The first test launch of NASA's new deep space capsule, Orion, has been postponed until later today because of wind gusts and technical issues with the rocket.
It follows a number of aborts at Florida's Cape Canaveral, during the nearly three-hour launch window this morning.
The plan for the capsule is to carry humans to an asteroid or Mars in the coming years.
The capsule's four-and-a-half hour test flight is due to carry the spacecraft around the Earth twice before splashing down in the Pacific Ocean.
