SpaceX's Falcon 9 rocket blasted off Friday to send an unmanned Dragon cargo capsule on its quickest trip yet to the International Space Station, but the company reported a problem with the Dragon in orbit.
The Falcon 9 made a problem-free ascent from its launch pad at Cape Canaveral Air Force Station in Florida at 10:10 a.m. ET. Then, minutes after launch, the company's billionaire founder, Elon Musk, reported in a Twitter update that controllers were looking into a technical issue involving the capsule.
"Issue with Dragon thruster pods," Musk wrote. "System inhibiting three of four [pods] from initializing. About to command inhibit override."
It was not clear whether other issues might have arisen; speculation centered on whether the Dragon's power-generating solar arrays were properly deployed. A news briefing is to be conducted at 11 a.m. ET to discuss the status of what's expected to be a three-week resupply mission.
