The World’s First Commercial Nuclear Satellite Blasts Off Today!
Quick Summary
Early this morning, a SpaceX rocket launched a very special satellite into space. It is the first commercial satellite ever to run on nuclear power. This tiny spacecraft could change how we explore the Moon and beyond.
What Happened?
At 3:12 in the morning on July 7, a SpaceX Falcon 9 rocket lifted off from Vandenberg Space Force Base in California. It was carrying 81 different satellites on a mission called Transporter-17 — like a carpool for spacecraft!
One of those satellites was very different from the rest. It is called BOHR, which stands for Betavoltaic Orbital High-Reliability. It was built by a company called City Labs, based in Florida. BOHR is the first satellite ever built by a private company that gets its power from nuclear energy.
But don’t picture a giant nuclear reactor! BOHR uses a special tiny battery made from a safe material called tritium. Tritium releases very small, harmless particles as it slowly breaks down — like a super-slow, invisible sparkle. A special chip inside BOHR catches those particles and turns them into electricity.
Think of it like a glow-in-the-dark sticker. The sticker glows without any batteries or sunlight because of a tiny chemical reaction inside it. BOHR works the same way — just using nuclear particles instead of glowing chemicals.
The rocket’s booster landed safely on a drone ship in the Pacific Ocean after launch, marking its 11th successful flight.
Why Does It Matter?
Most satellites use solar panels to make electricity from sunlight. But solar panels stop working when a satellite flies into Earth’s shadow, hides in a dark crater on the Moon, or travels deep into space where sunlight is weak.
A nuclear battery keeps making power no matter what. That makes it perfect for missions to the Moon’s dark side, for exploring deep space, or for any place where the sun can’t reach.
City Labs hopes this mission will pave the way for future spacecraft that can stay powered up even in the darkest, coldest corners of the solar system. Scientists say the satellite is expected to orbit Earth for about 10 years, sending back data to help engineers learn how the nuclear battery performs.
Big Words
- Nuclear energy — energy that comes from tiny changes inside atoms, the incredibly small building blocks of everything
- Tritium — a safe, naturally occurring form of hydrogen that slowly releases tiny particles as it breaks down over time
- Betavoltaic — a way to make electricity by catching the tiny particles released by a radioactive material, similar to how a solar panel catches light
- Cubesat — a very small, boxy satellite, often about the size of a shoebox, used for experiments and technology tests
- Rideshare mission — when one rocket carries many different satellites at once, like carpooling to school
Fun Fact
Tritium, the material powering BOHR’s nuclear battery, is also what makes some glow-in-the-dark watch hands glow without ever needing new batteries — even after 20 years!
Think About It
If a nuclear battery can power a satellite for 10 years without sunlight, what other places — in space or on Earth — might benefit from this kind of energy?
