The retirement of the International Space Station (ISS) will occur before 2030 and the recent discovery of cracks in some of the oldest modules on the station highlight that this deadline is driven less by policy and more by the structure reaching the end of its service life. With this in mind, moves to replace the ISS with a commercial counterpart have shifted into top gear. The latest of these proposals comes from Blue Origin and Sierra Space, who propose to build Orbital Reef with the help of backers Boeing, Redwire Space, Genesis Engineering Solutions, and Arizona State University.
