Ukraine Celebrates 50 Years in Space

Ukraine recently celebrated the 50th anniversary of its
first satellite launch into space. On March 16, 1962, the Cosmos-2 rocket
lifted off with the Cosmos-1 satellite aboard. Both the rocket and the
spacecraft were developed by the Ukrainian-based Special Design Office 586 (OKB
586), now known as Yuzhnoye SDO.
In addition to the Cosmos family of rockets, Yuzhnoye’s
other launch vehicles include the Zenit rockets flown by Land Launch and Sea
Launch, the Dnepr ballistic missiles used to launch small satellites, the
Cyclone-4 boosters set to make begin flights out of Alcantara in Brazil next
year, and the first stage tanks and structure for Orbital Sciences
Corporation’s new Antares rocket that will lift off from Virginia later this
year. The company also provides an upper stage for Europe’s new Vega launcher.
Ukraine’s contributions to space are often overlooked,
and this anniversary went largely unnoticed outside of that nation. So, I
thought it would be nice to give the Ukrainians their due. I found an account
of the launch prepared by the good folks at the Yuzhnoye press office. It
begins after the break.
50 Years in Space: How it All Began
The 16th of March is a remarkable date in Ukraine’s calendar of
outstanding events in space. Exactly 50 years ago in 1962, the first
Dnepropetrovsk satellite DS-2 was launched by a new launch vehicle, named
Cosmos (the second one in USSR after famous R-7 rocket, designed by S.P.
Korolev).
Launch Vehicle
First works on development of launch vehicle intended for launch of
small satellites were performed as far back as 1956 in Special Design Office
586 (OKB 586), at present known as Yuzhnoye SDO, (as an alternative option of
OKB-1 project, directed by S.P. Korolev) however, after successful launch of
the world’s first artificial Earth satellite onboard R-7 rocket, temporarily
there was no need for one more space launch vehicle.
Later this idea was reconsidered, since R-7 rocket was too expensive and
difficult to operate for launches of relatively small artificial Earth
satellites. The preliminary design of a new two-stage launch vehicle on the
basis of Dnepropetrovsk military ballistic missile 8K63, R-12 is the same
missile (the most mass produced ballistic missile at that time) was finished in
April 1960, governmental regulation for its development was signed in August
1960. Owing to competent designing and great enthusiasm the first rocket was
already shipped to launch site in summer 1961 – less than a year since the
regulation was issued.
In order to save time and costs the first stage was built on the basis
of R-12 missile, modified for installation of second stage, and part of first
stage’s design concepts was implemented in second stage. The RD-119 engine
developed by OKB-456 (V.P. Glushko) and powered by unsymmetrical
dimethylhydrazine was accepted for the second stage.
Successful Launch
The successful launch of 63C1 launch vehicle from a silo launcher of
Mayak-2 launch complex was performed on March 16, 1962 at Kapustin Yar
spaceport and first acting DS-2 spacecraft, developed by OKB-586, was injected
into orbit. This event has opened a new phase in OKB-586 development that has
also shown its capabilities in the field of rocket and space technology
development and peaceful space exploration.
The DS-2 satellite was designed and manufactured in record time – about
two months.
The satellite with mass of 47 kg, represented a spherical container
inside which the Mayak double-frequency transmitter, intended for ionosphere
and Earth atmosphere sounding using radio-frequency emission, and accumulator
battery were installed and two couples of ribbon and rod antennas were located
outside.
Afterword
The DS-2 spacecraft, named in mass media Cosmos-1, has become the first
satellite in Cosmos family of different purpose spacecrafts. Then followed the
development and launch of a series of scientific spacecrafts (research
satellites, small unified satellites, automatic unified orbital station –
AUOS), defense satellites (positioning, calibration, radar surveillance) and
natural resources monitoring satellites (Earth remote sensing satellites).
The Cosmos launch vehicle was operated at the following spaceports:
Kapustin Yar (1962-1964 – Mayak-2 silo launch complex, 1964-1973 – Dviana
reequipped silo launch complex) and Plesetsk (1967-1977 – Raduga launch
complex).
The total number of Cosmos launch-vehicles launches is 165, out of them
143 were successful.
The way into space, paved by Cosmos LV, continued with other
launch-vehicles developed by Yuzhnoye SDO: Cosmos-2, Cyclone-2, Cyclone-3,
Dnepr, Zenit-2, Zenit-3SL, Zenit-2SLB, Zenit-3SLB. The Cyclone-4 launch vehicle
is being prepared for the first launch from Alcantara spaceport (Brazil).
