satellite into space yesterday.

The official Soviet news agency Tass said the
artificial moon, with a diameter of twenty-two inches and a weight of 184 pounds, was circling the earth once every hour and thirty-five minutes.

It said in its announcement that people now could see how "the new
socialist society" had turned the boldest dreams of mankind into reality.

"As a result of
intensive work by the research institutes and design bureaus, the first artificial earth satellite in the world has now been created."

The Soviet announcement said that as a result of the
tremendous speed at which the satellite was moving it would burn up as soon as it reached the denser layers of the atmosphere.

Military experts have said that the satellites would have no
practicable military application in the foreseeable future.

They said, however, that study of such satellites could provide valuable information that might be applied to flight studies for intercontinental

Their real significance would be in providing scientists with important new information concerning the nature of the sun,
cosmic radiation, solar radio interference and static-producing phenomena radiating from the north and south magnetic poles.

All this information would be of
inestimable value for those who are working on the problem of sending missiles and eventually men into the vast reaches of the solar system.
