Call for interest: Sentinel-1C launch media event

The third Copernicus Sentinel-2 satellite, Sentinel-2C, has launched aboard the last Vega rocket, flight VV24, from Europe’s Spaceport in French Guiana. The rocket lifted off on 5 September at 03:50 CEST (4 September 22:50 local time).
Sentinel-2C will provide high-resolution data that is essential to Copernicus – the Earth observation component of the European Union’s Space programme. Developed, built and operated by ESA, the Copernicus Sentinel-2 mission provides high-resolution optical imagery for a wide range of applications including land, water and atmospheric monitoring.

The mission is based on a constellation of two identical satellites flying in the same orbit but 180° apart: Sentinel-2A and Sentinel-2B. Together, they cover all of Earth’s land and coastal waters every five days. Once Sentinel-2C is operational, it will replace its predecessor, Sentinel-2A, following a brief period of tandem observations. Sentinel-2D will eventually take over from Sentinel-2B.

Sentinel-2C was the last liftoff for the Vega rocket – after 12 years of service this was the final flight, the original Vega is being retired to make way for an upgraded Vega-C.

The third Copernicus Sentinel-2 satellite launched from Europe’s Spaceport in French Guiana aboard the final Vega rocket on 5 September at 03:50 CEST (4 September 22:50 local time).

After a successful launch, Sentinel-2C separated from its Vega rocket at approximately 04:48 CEST. Around 14 minutes later, at 05:02 CEST, ESA’s ESOC mission operations centre in Darmstadt, Germany, received the all-important first signals from the satellite indicating that it had safely arrived in orbit.

Giovanna Manca, Vega launch complex operations manager for Avio, Fulvio Spaziani Brunella, Site manager for Avio, Claude Legrand, Quick-look telemetry display technical authority for Arianespace, Renato Lafranconi, Vega programme manager at ESA, and Francesca Diciolla, Environmental safety manager for Avio explain their roles in the Vega story.

The last Vega flight ended three Sentinel 2 launches, the Sentinel-2A and Sentinel-2B satellites were launched on Vega marking a logical conclusion to Vega’s stellar roster of satellites launched. Other missions launched by the small and nimble rocket over its lifetime are flagship ESA missions such as technology demonstrator Proba-V, wind monitoring satellite Aeolus, the reentry vehicle IXV and a forerunner to LISA that will measure gravitational waves in space.

Vega ensured that Europe has a versatile, independent access to space, complementing the Ariane family of rockets to launch any satellite to any orbit – continuing with Vega-C and Ariane 6.

Vega joined the family of launch vehicles at Europe’s Spaceport in French Guiana in 2012. At 30-m tall the rocket weighs 137 tonnes on the launch pad and reaches orbit with three solid-propellant powered stages before the fourth liquid-propellant stage takes over. By rocket standards Vega is lightweight and powerful, the first three stages burn through their fuel and bringing Vega and its satellites to space in just six minutes.

Specialising in launches of small satellites to orbits flying over Earth’s poles, Vega has an impressive roster of missions that it has sent to space. Flagship ESA missions that flew Vega include technology demonstrator and Earth vegetation watcher Proba-V and wind-monitoring satellite Aeolus. Vega’s heaviest payload launched was the 1906-kg LISA Pathfinder, a forerunner to LISA that will measure gravitational waves in space..

In 2015 Vega launched three ESA missions in one year, including reentry demonstrator IXV that showed Europe has the technology to launch a vehicle to space and return it safely to Earth. In less than two hours Vega accelerated IXV to speeds of 27 000 km/h at a height of 412 km before the reentry vehicle splashed down in the Atlantic Ocean. This demonstration mission was a precursor to the reuseable Space Rider spacecraft that will offer regular access to space for research and in orbit validation and demonstration missions and is paired with the Vega family of launchers.

With its Vespa secondary payload adapter, first launched in 2013 on Vega’s second flight, Vega offered different options for payload  ride-sharing where multiple satellites are launched on one rocket. In 2020 a variant of Vespa called the Small Spacecraft Mission Service transported over 50 satellites at once to orbit.

Sentinel-2C is the last payload that the Vega rocket launches into space – after 12 years of service. Fittingly the Sentinel-2A and Sentinel-2B satellites were launched on Vega marking a logical conclusion to Vega’s stellar roster of satellites launched.
