There has been a lot of excitement about the Juno probe this week, but what is it and what is its mission?
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.

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.

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.

This book is set in 1649, just after King Charles 1st had been executed. At the back of the book there are some historical background notes.
It is really hard to describe, because although it is set in a real time from history, it moves between two different worlds, it is unlike any book I have read before.
It is the best book I have ever read, I couldn’t put it down and read the 300 paged book in two days. It is packed full of mystery, magic and adventure, and history, with the slightest bit of romance.
The story unfolds through the eyes of six year old Coriander, who is almost 20 by the end of the book. One of things which is fun seeing change, is Coriander’s fear of the stuffed baby alligator in her father’s study, it holds the key to the cabinet in its mouth, and at the end, it comes alive (just like she had feared all along) it saves her-I can’t tell you how because it will spoil it!
The imagery throughout the novel is beautiful, and everything is described in great detail. Here is an example:
” Everything in the room was covered in a layer of thick dust. The curtains that the sun had been badgering were now no more than a mass of spiders webs. The bedroom covers were all torn and tattered, feathers split from the mattresses, and the wash basin was cracked and broken as if long abandoned. It was a room of rags and feathers, nothing more.”
The book has a fairy tale quality to it, because of the language Sally Gardner uses and the events of the story.
The characters are larger than life and dramatic, and at times frightening.
This novel’s ending was satisfying and felt complete. After reading this book I felt inspired to write a story set in a time from history also. One of my favourite things about the book, is how Coriander stands up for herself.
I highly recommend this book, I will definitely read it again!
I rate it 10/10, and would recommend to age 9-14
