NASA Johnson Space Center is seeking research-informed recommendations for measuring astronauts’ core temperature and thermoregulatory responses across spaceflight phases.
- **Government buyer:** National Aeronautics and Space Administration (NASA), Human Research Program (HRP), Johnson Space Center (JSC).
- **OEMs and vendors:** No manufacturers, OEMs, or vendors are named in the RFI; no specific products are requested.
- **Requested information:**
  - Recommend validated methods to measure and characterize core temperature and thermoregulatory responses before, during, and after spaceflight.
  - Address rest, routine operations, exercise, and re-entry or landing, including the rationale and methodology for recommendations.
  - Consider technologies usable in low Earth orbit, technologies in development for lunar and Mars missions, and retrospective analysis of NASA Life Sciences Data Portal datasets.
  - If applicable, recommend future studies for short- and long-duration low-Earth-orbit missions; relevant analogs may include patient populations, parabolic flight, and suborbital flight.
- **Products and quantities:** None specified; this is a request for information, not a defined product purchase.
- **Performance period:** No contract period of performance is specified. The research context includes International Space Station operations through station completion.
