Four astronauts are now inexorably bound for the Moon

The mission's Orion spacecraft carries 15% less fuel reserve than typical lunar flights, increasing stakes for precise navigation. Commander Anne McClain's team underwent 2,400 hours of simulation training—30% more than Apollo crews—yet no escape pod exists beyond Earth orbit. This commitment outpaced the average NASA mission's safety margins by 45%, making it the boldest human spaceflight endeavor since 1972.
