SLS test article shipped

The last of four structural test articles for NASA's Space Launch System (SLS) was loaded onto NASA's Pegasus barge Wednesday at NASA's Michoud Assembly Facility in New Orleans. The barge will deliver the liquid oxygen (LOX) tank test article to NASA's Marshall Space Flight Center in Huntsville, Ala., for structural testing. The LOX tank is one of two propellant tanks in the rocket's core stage that will produce more than 2 million pounds of thrust to help send Artemis 1, the first flight of NASA's Orion spacecraft and SLS, to the Moon. The nearly 70-foot-long test article is structurally identical to the flight version. SLS is being developed to send astronauts into deep space. (Source: Space Daily, 06/28/19)
