Using Gunter's Space Page as a source, the total mass of both ViaSat 2 and Eutelsat 172B is 9,900 kilograms; the former is 6,400 kilograms while the latter is 3,500 kilograms.

What I'm implying is that this satellite duo will be the heaviest ever launched on an Ariane 5, if you exclude the adapters and Sylda DPAF.

Ariane 5   May 24, 2017
Arianespace to serve global connectivity for ViaSat Inc. and Eutelsat

For its sixth launch of the year, and the third Ariane 5 mission in 2017 from the Guiana Space Center in French Guiana, Arianespace will orbit two satellites: ViaSat-2 for ViaSat Inc.; and EUTELSAT 172B for Eutelsat.

This mission – the 237th overall by an Ariane launcher – will mark a new all-time Arianespace record for a total payload weight orbited: 10,865 kg., including a net mass at liftoff of 9,969 kg. for the two satellites.

ViaSat-2 and EUTELSAT 172B are the 558th and 559th satellites to be launched by Arianespace.

With this 289th mission by the Arianespace family of launchers (Ariane 5, Soyuz and Vega), Arianespace is serving global connectivity on Earth.

The launch will be from Ariane Launch Complex No. 3 (ELA 3) in Kourou, French Guiana.

The Launch Readiness Review (LRR) will take place on Tuesday, May 30, 2017 in Kourou, to authorize the start of operations for the final countdown.

ViaSat-2 is the first ViaSat satellite to be launched by Arianespace.

ViaSat Inc., a new customer for Arianespace and its Ariane 5 launch vehicle, provides international communities with broadband internet connectivity, accessible on land, at sea and in the air, at competitive rates in relation to other satellite or terrestrial services.

The ViaSat-2 satellite system should bring considerable improvements in terms of speed, lower costs and extended broadband coverage within its footprint, as well as along the main aeronautical and maritime routes linking North America and Europe (Atlantic Ocean).

ViaSat-2 will also provide nearly twice the capacity offered by previous generations of ViaSat satellites, along with seven times as much coverage.

Positioned at 70° West, ViaSat-2 will provide throughput of approximately 300 Gbps in Ka-band over its coverage zone, which includes North and Central America, plus the Caribbean, northern South America, and aeronautical and maritime routes in the Atlantic Ocean between North America and Europe.

ViaSat-2 was built by Boeing in El Segundo, California, using a 702HP platform.

EUTELSAT 172B will be the 32nd satellite launched by Arianespace for Eutelsat. Both companies have worked side-by-side since 1983, when Arianespace launched the Eutelsat-1 F1 satellite. Including this upcoming launch, more than half of Eutelsat’s satellites will have been orbited by Arianespace.

Eutelsat is one of the world’s leading and most experienced operators of communications satellites. The company provides capacity on 39 satellites to clients that include broadcasters and broadcasting associations; pay-TV operators; video, data and Internet service providers; enterprises and government agencies.

EUTELSAT 172B will deliver increased capacity for fast-growing applications that include in-flight and maritime connectivity, cellular backhaul, corporate networks, video distribution and government services. It will be located at 172° East, a key neighborhood providing exceptional Asia-Pacific reach over land and sea, from Alaska to Australia.

EUTELSAT 172B is the first all-electric telecommunications satellite built in Europe. This key enabling technology has been implemented by Airbus in Toulouse, using the new all-electric Eurostar E3000 EOR (Electric Orbit Raising) platform.

For further information, download the Launch Kit by clicking here: http://www.arianespace.com/press-kits/

To watch a live, high-speed online transmission of the launch (including commentary from the launch site in French and Eng-lish), go to arianespace.com on June 1, 2017 starting 15 minutes before liftoff.

You also can follow the launch live on your iPhone or iPad (the Arianespace HD app is free).

Ariane 5   May 30, 2017
Arianespace’s Ariane 5 is “go” for liftoff on June 1 with the ViaSat-2 and EUTELSAT 172B satellite passengers

The sixth Arianespace launch of 2017 is approved for liftoff on June 1 from the Spaceport in French Guiana, with its dual-satellite payload of ViaSat-2 and EUTELSAT 172B.

