David Clark’s OCSS Suit Debuted on Artemis II
The astronauts on the Artemis II mission wore David Clark’s newest space suit.
In April of 2026, the Artemis II mission returned humans to deep space for the first time in over 53 years. NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with Canadian Space Agency astronaut Jeremy Hansen, wore David Clark Company’s Model S1041 Orion Crew Survival System, for launch on April 1st, and re-entry on April 10th. The crew also performed an in-flight test of the suits on April 5th, during their historic mission around the Moon. The Model S1041 OCSS is David Clark Company’s newest spacesuit. In addition to providing the crew protection from a variety of contingencies and hazards during dynamic phases of flight, the OCSS suit also serves as a backup safe-haven/secondary pressurizable environment, which the crew would use in the event of a deep-space cabin depressurization. As this was the first crewed test-flight of the Artemis program, the crewmembers tested the suits in microgravity, performing rapid donning evaluations and pressurizing the suits, to evaluate their custom fit and suit performance in a depressurized cabin scenario. David Clark is now working on OCSS suits for Artemis III, IV, and V. They are also working with Axiom Space on the suit that crewmembers will wear to perform spacewalks on the Moon.
