Pluto mission's lift-off delayed
View at BBC NEWS
The US space agency, Nasa, has been forced to postpone the launch of its New Horizons mission to Pluto.
The launch site was experiencing gusting winds that had several times exceeded safe limits.
The spacecraft is now scheduled to lift off from Cape Canaveral, Florida, on Wednesday at 1316 EST (1816 GMT).
The probe was originally due to launch at 1824 GMT, but Nasa pushed back the launch seven times before finally deciding to scrub Tuesday's attempt.
Controllers kept postponing the launch time until running up against the end of Tuesday's launch window at 2023 GMT.
However, the high winds at Cape Canaveral Air Force Station refused to subside and Nasa had to call a halt to the countdown.
The failure of a 'fill and drain' valve in the Atlas 5 heavy-lift rocket also contributed to an initial delay. However, it later started working properly.
