NASA test-fired the RS-25 engines that will power Artemis program missions. These upgraded shuttle-era engines will drive the Space Launch System, sending astronauts toward the Moon and laying the groundwork for long-term lunar exploration. | SpaceEve

Mir was a modular space station operated from 1986 to 2001, serving as a long duration laboratory for biology, physics, Earth observation, and human endurance in microgravity. It hosted crews for months at a time and became the foundation for later international cooperation in space, including the Shuttle Mir missions that led directly to the ISS era.
