The first 10 satellites in Iridium's next-generation mobile voice and data network could head into orbit from California as soon as Dec. 16 on SpaceX's first Falcon 9 flight since a booster exploded on its launch pad at Cape Canaveral in September, grounding the commercial launcher more than three months.
Iridium said Thursday that the launch from Vandenberg Air Force Base in California is scheduled for Dec. 16 at 12:36 p.m. PST (3:36 p.m. EST; 2036 GMT), pending regulatory approval from the Federal Aviation Administration, the agency responsible for overseeing commercial space launches.
SpaceX has not launched a rocket since a Falcon 9 exploded during a prelaunch test at Cape Canaveral on Sept. 1, destroying the launcher and the Israeli-owned Amos 6 communications satellite on-board, and damaging the company's primary East Coast launch facility.
Near-term Falcon 9 missions will blast off from Vandenberg and launch pad 39A at Kennedy Space Center, a former space shuttle facility which SpaceX leases from NASA and is modifying for Falcon 9, Falcon Heavy, and crewed flights.
The launch of the first 10 Iridium Next satellites was next on SpaceX's manifest after the doomed Amos 6 mission, and it remains first in line after the company's schedule shuffled in the wake of the Sept. 1 pad explosion.
The 10 satellites were delivered two-at-a-time to Vandenberg from their Orbital ATK factory in Gilbert, Arizona, in August for a planned launch in mid-September. Preparations were halted after the launch pad accident at Cape Canaveral.
Work has resumed inside SpaceX's clean room at Vandenberg, with the final steps before launch including the attachment of all 10 spacecraft — designed by Thales Alenia Space and built in partnership with Orbital ATK — to a SpaceX-provided dispenser.
The deployment mechanism has two tiers, each holding five of the satellites. Once technicians connect the craft to the dispenser, they will load hydrazine fuel into each satellite. The spacecraft will each weigh nearly 1,900 pounds — about 860 kilograms — with a full tank of propellant.

Then the satellites will be encapsulated inside the Falcon 9's payload fairing, and connected to the two-stage rocket inside the horizontal integration hangar near Space Launch Complex 4-East.
But first, SpaceX plans to run the Falcon 9 through a customary preflight static fire test, the same procedure that resulted in the explosion at Cape Canaveral in September. Iridium officials have said they will not put their satellites on the Falcon 9 rocket until the static fire test, which includes fueling of the booster and a brief on-pad engine firing, is successfully completed.
The Falcon 9 rocket will place the first 10 next-generation communications satellites into a polar orbit around 388 miles (625 kilometers) above Earth. From there, the satellites will use on-board thrusters to maneuver into their final positions in the Iridium constellation.
"We're excited to launch the first batch of our new satellite constellation. We have remained confident in SpaceX's ability as a launch partner throughout the Falcon 9 investigation," said Matt Desch, chief executive officer at Iridium. "We are grateful for their transparency and hard work to plan for their return to flight.  We are looking forward to the inaugural launch of Iridium Next, and what will begin a new chapter in our history."
SpaceX will launch 70 Iridium Next satellites aboard 10 Falcon 9 missions from Vandenberg under a contract signed between the companies in 2010.
Thales Alenia Space and Orbital ATK are manufacturing 81 satellites for Iridium, which is still discussing launch options for the remaining 11 spacecraft.
"We are looking forward to return to flight with the first Iridium Next launch," said Gwynne Shotwell, president and chief operating officer of SpaceX. "Iridium has been a great partner for nearly a decade, and we appreciate their working with us to put their first 10 Iridium Next satellites into orbit."
The launch delay caused by the grounding of the Falcon 9 rocket will mean the Iridium Next constellation will not be fully deployed until at least early 2018, a few months later than Iridium's long-standing goal of having the satellites all in orbit by the end of 2017.

