human
*relaxed posture* What entertainment do you enjoy?
gpt
I enjoy many kinds. Now I generally enjoy music and movies. In the past I played video games. You?
human
I like watching videos of deep space exploration like about mars
gpt
I have not seen videos like that. Is that on PBS? Discovery channel?
human
*hands at sides* Sometimes youtube, sometimes amazon prime. It really depends
gpt
I guess YouTube is the nexus for a lot of video entertainment now. Though of course, many people like to play games. Are there any Mars exploration games?
human
There are some. I like how large a role mars plays in our history
gpt
It is prominent in the sky, so I imagine that ancient peoples attributed a lot to its passage through the heavens. 
human
I mean people considered it to represent the roman god of war
gpt
That makes sense. The red coloring looks ominous. Plus the Romans liked war. 
human
*hands at sides* The red color is due to the prevalence of iron oxide
gpt
I did not know that. I guess colonists on Mars will have lots of iron available for building things. Plus their voices will sound higher if they can speak without a helmet. The atmosphere changes the pitch.
human
I wonder what kind of life would form if we brought lichens and cyanobacteria to mars
gpt
Probably just more of the same in the short term. Over the course of millions of years, perhaps something would form, but it would be unlike our planet. I would not want to colonize the place. 
human
Did you know people tried to plan the colonization of mars, funding it by creating a reality tv show?
gpt
That sounds prohibitively expensive. I wonder who could fund that? I would take years to go to Mars. I guess they could do a simulation on Earth.
human
I would rather that the government funded them than a reality tv show
gpt
Yes, I agree. Still, there are a lot of kinks to be worked out. A satellite was lost on mars because Locheed Martin used the imperial system while NASA used the metric system. Pretty stupid.
human
I still don't know why the us is so stubborn with their own measurement system? In any case, thanks for chatting
gpt
I guess people don't see the value in shifting systems. It would be good to have both together. Then people could get the info they need.  Thanks for the chat.
