While the outside of NASA’s new deep-space rocket, the Space Launch System (SLS) often gets all the glory, the inside works hard too. NASA is busy outfitting the rocket with what it needs for Exploration Mission-1, the first integrated mission of SLS and the Orion spacecraft. Engineers installed two sets of work platforms inside the rocket’s launch vehicle stage adapter. The adapter connects the rocket’s core stage with the interim cryogenic propulsion stage, which will fire its engine to send Orion into lunar orbit. SLS is the only rocket that can send Orion with its crew to the Moon. More on nasa.gov/sls Credit: NASA/MSFC/Amy Buck #nasa #sls #tech #nasatech #engineering #spacecraft #bigrockets