SpaceX founder and chief executive Elon Musk told CNBC last month that investigators believe they have narrowed the likely cause of the Sept. 1 mishap to a problem during filling of the rocket's second stage with super-cold liquid oxygen.
The explosion occurred about eight minutes before the Falcon 9's engines were to ignite during a hold-down test.
The oxygen likely froze solid and caused a high-pressure helium tank to burst, blowing the upper stage apart almost instantly, and leading the rest of the rocket to collapse in a fireball. The helium is used to pressurize the second stage's propellant tanks for flight.
Musk said engineers believe they can fix the problem with a change in fueling procedures, avoiding major hardware changes that would have kept SpaceX missions grounded longer.
The explosion was the second loss of a Falcon 9 mission, coming just over a year after a rocket disintegrated about two minutes after liftoff in June 2015 with a Dragon supply ship heading for the International Space Station.
Meanwhile, SpaceX is completing upgrades to launch pad 39A in Florida to resume launches there as soon as early January.
The EchoStar 23 communications satellite, a geostationary platform made by Space Systems/Loral, is scheduled for liftoff from pad 39A as soon as Jan. 8 to begin a mission beaming direct-to-home television programming over Brazil.
After EchoStar 23's launch, SpaceX is readying its next Dragon cargo mission to the space station for a liftoff that could occur by the end of January, along with the first launch of a previously-flown Falcon 9 first stage booster with the SES 10 communications satellite in January or February.
The order of SpaceX launches after EchoStar 23 remains undecided.

The first 10 satellites for Iridium's next-generation mobile voice and data relay network have been fueled, joined with their deployment module and encapsulated inside the clamshell-like nose cone of a SpaceX Falcon 9 booster for launch as soon as next week from Vandenberg Air Force Base in California.
SpaceX and Iridium have not announced a target launch date, but engineers are aiming to have the mission ready for liftoff by Jan. 7. That schedule is still very preliminary.
An official target launch date is pending the Federal Aviation Administration's approval of the SpaceX-led investigation into the explosion of a Falcon 9 rocket on a launch pad at Cape Canaveral on Sept. 1, which destroyed the Israeli-owned Amos 6 communications satellite awaiting liftoff a few days later.
SpaceX missions have been grounded since the explosion. The California-based launch company, founded and headed by Elon Musk, hoped to resume launch services by the end of 2016, but the investigation, launch preparations, and the FAA's review of the Sept. 1 mishap pushed the Falcon 9's return-to-flight into January.
The launch of Iridium's first 10 next-generation communications satellites, the first part of an eventual network of 81 spacecraft, was next in line on SpaceX's manifest at the time of the Sept. 1 explosion.
Meanwhile, construction crews at Kennedy Space Center's launch pad 39A in Florida are finishing up modifications to the former space shuttle launch complex to support Falcon 9 flights as soon as late next month.
The launch facility used by SpaceX's previous missions from Cape Canaveral, Complex 40, suffered major damage after the Sept. 1 rocket explosion, the first such on-the-ground mishap at the Florida spaceport since the early years of the Space Age.
All of SpaceX's near-term launches from Florida will take off from pad 39A.
But the launch for Iridium from California's Central Coast is first in line as final preparations are nearing completion inside SpaceX's hangar at Space Launch Complex 4-East, a hillside facility overlooking the Pacific Ocean.

Within the last week, technicians from satellite-builders Thales Alenia Space and Orbital ATK have filled all 10 "Iridium Next" satellites with hydrazine fuel used to maneuver the spacecraft once in orbit.
The satellites are mounted on a deployment module developed by SpaceX specifically for the Iridium missions to be flown on Falcon 9 rockets. SpaceX is under contract to launch at least 70 Iridium Next satellites through early 2018, primarily in batches of 10 at a time.
Launch arrangements for the remaining Iridium Next satellites, which are built as spares, have not been announced.
The mounting system is made up of two tiers, each holding five satellites. Ground crews inside the SpaceX payload processing facility at Vandenberg have stacked the two tiers and encapsulated the satellites inside the Falcon 9's payload fairing, which is emblazoned with the Iridium logo.
After the Falcon 9 rocket completes its pre-flight "static fire" test on the launch pad — the same test that resulted in the explosion in Florida on Sept. 1 — the 10 Iridium Next satellites will be mated with the booster for liftoff.

