Study the latitude and time dependencies of the neutron spectrum to improve space weather models.


Study the latitude and time dependencies of the neutron spectrum in low-Earth orbit for the first time to improve current space weather models and mitigate threats to space and airborne assets. The data acquired from the INCA mission will help to expand space weather models and contribute to further understanding of the radiation belts.

Carrying a scintillator - silicon photomultiplier-based neutron detector. focus on albedo neutrons; however, the instrumentation will also be sensitive to solar neutrons. Albedo neutrons, produced via interaction of high-energy cosmic rays and solar particles with molecules in the upper atmosphere, represent a hazard for spacecraft as they can pass through most shielding, and can cause single event effects (SEE’s) in electronics. Since neutron flux is believed to be dependent on latitude and solar activity, the use of current models presents a risk for spacecraft in LEO.
