How is Kessler Syndrome prevented?

There is no current system to remove old satellites or sweep up bits of debris in order to prevent a Kessler event. Instead, space debris is monitored from Earth, and new rules require satellites in low-Earth orbit be deorbited after 25 years so they don’t wind up adding more space junk.

Why is the Kessler Syndrome a concern?

The Kessler syndrome is troublesome because of the domino effect and feedback runaway wherein impacts between objects of sizable mass spall off debris from the force of the collision.

Is Kessler syndrome likely?

In spite of several commentators warning that these collisions are just the start of a collision cascade that will render access to low Earth orbit all but impossible – a process commonly referred to as the ‘Kessler Syndrome’ after the debris scientist Donald Kessler – the reality is not likely to be on the scale of …

What is the Kessler syndrome?

The Kessler Syndrome is a theory proposed by NASA scientist Donald J. Kessler in 1978, used to describe a self-sustaining cascading collision of space debris in LEO.

Did the Iridium-Cosmos collision in 2009 cause the zero-Kessler’s syndrome?

Kessler’s Syndrome refers to a cascading effect of colliding debris creating additional debris and additional collisions, but time frame is not inherent to the model. This means that the Iridium-Cosmos collision in 2009 could have ignited the process, kind of like a “Patient Zero,” though it’s been slow-to-burn.

What is the significance of Kessler’s paper?

Kessler’s paper was significant because it emphasized the imminent danger of small debris in orbit as well as the inevitably of additional debris produced from collisions with catalogued objects. Kessler suggested the best way to avoid the exponential growth of the collisions was to reduce the number of non-operational spacecraft left in orbit.
