ЦитатаРакета Ariane 5 с тремя спутниками на борту стартовала с космодрома Куру
ПАРИЖ, 16 августа. /ТАСС/. Европейская ракета-носитель тяжелого класса Ariane 5 с двумя спутниками связи и космическим аппаратом для продления миссий стартовала 15 августа с космодрома Куру во Французской Гвиане. Прямую трансляцию запуска ведет на своем сайте компания-оператор Arianespace.
Ракете предстоит вывести на орбиту спутник BSAT-4b, запускаемый для японского оператора связи B-SAT, и спутник Galaxy 30 для международного оператора Intelsat. Они будут использоваться для прямого высококачественного радио- и телевещания.
В космос также отправился аппарат MEV-2. Он принадлежит американской корпорации Northrop Grumman и предназначен для продления сроков эксплуатации спутников на геостационарной орбите. Он проведет операции, которые позволят продлить срок действия спутника Intelsat 10-02.
Изначально старт должен был состояться 28 июля, однако его перенесли на 31 июля в связи с необходимостью провести дополнительные технические проверки. 31 июля Ariane 5 вновь была снята со стартового стола и возвращена в сборочный цех из-за отказа датчика в баке с жидким водородом основной ступени ракеты. После этого запуск наметили на 14 августа, однако в связи с неблагоприятными погодными условиями его снова пришлось перенести.

ЦитатаAriane 5 | August 15, 2020
Arianespace's Ariane 5 orbits Galaxy 30, MEV-2 and BSAT-4b


The Ariane 5 for Arianespace's Flight VA253 was equipped with a new vehicle equipment bay that enabled the launcher's payload capacity to be increased.

Ariane 5 flexed its heavy-lift muscles on Arianespace's latest launch from the Spaceport in French Guiana, successfully placing the triple payload of Galaxy 30 (G-30), the Mission Extension Vehicle-2 (MEV-2) and BSAT-4b into geostationary transfer orbit.

Designated Flight VA253 in Arianespace's numbering system, today's mission was performed from the Spaceport's ELA-3 launch zone - with Ariane 5 deploying its three passengers during a sequence lasting 47 minutes from liftoff to final separation. It marked the 253rd launch of an Ariane-series vehicle to date, and the 109th using an Ariane 5.

Today's mission utilized an Ariane 5 ECA version with increased payload capacity through the introduction of a new vehicle equipment bay for the launch vehicle. Since kicking off a continuous improvement program for Ariane 5 in 2016, prime contractor ArianeGroup has increased the launcher's payload capacity by 300 kg. for the benefit of Arianespace. This raises the total mass of payload passengers that can be carried by Ariane 5 to 10,200 kg.; for today's mission, the combined mass of G30, MEV-2 and BSAT-4b was 9,703 kg.
"Flight VA253 marked another mission of innovation for us," said Stéphane Israël, the Arianespace Chief Executive Officer. "This was the first time that we delivered three satellites to geostationary transfer orbit on a single launch, and it utilized the most capable Ariane 5 ever - with the increased payload capacity of 10.2 metric tons that is now available for satellite payloads."

Continued success with Intelsat and Northrop Grumman

Deployed first in the flight sequence 27 minutes after liftoff, G-30 is the 62nd satellite Arianespace has launched for operator Intelsat, continuing a business relationship that extends back to 1983. It was produced by Northrop Grumman based on its GEOStar-2 platform, and will provide UHD video distribution/broadcast and broadband services that cover North America.

G-30 was carried as Ariane 5's upper payload component, stacked with the MEV-2, built by Northrop Grumman's wholly-owned company SpaceLogistics LLC. MEV-2 is designed to dock with geostationary satellites whose fuel has nearly depleted, thereby extending their useful lifetimes.

MEV-2 will rendezvous and dock in early 2021 with the Intelsat 10-02 (IS 10-02) satellite, originally launched in 2004. The Mission Extension Vehicle is to utilize its own thrusters and fuel supply to control the IS 10-02 satellite's orbit.
Including G-30 and MEV-2, Arianespace has now orbited a total of 30 spacecraft produced by Northrop Grumman or its companies.

Another launch for Japan's B-SAT with a Maxar-built satellite

The lower passenger in Ariane 5's multi-payload configuration was BSAT-4b, which was orbited for the Japanese operator B-SAT. Produced by Maxar Technologies, it uses this manufacturer's popular 1300-class spacecraft bus for commercial communications satellites.
BSAT-4b is designed for Ultra-High-Definition (UHD, 4K and 8K) direct-to-home television broadcasting across Japan in conjunction with its twin, BSAT-4a - which was launched by an Ariane 5 in 2017. All of BSAT's 10 satellites have been orbited on Arianespace missions.

