War and science fiction inspired scientists and engineers like Konstantin Tsiolkovsky and Wernher von Braun to achieve flight beyond the atmosphere.

and "tag" a part. This certification guarantees that a part was repaired or overhauled to meet OEM specifications. Once a part is overhauled its value is determined from the supply and demand of the aerospace market.

Functional safety

Functional safety relates to a part of the general safety of a system or a piece of equipment. It implies that the system or equipment can be operated properly and without causing any danger, risk, damage or injury. Functional safety is crucial in the aerospace industry, which allows no compromises or negligence. In this respect, supervisory bodies, such as the

(EASA ), regulate the aerospace market with strict certification standards. This is meant to reach and ensure the highest possible level of safety. The standards AS 9100 in America, EN 9100 on the European market or JISQ 9100 in Asia particularly address the aerospace and aviation industry. These are standards applying to the functional safety of aerospace vehicles. Some companies are therefore specialized in the certification, inspection verification and testing of the vehicles and spare parts to ensure and attest compliance with the appropriate regulations.


Spinoffs

Spinoffs refer to any technology that is a direct result of coding or products created by NASA and redesigned for an alternate purpose. These technological advancements are one of the primary results of the aerospace industry, with $5.2 billion worth of revenue generated by spinoff technology, including computers and cellular devices. These spinoffs have applications in a variety of different fields including medicine, transportation, energy, consumer goods, public safety and more. NASA publishes an annual report called "Spinoffs", regarding many of the specific products and benefits to the aforementioned areas in an effort to highlight some of the ways funding is put to use. For example, in the most recent edition of this publication, "Spinoffs 2015", endoscopes are featured as one of the medical derivations of aerospace achievement. This device enables more precise and subsequently cost-effective neurosurgery by reducing complications through a minimally invasive procedure that abbreviates hospitalization. "These
