You are right, I should have explained what the article was about rather than snipping a quotation.
Here are my thoughts. Why didn't NASA have the foresight to have the rovers build (or have a pre-assembled) a small greenhouse with UV radiation
protection as well as temperature controlled? There should have been a way for a rover to maintain the greenhouse, take observations as well as plant
some seeds. This would have been an absolutely crucial experiment if terra forming is ever planned.
Plants = Oxygen production which = Atmospheric pressure which = Ozone layer
Plants breathe CO2 which comprises 90% of the Mars atmosphere.
