SpaceX is getting ready to launch the newest prototype of its next-generation Starship rocket on Wednesday, in a high-altitude flight that represents the firm’s most bold check to date.
Starship prototype Serial Number 8, or SN8, will goal to fly as excessive as 12.5 kilometers, or about 41,000 ft. That’s considerably increased than the pair of 500-foot flight checks that SpaceX accomplished with prototypes SN5 and SN6 earlier this 12 months.
The attempt comes a day after SpaceX practically launched the rocket however was stopped quick by a final second engine challenge. The firm has since reset for one more attempt.
Notably, the objective of the SN8 flight is just not essentially to attain the most altitude, however moderately to check a number of key elements of the Starship system.
“This suborbital flight is designed to test a number of objectives, from how the vehicle’s three Raptor engines perform to the overall aerodynamic entry capabilities of the vehicle (including its body flaps) to how the vehicle manages propellant transition. SN8 will also attempt to perform a landing flip maneuver, which would be a first for a vehicle of this size,” SpaceX mentioned in a assertion on its web site.
Given the a number of improvement milestones the firm is enterprise with the SN8 flight, SpaceX CEO Elon Musk gave the rocket low odds of full success on the first attempt.
“Lot of things need to go right, so maybe 1/3 chance,” Musk mentioned.
Starship SN8 is constructed of stainless-steel, with the prototypes representing the early variations of the rocket that Musk unveiled final 12 months. The firm is creating Starship with the objective of launching cargo and as many as a 100 individuals at a time on missions to the Moon and Mars.
While SpaceX’s fleet of Falcon 9 and Falcon Heavy rockets are partially reusable, Musk’s objective is to make Starship totally reusable — envisioning a rocket that’s extra akin to a industrial airplane, with quick turnaround occasions between flights the place the solely main price is gasoline.
The firm is constructing and testing the Starship prototypes at its rising facility in Boca Chica, Texas. The facility on the coast of the Gulf of Mexico, about 20 miles east of the Texas metropolis of Brownsville on the Mexico border.

SpaceX additionally famous that it has accomplished over 16,000 seconds – or practically 4 and half cumulative hours – of checks operating its Raptor collection of engines, that are constructed to energy Starship.
