Henry Spencer

Henry Spencer is a systems programmer with sidelines in nonfiction writing, spacecraft engineering, and space history. He was a pioneer of open-source software, and wrote some of the early software for Usenet; his archive tapes were the base for Google's Usenet archive. He was head of mission planning for the (alas, defunct) Canadian Solar Sail Project, was software architect for the MOST astronomy satellite ("Canada's first space telescope," launched 2003), and now studies cheap planetary missions using nanosatellites, while writing software for Earth-orbiting nanosatellites. He helped found the Canadian Space Society, and is a member of the Senior Advisory Board of the Space Studies Institute. Asteroid 117329 is named after him.
