SpaceX rolled out its next version of Starship to the pad Thursday (Aug. 5) as the company shoots for an ambitious orbital test.
The Starship prototype, known as SN20, left its production facility near the South Texas village of Boca Chica to arrive at the launch pad — joining the Super Heavy first-stage booster that arrived there two days before.
While SpaceX and founder Elon Musk have yet to comment on the rollout on Twitter, the event was carried live as the company prepares for this new mission — which SpaceX hopes to fly within the next few months, depending on technical and regulatory progress for the mission.

The 230-foot-tall (70 meters) Booster 4 will soon go through a series of pressurization and engine tests. Providing Booster 4 passes the trials, the rocket will then be prepared to send SN20 on a round-the-world trip. But it’s unclear when the rocket will launch, given that the U.S. Federal Aviation Administration is performing an environmental review of Starship’s launch operations, and we don’t know when that will finish.
The orbital flight plan calls for Booster 4 to splash down in the Gulf of Mexico, about 20 miles (32 kilometers) offshore, a few minutes after launch. SN20 will continue into orbit, make one circuit of Earth and then come down in the Pacific Ocean roughly 90 minutes after liftoff, near the Hawaiian island of Kauai.
NASA recently selected Starship as the crewed lander for its Artemis program, which plans to put humans on the moon later in the 2020s. Starship is a fully reusable, two-stage transportation system that SpaceX plans to use to ferry cargo and people to the moon, Mars and other destinations in the solar system.
SN20 (which is short for “Serial No. 20”) is the latest in a series of prototype launches for the Starship series. For example, a three-engine vehicle known as SN15 flew to a maximum altitude of 6.2 miles (10 km) in May and came down for a safe landing back on Earth.
The final version of the Starship spacecraft will have six Raptor engines, and the final Super Heavy version will likely be powered by 32 Raptor engines, Musk has said. The upper stage is 165 feet (50 meters) tall and is also known, confusingly, as Starship.
