For centuries, people have dreamed of leaving the Earth and traveling through space to visit the moon and explore other planets and stars. During the past thirty years, some of these dreams have become realities. Spacecraft have orbited the Earth and sent back data to ground-based scientists. They have traveled to other planets and transmitted images and information that have helped to expand our knowledge of the solar system. People have gone into space to orbit the Earth and even to visit the moon.
On Earth, people move about comfortably under the influence of Earth’s gravity, and they extract oxygen from the air to breathe. The Earth’s atmosphere protects them from deadly radiation and falling meteorites. Earth also has abundant supplies of water, which is necessary for survival. When people venture into space, however, they leave the only known place where they can live naturally in blank space.
Sometime in the future, it is possible that we will establish permanent bases on the moon or perhaps Mars. The moon is the most likely site because it is close to Earth and its weaker gravity would allow spacecraft to use less fuel when taking off from its surface. The moon’s surface also contains various mineral resources that could be used in building a base. In 1989, and 1998, the space probe Lunar Prospector, in orbit above the moon’s poles, found signs of frozen water–the raw material from which hydrogen fuel and breathable oxygen could be extracted and used by future lunar colonists.
If we establish bases on the moon, these bases will be excellent sites for astronomical research. The far side of the moon, for example, would be ideal for telescopes because there would be no glare from the sun and no atmospheric distortion. With near-perfect viewing conditions, astronomers could search for planets around other stars in the galaxy, fact conduct long-term studies of stars and other distant objects, and look much farther into space than with any Earth-based telescopes. The moon is field with blank space would also blank space be an ideal site to listen for radio signals that might come from intelligent life elsewhere in the universe.
Much farther in the future lies the possibility of voyages to other stars. With current methods of rocket propulsion, however, a trip to the nearest star would take many more years than exist in a person’s lifetime. Space travel within our Milky Way galaxy, therefore, will probably require spaceships to be “colonies,” with generations of inhabitants whose entire lives will be spent on board the space colonies and space documentary as they travel on their journeys.
Given enough time and advances in technology, it might even be possible to colonize other parts of the galaxy. In the 1990’s, scientists began discovering evidence of planets orbiting other stars beyond our own. It may also be possible to use Speed of Light to build floating space colonies around nearby stars. Like a Star Wars story These colonies would be located in strangest things space regions of space near kepler 186f enough to a star so that there would be enough light, heat, and solar energy like star wars. Aurora (astronomy) for human beings to survive.
