ЦитироватьLauncher integration is underway for Arianespace's first Ariane 5 mission of 2016

December 3, 2015 – Ariane Flight VA228
Build-up of the initial Ariane 5 to be launched in 2016 has begun at the Spaceport in French Guiana, continuing Arianespace's sustained mission pace and readying an unusual single-payload flight for the heavy-lift workhorse.
With liftoff scheduled on January 27, the Ariane 5 is to loft Intelsat 29e – the first of the Intelsat EpicNG high throughput satellites. This relay platform will have one of the most advanced digital payloads commercially available, delivering enterprise-grade, broadband services to fixed and mobile network operators, aero and maritime mobility service providers, and government customers operating throughout the Americas.
As the 56th Intelsat spacecraft to be orbited by Arianespace, Intelsat 29e has the distinction of being a solo telecommunications satellite on a dedicated Ariane 5 flight – instead of the typical two-passenger configuration for the launcher on missions to geostationary transfer orbit.

 

Intelsat 33e also to be launched by Arianespace in 2016

Intelsat expects to launch its second Intelsat EpicNG satellite, Intelsat 33e, in the third quarter of 2016, also using Arianespace launch services. Intelsat 33e will serve Europe, Africa, the Middle East, and Asia.
The January 27 mission with Ariane 5 and Intelsat 29e is designated Flight VA228 in Arianespace's numbering system, notating the 228th launch of an Ariane since this series of European vehicles entered service in 1979.
Flight VA228's Ariane 5 is taking shape inside the Spaceport's Launcher Integration Building where the activity began with the cryogenic core stage's positioning over one of two launch tables for the heavy-lift vehicle. The side-mounted solid propellant boosters were then integrated, followed by installation of the combined upper stage and vehicle equipment bay atop the core stage.
Once the basic build-up is complete, Ariane 5 will be ready for transfer to the Spaceport's Final Assembly Building – where launcher prime contractor Airbus Defence and Space hands over responsibility to Arianespace for Intelsat 29e's integration, final checkout and rollout to the launch pad for liftoff.

A truly "epic" satellite arrives in French Guiana for its Ariane 5 launch

The Intelsat 29e relay platform for Arianespace's first Ariane 5 flight of 2016 is now in French Guiana, enabling payload preparations to begin for a January 27 flight fr om the Spaceport.   
(https://img.novosti-kosmonavtiki.ru/222875.jpg)
Intelsat 29e is moved into position for an initial integration check with its Ariane 5 adapter during activity in the Spaceport's S5 payload preparation facility.
 
Touching down at Cayenne's Félix Eboué Airport, this passenger – the first of the Intelsat EpicNG high throughput satellites – was delivered to French Guiana aboard a chartered Antonov An-124 cargo aircraft, then transferred by road to the Spaceport.
The Boeing-built Intelsat 29e is now set to undergo final checkout and integration with the launcher ahead of next month's liftoff from the South American launch facility – wh ere Arianespace operates its family of the heavy-lift Ariane 5, medium-weight Soyuz and light-lift Vega vehicles.
As the 56th Intelsat spacecraft to be orbited by Arianespace, Intelsat 29e has the distinction of being a solo telecommunications satellite on a dedicated Ariane 5 flight – instead of the typical two-passenger configuration for the launcher on missions to geostationary transfer orbit.
The Ariane 5 flight with Intelsat 29e is designated Flight VA228 in Arianespace's numbering system, representing the 228th launch of an Ariane since this series of European vehicles entered service in 1979.

Riding atop one of two operational launch tables at the Spaceport, the Ariane 5 for Flight VA228 nears completion of its transfer to the Final Assembly Building in the photo at left; while at right, Intelsat 29e is shown during its transfer within the S5 payload preparation building to the S5A fueling and integration hall.
Ariane 5 is on the move as launcher and payload preparations continue in French Guiana for Arianespace's first flight of 2016, which will orbit the initial EpicNG high-throughput satellite for global operator Intelsat.

