ISS Science for Everyone

Science Objectives for Everyone
Recording Micrometeoroid and Technogenic Particle on the External Surface of the ISS Russian Segment Service Module (Meteoroid) continuously monitors the meteoric and space debris environment in the proximity of the orbit of ISS operations. This is determined on one hand, by the continuous increase of the pollution level in the space environment, and on the other hand, by the ISS design life. The Meteoroid experiment is one component of a system being developed to monitor the meteoroid and technogenic elements of the space environment, covering the full range of the particle sizes.

Space Applications
Meteoroid will aid in updating the Russian models of the technogenic environment in the range of small-sized particles (< 0.1 mm), which is characterized by significant dynamics in time, and specifically, for updating the developed model of the penetrating shower of meteoroid and technogenic particles with sizes 20 – 100 micron impacting thin barriers and to verify the predictions of the arrival time and intensity of meteor showers.

Earth Applications
The Earth Application for this investigation has yet to be identified.

Results/More Information

The comparison of the data on MMOD showers obtained as a result of the Meteoroid experiment to results from orbital stations Salyut and Mir and other space objects, as well as to modeled values of the showers showed that in the range of particle sizes over 20 micron, there is an increase in the pollution levels of the near-Earth space environment over time for orbital altitude ranges 400-500 km (more than doubling over 10-15 years). For the range of particles with sizes below 20 micrometers, such effect is not observed as a result of a more intensive self-cleaning of the space environment at these altitudes from smaller-sized micro-particles due to aerodynamic deceleration and solar radiation pressure.
