Universities Space Research Association Explores Atomic Space Batteries for Spacecraft

What's Happening?

The latest episode of 'This Week In Space' podcast features Dr. Robert O'Brien, director of the Center for Space Nuclear Research at the Universities Space Research Association, discussing the use of radioisotope thermoelectric generators (RTGs) to power spacecraft. RTGs have been crucial for NASA missions, providing long-term power in the outer solar system where solar panels are inefficient. These generators convert heat from nuclear elements like Plutonium and Americium into electricity, supporting missions from Apollo to Voyager. The podcast delves into the history and future of RTGs in space exploration.

Why It's Important?

RTGs are vital for deep space missions, where solar energy is insufficient. Their ability to provide continuous power for decades makes them indispensable for long-term scientific exploration. This technology supports critical missions, enabling data collection and communication far from Earth. As space exploration expands, RTGs will play a key role in powering spacecraft, potentially influencing future missions to Mars and beyond. The discussion highlights ongoing advancements in space nuclear research, which could lead to more efficient and sustainable exploration technologies.
