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.
Prompt: You are on the Sensor and Data Acquisition engineering team for the new NASA space rover program: the Unmanned Mobile Assessment Drone for Basic Reconnaissance and Observation. Your team is working with a very low budget, and have been given a hand-me-down drone which was repurposed from an old Mars mission.
The drone has already landed successfully on Saturn. It’s first task was to travel 4.6 m to a rock and then use it’s built in drill to take a sample. Unfortunately, it appears that the drone stopped very short, only traveling 1.32 m instead of the 4.6 m. Everything about the ultrasonic distance sensor that the drone uses to move with seems to be operating correctly. When you requested details from the drone, it said that the time it took for the 40 kHz ultrasonic sound wave to travel to the rock and back was 0.0108 seconds.
Why did the drone only travel 1.32 m, given the 0.0108s echo time?
Part of the "Mars Direct" mission plan involves rotating the spacecraft on its way to Mars to provide the astronauts with a simulation of Martian gravity.

- Even if the Europa Clipper can't send a lander down to Europa's surface, it may still be able to sample the sub-ice ocean during some of its flybys. How would this work? a The spacecraft would rendezvous with one of the large number of comets that we know are made of water erupted from Europa's ocean through its volcanoes. b There is some evidence that plumes of water shoot out of Europa, and the spacecraft could fly through them. c The spacecraft would crash into Europa, sampling the sub-ice ocean during the last seconds of its mission. d The spacecraft would drop powerful bombs onto Europa, shattering the ice and blasting some of the water into space to be sampled there.arrow_forwardA classmate claims that if Jupiter’s Galilean moons were all the same distance from Jupiter, they would all experience the same amount of gravitational force. Using what you have learned and the evidence from the data table how would you respond to his claim? (a) His claim is incorrect; if the moons were at an equal distance from Jupiter; then the pull of gravity would be the strongest on Ganymede because it has the greatest mass (b) his claim is incorrect; if the moon were at an equal distance from Jupiter; then the pull of gravity would be the strongest on Europa; because it has the smallest mass (c) his claim is incorrect; if the moon were at an equal distance from Jupiter; then the pull of gravity from Jupiter would be experienced equally by all four moons. (d) his claim is incorrect; if the moon were at an equal distance from Jupiter; then the pull of gravity would be the strongest on Ganymede because it is the largest moonarrow_forwardYou are elected as the chief engineer of a project to explore the whole Solar System.

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.
