Orbital Sciences says it will likely stop using the type of engines that were employed when its unmanned Antares commercial supply rocket bound for the International Space Station exploded moments after liftoff last week.

Though a strong solar storm interfered with the latest grocery run to the space station, the good news is the orbiting lab has won a 4-year extension to 2024.

NASA said it is not yet known whether or not a space walk will be needed to repair a faulty coolant pump aboard the ISS, but they continue to investigate.
