Space Explorers 25 Extraordinary Stories Of Space Exploration And Adventure – Our first Earth orbiter was just two years old, taking off from the streets of Moscow a week before its historic launch. Her name was Laika. She was a terrier mix and a good dog in every way. His 1957 flight paved the way for space exploration when scientists did not know that spaceflight was fatal to living things.
Humans are explorers. Since the beginning of civilization, we have been lured to the horizon to find food or more space, to make a profit, or just to see what lies beyond those trees or mountains or oceans. Our ability to discover reached new heights – literally – in the last hundred years. Airplanes shortened distances, made travel easier, and showed us the Earth from a new perspective. In the middle of the last century, our aim was even higher.

Our first steps into space began as a race between the United States and the former Soviet Union, rivals in a global power struggle. Laika was put into orbit four years later by the first man, Soviet cosmonaut Yuri A. Gagarin. Having achieved Earth’s orbit, we turned our sights to the Moon. The United States landed two astronauts on its hard surface in 1969, and five more manned missions followed. The US National Aeronautics and Space Administration (NASA) began research to study the solar system. Human space stations began to shine in the sky. NASA developed reusable spacecraft – the Space Shuttle Orbiter – to carry astronauts and satellites into orbit. Space travel technology had advanced light years in just three decades. Gagarin had to parachute from his spacecraft after re-entry from orbit. The space shuttle leaves orbit at 16,465 mph (26,498 km/h) and glides to a stop on the runway without using engines.

Space travel is nothing like the movies. Getting from A to B requires complex calculations involving inertia and gravity — literally, rocket science — to “slingshot” from planet to planet (or moon) in the solar system. The 1970 Voyager mission took advantage of the rare orbits of Jupiter, Saturn, Uranus, and Neptune to cut the travel time by nearly 20 years. Space is also dangerous. More than 20 astronauts have died doing their jobs.
It hasn’t stopped people from signing up and signing up. NASA’s shuttle program has ended, but private companies are developing their own space programs. A company called Planetary Resources plans to send robotic astronauts to mine the Asteroid Belt for precious metals. Another company called SpaceX hopes to land solar astronauts on Mars in 20 years – the next human step into the solar system. NASA and other civilian companies are planning their own Mars missions.

Total Solar Eclipse During a total solar eclipse, the Moon comes completely between the Earth and the Sun to cast a shadow on the Earth.
Use your astronaut’s rocket booster to avoid obstacles and collect stars as you explore planets in our solar system.
