Artemis II Moon Mission Day 2: First Humans to Leave Low-Earth Orbit in 54 Years
Back in 1972, the crew of Apollo 17 left low-Earth orbit and headed for the Moon. It was to be the final mission of the program, and the last time humans ventured that far out into space. Until now, that is, 54 years later, because the astronauts on board the Orion Integrity spaceship are now on their way to the Moon as well.
