Refueling the massive Starship megarocket is part of SpaceX’s increased preparations for the impending test flight of the enormous vehicle.

The procedure, called a wet dress rehearsal (WDR), took place at SpaceX’s South Texas Starbase location on Tuesday, May 28. Massive amounts of liquid oxygen and liquid methane were pumped by the corporation into the Super Heavy and Starship (or simply “Ship”) phases of Starship, respectively.

“Starship and Super Heavy loaded with more than 10 million pounds of propellant in a rehearsal ahead of Flight 4. Launch is targeted as early as June 5, pending regulatory approval,” In an X post published today (May 29), SpaceX stated that.

It was this Starship vehicle’s second WDR, the first having happened on May 20.

The tests are a part of the preparations for Starship’s fourth mission, which could fly as early as June 5 (SpaceX said this in the X article). (To be clear, the business still requires permission from the Federal Aviation Administration of the United States to modify its Starship launch license.)

The first three Starship test flights happened this year on March 14, November 20, and April 20, 2023. With each flight after the other, the vehicle has performed better. During the first mission, which terminated four minutes after launch, for example, Starship’s two stages failed to split. However, trip 3 ended abruptly when the ship broke apart as it was reentering Earth’s atmosphere, lasting close to 50 minutes.

The main objective of Flight 4 is “getting through max reentry heating,” as stated by SpaceX CEO and founder Elon Musk in an X post from May 20.

Starship is almost 400 feet (122 meters) tall when fully stacked. Largest and most potent rocket ever constructed, it is meant to be quickly and completely reusable.

According to SpaceX, Starship has the potential to revolutionize spaceflight by enabling the financial viability of big exploration projects like Mars communities. NASA chose the craft to be the first crewed lunar lander for its Artemis moon mission because they believe in it.

As part of the Artemis 3 mission, Starship is presently slated to land NASA astronauts on the moon in late 2025. However, before humans set foot on the spacecraft, it must successfully complete numerous test flights.
