2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. We’ve been exploring space for almost 50
years.
We’ve learned about space from manned space
missions, satellites, unmanned probes, and
telescopes.
8. 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.
