Human mission to Mars takes two years and is extremely expensive. That cost is mainly to do with keeping the astronaut alive, healthy and sane, otherwise it will be pointless. I worked out that all the cost can be reduced to the cost of non-human mission if only find a way to hibernate or freeze the astronauts during that journey. This idea is not new and is used in sci-fi films such as Aliens and Interstellar. Scientists are already working on cryogenics but it has proved to be impossible so far.

I came across an untried method that might make it possible to achieve this and it is very cheap and practical. Watch this space . . .
