The final flight of Europe’s Vega rocket is scheduled for liftoff Wednesday night from French Guiana, carrying an important environmental monitoring satellite for the European Union’s flagship Copernicus program.

The launch is set for 9:50 pm EDT Wednesday (01:50 UTC Thursday) from the European-run spaceport in Kourou, French Guiana. The 98-foot-tall (30-meter) Vega rocket will head north from the launch pad on the coast of South America, aiming for a polar orbit about 480 miles (775 kilometers) above the Earth.

The sole payload is Sentinel-2C, a remote sensing platform set to join Europe’s fleet of Copernicus environmental satellites. The multibillion-dollar Copernicus system is the world’s most comprehensive space-based Earth observation network, with satellites fitted with different kinds of instruments monitoring land surfaces, oceans, and the atmosphere.
