## SpaceX’s Historic Launch of the First Commercial Nuclear Satellite
SpaceX has made history with the successful launch of the first commercial nuclear satellite, known as BOHR. Developed by City Labs, this CubeSat represents a monumental step for the use of nuclear energy in space applications. It was launched as part of the Transporter-17 mission on July 7, propelled into orbit by a Falcon 9 rocket from SpaceX’s Vandenberg base. This venture signifies a shift in the paradigm, demonstrating that nuclear energy can power not only governmental projects but also commercial satellite missions.
### Tritium to Make History in Space
At the heart of BOHR’s innovative design is its use of tritium for energy production. The Betavoltaic Orbital High-Reliability (BOHR) CubeSat harnesses a nuclear reaction similar to that used in the Voyager probes. However, instead of plutonium, BOHR utilizes beta particles emitted during tritium decay. These particles can then be converted into electricity through semiconductor technology. The choice of tritium is particularly advantageous, as it produces significantly less radiation, making pre-launch handling safer and more manageable.
### Launch Details
The Transporter-17 mission encompassed a total of 81 payloads, with BOHR being one of the standout components. Within just 50 minutes post-launch, all payloads, including the nuclear satellite, were successfully placed into their designated orbits. This timeline emphasizes SpaceX’s efficiency and reliability in conducting complex orbital missions.
### Two Possible Uses of Nuclear Energy in Space
The application of nuclear energy in space has garnered attention for two key reasons. Firstly, it offers a viable energy source for spacecraft venturing far beyond the Sun’s reach—exactly why the Voyager probes relied on nuclear power. Secondly, nuclear energy proves beneficial in environments where solar energy is insufficient. For instance, the lunar south pole is often shrouded in darkness. Future Artemis missions could heavily rely on nuclear power to sustain operations in these shadowed regions.
### A Project With Robust Support
The BOHR project’s development received backing from the United States Department of Defense, reflecting its significance and potential. It is the first nuclear mission to obtain approval for launch from the Federal Aviation Administration under the Presidential National Security Memorandum 20. This governmental support indicates the high-stakes nature of the initiative, alongside its commercial aspirations, and highlights the collaborative spirit between private enterprises and public agencies.
### A Preliminary Test for Future Applications
While BOHR is currently in orbit and ready for test reactions, it still utilizes solar panels to maintain its operational energy needs. The mission’s primary objective is to validate the potential of tritium decay for nuclear energy production in space. Looking ahead, future iterations may develop satellites that rely solely on this decay process, pushing the boundaries of commercial space missions.
