NASA Space Launch System (SLS) Cubesat Opportunities on Artemis III, IV, and V Missions.

NASA is seeking proposals for CubeSat payloads to be deployed on the Artemis III, IV, and V missions. The opportunity is available for CubeSats that comply with the Space Launch System Use Policy and support NASA's space exploration goals. Proposals should include a letter of intent and a completed SLS cubesat questionnaire, and should be submitted by June 1, 2026, for initial consideration. The following are key points to consider: • The CubeSat should be either a 6U or 12U CubeSat, with a mass of under 14 kg for 6U and under 26 kg for 12U. • The anticipated mission profile should be compatible with deployment in Earth orbit or a lunar vicinity heliocentric disposal trajectory, or with deployment on a reentry trajectory from Earth orbit. • The spacecraft should be powered off from integration into the dispenser until deployment. • The proposer should be willing to publicly release science data obtained by the mission. • The proposer should be able to provide or procure communication infrastructure for the mission.