The authorization for this week’s mission – designated Flight VA237 in Arianespace’s launcher family numbering system – followed today’s Launch Readiness Review, which confirmed the “go” status for Ariane 5, its two spacecraft passengers, the Spaceport infrastructure and the network of tracking stations.

Flight VA237’s Ariane 5 is now ready for rollout from the Final Assembly Building, where ViaSat-2 and EUTELSAT 172B were integrated on the launcher, to the Spaceport’s ELA-3 launch zone.

Liftoff will commence as soon as possible in a one-hour launch window that opens at 8:45 p.m. in French Guiana (between 23:45 and 00:45 Universal Time, during the night of June 1 to June 2).

ViaSat-2 and EUTELSAT 172B will be deployed into geostationary transfer orbit on a mission lasting just under 42 minutes.

Released first will be ViaSat-2, which is expected to bring considerable improvements in terms of speed, lower costs and extended broadband coverage within its footprint, which includes North and Central America, plus the Caribbean, northern South America, and the aeronautical and maritime routes in the Atlantic Ocean between North America and Europe. As a global broadband services and technology company, ViaSat operates from corporate headquarters in Carlsbad, California.

ViaSat-2 was built by Boeing in El Segundo, California, using a 702HP platform, and will be positioned at 70 deg. West.

EUTELSAT 172B’s deployment by Ariane 5 will complete Arianespace’s Flight VA237. Operating at an orbital position of 172 deg. East for Asia-Pacific reach over land and sea from Alaska to Australia, the relay platform will deliver increased capacity for fast-growing applications that include in-flight and maritime connectivity, cellular backhaul, corporate networks, video distribution and government services. This satellite will join the fleet of Paris-based Eutelsat, a leading satellite operator in Europe, the Middle East and Africa.

Using the new all-electric Eurostar E3000 EOR (Electric Orbit Raising) platform assembled by Airbus in Toulouse, France, EUTELSAT 172B is the initial all-electric telecommunications satellite built in Europe – and the first of its type orbited by Ariane 5.

Flight VA237 maintains Arianespace’s busy launch schedule in 2017, during which the company is targeting a total of 12 flights using its heavy-lift Ariane 5, medium-lift Soyuz and lightweight Vega vehicles. The five missions already performed this year have utilized two Ariane 5s, two Soyuz launchers and one Vega.

Arianespace marks its 2017 mid-year launch milestone with a record-setting Ariane 5 mission at the service of ViaSat and Eutelsat

On its sixth successful launch during the first half of 2017, Arianespace set a new heavy-lift record tonight with Ariane 5 in delivering the ViaSat-2 and EUTELSAT 172B telecommunications satellites to geostationary transfer orbit.

This mission underscored the increased payload lift capability provided for the Ariane 5 ECA version during the heavy-lift workhorse’s operational career, setting another record for the total mass carried into geostationary transfer orbit. The delivery involved a total payload of 10,865 kg. – of which 9,969 kg. was the net liftoff mass for the two satellites, with the other mass including integration hardware for Ariane 5’s dual-payload deployment system.

“With this new mission, Arianespace once again demonstrates the availability and versatility of its launch vehicle family for customers,” explained Arianespace CEO Stéphane Israël.  “For the third time this year and the 79th time in a row, Ariane 5 performed flawlessly. Well done! Congratulations to all!”

Providing more lift capability to the workhorse Ariane 5 ECA

Speaking from the Spaceport, Israël noted the Ariane 5 ECA’s payload lift capability has been given an overall performance gain of more than 1.5 metric tons since the beginning of this launcher program, and will be further increased in steps through 2019, boosting it by another 250 kg. – enabling Arianespace to meet evolving customer requirements.

This enhancement involves support of the European Space Agency, the French CNES space agency and Ariane 5 industrial prime contractor Airbus Safran Launchers, he added.

Tonight’s mission – designated Flight VA237 in Arianespace’s launcher family numbering system – keeps the company on track for the 12 flights targeted in 2017. It follows the five previous launches this year – two by Ariane 5, two by Soyuz and one by Vega – and clears the way for Arianespace’s next Ariane 5 mission, scheduled for June 28, along with three more Ariane 5 liftoffs and two Vega launches planned during the second half of 2017.

