Scalar Atomic Magnetometer for CubeSats

We propose to develop a compact, rugged, and accurate scalar atomic magnetometer suitable for CubeSat missions. The sensor will provide temperature-insensitive measurements of magnetic field magnitude which can be used in conjunction with established fluxgate technology to provide richer information about magnetic fields to further solar and space physics science goals.

Accurate measurements of scalar magnetic fields in space are crucial for the advancement of understanding the sun's outer corona, the solar wind, and the trapped particles in Earth's and other planetary magnetic fields. Magnetic storms are of practical importance because they can cause disruption in our essential communication and navigation systems on Earth. Magnetic field measurements can also contribute to the understanding of the composition of atmospheres and oceans on the planets and their moons.

A compact, rugged and temperature-insensitive scalar atomic magnetometer can find applications outside of NASA in geophysical survey and navigation.

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
