The engine that will drive America’s next great rocket to deep space blazed through its first successful test January 9 at the agency’s Stennis Space Center near Bay St. Louis, Mississippi. The RS-25 fired up for 500 seconds on the A-1 test stand at Stennis, providing NASA engineers critical data on the engine controller unit and inlet pressure conditions. This is the first hot fire of an RS-25 engine since the end of space shuttle main engine testing in 2009. (NASA/Stennis) (Continued on page 2) www.nasa.gov Space Launch System Booster Ready to Fire A full-scale version of the booster for SLS is ready to fire for a major ground test and is paving the way on NASA’s journey to Mars. The two-minute, full-duration static test — scheduled for March 11 at booster prime contractor ATK’s test facility in Promontory, Utah — is a huge milestone for the program and will qualify the booster design for high temperature conditions. This type of test typically only comes after multiple years of development and signifies major progress being made on the rocket. Once this test and a second, low-temperature test planned for early 2016 are complete, the hardware is qualified and ready for the first flight of SLS. (ATK) RS-25 Engine Testing (cont’d) “It was the culmination of a tremendous amount of work at early-January facility outage at the A-1 stand. The team Marshall, at Aerojet Rocketdyne and especially at Stennis thoroughly assessed the issue and decided to proceed, Space Center,” Liquid Engines Manager Steve Wofford concluding that the risk to the test engine and the chance said. “It was a great team accomplishment. I told our team of a premature engine shutdown were low. Ultimately, it that the engine ran on hydrogen, oxygen and especially required close cooperation among program, institutional on the hard work, dedication, and attention to detail from and even commercial interests to carry out the test before them.” the scheduled test stand shutdown. The entire engine/test team faced several challenges to “It was also a good study in risk management and the refurbish the test stand, develop a new engine controller willingness to carefully assess, understand and accept a and modify and test an RS-25 for the first time since 2009. bit of elevated technical risk in order to achieve this major milestone for the engine office and SLS,” said Bill Hill, A technical issue that surfaced before the holiday break deputy associate administrator for Exploration Systems threatened to push the test date beyond a planned Development. 2 Spaceflight Partners: Dynetics EDITOR’S NOTE: Every month, SLS Highlights turns the spotlight on one of the many industry partners helping to create the largest rocket ever built for human space exploration. In this issue, we profile Dynetics of Huntsville, Alabama. Dynetics of Huntsville, Alabama, is supporting Boeing on work for the SLS core stage. (Dynetics) Dynetics, an employee-owned, engineering and SLS, these structural tests executed at NASA’s manufacturing company, is supporting Boeing in the Marshall Space Flight Center will validate design and manufacture and assembly of the intertank forward analysis activities and help qualify the SLS core stage and the liquid hydrogen aft SLS structural test design for flight loads. simulators. These simulators emulate mechanical properties for structural testing of the core stage Dynetics also is working with Boeing on the intertank and liquid hydrogen tank. The intertank and development of the SLS core stage thrust vector liquid hydrogen tank are part of the SLS core stage, control exhaust gas heat exchanger. The heat which will store cryogenic liquid hydrogen and liquid exchanger will use cold gas from the exhaust of oxygen that will feed the vehicle’s RS-25 engines. the core stage auxiliary power unit to maintain an Boeing is designing, developing and manufacturing acceptable temperature range for the hydraulic fluid, the 200-foot core stage for NASA. used in the thrust vector control system.

Dynetics will build two of those This includes thrust vector control performance barrels using its Research and Development and analysis, as well as design and integration support for Solutions Complexes in Huntsville, Alabama. the propulsion system. As a required step before the first flight test of the 3 Mini Models Fire Up for SLS Base Heating Tests A 2-percent scale model of the SLS core stage RS-25 engines, in the two pictures below, and a model of the SLS without the twin boosters, right, is used for nominal, core-stage-only testing at CUBRC, Inc. in Buffalo, New York. NASA is working in close collaboration with CUBRC to test mini models of the SLS propulsion system and entire vehicle in a shock tunnel at the facility. The test series will provide data on the convective heating environments that the base of the rocket will experience upon ascent. That data will be used to verify flight hardware design environments and set specifications for the design of the rocket’s base thermal protection system.
