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.
Which of these things did the Voyager spacecraft discover about Enceladus in the early 1980s, indicating that it is somewhat unusual among planetary bodies in our solar system? Check the TWO items that apply.
a It has a thick atmosphere, made mostly of nitrogen.
b It has the darkest, least reflective surface of all the known planetary bodies.
c It is the brightest (i.e. most reflective) object in the solar system.
d The entire surface is more heavily-cratered than any other body in our solar system.
e Its surface is very smooth in some places.
What is the escape velocity for Enceladeus in m/sec2 and could the plume particles form a ring around Saturn?

- 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?arrow_forwarda) How did scientists use Titan to guide Cassini on a tour of Saturn's moon system? b) What evidence supports the idea that a relatively recent catastrophic event wasresponsible for Saturn’s rings?arrow_forwardWhat element is notably deficient in Saturn's atmosphere, and why?
