Preparing to launch ‘colour vision’ satellite
The latest satellite for the European Commission’s environmental Copernicus programme has arrived safe and sound in French Guiana for launch on 12 June. Carrying a multispectral imager, Sentinel-2A is set to give us a new perspective of our land and vegetation.
Greeted by pouring rain and equatorial warmth, the huge Antonov cargo aircraft that carried the Sentinel from Germany touched down at Cayenne airport in the early morning of 21 April.
Sealed in its special air-conditioned transport container, the satellite was carefully unloaded along with three other containers of support equipment. A convoy of lorries then drove the precious cargo to Europe’s Spaceport near Kourou, about 60 km away.
Once inside the cleanroom, the satellite was left in its container overnight to rest.
Offering ‘colour vision’ for Copernicus, Sentinel-2A combines high-resolution and novel multispectral capabilities, a first for ESA. With a 290 km-wide coverage path and frequent revisits, Sentinel-2 will deliver views of Earth’s vegetation and changing lands in unprecedented detail and accuracy.
The mission will mainly provide information for agricultural and forestry practices and for helping manage food security. Satellite images will be used to determine key information about plants, such as chlorophyll and water content. This is particularly important for predicting yields effectively and applications related to Earth’s vegetation.
As well as monitoring plant growth, the mission will map changes in land cover and monitor the world’s forests. It will also provide information on pollution in lakes and coastal waters.
Images of floods, volcanic eruptions and landslides contribute to disaster mapping and help humanitarian relief efforts.
Yesterday, cranes were used to open the container and unveil the satellite and position it. Now on its stand, Sentinel-2A will be connected to its ‘electrical ground support equipment’, which is an essential piece of equipment for testing.
ESA’s Launch Campaign Manager, Paolo Laberinti, said, “It’s great to see our baby safe and well after its long journey.
“Every eventuality has to be considered when transporting such delicate cargo, so the journey was planned with every detail in mind to ensure Sentinel-2A was well looked after.
