0:00:03 > 0:00:04Hi, Ricky here.
0:00:04 > 0:00:06This is your Saturday lunchtime Newsround.
0:00:06 > 0:00:09Here's what we've got for you.
0:00:09 > 0:00:10There's no greater pressure
0:00:10 > 0:00:13than the pressure an anthlete puts on themselves.
0:00:13 > 0:00:15Gold medalist Amy Williams tells Newsround
0:00:15 > 0:00:20what it's like to be a Team GB athelete!
0:00:20 > 0:00:27Plus the cutest thing you'll see today.
0:00:33 > 0:00:35First up, news from PyeongChang,
0:00:35 > 0:00:37where the Winter Olympics are underway.
0:00:37 > 0:00:41Team GB medal hopeful Elise Christie took to the ice this morning,
0:00:41 > 0:00:45in the 500 metre short track speed skating heats.
0:00:45 > 0:00:48And it was a great start for Elise in her first race
0:00:48 > 0:00:50of the games so far.
0:00:50 > 0:00:55She beat opponents from China, Korea and France to win the heat,
0:00:55 > 0:00:57and she set a brand new Olympic record while doing it.
0:00:57 > 0:01:02She's now through to the quarter finals.
0:01:02 > 0:01:05Next up, imagine how nervous Elise must have been on that start line.
0:01:05 > 0:01:08Well, earlier this morning, I caught up with Amy Williams,
0:01:08 > 0:01:11who won gold at the Winter Games in Vancouvereight years ago.
0:01:11 > 0:01:17She knows exactly how this year's athletes are feeling.
0:01:17 > 0:01:20Every athlete knows that they want to win a medal,
0:01:20 > 0:01:22because they want to stand on the podium.
0:01:22 > 0:01:28They've done all the years of hard work.
0:01:28 > 0:01:30And then each sport has to say which medals,
0:01:30 > 0:01:32and how many they will target for.
0:01:32 > 0:01:34And then there's that pressure on the whole team.
0:01:34 > 0:01:35But there's still no greater pressure
0:01:35 > 0:01:37than the pressure that an athlete puts on themselves.
0:01:37 > 0:01:40But when you know that lots of funding has gone
0:01:40 > 0:01:42into your sport and you have to bring home a medal,
0:01:42 > 0:01:43it's really hard.
0:01:43 > 0:01:46So, psychologically in your head, you have to kind of think on
0:01:46 > 0:01:51that and then park it, stand on the start line, perform
0:01:51 > 0:01:54and hope that your result happens.
0:01:54 > 0:01:57Now, in 2010, you got gold in the women's skeleton,
0:01:57 > 0:01:59and you kind of became this star overnight -
0:01:59 > 0:02:01all this attention on you.
0:02:01 > 0:02:04What's it like when you win a medal at an Olympics?
0:02:04 > 0:02:06What is that feeling like?
0:02:06 > 0:02:09It's funny, because I knew my training times were really good,
0:02:09 > 0:02:11I knew I could win a medal,
0:02:11 > 0:02:13but I never allowed myself to think about it.
0:02:13 > 0:02:16And then it happens, and all of a sudden you're
0:02:16 > 0:02:19going through the media zone which is the area that you have to
0:02:19 > 0:02:20walk through with the world's press.
0:02:20 > 0:02:22You got Clare Balding interviewing you,
0:02:22 > 0:02:25you've got, you know, German TV all excited,
0:02:25 > 0:02:28whoever it might be.
0:02:28 > 0:02:31And then your land home and you don't realise
0:02:31 > 0:02:34what's been going on back home when you're in a foreign country.
0:02:34 > 0:02:36You get on that flight, and I specifically still remember,
0:02:36 > 0:02:38the first time I'd been in first-class,
0:02:38 > 0:02:40seat number 1A - amazing!
0:02:40 > 0:02:43But I look back now and it was eight years ago,
0:02:43 > 0:02:46and it's like this blur, as if it never happened.
0:02:46 > 0:02:49When I watch that girl in all the replays and clips,
0:02:49 > 0:02:50was that girl me?
0:02:50 > 0:02:51Wow.
0:02:51 > 0:02:52It's a really strange...
0:02:52 > 0:02:53Like an out of body experience?
0:02:53 > 0:02:54An out of body experience.
0:02:54 > 0:02:57But I wish I could find a genie in a lamp.
