Vega 2 spacecraft


The first pictures of the nucleus of Comet Halley were returned from the CCD TV system (TVS) placed onboard the two Soviet spacecraft Vega 1 and 2. Comet Halley was observed from 4 to 11 Mar. 1986, and ∼1500 images were transmitted to the earth. The raw data are given in digital numbers which must be converted into units of brightness. After a brief description of the experiment, the on ... Over the years, NASA and other space agencies have targeted asteroids and comets in their spacecraft missions. Some missions were designed specifically to learn more about physical characteristics of asteroids and comets while others were able to view asteroids on their way to other planetary destinations (such as JPL's Galileo mission). However by 2011, Venera-Glob has emerged as an independent concept, envisioning the launch of a multi-component mission as early as 2021. Venera-Glob's funding and development was not expected to start until the whole new revision of the Russian space program was to be approved by the Russian government for the 2016-2025 period. Phobos 1 and 2 were of a new spacecraft design, succeeding the type used in the Venera planetary missions of 1975-1985, last used during the Vega 1 and Vega 2 missions to comet Halley. Phobos 1 was launched on July 7, 1988 and Phobos 2 on July 12, 1988, each aboard a Proton-K rocket. Vega 2 is a Soviet space probe part of the Vega program. The spacecraft was a development of the earlier Venera craft. The name VeGa combines the first two letters Russian words for Venus and Halley They were designed by Babakin Vega 5VK Russian Venus probe. The Vega 5VK spacecraft was designed for a mission combining a flyby of the planet Venus followed by an encounter with Halley's Comet.
