Hi, I'm Leah, it's Tuesday and this is Newsround, live on CBBC.

And superstar para athlete Hannah Cockcroft joins me in the studio.

First, it's a big night for England's Under-21 football team

who play Germany in the semifinals of the European Championships.

The match is taking place in Poland this evening with Nathaniel Chalobah

and Nathan Redmond facing a race against time in fitness

Now, they're one of Australia's famous species.

But koalas are having a bit of a hard time at the moment,

Since 2012, koalas have been listed as a vulnerable species

and now their numbers have fallen further.

Today, there are fewer than 40,000 left in the wild.

Mainly because of things like dog attacks, cars, vanishing habitats.

Koalas have declined by 50% in the last 15-20 years.

The very area that they want to get in and absolutely hammer is the very

area that is the highest koala habitat quality.

So, logging and deforestation is a big issue for koala

conservationists, but it's not the only problem.

Researchers say coastal gum trees, where the koalas live

and eat, could be affected by rising sea levels.

And if that happens, the tasty leaves of the trees

But there are a few ideas people are looking at to protect koalas

Like huge koala parks to help those that are at risk and stopping

So, hopefully, this will help them do what they normally do -

Next, there's just three weeks to go now until the World Para

All the big stars will be taking part and we're lucky enough

She won three golds at Rio and holds, not two, not three,

Firstly, with only three weeks to go, how are you preparing?

I am feeling really good, really excited to get back out in front of

a home crowd. Preparation is going really well. I have just compared

gully comeback from competing in Switzerland where I got five world

records. How do you focus on something as big as the

championships? Are you thinking about London, Rio, everything you

have won so far? You think about your successes so far, but once you

are on the start line, you try not to think about those things, it is

about the race ahead, focusing on each part of the race and following

through and making sure you are doing it right. It can be quite

difficult when it is a noisy crowd! The World Championships, it sold

loads of tickets, it must be fantastic knowing you are inspiring

a new generation of athletes, would be athletes. Yeah, the most tickets

we have ever sold already. We want more people there! We want to fill

the stadium. A British crowd is so passionate and we love not just the

British athletes but all of the athletes love to perform in front of

them. Jump onto the London 2017 website, get your tickets, we

promise we will do well. Come back and show us your medals. Thank you

so much. The SpaceX mission launched

from Florida and California in the US, marking a new age

for space travel! Getting a satellite

into space is a challenge. But it's getting easier

and a lot cheaper. This is the SpaceX Falcon 9 rocket

in action over the weekend. It just completed two missions in 48

hours, delivering ten So, what's so special

about the Falcon 9 rocket? Well, it can be used

time and time again. Once it has released

all of its cargo,... Looks like it did have

good recovery... ..it can return back to Earth,

usually on the landing zone, a floating ship on water just

like this one. But SpaceX has just started

to successfully land The company continues

to break boundaries. They even have plans to send

tourists around the moon. Finally, tips for packing,

things you might NOT Security staff found this crustacean

after they took a look It was very much alive

and it was travelling He was allowed to continue

to his final destination - after a quick photo

was taken, of course! Newsround's back here