The heavy-lift vehicle for this upcoming mission – designated Flight VA228 – is now located inside the Spaceport's Final Assembly Building following its transfer by rail from the Launcher Integration Building atop a mobile launch table.
With Ariane 5 now under Arianespace's responsibility, the launcher is in position to receive its Intelsat 29e payload – which will be followed by final verifications and subsequent rollout to the Spaceport's ELA-3 complex for a January 27 liftoff.
Intelsat 29e's own preparations are advancing in parallel activity at the Spaceport's S5 payload processing building. Having already completed its initial check-out process inside this state-of-the-art facility's S5C clean room, the Boeing-built satellite is now being transferred to the S5A fueling and integration hall.
As the first of the Intelsat EpicNG high-throughput satellites, Intelsat 29e will have one of the most advanced digital payloads commercially available – delivering enterprise-grade, broadband services to fixed and mobile network operators, aero and maritime mobility service providers, and government customers operating throughout the Americas.
Intelsat 29e also has the distinction of being a solo telecommunications satellite on a dedicated Ariane 5 flight – which is in contrast to the typical two-passenger configuration for this launcher on missions to geostationary transfer orbit.
The January 27 liftoff will kick off another busy year of mission activity for Arianespace, which is targeting a 2016 performance of up to 11 flights using its full launcher family – consisting of the heavy-lift Ariane 5, medium-lift Soyuz and lightweight Vega – in side-by-side operation at the Spaceport.

The Intelsat 29e satellite is fueled for Arianespace's year-opening Ariane 5 mission
(https://img.novosti-kosmonavtiki.ru/223038.jpg)   
Intelsat 29e receives its propellant load in the Spaceport's S5 payload preparation facility (photo at left), and is installed on the adapter that will serve as the integration interface with its Ariane 5 launcher (at right).
Intelsat's initial EpicNG high-throughput satellite has been fueled at the Spaceport, readying it for the first Arianespace mission of 2016 – which will utilize a heavy-lift Ariane 5 operated from French Guiana on January 27.      
                            
Named Intelsat 29e, this relay platform is based on the Boeing 702MP spacecraft design and will be a solo passenger on the year-opening flight.  This liftoff is the first of up to 11 missions planned with Arianespace's launcher family during the coming 12 months, with as many as eight utilizing the workhorse Ariane 5.
As the series-opening Intelsat EpicNG satellite, Intelsat 29e has one of the most advanced digital payloads commercially available, operating in the C, Ku and Ka frequency bands. It will offer enterprise-grade broadband services to fixed and mobile network operators, aero and maritime mobility service providers, along with government customers.  Coverage area is the Americas and over the North Atlantic (for sea and aviation routes).
With the propellant that was loaded during operations this week in the Spaceport's S5 payload preparation facility, Intelsat 29e will have a liftoff mass of just over 6,550 kg.
Integration of Intelsat 29e on its Ariane 5 is planned for next week, enabling the completed vehicle's rollout to the launch pad on January 26.  Liftoff of the mission – designated Flight VA228 in Arianespace's launcher family numbering system – is targeted for the following night.

ЦитироватьIntelsat 29e Launch: Propulsion Fuel Loading Underway          
(https://img.novosti-kosmonavtiki.ru/230279.jpg)                         
By Brian Sing, Senior Program Manager, Space Systems Acquisition
With two weeks until the launch of Intelsat 29e, excitement is building at the launch site in French Guiana. Since I last wrote, I've been to Paris for the formal acceptance of the launch vehicle by Arianespace, travelled back to California and now I'm in French Guiana, where I'll stay through the launch – set for two weeks from today.
The next step in preparing IS-29e for launch is to fill its fuel tanks. In the last week, the satellite underwent a test to pressurize and verify tank integrity. This was to demonstrate that the tanks have not been compromised in any way since the satellite left the factory in December.
Loading the oxidizer and fuel onto the satellite is the responsibility of the Boeing Propulsion Team, which will load approximately 1550 kg (3400 lbs.) of oxidizer and 2000 kg (4400 lbs.) of fuel into IS-29e. Once fueled, IS-29e will weigh a hefty 6500 kg (14,300 lbs.) – which is close to the weight of three Chevy Suburban Trucks. 
So why so much fuel? After lift-off, the Ariane 5 rocket will drop IS-29e in a Geo Transfer Orbit (GTO). The mission team will then use the satellite's propulsion system to circularize the orbit and take it to the proper longitude at Geosynchronous Orbit (GEO), which is 35,786 km (22,236 miles) above the Equator. Making this trek from GTO to GEO will consume about 2500 kg (5500 lbs.) of fuel. The rest will be used for station-keeping throughout the satellite's life.
The type of fuel in the satellite is called hydrazine. Combined with the oxidizer, it forms a highly effective, powerful fuel for satellite propulsion system.  In order to load the fuel, Boeing Propulsion Specialists must wear protective gear known as "SCAPE suits" (similar to what you would see during HazMat operations). The suits have self-contained pressurized breathing air and are impervious to outside environments.  During fueling operations – which are underway now – only essential personnel in SCAPE suits are near the satellite.
I'll report back soon as we continue to prepare IS-29e for its "EpicNG" journey.

