Galaxy 30 will share the upper berth of an Ariane-5ECA rocket with MEV 2, while a third yet unnamed payload flies in the lower berth.

The Media Network for the Future: Introducing Galaxy 30
By Kurt Riegelman, Intelsat’s Senior Vice President of Sales, Marketing and Communications, 11 January 2018
Quote
Last week, Intelsat announced the first in a series of orders that will see this fleet replaced with a third generation of technology that will bring advanced media distribution capabilities to television programmers in North America. This is the beginning of a multi-satellite investment program that will offer our customers a technology path for media distribution throughout the next decade. Galaxy 30, which represents the first of many satellites to be built under our North America fleet replacement plan, demonstrates our commitment to ensuring C-band services continue to be the go-to media distribution technology for years to come.  Here’s why:

1.  Our satellite fleet simultaneously delivered the National College Championship game to millions of homes in America. No other technology allows consumers to simultaneously watch programming that is ‘five nines’ reliable, with the highest quality and without annoying buffering issues. This is why preserving C-band spectrum is vital and we are committed to ensuring our customers can continue to provide quality programming without fear of interference from wireless services. During the past 30 years, we have continually upgraded our fleet capabilities as our customers delivered analog channels, which then transitioned to digital standard definition formats, and ultimately established the first high definition video neighborhoods on Intelsat’s Galaxy platform. With Galaxy 30, we continue this evolution by pairing higher satellite performance with our unmatched penetration of US cable headends. This allows the delivery of UHD content to current cable distribution platforms as well as new distribution platforms such as OTT and multichannel video programming distributors. Intelsat leads the way in deploying increased performance, economics and accessibility.

2.  Galaxy 30 demonstrates our unwavering commitment to preserving the quality and reliability for which our C-band programming distribution is known. When we filed our market-based proposal for joint-use of C-band in conjunction with Intel last October, we stated two key objectives: create a solution that assures the continued use of C-band in video distribution and accelerate the adoption of technologies that will advance new content outlets, such as 5G. Galaxy 30 provides tangible proof of our assertions that we will not compromise on the certainty, reliability and quality of the satellite services we provide; that satellite must remain primary in the C-band frequencies; and that any joint-use of our frequency must be implemented in a way that provides controls to ensure interference-free distribution.

One thing remains certain. Change in the broadcast industry is constant and accelerating exponentially while new types of content and distribution platforms are being created. By partnering with our customers to deploy increased performance “in space” as well as enacting logical frequency allocation policies “on the ground,” we can help our programming clients provide their customers with top-quality service, and secure and grow revenues today and tomorrow.

Intelsat signs contract with Arianespace for two launches, dated January 9, 2018.  See also here.

Arianespace signed an agreement to launch two satellites for longtime customer Intelsat, one of the world’s largest satellite operators. This continues the longstanding relationship between Intelsat and Arianespace that dates back to 1983.

The first launch will carry the Galaxy 30 satellite together with the Orbital ATK Mission Extension Vehicle-2 (MEV- 2) as a stacked pair. Galaxy 30 will be the first replacement satellite for the North American Galaxy Fleet and in addition to its C-band payload, Galaxy 30 will include Ku- and Ka-band payloads to support broadband applications in North America. The launch of Galaxy 30 demonstrates Intelsat’s commitment to its distribution neighborhoods, which has an unmatched penetration of cable headends in the United States. Galaxy 30 is based on Orbital ATK’s GEOStar-2™ satellite platform.

The MEV-2 satellite is owned by Orbital ATK’s Space Logistics LLC subsidiary. Intelsat will be the first customer of the MEV-2. The MEV-2 provides life-extending services by taking over the orbit maintenance and attitude control functions of a client’s spacecraft.

Under the contract, Arianespace will also launch an additional satellite for Intelsat in the second half of 2020.

“Arianespace is honored yet again to be selected by Intelsat for the safe and timely delivery of its satellites. Going back nearly four decades, we’ve always enjoyed a relationship of mutual confidence with Intelsat.  We are proud to be able to perpetuate this epic friendship with two more launches, one of which will feature stacked payloads in the upper position of the Ariane 5, proof of our ability to bring to the table the most innovative solutions for our customers,” declared Stéphane Israël, CEO of Arianespace.

“Arianespace has been one of Intelsat’s most long-standing and trusted partners”, said Ken Lee, Senior Vice President, Space Systems, Intelsat. “Since 2016, Arianespace has successfully completed 5 missions on behalf of Intelsat, including 4 that included our next generation Intelsat EpicNG spacecrafts. We continue to have the utmost confidence in Arianespace and look forward to the successful execution of the innovative Galaxy 30 and Mission Extension Vehicle 2 dual launch mission.”

Arianespace will launch the first pair of satellites, Intelsat’s Galaxy 30 satellite and the MEV-2, in early 2020 from Europe’s Spaceport in South America aboard an Ariane 5 launch vehicle.

