220510 – Hey, folks - I honestly have nothing to talk about today, so the last lecture... was last Thursday. (No class today.) I will be on Zoom (434 305 7745) during class time today if you have any questions or anything. Thanks for the great turnout throughout the term, and I hope you found the course valuable. Looking forward to seeing your final projects!
220407 – Today's class is cancelled. I encourage you to use the time to work on your projects. Remember, I’m looking for informal progress reports next week. E-mail me or use the chat function here if you have any questions. Sorry about the late notice.
220301 – Due to a number of things all coming together at the same point in time, I am going to cancel today's class (Tuesday, March 1). I'll try to send this out in a number of ways to make sure everyone sees it before coming in. Sorry about the late notice.
220228 – I screwed up by not checking Problem Set 2 before publishing it - the entry orbit has enough energy to skip out of the atmosphere rather than perform a direct descent. Please reload the revised problem set to see the options available to you. Sorry about that.
