It's Saturday, and here's what's on the show today.

A light festival lights up London Town.

And hope for elephant numbers in Cambodia.

Let's start with Tim Peake's epic spacewalk.

Yesterday he became the first British person ever

He spent a slightly shorter than planned five hours in space,

after his fellow astronaut said he had water in his helmet.

But they completed their main job, and replaced a faulty power unit.

Migrants and refugees have been leaving their homes in places

like Syria and Afghanistan, where there is fighting,

Many travel great distances in search of a better life in Europe

and some end up living in makeshift camps, like in Calais in France.

And they hope to make their way to the UK.

Now the French government have asked them to leave the camp.

BBC Reporter Simon Jones is in Calais and sent this report.

This is the area known as the jungle, it is home to around 4000

people, including some children. They come from countries like

Afghanistan and Sudan, because they feel they are not safe there, but it

is close to a main road where some people try to get on lorries heading

over to England. The authorities don't want that so want the people

here to move. Some people are, you can see that happening here, the

authorities say the living conditions aren't good enough here,

it is a muddy and freezing cold, so they've set up a brand-new camp on

the other side of the jungle. That is made up of shipping containers

and can house up to 1500 people. The idea is people get out of the cold

and the mud, the bug problem is, many people say they simply don't

want to go there because there's a of community here and they feel the

other shelter is a bit like a prison camp, so they are resisting that and

some say they are refusing to move out of designated zone.

And if you want to know more about the migrant crisis,

then head to our website for lots more information.

To some hopeful news for elephants in Cambodia in South East Asia.

A conversation group says they've seen an increase in the numbers

of elephants and bigger groups roaming around.

Companies cutting down trees for wood had been putting

the animals' lives at risk, but these new numbers are hopeful.

The streets of London have been dazzling with this

It's the biggest to ever hit the capital, with 30 different light

shows transforming some of the city's most famous buildings

and transport into multi-coloured works of art.

That's all from me, Newsround's back just before 12.
