Using MATLAB, python, or another programming language, plot orbits with eccentricities of 0.0. 0.2, 0.4., 0.8 such that a = 15,000.0 km. Include all orbits on the same plot. See Lecture 8. Slide 24 for a similar plot. Provide the plot in your write-up, and include a circle for the primary body with radius R. Which of these are viable orbits for a spacecraft? Hint: Generate the spacecraft position in polar coordinates (r and 0), and then con- vert them to Cartesian position for plotting.
