The energy transfer experiment explores energy transfer in space.  Three aluminum disks, one painted black, one painted white and one with a polished finish will be mounted in a window on the ISS and exposed to the Sun.  Temperature sensors, one buried within each disk, will be connected to the STFS data unit to track how the disks heat up as they absorb energy from the Sun, and in turn transfer the energy to the air inside the ISS.

What are the mechanisms for the energy transfer? How will the surface finish effect the energy transfer?

Which one will heat up the most when exposed to the sun?
