COLORADO SPRINGS — Swedish Space Corporation (SSC) believes it has an answer to the problem of how to deorbit spent cubesats before they can smash into more valuable spacecraft. SSC’s NanoSpace unit has developed miniaturized spacecraft thrusters using Micro Electro Mechanical Systems (MEMS) fabrication technology. The tiny thruster systems have been partially validated in space, on the company’s Prisma satellites that also proved out the nonhypergolic green propellant developed by another SSC subsidiary.
