Цитата: undefinedAriane 5 | July 20, 2020BSAT-4b begins its pre-flight checkout for Arianespace's upcoming Ariane 5 launchThe BSAT-4b broadcasting satellite, which will be orbited by Arianespace as part of a turnkey contract between the Japanese operator B-SAT and the satellite manufacturer, Maxar, is being readied for a July 28 liftoff from the Spaceport in French Guiana on Ariane 5.Moving through a transfer corridor within the Spaceport's S5 payload processing facility, the BSAT-4b broadcasting satellite is moved from the building's S5C large preparation hall to the S5A fueling and integration hall.This 3,530-kg. relay platform is undergoing its preparations in the Spaceport's S5 payload processing facility, and its upcoming liftoff will mark the latest Ariane mission for B-SAT - Japan's leading broadcasting satellite operator - as well as the continuation of Arianespace's long-established launch services relationship with the Japanese satellite broadcasting sector.B-SAT ordered the BSAT-4b satellite from Maxar in 2018 to ensure 4K/8K ultra-high definition direct-to-home video distribution across the Japanese region. It will serve as a back-up geostationary satellite for BSAT-4a, which also was built by Maxar and launched by Arianespace in September 2017.Equipped with 24 Ku-band transponders, BSAT-4b was designed for a service lifetime of 15 years or longer and is based on Maxar's popular 1300-class spacecraft bus for commercial communications satellites.On this month's Ariane 5 mission to geostationary transfer orbit, designated Flight VA253 in Arianespace's launcher family numbering system, BSAT-4b will be integrated in the launch vehicle's lower payload position, joining the other two passengers: the Galaxy 30 relay satellite (G-30); and the Mission Extension Vehicle-2 (MEV-2) - both of which are supplied by Northrop Grumman, and will serve the operational needs of Intelsat.A larger version of the image above is available for downloading in the Gallery..

Цитата: undefinedAriane 5 | July 21, 2020Arianespace to launch three satellites towards Geostationary Orbit on July 28Final step in Ariane 5 latest performance improvement program decided in 2016, Flight VA253 brings the total increase in payload capacity to 300 kg since then.The two of the three companies whose satellites are being launched are both long-standing customers - Intelsat for 37 years and B-SAT for 23 years - clearly proving the excellence of Arianespace's service offering and long-term customer relations.The third, Northrop Grumman's wholly-owned subsidiary, SpaceLogistics LLC, is a first-time customer to Arianespace.Since the reopening of the Guiana Space Center in French Guiana, teams from Arianespace and ArianeGroup have focused on preparing this very innovative mission under the best possible conditions.Arianespace's next Ariane 5 launch from the Guiana Space Center (CSG) in Kourou, French Guiana, is scheduled for Tuesday, July 28, in a launch window from 21:29 UTC to 22:15 UTC.Satellites to be placed in orbit will serve Japanese B-SAT and operators Intelsat and Northrop Grumman's SpaceLogistics LLC. BSAT-4b was built by the American company Maxar Technologies and will be used to broadcast Ultra-High-Definition (UHD, 4K and 8K) direct-to-home television broadcasting across Japan, in conjunction with its twin, BSAT-4a, also built by Maxar and launched by Arianespace in 2017.The other two satellites on this mission were built by the American company Northrop Grumman: the Galaxy 30 UHD video distribution/broadcast and broadband satellite, built for the global network operator, Intelsat, will cover North America, and MEV-2 (Mission Extension Vehicle), a highly innovative satellite servicing vehicle designed to dock to satellites in orbit to provide life extension services. The first customer for MEV-2 will be the Intelsat 10-02 satellite, in geostationary orbit since 2004. MEV-2 will provide five years of service to this satellite.This mission will use the Ariane 5 heavy-lift launcher, developed and manufactured by ArianeGroup, 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. Their customers will continue to benefit from this enhanced performance on Ariane 5 for the rest of its missions.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 the French space agency CNES and the European Space Agency (ESA). ArianeGroup is in charge of all design and production, from initial design studies, upgrades and manufacturing, to the supply of data and software for each mission. Its specific responsibilities include the production of equipment, structures and propulsion systems, integration of the different stages, and integration of the complete launcher in French Guiana.For further information, download the Flight VA253 Launch Kit by clicking here: http://www.arianespace.com/press-kits/

Цитата: undefinedAriane 5 | July 22, 2020Ariane 5 is fully assembled for Arianespace's July 28 launch with Galaxy 30, MEV-2 and BSAT-4bPayload integration for Arianespace Flight VA253 is highlighted with these photos, taken in the upper level of the Spaceport's Ariane 5 Final Assembly Building. At left, BSAT-4b is placed atop Ariane 5's core cryogenic stage. The upper composite - composed of Galaxy 30, MEV-2 and the payload fairing - was then positioned over and installed atop BSAT-4b (center and right).The heavy-lift Ariane 5 for Arianespace's fifth mission of 2020 is now complete following integration of its three passengers at the Spaceport in French Guiana.During activity in Ariane 5's Final Assembly Building, the upper payload component - containing Galaxy 30 (G-30) and the Mission Extension Vehicle-2 (MEV-2) in a stacked configuration - was lowered into position over BSAT-4b, which is installed atop the launcher's central core.This step clears the way for final checkout, which will enable the launch readiness review to be conducted on July 24, followed by Ariane 5's rollout to the Spaceport's ELA-3 launch zone the following Monday. Liftoff is set for the evening of Tuesday, July 28 to deploy the triple payload into geostationary transfer orbit.The upcoming mission is designated Flight VA253 in Arianespace's numbering system. Total payload lift performance is an estimated 10,468 kg.G-30: a milestone spacecraftG-30 is the first satellite in Intelsat's Galaxy fleet replacement program. Its C-band relay capacity will be integral to the U.S. C-band spectrum transition plan that Intelsat is collaborating on with the U.S. Federal Communications Commission.Additionally, G-30 is to provide Ku- and Ka-band relay capability in support of broadband applications, and it carries the Wide Area Augmentation System (WAAS) hosted payload for the U.S. Federal Aviation Administration - offering extremely accurate navigation for civil aviation.Based on Northrop Grumman's flight-proven GEOStar-2 platform, G-30 is the 11th Northrop Grumman-built satellite purchased by Intelsat.MEV-2: new-generation satellite servicingThe MEV-2 passenger for Flight VA253 was supplied by SpaceLogistics LLC, a wholly owned Northrop Grumman subsidiary, and is designed to dock with geostationary satellites whose fuel has nearly depleted, thereby extending their useful lifetimes.After its deployment by Ariane 5, 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. BSAT-4b: reinforcing reliabilityJapanese operator B-SAT ordered the BSAT-4b satellite from Maxar in 2018 to ensure 4K/8K ultra-high definition direct-to-home video distribution across the Japanese region. It will serve as a back-up geostationary satellite for BSAT-4a, which also was built by Maxar and launched by Arianespace in September 2017.Equipped with 24 Ku-band transponders, BSAT-4b was designed for a service lifetime of 15 years or longer and is based on Maxar's popular 1300-class spacecraft bus for commercial communications satellites.Larger versions of the photos above are available for downloading in the Gallery.Launch window for Flight VA253:French GuianaWashington, D.C.Universal TimeParisTokyoBetween 6:29 p.m. and 7:15 p.m. on July 28Between 5:29 p.m. and 6:15 p.m. on July 28Between 21:29 and 22:15 on July 28Between 11:29 p.m. and 12:15 a.m. on July 28-29Between 6:29 a.m. and 7:15 a.m. on July 29
