>> *Space Debris: A Big Problem*(Georg Kirchner)
>> /When the first satellites were launched some 60 years ago, space was
>> more or less empty. However, the ever increasing launching activities
>> since that now have created a rather crowded environment above our
>> heads: More than 30.000 space debris objects – old / defunct
>> satellites, upper stages of rockets, remaining parts after explosions
>> of collisions etc. – are now orbiting in different altitudes, tracked
>> by radar, laser and passive optical telescopes. The possibility of
>> collisions is already rather high: Collision warning systems create
>> already more than 1000 warnings per day (!) of close encounters
>> between 2 objects – and sometimes this is TOO close – and a collision
>> between two space debris objects, at velocities of 27.000 km/h,
>> creates several 1000 new space debris parts…
>> Satellite Laser Ranging (SLR) has demonstrated during the last years
>> the capability of tracking such debris objects, helping to determine
>> their accurate orbit, and also their tumbling motions – important
>> features if you want to catch an old upper stage, and remove it from
>> space.
