A new technology developed by Dr. Michael Hecht at MIT has the potential to solve major challenges in balloon-based exploration of Venus. The MOXIE oxygen-generating system uses a solid oxide electrolysis process (SOE) that splits carbon dioxide into carbon monoxide and oxygen, making it possible for balloons to generate their own lift and stay aloft indefinitely.
The SOE system runs more efficiently during the day due to abundant solar power provided by Venus’ proximity to the Sun. Running the system in reverse at night could also generate electricity, eliminating the need for heavy batteries and ensuring round-the-clock operation.
Beyond balloons, the extracted carbon dioxide could serve as fuel for future Venusian aircraft, turning a floating platform into a potential refueling station for other missions. However, the system must maintain an 75% efficiency rate to avoid clogging with soot.
Dr. Hecht believes that this technology could not only revolutionize exploration of Venus but also be applied to other thick-atmosphere worlds like Titan, potentially paving the way for new discoveries in planetary science.
