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.

The deadly train wreck in southern Spain has cast a pall over one of the nation’s symbols of success. Spain leads Europe and is only second to China in the entire world in mileage of high-speed rail lines. The country's investment to link its distant cities across the Iberian Peninsula with fast trains boosted its economy and became a source of pride. Officials don't know the cause of the collision of the two trains on Sunday. And the first deadly crash on a high-speed stretch of track has put a blight on one of the crown jewels of contemporary Spain.
