SwRI developed the CoDICE instrument for IMAP with a unique thermal management design to address extreme temperature variations ranging from the intense heat of direct sunlight to the frigid cold of deep space. To maintain operational reliability and longevity, the half of CoDICE that will always face the Sun has a shiny “gold” surface to deflect heat energy, while the opposite side has a matte black surface to absorb as much heat as possible.
