Seradata is sad to note the passing of Frank Sietzen Jr. at the relatively early age of 65. Frank Sietzen Jr. has been a professional space writer for three decades, writing for Space Business News, space.com, the American Institute of Aeronautics and Astronautics and as editor-in-chief of Ad Astra. Sietzen was also an expert on space policy and spaceflight history and wrote several books including the World Guide to Commercial Launch Vehicles, The Astronaut and the Fireman, Project Constellation, and co-wrote New Moon Rising with Keith Cowing. Sietzen did not only write for publications. He was, at one time, speech writer for Charles Bolden, the Administrator of NASA, as well as being President of the Space Transportation Association.
