Microwelding (or cold-welding) of various metallic materials under the ultra-vacuum LDEF experiment AO 138-10The FRECOPA experimentation, as part of the Long Duration Exposure Facility (LDEF) mission, of mechanical and electrical parts of spacecraft in space ultra-vacuum has demonstrated freedom from any cold welding including microweld effects. This, as theorized, is due to integrity in space of the earthly grown oxygen layer. A further experimentation, a dynamic one this time, could provide a wealth of scientific data, yielding reliable material selecting criteria.
