Man-made space waste and healthy meteoroids relocating during high speed can repairs satellites and consecrate a critical jeopardy to spaceflight, generally tellurian spacecraft.

Typical impact speeds encountered by satellites are 10 km/s for space waste and 20 km/s for meteoroids – some 10–20 times faster than a bullet from a gun.

Measuring approximately 15×15 cm across, a image displayed outward a Materials and Electrical Components Laboratory of ESA’s ESTEC technical centre in Noordwijk, a Netherlands. The categorical hole, seen here, measures 28×12 mm across, with a few smaller adjacent holes.

ESA engineers typically use numerical simulations to investigate a intensity effects of hypervelocity impacts on missions.

In addition, ground-based hypervelocity tests are achieved during several exam sites in Europe. Light gas guns are accessible during a Ernst-Mach Institut (Germany), CISAS (Italy), Centre d’Etudes de Gramat (France), The Open University and University of Kent (UK).

Electrostatic accelerators, also used for hypervelocity testing, are used during a Max-Planck Institut für Kernphysik (Germany), The Open University and a TU Munich.
