How Europe is preparing its next great eye in the sky

Sentinel-2A: Ready to launch · 3:07 · Video: European Space Agency, ESA · Watch at the source

In short: This video captures the final preparations for Sentinel-2A as it readies for launch from French Guiana. Discover how this mission will provide high-resolution imagery to monitor the Earth's vital ecosystems and support emergency services.

Launched from Europe's Spaceport on a Vega launcher, Sentinel-2A is the second satellite in the Copernicus programme. It uses an optical payload featuring visible, near infrared, and shortwave infrared sensors to capture data across a 290 km swath width.

The mission relies on a constellation of two satellites—Sentinel-2A and its sister Sentinel-2B—to ensure consistent coverage and revisit requirements. By monitoring land, soil, water, and coastal areas, the mission provides essential datasets for the European Commission's environmental monitoring needs.
