The Technologies and Systems for Space Debris Remediation

DURATION: THREE DAYS
LOCATION: AT YOUR FACILITY
COURSE NO.: 1065

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. Hundreds of debris items are added each year from new launches, failure of spacecraft and collisions. Mitigation approaches have been pursued and many reduction techniques have been suggested. A limited number of spacecraft are now able to maneuver out of the way at end of life. But, little is being done to reduce existing debris or to limit new debris. This timely course explains the dangers and 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 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., Canada, 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 Fellow of the AIAA and a member if its Technical Committee on Space Transportation. He holds advanced degrees from MIT and Stanford University.
