SpaceX said it was "optimistic" Friday after a thruster outage delayed the latest resupply mission of its unmanned Dragon capsule en route to the International Space Station.
SpaceX and NASA officials said the cargo resupply mission was still on track, but the technical mishap could fuel concerns about the US agency's ambitious plans to cut costs by privatizing elements of the space program.
SpaceX's billionaire founder Elon Musk said the failure of three out of four thruster pods to fire up was a "little frightening" but that two pods were back online within a few hours and the others should be working again shortly.
"I'm optimistic that we will be able to turn all four thruster pods on and restore full control," he told reporters.
Musk later tweeted: "Thruster pods one through four are now operating nominally. Preparing to raise orbit. All systems green."
SpaceX and NASA officials said once the pods are back online, they would carry out a number of checks before clearing the vessel to dock at the space station in the coming days, perhaps as early as Sunday.
The original rendezvous had been planned for 1130 GMT Saturday, but Mike Suffredini, NASA program manager for the International Space Station, said there was "quite a bit of flexibility" in the berthing date.
