0:00:08 > 0:00:11Afternoon all, it's Ayshah here.
0:00:11 > 0:00:15New ways to deal with space junk AND
0:00:15 > 0:00:25daredevil fliers test their wings.
0:00:25 > 0:00:27Ever fallen out with a good friend over something
0:00:27 > 0:00:31that's been posted online?
0:00:31 > 0:00:34Well, if you're the President of the USA and the Prime Minister
0:00:34 > 0:00:37of the UK, it can be even more awkward than usual.
0:00:37 > 0:00:39The US and UK are good mates.
0:00:39 > 0:00:42People call it the special relationship.
0:00:42 > 0:00:45The leaders are pretty close, too.
0:00:45 > 0:01:00British Prime Minister Theresa May was the first foreign leader
0:01:44 > 0:01:46on terrorism in the UK instead of criticising him.
0:01:46 > 0:01:47So why is this important?
0:01:47 > 0:01:49Well, world leaders, especially friends, are not supposed
0:01:49 > 0:01:52to argue in public like this.
0:01:52 > 0:01:55Some people are asking the question, is this the right sort of thing
0:01:55 > 0:02:01the President of America should be sharing on social media?
0:02:01 > 0:02:08And if you want to find out more about this story go online.
0:02:08 > 0:02:11Forget texting, snapchatting or instagramming your mates.
0:02:11 > 0:02:14These kids in Kidderminster are going old school.
0:02:14 > 0:02:17Dear Jasmine, thank you so much for your very lovely
0:02:17 > 0:02:19and well-written letter.
0:02:19 > 0:02:22Putting pen to paper, these guys are pen pals
0:02:22 > 0:02:26with the local home for the elderly.
0:02:26 > 0:02:31You get to listen to what places they've been to and what they have
0:02:31 > 0:02:35been doing and the cheeky stuff that they have done.
0:02:35 > 0:02:38You get to ask them all the questions you really want
0:02:38 > 0:02:41and most of the time, they answer them.
0:02:41 > 0:02:45So, without Snapchat or Instagram, they are still having fun.
0:02:45 > 0:02:48But what do their older pen pals think about it?
0:02:48 > 0:02:51So, Enid, I've got your letter from the school, from one
0:02:51 > 0:02:55of your pen pals called Tilly.
0:02:55 > 0:02:56Shall I read it to you?
0:02:56 > 0:02:59Very lovely, those kids.
0:02:59 > 0:03:03Rees asks, what was your favourite trip?
0:03:03 > 0:03:05Weston-Super-Mare.
0:03:05 > 0:03:07Weston-Super-Mare?
0:03:07 > 0:03:11Up till now, it's just been letters, but just before Christmas,
0:03:11 > 0:03:14they will meet in real life and be able to share
0:03:14 > 0:03:20their stories face-to-face.
0:03:20 > 0:03:25There's loads of junk floating around in space and it can be a big
0:03:25 > 0:03:28problem for spacecrafts and satellites up there.
0:03:28 > 0:03:30Here's Hayley.
0:03:30 > 0:03:33There are around half a million pieces of junk in space.
0:03:33 > 0:03:36Bits of old rocket, satellites that don't work
0:03:36 > 0:03:38and even things astronauts have dropped.
0:03:38 > 0:03:40Whoops!
0:03:40 > 0:03:44All that rubbish weighs around 7500 tonnes.
0:03:44 > 0:03:47That's more than the weight of 1000 elephants.
0:03:47 > 0:03:51And this space junk can do serious damage.
0:03:51 > 0:03:53Just a tiny fleck of paint caused this
0:03:53 > 0:03:56crack on the International Space Station.
0:03:56 > 0:03:58A European satellite that stopped working years ago is still
0:03:58 > 0:04:01orbiting around Earth.
0:04:01 > 0:04:04It is the size of a double-decker bus and
0:04:04 > 0:04:07could be a big problem for satellites in its path trying to do
0:04:07 > 0:04:11their own job.
0:04:11 > 0:04:13But the remove debris spacecraft could be the answer.
0:04:13 > 0:04:16Next year, a team of UK scientists will test out a harpoon
0:04:16 > 0:04:19and a net to grab floating space junk.
0:04:19 > 0:04:23The rubbish will then burn out as it gets dragged back towards Earth.
0:04:23 > 0:04:29Good luck with the cleaning!
0:04:29 > 0:04:33Next, to a pretty unusal way to board a plane.
0:04:33 > 0:04:40Vincent Reffet and Fred Fugen decided to enter a flying plane,
0:04:40 > 0:04:42by throwing themselves off Jungfrau Mountain in the Swiss Alps
0:04:42 > 0:04:46in a flying suit and jumping through the tiny doorway.
0:04:46 > 0:04:50Wow!
0:04:50 > 0:04:55Happy St Andrews day for all of you celebrating.
0:04:55 > 0:04:57That's all we have time for this afternoon, I'll be back
0:04:57 > 0:04:59bright and early tomorrow morning at 7.40am.
0:05:04 > 0:05:08BOTH: Hey, guys! We just wanted to say we love The Next Step
