Compare Titan to Rhea. Estimate the strength of surface gravity on Titan compared to the gravity on Titan. How does this affect the possibility of an atmosphere on each?
Use g=GM/R2
Titan Radius: 2,575 km, Mass: 2.31 x 1021 kg
Rhea Radius: 764 km, Mass: 1.35 x 1023 kg
Assuming all other variables were earth based besides atmospheric pressure, calculate the temperature at which water would boil at sea level on Titan versus Earth? And explain why using molecular concepts. Consider the pressure of Earth’s atmosphere at sea level to be 1 atm and the pressure of Titan’s atmosphere at sea level to be 1.45 atm.

How probable is it that other solar systems will have habitable planets, given what you know about the solar nebula theory? Take a look at NASA's Kepler mission and write a half-page summary of it.

- What is the evidence for a liquid water ocean on Europa, and why is this interesting to scientists searching for extraterrestrial life?arrow_forwardPresent theory suggests that giant planets cannot form without condensation of water ice, which becomes vapor at the high temperatures close to a star. So how can we explain the presence of jovian-sized exoplanets closer to their star than Mercury is to our Sun?arrow_forwardDoes Titan experience volcanism today? Impact cratering? How do you know?arrow_forward
- Given that no sunlight can penetrate Europa’s ice shell, what would be the type of energy that could make some form of europan life possible?arrow_forwardAt present, NASA is planning a mission to Europa, to try and assess its habitability. An argument might also be made for Enceladus, however. Let's imagine you had to pick one of those moons to send an uncrewed (i.e. robotic) mission to. The spacecraft will probably orbit the giant planet (Jupiter in the case of Europa, Saturn in the case of Enceladus), and make many flybys of the moon you're studying. Which moon would you pick, and why? The goal here is to briefly discuss the pros and cons of each moon as a target for a mission. You don't even have to have a strong preference either way, just lay out a few pros and cons for each.arrow_forwardInvestigate plans for future study of Europa’s ocean, either from Earth or with spacecraft. How might they help us learn whether Europa really has an ocean?arrow_forward

You don't even have to have a strong preference either way, just lay out a few pros and cons for each. Breaking this into a few short paragraphs will probably be a good ideaarrow_forwardMission to Titan: Titan is the largest of Saturn’s moons and the only moon in the Solar System that possesses a dense atmosphere and large liquid bodies (seas or lakes) at its surface. For these and other reasons, many exobiologists think that Titan is the most likely place in the Solar System beside Earth where life might exist. NASA is considering sending a 600 kg space probe into orbit around Titan in order to map its surface. This would be followed a few years later by a 320 kg robotic lander that would land on the surface of Titan in order to look for life. a) What would be the space probe’s velocity and orbital period if the probe were to orbit at an altitude of 70 km above the surface of Titan? b) What force would the lander’s thrusters need to produce in order to allow the lander to hover just above the surface of Titan.arrow_forwardDescribe the atmosphere of Titan.
