Daring Descent

A sailor descends from an MH-60S Sea Hawk to reach sailors assigned to the USS Somerset and NASA personnel during maritime recovery training off the coast of San Diego, March 19, 2025. The training is designed to prepare for NASA's Artemis II crewed mission, which will send four astronauts around the moon and beyond in the Orion spacecraft. NASA and the Defense Department will conduct a series of tests to demonstrate and evaluate the processes, procedures and hardware used in recovery operations for crewed lunar missions.
