CELSIUS has application to NASA as an insulation solution for the exposed Hydrogen tank barrel section on the SLS Exploration Upper Stage (EUS). CELSIUS can, for minimal mass provide ascent-to-orbit protection for the barrel section and excellent long term thermal and MMOD protection. CELSIUS will greatly extend the EUS on-orbit life providing NASA improved mission flexibility for Exploration Missions. CELSIUS also has future application for orbital propellant depots, habitats, and as a complete launch fairing solution. In this role, CELSIUS may be an enabling technology that provides a single solution to the ground-to-orbit and long term on-orbit storage of cryogenic propellants. With CELSIUS there is never a moment when the cryogenic system is unprotected, nor is transfer needed. The CELSIUS fairing and insulation system is carried directly to orbit and remains to protect the cryogen system from the duration of its useful life. CELSIUS is being investigated for ground applications for improved cryogenic insulation. This is a particularly large cost for NASA, the United States Air Force, and commercial launch providers who must maintain facilities and produce or deliver cryogenic propellants in large quantities in some of the warmest and most humid regions of the country. CELSIUS has significant interest from commercial launch providers where it can improvements cryogenic upper stage thermal and MMOD protection for minimal mass. This enables on-orbit services and mission flexibility in GEO, and planetary missions. It will also allow commercial providers to contemplate on-orbit upper-stage refueling and depot concepts for far greater mission capability that currently available. CELSIUS, as a complete inflated launch shroud or booster nose-cone would save hundreds of kilograms vs traditional systems.
