In short: Watch the 2015 liftoff of Sentinel-2A, a satellite designed to monitor our planet's health. This video captures the launch of a critical tool for environmental monitoring and humanitarian relief.

Launched on June 23, 2015, from the European Spaceport in French Guiana, Sentinel-2A is part of a two-satellite constellation for the Copernicus programme. It features a high-resolution multispectral imager with 13 spectral bands, providing a unique perspective on land and vegetation.

The data gathered serves practical, high-stakes purposes: optimizing agricultural and forestry practices, managing food security, and monitoring pollution in coastal waters and lakes. Additionally, its ability to image floods, landslides, and volcanic eruptions provides vital information for disaster mapping and humanitarian aid.
