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 is targeting March for the launch of four astronauts on a ten-day mission to circle the moon and return safely to Earth, traveling farther than any humans have ventured in deep space.

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’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,

NASA's Artemis II wet dress rehearsal faced setbacks today with two interruptions from a liquid hydrogen leak exceeding limits on the SLS rocket's core stage. LOX loading proceeded normally during the key pre-launch test simulating countdown operations.

The AI used the same data human planners employ to guide Perseverance through the Martian terrain. February marks the five-year anniversary of Perseverance ‘s time on Mars. But when it comes to trying out new things, NASA’s rover seems to be as active as it was on the day it first arrived on the Martian regolith.
