SpaceX is posting that the fourth flight test of its Starship could launch as soon as June 5, pending regulatory approval.

The fourth flight test is focused from achieving orbit to demonstrating the ability to return and reuse Starship and Super Heavy.

“The primary objectives will be executing a landing burn and soft splashdown in the Gulf of Mexico with the Super Heavy booster, and achieving a controlled entry of Starship,” according to SpaceX.

Software/hardware upgrades

For the upcoming flight, several software and hardware upgrades have been made to increase overall reliability and address lessons learned from the last Starship test – flight 3 last March.

In addition, the SpaceX team will execute operational changes, including the jettison of the Super Heavy’s hot-stage following boostback to reduce booster mass for the final phase of flight.

According to SpaceX, the flight 4 mission will fly a similar trajectory as the previous flight test. Starship is targeted to splashdown in the Indian Ocean.

“This flight path does not require a deorbit burn for reentry,” SpaceX adds, “maximizing public safety while still providing the opportunity to meet our primary objective of a controlled Starship reentry.”

Schedule is dynamic

“We’re continuing to rapidly develop Starship, putting flight hardware in a flight environment to learn as quickly as possible as we build a fully reusable transportation system designed to carry crew and cargo to Earth orbit, the Moon, Mars and beyond,” SpaceX explains.

A live webcast of the flight test will begin about 30 minutes before liftoff. Viewing will be available via the SpaceX website and on X @SpaceX.

The projected June 5 launch window opens as early as 7 a.m. Central Time.

“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,” SpaceX explains.
