strategies: comparison between electrostatic plasma brake and conventional propulsion.
Clean Space will also develop techniques to mitigate the problem, such as passive and active deorbiting
devices and the means to 'passivate' retiring satellites.
317) These postmission deorbiting
options are currently "advocated by the major space-faring nations and organizations of the world, including NASA, the Department of Defense, the Department of Transportation, and the Federal Communications Commission in the United States.
The satellite's expected deorbiting
time from a 660 km sun-synchronous circular LEO is predicted to be 23 years and its designed operational lifetime 2 years .
SERVICING, AND DEORBITING
EARTH SATELLITES USING ROBOTICS 119
Secondly, research should be increased on methods of deorbiting
critical pieces of debris safely and effectively.
has considerable resources available for the media related to the upcoming deorbiting
of the Mir space station: a debris study center, an in-depth Web site, a video depiction of the event, space debris artifacts and subject experts.
Satellites generally stay in the orbit until removed by natural deorbiting
Santerre and colleague Max Cerf have been working on what they call the Innovative DEorbiting
Aerobrake System (IDEAS).
On March 17, 2004 and on April 1, 2004, our PAS-6 satellite suffered anomalies resulting in a loss of power and the deorbiting
of the satellite.
Motorola will maintain the Iridium satellite system for a limited period of time, while the deorbiting
plan is being finalized.
The related concept of electrostatic plasma brake for deorbiting
a satellite  is only briefly touched upon in Section 3, otherwise it is left out of the scope of this paper.
