There is strong evidence that Europa, a satellite of Jupiter, has a liquid ocean beneath its icy surface. Many scientists think we should land a vehicle there to search for life. Before launching it, we would want to test such a lander under the gravity conditions at the surface of Europa. One way to do this is to put the lander at the end of a rotating arm in an orbiting earth satellite.
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
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.

- NASA Scientists want to measure the current distance between two of Jupiter's Moons, Ganymede and Europa. They set up a laser on the surface of Ganymede, shine it at a mirror on the surface of Europa and measure how long it takes for the laser light to return to a detector on the surface of Ganymede. They calculated the current distance between the two moons to be 787 million meters. How long did it take the light to make it to Europa and back? *Give answers to at least three significant figures.

- We think the terrestrial planets formed around solid “seeds” that later grew over time through the accretion of rocks and metals. a) Suppose the Earth grew to its present size in 1 million years through the accretion of particles averaging 100 grams each. On average, how many particles did the Earth capture per second, given that the mass of the Earth is = 5.972 × 10 ^24 kg ? b) If you stood on Earth during its formation and watched a region covering 100 m^2, how many impacts would you expect to see in one hour. Use the impact rate you calculated in part a. You’ll need the following as well: the radius of the Earth is = 6.371 × 10 ^6 m and the surface area of the Earth is 4??^2Eartharrow_forwarda) What are the characteristics of a terrestrial planet? b) What are the characteristics of aJovian planet?arrow_forwardAssuming all other variables were earth based besides atmospheric pressure, calculate the temperature at which water would boil at sea level on Titan versus Earth?
