Former NASA astronaut Scott Carpenter, the second American to orbit Earth, will talk about his new book, "For Spacious Skies: The Uncommon Journey of A Mercury Astronaut" on Tuesday, March 4, at 5:30 p.m. at the University of Colorado at Â鶹¹ÙÍø. The talk is in the Old Main Chapel and is free and open to the public. Initially scheduled for January, the talk was rescheduled after a death in the Carpenter family. Kris Stoever, Carpenter's daughter, co-authored the book and will take part in the discussion.
