To develop the first Space Chemistry Roadmap, a consortium of companies contacted Chemical Marketing & Economics (CME) to leverage the CME NASA Symposium and establish the Space Chemistry Roundtable (SCR) at the recommendation of the NASA Chief Scientist James Green. The first meeting was held on August 23, 2022, prior to the CME NASA Earth & Space Sustainability (CNESS) Summit held at the University of Chicago Rubenstein Forum. It brought together leaders from industry, academia, government, media and the public. 

The CME NASA Symposium takes place annually, or semi-annually, at major convention centers in USA as part of international meetings on the chemical sciences. The symposia is sponsored by scientific organizations such as I&EC, POLY and PMSE . Symposia have been held in Washington, DC; Boston, MA; Orlando, FL; and Atlanta, GA. Past speakers include Nobel Laureates Frances Arnold and Eric Betzig, Craig Venter, Robert Langer (MIT), James Green (NASA), Peter Eckes (BASF) and other eminent figures. Abstracts submissions are by invitation only. Attendees must register through the ACS website.

The CME NASA Earth & Space Sustainability (CNESS) Summit is a free outreach event held immediately after the CME NASA Symposia. An evening reception follows the conference. Admission to the conference and the reception is by invitation only. The CME NASA Earth & Space Sustainability afternoon program brings together thought leaders from industry, academia and government to advance sustainable innovation in the chemical sciences including energy, materials and life sciences.
