The even-numbered assignments in HAS all require me to design something, describe it, and draw it. This assignment is number 9, and I had to consider solutions for an issue with going to Mars, which I thought would automatically involve designing and describing (but not drawing; it's odd-numbered) a lander or something until I saw that one of the issues I could come up with a solution for is timekeeping. MUCH easier than designing a lander, in my opinion.
