Results of tests at Goonhilly using the experimental communication satellites Telstar I and Telstar II
The first active communication satellite-Telstar I-was launched from Cape Canaveral by the National Aeronautics and Space Administration (NASA) on 10th July, 1962, and was later followed by Relay and Telstar II. Since the 10th July, 1962, many tests and demonstrations of television, multichannel telephony and telegraphy, facsimile and data transmission have been made via these experimental satellites. In addition, much data has been accumulated on microwave propagation, earth-station receiving system noise temperatures and satellite tracking accuracy. Such tests and data will be of considerable value for the planning and design of future operational communication-satellite systems.

Solar simulation testing of an earth satellite at Goddard Space Flight Center
The use of solar simulation to evaluate the thermal performance of a spacecraft is still relatively new and controversial. Reference 1 reports successful use of carbon arcs in testing the Telstar spacecraft. Additional information on the use of the carbon arc as a solar source should be useful in evaluating its effectiveness as a thermal design technique. At Goddard Space Flight Center carbon arcs have been used for achieving the solar simulation testing of spacecraft sized for the Delta and Scout boosters. This report presents data and experience from such testing, using the results from the flight backup Ariel II (UK-2/S-52) international satellite as an example.

Telstar I, volume 4
Volume IV of NASA Special Publication SP-32 was originally intended to contain only those papers published outside of the Bell System Technical Journal that were pertinent to the Telstar I project. However, since that time, the results of Telstar II have been reported to NASA by the Bell Telephone Laboratories. It was then decided that this report should also be included.
