ESA Adds Two Satellites to Scout Program

Why this is here: Hibidis will observe Earth’s surface from three different viewing angles, allowing scientists to distinguish dense forest canopies from the ecosystems below.

The European Space Agency selected Hibidis and SOVA-S, two new Earth observation satellites, to join its Scout program in Darmstadt, Germany. ESA’s Earth Observation Programme Board approved the missions after a ten-month evaluation. Hibidis will use hyperspectral imaging to study ecosystems under forest canopies, while SOVA-S will investigate gravity waves in the upper atmosphere.

These satellites represent ESA’s strategy for delivering scientific data quickly and affordably. The Scout program contrasts with traditional large-scale satellite projects, prioritizing agility and innovation. SITAEL, an Italian aerospace company, will serve as the primary contractor for the Hibidis mission.

Scientists acknowledge current climate models do not fully account for atmospheric gravity waves, a key focus of the SOVA-S mission. Understanding these waves could improve climate forecasting and space weather prediction. The program continues to expand, with HydroGNSS and Tango already in development, seeking to address critical environmental questions.
