ЦитироватьAriane 5, Vega | May 13, 2020
Preparations are underway for Arianespace's upcoming Vega and Ariane 5 missions



A pair of important arrivals this week – one by air, the other by sea – marked an acceleration of preparations at Europe's Spaceport for Arianespace's next two missions, to be performed from French Guiana with its lightweight Vega and heavy-lift Ariane 5 launch vehicles.

These parallel arrivals involved personnel who will conduct the first Vega "rideshare" mission, scheduled for mid-June to orbit 53 small satellite payloads; and Ariane 5 launch vehicle components for a three-passenger flight planned for liftoff this summer.

...



... main launcher components for the Ariane 5 flight were being unloaded from the MN Toucan, one of two roll-on/roll-off sea-going ships operated for Arianespace, which docked at Paricabo Port near Kourou. After unloading, the components were to be taken by road to the Ariane 5's ELA-3 launch complex – also situated on the Spaceport's Kourou side.

Launch activities in French Guiana had been suspended mid-March because of the COVID-19 pandemic, and were gradually resumed – carried out in strict compliance with health rules published by the Prefect of French Guiana, as well as the French CNES space agency and the Guiana Space Center.

...

Readying Ariane 5's three-satellite payload

For Arianespace's initial Ariane 5 mission following the resumption of operational activity at the Spaceport, its heavy-lift launcher will carry three payloads to geostationary transfer orbit: the Galaxy 30 and BSAT-4b telecommunications satellites, along with a Mission Extension Vehicle (MEV).

Riding in Ariane 5's upper payload position will be Galaxy 30, produced by Northrop Grumman Innovation Systems (NGIS). This is the first spacecraft built under Intelsat's North American satellite fleet replacement program and highlights the operator's continued focus on C-band communication technologies.

To be deployed as a Galaxy 30 "piggyback" payload is Northrop Grumman's second Mission Extension Vehicle (MEV-2) – a servicing spacecraft that docks with an existing satellite in orbit to provide life-prolonging propulsion and attitude control. After deployment by Ariane 5, MEV-2 will service the Intelsat 10-02 satellite, which was launched in 2004.

Flight VA253's other passenger on Ariane 5 – BSAT-4b – was built by Maxar Technologies for Japan's Broadcasting Satellite System Corporation (B-SAT) as a back-up to BSAT-4a, launched by Arianespace in 2017. BSAT-4b uses Maxar Technologies' 1300 Class platform and carries Ku-band transponders.

A double arrival of Galaxy 30 and MEV-2 for Arianespace's next Ariane 5 mission


During operations at Félix Eboué Airport, Galaxy 30 and Mission Extension Vehicle-2 (MEV-2) are unloaded from the cargo jetliner that transported them to French Guiana for Arianespace's Flight VA253 launch with Ariane 5.

The two payloads that will ride together on Arianespace's upcoming Ariane 5 heavy-lift mission have arrived at the Spaceport in French Guiana to begin their pre-launch processing.

Delivered aboard an Antonov An-125 cargo jetliner last weekend were the Galaxy 30 relay satellite for Intelsat, along with the Mission Extension Vehicle-2 (MEV-2) – a pioneering satellite servicing spacecraft designed to dock with orbiting geostationary satellites whose fuel has nearly depleted.

They were unloaded from the aircraft at Félix Eboué Airport near the capital city of Cayenne for transfer by road to the Spaceport.

Two Northrop Grumman payloads for Flight VA253

Galaxy 30 and MEV-2 will be lofted on the next Ariane 5 mission – designated Flight VA253 in Arianespace's launcher family numbering system – along with the BSAT-4b satellite for Maxar. Liftoff of Flight VA253 is scheduled for the end of July.

The Galaxy 30 spacecraft was built by Northrop Grumman, while MEV-2 was supplied by Space Logistics LLC, a wholly owned Northrop Grumman subsidiary. They will be stacked together to ride in the upper payload position on Ariane 5 for its mission to geostationary transfer orbit.

The Mission Extension Vehicle-2 will be deployed by Ariane 5 for its rendezvous and docking with the Intelsat 1002 satellite, which is scheduled for early 2021. Intelsat 1002 was launched in 2004 by Arianespace, and the MEV-2 will use its own thrusters and fuel supply to control the satellite's orbit, thereby extending its useful lifetime.

