After missing its scheduled rendezvous with the International Space Station, NASA's freight transportation company, Space Exploration Technologies says it is back on track, with all four of its cargo capsule's rocket thruster pods working.
The first order of business was to raise Dragon's orbit to prevent it from being pulled back into Earth's atmosphere in a couple of days.
"Orbit raising burn successful. Dragon back on track," company founder and chief executive Elon Musk posted on Twitter seven hours after a Falcon 9 rocket blasted off from Cape Canaveral Air Force Station in Florida on the firm's second cargo run for NASA.

Shortly after the Falcon deposited Dragon into orbit, engineers discovered three of the capsule's four thruster pods weren't working properly. Preliminary analysis points to a possible problem with a blockage in a pressurization system or a faulty valve, Musk told reporters on a conference call Friday afternoon.
His confidence that the problem would be fixed appeared to be well-placed, with all four thrusters back in operation Friday evening.
