The Exploration Mission-3, or EM-3, is a planned 2024 mission of the Space Launch System and second crewed mission of NASA's Orion spacecraft. The intended goal of the mission is to deliver the ESPRIT and U.S. Utilization modules to the Lunar Orbital Platform-Gateway (LOP-G).

The EM-3 mission plan is to send four astronauts in the second Orion capsule into a near-rectilinear halo orbit around the Moon for a maximum of 26 days. It will also deliver two more elements of the future Lunar Orbital Platform-Gateway (LOP-G), a small space station in lunar orbit. The LOP-G components will be ESPRIT and the U.S. Utilization Module. Exploration Missions 3 through 8 would complete the assembly of the Lunar Gateway.
