1e
1. What did some ancient cultures think about stars Why
2. What is carried on board by Voyager 1 Why
They believed that stars were from gods or other mysterious worlds.Because they did not have advanced technology or scientific knowledge to understand what stars really are.
A special record with sounds and pictures from Earth is carried on board.It shows who we are and where we are from, in case Voyager 1 is found by alien life.
3.What is the furthest trip that a human has travelled from Earth
Do you know any details about it
4. What do you think about the future of space exploration
The furthest that any human has gone is about 400,000 kilometres, around the far side of the moon. No human has travelled beyond the moon so far.
I think it is hopeful. Scientists believe that with cooperation, new technology will be developed. For example, astronauts might sleep during long journeys, or faster spacecraft will be built. One day we may reach the stars.
