In the face of unrelenting days of very poor weather and a range conflict with another very critical rocket launch, SpaceX is pushing back the return debut of their private Falcon 9 rocket carrying a revolutionary fleet of voice and data commercial communications relay satellites for Iridium to no earlier than next weekend, Jan 14.

Earlier indications of a nearly weeks long launch delay from Monday, Jan. 9 to next Saturday morning, Jan. 14, were officially confirmed today, Jan. 8, by SpaceX and their Iridium Communications customer.

“Launch moving due to high winds and rains at Vandenberg,” SpaceX announced today, Jan. 8.

Liftoff of the SpaceX Falcon 9 with the payload of 10 identical next generation Iridium NEXT communications satellites had been slated for 10:22 am PST (1:22 pm EST), Jan. 9, 2017 from Space Launch Complex 4E on Vandenberg Air Force Base in California.

And it was less than 48 hours ago on Friday, Jan. 6, that the FAA finally granted SpaceX a license to launch the ‘Return to Flight’ Falcon 9 mission – as I confirmed with the FAA here.

The private rocket – developed by CEO Elon Musk and his company – has been grounded for four months since a catastrophic launch pad explosion last September suddenly destroyed another Falcon 9 and its $200 million Israeli owned satellite during a prelaunch fueling test on the Florida Space Coast.

The prognosis of a week of bad California weather had been known for some time and finally prompted an official announcement just 24 hours before the hoped for launch.

“With high winds and rain in the forecast at Vandenberg Air Force Base, the first launch of 10 Iridium NEXT satellites is now planned for January 14th at 9:54:34 am PST with a back-up date of January 15th,” Iridium officials elaborated in a statement.

The mission, known as Iridium 1, has an instantaneous launch opportunity at 9:54:34 a.m. PST (12:54:34 p.m. EST).

Next Sunday, Jan. 15 is available as a back-up launch opportunity in case of a delay for any reason including technical and weather related issues
Furthermore, humorous pleas by Iridium CEO Matt Desch for divine intervention went unheeded !

“Can now confirm: new launch date Jan 14 at 9:54am pst. Bad weather the cause. Anti-rain dances didn’t work – oh well. Cal needs rain?” said Iridium CEO Matt Desch when he threw in the towel this morning by tweet.

Things change fast and furious in the rocket business, and flexibility is the name of the game if you want to survive the frequently changing landscape.

A contributing factor to the delay is a range conflict with an upcoming Atlas rocket launch for the U.S National Reconnaissance Organization (NRO) at Vandenberg AFB.

“Other range conflicts this week results in next available launch date being Jan 14,” SpaceX confirmed.

The United Launch Alliance Atlas V is scheduled to launch the super secret NROL-79 spy satellite for the NRO on Jan. 26.

Prior to the launch, ULA must conduct a wet dress rehearsal (WDR) of the Atlas V by fueling it with propellants to confirm its readiness to launch.

The clandestine NROL-79 intelligence-gathering payload is critical to US national defense. Surly it was manufactured over a time span of several years at an unknown classified cost probably amounting to billions of dollars.
