There has been a lot of excitement about the Juno probe this week, but what is it and what is its mission?
What is Juno?
Juno is a spacecraft designed and operated by NASA, the US space agency. It was launched from Cape Canaveral on the 5th August 2011 and has taken almost 5 years to travel the 716 million kilometres to Jupiter, the largest planet in our solar system. Juno is 3.5 metres in height, and when its solar arrays are extended it’s more than 20 metres across. These arrays are covered in more than 18,500 solar cells, which allows Juno to operate even when it’s at such a great distance from the Sun.

Why is it called Juno?
In Roman mythology Juno was the Queen of the gods. She was married to the king, Jupiter, who wasn’t always well-behaved. Juno had to peer through the clouds to discover what he was up to; the spacecraft is called Juno because it will be looking beneath the clouds that cover the surface of the planet Jupiter.
Aboard the Juno craft are 3 models of Lego minifigures: Jupiter, Juno and Galileo, who discovered in 1610 that Jupiter had moons.

What is it looking for?
Jupiter is enormous; it’s two and a half times larger than all the other planets in our solar system combined. It’s made entirely of gases and is believed to have no solid surface. The planet rotates at an immense speed, completing one rotation every ten hours, and telescopes have shown us that it has a cloudy atmosphere with colourful spots and stripes. The largest of these, known as the Great Red Spot, is a storm that is several times the size of Earth and has been raging for more than 300 years.

This mission is the first time that humans will be able to glimpse what lies beneath Jupiter’s cloudy atmosphere. The main objective is to understand how the planet formed and evolved, which will give us more information about the formation of gas giants as well as the rest of the solar system. Juno will also measure the quantities of water and ammonia within the atmosphere, examine the magnetic field that surrounds the planet, observe any polar auroras and measure the gravity to see whether a solid core may exist after all.

We are lucky in the western world. We are entitled to a free education until the age of 18. You might not always feel like going to school, but you are able to learn about loads of different topics, which will help you find a job when you are older. Not only that, but school can be great fun too – we bet you have a favourite subject, that you love to learn about.
A lot of children across the world don’t have this opportunity. Sometimes it is because the children are too poor to be able to afford to go to school, and there is no way they can pay for uniform, travel and schoolbooks. Sometimes it is because the government doesn’t provide free education where they live. Sometimes it is simply because they are girls. You might have seen the story of the girls in Nigeria who have been kidnapped, because they wanted to go to school – we are all hoping very much that they are soon home with their families. Now more than ever, it is vital to ensure children can go to school safely.
Do you ever wonder why people can’t pronounce your name correctly? Or struggle to say a friend’s name right sometimes? Here Avani tells us about her experiences, and how we can make the effort to pronounce things as best we can!
Do people always get your name wrong?
My name is Avani and let me start by saying: I get it.
Sometimes I spend ages teaching someone how to say my name properly (Uvni would probably be the best way to write how it’s pronounced) and other times I really can’t be bothered. I wish I had an easier name, or that people would just work harder to get it right!
Why do we find some names really difficult to pronounce and others really easy?
Here in England, people have names which come from all over the world. These names might be from places where a different language is spoken, and the different languages may also use different letters or characters to those we use for English.
My family, for example, come from a part of India called Gujarat. The Gujarati language uses a syllabary (a set of sounds) rather than an alphabet, but the syllables don’t always match up with English letter. The ‘v’ in ‘Avani’ (વ in Gujarati script) should actually be pronounced somewhere in between the English ‘v’ and ‘w’ sounds, but there isn’t an English letter that sounds exactly the same and this makes my name harder for people to remember! Also the ‘a’ and ‘u’ sounds in Gujarati are written using variations of the same symbol (અ (u) and આ (a)), which is why my name is spelt with an ‘A’, but pronounced using a ‘U’. Here’s what ‘Avani’ looks like written in Gujarati: અવનો – cool, right?
Languages which do use the same letters as those in English, may not pronounce all of them in the same way. This means that names that look similar on paper may be pronounced differently depending on where in the world someone lives. In Spanish, for example, the ‘j’ and ‘x’ letters are more like (but not identical to!) the English ‘h’, and in German, the letter ‘j’ sounds more like the English ‘y’ – can you imagine all the different ways people around the world must pronounce ‘Jesus’? You can listen to a few here!
It’s not only names from other countries that are hard to pronounce though! Have you ever thought about which common English names might be tricky for someone learning the language to get their head around? What about the name ‘Thomas’? We say it with a hard ‘T’ (like the one in ‘tree’, rather than the one in ‘three’) even though it is spelt with a ‘Th’, and we say the name ‘Charlotte’ with a ‘Sh’ sound (like in shop) even though it is spelt with a ‘Ch’ (like in chop). It must be hard to keep up with which names follow the usual pronunciation rules (like Theo or Charles) and which ones don’t!
What can I do if I think I’m pronouncing someone’s name wrong?
It is always worth checking with someone if you think you’re saying their name wrong – even if you’ve known them for ages and are embarrassed about asking, chances are they’ll be really glad to have an opportunity to correct you! However, it’s also important to remember that even if you know that the way someone says their name is different to the traditional way of saying it, you should always say their name like they have asked you to. Many people living in England, for example, prefer to go by a nickname or a more ‘Anglicised’ (English-sounding) version of their name to make things a little easier – so if you know a ‘Jesminder’ who prefers ‘Jess’, or a ‘Paulo’ who prefers ‘Paul’, you should respect their decision!
If you’ve just met someone new and have forgotten how to pronounce their name (or even if you’ve met them a few
times) – don’t despair, they probably won’t mind if you ask them again! If you are too embarrassed, though, there is a huge variety of pronunciation websites out there which will be able to help you. Click here for a good one!
Do you have a hard-to-pronounce name? Or have you ever been in an embarrassing situation over getting someone’s name wrong? Do you live in another country – which English names do you really struggle with? I’d love to hear your stories!
As well as trying to get people to say her name right, Avani Shah is currently working on a book for 8-12 year olds. She also blogs about her childhood and teenage experiences (Away with the Mice) and writes about words, etymology, and spelling for a website called Spellzone.
There’s no getting around it – school can sometimes feel like a drag. We’re willing to bet that some of these cool gadgets and new technology would make school life much easier!
