“THE COMMUNICATIONS… WORKED BEAUTIFULLY”
A sailor and Collins Radio Company joined in a new effort last month. When Lt. Cmdr. M. Scott Carpenter circled the earth three times in his Aurora 7 Mercury space capsule, he kept in touch with Collins communication equipment identical to that used on three previous space flights.
Then upon re-entry into the earth’s atmosphere Carpenter – as expected – lost voice contact as a layer of ionized air built up around the capsule.
For a suspenseful 37 minutes the world waited with growing anxiety.
Then a Navy search craft reported receiving signals from the Sarah rescue beacon. The pulsating signals from the beacon led searchers to the site some 200 miles from the predicted impact area where the veteran Navy pilot was waiting in the waters of the Atlantic.
The message was relayed to an anxious world that Scott Carpenter was indeed alive – the world’s newest orbital pilot.
Earlier, everyone feared disaster had befallen the United States’ second manned orbital mission. Apparently, everyone was concerned but Scott Carpenter.
“Had I known you were worried, I would have been worried, too,” Scott said apologetically later. However, he indicated the problem was not one of failure of the communication equipment but his failure to communicate.
And Collins officials repeated once again the reliability of the company’s equipment in light of the newest success.
Indications at this writing are that the equipment continues to be functionally adequate and reliable and that no changes will be made when the next Mercury flight is made.
This does not mean that efforts to improve the communication system will cease.
“The more information we get from present equipment in future flights, the more we will have for analysis and continued improvement,” states Richard Valentine, Collins Project Mercury communication manager.
Much remains, for instance, to be learned about high frequency (HF) communication from orbital flights back to the ground.
“The Glenn and Carpenter flights proved, in effect, that HF voice transmissions can be made to any point in the world,” Valentine comments.
At one time over the continent of Africa, Carpenter’s voice was picked up half-way around the world by the capsule communicator in Hawaii. This was during a brief HF transmission.
“So that while Collins equipment has performed extremely well during prior flights,” Valentine added, “we feel that each new mission gives us more information to insure additional reliability and confidence in future flights in deep space.”
Carpenter himself supported this stand when, during a visit to the Collins facilities, he said: “The last astronaut to go might easily contribute more to mankind than any of the others. Most scientists working on a research project know what the ultimate objective is. In the case of Project Mercury, we won’t know exactly what we are after; however, we are convinced what we are doing is exceedingly important.”
