One of the three composite overwrapped pressure vessels (COPV) failed.
Ground crews planned to install the 10 satellites - built by Thales Alenia Space and Orbital ATK - on the Falcon 9 rocket inside SpaceX's hangar this weekend for a launch attempt next week.
However, space enthusiasts have been anxious for the lack of response from FAA despite the company's confidence it would definitely resume its operations this month.
Falcon 9 will have a liftoff from Vandenberg Air Force Base carrying 10 Iridium Communications satellites. "The FAA has granted a license for that goal".
The listing of launch schedules on Spaceflight Now also mentions January 9 as the date for the Falcon 9 launch, but does not specify a time.
The new rocket is confirmed to be launch on Monday as scheduled.
While NASA had cleared the company already, the FAA clearance came Friday, which grants SpaceX permission for seven launches of a Falcon 9 version 1.2 rocket, with the objective of placing in low Earth orbit a constellation of 10 Iridium NEXT satellites each.
CEO Elon Musk tweeted that all systems were go for the scheduled Sunday launch, but the Federal Aviation Administration said it has yet to issue a license for the launch.
All SpaceX launches were immediately grounded when their Falcon 9 booster and its $200 million AMOS-6 Israeli communications satellite payload were suddenly destroyed without warning during a routine preflight fueling test on September 1, 2016, at pad 40 on Cape Canaveral Air Force Station in Florida. A hold-down firing, SpaceX representative John Taylor explained, is a pre-launch test where engines are operated at full thrust to make sure the rocket is in good shape.
The FAA announced that it approved the launch license today, which is actually for seven launches from SLC-4E, each delivering 10 Iridium NEXT satellites to orbit.
SpaceX has a major announcement for everyone who has been trying to understand why a rocket exploded on its launch pad in Florida previous year: they finally have a cause.
The company had to face many issues like figuring out the cause of the launch failure, finding a solution to it, ensuring that it didn't happen again etc.
SpaceX officials said the helium pressurant will be loaded at warmer temperatures in future countdowns to prevent buckling of the tank's aluminum liner.
