First SLS Work Platform Installed in KSC's Vehicle Assembly Building High Bay 3

From NASA: “Inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, the 325-ton crane lifts the first half of the K-level work platforms up for installation in High Bay 3 on Dec. 22. The platform will be secured into position on tower E, about 86 feet above the floor.” Photo Credit: […]

Capping A Milestone Year, NASA Announces Completion of SLS Critical Design Review

From NASA: “For the first time in almost 40 years, a NASA human-rated rocket has completed all steps needed to clear a critical design review (CDR). The agency’s Space Launch System (SLS) is the first vehicle designed to meet the challenges of the journey to Mars and the first exploration class rocket since the […]

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: NASA

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 for […]

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 Launch […]
