The debris plumes resulting from penetration experiments using soda-lime glass projectiles (3.2 mm diameter; at 6 km/s) and aluminum 1100-0 targets (1.0 and 0.8 mm thick) were intercepted with blued Cu-witness plates some 6, 12 and 49 cm from the tar

When Orbiter Vehicles (OV) are placed in low-Earth orbit (LEO) the exposed surface is subjected to hypervelocity collision with small particles of meteoroids and man-made orbital debris (M&OD). The external shell of the orbiter is specifically design

To assist in the interpretation of crater populations on space-exposed surfaces from the Solar Maximum Satellite and the Long Duration Exposure Facility (LDEF), we conducted laboratory simulations of cosmic-dust impacts into aluminum 1100 targets wit

Approximately 20 sq m of protective thermal blankets, largely composed of Teflon, were retrieved from the Long Duration Exposure Facility after the spacecraft spent approximately 5.7 years in space. Examination of these blankets revealed that they co

Summary Spherical soda-lime glass projectiles 50, 150, 1000 and 3175 μm in diameter (Dp) in aluminum targets (series 1100; “annealed”) of variable thickness T, were used to determine how the penetration-hole diameter (Dh) varied as a function of
