HawkSat-1 was a single-unit CubeSat which was built and is being operated by the Hawk Institute for Space Sciences (HISS), Pocomoke City, Maryland. It is based on a Pumpkin Inc. CubeSat kit, and carries a technology demonstration payload, primarily as a proof of concept mission, testing command, data and power subsystems, as well as solar panels and communications.

It carries a commercial material exposure research payload for an undisclosed "major aerospace company",{{cite web|url=http://www.nasa.gov/centers/wallops/pdf/326337main_Cubesat%20backgrounder.pdf|title=CubeSats|work=HawkSat-1|publisher=NASA|access-date=31 October 2021|archive-date=9 July 2009|archive-url=https://web.archive.org/web/20090709150539/http://www.nasa.gov/centers/wallops/pdf/326337main_Cubesat%20backgrounder.pdf|url-status=dead}} {{PD-notice}} which exposes a number of material samples to space, and records the effects of exposure on the materials. The data was to be sent to Earth by means of a storage and dump communication system.
