Good morning, Ricky here, live with your Saturday morning

First this morning to a brand new theory about how our

Scientists in California say that Earth is made up of two

planets that collided four and a half billion years ago.

The impact between Earth and a baby planet called Theia was so strong -

Researchers say a chunk of that was knocked

British Astronaut Tim Peake is getting stuck into lots

of science experiments up on the International Space Station.

He's taken more than a million seeds of rocket up to space with them

and will be handing them out to more than 10,000 schools

From the time British astronaut Tim Peake blasted off into space, he has

been keeping us entertained with the science behind his mission, from

telling us how to go to the toilet in space to his epic spacewalk, now

he is asking for your help with his project. Now the seeds are on the

International Space Station, I will pack them up at the end of the

Mission and send them Back to Earth and when they arrive they would be

sent to thousands of schools to grow alongside the seeds that have not

been up here in space as part of our special experiment. Kids here are

among those from 10,000 schools in the UK taking part. We are going to

get a packet of these space seeds. When Tim Peake comes back down from

earth we will do some experiments. I can't wait to plant it and see how

it grows to stop I have watched every broadcasting is done and I am

really excited and my aim is to be like him. I am looking forward to

testing it out. In space it is different to earth, I think that

once they plant the rocket seeds, instead of the stem going up, it

will go down. That is what I am thinking. At the moment, getting

food in space is not an easy job and packets of food don't exactly look

very appetising! It is hoped that the work these people are doing will

help astronauts grow their own food on the International Space Station.

Good luck! At the Australian Open
