The launch of NASA's deep-space Orion capsule for a test flight around Earth was delayed on Thursday after a last-minute technical problem with its rocket, NASA said.

United Launch Alliance, a partnership of Lockheed Martin and Boeing that builds and flies the Delta 4 rocket, plans to try again at 7:05 a.m. EST (1205 GMT) on Friday.

Gusty winds at the seaside spaceport initially postponed the launch for more than an hour Thursday morning.