By Brian Sing, Senior Program Manager, Space Systems Acquisition
Intelsat 29e is now fueled for its years-long mission in orbit. With various tests and the fueling procedure now behind us, those of us on the ground in French Guiana can take a moment and reflect on the impact that this one satellite is expected to have – not just for those of us who've worked on it from its inception in 2012 but for all of our Intelsat colleagues who have in some way helped bring us to this point, on the verge of an "epic" era in which the world's first all-digital, commercial satellite platform will deliver next-generation services for customers around the world.
In this photo, team members unfurl the Intelsat banner with pride in front of the mission-ready IS-29e.
As I write this, IS-29e just completed installation on the launch vehicle adapter. The adapter is the mechanism that will release the satellite into GTO after the Ariane 5 completes the burns. Next, we will be transferring the satellite to meet up with the launch vehicle, encapsulating it and mating it to the rocket for its lift-off on 27 January.
I'll write soon on these next activities as we continue readying IS-29e for its launch.

Intelsat's no. 1 EpicNG satellite is installed on Ariane 5 for the year-opening Arianespace launch
(https://img.novosti-kosmonavtiki.ru/223043.jpg)
Intelsat 29e is mated to its Ariane 5 in the Spaceport's Final Assembly Building, marking a milestone in preparations for the year-opening Arianespace mission on January 27.
                            The launch vehicle for Arianespace's first mission of 2016 has received its payload, as the initial Intelsat EpicNG high-throughput satellite has been mated to the Ariane 5 at the Spaceport in French Guiana.
                            
During activity in the Spaceport's Final Assembly Building, this spacecraft – designated Intelsat 29e – was installed atop the launcher yesterday, a step which is to be followed by its encapsulation in the ogive-shaped protective payload fairing. Intelsat 29e will be a solo payload on this January 27 delivery mission to geostationary transfer orbit.
Intelsat is one of the leading customers for launch services with the workhorse Ariane 5, and Intelsat 29e will be the 56th Intelsat satellite launched by Arianespace – continuing a relationship spanning more than 30 years. Intelsat 29e was built by Boeing, with a liftoff mass of just over 6,550 kg.
Next week's mission – Flight VA228 – marks the 228th using an Ariane vehicle since the European series of launch vehicles entered service in 1979, and the 273rd overall to be performed by Arianespace's family of launchers, which is composed of the heavy-lift Ariane 5, medium-lift Soyuz and lightweight Vega.
The January 27 flight kicks off another busy year of activity for Arianespace, with an objective of 11 launches – including as many as eight by Ariane 5, which would be a new all-time record for the heavy-lift launcher.

Ariane 5 is in the launch zone for Arianespace's year-opening mission with Intelsat 29e

Arianespace's first Ariane 5 for liftoff in 2016 has rolled out to the launch zone in French Guiana, clearing the way for tomorrow's mission at the service of this workhorse vehicle's leading commercial customer: Intelsat.   
(https://img.novosti-kosmonavtiki.ru/222880.jpg)
The Ariane 5 nears completion of its transfer fr om the Spaceport's Final Assembly Building – where this workhorse vehicle received its Intelsat 29e payload – to the ELA-3 launch zone.
 
Riding atop a mobile launch table, Ariane 5 today completed its 2,600-meter transfer from the Spaceport's Final Assembly Building – wh ere the Intelsat 29e satellite passenger was integrated – to the dedicated ELA-3 launch complex.
This paves the way for tomorrow's mission, designated Flight VA228 in Arianespace's numbering system – which is scheduled to lift off in a 1-hr., 20-min. launch window that opens January 27 at 8:20 p.m. local time in French Guiana.
For this 228th launch of an Ariane-series vehicle to date, the payload lift performance is approximately 6,700 kg., with Intelsat 29e being deployed to geostationary transfer orbit during a flight sequence lasting just under 30 minutes.
The Boeing-built Intelsat 29e payload is Intelsat's initial next-generation high-throughput EpicNG-series satellite. Operating in the C, Ku and Ka frequency bands, it will offer enterprise-grade broadband services to fixed and mobile network operators, aero and maritime mobility service providers, along with government customers.
After its deployment by Ariane 5, Intelsat 29e – which will become the 56th Intelsat satellite launched by Arianespace to date – is to operate from an orbital position of 310 deg. East.
The January 27 mission opens another busy year of activity for Arianespace, with an objective of performing up to 11 flights – including as many as eight by Ariane 5, which would be a new all-time record for the heavy-lift launcher.