The first passenger released during Flight VA237 was ViaSat-2, which is to be operated from an orbital position of 70 deg. West by ViaSat Inc. – a global broadband services and technology company headquartered in Carlsbad, California, USA.

ViaSat-2: enhancing connectivity over a wide coverage area

With the goal of improving global connectivity, ViaSat-2 is to bring considerable improvements in terms of speed, lower costs and extended broadband across its coverage zone – which includes North and Central America, plus the Caribbean, northern South America, and aeronautical and maritime routes in the Atlantic Ocean between North America and Europe.

ViaSat-2 was the second satellite to be launched by Arianespace for ViaSat. Based on Boeing’s 702HP platform, it also was the 54th Boeing-built satellite orbited by the launch services company.

ViaSat Chairman and CEO Mark Dankberg, who watched the launch from the Spaceport’s Toucan viewing site, said Flight VA237’s liftoff was “spectacular,” and he thanked Arianespace for a “fabulous job.”

An electric satellite first for Ariane 5 with EUTELSAT 172B

Completing tonight’s Flight VA237 was the deployment of EUTELSAT 172B – the 32nd satellite launched by Arianespace for Paris-based Eutelsat, a leading satellite operator in Europe, the Middle East and Africa.

EUTELSAT 172B will increase Eutelsat’s capacity for fast-growing applications, such as in-flight and at-sea connectivity, mobile network interconnections, video and government services. Built by Airbus, it will be positioned at 172 deg. East – a strategic orbital position for coverage of Asia-Pacific, on land and at sea, from Alaska to Australia.

As the 118th Airbus-produced satellite orbited by Arianespace, this spacecraft uses the Eurostar E3000 EOR (Electric Orbit Raising) platform – becoming the first all-electric telecommunications satellite orbited by an Ariane 5.

Yohann Leroy, Eutelsat’s Chief Technical Officer and Deputy CEO, said that Flight VA237 demonstrated Arianespace’s ability to “efficiently and competitively place very powerful electric propulsion satellites into orbit” with Ariane 5.

An on-target delivery for ViaSat-2 and EUTELSAT 172B

Ariane 5 continued its accurate deployment of Arianespace’s customer satellites, with the following initial estimated orbital parameters at injection:

– Perigee: 249.0 km. for a target of 248.9 km.
– Apogee: 35,860 km. for a target of 35,848 km.
– Inclination: 6.00 deg. for a target of 6.00 deg.

[Space Intel Report] Interview: ViaSat President and COO Richard A. Baldridge
Quote
Q: How long until ViaSat-2 gets to final GEO position?

A: We finished the chemical part of the orbit raising and the current assessment is October arrival on station. Our co-passenger [Eutelsat’s all-electric 172B] wasn’t determined initially, and turned out to have greater mass than most. A lighter co-passenger would have allowed more chemical propellant and a shorter overall orbit raising time. But we’re still happy with the trade-off, given that we’ll have the use of the payload capability for far longer than the difference in the orbit raising time.

OKB Torch. New record of the EUTELSAT engines SPT-140
31.10.2017 15:24

The spacecraft (spacecraft) EUTELSAT 172, which is equipped with the SPT-140 electric motors, produced by the Kaliningrad OKB "Torch" (part of State "the"), beat the last record on the fastest decommissioning ( Geostationary orbit, using the SPT-140 electric motors. Only four months have elapsed since it was launched before the geostationary orbit was reached.

During the recovery phase, the motors apparatus worked successfully and withdrew the satellite to the target orbit. The fuel was used six times less than for satellites with chemical engines.

According to the plan, EUTELSAT 172 should start operating for commercial purposes in November of this year to provide communication, broadband and data collection services over the Asia-Pacific region. A satellite constructed by the Airbus for Eutelsat is designed for a 15-year resource. Further adjustments to the orbit of the spacecraft will also be provided by the electric motors produced in the OKB torch. The spacecraft was launched from Kourou on June 1, 2017, on the Ariane-5 launch vehicle.
