What is BOHR?
BOHR (Betavoltaic Orbital High-Reliability) is an experimental commercial satellite developed to demonstrate betavoltaic energy technology in space.
Unlike conventional satellites that depend primarily on solar panels, BOHR carries a NanoTritium battery , which converts energy released from the natural decay of tritium into electricity.
The mission is intended to validate whether this technology can provide a reliable, maintenance-free power source for future commercial spacecraft.
What is Betavoltaic Technology?
Betavoltaic technology is a type of nuclear battery that converts the energy released during the radioactive decay of tritium into electrical power.
Working Principle
Tritium undergoes radioactive decay. Beta particles are released. Semiconductor material captures these particles. Electrical current is generated. The battery continuously supplies low-power electricity for years.
Unlike a nuclear reactor, no chain reaction takes place.
NanoTritium Battery
The BOHR satellite uses Nano Tritium battery technology, developed by City Labs.
Features
Extremely long operational life.
Maintenance-free.
Compact and lightweight.
Resistant to harsh space environments.
Reliable continuous low-power output.
