Potatoes can grow on Mars?
No they can't!
Let's be clear:
Potatoes can grow in an experiment that simulated Martian conditions.Problem is, is that you have to have men on Mars to plant the Potatoes - and that's not gonna happen.
Here read the fantasy of some:
The International Potato Center (CIP) launched a series of experiments to discover if potatoes can grow under Mars atmospheric conditions and thereby prove they are also able to grow in extreme climates on Earth. This Phase Two effort of CIP's proof of concept experiment to grow potatoes in simulated Martian conditions began on February 14, 2016 when a tuber was planted in a specially constructed CubeSat contained environment built by engineers from University of Engineering and Technology (UTEC) in Lima based upon designs and advice provided by the National Aeronautics and Space Administration in Ames Research Center (NASA ARC), California. Preliminary results are positive. Source>>>>>>>>The Blessed Trinity will not allow men on Mars.
