These technologies enable a broad range of missions including but not limited to landers, ascent stages, in-space transfer vehicles, habitats, and in-situ resource utilization (ISRU) operations and encompasses both in-space or extraterrestrial destination surface environments.","exampleTechnologies":"Vacuum and partial vacuum insulation systems; low conductive heat-load structure; solar shields applications to limit insulation exposure; cryocoolers and integration for reduced/zero boil-off of propellants and provide liquefaction; micro-g fluid dynamics (2-phase transport, surface wetting, surface tension, evaporation/condensation); propellant acquisition/management devices (surface tension devices); instrumentation/mass gauging in micro-g conditions; pressurization and pressure control (passive/active) and propellant mixing/destratification; propellant systems/hardware chill-down; low leakage, multi-use isolation valves; propellant transfer for stages, ISRU, other applications; propellant slosh dynamics; liquefaction for ISRU and other applications; heat rejection (cryocoolers or thermodynamic vents, other systems); valves, actuators and components","hasChildren":false,"hasInteriorContent":true}],"description":"Two novel cryogenic couplings will be designed, fabricated and tested. Intended for in-space use at cryogenic propellant depots, the couplings are based on patented Venturi-Offset Technology (VOST) and will provide small fluid and heat leakage at high flows with a low pressure drop. Entirely mechanical, insertion opens the passage, removal closes the passage. Mating force and alignment requirements are small. With only eight major parts, reliability is high and mass is low. Redundant seals, integrated health measurements, and robotic control are possible.

The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
