This is one of our next projects. We'll be teaming up with a private company....
"NASA is interested in utilizing SmallSats/CubeSats (6U-12U, < 50kg CubeSats targeted) for cislunar, interplanetary
and/or deep space missions, including lunar exploration precursor missions and missions identified in recent Planetary Science Deep Space SmallSat Studies (PSDS3). To accomplish this, advances in chemical propulsion systems for these class of spacecraft are sought, to complete maneuvers such as attitude control, trans-orbit injection, orbit changes, and planetary intercept, with a minimum of transit time. Chemical propulsion systems considered here can include cold-gas, warm-gas, monopropellants and/or bi-propellant systems. These propulsion systems are preferentially envisioned as modular, add-on sub-systems to the larger SmallSat/CubeSat payloads, and would be
comprised of the sum components of tank(s), valve(s), pressurant, feed system, thrusters and/or controls. Proposers should place emphasis on full propulsion systems offering long life, reliability, and minimalistic use of spacecraft resources (power, energy, volume, and mass). The use of existing component technologies to build a propulsion system is encouraged to minimize overall development, however proposers are also cautioned that experience to date has shown component technologies for larger systems do not necessarily and easily scale down to CubeSat platforms. Since the focus is on complete propulsion systems, proposals will not be considered that focus purely on individual component development (e.g., new thruster designs or propellant formulations) without addressing how the innovative component solution supports improved mission outcomes and clearly identifies how the product will be incorporated into an overall propulsion system solution. Component solutions must clearly demonstrate a willing system infusion customer and/or mission for consideration. Proposals are sought that can deliver a propulsion system hardware prototype at or greater than Technology Readiness Level (TRL) 4 (breadboard validations within a laboratory environment) within Phase II resources."
