Lunar Dress Rehearsal — 2 museum-grade prints that set the mood. Artemis I marked NASA's first integrated test of the Space Launch System and Orion spacecraft — the hardware stack intended to return humans to lunar orbit and eventually land crews on the Moon's south pole. The 25. Apollo 10 was the mission that made Apollo 11 possible — every critical sequence from lunar orbit insertion through LM separation, descent, ascent, and rendezvous was exercised over the Moon except the final landing burn. Stafford and Cernan reported the lunar surface up close; Young held Charlie Brown in orbit.
