A European environmental satellite rode a solid-fueled Vega launcher from a tropical spaceport at the edge of the Amazon jungle into polar orbit Monday night, adding a new eye in the sky to check on the health of crops and forests from space.

Europe’s fifth Sentinel Earth observation satellite will ride a four-stage Vega rocket into polar orbit 488 miles above Earth to begin tracking changes in agriculture and forestry patterns and monitoring natural disasters.

Ground crews have mounted the fully-fueled Sentinel 2B spacecraft, the next mission in Europe’s multibillion-dollar Copernicus Earth observation satellite fleet, on top of a Vega rocket inside a protective gantry on its launch pad in French Guiana for blastoff next month.