0:02:57 > 0:03:01I wish I could go back and relive it all again, and write a diary,
0:03:01 > 0:03:03because you think you're going to remember all of it
0:03:03 > 0:03:04and you don't.
0:03:04 > 0:03:05You remember little snippets.
0:03:05 > 0:03:08Well, listen, thank you so much for coming in to chat to Newsround,
0:03:08 > 0:03:11and hopefully over the next few weeks we'll see those medals
0:03:11 > 0:03:13kind of go up and up.
0:03:13 > 0:03:14Fingers crossed.
0:03:14 > 0:03:15I hope so.
0:03:15 > 0:03:17Fingers crossed.
0:03:17 > 0:03:19Now, here's a sport that you won't be seeing played
0:03:19 > 0:03:22over in PyeongChang - ice cricket!
0:03:22 > 0:03:25The match in Switzerland was played on a fake grass
0:03:25 > 0:03:29carpet laid over the snow and with a bright orange ball.
0:03:29 > 0:03:31Cricketing legends from around the world joined forces to take part
0:03:31 > 0:03:34in the chilly but friendly games.
0:03:34 > 0:03:40Looks like a good excuse for a hot chocolate if you ask me.
0:03:40 > 0:03:45Next, some big news in the world of space travel.
0:03:45 > 0:03:47The most powerful rocket in the world, the Falcon Heavy,
0:03:47 > 0:03:49was successfully launched into space on Tuesday night.
0:03:49 > 0:03:52Houston - run VT!
0:03:52 > 0:03:56Five, four, three, two, one...
0:03:56 > 0:03:59Blastoff!
0:03:59 > 0:04:01It's taken seven years but, boys and girls,
0:04:01 > 0:04:04that is what you call a successful launch of the most powerful
0:04:04 > 0:04:06rocket ever built.
0:04:06 > 0:04:09The Falcon Heavy is the brainchild of SpaceX,
0:04:09 > 0:04:12the company run by South African Elon musk.
0:04:12 > 0:04:13Never heard of him?
0:04:13 > 0:04:16Well, it's rumoured that Robert Downey Junior based
0:04:16 > 0:04:20the character of Tony Stark, aka Iron Man, on him.
0:04:20 > 0:04:24It kind of gives you an idea about the type of guy he is.
0:04:24 > 0:04:26Back to the rocket.
0:04:26 > 0:04:29It used 27 separate engines to launch it into space.
0:04:29 > 0:04:34That's around the same power as 18 Boeing 747 aeroplanes taking off,
0:04:34 > 0:04:38and twice as powerful as any other rocket in use at the minute.
0:04:38 > 0:04:41It means the Falcon Heavy can carry twice as much into space,
0:04:41 > 0:04:4364 tonnes, to be exact.
0:04:43 > 0:04:46That's basically five double-decker buses.
0:04:46 > 0:04:50It opens up the possibility for astronauts to travel further,
0:04:50 > 0:04:54and for bigger robots to be sent to planets like Mars.
0:04:54 > 0:04:57On top of that, the boosters that the Falcon uses
0:04:57 > 0:04:59to power it into space are reusable.
0:04:59 > 0:05:01Once detached from the main body of the craft,
0:05:01 > 0:05:05they should fly themselves back to Earth.
0:05:05 > 0:05:07Now that is cool.
0:05:07 > 0:05:11So who was lucky enough to be on the first flight?
0:05:11 > 0:05:13Well, no humans, unfortunately.
0:05:13 > 0:05:15You see, a lot of test flights can go wrong.
0:05:15 > 0:05:19But that's not to say the spaceship was empty.
0:05:19 > 0:05:22Bring forth Starman!
0:05:22 > 0:05:24Yeah, that's a dummy riding a cherry red car to Mars,
0:05:24 > 0:05:29with the radio on of course!
0:05:29 > 0:05:30Finally, you won't see anything cuter
0:05:30 > 0:05:32than these tiny bear cubs today.
0:05:32 > 0:05:34They were found abandoned in a cardboard box
0:05:34 > 0:05:38by these people living in a remote part of Moscow, in Russia.
0:05:38 > 0:05:41They took the baby bears in and looked after them,
0:05:41 > 0:05:44before handing them over to animal welfare experts.
0:05:44 > 0:05:47The orphaned cubs are being fed with baby food and warm milk.
0:05:47 > 0:05:50It's hoped that they will be released back into the wild
0:05:50 > 0:05:53when they're older.
0:05:54 > 0:05:57We're back in an hour.
