Ariane 5’s fifth mission of 2010 orbited a dual payload of the Intelsat 17 and HYLAS 1 telecommunications satellites today, marking the 40th consecutive success for Arianespace’s workhorse heavy-lift launcher.

Since the start of 2010, Ariane 5 has orbited 10 large telecommunications satellites out of the 17 total launched worldwide. 

Intelsat 17 was the 51st satellite lofted by Arianespace for Intelsat, while HYLAS 1 is the first satellite deployed by Arianespace for Avanti Communications.


Arianespace’s fifth Ariane 5 mission of 2010 was given the go-ahead today for its November 26 liftoff with a dual payload of the Intelsat 17 and HYLAS 1 satellites.

With the successful review, Ariane 5 is cleared for its rollout from the Spaceport’s Final Assembly Building to the ELA-3 launch zone, where it will be readied for liftoff on Friday during an early launch window that opens at 3:39 p.m. local time in French Guiana and continues to 6:54 p.m.

The Spaceport validates propellant and fluid delivery processes for Soyuz’ upcoming service introduction

The validation of delivery methods for propellant and fluids used in Soyuz operations at the French Guiana launch site is nearing completion as preparations continue for this medium-lift vehicle’s maiden flight next year. The means of supplying liquid oxygen, liquid nitrogen and hydrogen peroxide to the Soyuz launch pad have now been confirmed, while final evaluations for the delivery of kerosene are to be carried out in November and December. Liquid oxygen and kerosene are the propellants for Soyuz’ first, second and third stages; liquid nitrogen provides onboard pressurization and inerting; while hydrogen peroxide is used to drive gas turbines that power the launcher’s turbopumps.

The first Vega hardware moves to the launch pad

A representative P80 first stage for Vega has rolled out to the launch pad in French Guiana, marking the initial step in combined testing of this lightweight vehicle with its ground-based infrastructure.

The P80 stage was developed by Italy’s Avio for Vega program prime contractor ELV, and is one of the largest, most powerful one-piece solid-propellant boosters ever built. It utilizes a novel filament-wound case, and will burn 88 metric tons of propellant during a powered flight lasting 109 seconds.

Arianespace selected to launch initial satellite for Azerbaijan

The International Relations and Accounting Center of the Ministry of Communications and Information Technologies of the Republic of Azerbaijan has chosen Arianespace to launch the country’s first communications satellite.

The spacecraft – to be orbited during a heavy-lift Ariane 5 mission by the end of 2012 – will be built by Orbital Sciences Corporation using a STAR-2 platform. It is to deliver a wide range of communications services for all of Azerbaijan, as well as Central Asia, Europe, Middle East and Africa.
