The team designed and built an iodine feed system which stores solid iodine for a minimum of five years, and sublimates solid iodine to deliver gaseous iodine at a rate of at least 3 mg/s within 10 minutes in a zero gravity setting. The team validated this proof of concept design through rigorous thermal and structural modeling, in addition to testing the proof of concept for corrosion, leak resistance, flow control, thermal management, and propellant management.
