EUTELSAT 5 West B will be located at 5° West, a key video neighborhood addressing French, Italian and Algerian broadcast markets while MEV-1 will deliver on-orbit servicing satellite life-extension through Northrop Grummans SpaceLogistics LLC.
The Proton Breeze M, utilising a 5-burn SSTO mission design, launched from Pad 39 at the Baikonur Cosmodrome on 9 October at 15:17 local time. The satellites are both manufactured by Northrop Grumman and based on the GeoStar-2 (Eutelsat 5 West B) and GeoStar-3 (MEV-1) platforms. The two spacecraft, making up the Integrated Payload Stack, weighed 5,190 kg at liftoff, and were separated 15 hours, 36 minutes (Eutelsat 5 West B) and 15 hours, 54 minutes (MEV-1) after liftoff. Operators at the Northrop Grumman operations centre in Dulles, Virginia acquired the spacecrafts first telemetry from orbit shortly after separation.
Eutelsat 5 West B is a Ku-band satellite that will be located at 5° West, a key video neighborhood addressing predominantly French, Italian and Algerian broadcast markets. The new satellite will provide business continuity and improved quality for these markets via a Ku band payload of 35 equivalent 36 MHz transponders connected to three service areas. Switchable transponders will also increase commercial flexibility.
MEV-1 will deliver on-orbit servicing satellite life-extension through Northrop Grummans wholly-owned subsidiary SpaceLogistics LLC. MEV-1 will dock to client vehicles in geosynchronous orbit to provide attitude and orbit control of the combined vehicle stack. MEV-1 has the ability to dock and undock several times during its 15-year design life, allowing it to service multiple customers. SpaceLogistics LLCs initial service, using MEV-1, will extend the life of the Intelsat 901 satellite for five years.
Since its maiden flight in 1965, the workhorse Proton vehicle has demonstrated its versatility, maturity and performance to inject spacecraft into a wide variety of orbits for a diverse customer base. The Proton Breeze M vehicle is developed and built by Khrunichev Research and Production Space Center (Khrunichev) of Moscow, Russias premier space industry manufacturer and majority shareholder in ILS.
ILS President Kirk Pysher said: ILS would like to extend our heartfelt congratulations to the entire Eutelsat, Northrop Grumman, SpaceLogistics and Airbus Defence & Space teams on this outstanding success. I would also like to thank the teams at Roscosmos, Glavkosmos, GK Launch, Khrunichev, ILS and all of the various contractors and suppliers who support Proton and made this successful mission possible. We are all very thankful and proud to play an important role in our customers continued success.
Pysher added: This mission is Protons 18th consecutive success bringing Protons five-year reliability to 95.6%. With todays added demonstration of Proton dual launch capability, ILS looks forward to supporting a broad range of changing spacecraft requirements.
Yohann Leroy, Deputy CEO and Chief Technical Officer at Eutelsat, said: Eutelsat is delighted to be back at Baikonur for another successful launch. Our congratulations to ILS and Khrunichev for this top-class dual stacked launch! I would like also to thank our partners Northrop Grumman and Airbus Defence and Space for their collaboration in creating this technological gem, that will soon serve the French, Italian and Algerian markets with the highest quality video broadcasting. I would also like to welcome aboard EUTELSAT 5 West B the European GNSS Agency (GSA)s EGNOS payload, set to greatly improve the accuracy of geolocation systems such as GPS or Galileo.
Tom Wilson, President, SpaceLogistics LLC added: The launch and eventual docking of MEV-1, the industrys first life extension vehicle, demonstrates Northrop Grummans and SpaceLogistics ability to innovate and deliver game-changing technology. We are proud to have partnered with the ILS and Eutelsat teams who worked long and hard to ensure mission success. MEV-1 marks the first step towards introducing even more advanced on-orbit servicing capabilities and services for our customers.
