Radiation is all around us. From the rays of the sun to the electromagnetic waves that make your Wi-Fi and smartphones work, invisible forces are constantly flowing through our world. But what happens to these forces when you leave the Earth behind and travel into space? This question intrigued students from Valley Christian High School in San Jose, California, who conducted a fascinating experiment aboard the International Space Station (ISS).
In their project, "NanoRacks-Valley Christian High School-Observing Background Radiation and Magnetic Fields in Microgravity," these high school researchers teamed up with the Lowell Center for Space Science and Technology to explore the behavior of cosmic background radiation and magnetic fields in the microgravity environment of space.
Understanding the Basics: What is Background Radiation?
Background radiation is the low-level radiation present in the environment at all times. It comes from natural sources like cosmic rays from space, the Earth’s crust, and even elements in our bodies. On Earth, our atmosphere shields us from the full intensity of this radiation, but in space, astronauts are exposed to much higher levels. This makes it essential to understand how background radiation behaves in microgravity to better protect future space travelers.
The Role of Magnetic Fields in Space
Magnetic fields are another invisible force that plays a big role in our lives. Earth’s magnetic field shields us from harmful solar and cosmic radiation. But in space, especially aboard the ISS, the environment is quite different. Magnetic fields can be generated by equipment or may behave differently due to the lack of gravity. By studying how these fields change in microgravity, scientists can learn how to design better instruments and shielding for space missions.
The Experiment: Designed by Students, Flown to Space
This experiment was developed under the NanoRacks program, which allows student experiments to be flown to the ISS. The students built sensors to measure both background radiation and magnetic fields over time. The data was then transmitted back to Earth for analysis.
The sensors had to be small, lightweight, and durable to survive the launch and function in space. They were programmed to record data continuously, capturing changes as the ISS orbited the Earth. This provided a unique perspective on how radiation and magnetic fields vary at different altitudes and in different parts of Earth’s orbit.
What the Students Learned
The data collected helped students understand how background radiation levels fluctuate in space and how magnetic fields can be detected and analyzed in a microgravity environment. They observed changes in radiation levels depending on the ISS’s position, confirming theories about the influence of Earth’s magnetosphere and solar activity.
This hands-on experience gave students a taste of real scientific research. It also helped them learn how to formulate hypotheses, build and test hardware, analyze data, and draw meaningful conclusions—all crucial skills for future scientists and engineers.
Why This Matters
Understanding radiation and magnetic fields in space is not just an academic exercise. It has practical implications for astronaut safety, satellite design, and future missions to the Moon, Mars, and beyond. By engaging in such experiments, students are contributing to our collective knowledge and helping pave the way for humanity’s future in space.
This project is a powerful example of how educational partnerships can create opportunities for young scientists to participate in meaningful space research. It shows that with the right support, students can make real contributions to science and inspire others to explore the universe.
