Rainbow View of NASA’s RS-25 Engine Test

NASA conducted eight RS-25 engine tests in 2017 for the Space Launch System rocket. Flight preparations are complete for the four liquid fuel engines that will help power SLS on its first mission, and engineers began testing engines for the second mission that will carry crew. Four RS-25 engines will help power the SLS at launch, providing a combined 2 million pounds of thrust and firing in conjunction with a pair of solid rocket boosters.

The 10 motor segments have been cast for the two solid rocket boosters, and they are on track to be ready for the first integrated test flight.

With the boosters, total thrust at liftoff will exceed 8 million pounds.

NASA engineers conducted their first RS-25 test of 2017 on the A-1 Test Stand at Stennis Space Center near Bay St. Louis, Mississippi, on Feb. 22, 2017.

SLS Engine Section Test Article Loaded on Barge Pegasus

A structural qualification test article for the SLS engine section was shipped from agency’s Michoud Assembly Facility in New Orleans to NASA’s Marshall Space Flight Center in Huntsville, Alabama aboard the Pegasus barge.

At Marshall, the article underwent structural loads testing in which electronically controlled hydraulic cylinders pushed, pulled, twisted and bent the test article with millions of pounds of force to ensure the hardware can withstand the extreme forces of launch and ascent.

The engine section is located at the bottom of the rocket’s core stage and will house the four RS-25 engines and be an attachment point for the two solid rocket boosters.

Vacuum Pressure Integrated Suit Test

At NASA’s Johnson Space Center in Houston, technicians conducted a Vacuum Pressure Integrated Suit Test to verify enhancements to the spacesuit that astronauts will wear in the Orion spacecraft.

During this test, the suit is connected to life support systems and then air is removed from Johnson’s 11-foot thermal vacuum chamber to evaluate the performance of the suits in conditions similar to a spacecraft.

Orion’s Ogive Creates Safe Escape for Astronauts

In Sandusky, Ohio, engineers replicated, at full scale, the acoustics and vibrations Orion will experience during its missions in space using a wall of highly specialized speakers in the Reverberant Acoustic Test Facility at NASA Glenn Research Center’s Plum Brook Station.

The ogive panels protect the crew module during ascent as well as from the harsh acoustic and vibration environments experienced during launch.

Orion’s Parachutes Measure Up in High Pressure Test

In 2017 NASA successfully conducted three tests in the dessert of Yuma, Arizona as part of a series of tests to qualify Orion’s parachute system for flights with astronauts to help the agency safely return crew to Earth.

Each test simulated a possible scenario astronauts might experience under various conditions. At a facility in Promontory, Utah, engineers tested the abort motor for Orion’s launch abort system.

Orion’s three main orange and white parachutes help a representative model of the spacecraft descend through sky above Arizona, where NASA engineers tested the parachute system on Sept. 13 at the U.S. Army Proving Ground in Yuma.

Technicians Complete Final Welds Inside Liquid Oxygen Tank for First SLS Flight

All five major parts — the engine section, liquid hydrogen tank, intertank, liquid oxygen tank and forward skirt –are built and ready for additional outfitting and testing.

They will be connected together to form the 212-foot-tall core stage, the backbone of the SLS rocket. To build the two largest core stage structures — the liquid hydrogen and liquid oxygen tanks that hold more than 700,000 gallons of propellant — NASA welded the thickest structures ever joined using self-reacting friction stir welding.

The liquid oxygen tank–shown here as technicians inside the tank complete final welds to plug holes left by the robotic welder– is undergoing the first hydrostatic testing for NASA’s deep-space rocket, the Space Launch System (SLS). (Image by NASA/MSFC/MAF/Jude Guidry)

SLS Core Stage Pathfinder Arrives At NASA Michoud

The Space Launch System (SLS) core stage pathfinder, which is similar in similar in size, shape and weight to the 212-foot-tall core stage, was transported to NASA’s Michoud Assembly Facility.

To reduce the risk of first-time operations with one-of-a-kind spaceflight hardware for SLS, the agency is using the pathfinder to test new shipping and handling equipment and procedures from the manufacturing site to the test site to the launch site.

Space Launch System Booster Separation Test in Wind Tunnel

Engineers conducted several wind tunnel tests using SLS models at NASA’s Ames Research Center in California’s Silicon Valley and NASA’s Langley Research Center in Hampton, Virginia. Technicians used a distinct pink pressure-sensitive paint for some of the testing to understand the aerodynamic forces the rocket may experience on the launch pad and during flight.

To understand the aerodynamic forces as booster separation motors fire and push the solid rocket boosters away from the rocket’s core, engineers at NASA’s Langley Research Center are testing a 35-inch SLS model in Block 1B 105-metric ton evolved configuration in the Unitary Plan Wind Tunnel using a distinct pink paint.

Thumbs up for Evaluating of How Crew Will Exit Orion Spacecraft

During crew egress testing in the Gulf of Mexico, teams evaluated how the crew will get out of the capsule with assistance and by themselves. if the capsule lands upside down or turns over In high waves, uprighting bags are responsible for turning Orion right side up when it.

At NASA’s Johnson Space Center in Houston teams also performed a series of tests to evaluate how astronauts and ground crew involved in final preparations before Orion missions will quickly get out of the spacecraft if an emergency were to occur on the pad prior to launch

Using the waters off the coast of Galveston, Texas, a NASA and Department of Defense team tested Orion exit procedures in a variety of scenarios July 10-14. (Image by NASA)
