Soyuz Flight VS08

Launch of Soyuz and 03b satellites network

O3b Networks’ mission to bridge the digital divide marked a significant step forward with today’s Arianespace Soyuz flight that deployed its next four connectivity satellites – which will complete the basic constellation for this customer’s pioneering connectivity service and help make the O3b vision a reality.

The launch success – which had a total payload lift performance of more than 3,200 kg. – continues the partnership between Arianespace and O3b Networks, and builds upon the on-target Soyuz mission that orbited O3b’s initial four spacecraft in June 2013.

Soyuz is the medium-lift member of Arianespace’s launcher family operated from French Guiana, joined by the heavy-lift Ariane 5 and lightweight Vega. For today’s mission, it delivered O3b Networks’ satellites during a flight lasting 2 hours and 22 minutes – which included three burns of the Fregat upper stage, with the four passengers released in two phases from a dispenser system.

The latest O3b Networks connectivity satellites are equipped with Ka-band transponders, and will be positioned at a medium-orbit altitude of 8,062 km. Along with the four spacecraft launched last year, they form the network framework to provide billions of consumers and businesses in nearly 180 countries with low-cost, high-speed, low-latency Internet and mobile connectivity.

O3b Networks’ satellite constellation is fully scalable to meet market demand and operates from a medium-orbit altitude of 8,062 km. From this low altitude, latency is dramatically reduced – bringing it on par with a long-haul fiber transmission. The O3b spacecraft were designed, integrated and tested by Thales Alenia Space.

Arianespace continues to set the standard in launch services worldwide. With the Soyuz, Ariane 5 and Vega launchers fully operational at the Spaceport in French Guiana, it is the only launch services company capable of delivering any payload into any orbit – from the smallest spacecraft to the largest geostationary satellites, as well as satellite clusters for constellations and cargo missions to the International Space Station.

Second release in target orbit of the 03b 1 and 3 satellites

Today’s Soyuz success marked the medium-lift vehicle’s eighth flight from the Spaceport since its 2011 introduction at French Guiana, as well as the fifth Arianespace mission from this equatorial launch site in 2014.

The next mission in Arianespace’s 2014 manifest is the July 24 Ariane 5 flight that will deliver Europe’s fifth, and final, Automated Transfer Vehicle (ATV) for servicing of the International Space Station. The ATV program – managed by the European Space Agency (ESA) – is part of Europe’s contribution to the International Space Station’s operation.
