  The Lee Company's IEP Valve plays a crucial role in the propulsion system of Stellar Exploration, which is mounted on NASA's CAPSTONE CubeSat. NASA's Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) is a 55-pound spacecraft that will be launched in late 2021, taking three months to reach its destination and then orbiting the Moon for an additional six months. The primary objective of CAPSTONE is to test and validate the calculated orbital stability of the Near Rectilinear Halo Orbit (NRHO) around the Moon. This will help mitigate risks for future spacecraft and NASA's planned Gateway lunar outpost, a small space station that will orbit the Moon and provide astronauts access to the lunar surface.

  The IEP Valve and relief valve from The Lee Company are used in the propulsion subsystem of "Seeker," a 3U class CubeSat developed by NASA. The propulsion subsystem achieves six degrees of freedom attitude control using cryogenic gaseous nitrogen and twelve 0.1N thrusters within an approximately 1.25U form factor. "Seeker" was developed to demonstrate inspection capabilities for a half-autonomous manned spacecraft for one hour at a very low cost, contributing to the safety of future manned spacecraft operations. It was launched during the Cygnus NG-11 mission. Reference: https://ntrs.nasa.gov/citations/20190000668

  Three types of products from The Lee Company are used in the propulsion system of EOI Space, which is deploying 60 small observation satellites into a very low Earth orbit (VLEO) at an altitude of 250 km and providing satellite imagery services with a resolution of 15 cm. 1. Environmentally Resistant High-Speed Solenoid Valve: IEP Series Ideal for applications in Small Sat and CubeSat propulsion, functioning either as a fuel metering device for thrusters or gas supply systems. 2. Multi-Orifice: 43 Series 3. Multi-Orifice: Lee JEVA Helps provide tighter tolerances and accurate flow targets. The multi-orifice design reduces the risk of clogging. Comment from EOI Space CEO: Mr. Christopher The Lee Company is not just a supplier, but a strategic partner.
