Still working at the Harvard College Observatory and loving it. Writing, teaching and trying to find good ways to make space science concepts accessible to students of all ages and general audiences. I have lived in Lexington, Mass., for the last 40 years, about one mile from the Battle Green where the first Revolutionary War conflict occurred. All our children (four) and grandchildren (three) live within 15 minutes of us -- wise choices we believe! I will not be able to attend our 50th since it conflicts with a family graduation here in the Colonies, but I have #55 on my calendar.