An "Epic" launch: Arianespace's Ariane 5 soars to success for long-time customer Intelsat
(https://img.novosti-kosmonavtiki.ru/223041.jpg)
Arianespace kicked off its fast-paced 2016 operational schedule tonight with the 70th consecutive launch success using Ariane 5, which orbited a pioneering new-generation satellite for this workhorse vehicle's leading commercial customer.
                            
Lifting off exactly on time from the Spaceport's ELA-3 launch zone in French Guiana, Ariane 5 released Intelsat 29e – international operator Intelsat's milestone first high-throughput EpicNG-series spacecraft – into geostationary transfer orbit after a flight sequence that lasted approximately 30 minutes. The mission was designated Flight VA228 in Arianespace's numbering system.

 

30+ years of cooperation

Intelsat 29e, which had a liftoff mass estimated at 6,552 kg., is the 56th Intelsat satellite to be launched by Arianespace to date – extending a long relationship between the two companies that was further underscored by Arianespace Chairman & CEO Stéphane Israël during his comments from the Spaceport.
(https://img.novosti-kosmonavtiki.ru/222883.jpg) (https://img.novosti-kosmonavtiki.ru/222883.jpg)
Flight VA228 was the 84th launch for Arianespace's Ariane 5, which operates from French Guiana.
 
"Our companies started their cooperation more than 32 years ago with the launch of Intelsat 507 in 1983," he said, speaking from the Jupiter control room. "Tonight, we are particularly proud to contribute to Intelsat's goal of delivering global high-throughput satellite services with the launch of the first of its new EpicNG series."
Intelsat 29e has one of the most advanced digital payloads commercially available – operating in the C, Ku and Ka frequency bands. The spacecraft will offer enterprise-grade broadband services to fixed and mobile network operators, aero and maritime mobility service providers, along with government customers; and its coverage area is the Americas and over the North Atlantic (for sea and aviation routes).
Israël added that Arianespace's support for Intelsat is far from over, saying: "Our roadmap is now clear: Arianespace is ready to deliver Intelsat 33 and Intelsat 36 this year, and next year it will be Intelsat 37. "
During his own post-launch comments, Intelsat CEO Stephen Spengler paid tribute to Arianespace for another successful launch with one of the company's spacecraft. He added: "It is known for delivering, and tonight, Arianespace delivered."

 

A warm welcome back to Europe's Spaceport

Payload prime contractor Boeing also was acknowledged following Intelsat 29e's successful launch, as it marked the first time in more than eight years that one of the company-built satellites was orbited on an Arianespace mission. With tonight's flight, the company has launched 51 Boeing-built spacecraft in total.
Speaking to the Boeing team members in attendance, Israël added: "We are on track for another series of successful launches with no less than four of your future satellites in our order book."

During the live broadcast of Flight VA228, Intelsat team members celebrate Arianespace's successful launch of Intelsat 29e in the Jupiter control room.
 
These four spacecraft consist of the two additional Intelsat satellites for launch in 2016 and 2017; along with SES-15 – which will be orbited for operator SES, and one for an undisclosed customer.
Boeing Satellite Systems President Mark Spiwak was in attendance at the Spaceport and offered his own special take on Arianespace's role in the Flight VA228 success. "It was cloudy all day today, and Stéphane – I don't know how you did it – but as the rocket was ready to go, the clouds parted and it was a beautiful evening." He added jokingly: "I commend Arianespace for having a higher ability to control the weather."

