In a NASA replace, the company detailed two engine assessments accomplished by SpaceX for the Starship human touchdown system, which is anticipated for use for the Artemis 3 and 4 Moon landings later this decade.
The primary take a look at detailed by NASA was accomplished in August, which the company stated demonstrated a vacuum-optimized Raptor will be began within the excessive chilly situations from prolonged occasions in house, reminiscent of these on a mission to the Moon.
“One problem that differentiates Artemis missions from these in low Earth orbit is that the landers might sit in house with out firing for an prolonged time frame, inflicting the temperature of the {hardware} to drop to a stage beneath what they’d expertise on a a lot shorter low Earth orbit mission,” the Sept. 14 NASA blog update reads.
The company additionally detailed a take a look at that occurred in November 2021, which noticed a Raptor firing for 281 seconds on a take a look at stand to exhibit its means to carry out the powered descent portion of a Lunar Starship’s trek to the Moon’s floor.
“The take a look at had two objectives: to indicate Raptor’s means to vary the extent of engine energy over time, often known as its throttle profile, and for the engine to burn the total size of time of the powered descent section,” NASA’s replace reads. “The profitable take a look at offered NASA with early confidence within the firm’s engine growth.”
On the identical day, SpaceX launched video assessments on social media.

In April 2023, SpaceX carried out the primary built-in flight take a look at of the complete Starship launch system stack at its take a look at facility in South Texas. Whereas it gave the corporate quite a lot of beneficial knowledge, the flight was terminated some 4 minutes after liftoff after it started to veer out of its deliberate trajectory.
SpaceX has since made a variety of upgrades to each the bottom infrastructure and rocket, together with 63 “corrective actions” recognized in a mishap report for the primary flight. Starship’s second built-in flight take a look at might happen as early as subsequent month, pending regulatory approval and licensing from the FAA.
