names continues to drive technology exploration with the intent of making physical space exploration a reality. It could be argued as to what was the first commercially available “computer” to journey into space. Was it Hewlett Packard Enterprise’s (HPE) Spaceborne Computer system (SBC) in 2017? Or perhaps it was Bill and Dave’s answer to address the need for on-board orbital rendezvous calculations during the 1975 Apollo-Soyuz mission – the HP65 calculator? Or the GRiD laptop computer that flew aboard the space shuttle in the 1980s? There can be no doubt, however, that the 657 days that the SBC system spent aboard the ISS demonstrated that a modern, commercially available computer system could be successfully integrated into a space-based flight system in a timely fashion. The significance is multi-faceted. As we have moved beyond asking ourselves “can we do it” to “can we can afford it,” the technical and fiscal impact is huge across every space exploration project. The ability to leverage market dynamics and technological
