ЦитатаAriane 5 | July 30, 2020
Ariane 5 is in the launch zone for Arianespace's July 31 mission with three passengers


The heavy-lift Ariane 5 with its trio of satellite payloads for Flight VA253 is shown in mid-transfer from the Spaceport's Final Assembly Building (left photo), and during final positioning on the ELA-3 launch zone (at right).

The Ariane 5 for Arianespace Flight VA253 has rolled out to the launch zone at Europe's Spaceport in French Guiana, clearing the way for tomorrow's mission with a trio of spacecraft: Galaxy 30 (G-30), Mission Extension Vehicle-2 (MEV-2) and BSAT-4b.

Riding atop a mobile launch table, the heavy-lift launcher completed its transfer from the Spaceport's Final Assembly Building - where payload integration occurred - to the dedicated ELA-3 launch complex.

ArianeGroup is Ariane 5's prime contractor, delivering the fully-assembled launch vehicle for operation by Arianespace.

Geostationary transfer orbit delivery

With today's rollout completed, the final countdown will begin for liftoff on July 31 at the start of a 46-min. launch window that opens at 6:30 p.m. local time in French Guiana (21:30 UTC).

For this 109th launch of an Ariane 5, the lift performance is an estimated 10,468 kg., which factors in the G-30, MEV-2 and BSAT-4b payloads, plus the dispenser system and integration hardware.

The mission will use an Ariane 5 launcher, which has increased its payload capacity by 85 kg. for this flight, thanks to the introduction of a new vehicle equipment bay (VEB) - bringing total payload capacity into geostationary transfer orbit (GTO) to 10,200 kg. Since kicking off a continuous improvement program for Ariane 5 in 2016, ArianeGroup has increased this launcher's payload capacity by 300 kg. for the benefit of Arianespace.

All three passengers are to be deployed into geostationary transfer orbit during a 47-min. flight sequence from liftoff to final separation.

Payloads for operation by Intelsat and B-SAT

To be deployed first during the flight trajectory is Galaxy 30, built by Northrop Grumman for Intelsat. G-30 will provide UHD video distribution/broadcast and broadband services that cover North America.

MEV-2 is to be separated from Ariane 5 in Flight VA253's second deployment step. This highly innovative satellite servicing vehicle, which is built by Northrop Grumman's wholly-owned company, SpaceLogistics LLC, is designed to dock with satellites in orbit, offering life extension services. The initial spacecraft target for MEV-2 is the Intelsat 10-02 satellite, which has been in geostationary orbit since 2004. MEV-2 will provide five years of life extension for this relay platform.

Completing Ariane 5's mission is the deployment of BSAT-4b, designed 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. Built by Maxar Technologies, BSAT-4b will be operated by Japan's Broadcasting Satellite System Corporation (B-SAT).

ЦитатаФранцузская ракета Ariane 5 в пятницу должна вывести на орбиту три космических аппарата
31.07.2020 00:00:00

Париж. 31 июля. ИНТЕРФАКС - Тяжелая ракета-носитель Ariane 5 в пятницу стартует с космодрома Куру во Французской Гвиане с тремя космическими аппаратами, сообщает компания-оператор Arianespace.

Старт планируется осуществить в пятницу во временное окно с 23:30 до 00:16 по парижскому времени (с 00:30 до 01:16 1 августа мск).

Ракета-носитель выведет на орбиту аппарат MEV-2 (Mission Extension Vehicle) американской корпорации Northrop Grumman, предназначенный для продления сроков эксплуатации спутников. Он должен будет состыковаться со спутником связи Intelsat 10-02 на геостационарной орбите, который уже почти исчерпал свои запасы толпива для поддержания ориентации, и "дозаправить" его.

Ракета также выведет на геостационарную орбиту спутник Galaxy 30 компании Intelsat для расширения высокочастотного телевизионного покрытия территории США. На нем, кроме того, размещено оборудование Федеральной авиационной администрации США, предназначенное для совершенствования технического обслуживания полетов гражданских авиации.

Третий спутник, который планируется вывести на орбиту, является японским телекоммуникационным аппаратом BSAT-4b. Созданный компанией Maxar, он будет использоваться для телевизионного вещания в формате сверхвысокой четкости (4K и 8K) в Японии.
