It's coming up to 8:17 this Monday morning,

you're live on CBBC with Newsround, I'm Ricky.

Coming up: British astronaut Tim Peake

explains just how you use the loo in space.

First, a massive parade of Great Britain's Olympic

and Paralympic heroes is happening today in Manchester.

Loads of Rio 2016's stars are here in MediaCityUK today,

ahead of this afternoon's celebration through

the city's streets, before another parade in London tomorrow.

More than 150,000 people are expected to come out to watch,

and Paralympic swimming star Ellie Simmonds can't wait.

I'm very lucky that I've been able to go to three

after Beijing, and after London, and after Rio now,

and to come here today in Manchester and then London tomorrow

to thank the people that supported us through the summer

of the Olympics and Paralympics is going to be exciting.

Here's a quick reminder of what makes them so great.

It was a massive summer for our Olympic and Paralympic athletes.

Years of training paid off, and they smashed it.

and Jenny will be live from there for Newsround at 4:20.

Moving on to these incredible pictures of a Chinese space rocket

blasting off from the Gobi Desert in east Asia.

It's sending two astronauts to China's new space station.

They'll spend a month carrying out different experiments.

Now someone who knows just what it's like to be in space

is this guy, British astronaut Tim Peake.

He's been travelling the country meeting children

since returning from the International Space Station.

This weekend, he met with Jenny here at Newsround HQ

After six months floating in space, Major Tim Peake landed

at Newsround HQ to a reception that was out of this world.

Olivia, who is nine, from Leicester, wants to know,

what does it feel like to be able to float around?

Yeah, floating in space is really liberating,

When you first start, you're not very good at it,

and your legs and arms are flailing everywhere,

When you get used to it, you can just push off with one finger

and float down the other end of the space station, it's great fun.

This next one you've already spoken about it a little bit,

but it's something that pretty much everyone wants to know -

and how did you get rid of the waste from the ISS?

It's a big one, it is a big one. Yeah, important question.

Right, so in space, to keep everything under control,

you must have airflow, airflow is the key,

so you have a little vacuum pump to the loo,

and that creates the suction so you can pee into the tube,

and it keeps everything going in the right direction.

And the important thing is, when you've finished peeing,

you keep the pump running for at least 30 seconds,

because otherwise, if you switch it off too soon, then it has not

We've got some questions from these guys, bear with us one moment.

Actually, I took a teddy, I've got two young boys,

so I took a small teddy in for each of them,

and my excuse was it was for my two small boys,

but I had them every night with me so...!

You've got one too. Do you think aliens really exist?

Of course they exist! Yes, absolutely.

I think we are actually fairly close

to finding evidence of life, past life, on Mars,

that's certainly what we are searching for, robotic vehicles.

little green men running around, well, who knows?

The universe is an extremely large place, and there is

a huge probability that there is intelligent life out there.

From intelligent life to wildlife, a rhino that got stuck

in a tyre has been rescued in Zimbabwe, in southern Africa.

The animal managed to get his snout trapped,

When it became clear he couldn't free himself, vets stepped in

and gave him some medicine, so they were able to get it off.

millions of people in the US will vote for a new President.

And we've got a team in the US right now who are waiting

for your questions to put to children in America.

If you're interested in the big vote,

or even if you want to find out how Americans celebrate Halloween,

get those questions into Newsround online right now.

That's all from me, Newsround's back on CBBC this afternoon at 4:20,

when we'll be live from the Olympic and Paralympic parade.
