NASA Successfully Fires RS-25 Engine in Key Test Ahead of Artemis IV Mission
In a crucial step towards its ambitious Artemis IV mission, NASA has conducted a successful hot fire test of the RS-25 engine at the Stennis Space Center in Mississippi. The five-minute, 300-second test saw the engine reach up to 109% of its rated power level, providing confidence that it's ready for flight.
The engine, serial number 2063, was removed from the SLS core stage last year after a hydraulic leak on the main oxidizer valve actuator forced its initial installation to be scrapped. Engineers at NASA Stennis replaced the faulty component, and following standard procedure, the engine underwent hot fire testing to prove its worth for flight.
The test was conducted by a team of operators from NASA, L3Harris Technologies, and Sierra Lobo Inc., who worked together to push the engine to its limits. The results were deemed satisfactory, paving the way for the engine's installation on the SLS core stage for Artemis IV.
This successful test is a significant milestone in NASA's Artemis program, which aims to return humans to the Moon by 2025 and eventually send them to Mars. The RS-25 engines will play a critical role in powering the Space Launch System (SLS) rocket that will carry astronauts to the lunar surface.
With the engine now cleared for installation, NASA is targeting a launch window as early as February for its first crewed mission under the Artemis campaign, Artemis II. The SLS rocket will use four RS-25 engines, along with solid rocket boosters, to generate over 8.8 million pounds of thrust and lift the Orion spacecraft and astronauts into space.
The Artemis program is driven by NASA's goal to establish a sustainable human presence on the Moon, which will provide valuable scientific discoveries, economic benefits, and serve as a stepping stone for further exploration of the solar system.

just thinking about nasa going back to the moon in 2025 makes me so hyped!!! 
i mean who doesn't want to see humans walking on lunar surface again? 
the tech they're using is insane too, 109% power level is crazy! 
and can you believe they did that test with 300 seconds of continuous firing? 
the artemis program is gonna change our lives for sure. 
... I mean, NASA successfully tested their rocket engine for the Artemis IV mission, which is kinda good news? Like, they finally fixed the faulty component and proved it's fit for flight, yay 
. But let's be real, this is all just a distraction from the real problems we're facing 
. Have you seen the latest climate change reports? We've got 10 years left to save the planet 
...
...
can u believe dey got a new engine 4 their rocket and now dey r ready 2 launch people 2 space?? artemis iv sounds like such an awesome mission btw wut kinda scientific discoveries do ppl think dey gonna find in space??
can you believe they're actually getting ready to launch humans back to the moon?! I've been following this program for ages and it's so cool to see all these tests happening! The RS-25 engine is like, super important for the SLS rocket that's gonna carry the astronauts to lunar surface... but what if something goes wrong during launch? 
Like, have they thought of a backup plan or something?! I guess we'll just have to wait and see how it all unfolds... Fingers crossed for Artemis II! 
I mean, it's not just about powering rockets to space, but also thinking about the whole sustainability thing they're trying to achieve on the Moon... like, how are they gonna make sure it doesn't get all messed up after humans start living there? 
Guess we'll just have to wait and see how everything plays out in Feb. 
The RS-25 engine sounds like it's gonna be 
. But, now that the engine has been proven good to go 
, we're one step closer to getting back to the Moon 
. And now that it is, we're looking at a launch window as early as February 
! The Artemis program is all about establishing a sustainable human presence on the Moon and making progress towards Mars 
. I mean, we're talking 8.8 million pounds of thrust 
. The RS-25 engine is crucial for this mission, and it's reassuring to know that it's been thoroughly tested 
. Now, let's hope everything goes smoothly with Artemis II and we can get those astronauts on their way to the Moon soon! 
I'd say this whole thing is just more proof that we need to get our priorities straight and invest in sustainable energy solutions instead of space exploration
. seriously though, this is huge for the Artemis IV mission - gotta get those humans back on the moon ASAP!