Once the Falcon 9's second stage reaches a polar orbit around 388 miles (625 kilometers) above Earth, the 10 signals relay stations will separate from the deployment module to begin three months of tests to check the health and function of spacecraft systems, ground and inter-satellite communications links, and tack-on instruments to track global air and maritime traffic.
The satellites will maneuver into the operational Iridium constellation at an altitude of 485 miles (780 kilometers), replacing the company's 66 existing satellites one-by-one.
One of the Iridium Next launches in the fourth quarter of 2017 will only carry five Iridium Next satellites. The rest of the Falcon 9's lift capacity will be taken up by two U.S.-German gravity research spacecraft, a follow up to the Gravity Recovery and Climate Experiment, or GRACE, satellites launched in 2002.
The GRACE-Follow-On mission was supposed to launch on a Russian-Ukrainian Dnepr rocket, but that program's future is in doubt in the wake of Russia's annexation of Crimea and military activity in eastern Ukraine. Russian officials have said they plan to discontinue Dnepr launches.
Managers from the German Research Center for Geosciences in Potsdam, or GFZ, switched the GRACE-FO mission to a Falcon 9 rocket launch. The German research center is partnering with NASA on the mission.
The Iridium Next launch in early January will mark the third Falcon 9 mission from the West Coast complex, and the 29th Falcon 9 launch overall since SpaceX's workhorse booster debuted in June 2010. One of the Falcon 9 flights is counted as a failure, not including the vehicle lost on the launch pad Sept. 1.
SpaceX founder and chief executive Elon Musk told CNBC last month that investigators believe they have narrowed the likely cause of the Sept. 1 mishap to a problem during filling of the rocket's second stage with super-cold liquid oxygen.
The explosion occurred about eight minutes before the Falcon 9's engines were to ignite during a hold-down test.

The upcoming launch is a big step for Iridium, which is spending $3 billion on the new satellite program. Iridium's current satellite network is aging — the old spacecraft launched between 1997 and 2002 — and needs an upgrade.
"There were many challenges on the program, from orbit determination knowledge design, to encryption design, to integration and verification test planning, to planning for on orbit acceptance activities, but the team made it all come together and the satellites are ready for deployment to enhance the future of mobile satellite communications — I could not be more proud," said Joel Rademacher, director of systems engineering for the Iridium Next program.
With a full load of propellant, each satellite weighs nearly 1,900 pounds (860 kilograms), and when combined with the specially-designed multi-spacecraft mounting dispenser, the Iridium Next package will be weigh in at more than 20,000 pounds, the heaviest payload launched by SpaceX to date.
SpaceX intends to recover the Falcon 9's first stage booster on a barge positioned south of Vandenberg in the Pacific Ocean, a continuation of the company's efforts to master vertical rocket landings and reusability.

After an exhaustive investigation, SpaceX engineers have identified the most likely cause of the spectacular explosion of a Falcon 9 rocket during a pre-launch test Sept. 1 that destroyed the booster and its $195 million satellite payload, the company announced Monday.
SpaceX engineers believe the Cape Canaveral Air Force Station mishap was triggered by the failure of a high-pressure helium tank, one of three used to pressurize the second stage liquid oxygen tank.
Putting corrective actions in place, the company said Monday it plans to resume flights with a launch from Vandenberg Air Force Base northwest of Los Angeles on Jan. 8 to boost 10 Iridium NEXT satellite telephone relay stations into orbit.
It is not yet known when SpaceX plans to resume flights from Cape Canaveral. Launch complex 40 at the Florida Air Force station was heavily damaged in the Sept. 1 mishap, and the company plans to use a repurposed space shuttle launch pad at the nearby Kennedy Space Center for its next Falcon 9 flight from Florida.
Sources indicate the first flight from Kennedy will be another commercial mission. The next SpaceX flight to deliver cargo to the International Space Station, the company's 10th under contract to NASA, is expected to take place some time after the commercial mission.
SpaceX's Falcon 9 rocket uses super-cooled, or "densified," liquid oxygen and RP-1 kerosene fuel to provide additional performance during ascent. To achieve and maintain the desired low temperatures, propellant loading begins just 35 minutes before launch.
To push propellants to the rocket's engines, the Falcon 9 uses highly pressurized helium stored in aluminum bottles, wrapped in a tough, insulating carbon composite material. The bottles, known as composite overwrap pressure vessels, or COPVs, are mounted inside the propellant tanks, submerged in frigid liquid oxygen and chilled kerosene.

