@Bckempa tagging you based on your authorship. When this was released as one of the copyright owners, was this possible to publish on arxiv or similar or must it be hidden behind the AIAA paywall? Since this went through NASA's release process, it should be available through NTRS: https://ntrs.nasa.gov/api/citations/20220017761/downloads/Space_ROS_SciTech.pdf

There was no transfer of copyright since it was a U.S. Government work. I have a batch of website updates that got blocked by an issue with the forked CSS theme permissions during the OSRF re-org (long story) that I need to get back to. We can use the NTRS link.