 

A launch, and year, to remember

Tonight's mission was unique for more than its pioneering EpicNG payload. First, Intelsat 29e has the distinction of being a single telecommunications satellite on a dedicated Ariane 5 flight – which is in contrast to the typical two-passenger configuration for this launcher on missions to geostationary transfer orbit.
Flight VA228 also was the first Arianespace mission since 2002 to be performed in the month of January – giving the company an excellent start as it targets a record operational year for Ariane 5, with as many as eight launches to be performed in 2016 using the heavy-lift vehicle.
"Be it for telecommunications or other applications such as ATV (Automated Transfer Vehicle resupply spacecraft) toward the International Space Station, nobody should dispute that Ariane 5 has already made history in the launch industry," said Arianespace's Israël as he looked to the future successor. "We do not intend to rest on our laurels. 2016 will be the year of the full confirmation of Ariane 6, which will be our success story for the next decade."
Altogether, Arianespace has the objective of performing up to 11 missions in 2016 with its full launcher family of today – consisting of the heavy-lift Ariane 5, medium-lift Soyuz and lightweight Vega.

МОСКВА, 10 апр - РИА Новости. Телекоммуникационный космический аппарат Intelsat 29e одного из крупнейших в мире международных спутниковых операторов Intelsat отказал, проработав всего три года из 15 гарантированных разработчиком - американской компанией Boeing.

Спутник Intelsat 29e был выведен на орбиту ракетой-носителем Ariane 5 с космодрома Куру в январе 2016 года. Он создан компанией Boeing и должен был проработать 15 лет.

"Вечером 7 апреля двигательная установка Intelsat 29e получила повреждение, которое привело к утечке топлива на борту спутника и прекращению предоставления услуг потребителям", - говорится в сообщении на сайте оператора Intelsat.

Отмечается, что 9 апреля при проведении восстановительных работ на спутнике произошла вторая нештатная ситуация, которая привела к потере связи с ним.

Оператор продолжает взаимодействовать с Boeing для восстановления связи с космическим аппаратом. Параллельно Intelsat перенаправляет потребителей отказавшего спутника на другие космические аппараты.

Updated at 4:45 p.m. MT. 

COLORADO SPRINGS — Intelsat's first Epic-series high-throughput satellite, Intelsat-29e, is drifting in orbit after back-to-back anomalies, forcing the company to shift customers to other spacecraft.

Intelsat said April 10 that the propulsion system on the three-year-old satellite "experienced damage" — the cause of which it did not identify — resulting in a fuel leak.

While attempting to restore services fr om the satellite, Intelsat said a second problem surfaced that resulted in a loss of communications with the satellite.

Intelsat said its connection with Intelsat-29e has been intermittent, and that it is working with Boeing, the manufacturer of the satellite, on restoring uninterrupted communications. The fuel leak occurred April 7, Intelsat said.

Commercial space situational awareness company ExoAnalytic Solutions said its network of ground-based telescopes identified debris around Intelsat-29e on April 8.

Doug Hendrix, ExoAnalytic's chief executive, told SpaceNews two prominent pieces of debris were identified April 10, but that the company can't determine it they are frozen fuel or something else.

"What we're confident in saying is they've had an anomaly; they have announced an anomaly. We believe that we have seen debris come off of the satellite," he said at the 35th Space Symposium here.

Intelsat said it "will not make a determination of financial impact until the conclusion of the recovery mission."

In a statement, ExoAnalytic said Intelsat 29e was "in a geostationary orbit at 50 [west] longitude until April 8, when it began tumbling and drifting to the east" along the geostationary arc wh ere most telecom satellites reside.

Intelsat-29e is the second Intelsat Epic satellite to experience a propulsion anomaly. In 2016, Intelsat-33e suffered a thruster issue that insurers estimated could shave 18 months off its design life. Boeing built five of the six Intelsat Epic satellites, and supplied the payload for Intelsat-32e, which used a bus from Airbus Defence and Space.

МОСКВА, 12 апр - РИА Новости. Вышедший из строя спутник связи Intelsat 29e неконтролируемо дрейфует на геостационарной орбите, угрожая функционирующим космическим аппаратам, сообщили американские эксперты.

Ранее один из крупнейших в мире международных спутниковых операторов Intelsat сообщил об отказе своего космического аппарата Intelsat 29e. Спутник был выведен на орбиту ракетой-носителем Ariane 5 с космодрома Куру в январе 2016 года. Он создан компанией Boeing и должен был проработать 15 лет.

ЦитироватьStricken with fuel leak, Intelsat 29e seen drifting in geostationary orbit
April 15, 2019 (https://spaceflightnow.com/2019/04/) | Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)

A Boeing-built Intelsat communications satellite launched three years ago is drifting in geostationary orbit after suffering a fuel leak and releasing debris fragments last week, according to an analysis by space surveillance experts.

