I sincerely apologize, but recent (and unexpected) developments on the Hubble servicing front mean that I will have to cancel class today. Since I'll be out of town on Thursday, my plan has always been to not have class on Thursday, either. I WILL post more details on the term project, so hopefully you can use the time to work on that. Sorry about the last-minute notice, too. Have a good week!
