This issue of The Earth Observer marks the thirtieth anniversary of the publication of our first issue (March 1989)—shortly after the official beginning of NASA’s Earth Observing System (EOS) Program. At that time, when the Internet was still in its infancy, print media was the best way to get the word out about the program, meetings, results, announcements, and the like to hundreds of interested researchers across the country and the world. Enter The Earth Observer!
