A combined team of undergraduates at Northwestern University and University of Illinois Urbana-Champaign are working together to build a satellite and instruments to test the fabrication of building materials in space.
The NASA mission is due to launch into orbit in the summer of 2018. It has two parts: a box-like satellite called a CubeSat (UIUC’s job) and a payload of instruments (NU’s job at the SpaceICE lab) to test freeze-casting . The instrumentation will freeze suspensions and study the corrugated structures of materials left behind in the freezing and thawing process. The undergraduate-only collaboration will determine if freeze-casting could be a viable mechanism for fabricating many different materials, from fuel cells to cocoa tablets, both on Earth and eventually on other planets.
The work is complex, rigorous and constantly evolving, especially because, as students graduate, they need to be replaced and re-trained from the ground up. Each university team not only has to design and test their own product, but also make sure that CubeSat and the SpaceICE payload work together.
Below are some photos that attempt to chronicle the day-to-day tasks of both teams, at NU and UIUC, where the satellite makers need to configure their spacecraft for the instrumentation.
