Carl Sagan’s rationale for human spaceflight

every surviving civilization is obliged to become spacefaringnot because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive. Hello Gang, In the interval between theroast Turkey and the Christmas Pudding I took a break from the sheer gluttony of this wonderful day bysurfing the Internet and came across a very interesting article I found on the Space Review web site entitled "Sagans rationale for human spaceflight" at http://thespacereview.com/article/261/1 If we all manage to survive the closing days of the month and survive the New Year's Eve binge of ethanol I look forward to discussing the issues raised in the article by Michael Huangand Sagan himself. Stay safe one and all and may the coming new year bring you much good fortune and great joy. Love and Happiness to you all. Happy Holidays everybody, Alex Michael Bonnici
