Temperatures on Mars in areas hit 30C, many of the unmodified lichen reproduce well below these temperatures. I don't see a point in 'planning' when we already have the necessary bacteria and fungus to be doing. Bacteria spores have survived millions of years, temperatures colder than anything on Mars, freeze drying and beyond, whilst still being viable when reanimated by the correct conditions. Find key locations and seed them. Craters and valleys will trap any heat produced by these lichen (via lower albedos and the bacteria themselves) making them ideal locations if their temperatures break freezing. Mars' strong winds will do all the work of spreading the spores into surrounding areas that are habitable, or that may become habitable if the lichens have adequate effect. I fail to see what the harm in trying is aside from a loss of money. However any space launch comes with the expectation that it could fail, any deployment comes with the expectation that it could fail. Failing is part of going to space. However the crucial here is that this produces valued data. Until we get data we are guessing and all the mythical genetically modified lichens in the world will do nothing if we guessed wrong and they'll be guessing blind for attempt 2. We should be doing a trial run with materials off the shelf, so to speak. If our off the shelf materials don't work, then we design our own. It should never be the other way around. I know, we're hackers, we like to tinker, but YC is about start ups, it's about doing. Not everyone here had 20 years to fiddle making their own programming languages to perfectly execute their start up, they just got on and did it with off-the-shelf stuff until they had to invent, if they had to.
