When you’re floating hundreds of miles above Earth, reliable power isn’t just convenient—it’s essential. That’s why the Zero-g Battery Testing experiment aboard the International Space Station was so important.
Led by Glenn Johnson at NASA’s Johnson Space Center, this experiment took place during Expeditions 55/56 and 57/58. It aimed to test the performance and reliability of next-generation battery technologies in microgravity conditions.
In space, everything changes—including how batteries behave. Fluids inside batteries move differently, and heat dissipates in unusual ways. Engineers needed to know how these factors affect power storage and delivery.
The Zero-g Battery Testing setup involved deploying prototype batteries in a controlled environment on the ISS. These were monitored for voltage, temperature, and cycling efficiency. Researchers evaluated how spaceflight impacted charging and discharging patterns, degradation rates, and energy capacity.
The data helped NASA understand which battery chemistries are best suited for future missions—to the Moon, Mars, or for long-duration space habitats. Better batteries mean safer, longer, and more efficient missions.
The experiment also informs battery design on Earth. Technologies refined in space can lead to improvements in electric vehicles, renewable energy storage, and emergency power systems.
In a world increasingly reliant on portable power, learning how batteries perform in space teaches us how to make them better everywhere. From powering rovers on Mars to keeping your smartphone running longer, it all starts with tests like this one.
