Agnirva Space Premier League - Expedition #31754: Neutron-1: A Hawaiian Satellite’s Space Journey to Track Neutrons

The Neutron-1 mission is an exciting small satellite project that made waves in the space community by combining cutting-edge neutron detection with educational outreach. Launched and operated by the Hawaii Space Flight Laboratory, Neutron-1 took to the stars during Expedition 63 aboard the International Space Station.

This CubeSat, no bigger than a loaf of bread, was designed to detect fast neutrons in low Earth orbit. Why neutrons? Because these high-energy particles provide critical information about space radiation environments. Understanding neutron flux in space helps scientists improve radiation shielding for astronauts and even advance technologies like nuclear propulsion.

The compact satellite was a technological achievement. Built by students and faculty from the University of Hawaiʻi at Mānoa, it carried a neutron spectrometer to monitor radiation levels as it orbited Earth. This data is essential for future long-duration missions to the Moon and Mars, where space radiation becomes a serious concern.

Another remarkable aspect of Neutron-1 is its role as a training ground for future aerospace professionals. Students participated in every phase of the mission—from design and assembly to testing and operations. This hands-on experience provided invaluable skills and encouraged STEM education across Hawaii.

In addition to neutron detection, Neutron-1 demonstrated several key spaceflight technologies. These included miniaturized onboard computing systems, advanced communications protocols, and innovative power management—crucial components for the next generation of space missions.

The data gathered from Neutron-1 supports NASA’s goals in developing deep space exploration tools while also contributing to scientific knowledge on neutron behavior and space weather. As more nations and companies venture into orbit, missions like Neutron-1 serve as essential stepping stones toward safer and more efficient spaceflight.
