Sentinel-2A

Sentinel-2A is equipped with a sophisticated Multispectral Instrument (MSI) that records data across 13 distinct spectral bands. These bands range from visible light to shortwave infrared, allowing scientists to analyze different features of the Earth's surface. This technology enables precise monitoring of land cover and vegetation health.

Sentinel-2A was successfully launched into space in June 2015 aboard a Vega rocket from Kourou, French Guiana. It was the very first optical Earth observation satellite launched as part of the European Space Agency's Copernicus program. It joined an extensive constellation of satellites designed to monitor the global environment.

The primary mission of Sentinel-2A is to monitor land surface changes, track agricultural practices, and map the health of global forests. Its multispectral imager provides high-resolution imagery that is vital for agricultural and forestry management. It is also heavily used to track the aftermath of natural disasters like floods and wildfires.

Sentinel-2A operates in a sun-synchronous orbit that allows it to revisit the exact same location on Earth every 10 days. When combined with its twin satellite, Sentinel-2B (launched in 2017), the revisit time is reduced to just 5 days. This frequent coverage allows scientists to track environmental changes almost in real time.
