Testing of the new brain for the RS-25 engines that will help power the colossal Space Launch System (SLS) rocket uphill from launch pad 39B in the coming years has been on a roll at NASA’s Stennis Space Center all summer, and they just […]

First SLS Flight Engine Roars to Life for Testing at Stennis Space Center

The first SLS flight engine roared to life for testing at Stennis Space Center on March 10, 2016. Intended for the first crewed SLS mission, EM-2, the engine last saw action powering Space Shuttle Endeavor into orbit in 2011 on STS-134. Photo Credit: NASA

The first of 14 former space shuttle main engines, […]

Seventh RS-25 Test Fire of 2015 Closes Out First SLS Main Engine Test Series

The RS-25 engine fires up for a 535-second test Aug. 27, 2015 at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. This is the final in a series of seven tests for the development engine, which will provide NASA engineers critical data on the engine controller unit and inlet pressure conditions. Credits: […]

SLS Development RS-25 Engine Ignites for Successful Full Duration Test Fire #6

The world’s most efficient rocket engine came to life again today, unleashing 512,000 pounds of thrust and a thunderous roar across southern Mississippi and NASA’s Stennis Space Center during a 535-second full power test fire. The same engine that powered the space shuttle so reliably for years, the RS-25, will again be employed […]

SLS Development Engine Test Fire #4 Ignites With Longest Duration Firing Yet

RS-25 development engine test fire at Stennis Space Center near Bay St. Louis, Miss. Yesterday’s test fire, the fourth in the first series of seven planned test fires, ran for 650 seconds, the longest SLS RS-25 test fire yet. Four RS-25 engines will power the core stage of NASA’s new rocket, the Space […]
