Good afternoon, news fans.

I'm Jenny, live with your last Newsround update of the day.

You won't want to miss all this.

Find out what happened when this record-breaking spaceman

returned to Earth.

And we want to know your World Book Day plans!

But first to that story that's had you sending in your views all day.

We're asking, should tackling be banned in rugby games?

Today a group of more than 70 doctors and health experts said

they want to stop tackling in school rugby, because they say it's

dangerous.

Rugby is brilliant because it gives me confidence.

It gives me adrenaline and makes me feel stronger.

It keeps you fit and healthy.

It is compulsory at many schools in the UK.

They are big fans here at this school in Cheshire,

but now some doctors say that the way rugby is played

in schools should change.

They have written to politicians, asking them to ban tackling

in school and club games for anybody under 18.

The risk of injury can be 28% for a child playing in a season,

and an 11% risk of being concussed.

These are serious injuries.

The way of preventing 90% of injuries is to take out

and remove the tackle and contact from the game.

The PE teacher at this school says tackling can be safe.

We are trying to minimise the risks, make it as little as possible,

so that people don't get injured, but focus on the main things,

the core values.

We make sure all staff are trained and students are aware,

and when it is appropriate for them to go into contact in a game

situation, they have done the progress.

I think it should not be banned.

As long as you are taught how to do it safely,

you are OK.

When you do a fair tackle, it gives you the confidence

to boost your team and help them win the game.

You can injure yourself in any sport.

The contact makes you more excited and gets your adrenaline going.

It is an important part of the game, it becomes natural and it is fine.

We have been asking for your comments, not all of you agree

it should stay.

The people in charge of running rugby in England told Newsround

there are special rules for young players to make the sport as safe

as possible and a lot of research goes into minimising any

risk of injury.

Record-breaking US astronaut Scott Kelly came back to Earth

with a bump today after almost a year in space.

He was joined by Russian cosmonaut Mikhail Korniyenko,

and the pair landed at around 4:30am this morning.

They had to be helped out of their capsule,

because being in space weakens your muscles.

During his stay on the International Space Station Scott shared some

incredible images and videos of our planet, so let's take

a look.

340 days in space, and during that time, Scott Kelly has

shared his experiences online, from chilling out with his

colleagues to fantastic views from above.

He also carried out lots of work as well, including important repairs

to the ISS.

And of course there was always lots of time for fun.

This is Scott dressed up.

But it does not stop there, his identical twin Mark,

also an astronaut, stayed grounded during the year.

Nasa will now test them both to find out how a year of weightlessness

affects the body.

It is hoped they will find out more about what it is like to travel

to Mars, which would take a year of space travel.

The Track Cycling World Championships kick off

in London today.

Among the riders is double Olympic gold medallist Laura Trott.

She told us about the moment she realised as a child she could be

a cycling superstar.

We used to go Welling and do a track meet on a Friday night.

I was in the B group, and the A riders would be

handicapped, they had to catch you for a lap.

A guy pushed me off, I went flying, I did not have to pedal.

I remember winning and I thought, maybe I can do this,

and it took off from there.

Now, tomorrow isn't just 3rd March, it's World Book Day,

a huge celebration of everything reading-related!

It's marked in over 100 countries round the globe,

and we want to know what you're doing for the day.

Are you dressing up?

Reading a favourite book?

Or even putting on a play?

Whatever you're doing, we want your photos and videos now,

so get online and send them our way.

That's all from the team today.

Newsround's back right here with all your top stories

on World Book Day tomorrow morning.
