The planned launch of the space shuttle Discovery for its final mission has been postponed again after a fuel leak.
After 26 years of service, the vehicle is due to make one last flight to the International Space Station (ISS) before being retired to a museum.
Nasa has struggled all week to get Discovery off the ground, frustrated by poor weather and technical problems.
Escaping hydrogen detected midway through fuelling left Nasa no choice but to stand Discovery down once more.
The earliest another launch can be made is Monday.
US politicians have confirmed that the reusable orbiters should give way to a new era of spaceflight, and one by one these remarkable vehicles are taking a final bow.