BSAT-4b

Maxar Technologies’ SSL Selected as Trusted Partner to Provide Direct Broadcasting Satellite to B-SAT
New satellite will ensure highest quality broadcast capability for the 2020 Olympics

Quote
Palo Alto, Calif. – March 26, 2018 – SSL, a Maxar Technologies company (formerly MacDonald, Dettwiler and Associates Ltd.) (NYSE: MAXR; TSX: MAXR) today announced that it was selected as a trusted partner to provide a broadcasting satellite for Broadcasting Satellite System Corporation (B-SAT). As the leading broadcasting satellite operator in Japan, B-SAT will use the Direct-to-Home (DTH) television satellite to ensure exceptional ultra-high definition video distribution for the 2020 Tokyo Olympics.

“We are honored to provide a second satellite to B-SAT that will help ensure high-quality distribution of the 2020 Olympic Games,” said Dario Zamarian, group president of SSL. “We believe there is no greater endorsement of our capabilities than repeat orders from satisfied satellite operators and we look forward to continuing our good relationship with our partners at B-SAT.”

SSL provided BSAT-4a to B-SAT in November 2017, and BSAT-4b will be a similar high-performance Ku-band broadcasting satellite. BSAT-4b will be co-located with BSAT-4a at 110 degrees East Longitude, and will function as a back-up that will secure highly-reliable services.

“SSL completed BSAT-4a ahead of schedule and it is successfully operating on orbit,” said Takashi Yabashi, president and chief executive officer of B-SAT.  “We are pleased to extend our very good relationship with SSL to continue our partnership on the BSAT-4b spacecraft.”

B-SAT-4b is designed to provide service for 15 years or longer, and is based on the world’s most popular commercial communications satellite platform, the SSL 1300, which has the capability to support a broad range of applications and technology advances.

Arianespace to launch BSAT-4b; marking the 10th satellite launch for B-SAT, dated April 19, 2018
Quote
Arianespace announced today that it will launch BSAT-4b, under the term of a turnkey contract between B-SAT and Maxar’s SSL.

BSAT-4b will be launched by an Ariane 5 in 2020 from the Guiana Space Center, Europe’s Spaceport in Kourou, French Guiana, as part of a turnkey contract between the Japanese satellite operator B-SAT and the California-based satellite manufacturer SSL.

Since the creation of B-SAT, Arianespace has launched all nine of its satellites.

BSAT-4b will be the 10th satellite launched for B-SAT and the 32nd commercial geostationary satellite launch contract awarded to Arianespace in Japan.

Built by SSL, a Maxar Technologies company, using a 1300 platform, BSAT-4b will feature 24 Ku-band transponders. It will weigh about 3,520 kg at launch and is designed to have a nominal service life of at least 15 years. It will be positioned in geostationary orbit at 110 degrees East.

BSAT-4b will serve as a back-up of BSAT-4a, which was launched by Arianespace in September 2017. It will have the same Japan archipelago footprint as BSAT-4a, providing Direct-To-Home (DTH) television to ensure exceptional 4K/8K ultra-high definition (UHD) video distribution for the 2020 Tokyo Olympic Games.

Following the signature of this contract, Stéphane Israël, CEO of Arianespace, said: “Only seven months after the successful launch of BSAT-4a in September 2017, we are honored to have been selected for the launch of BSAT-4b for our long-lasting partner B-SAT. This new Ariane 5 launch contract is a clear demonstration of the excellent relationships between Arianespace, SSL and the Japanese operator B-SAT, for whom we have launched the entire fleet of satellites since 1997. We are proud to serve one more time the Japanese market and to actively participate to the implementation of B-SAT’s ambitious projects, in partnership with SSL.”

Why Intelsat’s going with life extension over refueling, e-article July 11, 2018; print article June 4, 2018
Quote
Earlier this year [2018], Intelsat ordered a second Mission Extension Vehicle from Orbital ATK. Intelsat hasn’t said which one of its more than 50 geostationary satellites will be given an extended lease on life when MEV-2 enters service in mid-2020.
<snip>
Ken Lee, Intelsat’s senior vice president of space systems, said during an interview from his Tysons Corner, Virginia, office late last month:
Q: Have you decided on the use of MEV-2?

A: Yes, we have but I am not going to disclose what it is.
***

This may be a dumb question, but could a third satellite launch with Galaxy 30/MEV-2?
Yes, there will be a third sat in the lower position of the fairing. Galaxy 30/MEV-2 will fly as a joint payload in the upper position.

Although the launch windows do not perfectly align, I posit that Galaxy 30 and MEV-2 could be the upper berth payload, and GEO-KOMPSAT-2B could be the lower berth payload for a hypothetical VA252.
 
Planned launches:
Date - Satellite(s) - Rocket - Launch Site - Time (UTC)

2020
February-March - GEO-KOMPSAT-2B (GK2B, Cheollian 2B) - Ariane 5 ECA - Kourou ELA-3 below the Sylda
Q1 - JCSat-17 - Ariane 5 ECA - Kourou ELA-3 (or Q4 2019) above the Sylda
H1 - BSAT-4b - Ariane 5 ECA - Kourou ELA-3 below the Sylda
Early Q2 - Galaxy 30, MEV-2 - Ariane 5 ECA - Kourou ELA-3 above the Sylda

EDITs 10/17
JCSat-17                ~6500 kg  (my estimate from masses of the other two LM-2100 (modernized) satellites launched thus far)
GEO-KOMPSAT-2B    3200 kg
BSAT-4b                 3520 kg

For MEV-2’s initial mission, Space Logistics has contracted with Intelsat Satellite LLC (“Intelsat”) to provide life extension service to the Intelsat 1002 (“IS-1002”) spacecraft, operating the satellites as a CVS.