Ground-based telescopes operated by ExoAnalytic Solutions, a commercial company that tracks objects in space with a network of optical telescopes, show the Intelsat 29e communications satellite is tumbling, leaking propellant and drifting through the geostationary arc, where numerous communications satellites are stationed more than 22,000 miles (nearly 36,000 kilometers) over the equator.

The telescopic imagery also appears to show several pieces of debris came off the satellite last week, according to Bill Therien, executive vice president of engineering at ExoAnalytic Solutions.

In an April 10 statement, Intelsat said the Intelsat 29e spacecraft "experienced damage" on April 7 that resulted in a propellant leak. The event knocked Intelsat 29e out of service, and Intelsat said it was moving customers to other Intelsat satellites and third-party services to mitigate the outage, which affects maritime, aeronautical and wireless operator customers in the Latin America, Caribbean and North Atlantic regions.

In an interview with Spaceflight Now late Friday, Therien said ExoAnalytic's sensors detected a change in the brightness of Intelsat 29e on April 8, suggesting the spacecraft was tumbling. Tracking data collected by ExoAnalytic also showed the satellite began drifting east fr om its operational position around the same time.

Intelsat said Intelsat 29e experienced a second anomaly April 9 that caused a loss of communication with the satellite. On April 10, ExoAnalytic's sensors detected a piece of debris coming off the satellite, followed by more fragments over the next couple of days, Therien said.

"Communication with the satellite has been intermittent," Intelsat said in a statement. "Intelsat continues to work with the satellite's manufacturer, Boeing, on recovering communication."

Therien said the largest of the debris seen coming off Intelsat 29e is no more than a meter, or about 3.3 feet, in size. A shower of smaller particles observed by ExoAnalytic could be fuel leaking out of the satellite's propellant tanks, or pieces of the spacecraft itself, Therien told Spaceflight Now.

Intelsat 29e was launched Jan. 27, 2016, aboard an Ariane 5 rocket fr om French Guiana for a planned 15-year mission. Based on the Boeing 702MP satellite design, Intelsat 29e was positioned in geostationary orbit at 50 degrees west longitude, wh ere its thrusters kept the satellite parked over the same geographic region, with the spacecraft's orbital velocity matching the rate of Earth's rotation.

Since beginning commercial service three years ago, Intelsat 29e provided C-band video and data distribution services over South America, and beamed Ku-band signals across the Americas, including aeronautical routes over the North Atlantic, wh ere passengers received live television and broadband Internet through the satellite.

Intelsat 29e was the first craft to launch in a new generation of Intelsat satellites known as the "Epic" series, which are capable of routing more data than earlier satellite models.

Engineers continue studying the cause of the anomaly on Intelsat 29e, and officials have not said whether the problem originated within the spacecraft or from a collision with a micrometeoroid or a piece of space junk.

The behavior of Intelsat 29e is reminiscent of failures aboard the AMC 9 and Telkom 1 communications satellites in 2017. Both of those satellites shed debris after suffering sudden anomalies in geostationary orbit.

AMC 9 and Telkom 1 — built by Thales Alenia Space and Lockheed Martin, respectively — were near the end of their service lives when those failures occurred, while Intelsat 29e is still a relatively young spacecraft.

PRESS RELEASE | 18 APRIL 2019

Customers Transitioning to Restoration Capacity

Luxembourg, 18 April 2019 – Intelsat S.A. (NYSE: I) announced today that the anomaly previously disclosed on April 10, 2019 has resulted in the total loss of the Intelsat 29e spacecraft. A failure review board has been convened with the satellite's manufacturer, Boeing, to complete a comprehensive analysis of the cause of the anomaly.

Late on April 7, the Intelsat 29e propulsion system experienced damage that caused a leak of the propellant on board the satellite resulting in a service disruption to customers on the satellite. While working to recover the satellite, a second anomaly occurred, after which all efforts to recover the satellite were unsuccessful.

Since the anomaly, Intelsat has been in active contact with affected customers. Restoration paths on other Intelsat satellites serving the region and third-party satellites have been provided for a majority of the disrupted services. Migration and service restoration are well underway; highlighting the resiliency of the Intelsat fleet and the benefit of the robust Ku-band open architecture ecosystem.
