NASA’s SLS missile successfully completed a hot fire engine test

NASA announced that its primary phase of the Space Launch System (SLS) has successfully completed a hot fire test this week at the Stennis Space Center in Mississippi. The four massive RS-25 engines were successfully launched for eight minutes and 19 seconds, completing testing and reaching a critical stage prior to NASA’s Artemis I. Artemis mission. I will send an unmanned Orion capsule on a trip around the moon and back to Earth.

This mission will pave the way for future missions that will transport astronauts to the moon for the first time since the Apollo era. The successful completion of the hot fire test was an accumulation of eight parts of Green Run Test campaign For an SLS missile. NASA says the team will use the data from the test to validate the basic design of the flight.

The SLS missile is the most powerful missile ever built by NASA, and during testing, it generated more than 1.6 million pounds of thrust within seven seconds. NASA describes the successful test as an important milestone in its goal of returning humans to the surface of the moon and ultimately beyond. NASA previously conducted a hot firing test of the SLS core stage on January 16.

However, the four rocket engines fired for only one minute before the test ended prematurely. NASA has spent time since January 16 trying to analyze the data to address issues that caused engines to shut down early the first time. After analyzing the data, a second fire test was scheduled to provide researchers with more data to verify the primary stage design.

This week’s successful test saw all four engines fire for a little over eight minutes, which is how long the rocket would take during each launch of Artemis. The successful hot fire test simulated different operating conditions, including moving four engines in specific modes to steer the thrusters and running them to power up to 109%, throttling, and back up throttle as in flight. Next to the primary stage is refurbishment, after which it will be shipped to the Kennedy Space Center in Florida for final assembly.
