ISS Science for Everyone

Science Objectives for Everyone
Thermal control is difficult in the vacuum environment of space, where temperatures can fluctuate several hundred degrees between sunlight and shade and where radiation is the only way to transfer heat. NanoRacks-Valley Christian Junior High School-High Temperature Dispersion in Microgravity (NanoRacks-VCJHS-High Temperature Dispersion in Microgravity) studies how heat dissipates in microgravity, and examines various methods of accelerating heat dissipation. Results benefit development of future cooling and thermal regulation systems for next-generation spacecraft.

Experiment Description

Research Overview

  • The NanoRacks-Valley Christian Junior High School-High Temperature Dispersion in Microgravity (NanoRacks-VCJHS-High Temperature Dispersion in Microgravity) experiment tests how heat dissipates in a microgravity environment, and various methods of accelerating heat dissipation.
  • This experiment uses resistors to heat up liquid crystal paper and then measures the temperature, by color change reflected on the paper, as recorded by an internal digital camera.
  • A fan is also included to circulate the air and check the speed of dissipation, by measuring color change on the paper.

Description
The NanoRacks-Valley Christian Junior High School-High Temperature Dispersion in Microgravity (NanoRacks-VCJHS-High Temperature Dispersion in Microgravity) experiment determines how heat dissipates in microgravity without the benefit of convection cooling. The experiment consists of resistors used to heat up liquid crystal paper. Temperature is measured by color change reflected on the paper as recorded by an internal digital camera. A fan is also included to circulate the air and check the speed of dissipation, by measuring color change on the paper.

Applications

Space Applications
There is no natural convection in the microgravity environment of the International Space Station, so fans are necessary to move heat and air around. This investigation uses resistors to heat up liquid crystal paper and measures temperatures according to the paper’s color change.

Earth Applications
Students from Valley Christian High School conceive, design, build and test the experiments, providing a unique educational opportunity. Students learn about thermodynamics and other science, technology, engineering and mathematics (STEM) concepts while developing a connection to the space program.

Operations

Operational Requirements and Protocols

Data collection within the experiment is automated; downlink is done via scheduled STELLA/NanoRacks command window intervals for the NanoRacks Platform. Payload is ambient and soft-stowed, but late loaded (approximately L-72 hr) and an early return.

Crew interaction is limited to transferring the NanoRacks Module from the launch vehicle to the International Space Station (ISS), installing the Module into a NanoRacks Platform, activating the NanoRacks Platform, data retrieval (as needed) during the mission, and destowing and returning the Module.
