Mechanical properties of bulk structural metals are very little affected by space environment except for probability of penetration by meteoroids; fatigue life of flexed structural materials in simulated space vacuum has been studied and it has been shown that fatigue life is decreased; however, other studies have shown that reverse is true; planning of programs for long lived satellites (of order of 1 yr in space); multimanned satellites, manned space stations, missions, manned and unmanned, to moon and planets, and orbiting astronomical observatories, have imposed more exacting demands upon reliability of properties of materials for aerospace applications.
