NASA's groundbreaking rocket launch was scrubbed Monday after a slew of mechanical and weather-related issues.
So much is riding on the massive Artemis 1 mission ... it's the first launch of the massive, most powerful rocket ever ... it's an unmanned flight that will circle the moon and forge a path for astronauts to revisit the astronomical body in 2024 or 2025.
The flight was postponed due to an offshore thunderstorm, but then a fuel leak and other problems dogged mission control at the Kennedy Space Center.
The endgame is to build and send up a space station near the moon, where astronauts can live and regularly visit the satellite planet. Eventually, the space station will be a stopping off point for missions to Mars.
The first set of astronauts to visit space will include the first woman ever to step foot on the moon.
Monday's mission had 2 mannequins in the Orion capsule -- Helga and Zohar -- which contained fake female organs ... designed to test the effects of space radiation on women.
The next attempt to launch the rocket could be Friday.
