As we wait (impatiently) for the Hubble Space Telescope to return to action following its repair and updating by the STS-125 astronauts, it is easy to think about how Hubble has impacted society. Hubble has become a household name, bringing astronomy to the masses with its dramatic images of the cosmos. It has also changed our understanding of the universe. But there’s more ways that HST has impacted the world. Various technologies developed for the famous orbiting telescope have helped create or improve several different medical and and scientific tools. Here are five technology spinoffs from Hubble:
Micro-Endoscope for Medical Diagnosis:
The same technology that enhances HST’s images are now helping physicians perform micro-invasive arthroscopic surgery with more accurate diagnoses. Hubble technology helped improve the micro-endoscope, a surgical tool that enables surgeons to view what is happening inside the body on a screen, eliminating the need for a more invasive diagnostic procedure. This saves time, money and lessens the discomfort patients experience.
CCDs Enable Clearer, More Efficient Biopsies
Charge coupled devices (CCDs) used on the HST to convert light into electronic files—such as a distant star’s light directly into digital images—have been adapted to improve imaging and optics here on Earth. When scientists realized that existing CCD technology could not meet scientific requirements for the Hubble’s needs, NASA worked with an industry partner to develop a new, more advanced CCD. The industry partner then applied many of the NASA-driven enhancements to the manufacture of CCDs for digital mammography biopsy techniques, using CCDs to image breast tissue more clearly and efficiently. This allows doctors to analyze the tissue by stereotactic biopsy, which requires a needle rather than surgery.
Mirror Technology Increases Semiconductor Productivity, Performance
The semiconductor industry has benefitted from the ultra-precise mirror technology that gives the HST its full optical vision and telescopic power. This technological contribution helped improve optics manufacturing in microlithography—a method for printing tiny circuitry, such as in computer chips. The system uses molecular films that absorb and scatter incoming light, enabling superior precision and, consequently, higher productivity and better performance. This translates into better-made and potentially less costly computer circuitry and semiconductors.
