Morning everyone, Leah here with today's Newsround.

First, in a few hours' time, one of the most ground-breaking,

epic space missions of our time, will reach its grand finale.

After launching in 2004, it took Rosetta ten years to catch

After such a long journey, you'd hope things wouldn't

In 2014, Rosetta tried to attach a special space probe called

But instead, it bounced a few times and got stuck

Bad news for a space probe that's powered by sunlight.

With no sunlight, Philae's batteries ran out after just three days.

In 2015, Philae woke up from hibernation as the comet it's

on got nearer to the sun and sent back lots of information to Earth.

And in 2016, the location of Philae was discovered.

It was wedged in a dark crack on the comet.

While all this has been happening, the Rosetta spacecraft was orbiting

around the comet but now its journey is coming to an end with a bang.

Rosetta will join Philae by crashing into the surface of the comet,

sending lots more info back to Earth in the process,

Well, Rosetta's had quite a journey and joining me now to talk

about it is space expert, Dr Sarah Crowther.

Thank you for joining us. Such an important day-to-day. What will

Rosetta teach us? It has been a static mission where we have learned

a lot about comets and how they behave. It was ground-breaking

because Rosetta was the first spacecraft to orbit the comet and

the Philae lander was the first to land on a comet. They have taken

hundreds of pictures, analyse the dust on the comet so we have learned

a lot about what they are made of and how they behave. Why does it

have to end now? It is a shame but the comet is moving away from the

sun and the spacecraft is powered by the Sun said there is not enough

energy to keep it going. So they will crash it into the surface this

morning and as it gets close to the surface, we will get close up photos

of the surface and we will be able to take data as well. So exciting

when we get those pictures. Thank you for joining us!

Next, Syria used to be a country where children lived normal lives,

going to school, playing with friends and

That isn't possible any more because of the war that's

Now in the country's biggest city, Aleppo, there are signs that it

For more than five years, Syria has been at war.

Different groups are fighting for power and control

Meanwhile millions of Syrians have been forced to leave the country

and find a safer place to live, but some families have had no choice

Around four million people live in Aleppo today.

Right now, Aleppo is split with a number of groups controlling

different parts of the city and there's awful fighting

The BBC's James Longman is in Lebanon, a country next

to Syria, he's been reporting on the crisis in the area.

You can see how many buildings have been destroyed over

People living here have been cut off from food, from medicine,

So life has been very, very difficult.

As you can see from these pictures, much of Aleppo has been destroyed.

Bombs have been dropped onto streets, killing

people and leaving behind these large craters.

Many children are the victims of this conflict.

Syrians tend to have large families and there are lots of children

Some say that maybe half of all the people who have been

killed or injured in Syria, in eastern Aleppo, are children.

Parts of the city have no clean water and vital supplies like food

Still these children are trying to get by and doing what they can

Some say compared to five years ago, the city is hardly recognisable.

And no one knows when the conflict will come to an end.

And if anything in the news upsets you there's lots of advice

That's also where you'll find our full guide to what's

That's all from me, Newsround's back at 4:20pm this afternoon.
