Space ShuttCarries crew into space Reused Allows astronauts to fix things Space Station

large artificial satellite


people live and work on for long periods


 


The role of space shuttle


 


 go in to space and fix any thing that is broken


  The role of space station       to have people live and work for long periods of time   Space probe     spacecraft   scientific instrument that collect data   collect visual data with no life on bored 3 things that all space probes have each have power system to produce electricity


communication system to send and receive signals


scientific instrument to collect data and perform experiments


Advantages is that people dont have to risk there life by going up into space but if it brakes then they have to go up there ne ways and fix it

Space Exploration

The Science of Rockets

There are 3 stages.The first is called Atlas,witch uses soiled-fuel boosters and liquid-fuel engines to launch.The second stage is called Centaur,witch only uses liquid-fuel.The third stage is the Payload-the satellite or spacecraft that falls to earth and burns.

The Space Program

NASA is the National Aeronautics and Space Administration.There the people who came up with missions for the astronauts to do.Like project Mercury,where they tested if people could live in space.Apollo 13 is an air craft tested to see how it would work,it didn't turn out that good.

Exploring Space Today

The iss came up with little robots powered by solar cells.They go up with the astronauts and fly right next to them,using fans that control the way they move.

Using Space Science on Earth

NASA isn't getting enough money to build more stuff.they wont money so they can explore the unknown.Many people argue that the money can be spent better like for education or medical research.
