Thermosphere gas and the ionospheric plasma. The International Space Station orbits the Earth within the middle of the thermosphere, between . It is convenient to separate the atmospheric regions according to the two temperature minima at about 12 km altitude (the tropopause) and at about 85 km (the mesopause) (Figure 1). The thermosphere (or the upper atmosphere) is the height region above 85 km, while the region between the tropopause and the mesopause is the middle atmosphere (stratosphere and mesosphere) where absorption of solar UV radiation generates the temperature maximum near 45 km altitude and causes the ozone layer.

Captain Video: Master of the Stratosphere group of crime-fighters known as the Video Rangers. He faces an interplanetary menace, as the evil dictator of the planet Atoma, Vultura (Gene Roth) and his lackey, the traitorous earth scientist Dr. Tobor (George Eldredge) are planning to conquer the earth. "Captain Video: Master of the Stratosphere" was the only serial adapted from television. It was one of Katzman's first forays into science fiction and was soon followed by "The Lost Planet. As produced by Sam Katzman, the serial had a production budget much larger than the famously small budget of the DuMont Television Network's live daily teleseries. The "Captain
