What is the purpose of the Sentinel-2 mission?

Sentinel-2 is an Earth observation mission developed by the European Space Agency (ESA) to provide multispectral imagery. As part of the Copernicus Programme, it monitors land surfaces, tracking things like vegetation health, forest cover, and urban growth.

How many Sentinel-2 satellites are currently in orbit?

The mission consists of two identical satellites in a sun-synchronous orbit: Sentinel-2A and Sentinel-2B. Sentinel-2A was launched in 2015, followed closely by Sentinel-2B in 2017.

What kind of camera does the Sentinel-2 satellite use?

The satellites are equipped with a multispectral instrument (MSI) that captures optical imagery across 13 distinct spectral bands. These bands range from visible light to shortwave infrared, allowing scientists to see incredibly precise changes in the Earth's surface.

How often do Sentinel-2 satellites capture images of the same location?

With both satellites operating together, they provide a global revisit time of every five days at the equator. This high temporal resolution ensures that environmental changes, like crop growth or flood waters, are recorded rapidly.

description Sentinel-2 Overview

Sentinel-2 is an Earth observation mission developed by the European Space Agency (ESA) as part of the Copernicus Programme. Consisting of two identical satellites (Sentinel-2A launched in 2015 and Sentinel-2B in 2017), the mission provides multispectral imagery with 13 spectral bands at spatial resolutions of 10, 20, and 60 meters. The satellites orbit in a sun-synchronous pattern with a combined revisit time of five days at the equator, delivering data used for land surface monitoring, vegetation assessment, and water quality applications.
