The European Space Agency (ESA) has unveiled plans for two new Earth-observing missions, Hibidis and SOVA-S, set to launch in the coming years. These missions aim to deepen our understanding of the planet’s ecosystems and atmospheric dynamics, leveraging satellite technology to provide insights that often elude ground-based observations.
Mission Overview
Hibidis, formally known as the Hyper-spectral Biodiversity Scout, will focus on assessing ecosystem and biodiversity health, particularly in forested and jungle regions. This mission will utilize a unique approach by examining the understory spectrum from various angles to gather comprehensive data. Developed by Italy’s SITAEL, with contributions from Belgian partners Amos and Vito and the University of Zurich, Hibidis will be constructed on SITAEL’s new Empyreum small satellite platform and powered by the SPARK electric propulsion unit.
Atmospheric Insights with SOVA-S
The second mission, SOVA-S, stands for Satellite Observation of Waves in the Atmosphere. It aims to monitor gravity waves in the atmosphere using a shortwave infrared imager. These gravity wave clouds manifest as moving rows or ripples in the atmosphere and are distinct from gravitational waves produced by astronomical events. By capturing data on these atmospheric phenomena, SOVA-S will contribute to refining weather models and forecasts.
Scout Class Missions and Their Significance
Both Hibidis and SOVA-S are part of ESA’s Earth Observation FutureEO program, which seeks to develop rapid, cost-effective missions addressing specific scientific inquiries. The missions must be prepared for launch within three years of selection, adhering to a budget cap of 35 million Euro. Simonetta Cheli, ESA’s Earth Observation Program director, emphasized the importance of these missions in demonstrating that significant advancements in Earth science can be achieved without extensive budgets and prolonged development timelines.
These missions join a growing roster of ESA Scout Class missions, including HydroGNSS, which launched on November 28, 2022. Hibidis and SOVA-S are expected to launch from Vandenberg Space Force Base in California, entering a sun-synchronous orbit that is increasingly favored for Earth observation due to its consistent lighting conditions.
As Hibidis and SOVA-S prepare for their upcoming launches, they represent a significant step forward in our quest to understand the complexities of Earth’s ecosystems and atmospheric processes.
