Russian authorities have revealed plans which could see them send monkeys to Mars.
After putting monkeys into orbit in 1983 the Soviets moved on to human astronauts – but now the apes could be making a return.
While space experts say while the aim is to get humans on Mars, the length of the flight and effects of cosmic rays is said to make it impossible to plan for at the moment.
As a result the Institute of Experimental Pathology and Therapy – which supplied apes for the programme in the 1980s – has revealed plans for a monkey Mars mission.
It is likely to start with a ground-based simulation capsule mission for 520 days… and about 1,500 bananas.
