Half-Ton Satellite Circling Earth
Dog Inside Reported In "Good Condition"
ORBIT 900 MILES IN OUTER SPACE
The second Soviet artificial satellite, which carries a dog in a pressurized
container, has been circling the earth every hour and 42 minutes since it was
launched early yesterday morning-to the surprise of western scientists.
It weighs half a ton, more than six times as much as the first Soviet satellite
which was launched just a month earlier. United States Army scientists estimate
that a rocket weighing about 500 tons must have been used to launch it. The dog,
which is supplied with artificial food, had previously made training flights in
rockets.
Moscow radio said that by 5 p.m. yesterday the satellite had completed seven
circuits of the earth. The dog had been behaving quietly, and its general
condition was satisfactory.
RETURN JOURNEY
According to Professor Blagonravov, one of the designers of the first satellite,
its life is not in danger, and an unnamed Soviet scientist was reported in
Germany to have said that it was hoped that it would return to earth.
A Reuter report from Hamburg said that the scientist had said to a reporter of
the western German news agency D.P.A. that the dog's departure from the
satellite on its return journey to earth would be announced by a wireless
signal. From two to three hours would elapse between this signal and the dog's
expected landing. During this period it would be possible to calculate where the
landing-place would be.
"Braking equipment" built into the dog-container would prevent the latter from
becoming a miniature satellite which would itself circle the earth. The dog
would be pushed out of the container a few thousand yards above the earth,
because it would not survive a "jump" from a greater height. It would then float
down by parachute.
930 MILES HIGH
Moscow radio said last night that the dog was a Husky (laika in Russian).
This satellite is dedicated to the fortieth anniversary of the October
revolution, which falls on Thursday, and is part of the Soviet programme for the
International Geophysical Year. According to Professor Blagonravov, it is likely
to stay up "for a long time." The greatest height of its orbit is 930 miles,
more than 300 miles higher than that of the first satellite. The speed of the
second satellite is given as about 18,000 miles an hour.
PROCEEDING NORMALLY
The total weight of this apparatus, the experimental animal, and the power
sources amounted to 508.3 kilograms, and the satellite, according to
observations, had been given an orbital velocity of about 8,000 metres a second.
The agency added that, according to calculations which were being verified by
observation, the maximum distance of the satellite from the surface of the earth
exceeded 1,500 kilometres; a complete circuit took about one hour 42 minutes;
and the angle of inclination of the orbit to the plane of the equator was about
65 deg.
According to information received from the satellite, the scientific instruments
and control of the life processes in the animal were proceeding normally.
Signals from the satellite on 20.005 kilocycles were in the form of telegraph
beats lasting about 0.3 sec. with a pause of similar duration. The transmission
on 40.002 kilocycles was continual.
UNFATHOMED PROCESSES
The news of the launching of the second satellite was broadcast from Moscow at 6
a.m. and 10 minutes later the first recording of its transit was made at the
Mullard Radio Observatory, Cambridge, where the apparatus had been left running
in case the first satellite resumed transmission.
It was heard again at 7.54 a.m., 9.36 a.m., and 11.26 a.m. It was expected,
however, to take at least 24 hours before they would be able to get a clear
indication of the orbit.
OPPOSITE DIRECTION
A spokesman said that findings so far were consistent with the satellite's
having been launched in the opposite direction from the first-south rather than
north.
Professor A.C.B. Lovell, in charge of the Radio Astronomy station at Jodrell
Bank, said: "The problem is now one of numbers. We have two rockets and two
satellites, but only one radio telescope. The difficulty is that we are still
rather heavily engaged on tracing the old satellite and rocket."
Of the second satellite he said: "I can only say it is a very dramatic and
spectacular demonstration of Russian achievement in science and technology."
While British scientists were applauding Russian scientific prowess,
animal-lovers were up in arms at the fate of the dog hurtling round the earth in
a hermetically sealed container. Not even the statement that the animal had been
provided with food and water allayed their alarm, or that arrangement had been
made for getting it back to earth.
Almost before the B.B.C. announcer had finished the Sunday morning news bulletin
the London headquarters of the R.S.P.C.A. was receiving telephone calls of
protest from the public. A spokesman said that the society had protested to the
Soviet Embassy in London when the idea of using an animal for this purpose was
first put forward.
Officers of the National Canine Defence League are calling at the Russian
Embassy this morning to lodge a protest. The league calls for a minute's silence
daily on behalf of the dog in the satellite.
U.S. TALK OF NEW "PEARL HARBOUR"
WAVE OF ALARM
WASHINGTON, NOV. 3.-This time there is no mistaking the wave of alarm created in
America by the launching of Russia's second sputnik, which has exploded any
lingering disposition to scoff at the first satellite, still circling in its
orbit, as a "celestial bauble"-the words of Mr. Sherman Adams of the White
House.
All the implications of size, height and propulsion, no less than the fact that
the first living creature has been projected into outer space, must surely serve
to destroy the last shreds of complacency that seemed to settle over the country
again.
COMPELLING TRUTH
The compelling truth is that in scope and conception-and there is certainly now
no tendency to question Russian claims-this second venture into space far
exceeds any known American satellite project for the International Geophysical
Year.
President Eisenhower, who plans to embark on a personal crusade against doubt
and scepticism, may now be at a loss for convincing evidence in exhorting the
country to renewed confidence in its scientific prowess.
The announcement that the second sputnik was launched and circling in an orbit
almost twice as high as that of the first satellite flared from the later
editions of the Sunday newspapers, and all day there has been a stream of
comment and speculation, mostly of a scientific nature, from the wireless
networks.
Initial political reaction was confined to the view of one or two senators that
the country has had something like a new "Pearl Harbour"; this, they urged, was
the time to "get going."
There is less surprise at the launching of a second sputnik than amazement at
its size and weight-and the weight of the first had already been met with a good
deal of incredulity.
One expert sees no reason to doubt that the Russians could send a rocket to the
moon within the next week, and he and others concede that they have indeed
demonstrated their ability to launch an inter-continental ballistic missile. In
the opinion of Dr. Whipple, head of the Smithsonian Observatory at Cambridge,
Massachusetts, the new sputnik is "six times as great a scientific achievement
as the first," being six times heavier, and he suggested that a new type of fuel
might have been used to lift such a huge body.
GAIN TO KNOWLEDGE
A vast gain to scientific knowledge is seen in Russian assurances that all the
data received will be made available to other countries.
Technicians at the Massachusetts Institute of Technology claimed that they could
hear the dog breathing in the background of the signals they monitored, but much
less feeling than in Britain seems to have been roused here over this use of an
animal; American commentators have even observed that British opinion would be
less concerned had a human being thus been sent into outer space.
It is known that a dog was selected because of its aptitude for training; a dog
can be induced to feed itself or even to transmit signals in response to audible
devices; and it is noted that Professor Blagonravov said here that he had fired
his own dog about 100 miles inside a rocket, and that it was afterwards
recovered alive.
