The glider.py file (which you should not modify, but may examine or import) implements the simulated glider. The opensimplex.py file (which you can safely treat as a black box and should not modify) is used when generating the map function. The marsglider.py file contains two functions that you must implement, and is the only file you should submit to Canvas->GradeScope. Part A The first function is called estimate next_pos, and must determine the next location of the glider given its atmospheric height and the radar distance to the ground. If your estimate is less than 5 meters from the target glider's actual (x,y) position, you will succeed and the test case will end. Note that each time your function is called, you will receive one additional data point, and it is likely you will need to integrate the information from multiple calls to the function before you will be able to correctly estimate your glider's position. The "OTHER" variable is passed into your function and can be used to store data which you would like to have returned back to your function the next time it is called (at the gliders next timestep). Note that in part A you are not able to modify the gliders path, so it will be gliding in a (relatively) straight line
