Communication Challenge
Communication in space
Kia Ora,
Today, I'm going to answer some of the questions about things that I've learnt about space/Mars.
Here are the questions:
What are some ways we communicate on Earth?
How do these forms of communication work, what do they rely on or use?
Why can nobody hear you shout in space?
Is radio communication instant? Why/Why not?
What does this mean for a space mission from Earth to Mars?
Could there be a way in the future to instantly end a message to someone on another planet?
Some ways that we use to communicate with each other are gadgets. Such as Phone/Telephone, Radio, Television, Internet/Social Media and etc. How the television works is:
There are three parts of the television inventions. The first one is the TV camera, it helps to turn a picture and a sound into a signal, there is also a TV transmitter, it sends the signal through the air. A TV receiver is set in your home, it captures the signal and it turns back to a picture and a sound.
When you talk or shout, you need air or water to travel your voice through, but in space there is no air, so sound has nothing to travel through. The sound wouldn’t even leave your mouth.
Radio is one way that you can communicate.
Which means that they should use code, people who travel to space usually use Hexadecimal code to communicate with each other.
It’s possible that there will be a way in the future to instantly send a message to someone on another planet, but NASA would have to find a way to do that.

Gold Rush
Gold is valuable because of it’s attractive looks and it’s rare, it’s mostly used in jewellery.
They dig to find gold underground but it can take a year finding gold. When it’s found, they use this machine to crush the rocks and it helps to separate the gold that is called stamper batteries.
They use trucks to help them dig underground and find gold.
The first person who discovered an amount of gold in New Zealand was by Charles Ring in 1852. He’s a Tasmanian who found gold at a driving creek near the town of Coromandel.
Years passed, there were more discoveries found around Golden Bay and Marlborough, Otago and West Coast. Some found nothing, but some found a huge amount of gold.
1867 was the first big discovery was near Thames. The gold was inside in a hard rock and they were expensive to mine.
In 1865, there was a new gold rush happening on the West Coast. Hundreds of Chinese miners were encouraged to come, and asked to rework the Otago goldfield. These miners were mostly from Southern China.
Most of the Chinese Miners didn’t speak English back then.
During the 1800's, there were many people from Guangzhou province who lived in poverty in Southern China. There was high unemployment, the place was over populated from the effects of the Opium Wars. One way to escape from poverty is to make the families pay for their brothers or sons to go overseas and work on the goldfield that was newly opened up. Many Chinese miners went to Australian, Californian, but most of them came to New Zealand.
They used to call New Zealand Sun Kum Shan or the new gold mountain.
