When Debris Overwhelms Space Exploitation
(Launchspace Staff Writers)
Bethesda, MD - We see more and more reports of debris concern among satellite operators and space observers. Add to this the many recent announcements of multiple broadband satellite constellations that are being funded and developed for launch in the next few years. Just focusing on low Earth orbits (LEO), there are an estimated 15,000 satellites in the works. For example, Amazon is planning to launch 3,236 satellite and SpaceX is already building the first of 4,000 multi-hundred-kilogram spacecraft. Add all of the broadband satellites to the hundreds of planned CubeSats and we have a new satellite population that is at least an order of magnitude larger than what is now in LEO. This explosion in population will be accompanied by an explosion in debris. The safety and traffic implications are extremely negative.
Assuming no debris removal and control program is implemented, it is estimated that within the next decade the debris population will overwhelm LEO operations to the point that space access may be completely impossible. This cannot be allowed to happen because the world's economy will be set back for at least one or two generations. Since the military depends heavily on space, national defense capabilities will also be seriously diminished. Just imagine not having GPS, direct-to-home TV broadcasts, satellite weather, missile defense detection and many other services we now take for granted.
Once the debris takes over, there is no known way to then clean up space. It is fair to say that such a cleanup, if possible, could take decades or even centuries. Without space our technological future will be quite limited. Even our present way of life will disintegrate and revert backward by at least 20 years.
The bottom line is that this cannot be allowed to happen. Somebody has to pay to cleanup space, and that somebody is going to be everybody on the planet, one way or another. To paraphrase a popular muffler ad: "You can pay now, or you can pay later. However, the cost is going to be much, much higher if we wait."

Space Debris: Issues, Threats and the Equatorial Epiphany
DURATION: THREE DAYS
LOCATION: AT YOUR FACILITY
COURSE NO.: 1060
COURSE SUMMARY
Since 1957, artificial satellites and launch vehicles have created an ever growing number of orbiting debris objects, from a few microns to several meters in size. In recent years a number of international agreements have been made to limit the growth rate of debris. However, there is no serious program to reduce the amount of existing debris. Recent developments such as the proliferation of debris from the Chinese ASAT test of 2007 and the 2009 collision of an Iridium satellite with a Russian Cosmos have raised level of urgency to actively manage the debris situation. Mitigation approaches have been pursued and many reduction techniques have been suggested. Many new spacecraft are now able to maneuver out of the way at their end of life. But, little is being done to reduce existing debris. This special and timely course introduces the Equatorial Epiphany and attempts to explain the dangers and the options associated with the growing debris problem.

INSTRUCTOR: DR. MARSHALL H. KAPLAN
Marshall H. Kaplan, Ph.D., is a recognized expert in space flight technologies, orbital mechanics and debris retrieval. He was the first to study space junk retrieval and was instrumental in the safe reentry of the Skylab Space Station in 1979. Foxnews.com recently aired a story about his four decades of research on this topic. Dr. Kaplan is one of only a few experts in the field of space debris control and reduction. He has over four decades of academic and industrial experience, having served as Professor of Aerospace Engineering at the Pennsylvania State University and presenting hundreds of courses on space technology in the U.S., Europe, South America and Asia. In addition to publishing some 100 papers, reports, and articles on aerospace technologies, he is the author of several books, including the internationally used text, Modern Spacecraft Dynamics and Control. Dr. Kaplan is a member of the AIAA Technical Committee on Space Transportation and holds advanced degrees from MIT and Stanford University.
