NASA is nearing completion of two major structural restoration projects for the B-2 Engine Test Stand at the Stennis Space Center in Mississippi, marking critical milestones for testing the core stage of the new heavy-lift launch vehicle, the Space Launch System (SLS). Reminiscent of the Saturn V launch vehicle used in the Apollo missions of the late 1960s and early 70s, NASA's new SLS is an advanced, heavy-lift launch vehicle that will provide an entirely new capability for science and human exploration beyond Earth's orbit. SLS will carry the Orion Multi-Purpose Crew Vehicle, as well as important cargo, equipment, and science experiments, to deep space. The massive 130 metric ton configuration will be the most capable, powerful launch vehicle in history. Towering a staggering 384 feet tall, it will provide 9.2 million pounds of thrust at liftoff and weigh 6.5 million pounds.
