Radar has been the most effective means of observing LEO (low Earth orbit) debris of quot threatening size, quot which is debris pieces larger than about 1 cm.

It was important to prevent a proliferation of such debris in the future and to minimize the risk of collisions between pieces of debris and satellites or other aerospace objects.

Man made sources of debris included anything that had been put into orbit and was no longer useful, most debris being pieces smaller than 10 centimetres in diameter or tiny particles.

At this time, China has also put forward a method of solving the space debris problem, and that is, to use a large laser to shrink the floating space debris into smaller, less harmful pieces.

(e) Determine the internal structure of the asteroid, in particular the sizes of the main solid pieces, the average particle size and thickness of the regolith and of the debris layers in the space left between the main pieces

The amount of existing debris is considered to far exceed that currently identified by NASA (at 13,000 large pieces), especially at the most heavily used Lower Earth Orbit.

So three pieces of data for each country three pieces of data.

I want pieces. Bits and pieces.

Pieces of jam.

The Subcommittee agreed to focus on understanding aspects of research related to space debris, including debris measurement techniques mathematical modelling of the debris environment characterizing the space debris environment and measures to mitigate the risks of space debris, including spacecraft design measures to protect against space debris.

1. Measurements of space debris

Amongst the topics discussed were short term and long term debris hazard modelling, ground based optical and radar detection of debris objects, measurement of the micro debris through the analysis of retrieved surfaces, and international initiatives relating to space debris.

We can still make the pieces. We can make the right pieces.
