One way ticket

So the concept of going to Mars is an interesting one. You fly to Mars and you try and colonise it. Never mind the alien culture that hides underground surviving off the lush resources of water and fungus that grow in their caverns that are heated by air conditioners designed to cover square Kilometres of tunnels with heat.

It's okay though. It'll be over hyped within their culture when an alien space ship lands on the surface, spotted by Astrologists and conspiracy theorists who are renting a heated rock on the surface.

Then the Humans will do one of two things: They'll play it smart and make peaceful negotiations with Societies most Prestigious (Those closest to the heating device) or they'll use whatever weapons they have to shoot the Martians down, the same Martians who made Fungal Brownies and covered them in Glad wrap.

The Aliens will be confused and will simply try and shoot them down while the humans try and figure out a way to save humanity by destroying the heating core and having the Martians suffer in the cold... Or move out to a different region, since that's the backup plan for their species.

One thing is for certain: there is no stopping them; the ants will soon be here. And I for one welcome our new insect overlords. I’d like to remind them that as a trusted TV personality, I can be helpful in rounding up others to toil in their underground sugar caves
