I can identify key technological advancements that helped in making our knowledge of space expand. My research will show the past, but I will also predict what future advancements may stretch our limits even more.
The telescope was introduced to astronomy in 1609 by an Italian scientist, Galileo Galilei
Galileo’s telescope was similar to a pair of opera glasses, it used glass lenses to magnify objects
However, his design provided limited magnification… He could only see a quarter of the moon’s surface without having to reposition his telescope
In 1704, Sir Isaac Newton released his new design of the telescope. He used a curved mirror instead of glass lenses. That way it could gather light and reflect it back to a point of focus.
The telescope that Newton designed led to magnifying objects a million times beyond what could ever be discovered with a lense.
For many years, humans have been putting satellites into orbit around Earth
The many satellites that have been put into orbit provide communications, broadcast television and radio signals, and help scientists predict weather.
There are more than 8,000 artificial objects orbiting space and more than 2,500 of these are satellites, alive or dead.
The Space Race
The Space Race grew after World War ll, the Cold War pushed through the space race. The United States and Soviet Union raced to achieve dominants of space technology and exploration.
The Space Race Timeline
October 4th, 1957- Soviet Union launched Sputnik 1- the first artificial satellite. ICBM- Intercontinental Ballistic Missile
November 3, 1957- The Soviet Union launches the first animal in space
January 31, 1958- The first American satellite Explorer 1 was launched into space
April 12, 1961- Yuri Gagarin is the first man in space (Soviet Union)
May 5, 1961- Alan Shepard was the first American in space
May 25, 1961- JFK made a famous speech to Congress- America will have a man walk on the moon by the end of the decade
March 18, 1965- The Soviet Union had a man walk in space
June 3, 1965- Ed White was the first American to walk in space
July 20, 1969- Neal Armstrong and Buzz Aldrin walked on the moon(Michael Collins)
After the war ended, the Russians and United States decided to form a space station together. Both countries had great technologies in the Space Race and when they formed together, their ideas together made even greater technologies.
The world will be making new developments in space. For the United States, the goals are to create a colony based in orbit, military, and build new spacecraft.
The United States is now working on a tiny colony in orbit, the space station Freedom. Freedom is expected to live for three decades, orbiting around Earth every ninety minutes at a distance of 220 miles. The United States, Russia, Japan, Canada, and ESA (European Space Agency) will help the colony by providing smaller laboratory units. The goal of NASA is to conduct experiments to test the effect of microgravity on many different materials and living things.
I think there are many new space technologies coming our way soon and way in the future. I think these technologies will help us uncover the many mysteries about space. I believe once the mysteries are conquered, the amount of technological advancements will be huge and deeply affect the lives of people!
