With the chemical symbol of “Au”, atomic number of “79”, and a melting point of 1064.43 degrees centigrade, Gold is a non-toxic, biologically friendly, and a metal of excellent electric conductivity known to Man from ancient times. Also thought to being closely connected to the ancient gods and Angels, Gold was platted into beautiful ornaments, and jewellery to please the wealthy, noble, and rulers. The ancient Egyptians used gold in the making of the Pyramids, and buried the Pharaohs with Gold. Many medieval Kings had their thrones, and armour built form the precious metal. As Man continued to evolve, he found out more ways to use gold to his advantage.
As unbelievable as it seems, gold is also utilised in Aerospace engineering. All the space vehicles produced, or launched by NASA has a quantity of gold within them. Because of its capability to conduct well, it is used in circuitry. Certain elements of all space vehicles have gold-coated polyester film on them. This film serves the rationale of reflecting infrared radiation, and preserves the temperature of the space vehicles as required. In the absences of this film, some components will infuse all the heat, immensely raising the temperature of the vehicle.
Devoid of gold, man would not have visited the moon. Gold, in the shape of sheets 0.15mm thick, are brought into play in space programmes, as a radiation safeguard. For the reason that gold is such an efficient reflector, it redirects the blazing heat of the sun.
Gold is essential to safe space travel, so its requirement has visibly grown, as the space industry has. For instance, more than 40.8 kilograms of gold was utilised in the building of the well-known US Columbia space shuttle, largely in brazing alloys, fuel cell manufacture, in addition to coated plastic films along with electrical contacts.
Gold is used in circuits that are built-in into the spacecrafts, as it is an outstanding conductor. In addition, several parts of spacecrafts are en suite with gold-coated polyester film that reflects infrared radiations, and assists with controlling the temperature within the vehicle. Without this, the vehicle would suck up too much heat, making it complicated to manoeuvre. Gold is in addition used as a lubricant among the assorted mechanical parts of the spacecraft. If any other lubricant were to be used, it would not have endured the radiation in space, and would have infused.
Gold is also used in making helmets put on by astronauts. An extremely thin layer of gold is electroplated within the visor, which averts the unsafe solar emission from inflowing, and mirrors it back. In this manner, it cares for the vision of the astronauts.
Gold is noteworthy in space travel. In view of the fact that space travel has amplified over the years, so has the stipulation for gold. It is used in approximately all space vehicles designed by NASA that are worth billions of dollars.
Even though gold is a costly element, its countless virtues make it useful for space vehicles. Had it not been used to buy gold, space voyage might not have been such a triumphant task, as it is in the present day.
