A thermos, which is used aboard a spacecraft in order to maintain a constant temperature for a crystal oscillator, was environmentally tested in space simulators. This thermos is composed of three-fold aluminum containers, between which thermal insulation is applied. Measured thermal resistance between them showed reasonably consistent values with the calculated ones. However, the temperature of the inner container was seriously affected by contamination of residual gas molecule showing heavy drift and large cyclic variation. Thus the thermos for space use is recommended to be kept in pressurized vessel.
