Debris and Long-Term Sustainability 14th NASA/DoD ODWG Meeting 2 of Activities in Outer Space NASA/DoD Meeting Space Debris has been an agenda item for In 2010 the subject of long-term sustainability on Active Debris each annual meeting of the Scientific and Technical of activities in outer space was added to the Removal 2 Subcommittee of the United Nations’ Committee Subcommittee’s agenda, and a working group was Kessler Receives 2011 on the Peaceful Uses of Outer Space (COPUOS) formed under a multi-year work plan. At the 2011 Dirk Brouwer Award 2 since 1994. In 1999 the Subcommittee produced meeting of the Subcommittee, terms of reference Russian Launch its first major assessment on the topic, Technical for the working group were established.

The collision between presented the Dirk Brouwer Award to Donald J. Iridium 33 and Cosmos 2251 in 2009 underlined Kessler during the 21st AAS/AIAA Space Flight the potential collision cascade effect, commonly Mechanics Meeting in New Orleans in February. known as the “Kessler Syndrome,” based on This award was established by the AAS to honor his pioneer work in modeling the near-Earth significant technical contributions to space flight orbital debris environment in 1978. For half a mechanics and astrodynamics. It is the most century, Kessler dedicated his research to various prestigious award presented by the AAS. The aspects of the orbital debris problem, from award to Kessler reads “For first recognizing, measurements to modeling, at both national and then defining and researching the Earth’s orbital international levels. He was awarded the NASA debris hazard during an illustrious half-century Medal for Exceptional Scientific Achievement career in astrodynamics.” in 1989. He retired from NASA in 1996 as the Kessler is considered by many to be the Senior Scientist for Orbital Debris. Kessler Kessler receives the 2010 Brouwer Award from Professor Dan Scheeres, Chairman of the AAS Dirk father of orbital debris research. His early is also the recipient of many other awards, Brouwer Award committee. efforts in understanding the orbital debris including the 2008 IAASS Jerome Lederer Space problem led to the establishment of the NASA Safety Pioneer Award. ♦ Orbital Debris Program Office at the Johnson 2 www.orbitaldebris.jsc.nasa.gov Russian Launch Vehicle Stage Reenters Over U.S. In January 2011 the Russian Federation On 22 March the Sheriff ’s office successfully tested a new launch vehicle to insert of Moffat County, Colorado, contacted its next generation of meteorological spacecraft the NASA Orbital Debris Program into geosynchronous orbit.
