The International Space Station (ISS) circles the globe
15.54 times every 24 hours with a crew of six astronauts. It’s a huge satellite
that races around the Earth at 17,500 miles per hour. The international
scientists who make up the crew travel in what’s called a low orbit that averages
an altitude of 248 miles.
Three American and three Russian astronauts left Earth for
the ISS in 2000 to become the first rotating group of scientists to live inside
the ISS. The largest structure ever put into space, the ISS covers an area
larger than a football field, including the end zones. It’s big enough to be
seen at night with the naked eye; it resembles a streaking star as it crosses
different parts of the globe. If it were on earth, the massive structure would
weigh 400 tons.
The main assembly started in 1998 and went on two years; improvements
have continued for the past 19 years. American shuttles and Russian rockets transported
pressured modules, external trusses and solar arrays that were assembled in
space like a giant erector set. The international mix of scientists who
comprise the changing crews of the ISS demonstrate co-operation and trust in
working together.
American and Russian governments paid the bulk of the costs
to assemble and begin operation of the ISS. The European Space Agency, the
Canadian Space Agency and the Japan Aerospace Exploration Agency contribute
money to help pay the $100 billion plus dollars spent so far to keep the ISS
floating above Earth.
While the two superpowers distrust each other on a political
platform, goodwill feelings are strong between Russia and the U.S. concerning
the ISS. Trust and co-operation between the U.S. and Russia (formerly the
Soviet Union) was at a high water mark in the late 1960’s into most of the 1970’s.
That time of mutual trust and co-operation became known as Détente (dey-tahnt).
That’s French and means a relaxing of tension, especially between nations, by
negotiations and agreement.
At the end of World War II, the Soviet Union and the United
States co-existed in a tumultuous time called the Cold War. Both countries
competed in manufacturing military buildup including nuclear weapons. Tensions
came to a head with the Cuban Missile Crisis in October 1962. It was a
dangerous time when the U.S. came close to war with the Soviets.
Détente became a popular idea as leaders and citizens of the
two countries realized that the stockpiling of weapons that could destroy Earth
several times over was useless and extremely expensive. Efforts to put
Americans and Soviets into space helped to overshadow the arms race.
The word Détente slowly left the lexicon of the two
countries by the time the Berlin Wall was knocked down in November 1989. That’s
when the Soviet Union and communism itself started coming apart.
Scientists who make up the crew of the ISS spend about six
months in the satellite before a new crew of astronauts replaces them. The ISS
provides a microgravity laboratory where crew members conduct experiments in
biology, physics, astronomy, meteorology and other fields. The ISS and future
space stations provide excellent opportunities to monitor weather patterns on
Earth. Manned exploration to other planets such as Mars would also by greatly helped
by such platforms as the ISS.
The commitment to keep funding the ISS for the next seven
years gives the two superpowers a chance to keep Détente working in space and
maybe, by example, make it spread among all nations.
