Texas, USA – In a groundbreaking technological step that opens unprecedented horizons for space exploration, SpaceX launched the BOHR (Borehole High Reliability Betavoltaic) commercial satellite as part of its successful Transporter-17 mission. This makes it the first commercial satellite in history to operate in low Earth orbit using a nuclear power source.
Betavolta technology: A revolution in energy sustainability
The BOHR satellite features an advanced battery based on betavoltaic technology, an engineering innovation developed by the American company City Labs. This battery operates using the radioactive hydrogen isotope tritium, which emits beta particles when it decays. These particles are then directly converted into sustainable electrical energy.
Although the moon is equipped with conventional solar panels, the nuclear battery represents a crucial experimental model. The aim of this innovation is to demonstrate the technological capability to continue operating in environments devoid of sunlight. This represents a radical solution to the energy problem that has plagued spacecraft for decades.
From government missions to the commercial sector
CityLabs explained that relying on radioisotope-based energy sources is not a new concept; international space agencies, most notably NASA, have used them for years in their sensitive space missions. However, the real breakthrough today lies in transferring this technology from the realm of high-cost government missions to commercial projects. This paves the way for the privatization and expansion of advanced space technologies.
Future prospects: The conquest of the “lunar night”
The company aims to use this technology to expand lunar exploration, hoping to develop radioactive isotope-based power and heating sources for lunar probes and vehicles. This is crucial for future space operations, especially during the lunar night, which lasts for about two weeks. When exploring permanently shadowed lunar craters, sunlight never reaches them.
With this achievement, SpaceX and City Labs confirm that the future of space exploration will not be confined to solar orbits. Instead, it will extend to the darkest corners of the universe, thanks to the ability of spacecraft to operate completely independently of starlight. This opens a new chapter in the history of commercial space technology.
