A critical engine test for Nasa s new megarocket - the Space Launch System (SLS) - has ended early.
Shortly before 22:30 GMT (17:30 EST), the four engines ignited, burning for more than a minute before the event was aborted.
The core stage of the SLS was being evaluated at Stennis Space Center, near Bay St Louis, Mississippi.
The engines were supposed to fire for eight minutes to simulate the rocket s climb to orbit.
The SLS is part of Nasa s Artemis programme, which aims to put Americans back on the lunar surface in the 2020s.