Multi-band relay duties for Galaxy 30

Galaxy 30 is based on Northrop Grumman's flight-proven GEOStar-2 platform. As the 11th Northrop Grumman satellite purchased by Intelsat, it is the first in Intelsat's Galaxy fleet replacement program, dedicated to video distribution and broadcast services. With a C-band payload, this spacecraft will be integral to the U.S. C-band spectrum transition plan, on which Intelsat is collaborating with the U.S. Federal Communications Commission.

Additionally, Galaxy 30 has Ku- and Ka-band payloads to support broadband applications, as well as the Wide Area Augmentation System (WAAS) hosted payload for the Federal Aviation Administration. WAAS is an extremely accurate navigation system for civil aviation.

BSAT-4b is delivered to French Guiana for Arianespace's upcoming Ariane 5 mission


Protected in a climate-controlled shipping container, the BSAT-4b satellite is unloaded from an An-124 cargo jetliner at Félix Eboué Airport after arriving in French Guiana.

Payload preparations for Arianespace's next mission have moved into full swing with arrival of the third satellite to be lofted on a heavy-lift Ariane 5 flight from the Spaceport in French Guiana on July 28.

Delivered yesterday by a chartered An-124 cargo jetliner is the BSAT-4b broadcasting satellite, which will be orbited by Arianespace as part of a turnkey contract with the Japanese operator B-SAT and the spacecraft manufacturer, Maxar. The jetliner touched down at Félix Eboué Airport near the capital city of Cayenne, where BSAT-4b was unloaded for transfer by road to the Spaceport.

BSAT-4b will ride in Ariane 5's lower payload position, joining the launch's other two passengers: the Galaxy 30 relay satellite, and the Mission Extension Vehicle-2 (MEV-2) – both of which are supplied by Northrop Grumman, and will serve the operational needs of Intelsat.

The July 28 liftoff is designated Flight VA253 in Arianespace's launcher family numbering system, marking the 253rd mission of an Ariane launch vehicle. It will be Arianespace's fifth mission of 2020 and the third this year to geostationary transfer orbit.

Цитата: undefinedThree U.S.-built satellites in French Guiana for Ariane 5 launch
July 7, 2020 | Stephen Clark

The next flight of Europe's heavy-lift Ariane 5 rocket, set for July 28 from French Guiana, will carry a record payload of three multi-ton satellites toward geostationary orbit, including a pair of U.S.-built commercial communications payloads and Northrop Grumman's second robotic satellite servicing spacecraft.

The Ariane 5 is one of the most powerful rockets in the world, typically carrying two large satellites at a time on missions toward geostationary orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator. The Ariane 5 launches with a carbon fiber structure inside its payload fairing, giving the rocket upper and lower berths inside the nose shroud.

But the Ariane 5's next mission will loft three spacecraft, each with a launch weight of several tons. Two of the satellites will fit together inside the larger upper section of the Ariane 5 payload fairing, while the third spacecraft will ride below in the lower berth.

The end user for two of the satellites is Intelsat, which operates one of the largest fleets of commercial geostationary communications satellites. The owner of the other payload is B-SAT, a Japanese communications satellite operator.

Intelsat's Galaxy 30 video broadcast satellite and Northrop Grumman's second Mission Extension Vehicle arrived at Félix Eboué Airport airport near Cayenne, French Guiana, on June 27 aboard an Antonov An-124 cargo plane. Galaxy 30 and the MEV-2 spacecraft flew to French Guiana from Washington Dulles International Airport, near the Northrop Grumman factory where the satellites were built.

The BSAT-4b television broadcast satellite arrived in French Guiana on July 1 aboard another Antonov An-124 cargo transport, after flying from an airport near Maxar's satellite manufacturing facility in Palo Alto, California, with a stopover in Orlando, Florida.

The three satellites were trucked from the airport near Cayenne to the Guiana Space Center, located in Kourou, French Guiana, for unpacking, testing and fueling.

The 7,760-pound (3,520-kilogram) BSAT-4b satellite will then be mounted on top of the Ariane 5 rocket's upper stage inside the launcher's final assembly building at the European-run spaceport in South America. Galaxy 30 and MEV-2 will be connected together and encapsulated inside the Ariane 5's payload shroud, then the upper composite will be lowered over BSAT-4b before the Ariane 5 rolls out to the launch pad on the day before liftoff.

The Ariane 5 is scheduled for launch July 28 during a 46-minute window opening at 5:29 p.m. EDT (2129 GMT; 6:29 p.m. French Guiana time). The mission will mark the 109th flight of an Ariane 5 rocket since 1996, and the third Ariane 5 flight this year.