Спойлер

On Sept. 1, about five minutes before a planned test firing of the Falcon's nine Merlin 1D first stage engines — a routine pre-launch test for SpaceX — the second stage suddenly exploded in a spectacular conflagration that was caught on video and widely seen around the world.
The rocket and it's $195 million payload, a commercial communications satellite, were destroyed, causing heavy damage to launch complex 40 at the Cape Canaveral Air Force Station. Just 93 milliseconds elapsed from the first signs of trouble to the explosion.
"Investigators scoured more than 3,000 channels of video and telemetry data covering a very brief timeline of events," SpaceX said in a statement posted to its website. "Because the failure occurred on the ground, investigators were also able to review umbilical data, ground-based video, and physical debris.
"To validate investigation analysis and findings, SpaceX conducted a wide range of tests at its facilities in Hawthorne, California and McGregor, Texas."
SpaceX is generally tight-lipped when it comes to technical details, and the statement posted Monday provided only a general overview of the team's findings. It said accident investigators "concluded that one of the three composite overwrapped pressure vessels (COPVs) inside the second stage liquid oxygen (LOX) tank failed."
"Specifically, the investigation team concluded the failure was likely due to the accumulation of oxygen between the COPV liner and overwrap in a void or a buckle in the liner," the company said.
Investigators believe those extremely low temperatures may have caused some of that trapped oxygen to solidify. In any case, when the tank was pressurized, trapped oxygen pushing against the carbon overwrap fibers likely generated friction "leading to ignition and the subsequent failure of the COPV."
Liquid oxygen has a temperature of around minus 298 degrees Fahrenheit, but SpaceX chills the propellant to around minus 340 degrees for use aboard the Falcon 9. The RP-1 kerosene fuel, which normally is stored at a room temperature 70 degrees, also is chilled. The lower temperatures increase the propellants' density.
A rocket engine's thrust is directly proportional to the rate propellants are consumed and expelled. By "densifying" the Falcon 9 propellants, more fuel can be stored and pumped through the engines, increasing performance.
While earlier rockets, including the Titan 2 booster used to launch NASA's Gemini spacecraft in the 1960s, used propellant cooling to increase density, and thus engine performance, the upgraded Falcon 9 is believed to be the first utilizing super-cooled cryogenic oxygen.
SpaceX founder Elon Musk said in 2015, when propellant cooling was first implemented in the Falcon 9, that "we're sub-cooling the propellant, particularly the liquid oxygen, close to its freezing point, which increases the density quite significantly."
Failure investigators "identified several credible causes for the COPV failure, all of which involve accumulation of super chilled LOX or SOX (solidified oxygen) in buckles under the overwrap," the company said in its statement.
"The corrective actions address all credible causes and focus on changes which avoid the conditions that led to these credible causes. In the short term, this entails changing the COPV configuration to allow warmer temperature helium to be loaded, as well as returning helium loading operations to a prior flight proven configuration based on operations used in over 700 successful COPV loads."
The company did not provide any details about those earlier helium loading procedures but said it plans to redesign the helium bottles in the long term "to prevent buckles altogether, which will allow for faster loading operations."
The Sept. 1 failure was the second involving the Falcon 9's second-stage helium pressurization system.
During a June 2015 launch to deliver supplies to the space station, a strut holding a second-stage helium tank in place inside the liquid oxygen tank failed, allowing the helium bottle to shoot up and crash into the top of the oxygen tank, triggering a catastrophic rupture.
It was SpaceX's first outright Falcon 9 failure in 19 launchings dating back to the rocket's maiden flight in June 2010. After taking steps to ensure all internal struts met design specifications, SpaceX launched nine successful missions in a row before the Sept. 1 launch pad disaster, all of them using densified propellants.

