NASA's long-awaited moonshot with astronauts is off until at least March because of hydrogen fuel leaks that marred the dress rehearsal of its giant new rocket. It's the same problem that delayed the Space Launch System rocket's debut three years ago.

NASA plans to test the planned leak repair with a second dress rehearsal fueling test later this month.

After a major winter storm swept across the country in late January, a prolonged surge of Arctic air tightened its grip on large areas of the U.S. pushing temperatures well below normal. From the Midwest to the South, the impacts of snow and ice became more extreme.

By Joey Roulette WASHINGTON, Feb 3 (Reuters) - NASA pushed its Artemis II mission to March after wrapping up a launch rehearsal that uncovered issues with the massive Space Launch System rocket's fueling process,

As NASA prepares to send astronauts around the moon, a critical dress rehearsal on Monday will reveal whether its rocket is truly ready to fly.

NASA stopped short of completing a critical fuel test for its Artemis 2 SLS rocket because of hydrogen leaks that sound a lot like the problems they had during Artemis 1.

NASA’s first crewed lunar mission in more than 50 years won’t be getting underway this month after all. It had been targeting February 6 for the launch of the much-anticipated Artemis II mission that will take four astronauts on a flight around the moon,

Artemis II echoes the Apollo-era missions that paved the way for the first moon landing — and sets the stage for what comes next.

NASA began a two-day practice countdown Saturday leading up to the fueling of its new moon rocket, a crucial test that will determine when four astronauts blast off on a lunar flyby. Already in quarantine to avoid germs,
