reentry and landing burn, aiming for an on-target splashdown of Starship in the Indian Ocean.

Extensive upgrades ahead of this flight test have been made to hardware and software across Super Heavy, Starship, and the launch and catch tower infrastructure at Starbase. SpaceX engineers have spent years preparing and months testing for the booster catch attempt, with technicians pouring tens of thousands of hours into building the infrastructure to maximize our chances for success. We accept no compromises when it comes to ensuring the safety of the public and our team, and the return will only be attempted if conditions are right.

Thousands of distinct vehicle and pad criteria must be met prior to a return and catch attempt of the Super Heavy booster, which will require healthy systems on the booster and tower and a manual command from the mission’s Flight Director. If this command is not sent prior to the completion of the boostback burn, or if automated health checks show unacceptable conditions with Super Heavy or the tower, the booster will default to a trajectory that takes it to a landing burn and soft splashdown in the Gulf of Mexico.

The returning booster will slow down from supersonic speeds, resulting in audible sonic booms in the area around the landing zone. Generally, the only impact to those in the surrounding area of a sonic boom is the brief thunder-like noise with variables like weather and distance from the return site determining the magnitude experienced by observers.

Starship will fly a similar trajectory as the previous flight test with splashdown targeted in the Indian Ocean. This flight path does not require a deorbit burn for reentry, maximizing public safety while still providing the opportunity to meet our primary objective of a controlled reentry and soft water landing of Starship.

One of the key upgrades on Starship ahead of flight was a complete rework of its heatshield, with SpaceX technicians spending more than 12,000 hours replacing the entire thermal protection system with newer-generation tiles, a backup ablative layer, and additional protections between the flap structures. This massive effort, along with updates to the ship’s operations and software for reentry and landing burn, will look to improve upon the previous flight and bring Starship to a soft splashdown at the target area in the Indian Ocean.

With each flight building on the learnings from the last, testing improvements in hardware and operations across every facet of Starship, we’re on the verge of demonstrating techniques fundamental to Starship’s fully and rapidly reusable design. By continuing to push our hardware in a flight environment, and doing so as safely and frequently as possible, we’ll rapidly bring Starship online and revolutionize humanity’s ability to access space.

• The Federal Aviation Administration may issue SpaceX its next Starship license in time for a Sunday launch attempt, CNBC has learned.
• Despite previously expecting that its license review could take until “late November,” a person familiar with the matter told CNBC the FAA’s process has sped up, opening the door for earlier approval.
• SpaceX and its CEO Elon Musk have been vocally critical of the FAA in recent weeks, alleging the company faces difficulties from “the current regulatory environment.”

The Federal Aviation Administration may issue SpaceX its next Starship license in time for a Sunday launch attempt, CNBC has learned.

SpaceX and its CEO Elon Musk have been vocally critical of the FAA in recent weeks, urging the federal regulator to speed up its license review for Starship’s fifth test flight. As recently as last week, the FAA said it did not expect to issue the license before “late November.”

Despite the ongoing review, SpaceX issued a statement Monday saying that the fifth Starship spaceflight “could launch as soon as October 13, pending regulatory approval.” The company did not indicate whether it expected to receive its license by Sunday.

But a person familiar with the matter said Tuesday that SpaceX’s seemingly aggressive target is possible because the FAA’s review process has sped up.

The regulator and partner agencies involved in the process conducted assessments more quickly than anticipated, the person told CNBC, with the U.S. Fish and Wildlife Service in the final stages of completing a review for the FAA. The person, who asked to remain anonymous to discuss the ongoing federal review, noted that it’s also possible any snags this week could take a Sunday attempt off the table and push approval to later this month.

In an updated statement to CNBC on Tuesday, the FAA removed its prior November estimate.

“In mid-August, SpaceX submitted new information for its proposed Starship/ Super Heavy Flight 5 mission. The FAA is continuing to review this information. The FAA will make a licensing determination once SpaceX has met all licensing requirements,” the FAA said.

The Fish and Wildlife Service referred CNBC to the FAA in response to a request for comment.

On Sept. 10, SpaceX issued a lengthy blog post saying the FAA was delaying Starship’s fifth launch over “superfluous environmental analysis,” alleging that the extended review was “for unreasonable and exasperating reasons” that represent difficulties in “the current regulatory environment” for companies seeking launch licenses.

The post in part criticized reports that SpaceX violated environmental regulations by using the Starship launchpad’s water deluge system in Texas without authorization. However, SpaceX settled fines levied by the Texas Commission on Environmental Quality and the federal Environmental Protection Agency regarding unauthorized water discharge.

Reuters first reported the FAA may approve a license as soon as this month but did not specify whether that could come as soon as Sunday.

An ambitious fifth launch


SpaceX aims to push development of its mammoth Starship rocket further with its fifth flight. It’s seeking to build on the progress of June’s fourth Starship test flight — which traveled halfway around the world for an intentional splashdown in the Indian Ocean.

As part of SpaceX’s effort to make Starship fully reusable, the company plans to attempt to return and catch the rocket’s 232-foot-tall booster.

After launching and separating from the upper Starship section of the rocket, the Super Heavy booster is expected to fly back to the launch site and land between a pair of so-called “chopsticks” on the tower. SpaceX emphasized that the catch attempt requires “thousands” of criteria to be met, or else the booster will divert from the return trajectory to instead splashdown off the coast in the Gulf of Mexico.

“We accept no compromises when it comes to ensuring the safety of the public and our team, and the return will only be attempted if conditions are right,” SpaceX said in a statement describing the flight.

The window on Sunday opens at 8 a.m. ET for the fifth Starship launch from the company’s facility near Brownsville, Texas.

Starship is both the tallest and most powerful rocket ever launched. Fully stacked on the Super Heavy booster, Starship stands 397 feet tall and is about 30 feet in diameter.

The Starship system is designed to be fully reusable and aims to become a new method of flying cargo and people beyond Earth. The rocket is also critical to NASA’s plan to return astronauts to the moon. SpaceX won a multibillion-dollar contract from the agency to use Starship as a crewed lunar lander as part of NASA’s Artemis moon program.