The return to flight for the Falcon 9 rocket will wait at least a day longer at Vandenberg Air Force Base. (http://www.vandenberg.af.mil)
The Space Exploration Technologies (http://www.spacex.com) rocket launch has been postponed until at least Monday, one day later than initially planned. 
While officials announced at the start of week their plans to aim for a 10:28 a.m. Sunday departure, (https://www.noozhawk.com/article/spacex_falcon_rocket_aims_for_sunday_return_to_flight_at_vandenberg_afb) notices warning boaters and pilots of an upcoming launch now say the mission is targeting Monday, Jan. 9.
The one-day delay means the launch time is expected to be a few minutes earlier to ensure the satellites are placed where needed in space.
As a precaution before each launch, Vandenberg sends out notices to mariners and pilots about areas to avoid due to a rocket launch or missile test from the base. 
The one-day slip comes as SpaceX crews attempt to conduct a countdown rehearsal and engine test firing at Vandenberg.
During the test, the engines will ignite before turning off seconds later, while the rocket remains anchored to the launch pad.
That test reportedly was planned for Tuesday, according to employee posts on Internet forums, but had not occurred. 
During a similar test Sept. 1 in Florida (https://www.noozhawk.com/article/spacex_rocket_explosion_in_florida_likely_to_delay_vandenberg_afb_launch), a flaw in the design led to an explosion of the rocket that destroyed its payload.
Since then, engineers have been sifting through data to pinpoint the likely cause of this mishap.
On Jan. 2, officials announced the results of the failure review, short- and long-term fixes and the planned Sunday launch attempt, although the mission still needs Federal Aviation Administration  (http://www.faa.gov)approval. 
"The FAA has received the mishap investigation report from SpaceX and it is under review," Hank Price, spokesman for the FAA's Office of Commercial Space Transportation,  (https://www.faa.gov/about/office_org/headquarters_offices/ast/)said Wednesday. "The FAA continues to work closely with SpaceX as they conduct the investigation and prepare for future Falcon 9 launches, in compliance with all applicable regulations and license requirements.
 "The FAA has not yet issued a license to SpaceX for a launch in January," Price added.
The Falcon rocket will carry 10 Iridium Next (http://www.iridium.com) satellites, the first set for a second-generation constellation of craft for the satellite-phone system.

In the short term, this entails changing the COPV configuration to allow warmer temperature helium to be loaded, as well as returning helium loading operations to a prior flight proven configuration based on operations used in over 700 successful COPV loads. In the long term, SpaceX will implement design changes to the COPVs to prevent buckles altogether, which will allow for faster loading operations.​

Интересно, чем изменение конфигурации COPV отличается от изменения конструкции COPV?

Per the Twitter rumors, SpaceX's new launch date for Falcon 9/Iridium is NET January 14. Not official as SpaceX or Iridium need to say it.

By Janene Scully, Noozhawk North County Editor | @JaneneScully (http://twitter.com/JaneneScully) | (https://img.novosti-kosmonavtiki.ru/209369.gif) 6:37 p.m. | January 7, 2017 | 2:05 p.m.
                                                 
