What is Juno?

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.

Lots of Socks for World Down Syndrome Day

Do you sometimes wear non-matching socks? When you can’t find ones to match or just because you want to?  Well on the 21st March you have the perfect excuse to and Agi is going to tell you why.
Agi has been making videos about her life with her little sister, who just happens to have Down Syndrome, for many years. We asked her to tell us more about this condition, and about life with Magdalena and to share some of her videos with us.

 

Firstly though who am I?

I’m called Agnieszka (Agi for short) and I am home educated with my little sister Magdalena, who is 7 years old. I have a website which I blog on about our life together and anything else I am interested in. I want to be a filmmaker when I’m older, and you can view lots of films that I’ve made on my website, and Magdalena wants to be an artist. She is one of my best friends. We have loads of fun together, and I don’t treat her any differently or treat her ‘specially’, even though she happens to have Down’s syndrome. Which is where the lots of socks come in…but first, let me explain.

I would never have known this unless my little sister, Magdalena was born with an extra 21st chromosome.

Have you worked out yet why World Down Syndrome day is on the 21st of March?

It’s because people with Down syndrome have three chromosomes on chromosome number 21, instead of the usual two. This is also known as Trisomy 21.

Why is it Called Down’s Syndrome?

So why call it Down’s syndrome? No, it’s not because people with Down’s syndrome are ‘down’ or grumpy, it’s actually because Dr John Langdon Down discovered the condition, and it was named after him.

Lot’s of people my age don’t know what Down’s syndrome is, (actually lots of adults don’t either) and that can make them scared of what they don’t know about, so they ignore Magdalena or talk ABOUT her instead of TO her or say something unkind thinking she won’t understand or be hurt by it. So before I get onto the socks, I want to tell you a bit about what Down’s Syndrome is and what it isn’t!

Amazing Outdoor Art

A few weeks ago on Twitter we shared a picture of an electrical tower that German students had turned into a stunning 3D stained glass window. This got us thinking about other amazing outdoor art a little bit closer to home. Read on for some inspiring examples that you can go and see for yourself…

Awesome Women Who Disguised Themselves as Men to Follow their Dreams

Throughout history girls and women have been told, ‘You can’t do that! You are a girl!’ Luckily, this attitude is becoming less common in many countries and cultures, but what did women do in the past? If they wanted to be a doctor, a musician, a sportsperson or even a soldier?

Most women put aside their dreams or practised other activities that were deemed appropriate for women. Some women protested, like the suffragettes who demanded to be allowed to vote. And a small number of women went much further. Today we are taking a look at the women who disguised themselves as men in order to follow their dreams.

 

The first woman to circumnavigate the world – to go all the way around the globe. Born in France, and with an interest in botany (the study of plants), Jeanne became first the housekeeper, and later the partner of a famous botanist Philibert de Commerson.
