Career
Kessler worked at the Johnson Space Center in Houston, Texas, as part of National Aeronautics and Space Administration"s Environmental Effects Project Office. While there, he developed what is now known as the Kessler syndrome, which posits that collisions between space debris become increasingly likely as the density of space debris increases in orbit around the earth, and a cascade effect results as each collision in turn creates more debris that can cause further collisions. Kessler first published his ideas in 1978, in an academic paper titled "Collision Frequency of Artificial Satellites: The Creation of a Debris Belt." The paper established Kessler"s reputation, and National Aeronautics and Space Administration subsequently made him the head of the newly created Orbital Debris Program Office to study the issue and issue guidelines to slow the accumulation of space debris.
Kessler retired from National Aeronautics and Space Administration in 1996, and lives in Asheville, North Carolina.
He continues to be active in the field of orbital debris. In 2009, he gave an address to the first International Conference on Orbital Debris Removal in Arlington, Virginia, co-sponsored by National Aeronautics and Space Administration and Defense Advanced Research Projects Agency. In 2011, he was a key adviser in the making of the educational IMAX film Space Junk 3D and also served has chairman of a United States National Research Council committee to assess National Aeronautics and Space Administration"s orbital debris programs.
In 2013, he gave a special lecture in Tokyo to the Second International Symposium on Sustainable Space Development and Utilization for Humankind, sponsored by the Japan Space Forum.
