Feedback collisions, i.e. collisions where one or both objects are fragments generated by previous collisions, will not play any significant role within the next 100 years, according to this conservative model.

This means that collisional fragments will contribute to the number of subsequent collisions.

It's just a log bumping.

Collision analysis function to detect space debris that has high risk to collide with certain space systems

And testing breakaway signpost pillars.

Collisional cascading will not set in during 100 years, since most of the destructive collisions will occur between the members of the background population and not between collision fragments.

Was it possible to avoid impact?

I'll run into you by accident.

The chances were you wouldn't have missed it.

Cannot finish this step because there are collisions which cannot be resolved automatically. Please move colliding objects apart and try again.

He bumped his head against a post.

Effective measures to mitigate the consequences of break ups caused by collision include the spacecraft design, selection of an orbit where the probability of collision is low, and collision avoidance manoeuvres (see paragraphs 112 118 below).

provided a large surface area of exposed surface which could be examined for impact sites. Through the application of empirical impact formulae relating the material characteristics of both impactors and spacecraft surfaces and the impactor speed and incidence to these surfaces to impact features, it was possible to infer the encountered micro debris environment by counting, measuring and chemically analysing the residue observed in impact sitesW.

But collision is a serious problem.

Number and location of collisional break ups.

But they will eventually bump into each other.

Such analyses also require some impact calibration tests to study the response of unique array materials to hypervelocity impact.

However, in the future, the interactive risk for so called destructive collisions, i.e. collisions that generate larger fragments, may increase.

9. On orbit collision avoidance (for LEO)

Even if he has to kiss the pylons.

More than a hundred impact test data have been obtained in the impact velocity range of up to 5 km s using a two stage hydrogen light gas gun.

The Subcommittee noted that collisions of near Earth objects with the Earth had occurred in the past and that the largest and most recent collision had occurred when the Tunguska meteorite had fallen on the territory of Russia in 1908.

Collision avoidance is always probabilistic.

(c) Break ups (produced by explosions and collisions)

In order to assess the consequences of collisions among larger objects, it is necessary to have reliable break up models for collisions of this type.

And as you can see, the risk of collision is much lower.

Over 70 impact sites were clearly identified.

A total of 704 large impact features were recorded.

And when they do, they're just drifting past each other.
