That would mean a second launch no earlier than December, at the earliest. Desch said Iridium’s goal of having all Iridium Next satellites in service by the end of 2017 would be a challenge but was still feasible. - See more at: http://spacenews.com/iridiums-sp ... thash.F7lZ2saK.dpuf

The creditors and Iridium’s insurance underwriters had also asked that the first batch of satellites be tested for three months in orbit before a second batch was launched, to verify their design and performance. - See more at: http://spacenews.com/iridiums-sp ... thash.F7lZ2saK.dpuf

As the Russian/Ukraine Dnepr and corresponding launch services can no longer be provided by the International Space Company Kosmotras (ISCK), the joint NASA-GFZ Joint Steering Group has decided to exchange the GRACE-FO launcher. The corresponding contract was signed on 14. November 2016 by the Board of GFZ and Iridium Satellite LLC. It stipulates a "Rideshare" between GRACE-FO and 5 Iridium-Next satellites on a Space-X Falcon-9 from Vandenberg Air Force Base in California within the launch period December 2017 till February 2018. This also includes a contract with Airbus D&S who will build the necessary Multi Satellite Dispenser and will perform the Launch Service Management under contract of GFZ.

Iridium says the launch of its next ten satellites will slip to mid-June because of a backlog in SpaceX’s manifest: http://bit.ly/2kpGL5S

Working alongside mission partners, members of the 30th Space Wing’s safety office have quietly put in numerous hours ensuring the safe and successful utilization of a system known as an Autonomous Flight Safety System. The AFSS is a device that is placed on the rocket and collects a variety of essential data from the vehicle during flight. This data is then used to determine if the rocket is maintaining a safe flight or if termination is required.

With 30th safety personnel ensuring the smooth integration of the system, SpaceX’s CRS-10 mission to resupply the International Space Station, on Feb. 19, marked the first time the system was actively used to protect public safety.

“Autonomous Flight Safety Systems have been flown on various launch vehicles but only as a ride along, meaning they are not actively controlling the vehicle’s termination system,” said Kevin Case, 30th SW range safety engineer. “SpaceX has flown various versions of the AFSS system to refine their design and processes for autonomous launches. SpaceX’s CRS-10 mission was the first launch actively utilizing the AFSS to protect public safety.”

Although the CRS-10 mission did not launch from Vandenberg, members of the 30th safety office were instrumental to the development and deployment of this revolutionary new capability.

“Safety supported multiple engineering test flights and risk reductions flights that served as a path finder for the first operational use of AFSS on the Falcon 9 CRS-10 launch from the Eastern Range,” said Jay Reid, 30th SW safety office flight analyst and aerospace engineer. “Safety’s support included developing a (Mission Data Load) for each flight and analyzing the data collected following the launch. This effort allowed both ranges to gain confidence in AFSS and refine the rules and processes used to support CRS-10. Safety’s involvement in the engineering test flights and risk reduction flight was crucial in the development and approval of a standard set of rules and processes for Falcon 9 AFSS missions from both ranges. Without this effort, the Western Range would not be ready to support their first AFSS launch planned for this summer.”

As opposed to the currently commonplace system of a highly trained, human operator, known as a Mission Flight Control Officer, giving the order to destruct – the AFSS streamlines the determination to destruct in the event of a safety risk.

“Conventional flight termination systems use tracking data to display the launch vehicle’s status to a Mission Flight Control Officer,” said Case. “The Mission Flight Control Officer evaluates vehicle performance compared to the planned trajectory and protection zones. If the vehicle violates these rules or zones, the Mission Flight Control Officer issues an arm and destruct command dispersing vehicle propellants to render the vehicle non-propulsive and containing resultant debris within a controlled area. The Autonomous Flight Safety System uses onboard sensor data to evaluate vehicle performance against a set of predefined mission rules.”

The CRS-10 mission is expected to be just the beginning of the mechanism’s implementation, and experts believe the demand for the automated system will steadily grow with the continued support of the 30th safety team.

“Range users are interested in AFSS based on the Core Autonomous Safety Software, as the CASS provides the logic for evaluating mission rules and computing a safety recommendation to the host system for action, and SpaceX is the first to fly the system operationally,” said Case. “There are several other programs currently working with the 30th SW, 45th SW, and FAA to design, test and deploy AFSS based on CASS for use on their launch vehicles. Autonomous flight termination will continue to grow as more are fielded and knowledge of the system’s capability and flexibility grows.”

Four of the 10 first Iridium Next satellites launched in January by SpaceX carry AIS payloads for exactEarth. The company said April 6 that it expected them to enter service by the end of May.

A second Iridium 10-satellite launch by SpaceX is scheduled for June. Nine of these satellites carry AIS gear. The remaining 47 Iridium Next satellites are scheduled for launch in 2017 and early 2018, assuming that SpaceX can meet its aggressive 2017 launch-cadence schedule.https://www.spaceintelreport.com/maritime-tracker-exactearth-cuts-costs-awaits-iridium-fleet-deployment

MCLEAN, Va., May 25, 2017 (GLOBE NEWSWIRE) -- Iridium Communications (NASDAQ:IRDM) today announced the second launch for the Iridium NEXT satellite constellation has been moved earlier, and is now targeted for June 25, 2017 at 1:24:59 pm PDT with an instantaneous launch window.  SpaceX informed Iridium that range availability had opened up at Vandenberg Air Force Base (VAFB) in California, where SpaceX's west coast launch facility is located, and planned to target Iridium's launch four days earlier than originally scheduled. This launch will deliver the second payload of 10 Iridium NEXT satellites to orbit, bringing the total to 20 Iridium NEXT satellites in space.

"We're excited for this next launch," said Matt Desch, chief executive officer, Iridium. "Satellites have already started to arrive at the launch site and are undergoing pre-launch preparations, so we'll be ready to go.  An earlier launch date is all the better for our constellation deployment plans."   

Iridium has partnered with SpaceX for a series of eight launches scheduled to take place through mid-2018, delivering a total of 75 satellites to low-Earth orbit. Iridium NEXT is replacing the Company's existing constellation of satellites with more powerful capabilities, including Aireon's space-based global real-time aircraft surveillance and tracking service.

Not only onsite, but now all mated to dispenser!  We're on schedule for fueling this weekend.  T-minus 18 days and counting to L2!