Despite having a Federal Aviation Administration (http://www.faa.gov) license in hand and an on-pad test complete, a Falcon 9 rocket (http://www.spacex.com/falcon9) and its cargo still will have to wait several days longer for the launch  from Vandenberg Air Force Base (http://www.vandenberg.af.mil).
Liftoff of the Space Exploration Technologies (http://www.spacex.com) rocket now is planned for Jan. 14 from Space Launch Complex-4 (https://en.wikipedia.org/wiki/Vandenberg_AFB_Space_Launch_Complex_4) on South Base, according to safety notices revised Saturday evening.
Reasons for the delay aren't known, but weather-related postponements typically don't occur more than 24 hours before liftoff. The team likely is battling other issues that can involve the technical troubles with a rocket, satellites or ground support equipment or even scheduling conflicts with other activities at Vandenberg.
Even if they are tackling technical troubles, the weather looked less than accommodating for a Monday launch attempt, however, as heavy rains are expected with an incoming winter storm.
Rainy conditions are expected for most of the week, with Saturday hinting at one of the best chances for sunshine, according to the National Weather Service (http://forecast.weather.gov/MapClick.php?CityName=Lompoc&state=CA&site=LOX&textField1=34.6392&textField2=-120.457&e=0#.WHGuS4nQeqA).
While many launches have longer windows that offer multiple chances to get off the ground, this mission has just one moment a day so the Iridium (https://www.iridium.com) satellites can be placed in the proper place in space. The launch moves several minutes early for each day it delays.
Since late Friday, other signs hinted that a Monday attempt appeared shaky. ​Vandenberg officials did not release information about the upcoming launch as they typically do. 
As of Friday morning, Iridium officials were hopeful for a Monday attempt
"Looks like we're good to go for Monday!" Iridium CEO Matt Desch said on his Twitter account (https://twitter.com/IridiumBoss). "Payload/rocket mating underway; we'll just have to see about the weather. Anti-rain dances, anyone?"
The Falcon will carry the first 10 Iridium NEXT satellites (https://www.iridium.com/network/iridiumnext) to begin building the second-generation constellation of craft for the space-based phone system.
"The finish line of the marathon is in sight," said Scott Smith, Iridium chief operating officer. "The satellites are ready. The rocket is ready. Operations is ready. A new era is about to begin!"
On Friday, a day after the successful test of the rocket's engines, the FAA Office of Commercial Space Transportation (https://www.faa.gov/about/office_org/headquarters_offices/ast/) issued a license for the Falcon 9 rocket and six others for Iridium Communications.
"With completion of the static fire test, our first launch has just gotten that much closer," Desch said.
"The Iridium team has been anxiously awaiting launch day, and we're now all the more excited to send those first 10 Iridium Next satellites into orbit."
The license came after the FAA accepted the investigation report on the dramatic Sept. 1 mishap in which a Falcon erupted into a fireball during an on-pad test in Florida.
In what is expected to be a first for the West Coast, SpaceX plans to possibly land the Falcon rocket's first stage on a barge off the coast, according to the FAA license, which also mentions an ocean landing option.
SpaceX has conducted several flyback missions as part of Florida launches after the Falcon fulfilled the rocket's primary mission.
Unlike landlines and cell phones, the Iridium system provides coverage over 100 percent of the earth's surface, including across oceans, airways and polar regions, company representatives said.
The revolutionary system launched a majority of its original satellites plus several spares from Vandenberg aboard Delta II rockets (http://www.ulalaunch.com/products_deltaii.aspx) between 1997 and 2002.
The campaign meant jobs for the launch crews plus full hotels and restaurants when support staff and visitors came to watch the blastoffs.
Other Iridium satellites headed to space aboard Chinese and Russian launchers.
The system is named for the 77th chemical element on the Periodic Table (https://en.wikipedia.org/wiki/Periodic_table) —marking the original number of craft planned for the constellation.
While design changes meant fewer satellites for the constellation, the moniker remained.
Falcon rocket launches from Vandenberg can be viewed from various viewing sites around the Lompoc Valley since the launch pad is visible south of West Ocean Avenue (Highway 246).

Eight of Iridium's first ten upgraded communications satellites launched in January started providing voice and data relay service ahead of schedule, and SpaceX says it can launch up to 40 more Iridium spacecraft by the end of the year, Iridium officials reported Thursday.

Спойлер

"I'm happy to report that our initial batch of Iridium Next satellites are now fully operational and working very well," said Matt Desch, CEO of Virginia-based of Iridium Communications.

Engineers are repositioning the other two new-generation Iridium spacecraft in orbit to replace other satellites, part of a "highly-choreographed process" to complete a refresh of the company's entire constellation by mid-2018, Desch said Thursday in a quarterly earnings call with investment analysts.

The first eight Iridium Next satellites entered service in March and early April, taking the place of aging first-generation spacecraft launched in the late 1990s.

After their deployment from the second stage of a SpaceX Falcon 9 rocket launched from Vandenberg Air Force Base in California, the satellites boosted their altitude from a 388-mile-high (625-kilometer) drop-off orbit into the operational constellation at an altitude of 485 miles (780 kilometers) alongside the craft they were intended to replace.

