Hi, guys - Martin here with the big news this Saturday.

Coming up...

A warm welcome for the International Space Station's

new batch of astronauts.

And a heroes' welcome home for the Wales footy team.

But first, Andy Murray is now one win away

from a second Wimbledon title.

The British number one beat Tomas Berdych in straight sets,

and made it through to his third Wimbledon final.

He'll take on Milos Raonic after the Canadian beat Roger Federer.

Tomorrow will be Murray's 11th major final!

You never know how many chances are you're going to have to play

You never know how many chances you're going to have to play

in grand slam finals, so you want to make the most

of your opportunities, and, you know, glad I managed

to get through.

And Andy Murray isn't the only Brit in a Wimbledon final -

Gordon Reid is through to the men's wheelchair singles final

after he won his semi-final against Belgian Joachim Gerard

in straight sets.

This is the first year that Wimbledon has had a singles

wheelchair tennis competition.

In about 20 minutes' time, defending women's champion

Serena Williams will take on Angelique Kerber in the final.

Serena's the favourite, being world number one and having

won Wimbledon six times, while it's Kerber's

first final there.

But before the final gets going, there will be a very important coin

toss to see which player gets to serve first.

Well, this year its Uma's job to toss the coin,

which means she'll be standing on Centre Court on women's

final day, right next to her sporting idols,

and I think it's safe to say she's pretty excited!

It feels amazing, just incredible, like, I'm literally living a dream.

I want to wish them good luck, and hopefully my favourite,

Serena Williams, will win!

Now, Wales didn't quite win the Euros, but they are still

winners in the eyes of tens of thousands of Welsh footy fans.

They lined the streets of Cardiff to welcome the boys home

after their historic journey at Euro 2016.

CHEERING.

It was a heroes' welcome for the Welsh football team

in Cardiff, as a sea of fans lined the streets to greet them.

SINGING AND CHANTING.

They have made history and given people great memories.

Proudest day of my life.

Yeah.

Brilliant.

Absolutely brilliant.

The boys have done really well out in France,

and it's making Wales proud.

Fans followed the celebrations every step of the way,

players thunderclapping in the sunshine.

The party continued with a massive concert in the Cardiff City Stadium.

Great to be Welsh, isn't it?

Doesn't come around very often, it's not

supposed to happen to us.

It's great.

It's amazing!

Brilliant, really good.

It was the first time that Wales had reached a major tournament

in nearly 60 years.

They made it to the semifinals of the Euros, the furthest

they've ever got before.

For the players, it was a chance to say thank you.

To get a welcome like this is incredible, and, yeah,

shows how amazing our fans are.

We couldn't have done it without everybody here,

and all the staff have been amazing, all the players have

been amazing, and...

Yeah, just a big thank you to everybody.

CHEERING.

It was a night that Wales fans will remember for many

years to come.

Up in space, there's been another warm welcome,

for three astronauts who've just reached the International Space

Station on the Soyuz spacecraft.

They docked smoothly earlier this morning after a two-day journey.

The astronauts come from Russia, Japan and the US, and join three

others who are already up there.

And another space mission that's gone smoothly this week

is Nasa's Juno spacecraft, which has started to orbit our solar

system's biggest planet, Jupiter, after an epic five-year journey.

Its job is to find out more about the gassy giant.

Here are five facts you might not know about it.

Jupiter's the biggest planet in the solar system.

It's so big that over 1,000 Earths would fit inside it.

But we don't really understand how Jupiter was formed, how it was made,

even where it was made exactly, and what is key to understanding

that is how we understand how the other planets in the solar

system were made.

Jupiter's got a really strong magnetic field.

What that means is it's got really bright aurorae -

the sort of northern lights that shine really brightly at the north

and south magnetic poles - and what we want to understand

is how are those aurorae generated.

When we look at Jupiter, we see these really beautiful cloud

belts, these sort of horizontal bands of different colours,

and they are made up of different elements in the

atmosphere of Jupiter.

There's winds circling around Jupiter at over 300 miles an hour,

and we want to understand how those winds are generated,

and where those colours are created.

Jupiter has four large moons - Io, Calisto, Ganymede and Europa.

Galileo was the first to spot these when he used a telescope to look

at them 400 years ago, and even today, you can see them

just with a pair of binoculars or a small telescope.

We are now able to find planets orbiting other stars,

and the easiest ones to spot are the largest ones,

ones like Jupiter, but they are very different from Jupiter,

so making sure we can understand Jupiter in our own solar system

will help us understand not only how our planets are made,

that how these other planets around other stars are made.

From a starry attraction to a slothy one.

This guy surprised people as he wandered around a town

in Peru in South America.

The sloth was found by a shop owner as he was about to open

for business.

He'd escaped from a local nature park.

The authorities were called, who took him back home.

That's all from Newsround on CBBC today.

I'm back here tomorrow morning just after 10am.
