Hi, I've got everything you need to know this Thursday afternoon.

Coming up - a multi-millionaire's mission to Mars and amazing tale of

survival in South America. OK, but first, to a truly historic event

happening right now. Pope Benedict XVI's time at the top of the

Catholicure is coming to an end, as he officially retires and just

moments ago he left the Vatican in a helicopter and will stop being

Pope at 7pm. It is a massive moment for more than one billion Catholics

across the world and also an unusual one. No-one has given up

the job of Pope for 600 years. To Catholics across the world, this

man is God's representative on Earth, until around 7pm tonight.

Pope Benedict XVI is saying goodbye to one of the world's oldest and

most influential roles. As head of the Catholic Church, he has been in

control of the largest group of Christians, making decisions which

affect more than one billion people. If you are the first Pope to retire

in nearly 600 years, how do you go about doing it?

Pope Benedict XVI will move house, change his name and even his

wardrobe. He will swap the outfit and the red shoes for plain white

robes and plain brown shoes. A special golden ring he has worn as

Pope will be destroyed. He will spend his time praying for the

Church. Pope Benedict has said he faced

choppy waters during his eight years in the job. It is because the

Catholic Church has faced many big challenges, including accusations

of some priests mistreating some people.

The BBC's Alan Little is in the Vatican.

The Church is reeling dramatically in Asia, Africa, South America. The

men who pick the next Pope are mainly Europeans. The new Pope will

have to try and close the gap between the Church leaders in there

and the Church around the world. As Catholics around the world say

goodbye to Pope Benedict XVI, they are getting ready to welcome a new

leader who will have a lot of work to do.

Some of Britain's biggest Olympic stars have been honoured by the

Queen at braps. Nicola Adams, the first ever -- at Buckingham Palace.

Nicola Adams, got an MBE from Her Majesty, as did Greg Rutherford.

Jessica Ennis, who got an MBE two years ago is now a CBE. That is

Commander of the British Empire. This is what she had to say.

just said it had been a fantastic year and how is training going. I

was so nervous that you kind of forget what she said. But to be

here, in Buckingham Palace, I would never have imagined that at the age

of 10. Next an American multi- millionaire has unveiled an

ambitious plan. Dennis Tito was the first private space tourist when he

paid �30 million for a ticket at the International Space Station. He

says his mission is possible. The spacecraft will loop around Mars

but not land on the planet. He is looking for a couple who will be

able to put up with each other for the 501-day journey in a tiny

capsule. Who would you like to You can let us know who would you

like to spend 501 days with. We'll have a report on that at 6.50pm.

Watch out for the flashes coming up. A man has been found after three

weeks lost in a national part in Chile. He kept himself alive by

eating insects and plants and was found by children on a boat. He had
