SpaceX to launch newly upgraded Starship V3 megarocket
· UPIMay 21 (UPI) -- SpaceX on Thursday evening is set to launch the first test flight for its redesigned Super Heavy megarocket, the largest rocket ever built, from its new Texas launch pad.
The launch also will test upgraded systems on Starship, including the deployment of 22 Starlink satellite simulators, intentionally stressing the ship's new flight control flaps and will attempt the "dynamic banking maneuver" that it eventually will use to help land.
The uncrewed test flight, which has a 90-minute launch window from SpaceX's Starbase in South Texas that opens at 6:30 p.m. EDT, will be the 12th flight for Starship as the company develops what is expected to be a primary vehicle for NASA's Artemis missions to the moon.
"The flight test's primary goal will be to demonstrate each of these new pieces in the flight environment for the first time, with each element of the Starship architecture featuring significant redesigns to enable full and rapid reuse that incorporate learnings from years of development and testing," SpaceX said on its website.
The V3, which is 408 feet tall and more powerful than previous Super Heavy rockets, includes 33 redesigned Raptor engines -- Starship has six of its own -- will take off from South Texas for a round of primary tests similar to previous launches.
The rocket, SpaceX said, is hoped to successfully launch, ascend, separate from the second stage -- Starship -- and then perform boostback and landing burns in the Gulf of Mexico.
"As this is the first flight test of a significantly redesigned vehicle, the booster will not attempt a return to the launch site for catch," the company said.
During the hot-stage separation, Starship will light its engines to enter a sub-orbital path, performing tests and then splashing down in the Indian Ocean.
Tests of the space vessel are important as NASA's Artemis III mission in 2028 is expected to test connecting the Orion crew capsule to both Starship and Blue Origin's Blue Moon, although Blue Moon has yet to be launched for its first test flight.
Starship also is expected to be the ship that delivers Americans back to the moon in the next several years.
