Space travel refer to spaceflight, flying into or through outer space. It is the use of astronomy and space technology to explore outer space. Space travel is just travelling in space using astronomy.

Purpose of space travel

The purpose of space travel include the following:

  1. Exploration: To be human is to be an explorer. It is part of who we are: since the first tribes left the African savanna and spread into Europe and Asia, we have had the need to explore the unknown. Now humans have visited or settled every corner of the globe. The instinct to explore is still active, but there are very few outlets. Some people seek out extreme or exotic places to satisfy this need, risking their lives to do so. Others look to the skies. It may be an old cliché, but Star Trek had it right: Space is the final frontier, and it calls to the explorer in all of us.
  2. New Technology: Space exploration brings together many smart people from many different fields and puts them to work on some very difficult problems. The result is not only fantastic scientific discoveries, but also many useful inventions.
  3. Answering The Big Questions: How did life begin? How did the universe begin? How was our world created? Are we alone? These questions and others have been asked by every generation since the dawn of time. That we can even ask them is a testament to the power of the human brain. Now, because we are smart enough and bold enough to explore the universe, we are finding the answers. In the words of Carl Sagan, “We are star stuff contemplating the stars.”
  4. Protecting and Understanding our World:
  • NASA’s health science division helps us understand the fantastically complex world that we live on.
  • Studying other worlds like Venus and Mars teaches us how special our planet is, and provides sobering examples of how the climate of planet can change.
  • NASA-funded research scans the skies for dangerous asteroids, and mission to asteroids teach us how we might be able to divert them from a collision course, should the need arise.
Benefits of space travel
  1. Taking action on climate change.
  2. Getting young people interested in science.
  3. Talking on cellular phones.
  4. Making scientific discoveries
  5. Creating jobs in technology
  6. Taking action on climate change.
Dangers to space travel
  1. No atmosphere, we need air to breathe.
  2. Space debris, danger from impact damage.
  3. Solar flares and radiation, danger from ionizing radiations

 

In our next class, we will be talking about Gravitation and Weightlessness.  We hope you enjoyed the class.