Ground controllers then instantaneously switched off the inter-satellite communications links on the old satellite and turned on the links on the new craft, a procedure Iridium calls a slot swap.

The Iridium fleet consists of 66 operational satellites distributed in six orbital tracks, with 11 slots in each plane. The remaining two Iridium Next satellites deployed into Plane 6 on Jan. 14 are drifting into a different plane, a movement that will take around 10 months.

"We completed the commissioning of these Iridium Next satellites about one week ahead of schedule, which is a real testament to the planning and preparation of our satellite operations team," Desch said. "What's important is that our experience with in-orbit testing, slot swaps and the new satellite performance gives us confidence that we'll be able to manage the roughly 60-day launch cycle (we're) targeting following the second launch."

Iridium Announces Successful Completion of First-Launch Iridium NEXT Satellites Activities and Second Launch Date

Next-Generation Satellites are Actively Serving Iridium® Network Customers, While the Company Prepares for the Second Launch

MCLEAN, Va., May 02, 2017 (GLOBE NEWSWIRE) -- Iridium Communications Inc. (NASDAQ:IRDM), the only communications company with 100 percent global coverage, has announced that the first set of Iridium NEXT (https://www.globenewswire.comtracker?data=IlhEtqxoL5YPqctfECBL8nmKjxQ6VJxGfLgvkBLI21toGg-6tqJTgQVKUTlXhViIZi5J9D0kmRcte_8XE717ZQ==) satellites have been integrated into the operational constellation and are providing excellent service to Iridium customers. Prior to achieving this major program milestone, the new satellites went through a rigorous testing and validation process that demonstrated that they met all performance requirements and even exceeded many. The Iridium NEXT satellites are already providing superior call quality and faster data speeds with increased capacity to Iridium customers.  ...

The testing and validation process for the Iridium NEXT satellite constellation involved a thorough test of each of Iridium's services, an assessment of each satellite's performance against established metrics, and a formal acceptance process between Iridium and Thales, thus ensuring a smooth integration into Iridium's existing network architecture. Once completed for each new satellite, a precisely orchestrated process of replacing the original Iridium® satellite with a new Iridium NEXT satellite, known as a 'slot swap (https://www.globenewswire.com/Tracker?data=AV2LSWFmpx5d2hwvRGRHFopLLKIjPhAhxfnZUoSHqQNv4KYZQOJz6DdeHMFm6sxO2CgXU1PjxcMHdAc8A0ZlYI0yPz5mPgEG3Tz6WPDfqIw=)' is completed. To date, the team at Iridium's Satellite Network Operations Center (SNOC) has successfully completed three individual slot swaps, and two dual slot swaps. Two of the new satellites are currently drifting to their assigned orbital plane.

"To say that I am proud of the Iridium satellite network operations team is an understatement," said Scott Smith, chief operating officer at Iridium. "Conducting multiple slot swaps to replace a network of this magnitude is an incredible task, and only Iridium has the team and technical capacity to manage this project. We have been preparing for this process for years, and since first launch the team has worked non-stop to manage each maneuver to successfully integrate the new satellites into the active network. We are thrilled to say that these new satellites are exceeding expectations and are already delivering faster speeds to our customers."

First ten satellites in the Iridium NEXT constellation, built by Thales Alenia Space, now validated in orbit

| 14.06.2017 |

Second batch of satellites ready for a launch scheduled on June 25

Cannes, June 14, 2017 - Following the launch of the first ten Iridium NEXT satellites in January 2017, their commissioning has proceeded very smoothly, as they passed all in-orbit tests with flying colors.

These satellites are now interconnected, and are operating in full compatibility with the initial Block One constellation.

...

"The challenge for Thales Alenia Space was not just to deliver the satellites, but above all to commission the entire turnkey system and make sure that the two generations of satellites were fully compatible," said Bertrand Maureau, Executive Vice President, Telecommunication at Thales Alenia Space. "Our success in this operation clearly confirms our skills and expertise as a leading prime contractor for complex telecommunications systems."
