Site advantages

The Spaceport has a track record of successful launch operations, industry milestones and other achievements

Origins

France made the decision to build its new launch base at French Guiana in 1964, shifting the country’s nascent operations from the French Sahara to South America.

Selection of what was to become the Guiana Space Center – also known as Europe’s Spaceport – came after detailed parametric studies of 14 potential locations pre-selected from a worldwide list.

After the early experience gained through more than 500 launches of balloons, sounding and experimental rockets, the Spaceport ranks today as one of the most modem and capable space base facilities, with over 220 Ariane flights performed from this facility. Its scope was further expanded when Vega entered service in early 2012, followed by the Vega C launcher in July 2022.

The early days

The Spaceport became operational in April 1968 with the launch of a liquid propellants French Veronique sounding rocket. In parallel with several hundreds of solid propellant sounding rockets and balloons, eight missions with France’s Diamant B launch vehicle were performed beginning in March, 1970, followed in November, 1971 by the European Europa launcher.

Management and technical difficulties with Europa led to a complete overhaul of Europe’s launcher activities – from which the Ariane program was born.

Ariane enters service

The ELA-1 launch complex was the first major launch facility used for Ariane. This site originally was built for the Europa vehicle, and had a second life when adapted for Ariane after the Europa program ended.

The facility included a launch control center and the launch zone. In the launch zone, Ariane vehicles were assembled on the launch pad and protected by a mobile service tower during the build-up and satellite integration process. The mobile tower was rolled back prior to liftoff.

Specific payload preparation facilities were built to allow spacecraft preparation, then hazardous propellant fueling, in ultra-clean conditions: the EPCU1.

The ELA-1 complex entered service for Ariane on December 24, 1979 with the first successful flight of an Ariane 1 on Flight L01. During its operational lifetime, a total of 25 Ariane 1, Ariane 2 and Ariane 3 vehicles were launched from ELA-1. The final liftoff from ELA-1 occurred on July 11, 1989, when an Ariane 3 carried the Olympus satellite on the 32nd flight of an Ariane vehicle.

This historic facility is now being given a second life, as the ELA-1 site has been refurbished and modernized for use as the launch complex for Arianespace’s new Vega lightweight launcher.

Ariane 4 becomes a benchmark

From its service entry in 1986, the Spaceport’s ELA-2 launch complex supported some Ariane 2 and 3 then the Ariane 4 vehicle family’s fast-paced launch schedule from its on-target maiden flight in June 1988 through the final Ariane 4 mission in February 2003.

The complex consisted of two areas: the launcher preparation zone and the launch zone. These two areas were separated by one kilometer, allowing one launcher to undergo final checkout and payload integration in the launch zone while a second was being assembled in the launcher preparation zone.

A second larger series of spacecraft preparation and fuelling facilities also were built to accommodate the larger and heavier Ariane 4-class spacecraft: the EPCU2.

ELA-2 was designed for 10-to-11 launches per year with an interval of one month between successive missions. Arianespace maintained a high operational mission rate throughout the Ariane 4 program to meet commercial demand. A total of 116 Ariane 4s were launched from ELA-2, successfully orbiting 158 primary payloads (plus 24 auxiliary passengers) with a combined mass of well over 400 metric tons.

Entering the heavy-lift era

The ELA-3 launch facility was developed for Ariane 5, with the first mission performed from this site in 1996. Its design benefitted from Arianespace’s extensive launch operations experience, and encompasses a launch vehicle preparation zone with separate Ariane 5 integration and final assembly buildings, the launch zone, as well as a dedicated facility for the production of propellant used in the center and aft segments of Ariane 5’s two solid rocket boosters. All of these areas are connected by a rail line system, facilitating the transfer of launcher components and the completed vehicles.

A dedicated building also was created by Arianespace to allow preparation for, then fueling of, the spacecraft in the same area, without needing to put them in a container between these phases: the S5 complex.

