WilliamsIn 2018, NASA will launch the first unmanned test flight of its wide body super heavy lift vehicle, the Space Launch System (SLS). That first launch will also test the first uncrewed version of the Orion spacecraft.

Crewed Orion/SLS missions are not scheduled to occur until at least the year 2021.Congress has directed NASA to reveal the design of a microgravity Deep Space Habitat (DSH) by 2018. Unfortunately, the American space agency continues to ignore the use of a DSH as a gateway for crewed missions to the lunar surface while simply ignoring the significant physiological problems associated with potential multiyear interplanetary missions within a microgravity environment.
