ARCSTONE Space Flight Hyperspectral Instrument

By Mike Stebbins, COO - February 22, 2024

In early January 2024, Resonon delivered the ARCSTONE space-flight instrument to NASA Langley Research Center (LaRC). The ARCSTONE instrument was designed and built at Resonon and will be calibrated and then integrated into a 6U CubeSat (from Blue Canyon Technologies). The instrument is currently scheduled for launch into Low Earth Orbit in Q2 2025.

The ARCSTONE hyperspectral instrument will ultimately provide a new lunar calibration standard to be used by Earth-viewing satellite instruments.

The ARCSTONE Mission

By precisely measuring the lunar reflectance from Low Earth Orbit, ARCSTONE will enable the Moon to become a more accurate calibration source for Earth-viewing satellite instruments. The ARCSTONE instrument will improve the spectral calibration of the Moon by a factor greater than 10. This will lead to improved understanding of complex terrestrial systems, such as weather and climate change, while also reducing the cost and complexity of future Earth-viewing satellite instruments.

Instead of future missions needing to bring calibration sources along in the satellite, to achieve high-accuracy calibration, future Earth-viewing satellites will be able to take images of the Moon and use the data from ARCSTONE to calibrate their instruments. This will reduce costs and improve accuracy for future imaging satellite programs.

The ARCSTONE instrument was selected by NASA’s Earth Science and Technology Office (ESTO) for their In-Space Validation of Earth Science Technologies (InVEST) program. The ARCSTONE Principal Investigator is Dr. Constantine Lukashin, NASA LaRC.

Resonon is collaborating on the project with NASA LaRC, Quartus Engineering, the Laboratory for Atmospheric and Space Physics (LASP), Blue Canyon Technologies, US Geological Survey (USGS), and NASA Goddard Space Flight Center.

ARCSTONE Project History

Two ground-test prototypes of the ARCSTONE instrument (shown below) were developed in collaboration with NASA.
