HuskySat-1 (HS-1)

Washington's First Student-Made CubeSat

Mission Overview

The HuskySat-1 (HS-1) is a 3U CubeSat designed, built, and tested by the Husky Satellite Lab. HS-1's goal was to test two experimental payloads, a pulsed plasma thruster (PPT), and a high-frequency K-band communication system, as well as hosting an Amateur Radio Linear Transponder.

HS-1 was developed by an interdisciplinary team at the University of Washington. It was aboard NASA's Cygnus NG-12 when it launched on November 2, 2019, and was deployed into Low Earth Orbit on January 31, 2020 to become the first amateur, student-built satellite from Washington state.

This CubeSat will demonstrate the capabilities of new technologies being developed at the University of Washington and expand the capabilities of CubeSats as a whole. In particular, the PPT and high-gain communications system will form the core technology suite on board the satellite. The HS-1 will also be flying a newly developed amateur radio linear transponder developed by AMSAT, which will contribute to the worldwide communication networks built and operated by ham radio enthusiasts.
