Greetings to all who are excited about the past, present, and future of space exploration.
Co-author Erika Lishock and I appeared on the radio/Internet program The Space Show last night to talk about this anniversary's meaning, and that show is archived at www.thespaceshow.com.
To put it all in a nutshell: no matter how big our other problems and concerns, humanity must never forget to look up and outward. It may sound romanticized, but it's still true: cultures which take their eyes off the horizon will never be what they might have been. We can still do great things together that benefit all of humanity.
