Hey, guys.

Martin here with the Friday morning top news stories.

Coming up:

British astronaut Tim Peake is getting ready to take

a walk in space.

Plus, who's been nominated for a Brit award?

It's a big day for British astronaut Tim Peake as he prepares

to do his first ever spacewalk this afternoon.

He'll be helping to restore power to one part of the station.

Here's Ayshah with what's going to be happening.

At around 1255 later today you might be finishing your lunch,

but somewhere in space Tim Peake will be about to take

a momentous step.

He will set for outside the International Space Station

for his first spacewalk.

It's a huge moment for any astronaut.

Spacewalks are the most exciting and challenging thing an astronaut

does, the hardest thing we do as human beings.

It is the most hostile environment you can imagine.

For the next 6 1/2 hours he will be out in space repairing a broken

power unit on the outside of the station.

He will be with a fellow astronaut and their every move is guided

by a team back here on earth.

Everything down to the order in which tools and equipment

are attached to their space suits has been carefully planned.

We have planned in meticulous detail the procedures.

We've used computer simulations to see exactly where we will go

and what we will be doing.

I think it's going to be the most exhilarating feeling imaginable.

After repairing the unit, his next job will be to connect

a brand-new cable.

And all the time, as we'll be whizzing by below them.

In fact, the ISS orbits earth every 90 minutes so they will do this

in a cycle of 45 minutes of daylight and 45 minutes of complete darkness.

At the corner of your eye you're seeing the planet rotating below

you so how do you stop getting distracted because you have

the whole universe to look at, but you have to undo screws

and not drop them?!

It is another part of Tim's exciting mission in space.

Canadian astronaut Chris Hadfield spent more than 150 days on space

taking part in two space walks.

He says they're are a crucial part of life on board the station.

We'd been training for years to do spacewalks.

You have to be strong and fit.

Regular maintenance is required to keep the space station running.

Unlike a car where you can pull over and call a tow truck,

if the station had a serious problem, you have to go

outside and fix things.

Today, Tim Peake will join a small group of astronauts who have

completed a spacewalk.

European astronaut Luca Parmitano told Newsround how he felt

when he stepped out into space.

It was absolutely fantastic.

I was giddy with excitement.

For me, it was one of the most exhilerating experiences ever.

Even though I was a test pilot, being on top of the world outside

a space station looking at the earth through my space helmet

and operating all this cool equipment, including

being inside a space suit was a really fantastic moment.

Emotional and the realisation of a dream.

Mostly, we know it's important.

There are a lot of people counting on you to perform really well

for your tasks so that the space station is safe and can keep going.

Head over to the Newsround web site to find out everything you need

to know about Tim Peake's spacewalk.

There's also a gallery of spacewalks over the years.

Adele, James Bay and Years Years lead the way with four nominations

each for this year's Brit awards.

All the nominees were announced at a special ceremony in London

and Leah was there for us.

Just a warning, there's some flash photography coming up.

The countdown to the Brit awards has started and leading the pack

with four nominations are Brit band Years Years including best

single for King.

It's an unbelievable thing.

It doesn't quite...

It is also so new, we just found out, so it's quite shocking.

Not far behind with three nominations including Best

female is Jess Glynne.

Tell us what it means to you as an artist.

It means the world to me.

It's like being recognised for doing a good job in what you do out of

thousands and thousands of artists.

It's like winning really.

Yeah, it's an indescribable feeling.

But one person with his hands already on a Brit award is Critics'

Choice winner, Jack Garrett.

I'm very fortunate I been giving this award and I'm so grateful.

But we're all in this together and that's what music is about.

It's about connectivity and sharing emotions.

So the nominations are in and we've been chatting to the stars

on the red carpet, but they'll have to wait until next month to find out

if they are a winner at the Brits 2016 and,

more crucially, if they'll get their hands on one of these.

That's all from me and the Newsround team this morning.

The Newsround web site will keep you updated through the day

with Tim Peake's spacewalk.

Ricky will be back at 4.20.

Have a great day.