Ariane 5's launch by the numbers

Flight VA253 was Arianespace's fifth launch so far in 2020, and it follows two other heavy-lift Ariane 5 missions this year: the first orbited the EUTELSAT KONNECT and GSAT-30 satellites in January; while the second, performed in February, lofted JCSAT-17 and GEO-KOMPSAT-2B. Two medium-lift Soyuz missions also were conducted in February and March, with each successfully delivering 34 OneWeb constellation satellites to low Earth orbit.

The next mission in Arianespace's 2020 manifest is the proof of concept flight for Europe's Small Spacecraft Mission Service (SSMS) - which will deploy 46 small CubeSats and seven microsatellites from the light-lift Vega launcher, using a new-design rideshare dispenser system. This flight is planned for September 1.

Triple mission success for Ariane 5: the Galaxy 30, MEV-2 and BSAT-4b satellites reach geostationary transfer orbit



Arianespace's fifth successful mission of 2020 orbited two telecommunications satellites and one satellite servicing vehicle for operators Intelsat, B-SAT and Northrop Grumman.

With this launch for two of its most loyal customers, as well as a new operator, Arianespace demonstrates the reliability and competitiveness of its launch service solutions, as well as the excellence of its long-established customer relationships.

On Saturday, August 15 at 22:04 UTC, Ariane 5 Flight VA253 was successfully performed from the Guiana Space Center, orbiting two satellites produced by Northrop Grumman: Galaxy 30 for Intelsat, and MEV-2 for SpaceLogistics LLC, a 100% subsidiary of Northrop Grumman; along with BSAT-4b, built by Maxar Technologies for the Japanese operator B-SAT.

"Arianespace is delighted to have served two loyal customers - Intelsat and B-SAT - as well as Northrop Grumman's subsidiary, SpaceLogistics LLC," declared Stéphane Israël, the Chief Executive Officer of Arianespace. "As part of this mission, three satellites were deployed by the most powerful Ariane 5 ever launched, thus demonstrating the competitiveness of our launch solutions and our capability for continuous innovation."

The Galaxy 30 UHD video distribution/broadcast and broadband satellite, built for global network operator Intelsat, will cover North America.

BSAT-4b will be used for Ultra-High-Definition (UHD, 4K and 8K) direct-to-home television broadcasting across Japan, in conjunction with its twin, BSAT-4a, launched by Arianespace in 2017.

The Arianespace relationship with satellite operators Intelsat and B-SAT has continued for several decades, and has grown stronger over time. Since 1983 - the date of the first mission for Intelsat - Arianespace has launched 61 satellites on behalf of this global operator. For B-SAT, the Japanese operator has entrusted Arianespace with the launch of its entire fleet - a total of 10 satellites.

Flight VA253's third passenger, the Mission Extension Vehicle-2 (MEV-2), is a satellite servicing vehicle designed to dock with satellites in orbit. It will provide life extension services. MEV-2's first customer will be the Intelsat 10-02 satellite, which has been in service in geostationary orbit since 2004 and will have its operational life extended by five years.

The triple-payload launch performed with Flight VA253 to orbit two telecommunications satellites and a servicing spacecraft is a first for Ariane 5.

Another important point: Flight VA253 utilized the Ariane 5 heavy-lift launcher, developed and produced by ArianeGroup, which has increased its payload capacity by 85 kg. for this flight with the introduction of a new vehicle equipment bay (VEB) - bringing total capacity for the satellite payloads to 10,200 kg. on missions to geostationary transfer orbit (GTO).

This Ariane 5 launcher is thereby the most powerful ever operated by Arianespace, marking the culmination of the continuous improvement program for Ariane 5's performance and competitiveness that was implemented in 2016 by ArianeGroup for the benefit of Arianespace. It has provided a performance gain 300 kg., which continues to be available for customers on Ariane 5 missions planned until the end of the launcher's operation.

The Ariane 5 launcher is a joint European government-industry program. Arianespace is responsible for marketing and operating Ariane 5 launches from the Guiana Space Center in Kourou, French Guiana, with support from teams of the French space agency (CNES) and the European Space Agency (ESA) - which is responsible for the Ariane programs. All industrial activities relating to Ariane 5 are managed by ArianeGroup. This includes the equipment and structures, the manufacturing of engines, integration of the various stages, followed by integration of the complete launcher in French Guiana before its delivery to Arianespace for liftoff.