The S5 and ELA-3 facility’s ability to support a sustained mission rate is regularly demonstrated by the six to seven Ariane 5 launches performed by Arianespace annually, with a peak of nine flights conducted during a 12-month period. The heavy-lift Ariane 5 lofts single and dual-passenger payloads that range from telecommunications satellites and Earth observation platforms to scientific spacecraft and deep space exploration probes.

Beginning in 2008, the Ariane 5’s missions were expanded to include launches of the 20-ton European-built Automated Transfer Vehicle (ATV) cargo resupply spacecraft, bringing the Spaceport into the limited “club” of space centers that serve cosmonaut and astronaut crews aboard the International Space Station.

Soyuz came to the Spaceport

Following the invasion of Ukraine by Russia and the Russian Authorities unilateral decision to withdraw from Europe’s spaceport Soyuz operation is now suspended following. As part of the mandate given by the ESA Member States to Arianespace, the exploitation of the Soyuz launcher is governed by France/Russia inter-governmental agreement and ESA / Russian Federal Space Agency agreement.

Preparations for Soyuz’ introduction at the Spaceport began in April 2004, as construction started on the massive ELS launch complex for this Russian-built workhorse medium-lift vehicle. With this new facility, the Spaceport’s operational area is extended northward along the French Guiana coast.

The ELS facility includes a launcher integration building (known by its Russian designation: MIK), launch control center, and the launch pad with its massive 149 meter-wide x 123 meter-long flame duct, as well as all the associated propellant facilities.

Maintaining the long-established processing flow used for Soyuz vehicles at Baikonur Cosmodrome in Kazakhstan and Plesetsk Cosmodrome in northern Russia, launchers at the Spaceport are integrated horizontally in the MIK. This involves the mating of Soyuz’ first stage strap-on boosters to the Block A core second stage, followed by installation of the Block I third stage. The assembled Soyuz is then transferred horizontally by rail to the launch pad, where it is erected to the vertical position.

One of the Soyuz launch site’s distinctive features at the Spaceport is its purpose-built 52-meter-tall mobile service gantry, which enables payloads to be installed atop the Soyuz vehicle while in its vertical position — as is the practice in Arianespace operations and for other Western launchers. This represents a change from the horizontal Soyuz payload integration process at the Baikonur and Plesetsk Cosmodromes, with the gantry rolled into position on the launch pad — providing protection during payload installation and during final checkout of the vehicle. On launch day, the gantry is rolled back 80 meters to its parked position 1hr., 10 min. before the scheduled liftoff.

Soyuz entered service with Arianespace at the Spaceport in October 2011 with an on-target maiden flight that orbited the first two European Galileo navigation satellites. In preparation for the historic introduction of this longest-operating launcher to the world’s most modem launch base, a 1:1 scale exercise with a flight-like Soyuz vehicle was performed in April-May 2011 at the Spaceport that culminated in a highly realistic mission countdown going through all steps of preparing and fueling a fully-integrated Soyuz up to its simulated launch.

Completing Arianespace’s launcher family with Vega and Vega C

Beginning its third life, the Spaceport’s refurbished ELA-1 launch site began hosting launches of the light weight Vega launcher in 2012, providing Arianespace with a comprehensive family of vehicles for its customers’ mission requirements.

Vega is tailored to carry the growing number of small scientific spacecraft and other lighter-weight payloads under development or planned worldwide.

Like Ariane 1 to 3, the build-up of Vega is performed on its launch pad, where the solid propellant first, second and third stages are stacked, followed by installation of a bi-propellant Attitude and Vernier Upper Module (AVUM), then topped with the payload encapsulated in the fairing. A completed Vega stands approximately 30 meters tall, and is protected during the integration process by a mobile gantry. On launch day, the gantry is rolled back to its parked position, 70 meters away from the launcher, 2 hr., 40 min. before the scheduled liftoff.

On July 13, at 10:13 am local time at Europe’s Spaceport, in French Guiana, the first Vega C, the new European launcher designed and manufactured by AVIO, was successfully launched under the supervision of ESA. Following the success of its inaugural flight, Vega C will now begin its operational phase, under the responsibility of Arianespace, with a target of at least four launches per year and a fast-growing backlog.
