(BQ) Looking back at the creation and accelerated development of the early U.S. and former-Soviet "space race," ebook Scientific American: Great Moments in Space Exploration profiles the intrepid American astronauts and Russian cosmonauts who boldly ventured where none had gone before. It also offers current facts on the most recent developments in space technology, including those involving international cooperation among countries.
Humans have been exploring their world for thousands
of years. People love to discover and learn about new
places. Some of today's explorers are making exciting
new discoveries in space.
Many objects are found in the universe. These
include asteroids, planets, moons, comets, and stars.
Astronomers are scientists who study the objects in
space. People who travel to space to learn about it
are called astronauts.
We are privileged to be living in one of the greatest eras of exploration that humankind has
ever undertaken. Our current Age of Space grew out of the dark struggles of World War II
when large rockets were developed as agents of mass murder. The subsequent Cold War
rivalry between the United States and Soviet Union pushed rocket capabilities to the point
that it became possible to send vehicles into Earth orbit and beyond (even though the stated
aim was to send missiles carrying nuclear weapons over mere continental distances). The
Russians put the first human into Earth orbit.