The Airbus Eurostar-3000 satellite "Intelsat 10-02" at 1 ° W was launched on 06/16/2004 with a Proton-M.
Apparently still healthy, only the fuel is low.

Total lockdown has been extended in France until May 11.
<snip>
Ariane 5 needs more than a month to launch, so the date of June 3 cannot be held.
So for now we have VV-16 NET May (at the earliest on May 21st), and VA-253 NET June.

Launcher components for #Arianespace’s next #Ariane5 mission, Flight #VA253, have been delivered to French Guiana by the MN Toucan roll-on/roll-off ship, enabling preparations for liftoff this summer. @INTELSAT and @Maxar (for B-SAT) are the customers. @ArianeGroup

Quote from: Arianespace
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.

Northrop Grumman’s Second Mission Extension Vehicle and Galaxy 30 Satellite Begin Launch Preparations in French Guiana

News Releases
June 30, 2020

DULLES, Va. – June 30, 2020 – Northrop Grumman Corporation (NYSE: NOC) announced today the arrival of the company-built Galaxy 30 (G-30) spacecraft for Intelsat and the Mission Extension Vehicle 2 (MEV-2) at the launch site in Kourou, French Guiana. The vehicles are scheduled to launch late July 2020, in a stacked configuration onboard an Ariane 5 rocket.

“These satellites are excellent examples of our established leadership and innovation in the industry,” said Frank DeMauro, vice president and general manager, tactical space systems, Northrop Grumman. “The Galaxy 30 spacecraft will fill a critical need for Intelsat, while our second MEV will provide game-changing life extension services and continue to define a new market.”

Galaxy 30 (G-30) is the 11th Northrop Grumman-built satellite purchased by Intelsat and the first in its Galaxy fleet replacement program, dedicated to video distribution and broadcast services. G-30 carries a C-band payload and will be integral to the U.S. C-band spectrum transition plan that Intelsat is collaborating on with the Federal Communications Commission. Additionally, G-30 includes 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. G-30 is based on Northrop Grumman’s flight-proven GEOStar-2 platform.

Intelsat also recently selected Northrop Grumman to build two C-band satellites, which are the 12th and 13th purchased from the company.

The Mission Extension Vehicle is the industry’s first satellite servicing vehicle, designed to dock with geostationary satellites whose fuel has nearly depleted. Once docked, MEV uses its own thrusters and fuel supply to control the orbit of the customer satellite. When the customer no longer desires MEV’s service, it will undock and move to a new client’s vehicle.

The company’s first Mission Extension Vehicle, MEV-1, launched October 9, 2019, and completed its historic docking with the Intelsat 901 spacecraft February 25, 2020. This marked the first time two commercial satellites have docked in orbit. IS-901 resumed communications services April 2, 2020.

MEV-2 will dock with the Intelsat 1002 (IS-1002) in early 2021. MEV-2 is the second Mission Extension Vehicle supplied by Space Logistics LLC, a wholly owned subsidiary of Northrop Grumman.

The launch planning for Ariane 5’s Flight VA253 – to be performed for operators Intelsat and B-SAT – was confirmed on July 28. The two Intelsat satellites arrived at the Spaceport in French Guiana on Saturday, June 27. Arrival of the BSAT-4b satellite is expected on July 1st. The availability of this launch – with its eastward trajectory towards geostationary orbit – is not affected by the high-altitude winds currently observed above the Guiana Space Center in relation to the range safety rules.

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

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.

 Ariane 5’s July mission will be followed by Vega in August
Arianespace’s scheduling of Flight VA253 as its next launch comes after the decision to postpone Europe’s first small-sat rideshare mission with the light-lift Vega launcher until August 17.  This shift resulted from the persistence of exceptionally unfavorable winds at altitude over the Spaceport, resulting in multiple postponements of the liftoff despite a full availability the launcher and its 53 satellite passengers on the Small Spacecraft Mission Service (SSMS) Proof of Concept flight.

The new launch date for Vega Flight VV16 in August was decided in anticipation of a more favorable weather forecast, which is based on modeling of the winds. The interim period will be used to recharge the Vega launcher’s batteries, as well as those of the mission’s satellites.

Flight VV16 will place its payload of seven microsatellites and 46 smaller CubeSats into Sun-synchronous orbits. The unfavorable high-altitude winds on this mission’s northward trajectory from the Spaceport in French Guiana will not affect Flight VA253, as the Ariane 5 will be flying an eastward trajectory towards geostationary transfer orbit.

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.

“Double vision” as Galaxy 30 and MEV-2 are readied for Ariane 5’s next mission


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.
