|This is the first time we have visited the Power Deck aboard the Polaris. Normally, the Power Deck is Astro's post, as he is specializing in studies to qualify him as a Power Deck officer, while Tom is specializing in Control Deck command, and Roger is a Radar Bridge expert. Although each cadet had his own specialized area of expertise and assignment, they were also cross-trained to allow each cadet proficiency in all areas of spaceship operation.
Here, Tom fills in for Astro, who is probably off-ship on a special assignment.
Like the previous photo, this one has been attractively but inaccuarately colorized.
