Mission Description

Flight VV08: A new Vega mission at the service of earth observation

For its 10th launch of the year – and the eighth to be performed by the Vega launcher since its first liftoff from the Guiana Space Center in 2012 – Arianespace will orbit the GÖKTÜRK-1 satellite in the framework of a Telespazio turnkey contract with the Undersecretariat for Defence Industries of Turkey (SSM).

As a multi-purpose launch vehicle that already has demonstrated its capabilities during the seven initial missions, Vega is now fully operational in commercial service – and will be performing its fifth flight at the service of Earth observation. With Flight VV08, Turkey becomes a new export customer for this latest member of Arianespace’s launcher family.

Payload

GÖKTÜRK-1

GÖKTÜRK-1 is the first Turkish governmental satellite for Earth observation. It also is the sixth satellite to be launched by Arianespace for Turkey, following five Türksat-series telecommunications spacecraft from 1994 to 2008.

GÖKTÜRK-1 is a very high-resolution optical Earth observation satellite.
Its images are intended for civilian and military applications. The satellite will be injected in a Sun-synchronous orbit at an altitude of approximately 700 km. GÖKTÜRK-1 is capable of imaging the entire globe in 72 hours.

Telespazio – as prime contractor of the GÖKTÜRK-1 program under terms of a 2009 agree-ment signed with the Undersecretariat for Defence Industries of Turkey in Ankara (SSM) – is responsible for the satellite’s integration and the associated ground segment.

SSM is the 55th operator to select Arianespace for the launch of its first satellite.

Thales Alenia Space and its Turkish partners – including the companies TAI A.S., Aselsan A.S., Tubitak Bilgem, Roketsan A.S. and TR Tecnoloji – built GÖKTÜRK-1 based on the PROTEUS spacecraft platform.

GÖKTÜRK-1 will be 145th Thales Alenia Space-produced satellite launched by Arianespace.

Eleven other satellites from this spacecraft manufacturer are in Arianespace’s launch services order book: SENTINEL-2B, SGDC, TELKOM-3S, KOREASAT-7, COMSAT NG 1, four satellites for O3b, along with two “undisclosed” payloads.

Flight Events at a Glance

Following liftoff from the Guiana Space Center, the powered phase of Vega's first three stages will last 6 minutes, 36 seconds.

After this first phase, the launcher’s third stage will separate from the upper composite, which includes the AVUM upper stage, a payload adapter and the satellite. The lower three stages will fall into the sea.

The AVUM upper stage will ignite its engine for the first time, operating for about six minutes, 20 seconds followed by a ballistic phase lasting approximately 40 minutes.

The AVUM stage will then reignite its engine for approximately one minute, 42 seconds, prior to releasing the GÖKTÜRK-1 satellite about two minutes after the engine is shut down.

The GÖKTÜRK-1 satellite will be released 57 minutes, 19 seconds after liftoff.

Latest Mission Update

The Vega launcher is complete for next week’s Arianespace mission with GÖKTÜRK-1

The eighth Vega lightweight launcher to be operated from the Spaceport in French Guiana has been fully assembled and “topped off” with the GÖKTÜRK-1 optical satellite payload, readying it for Arianespace’s mission to Sun-synchronous orbit on December 5.

Designated Flight VV08 in Arianespace’s numbering system, this Vega launch is to deploy GÖKTÜRK-1 during a mission lasting just under two hours.

With Vega now in full commercial operation, Flight VV08 will mark the vehicle’s fifth launch at the service of Earth observation.

High-resolution imaging for Turkey

GÖKTÜRK-1 has been built as Turkey’s first governmental satellite for Earth observation, providing very high-resolution images for both civilian and military applications.

Telespazio is prime contractor of the GÖKTÜRK-1 program under terms of an agreement signed with the Undersecretariat for Defence Industries (SSM) of Turkey. SSM is the 55th operator to select Arianespace for the launch of its initial satellite.

Thales Alenia Space and its Turkish partners – including the companies TAI A.S., Aselsan A.S., Tubitak Bilgem, Roketsan A.S. and TR Tecnoloji – built GÖKTÜRK-1 based on the PROTEUS spacecraft platform.

A morning liftoff for Vega

Liftoff of Vega from the Spaceport’s SLV launch site is set at exactly 10:51:44 a.m., local time in French Guiana on December 5 (13:51:44, Universal Time), with the launcher carrying a total payload of approximately 1,140 kg.

This latest Vega mission underscores the capabilities of Arianespace’s lightweight member in its launcher family operated from French Guiana – complementing the medium-lift Soyuz and heavyweight Ariane 5 in an offer that covers a full range of launch services capabilities.

Vega was developed in a European Space Agency (ESA) program jointly funded by Italy, France, Spain, Belgium, the Netherlands, Switzerland and Sweden. Design authority and industrial prime contractor for the launch vehicle is Italy’s Avio, operating through its Italian subsidiary ELV (in which the Italian space agency ASI has a 30 percent stake).
