What is out there?

Is there an end?

Has the concept of space been fabricated in a Hollywood studio?

Why do we want to explore space?

But before we make the long journey into space……

The light-year (ly) is a unit used to measure distances to starts and other distant bodies.

1 ly is equal to 10X1015 meters… that is ~6 trillion miles (6,000,000,000,000) 12 zeros!!!

…CAN WE SURVIVE OUT THERE?Is there water?

Is there food?

Is the temperature suitable?

Is there anywhere for the spacecraft to land/take off from?

Are there other life forms which may exist?

These questions can be answered by unmanned spacecraft's which survey distant planets
