ESA’s Test Bed Telescope (TBT) project is laying the groundwork for a network of telescopes that will autonomously scan the sky every night for asteroids that could pose a risk to our planet.
The project consists of two identical telescopes: one located at ESA’s Cebreros ground station in Spain, shown here, and one at the European Southern Observatory’s (ESO) La Silla observatory in the Atacama desert in northern Chile.
