Campus Librarian Presented
Space Debris Proposal to NASA
interview and photos in Golden Library by Wendel Sloan
"ENMU has been very good to me, and I feel fortunate to be a part of this institution." – Sean Shepherd
Editor's Note: The following interview is with Sean Shepherd, Circulation Supervisor/Instructional Resource Coordinator at Golden Library. He has also presented a proposal to NASA about a cost-effective way of capturing space junk.

Q. When did you begin working at ENMU?
A. In August of 2006.
Q. What are the main duties of your job?
A. General library duties, and I supervise one staff member and up to 17 student employees.
Q. What have you enjoyed most about your job, and what have been the biggest challenges?
A. Working in a research environment and helping students with their library needs is the most enjoyable. The most challenging is getting library materials returned.
Q. Tell us about your proposal to NASA about capturing space junk?
A. It has been an educational experience. Although my concept is among the most feasible presented, nothing will be done about the space junk crisis until the United Nations deliberates on whose trash is whose up there, and it is projected that it could take up to 50 years before a decision is made. Meanwhile the space junk is cascading and causing several orbital hazards.
The concept utilizes large metallic foam spheres (about average room size). The spheres would be coated with a space friendly formula of Aerogel, which are placed in orbit to intercept ‘clouds’ of small pieces of orbital debris which would imbed into the spheres and aerogel. My estimation was to capture approximately 100 pieces per sphere, however, NASA estimated up to a thousand in their 66-page report from the First International Orbital Debris Conference where I presented.
The report also stated that if the spheres were ‘mission ready’ it could be tested in the distant future. Once the spheres have captured enough debris, a ‘solar sail,’ which would be attached to each sphere (about the size of a pizza box) would be deployed gathering enough energy to guide the spheres out of orbit using U.A.V. guidance technology. Several spheres could be launched at once using ballistic missile technology, but, instead of launching multiple warheads, multiple spheres would be launched. It was the least expensive solution presented, and was the only concept out of 49 that would have debris smash into the spheres, rather than using a vehicle or laser to chase down the junk.
NASA and DARPA are currently more interested in capturing larger debris such as used satellites or spent rockets, however, the cascading crisis for smaller debris has become more critical of a problem as small pieces smash into satellites, space vehicles, and the space station itself. Cons of the concept include trajectory issues that could arise from junk sending spheres into undesirable orbits, or the spheres crashing into mission essential objects.
Some kind of advanced guidance technology could fix those problems. A prototype sphere built for testing would cost approximately $40,000. Meanwhile, I have secured the concept as intellectual property, and simply hope that something will be done to clean up all that trash up there.
Q. What were you doing before you came to ENMU, and what other jobs have you held?
A. I have served in the military, worked as a patient administrator and ordered surgical supplies for the University of Utah. I have also sold appliances and managed a lodge in Ruidoso, and have taught secondary social studies. I have also worked at the Portales Public Library and Cannon Air Force Base library.
Q. What are your degrees and majors?
A. I have minor's degrees in in patient administration, and greater southwestern studies. I have a B.S. in history, and an M.Ed. with emphasis in social studies.
Q. Where were you born, raised, and what was your life like growing up?
A. I was born in Ogden Utah, and raised in Roswell I had an excellent childhood; my father is a graphic printer and my mother was a bus driver – now a social worker.

Q. Your own family?
A. I have two sons, 19 and 12.
|Sean with sons Tovian and Steaphan|
Q. What are your hobbies?
A. Playing Axis and Allies board games, studying the Arab-Israeli conflict, reading and watching documentaries.
Q. What is your ultimate career goal?
A. I want to pursue a doctorate in history, and instruct at the college level.

Q. What gives your life meaning? Besides career goals, what else do you hope to accomplish?
A. Everyday news updates. I also hope to develop a business idea for our community – which is in the works.
Q. What is your general impression of Portales, and ENMU?
A. On the day I moved here as a student, 18th Street was flooded and a wave literally hit my windshield and I could not wait for the moment I could get out of this town. However, Portales has become a cherished home and ENMU has been very good to me, and I feel fortunate to be a part of this institution.
