Courtesy of NASA's National Space Science Data Center . ... Venera 5 was launched from a Tyazheliy Sputnik (69-001C) towards Venus to obtain atmospheric data. The spacecraft was very similar to Venera 4, although it was of a stronger design. When the atmosphere of Venus was approached, a capsule weighing 405 kg and containing scientific instruments was jettisoned from the main spacecraft. During satellite descent towards the surface of Venus, a parachute opened to slow the rate of descent. ...

Welcome to VDP home page. ... Operation and Measurements The VDP instrument was designed for determination of integral flux vector or integral energetic spectrum at the range 0.2 - 2.4 keV of ions or electrons of magnetospheric plasma. The instrument includes 6 identical Faraday caps, located by following ways: . ... In case of constant voltage, sensor supplies the total flux of ions plus flux of electrons above 2400 eV energy, or total flux of electrons plus flux of ions above 2400 eV energy. ...
