It's Tuesday, I'm Jenny and this is Newsround.

A special camera gets rocketted into space.

We get a pigeon's eye view of pollution....

First up, some space news and a new camera satellite has been

launched by the European Space Agency.

Satellite Sentinel 2B will join another satellite already in space

to take pictures of the Earth's surface every five days and send

back information about pollution levels in lakes and coastal waters,

as well as checking on the world's forests.

Also helping to measure pollution are some unexpected

Yes, pigeons are being used in an experiment to learn

Martin has been 'coo-vering' over the story.

I see them all the time in the city, trying to find bits of food

But how are they linked to pollution

- apart from both starting with the letter P?

Well, scientists are using pigeons to gather information by strapping

It is known that pollution that comes of our cars with diesel

engines rises to rooftop level, but what isn't known

is what happens next to the pollution, where does it go?

I thought, well, birds, they fly everywhere.

If they can carry the sensors, and they are tiny enough, we

can start to understand the dispersion

Birmingham University are carrying out a test flight.

It is the first time we have done this.

One of the pigeons is fitted with a small, lightweight sensor

Just six minutes later, the pigeons are back and the sensor

Rick and his team have been able to find out the route the pigeons

The information will help them to figure out how pollution

So thanks pigeon number 80, you've done everyone proud.

From pollution high in the air, to pollution down on the ground.

One student is helping experts find out how clean or dirty

the air we breathe is, when we walk around.

Logan is doing a very important job. You might wonder what is in his

backpack. He has been testing pollution levels in Leicester, with

something called a portable air monitor. This kit measures chemicals

in the atmosphere. Researchers send him out and about two places where

there is a lot of traffic to test things out. We spent a while talking

to Logan in a sheltered location and there were some cars there which

became parked up. The fascinating thing is during that period when

standing still we experienced high levels of pollution than with

traffic on the junction. What do his friends think of this information?

People have stopped waiting near the buses after school for their

friends. They have been waiting closer to the leisure centre and

further from the buses. It is obviously had an impact. It is hoped

if people know how much pollution is around them at the way they look at

the issue will change. Chelsea are now 10 points ahead at

the top of the Premier League table. Last night they beat

West Ham 2-1 thanks to goals Manuel Lanzini managed to get a goal

for the home side in injury time. President Donald Trump has

signed a new version The first version led

to lots of protests. This new version bans visitors

from six mainly-muslim countries, from coming to the US for three

months, and puts a stop to all This has been

bamboozling me for years. It is a bit of a grey

area until now. Pandas have unique black

and white patches. Unlike some other types of bears,

pandas are active all year round. As they go in search

of bamboo to eat they move from warm rain

forests to snowy mountains, The white helps them to blend

into snowy surroundings and the black helps them to

hide in shady forests. The black ears might look cute

but they are actually a warning They vary in shape and size

from panda to panda. It is thought they help

them to recognise each
