NASA's TRISH team (Translational Research Institute for Space Health) recently issued an RFP for a healthcare tech platform designed for monitoring spaceflight participant health metrics during space missions. TRISH is a virtual consortium focused on applied research to ensure astronaut health during space exploration.
As avid space enthusiasts, and NASA Space Camp alumni, we were eager to apply.
Medplum submitted a proposal. We were invited to present to the TRISH team in June!
We're now anxiously awaiting the results.
Adapting to Space Challenges
A notable challenge in the RFP was the solution's ability to operate in a low power environment. To address this:
Medplum on Raspberry Pi
We successfully set up the entire Medplum tech stack on a Raspberry Pi 4 (8gb edition). Due to Medplum's open source nature and its reliance only on widely-used open source dependencies, this transition was quite smooth. For those curious, here's the Raspberry Pi 4 model we used.
Raspberry Pi OS Selection
A necessary adjustment was using the 64-bit edition of the Raspberry Pi OS because 32-bit Postgres isn’t widely supported or available as a Debian package. Following that, the Medplum installation mirrored the process on any other Linux server, as detailed in our Ubuntu installation guide.
Monitoring Power Consumption
With everything up and running, it became pertinent to gauge the power consumption. Using the SURAIELEC Watt Meter, we observed that when Medplum operates idly, the power consumption hovers around 1-1.5 watts.
Once power constraints were addressed, we used the Medplum React components to assemble a mock dashboard showcasing health metrics of Artemis mission astronauts, monitoring vital signs and other crucial health parameters. We also included the spacecraft's intrinsic metrics, such as cabin temperature, pressure, oxygen levels, CO2 concentrations, and radiation readings.
This exercise provided a practical demonstration of Medplum’s adaptability and versatility, underscored by the strength of open source tools. We believe the exercise emphasizes Medplum's flexibility and readiness for diverse challenges.
