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?
Pretend you are a NASA executive or a legislator. Design a new mission in our solar system.
Pick any object in the system and decide whether you want to send an orbiter, a lander, a
rover, some combination or those, a manned mission, or something else. What interests you about
this object? What science questions can we answer? In basic terms, what kind of scientific
instruments might you want to include on your mission? Justify your decisions with what you
know about the scientific method, astronomy techniques, and the object itself from this class.
Your goal is to try and make the timeline of the Perseverance mission play out the way you remember it. You want to make sure that the Perseverance rover gets built and sent to Mars, just like your "memory of the future", i.e. your memory of the summer of 2020.
In the space provided below, write a description, in your own words, of why the Perseverance rover has the potential to do great science. Here are the things to focus on: What are the two or three most special things about Perseverance, when it comes to the search for possible ancient life on Mars? In particular, you want to make sure to describe and explain the one particular thing that Perseverance will hopefully do, which will start the long process of giving scientists the opportunity to learn about Mars in a way they never could do before.
