(High altitude) plodad or fractured; seals may leek; air bubbles In materials may ex. plodse causing damage; Internal heating may Increase due to lack of coolino mwedium; Insulations may suffer arcing and breakdown, ozone may be formed,, outgasslng Is more likely.

Goale Corrosion of metals may be accelerated; dielectric strength may be reduced; an explosive environment can be created; heat transfer properties may be altered; oxidation may be accelerated, Acceleration Mechanical overloading of structures; iteris may be deformed or displaned;, mechanical functions may be impaired. Vibration Mechanical strength may deteriorate due to fatigue or overstress, electrical signals may be mechanically and erroneously modulated, materials and structures may be cracked, displaced, or shaken loose from mounts; mechanical functions may be impaired; finishes may be scoured by othe isurfaces; wear may he Increased.

Shock Mechanical structures may be overloaded causing weakening or collapse; itams may ba ripped from their mounts; mechonical functions may be Impaired, Nuclear/cosmic radiation Causes hqating and thermal aging; can al oar chemical, physical, and elec- trical properties of materials; can produce gase and secindlary radi- ation; can cause mxidat~on and discoloration of surfaces; damallis electrical end electronic components, especially semiconductors, Thermal radiation Causes hosting and possible thermal aging; surface deterioration; structural Weakening; oxidation; acceleration of chemical reactions,, end alteration of physical and electrical properties, RFI Causes spurious and erroneous signals from electrical and electronic equip- ment and componants; may cause complete disruption of normal electrical and electronic equipment such as uommunication and Mea- suring systems, Solar radiation Effects similar to those for sunshine, nuclear/cosmic radiation, and thermal radiation.

Albedo radiation Aibodo radiation is reflected electromagnetic (EM) radiation; amounts de- pend on thr reflective capabilities of illuminated object such as a planet or the moon; effects are the somne as for other EM radiation, Zero gravity Disrupt gravity-dependent functions; aguravatas h igh -temperature effects,
