An agreement has been signed with Arianespace at the launch of the third Copernicus Sentinel-1 satellite. Scheduled to launch ESA’s new Vega-C rocket from Europe’s Spaceport in French Guiana in early 2023, Sentinel-1C will continue the critical task of providing critical radar images for a wide range of services. , applications and sciences – all. which is for the public good.

Taking advanced radar technology to provide day and night images of the world, the Sentinel-1 mission not only raised the bar for spaceborne radar, but also set the stage for Copernicus, world view. Part of the European Union’s aerospace system.

Copernicus has been the largest provider of geological data in the world for a number of years now. The Sentinel mission provides critical information and a wide range of services provided through Copernicus to help solve some of today’s most important environmental issues such as food insecurity, inflation. Sea level rise, snowfall, natural disasters, and extreme weather conditions.

In April 2014, Copernicus Sentinel-1A was the first satellite launched for this amazing environmental project.

Copernicus Sentinel-1C in testing

With the mission having two identical satellites orbiting 180 ° apart to capture Earth with a frequency of six days, and even covering daily at high latitudes, it established Sentinel-1B was launched in April 2016.

Sentinel -1A is longer than its seven -year design life – but it remains strong and is expected to be in service for several years to come.

Sentinel-1B, on the other hand, is not currently available due to a technical anomaly, so it is important to get Sentinel-1C into orbit and work as soon as possible.

The agreement, signed by ESA today for the European Union by ESA’s Director of Earth Observation Programs, Simonetta Cheli, Director of Space Transportation, Daniel Neuenschwander, and Director of Arianespace, Stéphane Israel, to confirm the flight of Copernicus Sentinel-1C in the air. a Vega-C rocket from French Guiana.

Simonetta Cheli said, “All of ESA’s Sentinel satellites for the European project have been developed and built on major projects and at the heart of this global environmental project. The Sentinel-1 mission is key to delivering to radar data to monitor sea ice, to monitor icebergs and glaciers, subsidence, oil spills and more.With so many users relying on this data, great excitement we are recording the launch for Sentinel-1C on an ESA Vega-C rocket, increasing ESA’s access to the air.

Stéphane Israël added, “We are very proud of this new broadcast agreement with the European Space Agency, which oversees the Copernicus space agency, pointing to our long -term partnership. For Arianespace, this is a new symbol of that. relied on the Vega system and reaffirmed its ability to meet the new needs of users. “

The artist’s idea for Vega-C was in the early stages

Vega-C is more powerful than its predecessors and capable of a wide range of missionary styles. It is a single body rock about 35 m high with a capacity of 210 tonnes. It can carry around 2200 kg in a 700 km-polar orbit direction, meeting the needs of European companies and industry.

The Vega-C rocket will deploy the Sentinel-1C satellite, which weighs about 2.3 tonnes, in a Sun-synchronous orbit at an altitude of about 690 km.

Ramón Torres, Director of ESA’s Sentinel-1, said, “Sentinel-1C is in the final stages of its test deployment. This will include environmental tests where the entire aircraft will be mechanically demonstrated. and the sound that will be seen during the release, as well as the thermal, vacuum and radiation environment from which the satellite will operate for years to come.

“As a result, full approval is planned for the flight by the end of 2022”.
