For example, it is widely believed that Teflon was invented by NASA; in reality, it was invented in 1938, but used by NASA in its space programmes. Not so commonly known is that NASA developed what turned into the smartphone camera as a means of capturing images. And, no, neither did NASA invent Velcro.
Now, the organisation is poised on the brink of another major development where it is looking to create an integrated photonics modem. This device will bring together a range of items in order to simplify optical system design, reduce power consumption and improve reliability.
One of the applications which NASA will test is laser based communications. Currently, it communicates using RF technology, but optical communications will boost data rates and bandwidth. But other applications are envisaged in medical imaging and advanced manufacturing.
The photonics chip is likely to be tested on the International Space Station in 2020, after which, the technology will be made available to industry.
Commercialising such research is often a challenge in itself. While technology developed for space should be made available to all, the case for that developed by military organisations is less clear cut. But what was once held tightly is beginning to filter into general availability.
