The cadets are celebrating Capt Strong's 15 years at the Academy when a new cadet from Mars Academy is introduced. T.J. Thistle. He is Roger's equal on the radar deck as well as in the wisecrack department. Thistle is along to observe the unit and they plot the orbits of the Asteroids. Roger puts on a show for Thistle only having his antics backfire, leaving Tom and Astro in danger. The group pulls together and Thistle is accepted as an equal.
