Three panels for the Artemis II Orion stage adapter were built by AMRO Fabricating Corp. in South El Monte, California and shipped to Marshall where engineers and technicians from NASA are joining them using a sophisticated friction-stir welding process to form the Orion stage adapter. This critical part of NASA’s Space Launch System (SLS) rocket will send the Artemis II crew into lunar orbit. AMRO also built panels for the Artemis II launch vehicle stage adapter also currently being built at Marshall and the SLS core stage and the Orion crew module built at NASA’s Michoud Assembly Facility in New Orleans. All panels where joined with the same friction-stir welding process. The Artemis I Orion stage adapter, also built at Marshall, has been delivered to Kennedy Space Center where it will be stacked with the rest of the SLS rocket components. The adapter connects the Interim Cryogenic Propulsion Stage, the rocket’s upper stage that sends Orion to the Moon, to the Orion spacecraft. The Orion stage adapter has space for small payloads; on Artemis I it will transport 13 small satellites to deep space where they can study everything from asteroids to the Moon and radiation. SLS, the world’s most powerful rocket, along with NASA’s Orion spacecraft, will launch America into a new era of exploration to destinations beyond Earth’s orbit.
NASA completed the second of eight tests in the Green Run test series at the agency’s Stennis Space Center near Bay St. Louis, Mississippi, where the Space Launch System rocket’s core stage is installed in the B-2 Test Stand. The avionics power on and checkout test steadily brought the core stage flight avionics hardware, which controls the rocket’s first eight minutes of flight, to life for the first time. The three flight computers and avionics are located in the forward skirt, the top section of the 212-foot tall core stage, with more avionics distributed in the core’s intertank and engine section.
On June 24, 2020, engineers completed the Space Launch System (SLS) rocket’s structural testing campaign for the Artemis lunar missions by testing the liquid oxygen structural test article to find its point of failure.
For the final test, the liquid oxygen tank test article — measuring 70 feet tall and 28 feet in diameter — was bolted into a massive 185,000-pound steel ring at the base of Marshall’s Test Stand 4697. Hydraulic cylinders were then calibrated and positioned all along the tank to apply millions of pounds of crippling force from all sides while engineers measured and recorded the effects of the launch and flight forces. The liquid oxygen tank circumferentially failed in the weld location as engineers predicted and at the approximate load levels expected, proving flight readiness and providing critical data for the tank’s designers. The test concluded at approximately 9 p.m. CT. This final test to failure on the LOX STA met all the program milestones.
The rocket booster segments that will help power NASA’s first Artemis flight test mission around the Moon arrived at the agency’s Kennedy Space Center in Florida on Monday for launch preparations.
All 10 segments for the inaugural flight of NASA’s first Space Launch System (SLS) rocket and Orion spacecraft were shipped by train from Promontory, Utah. The 10-day, cross-country journey is an important milestone toward the first launch for NASA’s Artemis program.
Inside the Booster Fabrication Facility at NASA’s Kennedy Space Center in Florida, the Artemis I aft skirts for the agency’s Space Launch System (SLS) rocket’s twin solid rocket boosters are being readied for their move to the Rotation, Processing and Surge Facility (RPSF). In view, the left aft skirt assembly is attached to a move vehicle and moved out of a test cell. The aft skirts were refurbished by Northrop Grumman. They house the thrust vector control system, which controls 70 percent of the steering during initial ascent of the SLS rocket. The segments will remain in the RPSF until ready for stacking with the forward and aft parts of the booster on the mobile launcher in High Bay 3 of the Vehicle Assembly Building.
As it soars off the launch pad for the Artemis I missions, NASA’s Space Launch System (SLS) rocket is powered by two solid rocket boosters. Critical parts of the booster will soon head to NASA’s Kennedy Space Center in Florida in preparation for the Artemis I launch. Specialized transporters move each of the 10 solid rocket motor segments from the Northrop Grumman facility in their Promontory Point, Utah, to a departure point where they will leave for NASA’s Kennedy Space Center in Florida. The cross-country journey is an important milestone toward the first launch of NASA’s Artemis lunar program.
