Studies should be continued on future possible solutions to reduce the population of on-orbit debris. It was pointed out, that there is a need to improve our understanding of the environment particularly up to 2000 km altitude and in the geostationary ring. There is a need to lower the threshold for tracking debris to a few centimeters. This can be achieved with higher power radars and improved optical telescopes. More accurate space debris models are needed which provide the particulate flux at different altitudes and for a large range of object sizes.
Further research is required in the areas of hypervelocity impacts and shielding.
The modeling and simulation capabilities should be extended to cover the full range of collision velocities in space. It was also pointed out, that space debris is part of a wider problem, that of the use and management of outer space. More attention should be paid to operational satellites which offer numerous capabilities and benefits in many areas. The number of active satellites is approximately 600, of these about 250 are in the geostationary orbit. Maybe some form of space traffic control will be needed in the future.
