Modular rockeTs Building Baffles - National Association of Rocketry

EDITOR’SDeath of the DreamWhen I was a kid, I had great hopes forspace exploration. Our manned space program,especially the Apollo Moon landings,made me so proud of America. It was a wayto fulfill the urge to explore, advance scientificdiscovery and technology, and demonstratethe greatness of the American systemin a peaceful endeavor. I remember a rocketcompany ad that said something to the effect,“The first people to walk on Mars arealive today, and they’re flying model rockets.”The future seemed so bright.After Apollo, the emphasis was to makespaceflight cheaper with reusable vehicles.We got a partially reusable Shuttle systemthat proved to be too fragile to live up to itspromises. For decades our astronauts neverventured beyond low Earth orbit.SPORT ROCKETRY(ISSN 08-83-0991, USPS 961-660) is published bi-monthly by the National Association of Rocketry,2275 Geode Street, Marion, Iowa 52302, 1-800-262-4872; a non-profit organization dedicatedto the growth of hobby rocketry.Email: nar-hq@nar.org World Wide Web: http://www.nar.orgPeriodicals postage paid at Marion, Iowa and at additional mailing offices.POSTMASTER:Send Address Changes to:Sport RocketryP.O.

With the cancellation of Orionand its Ares booster, we are not only limitedto low Earth orbit, we’ll have to hitch rides onRussian rockets to get there. The chance of anyonewalking on Mars during my lifetime nowlooks bleak. The likelihood that Congress isgoing to pass out the necessary billions of dollarsto private companies when no governmentagency is in control seems unlikely to me. Explorationdoes not turn an immediate profit, sothis sort of enterprise is best suited to whole nationsto finance. But it appears that our countryis no longer up to the challenge. I am heartbroken,and I mourn for the greatness that was theAmerican space program.Submission GuidelinesDeadlines for submission of material to SportRocketry magazine are as follows:Issue Cover Mailed DeadlineJan/Feb., 10 Jan. 4 Nov. 14, 2009March/April March 1 Jan. 15, 2010May/June May 3 March 12July/Aug.
