On April 8, 2016, SpaceX made history by sticking the landing of the Falcon 9 first stage on the drone barge in choppy seas. The Dragon cargo module also headed for the International Space Station with a Bigelow BEAM inflatable habitat module to attach to the ISS. This will be the first inflatable habitat seriously tested for endurance and viability as a lightweight, compact habitat for deep space exploration by the ISS crew. History could be made yet again, depending on how this technology once considered by NASA and dropped but picked up by Bigelow fares over the next two years. Time will tell.
