High winds in Florida have pushed to Sunday Orbital ATK's launch of its unmanned Cygnus cargo ship to the International Space Station, the latest in a series of delays due to weather.
The next launch bid will commence at 4:44 pm (2144 GMT) on Sunday, with the opening of a 30-minute launch window, NASA said.
Strong winds moreover delayed Friday's attempt, & rainy weather postponed the initial launch bid on Thursday.
Orbital has a $1.9 billion contract with NASA to supply astronauts at the orbiting outpost yet has not sent any cargo in more than a year because of an Antares rocket explosion in October 2014 that destroyed its cargo ship & the thousands of pounds of supplies on board.
The accident was blamed on a failure in the decades-old Ukrainian-made engine, which had been reconditioned for use.
This time, Orbital ATK is relying on an Atlas V rocket made by United Launch Alliance to propel the cargo ship to low-Earth orbit.
The cargo ship is loaded with 7,300 pounds (3,300 kilograms) of food, science experiments, & other supplies.
