AS101 Study Guide - Final Guide: Venera 10, Venera 11, Venera 9
Document Summary
In 1962 the spacecraft mariner 2 detected no magnetic field and subsequent missions to venus have confirmed this finding. This is likely because of venus" slow rotation resulting in little or no dynamo action. Thus, there is no protection from solar wind which generates a thick, upper ionosphere so no high-energy particles ever get to the surface of the planet. Exploration: there have been many failed attempts to explore our closest neighbour and a few successful ones. Venus was by sputnik 7 (feb. , 1961) by the ussr that ended when the final rocket stage failed to ignite. One week later venera 10 accomplished the same feat. It orbited venus, actively sending data back to. Earth for study, from mid-2006 until late-2014 when permanent contact with the spacecraft was lost. Earth - third rock from the sun - our. Home - lush, green and full of life. Studying earth seems like such a simple, perhaps even useless, thing to do.
