We are a team of undergraduate engineering students at Cornell University interested in spacecraft research. Specifically, we are exploring the field of magnetic flux pinning, and its applications to spacecraft docking, manipulation, and in-orbit assembly.
Flux pinning is a physical phenomenon that occurs when a magnetic field interacts with certain kinds of superconductors, causing the magnetic flux lines to be pinned inside the superconductor. When the superconductor is cooled below its material-dependant critical temperature in the presence of a magnet (a process known as field-cooling), the superconductor will effectively bind with the magnet. The flux-pinning interaction will create an equilibrium position for the magnet at its field-cooling position and exert a force to keep it at this location. This effect requires no external power besides that required to keep the superconductor cool, yet has a very high stiffness and damping. This interaction is ideal for use in sp
