Photos: Orion launches at dawn

A three-minute test flight Tuesday morning over Cape Canaveral will help ensure NASA’s Orion crew capsule — the vehicle being built to carry astronauts back to the moon — can safely escape from a catastrophic failure on launch.

NASA officials released a nearly five-year, $28 billion plan Monday to return astronauts to the surface of the moon before the end of 2024, but the agency’s administrator said the “aggressive” timeline set by the Trump administration last year hinges on Congress approving $3.2 billion in the next few months to kick-start development of new human-rated lunar landers.

NASA will unveil the four crew members Monday who will fly around the moon on the first piloted flight of the agency’s Orion deep space capsule on the Artemis 2 mission as soon as late next year.
