SpaceX launched one of its Dragon rockets this morning on a resupply mission to the International Space Station, ISS, but ran into problems nine minutes after liftoff.

SpaceX founder Elon Musk said three of the four thrusters did not ignite as planned.

Speaking from the company’s Hawthorne, CA mission control, Musk said he wants at least two of the four sets to kick in before the solar panels extended.

The rocket is due to arrive at the ISS carrying 1 ton of much-needed cargo, such as air purifiers and other maintenance gear.

SpaceX is a private venture that won a $1.6 billion NASA contract to resupply the ISS.

The Dragon capsule successfully reached orbit but then failed to ignite all of the thruster needed to put it on the correct trajectory to safely reach the ISS.

NASA’s mission control in Houston offered to assist, but so far SpaceX officials have said they believe they can remedy the situation.
