Start of a V-2 rocket in 1943 |
The exploration of space began some seventy
years ago, as a continuation of the Third Reich’s war effort to develop
ballistic missiles (the V-2 rocket) to bombard Britain and other places without
the need of airplanes.
At the end of World War II, the two new great
powers (the United States and the Soviet Union) recruited the scientists and
technicians who had carried out the German advances in that field, took them to
their respective countries and started programs of space exploration, whose
first objective was, of course, to obtain military advantages in the cold war
that had just begun. As a result of Operation Paperclip (the US
recruitment program), German scientists as important as Werner von Braun went
to work in the United States. An equivalent Soviet program (the Operation
Osoaviakhim) did the same with other German scientists, perhaps less
known, but equally efficient. With their help, both superpowers began a space
race that would last several decades.
Buzz Aldrin on the Moon |
In the following years the Russian advantage
widened: they were the first to reach the moon (with probe Luna-2,
September 12, 1959); photograph its hidden face (Luna-3,
October 4, 1959); reach Venus (probe Venera-1,
February 12, 1961); and put a man in space (Yuri Gagarin, April 12,
1961), something that NASA did not achieve until almost a year later (February
20, 1962). Finally, on June 19, 1963, the Russian probe Mars-1
was the first to reach Mars.
From that point, the situation
reversed. With the Apollo project, the United States took the
first place in the space race, putting the first man on the moon on July
20, 1969. The space race continued during the seventies with the first manned
space stations: Salyut-1 of the USSR (April 19, 1971) and
NASA’s Skylab (May 14, 1973).
Shortly afterwards, space collaboration began, with the first Soviet-American
joint mission (Apollo-Soyuz, July 17, 1975).
The nineties witnessed important
changes in the space programs. On the one hand, the disintegration of the
Soviet Union slowed the Russian impulse in the space race; on the other, NASA
halted manned space missions after the catastrophes of the Challenger Space Shuttle (January 28, 1986)
and the Columbia (January 16, 2003).
International Space Station |
In 1998 began the construction of
the International
Space Station (ISS), which from the beginning has been the result of international cooperation.
The placement of the first module, build by the Russians, took place on
November 20. The second, by NASA, on December 2. Since then, other countries
have collaborated in the maintenance of the station: the European space agency
(ESA), Japan and Canada. These five agencies agreed on a rotation system that
has kept a permanent crew at the station since November 2, 2000. Other
countries, such as Brazil and Italy, participate in particular ISS projects.
Today space exploration is
rapidly becoming an international project involving many countries. In the UN,
since 1959, there is a Committee for the Peaceful Uses of Outer Space (COPUOS), with currently
87 participant countries, which makes it one of the largest committees of the
UN General Assembly. Among its activities is the International Asteroid Warning
Network (IAWN), which searches for near-Earth objects (asteroids,
comets...) that could impact our planet in the near future, and designs
procedures to deviate them before impact, or to mitigate this type of disaster,
if it ever happens.
During his last years, Stephen
Hawking embraced a
pessimistic forecast about the future of humanity, which he saw threatened
by many dangers. As a solution, he proposed space exploration, starting with
the moon and the closest planets, and culminating, in 200 to 500 years, in a
program of one-way interstellar travel to colonize planets in different solar
systems. A program like this could only be taken to effect through
international cooperation. Would this be enough to stop the permanent
internecine struggles that impede the global concord of humanity? I leave this
question open.The same post in Spanish