It will be the first launch from French Guiana since February. Arianespace, which oversees Ariane 5, Soyuz and Vega launches from the Guiana Space Center, suspended launch operations at the spaceport in March due to the coronavirus pandemic.
Спойлер
Teams resumed regular work at the launch site in May, and Arianespace aimed to launch a light-class Vega rocket last month with a cluster of 53 small satellites. But persistent high-altitude winds kept the mission grounded, and Arianespace decided to recharge batteries on the rocket and on-board its satellite payloads.

The recharging activity on the satellites was expected to take several weeks to complete. Teams planned to remove the Vega rocket's payload composite containing the satellites and transport it back to a clean room facility at the space center, where technicians could open the payload fairing and access the 53 spacecraft.
[свернуть]
Arianespace said last week the Vega launch would be delayed to Aug. 17, and the Ariane 5 launch would proceed July 28.

The Ariane 5 will fly to the east from the Guiana Space Center, and officials do not expect it to be as susceptible to high-altitude wind limits as the Vega launch on a northerly trajectory. The launcher will release the Galaxy 30, MEV-2 and BSAT-4b satellites into an elliptical transfer orbit, and the spacecraft will use their own engines to circularize their orbits more than 22,000 miles over the equator.

MEV-2 is Northrop Grumman's second autonomous satellite servicing spacecraft, following launch of the MEV-1 mission in October 2019 aboard a Russian Proton rocket.

The MEV-1 mission docked with the Intelsat 901 in February, locking onto the satellite after accomplishing the first docking between two commercial satellites, and the first-ever linkup between two objects in geostationary orbit. Intelsat 901 was launched in 2001 and was running low on fuel. The Mission Extension Vehicle is designed to take over attitude control of a client satellite and extend its useful life.

Intelsat purchased life-extension services for two of its satellites from Space Logistics, a subsidiary of Northrop Grumman that manages the commercial robotic servicing program. Intelsat 901 resumed commercial communications service in April.

The MEV-2 mission will perform a similar docking and mission extension service beginning in early 2021 for the Intelsat 10002 communications satellite, which launched in 2004.

An Intelsat communications satellite will accompany MEV-2 into orbit. Named Galaxy 30, the Northrop Grumman-built satellite will provide commercial video and television broadcast services across the United States.

Galaxy 30 will also provide broadband connectivity, and it hosts a Wide Area Augmentation System payload for the Federal Aviation Administration to support navigation services for civil aviation in the United States, including precise altitude and position data for airplanes departing and arriving at busy airports.

The BSAT-4b satellite will be positioned over the Asia-Pacific region, and it will broadcast direct-to-home 8K and 4K ultra-high-definition television services for the Japanese operator B-SAT. The new satellite will be a backup for BSAT-4a, which launched in 2017.

"Double vision" as Galaxy 30 and MEV-2 are readied for Ariane 5's next mission


The Northrop Grumman-built Mission Extension Vehicle-2 (at left) and Galaxy 30 satellite (in the background, at right) are together in the S5 payload processing facility clean room at the Spaceport in French Guiana.

The two Northrop Grumman-built passengers for Arianespace's upcoming Ariane 5 flight are undergoing pre-launch checkout at the Spaceport in preparation for this mission's July 28 liftoff.

Being processed in the Spaceport's S5 payload processing facility are Galaxy 30 (G-30) and the Mission Extension Vehicle-2 (MEV-2) – both of which are slated to serve Intelsat, which operates the world's largest integrated satellite and terrestrial network.

Galaxy 30 and MEV-2 to be stacked on Ariane 5

They will be integrated in a stacked configuration on Ariane 5, riding in the launch vehicle's upper payload position for release first during the flight to geostationary transfer orbit. This mission is designated Flight VA253 in Arianespace's launcher family numbering system, signifying the 253rd launch since the European Ariane family began operation in 1979.

G-30 is the first 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 will extend the Intelsat 1002 satellite's lifetime

The MEV-2 passenger for Flight VA253 was supplied by Space Logistics 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 1002 (IS-1002) satellite, originally launched in 2004. The Mission Extension Vehicle is to utilize its own thrusters and fuel supply to control the IS-1002 satellite's orbit.

Joining MEV-2 and G-30 on Ariane 5 for Flight VA253 will be the 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.
