First steps means how men stared to exploring space using satellites. There are five satellites to be first at something. In 1957 sputnik 1 was the first satellite to orbit Earth and send back radio signals. In1957 sputnik 2 was the first satellite to send a dog into space. In 1959 explorer 6 was the first satellite to send back TV pictures of Earth. In 1960 tiros1 was the first satellite to send back weather information to Earth. In 1960 echo 1 was the first satellite to relay voice and TV signals from one point on Earth to another. Laika the dog was the first creature in space.
On April 12,1961 ,soviet astronaut Yuri Gagarin blasted off in his spacecraft . This mission was the first to send a human being in to space. He spent almost two hours out there, orbiting earth one time. The next year astronaut John Glenn blasted off in the spacecraft Friendship 7 and orbited Earth three times.
Apollo 7 carried three astronauts into space. They tested the spaceship that would soon take men to the moon. The lunar module was a special spacecraft. It was built for one purpose only. After exploring the moon, the two astronauts would blast off from the moon’s surface in the lunar module.
The United states made it to the moon first. Scientists hoped to build a space station. Their answer was the space shuttle. This was the first space craft ever built that could be used more than one time.
But many has unmanned space crafts have explored the planets of our solar system and beyond. Mariner explored the atmosphere of mars. Most recently, the Cassini - Huygens spacecraft sent back pictures of the surface of Saturn largest moon, Titan. Many people on earth explore the night sky with a telescope.
We’ve been exploring space for almost 50 years. We’ve learned about space from manned space missions, satellites, unmanned probes, and telescopes.
Space travel is dangerous and expensive. Is it worth it? I think if it is a good mission then yes.Was laika’s death a waste? I do not think so.Would you be a good astronaut ? I would be a good astronaut.If you could explore space or the deep sea which would you explore and why?The deep sea because it seems more beautiful.
