NASA recently conducted a hot fire test of the RS-25 engine No. 2063 at the Fred Haise Test Stand located at the Stennis Space Center near Bay St. Louis, Mississippi. The test took place on January 22, 2026. During the test, vapor clouds could be seen escaping towards the sky, as captured in images from the event.
This hot fire test is a crucial step in the ongoing development and testing of rocket engines for future space missions. The RS-25 engine is part of the Space Launch System (SLS), a powerful rocket that will be used to carry astronauts and cargo on deep space missions. The successful completion of this test demonstrates progress towards ensuring the safety and reliability of the engine for future space exploration endeavors.
