Commander Corey and Cadet Happy are on the planet mercury organizing a rescue mission for Professor Mallison, who’s spaceship vanished on the dark side of Mercury, but a second emergency on the hot side of the planet sends the Commander Corey and his Cadet racing to the hot side of the planet, to Solaria, the City of the Sun in this episode originally broadcast on November 8th, 1952.
This episode manages to be genuinely tense and atmospheric in a way that many other Space Patrol episodes can’t achieve. It achieves this, in part, by cutting back and forth between Corey/Happy and two criminals, there’s a real cat-and-mouse feel to it, and it’s a lot of fun.
This is one of the first episodes of Space Patrol I ever heard, and it got me hooked on the series. As far as I’m concerned, this is an absolute high point.
