SpaceX’s 1st launch since rocket blast now bumped to January

The Iridium NEXT constellation will replace the world’s largest commercial satellite network of low-earth orbit satellites, Iridium Communications Inc has said. Billionaire Elon Musk’s company announced Wednesday that it plans to return to space in January, after last week saying December, but the FAA has yet to grant SpaceX the required license, Wired reported Wednesday. The condosat is scheduled to be launched from the Guiana Space Center in Kourou, French Guiana in mid-2017.

The Falcon 9’s first stage came back to land at Cape Canaveral after that launch, the first time a rocket ever accomplished such a landing.

Musk, who is also the CEO of electric auto company Tesla Motors tsla , told CNBC in November that the explosion was unlike anything ever “encountered before in the history of rocketry”.

SpaceX has been working with the FAA, NASA, the US Air Force and industry experts to investigate why the Falco 9 rocket exploded on the launch pad in Cape Canaveral.

The company traced the explosion to a fueling system problem that caused a pressurized container of helium inside the rocket’s upper stage to burst.

That explosion destroyed a $200 million Israeli communications satellite. “Inmarsat is a long-time partner, and we wish them well with their upcoming mission”.

After repeatedly telling customers and journalists it was confident of resuming rocket launches in 2016, Elon Musk’s Space Exploration Technologies Corp. has pushed that timetable to January.

British satellite telecommunications company Inmarsat has confirmed that it has switched a launch from SpaceX to Arianespace. Its mid-December launch target has been delayed, though. SpaceX, on the other hand, was able to relaunch its Falcon 9 rocket within just 6 months after its June 2015 accident.

However, it’s unlikely that SpaceX will cut back on its ambitions anytime soon.

Inmarsat will launch Inmarsat-5 F4, a Global Xpress (GX) satellite, with SpaceX.

Two of the satellites were supposed to lift off on a Russian-Ukrainian Dnepr rocket, a modified Soviet-era nuclear missile, but that program’s future is in doubt.

The company said Wednesday it needs more time.
