When would a Planetary Rover Freeze in the Moon Titan? To be more exact, in how much time will it freeze if we managed to send a Rover to Saturn's Moon Titan. More info on the Moon, Titan is a Moon of Saturn. It is very cold. -290 degrees FahrenheitTitan's gravity is 14% of Earth gravity. it's the only world besides Earth that has standing bodies of liquid, including rivers, lakes and seas, on its surface. Like Earth, Titan's atmosphere is primarily nitrogen, plus a small amount of methane. Some of the weather phenomena we'd be familiar with on Titan include dust storms and monsoonal rains.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
