As part of a critical test before the first launch of the giant rocket, the agency plans to light
Today's engine test isThe final milestone in a series of tests by the Green Run agency to make sure the SLS rocket is ready for its first launch, called Artemis 1, which will send the Orion unmanned spacecraft around the moon. The first flight is scheduled for the end of this year.
SLS is NASA's next super-heavy rocketgeneration, which will ferry astronauts to the moon as part of the Artemis agency's lunar program. Launched by the end of this year, Artemis 1 will be the first in a series of missions that will culminate in NASA's first manned moon landing since Apollo. This mission, called Artemis 3, could happen as early as 2024 if all goes according to plan.
To this end, NASA is testing four enginesRS-25 massive SLS missile before launch. The agency systematically tests each engine and conducts start-day procedures such as refueling to ensure all systems are working as expected.
Combustion engine upcoming test -the final stage of the testing process. On Saturday, engineers will load the SLS booster with over 700,000 gallons of supercooled fuel before firing all four RS-25 engines simultaneously. This will be the first time that four RS-25 engines will operate simultaneously. The same engines powered the space shuttle, but the orbiter only took three to fly.
