(c) Meteoroid registration of the fluxes of micro meteorites and technogenic particles along the ISS flight route

(c) The split between damage from man made debris and micrometeoroids.

Man made debris and micrometeoroids meet these criteria for independence, except in cases of a recent break up or a meteor storm.

The tether apparently was severed by a micrometeoroid (or debris) on March 15.

satellite systems, micro and small satellites

In subparagraph (c), it is unclear whether the damage is caused by man made debris or a micrometeoroid.

micro satellites (theme 1)

Space Res., Vol. 17, No. 12, pp. 193 199, 1996. could then be analysed chemically and direction of impact permitted discrete populations of debris and meteoroids to be identified.

At altitudes of 500 km and below, the Unit has shown that micrometeoroids are more prevalent than man made debris.J.A.M. McDonnell, P. R. Ratcliff, S. F. Green, N. McBride, I. Collier, Microparticle Populations at LEO Altitudes Recent Spacecraft Measurements, Icarus, vol. 127, p. 55 64, 1997.

Consequently, the International Space Station will employ over 200 different types of orbital debris and micrometeoroid shields.

Perseids is one of the three major meteor showers in the Northern Hemisphere, and is most suitable for observation.

Look! A shooting star!

There is still discussion on the origin and nature of an apparent excess flux of either space debris or micrometeoroids in Earth orbit.

INMARSAT mini M

You mean, lofty star with humble player?

(d) Meteors and comets searches, confirmation, behaviour of central condensation and of comet tails, comet flares, comet rotation and comet jets

The main experiment on the satellite comprises monitoring of the behaviour of a fluid configuration called liquid bridge in microgravity conditions.

Ah, stella cadente.

He's a meteor.

Don't mix up comets and asteroids.

Scientists discovered this large scale flow by comparing the motion of the local group with respect to clusters versus the motion with respect to the cosmic microwave background, which is assumed to be a quot stationary quot reference.

Mobile satellite services

The satellite belongs to the International Mobile Satellite Organization (Inmarsat).

Since Ku and Ka band capacity are considerably cheaper than L band (used for the INMARSAT M system), this Picoterminal is also interesting from an economic point of view.

Professor Van Allen told me about observations of Venus, that there was intense microwave radiation.

The ISL in the global satellite projects used microwave radiation as the carrier.

A hazard for space objects and orbital stations is posed by hypervelocity impact with meteoroids and space debris particles 1 2 mm or larger.

It's about that meteor.

The stars don't care to watch me

The impacts of the Shoemaker Levy 9 fragments on Jupiter caused the formation of micron sized dust particles.

Thereafter, SEDS 2 remained in space to determine the resistance of its braided polyethelene to micrometeoroids, space debris, and atomic oxygen.

And using different microsatellites gave the different results.

And what starts happening is that, around young suns, young stars, all these elements combine, they swirl around, the energy of the star stirs them around, they form particles, they form snowflakes, they form little dust motes, they form rocks, they form asteroids, and eventually, they form planets and moons.

So, right now, we can actually miniaturize biological and chemistry laboratories onto microfluidic chips.

Tomorrow we are going to see the meteor shower!

A falling star blown away by the wind,

Thirdly, a beam park mode of operation with compensation of the Earth rotation to get information on the meteoroid influx during major meteor stream activities.

And you see the amount of detail that is in those rings, which are the particles.

This microsatellite is intended for research of the Earth apos s gravitational field.

The instrument is presently measuring charged particles streaming outwards from the Sun (the Solar Wind) into interplanetary space Detection range 40 keV to several tens of MeV).

The picture that emerges from these and other measurements is that the debris population exceeds the natural meteoroid population for all sizes (except between 30 and 500 μm).

This is a microfluidic chip that I developed.
