0:00:03 > 0:00:05Hello, I'm Jenny, you are live with Newsround.
0:00:05 > 0:00:08And you're not going to want to miss all this...
0:00:08 > 0:00:13Could geckos save the International Space Station?
0:00:13 > 0:00:15And don't look down!
0:00:15 > 0:00:25We'll check out the world's longest sky walk.
0:00:26 > 0:00:29First up to Wimbledon and not a bad day for the Brits.
0:00:29 > 0:00:33Heather Watson has made it through to the next round beating
0:00:33 > 0:00:38Anastasija Sevastova in two sets.
0:00:38 > 0:00:41Aljaz Bedene also beat Damir Dzumhur three sets to one.
0:00:41 > 0:00:47Great news for British number one Johanna Konta as well who has
0:00:47 > 0:00:49literally just beaten Donna Vekic from Croatia.
0:00:49 > 0:00:51Sticking with Wimbledon - picture the scene.
0:00:51 > 0:00:53You've just watched your favourite player, they throw their towel
0:00:53 > 0:00:56into the audience, it's heading right for you.
0:00:56 > 0:00:57But then...
0:00:57 > 0:00:59It's pinched by someone else!
0:00:59 > 0:01:02That's exactly what happened to this guy after watching
0:01:02 > 0:01:04American Jack Sock play.
0:01:04 > 0:01:08Luckily Jack is onto it and wants to send the fan a new towel.
0:01:08 > 0:01:11Hopefully a clean one.
0:01:11 > 0:01:14And of course one match we're looking forward to is Andy Murray,
0:01:14 > 0:01:16who should be on court soon.
0:01:16 > 0:01:19But what does it take to make a Wimbledon champion twice over?
0:01:19 > 0:01:23We've been finding out.
0:01:23 > 0:01:25We are the mini Murrays!
0:01:25 > 0:01:28I'm Andy, nice to meet you.
0:01:28 > 0:01:31Shall we hit a few balls together?
0:01:31 > 0:01:32Wow!
0:01:32 > 0:01:33That was bigger than me.
0:01:33 > 0:01:36What is the best moment of your life so far?
0:01:36 > 0:01:37Best moment of my life would be
0:01:37 > 0:01:41when my daughter was born.
0:01:41 > 0:01:45It ended up being a good year on the court, but, yeah,
0:01:45 > 0:01:50it was a better one off it for sure.
0:01:50 > 0:01:53Who inspired you to play tennis, and what would your advice be
0:01:53 > 0:01:55if someone wanted to be a tennis player
0:01:55 > 0:01:58just like you?
0:01:58 > 0:02:00I'd say my mum inspired me, and my brother,
0:02:00 > 0:02:01to play tennis.
0:02:01 > 0:02:04She used to play when she was younger and she really
0:02:04 > 0:02:08coached me and my brother until we were like nine or ten years old.
0:02:08 > 0:02:11Best piece of advice I could give to anyone
0:02:11 > 0:02:12wanting to play tennis would be
0:02:12 > 0:02:17to have fun when you are a kid, enjoy playing,
0:02:17 > 0:02:20and to listen to your coach.
0:02:20 > 0:02:22There we go, that's excellent!
0:02:22 > 0:02:23Whose cooking do you prefer?
0:02:23 > 0:02:25Your gran's, mum's or wife's?
0:02:25 > 0:02:28PS, I have tasted your gran's cooking at the Dunblane tennis
0:02:28 > 0:02:30courts, and it is delicious.
0:02:30 > 0:02:33HE LAUGHS Lucky you!
0:02:33 > 0:02:35That's a really tough question.
0:02:35 > 0:02:39My gran has got a lot of experience getting so I would
0:02:39 > 0:02:42say it'd just, JUST be her, but my wife is also a good, good cook.
0:02:42 > 0:02:44It isn't my mum, she would definitely be
0:02:44 > 0:02:52third on the list.
0:02:52 > 0:02:53Poor Judy.
0:02:53 > 0:02:56Next, if you think rubbish can be a problem here on Earth,
0:02:56 > 0:02:58imagine the trouble it can cause out in space!
0:02:58 > 0:02:59Step in super gekko...
0:02:59 > 0:03:01It'll all make sense when you watch this.
0:03:01 > 0:03:02Here's Whitney.
0:03:02 > 0:03:04There's a big problem up in space.
0:03:04 > 0:03:09Right now, about 500,000 pieces of human made debris are whizzing
0:03:09 > 0:03:13around space and orbiting our planet at speeds of up to 17,000 mph.
0:03:13 > 0:03:19This debris poses a threat to our satellites and space stations.
0:03:19 > 0:03:22And it is getting scientists thinking,
0:03:22 > 0:03:25the solution, super robot space geckos.
0:03:25 > 0:03:28What?!
0:03:28 > 0:03:31Top scientists have developed a tool to grab objects in
0:03:31 > 0:03:32space.
0:03:32 > 0:03:35It has been inspired by gecko feet and how they grab onto surfaces
0:03:35 > 0:03:42when climbing.
0:03:42 > 0:03:50Geckos' toes can hold on to almost any smooth surface,
0:03:50 > 0:03:56their feet are covered in tiny rubbery hairs
0:03:56 > 0:03:57that grip the surface
0:03:57 > 0:03:59tightly, are also super easy to remove
0:03:59 > 0:04:00when force is applied in the
0:04:00 > 0:04:01other direction.
0:04:01 > 0:04:03This allows a gecko to climb almost anywhere.
0:04:03 > 0:04:05The scientists copied these tiny, tiny
0:04:05 > 0:04:06hairs for their grip.
0:04:06 > 0:04:08It has wedges one tenth of a millimetre wide.
0:04:08 > 0:04:14The robotic grabber can grip, hold onto
0:04:14 > 0:04:16and move around even large smooth surfaces
0:04:16 > 0:04:17in zero gravity and the
0:04:17 > 0:04:18vacuum of space.
0:04:18 > 0:04:21A possible solution to a big problem up there from a tiny
0:04:21 > 0:04:23little creature down here.
0:04:23 > 0:04:26If you're not a fan of heights, I'd look away now.
0:04:26 > 0:04:28This glass walkway in China is the world's longest.
0:04:28 > 0:04:31It hangs more than 120 metres above a gaping
0:04:31 > 0:04:37chasm, and is delighting and terrifying visitors.
0:04:37 > 0:04:46Presenters Phil and Holly were in for a bit of a surprise
0:04:46 > 0:04:48during their daytime tv show,
0:04:48 > 0:04:50a pony poo'd live on air, in the middle of their set.
0:04:50 > 0:04:51Not so cute now!
0:04:51 > 0:04:54Holly said it was the best thing she'd ever seen.
0:04:54 > 0:04:56Frankly, it's left me a little HOARSE.
0:04:56 > 0:04:58That's all from the team today, but set your alarm clocks,
0:04:58 > 0:05:00I'll be right here tomorrow morning at 7:40
0:05:00 > 0:05:00with even more Newsround for you.
0:05:05 > 0:05:08Imagine if snot was taking over the world. What would you do?
