(f) Ground based simulations of explosive fragmentations.

Frangible discs shall rupture at nominal pressure equal to the test pressure of the shell.

Two break ups (one a spacecraft and one an upper stage) have been identified, and some evidence suggests that additional break ups may have occurred.

The number of major collisions predicted by several models (EVOLVE, CHAIN, CHAINEE and IDES) are presented as envelopes of predictions in figure VII. The number of fragments generated by future sources is less consistently predicted for small fragments.

3.1.2 Prevention of on orbit break ups

When no spring loaded pressure relief device is used, the frangible disc shall be set to rupture at a nominal pressure equal to the test pressure.

(d) Fragmentation (leading to a loss of large objects).

Intentional break ups have also been conducted.

Debris detectors.

In addition, the possibility of other break ups being caused by collision cannot be denied because the causes of many break up events remain unknown.

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

Amongst the topics discussed and presentations given were optical and radar detection of debris in orbit, prediction of solar activity and atmospheric response, design of optical systems to detect debris, prediction of the long term evolution of the orbital debris population, unmodelled sources of debris, the inferred microparticulate population encountered in orbit as derived from examination of retrieved space exposed surfaces, and hydrocode modelling.

1.2.2 Space based debris measurements

(c) is manufactured from material which will not fragment upon rupture

Such fragmentations are caused by either explosions or collisions.

Radar measurements of ARIANE upper stages in GTO will help to understand the generation of space debris due to fragmentation in these orbits.

The frangible disc shall rupture at a nominal pressure 10 above the start to discharge pressure of the relief device.

The frangible discs shall rupture at a nominal pressure 10 above the start to discharge pressure of the relief device.

The Mars 96 station entered the dense layers of the atmosphere and broke up, with individual fragments falling into the water areas of the Pacific Ocean

After careful examination, it can be seen that the skull was smashed to pieces.

A disintegration event of this type has never been observed before.

It does save getting splinters in your knuckles.

1. Measurements of space debris

A. Observation of space debris fragments

Optical facilities for debris observation

Smaller fragments stem mainly from break up events in these highly eccentric orbits.

12. The debris produced by upper stage fragmentations now accounts for more than 30 per cent of the catalogued Earth orbiting object population.

They try to tear the boils right out of their flesh.

Further simulations on the evolution of debris clouds in this altitude regime will be undertaken in order to better understand the short term flux increase as a function of the break up location and parameters.

Business as Usual current launch rate and in orbit break up rate

Such fragmentations are caused primarily by either explosions or collisions.

(b) Currently, depending on size, fragments from explosions are the main source of space debris.

Typically, radar measurements have been used for space debris in low Earth orbit (LEO), while optical measurements have been used for high Earth orbit (HEO).

The observations are also revealing sources of debris that were not predicted.

The permanent elongation at fracture shall be measured on test specimens of rectangular cross sections in accordance with ISO 6892 1984 using a 50 mm gauge length.

It broke up through atmospheric pressure, it crumbled, and then the pieces fell apart and did some damage.
