NASA has announced that the launch of its space shuttle Discovery has been delayed once more, until 3 December.
The US space agency had previously postponed the much-troubled launch until the end of November, following the diagnosis of a hydrogen gas leak in one of the external fuel tanks, as well as poor weather preceding the discovery of the leak.
That date has now been put back by three days, which NASA believes will give it time to correctly fix the leak and also allow technicians to review the repairs.
If conditions are adequate, Discovery will launch no later than 2.52am Eastern Standard Time.
Discovery was to shuttle NASA’s robotic astronaut, Robonaut 2, to the International Space Station along with other supplies during its original launch.
