Scientists
in Germany in the 1940s had developed the first guided missiles, using
technology that might make it possible for people to travel into space. This
prompted the US and the Soviet Union to embark on a ‘space race’.
In 1957, the Soviet Union launched Sputnik 1, the first
artificial Earth satellite. It took 96 minutes to orbit the Earth. In the
following year, the US launched its first satellite, Explorer 1. Both countries
spent vast amounts of money on space science.
The first person to orbit the Earth was Yuri Gagarin of
the Soviet Union in 1961. The US set out to land a man on the Moon by 1970.
This ambition was achieved when Neil Armstrong became the first person to walk
on the Moon in 1969.
During the 1970s, Britain, China, France, India and
Japan sent small spacecraft into orbit. Many of these were satellites, used for
weather forecasting and for communications. The US and the Soviet Union sent
craft deeper into space, sending back pictures and scientific information from
the planets.
Since the 1990s and the easing of the Cold War, US and
Russian scientists have worked together on space projects such as building the
International Space Station.
