Communication In Space

Hello everyone, this blog post is about what we did in hurumanu 3 which is science. In Science, we are learning about communication in space. The teachers provided some questions for us to answer, its also space related. 

What are some ways we communicate on Earth? Pick 3

Telephone/Mobile phone - We can use telephone to communicate people in online, by calling or chatting.

How do these forms of communication work, what do they rely on or use?

If they use telephone, they would actually rely on the electrical signal. Because if you don't receive the signal, you won't be able to call with someone you want to call with.

Why can nobody hear you shout at space?

Well eventually, no one can hear you if you shout in space. It's because, Mars and Earth has a long distance between each other.

Is radio communication instant? Why/Why not?

Radio communication can be also instant or sometimes not, because it depends if the signal sends fast.

What does this mean for space missions from Earth to Mars?

Well communication in space is a bit hard, because if someone is in Earth and they tried to communicate with an astronaut in space using their device. That would actually take a long time for the astronauts to get the signal from the earth. That would take months.

Thank you for reading this post about communication in space, bye.
