Nasa delays Artemis 1 moon rocket launch again as tropical storm Ian looms

Third delay in the past month for test flight as technical issues and weather hamper US effort to return to the moon after five decades

Nasa is skipping Tuesday's launch attempt of its new moon rocket over concerns about a tropical storm headed to Florida that could become a major hurricane.

It's the third delay in the past month for the lunar-orbiting test flight featuring mannequins but no astronauts, a follow-up to Nasa's Apollo moon-landing program of a half-century ago.
