Hi, I'm Martin with all you need to know this Friday afternoon.

Coming up on Newsround -

How many astronauts does it take to change a battery?

The drone's eye view of this wonder of the world.

And the mysterious eggs washed up on a German beach.

In two weeks' time this man - Donald Trump will become

the President of the United States.

But as he's getting ready to move into the White House,

he's been told to "grow up". Here's why.

Since Donald won the election, he's been pretty busy tweeting

what he thinks and not everybody likes it.

Including this guy - Joe Biden - President Barack Obama's

second in command.

Grow up, Donald, grow up.

Time to be an adult, you're President.

Ouch, Joe!

But why the playground insult?

It's all to do with a big row over the election

which Donald won in November.

American Spies say Russia got involved in the US election.

They say that Russia hacked into emails of members

of Hillary Clinton's team to find embarrassing information about her.

They say it was to help Trump and damage Clinton's

chances of winning.

But he's been spending a lot of time on Twitter saying he doesn't believe

America's spies have got it right.

He said, "So, how and why are they so sure about hacking

if they never even requested an examination

of the computer servers? What is going on?"

He's not the only one wondering that.

No one who is about to be President has ever acted like this before.

Some people are worried by it, but Trump supporters say this

is why he's different from other politicians.

It's probably the only thing everyone agrees on.

And to find out more about the row over the US election, go online.

Next up - space - and right now a team of two astronauts

from the International Space Station on a space walk.

They are outside the station to replace batteries on part

of the ship to improve its electrical system.

It is the seventh space walk for US astronaut Peggy Whitson.

The job is likely to take about six and a half hours to complete.

And from one epic mission to another.

William Lindesay, from England, has filmed the entire Great Wall

of China from the air, using a drone -

all 5,500 miles of it.

all 5,500 metres of it.

He's been obsessed with the wonder of the world, since seeing it

on a school map as a child.

His travels have taken him all over north China and even to Mongolia.

The last orca show will take place at SeaWorld, in San Diego,

in America this weekend.

The company has faced a lot of criticism over the last few

years, about the treatment and welfare of its killer whales.

I've has been finding out more.

Powerful and intelligent.

We're talking about orcas or killer whales, as they are better known.

For many years, these whales have performed in shows across America,

at amusement parks run by the company SeaWorld.

But not any more.

In 2015, Californian authorities banned SeaWorld

from breeding orcas in captivity.

And after a lot of pressure from celebrities and animal

rights groups, in 2016, SeaWorld announced they were putting

an end to killer whales performing shows in their parks.

This weekend marks the final show at one of those parks,

in San Diego in California.

SeaWorld currently has killer whale shows at two

other parks in America - in Texas and Florida.

But they will be gradually phased out as well.

Instead of performing tricks, the whales will now be used to help

teach people more about walkers.

Animal rights groups have praised SeaWorld for making positive steps

in the right direction. But some still think more can be

done to help protect the animals' welfare.

Some suggesting the whales should be moved to sanctuaries

by the sea where they can live in an environment closer to that

of their natural homes in the wild.

The fight for killer whales seems set to continue into the future.

But things are definitely changing for these underwater giants.

And finally, a flood of plastic eggs, containing tiny toys,

has been swept on to a beach on a German island

after a fierce storm.

The eggs seem to have come from a container

lost by a cargo ship.

Local children have been helping collect the unexpected

treasure, before it becomes a hazard for wildlife.

Egg-cellent news!

That's all from me, Newsround's back right here just before

9am tomorrow morning.
