![]() For example, many adhesives outgas, potentially releasing volatile products which condense and contaminate electronic, optical, and other precision instruments. Otherwise, contaminants put off by the adhesive can fog and degrade the lenses.Īdhesives on spacecraft are often near electronic or optical devices, where contamination can lead to serious problems. Optics for space applications can be protected by using low-outgassing adhesives. They must function properly despite the surrounding conditions without degrading other spacecraft components. But whether directly exposed to space or not, most adhesives employed in space applications are subject to high vacuum and extreme cold. Most adhesives used on spacecraft are not exposed to atomic oxygen or ionizing radiation because they are inside or sandwiched and protected between parts they are holding together. And in interplanetary regions and deep space where space probes travel, high temperatures and intense radiation are of particular concern.Īdhesives and other polymers are used extensively in all types of spacecraft for structural, mechanical, and electronics purposes - including bonding, potting, encapsulating, coating, sealing, and staking. Higher up, in geostationary orbits where communications and weather satellites operate, particulate radiation (protons, electrons, and heavy ions) can cause problems. In low-Earth orbits, where space stations and most artificial satellites are deployed, there is highly reactive atomic oxygen (AO). They must also not outgas too much as the volatile by-products can degrade nearby optics and circuitry.ĭepending on where a spacecraft is headed, additional environmental factors may affect its design. ![]() Adhesives and epoxies used for space-borne equipment must withstand the temperature extremes and vacuum of outer space while maintaining their performance qualities. These factors impose a strict set of constraints on spacecraft equipment and materials. For some space-bound components, such as propulsion subsystems and certain experimental devices on the International Space Station, they must withstand exposure to cryogenic temperatures as low as 4°K. Instead, they must put up with extreme hot and cold temperatures, exotic forms of some common materials and elements, and high vacuum conditions. There is no atmosphere to protect them from radiation or provide a blanket of warmth. Satellites and spacecraft must survive and operate in an environment entirely different from that on Earth.
