The final flight of Europe’s Vega rocket lifted off Wednesday night from French Guiana, carrying an important environmental monitoring satellite for the European Union’s flagship Copernicus program.
The 98-foot-tall (30-meter) Vega rocket took off at 9:50 pm EDT Wednesday (01:50 UTC Thursday) from the European-run spaceport in Kourou, French Guiana. The launcher headed 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 was 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.
Sentinel-2C will replace Sentinel-2A, which launched on a Vega rocket in 2015 and is nearing the end of its life. An identical satellite named Sentinel-2B has been in orbit since 2017 and will be replaced by Sentinel-2D in 2028.
About an hour after liftoff, the Vega rocket’s upper stage released Sentinel-2C into an on-target orbit. Then, Sentinel-2C radioed its status to ground controllers, confirming the satellite was healthy in space.
The spacecraft in Europe’s Sentinel-2 series are similar to the US government’s Landsat satellites, providing wide-angle optical views of crops, forests, and urban areas to track changes season to season and year to year. The European Commission—the European Union’s executive arm—shares all the Copernicus data free of charge to users worldwide.
The Vega launcher is powered by three solid-fueled rocket motors, firing one after the other, and a liquid-fueled upper stage called the AVUM (the Attitude Vernier Upper Module) that ignites its engine multiple times to place satellites into slightly different orbits. Vega can deliver up to 3,300 pounds (1,500 kilograms) of payload mass into a 435-mile-high (700-kilometer) orbit.
