The SAS is primarily noted for two activities:

• Space policy activity and review reports, known as SAS updates, which were emailed and web posted at irregular intervals. These included both factual current events and policy analysis, and were largely or entirely written by Henry Vanderbilt.
• Space Access conferences, held in the spring in Phoenix, Arizona, from 1994 to 2016. In 2019, the event to place in Fremont, California. There was also a Making Orbit conference held in Berkeley, California in 1992.

The Space Access conferences are well known in the reusable space launch development community and space launch vehicle communities for bringing together key players at most of the companies working in the field, ranging from large conventional aerospace companies such as Boeing and Lockheed-Martin, and smaller companies such as Rotary Rocket, XCOR Aerospace, Pioneer Rocketplane, Armadillo Aerospace and the like. NASA and the Federal Aviation Administration Office of Commercial Space Transportation also have consistently sent representatives. Many Ansari X-Prize team members were consistent attendees.

Presentations at the conference range from informal to viewgraphs and paper handouts. There is no conference proceedings, to encourage the free discussion of issues which participants may not want to go on documented record. Social networking among the industry leaders present is a major feature of the conferences as well.^[1]
