Editing Henry Spencer (section)

==Space==
Spencer is a founding member of the [[Canadian Space Society]], and has served on its board of directors several times since 1984. He did mission analysis (planning of launch and orbits) for the CSS's Canadian Solar Sail project (now defunct), and was Software Architect for [[Microvariability and Oscillations of STars telescope|MOST]], a Canadian science [[Miniaturized satellite|microsatellite]] dedicated to studying variable light from stars and [[extrasolar planet]]s launched by [[Eurockot]] in 2003.
The [[asteroid]] [[117329 Spencer]] is named in his honour.

He is a highly regarded space enthusiast, and is a familiar and respected presence on several space forums on Usenet and the [[Internet]]. From 1983 to 2007 Spencer posted over 34,000 messages to the sci.space.* newsgroups. His knowledge of space history and technology is such that the "I Corrected Henry Spencer" virtual [[T-shirt]] award was created as a reward for anyone who can catch him in an error of fact.<ref>{{cite web |title=About Yarchive.net |url=https://yarchive.net/about.html |first=Norman |last=Yarvin |access-date=2023-05-03}}</ref>
