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.

What is it REALLY Like to Grow Up on a Farm
If you are growing up in a city or town, you may have sometimes wondered what it is like to grow up in the countryside. Clio lives on a farm in England and agreed to tell us what it is really like to grow up on a farm
Homemade Mother Day Gifts – Written by You
Mother’s Day origins can be traced to the UK, when Mothering Sunday was celebrated long before it saw the light of day in the USA. Each year in the run up to Mother’s Day, lots of us are wondering ‘What can I get my mom’.
OK, so a bouquet of flowers is very original, but maybe a bit too obvious? A box of chocolates is a bit too common! But how about something that would last forever! Here are my favourite ideas for homemade Mother Day gifts:
Living With Rosie – My Child Has Special Needs
Rosie wrote an article last week for Jump! Mag, telling us about her life on a farm. What you did not know when you read that piece, is that Rosie has special needs. Her mother explains how it is to live with a child with special needs.
I believe that you know immediately after giving birth that your child is different somehow.
As they grow, you notice that some milestones are different from the ones that your other children had and you silently chide yourself for comparing them.
Slower with walking, not speaking, unusual behaviour, unusual reactions to noise or red food.
You live with it every day and it becomes normal behaviour to you and your family, you adapt to the child’s needs and try to help them make sense of all that their jumbled up senses bring them.
