launch of an artificial satellite – designed and handcrafted by men – into space.
Occasioned by the anniversary, Romfilatelia, the specialized company in
editing and trading Romanian postage stamps introduces into circulation
the philatelic issue 50 years since the launching of the first artificial
Earth satellite – Sputnik 1.
On October 4, 1957, the Soviet Union inaugurated the competition for
Space conquest by launching Sputnik, the first artificial Earth satellite.
The artificial satellite, called Sputnik I – translated as “travel companion”
was launched from missile range at Kazakhstan. Sputnik I had a diameter
of 58 cm and a weight of around 84 kg. It made elliptical orbits around the
Earth at an altitude of 250 km, every one hour and 36 minutes.
Officially, the launch of Sputnik I was occasioned by manifestations
related the International Geophysical Year.
Visible through binoculars before sunrise and sunset, Sputnik I would
transmit radio wave information back to the Earth, strong enough to allow
reliable reception to radio amateur.
In January 1958, Sputnik I deviated from initial planned trajectory that
allowed it to stay in Earth orbit and entered the atmosphere disintegrating
following self ignition.
The launch of Sputnik I marked the moment when the great nations of
the world started the pursuit for the conquest of the extraterrestrial space,
of the Moon, research on Mars as well as other planets in our solar
system or even the ones further away.
