Costly Ball to Guide Astronauts (Nov, 1961)

I wonder if this was part of the inspiration for Gravity Probe B, a satellite designed to measure how spacetime is warped by the earth. It had some seriously spherical gyroscopes:

At the time, the gyroscopes were the most nearly spherical objects ever made. Approximately the size of ping pong balls, they are perfectly round to within forty atoms (less than 10 nm). If one of these spheres were scaled to the size of the earth, the tallest mountains and deepest ocean trench would measure only 2.4 m (8 ft) high

Costly Ball to Guide Astronauts

A LITTLE metal ball, worth more than 30 times its weight in gold, is being tediously fashioned into shape as part of a guidance system that may help future astronauts find their way around the universe.

General Electric Co., Schenectady, N. Y., says the sphere of niobium will be a critical part of an inertial guidance system giving pinpoint accuracy to navigation of a jet, ocean liner, space ship, or submarine—largely as a result of suspending it in a vacuum and rotating it as the heart of a super-precise gyroscope.

Star Gazers in the Sky (Oct, 1956)

Star Gazers in the Sky

Vikng-Aerobee Operations Engineer White Sands Proving Ground

SOONER or later the question arises: what are we going to do when we finally get our rockets into outer space? Among the people who have answers ready are the astronomers. If you have ever built any of the telescopes featured in this magazine and then used them to look at the moon and the planets, you realize why. Through an earthbound telescope, the images swim, ripple and blur. No matter how good an observing spot you have chosen, you are always peering out through the Earth’s murky, turbulent atmosphere which distorts what you see and which also distorts the things scientific instruments such as the spectroscope see.

COMSAT: Communication in the Space Age (May, 1967)

“Seriously, though, the establishment of information grids, connected by relay satellite, has already been proposed. Some authorities think that in less than 10 years a student will be able to dial a local computer on his home telephone and program problems into it.”

That was actually a pretty good guess.

COMSAT: Communication in the Space Age

Not experimental, but commercial, instant worldwide information transmission by satellite
By RAY D. THROWER

In the 17th century, it took about 4 months for news of the New World to reach Europe. Now, with satellite communication, news whips around the globe in seconds. In less than 3 years, instant global communication will be a reality. Advanced communications equipment and the space-age vehicle, the Communications Satellite Corp. and its international partner, Intelsat, are all together responsible for that.

Instrumenting an Earth Satellite (Oct, 1958)

I googled Ronald Benrey, the kid who made the satellite to see what he went on to do. I was rather surprised when my own site came up in the results. Apparently Ronald went on to write for Popular Science and was the author of this excellent article about making your own laser.

Prize-winning Science Fair model reels off space secrets of the push of a button

WEBSTERS DEFINITION of Argus is incomplete. In Greek mythology, Argus has another connotation – it denotes the starry heavens. In all respects, it is a fitting name for a model satellite – “Argus I” -built by Ronald Michael Benrey and entered in the National Science Fair.

The satellite took second prize at the Fair and took first prize inn the Air Force’s Awards Program, as well as receiving other citations. While it doesn’t have the 100 eyes of the mythological Argus, it does have seven “eyes” – sensors designed to “see” such things as temperature, ultraviolet light and micrometeorites—as well as two “voices”—transmitters to relay the information to receivers.
