Major construction is complete on NASA’s largest new Space Launch System structural test stand, and engineers are now installing equipment needed to test the rocket’s biggest fuel tank. The 221-foot tall structure, started in May 2014, is critical for ensuring SLS’s liquid hydrogen tank can withstand the extreme forces of launch and ascent on its first flight, and later on the second flight, which will carry up to four astronauts in the Orion spacecraft on a journey around the moon, into the deep-space proving ground for the technology needed for the journey to Mars.
