Key Takeaways
- NASA will attempt its second Artemis 2 fueling test on February 19 after a hydrogen leak halted the first at T-minus 5 minutes
- Engineers spent two weeks repairing the hydrogen interface and analyzing data from the first test
- A successful test could enable a crewed lunar flyby mission as early as March 2026
- The four-person crew includes historic firsts: the first person of color and first woman to fly beyond low Earth orbit
- Liquid hydrogen's tiny molecular size and extreme cold make leaks a persistent engineering challenge
