Vega

A new satellite to monitor crops, pollution and the growth of cities blasted off Monday from a tropical spaceport in French Guiana, adding another piece to Europe’s multibillion-dollar fleet of spacecraft tasked to track Earth’s ever-changing environment.

The first in a planned multi-decade series of European land imaging satellites is fastened on top of a solid-fueled Vega launcher at a French Guiana space base for liftoff Monday, kicking off a mission to track everything from global crop growth to urban sprawl.
