NASA is a step closer to returning astronauts to the Moon in the next five years following a successful test of RS-25 engine No. 2062 on Thursday at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. The latest “hot fire” was the culmination of four-plus years of testing for the RS-25 engines that will send the first four Space Launch System (SLS) rockets into space. When this specific engine fires again, it will help send astronauts aboard Orion around the Moon on a test flight known as Exploration Mission-2.
