Thanks again to the input from Jan Merlin, and another wonderful colorization job by Tom Powers, we now know what the "space fatigues" actually looked like. They were a slate blue in color, a bit lighter than the dress uniforms. The cadets usually wore these coveralls during space missions aboard the Polaris.
Tom Corbett (Frankie Thomas) looks on with apprehension as Captain Strong (Ed Bryce) communicates the current predicament to Solar Guard headquarters using the ship's transceiver. Roger Manning (Jan Merlin) is standing in the background of the control deck.
