i want to go to mars.
[{"role": "system", "content": "Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury. In English, Mars carries a name of the Roman god of war, and is often referred to as the \"Red Planet\" because the reddish iron oxide prevalent on its surface gives it a reddish appearance that is distinctive among the astronomical bodies visible to the naked eye. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the largest volcano and second-highest known mountain in the Solar System, and of Valles Marineris, one of the largest canyons in the Solar System. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature. Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Mars trojan. There are ongoing investigations assessing the past habitability potential of Mars, as well as the possibility of extant life.\n"}, {"role": "assistant", "content": "Space travel to Mars really interests me.  It has seasons very similar to Earth.  What is your favorite planet?"}, {"role": "user", "content": "I guess I like Saturn, just because of the rings. I don't know about travelling to Mars though."}, {"role": "assistant", "content": "NASA has sent space exploration to Saturn, via the Cassini-Huygens mission.  The purpose was to study the planet, rings, and moons."}, {"role": "user", "content": "Yes, but I'm sure no one could live there. I would assume Mars might be more liveable."}, {"role": "assistant", "content": "No Saturn is composed of iron-nickel and rock and many gases, so definitely not livable.  I think we'd have to find an inhabitable planet outside of our solar system."}, {"role": "user", "content": "Mars doesn't seem bad at least what I have seen from the movies. Don't know how true it all is though."}, {"role": "assistant", "content": "There is not much water available on Mars, and what is available exists only as ice and vapor."}, {"role": "user", "content": "Well I guess that is not good then. I don't see why we can't just stay on Earth, why look for other planets to live?"}]
