Labels: text | screenshot OCR: VIKING 1 AND 2 LANDER EQUIPEMENT @ Radio contact with the Earth is ensured by a 147-centimeter parabolic antenna, oriented by the on-board computer. In a ten-minute, daily hook-up (310 MHz, UHF), the orbiter and the lander can exchange 10 million bits of information. The orbiter's scientific equipment, representing a load of 65 kilos, includes three kinds of instruments: Viking 2 - Two spherical optic cameras with a focal length of 475 millimeters, each equipped with a six-color filter disk. photo - A Mars Atmospheric Water Detector (MAWD), a spectrometer that captures the solar rays reflected by Mars. This device can measure the level of precipitable water on Mars with a precision of one micron. - A multi-channel radiometer, composed of four small telescopes equipped with seven infrared detectors, used to measure the temperature of the Martian atmosphere within one degree (between -57º and 130 ℃).
