Russia released a stamp of 12 Roubles on 25 Jan 2011 on the 100th anniversary of birth of Mstislav Keldysh (1911-1978). He was a pioneer in the field of mathematics and mechanics, theoretical astronautics. As president of Academy of Sciences, he Played a crucial role in the development of computational mathematics and machine, in the creation of effective methods of calculation applied in nuclear and space technology.He was one of the initiators of the deployment works on space exploration and the creation of space rocket systems, leading to the mid 1950's. development of theoretical assumptions withdrawal of artificial bodies into Earth orbit, and in the future - Flight to the Moon and other planets of the solar system. Also directed the scientific and technical advice on the coordination of research institutes and design to create the first artificial Earth satellite. Made an enormous contribution to the manned flights, in the formulation of scientific problems and studies near-Earth space, the interplanetary medium, the Moon and other planets in the solution of many problems of space flight mechanics and control theory, navigation, and heat transfer.
