GEORGE CARRUTHERS INDUCTED INTO NATIONAL INVENTORS HALL OF FAME FOR INVENTING FAR ULTRAVIOLET ELECTROGRAPHIC CAMERA

Camera Used On Apollo 16 Mission To Photograph Earth From Moon’s Surface

¾ What weights 50 pounds, is gold-plated and only works on the moon? The Far Ultraviolet Camera and Spectrograph sent to the Moon in the Apollo 16 mission in 1972.

The camera was based on the far-ultraviolet electrographic camera that George Carruthers invented, giving scientists fresh, revealing images of Earth and space.

 George Carruthers was inducted into the Hall of Fame in recognition of his invention of the far ultraviolet electrographic camera. To commemorate the centennial of the Wright Brothers' first powered flight, the 31st annual induction of the National Inventors Hall of Fame  recognized pioneers in the aviation and aerospace industries. Carruthers' induction took place at the annual ceremony in May 3, 2003 at the Inventor's Hall of Fame in Akron, Ohio.

With the Naval Research Laboratory since 1964, Carruthers has been a driving force in the use of ultraviolet astronomy to learn more about the universe. His most well-known contribution was in developing the Apollo 16 far ultraviolet camera and spectrograph, which was designed specifically for use on the moon’s surface to record radiation from the upper half of the ultraviolet (UV) spectrum. "What we had proposed to do was set up a camera on the surface of the moon to observe the Earth and study its hydrogen atmosphere, which extends out to many thousands of miles," explains Carruthers. "Even the space station and the shuttle can’t get far enough away to really study the higher atmosphere."

A pioneer in ultraviolet astronomy, Carruthers’ invention was first used in sounding rocket flights in 1966, and made the first detection of molecular hydrogen in deep space during a 1970 flight. The camera used in the Apollo 16 mission produced about 200 photos revealing new features of Earth’s far-outer atmosphere, as well as deep-space objects from the perspective of the lunar surface.

"People sort of expected to see what we saw, but even so, just having the first pictures that actually verified that, was very exciting," says Carruthers. It also produced new far ultraviolet images of stars, nebulas, and galaxies, as well as new views of the Earth.

Although the camera itself was left behind, a second version was used aboard the final Skylab flight in 1973 to obtain images of Comet Kohoutek. Carruthers has also been involved in numerous sounding rocket and space shuttle flights utilizing his cameras, including far-UV studies of stars and nebulas, Comets Halley and West and the Earth’s upper atmosphere. His most recent experiment was carried out on the unmanned DoD ARGOS satellite mission, launched in 1999.

"One of the things that makes it very exciting and interesting is that in the early days of the space program almost every flight was something that was breaking new ground – especially in the astronomy area where we were previously limited to telescopes from the ground," says Carruthers.

Even at a young age Carruthers had an affinity towards astronomy and science, building his own telescopes and spending time at local science museums. In high school, Carruthers read about the early space exploits of the Naval Research Laboratory, so as a graduate student, he jumped at the chance to receive a postdoctoral appointment with the organization. He received his Bachelor of Science in aeronautical engineering, Masters in nuclear engineering and doctorate in aeronautical and astronautical engineering, from the University of Illinois.

Carruthers has received numerous awards, including Black Engineer of the Year in 1987, the Arthur S. Fleming Award in 1971, the Exceptional Achievement Scientific Award from NASA in 1972 and the Warner Prize from the American Astronomical Society in 1973. Carruthers was also a member of two independent review committees for the Hubble Space Telescope Project.

Carruthers was born in 1939 in Cincinnati, Ohio, but moved at age 12 to the south side of Chicago, Illinois. As a senior astrophysicist and head of the ultraviolet measurements group. Carruthers is also active in education and public outreach, including promoting science and technology among young African Americans, editing and co-authoring several publications, teaching, and co-producing a series of videos on Earth and space for high school students.  He is the editor of the National Technical Association Journal and newsletter.
