Gold is one of the most precious metals in the world, and has always been a symbol of wealth and luxury. It has been in use for centuries for different purposes such as jewellery, gold coins, dentistry, biology and manufacturing. It fetches a high price in the market, and the rate of gold is an important part of the economy of the world.
Besides the use of gold in manufacturing beautiful and attractive ornaments, it also has several other useful aspects. The multiple uses of this precious element make it extremely desirable not only amongst users but also for the betterment of the economy of the world. It can be converted in to wires or thin sheets. Moreover, it is a good conductor of heat and electricity. Thus, due to all these properties, it can be used for manufacturing electrical equipments.
Most of the people know about its usage in jewellery making, but science is far ahead in using this metal than these ornamental purposes. Due to all the characteristics of this metal, it is used in the manufacturing of spacecrafts. Discovery of gold has made possible the visit of man to the moon. Once the spacecraft is set off, it is nearly impossible to repair it or check it for lubrication issues. So, the use of gold in the manufacturing of space shuttle is a wise step. Gold can withstand a number of environmental and other harmful effects.
Due to the property of electricity conduction, it is used in the circuits of the spaceships. Moreover, it is also used for keeping the temperature of the spaceship stable. Temperature needs to be kept at a certain level so, gold is used along with the polyester covering. It initiates the reflection of infrared radiations thus, leading to the stability of the temperature.
Gold sheets with thickness of around 0.15 millimetres are used as a radiation sheet as they affectively reflect the light of the sun. Gold is also used as a lubricant between the various mechanical parts of the spacecraft. If any other lubricant was used, it would not have withstood the radiation in space and would have volatilized. Since gold is very malleable and ductile, it is easy to create very thin gold sheets that are used as lubricants between parts of metal.
Furthermore, it is used in the helmets of the space visitors. It is transformed into a thin electroplated sheet which is fitted in the visor for preventing the deadly solar rays. Thus, these rays are refracted back and the vision of the wearer remains safe.
The use of gold is very important in the manufacture of spacecrafts. The space travel has been increased over several years which also raised the value of gold to an enormous degree. Nearly all the spacecrafts designed by the NASA are made up of gold, used in several different forms. The US Columbia Space Shuttle has a record gold consumption in various forms including reflectors, conductors and soldering of alloys. Gold is a precious element, having innumerable characteristics, which made the space journey possible.
