What is a SmallSat?
The UMN Small Satellite (SmallSat) Research Lab (SSRL) works with a form of SmallSats called CubeSats. NASA defines a SmallSat as a spacecraft with a mass less than 180 kilograms, and a size less than that of a large kitchen fridge.
What is a CubeSat?
CubeSats are a type of SmallSat that use a standardized dimensional design of 10x10x10 centimeters, or “1U”. 1U CubeSats can be combined to gain dimensions of 2U, 3U, 6U and many more. To use imperial units, these cube units are roughly 4 inches long, and a little smaller than one quart.
Why CubeSats?
NASA has been using a CubeSat Launch Initiative (CSLI). This initiative allows SmallSats to piggyback off of planned rockets. This gives the SSRL the chance to complete our research. A mission statement is also required, as per the CSLI. The research must “address aspects of science, exploration, technology, development, education or operations”. NASA’s goal with this initiative is to assist in creating opportunities for students, faculty, and research projects, and to bring more STEM students to the United States. CSLI is one program which is funding SmallSats for STEM education purposes. University Nanosatellite Program (UNP), under the United States Air Force (USAF), is another program funding SmallSats. UNP is funding one of our current missions, EXACT. The USAF uses this program as an education incentive, and as a way to seek out innovative solutions to military related challenges.
