Kourou, French Guiana (ESA) Aug 25, 2016
The diversity of Arianespace launch services available to commercial and institutional customers is underscored by the current mission preparations for flights that will orbit Earth observation platforms, telecommunications relay spacecraft and global navigation satellites from the Spaceport.
During the coming four months from French Guiana, these flights will deliver satellites of varying weights and sizes to:
+ Medium-Earth orbit for improved positioning and timing information in a European program;
+ Geostationary transfer orbit, providing advanced relay capacity for a leading U.S.-based telecommunications operator; and
+ Sun-synchronous orbit for high-resolution imaging with Peru's first Earth observation satellite.
Ariane 5 comes ashore for its trip to medium-Earth orbit
Scheduled for liftoff in November, this Ariane 5 will carry a cluster of four European navigation system spacecraft, further expanding the Galileo constellation that has been created with satellites orbited in pairs by previous Arianespace missions using Soyuz launchers.
Among the components delivered by the MN Colibri were Ariane 5's cryogenic core stage, its EPS storable propellant upper stage, and the payload fairing for Arianespace's November mission - designated Flight VA233 in the company's launcher family numbering system. These elements were unloaded at Pariacabo Port on the Kourou River for their transfer to the nearby Spaceport.
Flight VA233 will use an Ariane 5 ES version, which was flown on Arianespace launches in the past that deployed Europe's 20,000-kg.-class ATV resupply vehicle into low-Earth orbit for rendezvous and docking with the International Space Station.
While Flight VA233's lift performance will be significantly less than with the ATV - the four Galileo satellites have a liftoff mass of some 740 kg. each, plus 447 kg. for their dispenser system - the Ariane 5 will carry its payload to a much higher medium-Earth orbit altitude of approximately 23,200 km. To date, Arianespace has orbited 14 Galileo spacecraft on seven previous Soyuz missions; the most recent was conducted in May.
An Arianespace "double" mission to geostationary transfer orbit
This Ariane 5 ECA version was transferred today to the Spaceport's ELA-3 launch zone. With a liftoff during a 45-minute launch window opening at 6:55 p.m. local time in French Guiana on August 24, Intelsat 33e and Intelsat 36 are to be deployed into geostationary transfer orbit during a 41-minute mission.
Flight VA232 marks Arianespace's sixth launch so far in 2016, and the fourth since January utilizing an Ariane 5.
Vega's September launch to Sun-synchronous orbit
PeruSAT-1 is equipped with a silicon carbide optical instrument system to image Earth at 70 cm. resolution, and will serve as Peru's first Earth observation satellite. With a liftoff mass of approximately 450 kg., PeruSAT-1 will operate from Sun-synchronous orbit.
The Vega mission with PeruSAT-1 is designated Flight VV07 in Arianespace's launcher family numbering system, signifying the light-lift vehicle's seventh launch overall, and its first in 2016 from Europe's Spaceport in French Guiana.
