Listening to this program within a cultural reflection of a surge of interest in form of books, films and general presence as a topic - this is really going to happen! The egoistic part of me hopes that I'll be still around to witness the biggest continuous news story being a good one. One thing I'd have liked to hear a little more about is the current state on radiation affairs, one the biggest problems upon leaving the parking lot. The good folks with CERN are working on a promising approach, a superconducting shield to create a magnetic field around spacesuits and -crafts: A question how it'll work out schedule-wise, but very exciting, I say.

Great new arrangement to the theme tune! Sounds just like a Movie Blockbuster with hints of Star Trek, Battlestar, and more...
