Roscosmos has uploaded to its Facebook page a video showing the image of a nuclear-powered spacecraft of the future.

"The Keldysh Center is currently conducting research into spacecraft boasting more powerful engines - nuclear power plants of a new class. They do not need solar light or solar cell panels," the video says.

Earlier, Roscosmos unveiled plans for making a test sample of a megawatt class nuclear engine meant for flights into deep space.

In 1970-1988 the Soviet Union carried out the launch of 32 spacecraft with thermoelectric nuclear power plants. In 1960-1980 a nuclear rocket engine was developed and tested at the Semipalatinsk test site.
