Its mission was to serve as a communications relay for the lander and to explore cloud layers and atmospheric parameters with several instruments and experiments: * 1.6-2.8 μm IR Spectrometer * 8-28 μm IR Radiometer * 352 nm UV Photometer * 2 Photopolarimeters (335-800 nm) * 300-800 nm Spectrometer * Lyman-α H/D Spectrometer * Bistatic Radar Mapping * CM, DM Radio Occultations * Triaxial Magnetometer * 345-380 nm UV Camera * 355-445 nm Camera * 6 Electrostatic Analyzers * 2 Modulation Ion Traps * Low-Energy Proton / Alpha detector * Low-Energy Electron detector * 3 Semiconductor Counters * 2 Gas-Discharge Counters * Cherenkov Detector The orbiter consisted of a cylinder with two solar panel wings and a high gain parabolic antenna attached to the curved surface. A bell-shaped unit holding propulsion systems was attached to the bottom of the cylinder, and mounted on top was a 2.4 meter sphere which held the landers. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Venera 10」の詳細全文を読む スポンサード リンク
