In early December, NASA’s Orion Program completed a “Delta” Critical Design Review (CDR) of the crewed spacecraft configuration that will first fly on Exploration Mission-2 (EM-2). This CDR focused on the changes between the uncrewed spacecraft configuration that will fly on Exploration Mission-1 (EM-1) and EM-2.
The CDR looked at the progress of designs for new or significantly modified Orion systems for EM-2. CDR Reviews began in September and culminated in a board meeting on December 3.
NASA, the European Space Agency (ESA), and their U.S. and European prime contractors are looking at the Orion EM-2 schedule, which currently targets launch of a four-person crew in the second half of 2022 on a lunar flyby test flight.
Delta CDR board on December 3
“The vehicle came through very well on this CDR,” Kirasich said. “This CDR was focused on the differences between EM-1 and EM-2, which primarily is in two areas. The ECLSS, the Environmental Control and Life Support System, and the crew displays.”
“Those two systems came through very clean, very few problems because predominantly the teams — even though we don’t fly them on EM-1 — we’ve been working them hard offline in labs and risk reduction development ...
