Its two TV cameras are positioned radially opposite each other so that with each half-turn of the wheel, either camera faces toward the earth. Built by RCA's Astro-Electronics Division the TIROS wheel observes the entire earth and its cloud cover once a day. Abraham Schnapf, RCA's TIROS project manager, shows the spacecraft in its wheel position.en-USMeteorological satellitesWeather satellitesImage
