NASA said on Tuesday that it was delaying its mission to send four astronauts on a journey around the moon, after issues arose during a critical test of its rocket.

NASA ran into exasperating fuel leaks during a make-or-break test of its new moon rocket Monday, calling into question how soon astronauts could take off for a trip around the moon .

The mission will see four astronauts take part in a 10-day fly around the Moon and back again.
