Mission 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.
Planetary scientists are excited about the possibility that some of the moons in the outer solar system might have a global subsurface ocean of liquid water.
It's uncertain whether or not Jupiter's moon Callisto has a subsurface ocean, but some scientists think it might.
Let's imagine that a short distance below the surface, Callisto has a water layer 20,000 meters thick. Callisto has a radius of 2.410x106 meters.
Earth has a radius of 6.378x106 meters, and its oceans are equivalent to a layer of water 3000 meters thick all over the surface of the planet.
Which of the following is an accurate comparison of the Earth’s amount of liquid water with this estimate of the amount of water Callisto might have?
Group of answer choices
If this scenario is correct, Earth and Callisto have roughly the same amount of liquid water.
If these scientists are right, Callisto has about one-sixth as much liquid water as the Earth does.
If these scientists are right, Callisto has about 11 times as…
Titan is a moon of Saturn. Titan has wind erosion features. Would you expect Titan to have an atmosphere?
