hi how are you? what do you know about mars?
gpt
I am well and know nothing about mars, other than it is the red planet. do you know a lot?
human
I do not know much. it is the fourth planet from the sun. it is named after the god of war.
gpt
I did read that it is called the red planet because of the reddish iron oxide on its surface.
human
Yeah, the sunsets are different there too. the atmosphere makes them blue. not much air on mars though.
gpt
*raises eyebrows* It has the impact craters of the moon and the valleys, deserts and ice caps of earth. How interesting!
human
It looks like a place we could live, but i think it would take some work. 
gpt
A lot with all of that thin air! I wonder if it is actually possible.
human
we would need atmosphere converters, plus some source of water, which might be there. the gravity would be lower and the year would be longer. 
gpt
Does that mean I would be lighter on Mars?
human
Yes, but your muscles would probably atrophy too.
gpt
*opens mouth slightly* That would be problematic. Sound shave a higher pitch on mars than they do on earth.
human
Yes, we would sound a bit silly on Mars. But that would make life there more bearable, i think. LOL
gpt
WOuld a colony is expectd on Mars by 2023.
human
I think that is a bit ambitious. traveling there is a huge headache. then you get there and what? is backup or relief coming soon? sounds far fetched.
gpt
*eyes widen* Can you imagine losing a satalite on Mars?
human
Yeah, that was a huge mistake. Feet vs. meters. Who uses feet any more? no one. no one uses that system.
gpt
Only the US and we are too stubburn to get rid of it.
human
yeah, but for engineering and science, it seems strange to me. Anyway, great chat!
gpt
*body relaxes* Ditto. Nice chatting with you!
human
Have a great day!
gpt
You too. Take care.
