Yuri Gagarin was a Soviet pilot and cosmonaut. He became the first human to journey into outer space when his Vostok spacecraft completed one orbit of the Earth on 12 April 1961. Today Rosatom is working to create a new generation of megawatt-class nuclear reactors, so-called “thermonuclear batteries” for space missions - small volume, big capacity and one-time loading. Now nuclear fuel needs to be reloaded every 1.5-2 years. We are solving the task of doing this every 4-5 years and eventually every 25 years.
