What Materials Are Used In Space?

All materials are subjected to extreme forces in orbit, enabling only the most sturdy items to withstand it.

Inspection processes for space materials are critical to guarantee that the equipment that utilizes them will last in the harshest circumstances known to humankind, with no repair facility at hand.

Lacking testing attempts to place satellites into space are futile if the equipment malfunctions in the warmth of the atmosphere or the coldness of space. A thorough examination is much more than a set of steps. It should be a fundamental component of assuring the survival of aerospace products.

To withstand the harshness of space, several ships must be designed. Satellites, rockets, and even NASA’s space mobility units (EMU) require parts that guard against collisions, stress, radiation, and temperature fluctuations.

Because they all have to resist similar conditions with just the levels changing, testing for durability for many different types of spaceship conflicts. Specific materials must be tested on the ship, and the mechanisms must also be examined.

Batteries, fuel cells, solar energy, telecommunication networks, electronic parts, and antennae are just a few of the satellite elements we evaluate to verify they will work properly after the device reaches space.

As well as satellites, the gear onboard them, such as communication systems and cameras, must be durable enough to withstand the same circumstances. Space simulations can assist check that these gadgets are adequately protected from the extreme circumstances they would encounter while in use.

While guaranteeing that the general spaceship and its gear will hold up throughout usage, engineers must first ensure that the materials selected will not break down when exposed to the conditions of space.


Kevlar is more commonly linked with its application in bulletproof clothing for the military and law enforcement. This substance has a number of characteristics that make it perfect for use in spacecraft. It is strong enough to withstand bullets, making it ideal for surviving meteor and space trash hits.

Furthermore, Kevlar is lightweight in comparison to its toughness. It can also withstand severe temperatures without causing structural damage or changing shape.


Aluminum is another frequent component used in spacecraft. Though aluminum may not have the strength required for interstellar use on its own, when mixed with the other metals to form an alloy, its strength rises while preserving its distinctive lightweight.

The International Space Station employs aluminum alloy for its windshield shutters to avoid junk from harming the glass since it performed so well in mechanical testing.

Reinforced Carbon-Carbon Composite

NASA employed a reinforced carbon-carbon composite for the tip of the spacecraft that was exposed to temperatures of more than 1,260 degrees Celsius (2,300 degrees Fahrenheit) (RCC). This combination was employed in other places of the space shuttle that endured comparable high temperatures.

The advantage of RCC is its capacity to emit both direct and indirect heat when heated. The heat from the spacecraft's neighboring surfaces moved to the RCC-covered sections, where the RCC would release the heat, assisting the shuttle in cooling down, similar to how a radiator indirectly cools a car engine.

When the engineers put silicon carbide covering at high temperatures during the RCC manufacturing process, cracks formed. The fractures, though, close as the temperature all around the spacecraft rises. The shifting structure of the sample at different temperatures iterates how important checking the contents are.

Reusable Surface Insulation

The high-temperature replaceable surface insulation (HRSI) includes a black borosilicate glass surface, allowing this dark surface to withstand the same extreme temps as the nose cone.

The spacecraft's white sections contain low-temperature reusable surface insulation (LRSI) and could only endure temperatures as high as 649 degrees Celsius (1,200 degrees Fahrenheit). The white color provides for better temperature management within the spacecraft, where the crew operated.


Silica fabric was used to plug holes on the space shuttle due to moving equipment, such as the landing gear or the storage bay. The RCC nose, which used sodium silicate to repair fractures generated during the surface treatment, was another section of the spacecraft that is using silica in its various forms.

NASA chose silica panels for the spacecraft's lower temperature zones, whereas the HRSI components of the ship were coated with borosilicate glass.

Can Plastic Survive In Space?

Yes. Plastics play an important role in spaceflight, and new plastic substances are continually being developed to withstand the harsh conditions of space.

Consider the exterior temperature of the International Space Station: negative 157 degrees Celsius to + 177 degrees Celsius. Human survival in this atmosphere necessitates the usage of very specific suits made of cutting-edge plastic materials. 

Spacecraft must also be "dressed" to withstand fluctuations in changes in temperature, space radiation, and lightning storms. They are able to withstand these brutal environments in space thanks to plastic barriers and insulating materials.

Can You Use Wood In Space?

Technically, yes. It’s entirely possible to use wood in space. To begin with, wood could not rot in space because there would be no air or oxygen, which several degrading bacteria would most likely utilize. Worse yet, there would be no moisture at all.

Any liquid in the timber would rapidly boil, leaving the wood bone dry, that's if it was still in one piece. Even microorganisms that could have survived only on wood will rapidly lose a huge amount of their capacity to metabolize in the absence of water or air.

Wood, on the other hand, would be a terrible construction material. For starters, it's not airtight. Building pressurized buildings would be difficult since the air would flow through the wood.

Even if you are not interested in constructing pressurized structures, you would not utilize wood.

For the level of assistance it gives, wood is quite hefty. Because weight is a factor in space launch activities, an aluminum construction would be far more cost-effective. Even if you didn't really care about it, the timber would most likely not react well to weather changes.
