NASA's long-awaited moonshot with astronauts is off until at least March because of leaking hydrogen fuel. The space agency announced the news Tuesday following a critical fueling test of its giant moon rocket in Florida. Hydrogen seeped from the base of the rocket during Monday's dress rehearsal, which went into overtime Tuesday because of all the problems. Officials say the delay will allow the launch team to conduct another practice countdown before committing four astronauts to humanity's first moonshot in more than half a century. With their launch now off until at least March 6, the three Americans and one Canadian can now emerge from quarantine.
