Russian science and Space exploration

During the Soviet era, the Soviet space program was highly renowned and accomplished many impressive results such as the first human in space (Yuri Gagarin) in 1961 and the first successful moon landing of an unmanned spacecraft (Luna 9) in 1966. After the breakup of the Soviet Union, Russia and the Ukraine continued its space program. Apart from the space program, experiments such as Ivan Pavlov's work on conditioned reflexes (known as Pavlov's dogs) became famous worldwide, and the legacy of experiments and results from former scientific and technological world leader Soviet Union is still living on.
