On November 29, NASA achieved a significant milestone in its Artemis project by conducting a comprehensive 650-second hot fire test of the RS-25 certification engine. This test, conducted by Danny Nowlin and his team at NASA, is part of a series of essential tests for the Space Launch System (SLS) missions, aimed at deep space exploration and enhancing our understanding of the universe for humanity’s benefit.
This third test of the RS-25 engine, conducted on November 29, plays a crucial role in a series of 12 tests designed to certify the engines for use in NASA’s SLS rocket, intended for Artemis missions. The testing process, which includes innovative manufacturing techniques like 3D printing, focuses on ensuring the engines’ reliability and performance for upcoming missions to the Moon and Mars. By testing these engines under conditions that surpass their normal operational limits, NASA aims to guarantee their safety and effectiveness.
The recent hot fire test of the RS-25 engine marks a significant step in the 12-test certification series, crucial for the SLS rocket’s operation in Artemis missions destined for lunar exploration and beyond.
Advancements in Engine Manufacturing Processes
NASA’s test series is directed towards certifying new methods for manufacturing RS-25 engines, which are vital for upcoming deep space missions starting with Artemis V. Aerojet Rocketdyne, a subsidiary of L3Harris Technologies and the leading engine contractor for the SLS rocket, is implementing innovative production techniques, including 3D printing, for the new RS-25 engines.
In a pivotal test for the SLS rocket’s RS-25 engine, NASA has accomplished a critical step forward for future Artemis missions to the Moon and Mars.
During the test, which lasted nearly 11 minutes (650 seconds), the RS-25 engine was dynamically gimbaled, or rotated around a central point, at the Fred Haise Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. This gimbaling method is essential for controlling and stabilizing the SLS rocket as it ascends into orbit.
Pushing the Limits of Performance
The November 29 test involved pushing the engine beyond its expected operational parameters during flight to ensure a margin of safety. The duration of the test, 650 seconds, exceeded the 500 seconds required for the RS-25 engines to power the SLS into space. Additionally, the engine was tested at 113% power level, surpassing the necessary 111% level for launching the SLS into orbit.
The latest test of the RS-25 engine on November 29 is a significant step towards certifying engines with new manufacturing processes for deep space missions.
Long-Term Mission Objectives and Engine Testing
NASA’s ongoing test series will continue until 2024, as part of its mission to return humans to the lunar surface for scientific exploration and to prepare for manned missions to Mars.
Each SLS flight is powered by four RS-25 engines, generating a combined thrust of 1.6 million pounds at launch and 2 million pounds during ascent. For Artemis missions I through IV, NASA and Aerojet Rocketdyne have modified 16 previously used space shuttle main engines, all tested and proven at NASA Stennis.
Comprehensive Engine Testing at Stennis
All new RS-25 engines intended for the SLS will undergo testing at NASA Stennis. These tests are carried out by a collaborative team from NASA, Aerojet Rocketdyne, and Syncom Space Services, with Syncom being the primary contractor for the Stennis facilities and operations.

This is such an inspiration, watching humanity reach for the stars! Go NASA, Artemis missions are gonna be epic, can’t wait to see more.
wow this is huge news! nasa’s really pushing the boundaries with the artemis missions, those engine tests sound super intense.
umm, did anyone else notice they are using engines from the space shuttle? that’s old tech, right? why not build completely new ones?
Interesting read but, I’ve got questions about the 3D printing part… how does that work for engine parts? Sounds risky but innovative.
i’m not a big space buff, but this is kinda cool? like, going to the moon again and maybe mars, it’s like sci-fi becoming reality.
