Key Takeaways
- The European Space Agency has selected two new Scout missions: Hibidis and SOVA-S, focusing on ecological and atmospheric research.
- Hibidis will study biodiversity under forest canopies, while SOVA-S will investigate atmospheric gravity waves.
- These missions exemplify ESA’s commitment to agile, low-cost, and innovative space exploration.
ESA Expands Scout Missions with Hibidis and SOVA-S
The European Space Agency (ESA) is enhancing its fleet of Earth-observing missions by selecting two new satellites: Hibidis and SOVA-S. These missions were chosen from four competing proposals after a thorough 10-month evaluation process.
Hibidis, short for Hyperspectral Biodiversity Scout, aims to provide insights into biodiversity and ecosystem functionality beneath forest canopies. This satellite will utilize a hyperspectral imager to differentiate between forest canopies and understories by capturing data from three vantage points. The goal is to assess various Essential Biodiversity Variables crucial for monitoring terrestrial ecosystems. SITAEL, a company based in Italy, serves as the prime contractor for Hibidis and looks forward to generating invaluable data via their new Empyreum platform.
On the other hand, SOVA-S, which stands for Satellite Observation of Waves in the Atmosphere – Scout, is designed to study atmospheric gravity waves. These waves, occurring between altitudes of 80 km and 120 km, play a significant role in Earth’s climate dynamics. SOVA-S will equip a shortwave infrared imager to deliver near-global daily observations of gravity wave phenomena by measuring airglow, a faint atmospheric light produced by various chemical reactions. The data collected could enhance climate and space-weather models, thereby improving forecasting accuracy for extreme weather events and aiding GNSS positioning in aviation.
SOVA-S is being developed by OHB Czechspace, which celebrates this project as a major milestone for the Czech space sector. The collaboration highlights the project’s cross-border cooperation with partners in Germany, including the German Aerospace Center (DLR). This initiative signifies ESA’s potential to unite diverse expertise in ambitious space explorations.
ESA’s Earth Observation Programme Board has officially approved the selection of these two missions. Simonetta Cheli, Director of ESA’s Earth Observation Programmes, expressed that inexpensive and expedited mission development does not compromise the quality of groundbreaking Earth science. The Scout missions demonstrate how innovation and quick decision-making can lead to impactful scientific advancements.
Hibidis and SOVA-S join existing Scout missions, including HydroGNSS, which was launched to measure critical hydrological climate variables, and NanoMagSat, aimed at studying the dynamics of Earth’s magnetic field. Also, the Tango mission focuses on measuring emissions of key greenhouse gases from industrial sources.
With the addition of Hibidis and SOVA-S, ESA continues to promote a future-oriented approach to Earth observation, preparing for challenges in environmental monitoring and climate science. The ongoing development of such missions also highlights the agency’s commitment to fostering innovation and agile spacecraft that can respond quickly to emerging scientific needs.
