0:00:51 > 0:00:56An incredible panoramic view sent from the surface of Mars has
0:00:56 > 0:00:58been made using images taken by the Curiosity rover.
0:00:58 > 0:01:00It shows the landscape of one of our closest planets.
0:01:00 > 0:01:03The robot has been exploring Mars, since it landed in 2012.
0:01:03 > 0:01:06One of its cameras took 16 photos, which were then put together
0:01:06 > 0:01:07to form this lovely view.
0:01:07 > 0:01:10NASA put a blue filter on the images, so we could see more
0:01:10 > 0:01:18than just Mars' signature red dust,
0:01:25 > 0:01:27Next up, ever dreamt of owning your very own football club?
0:01:27 > 0:01:29Well, that's been high up on David Beckham's bucket
0:01:29 > 0:01:31list for some time now.
0:01:31 > 0:01:33This week the ex-England captain announced plans to start up a brand
0:01:33 > 0:01:41new team all the way in the US, as Ricky's been finding out.
0:01:49 > 0:01:54David Beckham, one of the most famous footballers of all time. He
0:01:54 > 0:01:59used to play for Manchester United, scoring 61 Premier League goals for
0:01:59 > 0:02:05them. The former England captain played for his country 115 times. He
0:02:05 > 0:02:10joined some of the biggest clubs in the world like Real Madrid and AC
0:02:10 > 0:02:15Milan. More than ten years ago, David was snapped up by LA Galaxy,
0:02:15 > 0:02:21putting Major League Soccer on the map. He is married to Spice Girl
0:02:21 > 0:02:30Victoria Beckham. Together they have got four kids. David retired from
0:02:30 > 0:02:37football in 2013. At the time, he said his dream was to set up his own
0:02:37 > 0:02:41football club in the United States. That dream is now one step closer to
0:02:41 > 0:02:47becoming a reality.Today you make my dream come true.David is one of
0:02:47 > 0:02:52the owners of a new club based in Miami in Florida. The team has not
0:02:52 > 0:02:57got a name yet but plans to build a new 25,000 seater stadium have been
0:02:57 > 0:03:01given the green light.There were moments where I didn't think it
0:03:01 > 0:03:06would happen but I don't like to lose. And I don't give in very
0:03:06 > 0:03:11easily. I always believed in Miami and I always believed that this is
0:03:11 > 0:03:17where I wanted our team.And finally we are here. And he has got loads of
0:03:17 > 0:03:24support from all of these guys.If you need a striker, I am the guy.
0:03:24 > 0:03:29Congratulations on the new Miami team.
0:03:29 > 0:03:31Next, this one may get you feeling a little dizzy!
0:03:31 > 0:03:33It's the longest zip wire in the world.
0:03:33 > 0:03:37Check it out!
0:03:37 > 0:03:41Ready, steady, go!
0:03:41 > 0:03:48This zip wire is in the United Arab Emirates
0:03:48 > 0:03:52in the Middle East, ontop of a mountain.
0:03:52 > 0:03:57You can go super fast at 93 mph.
0:03:57 > 0:03:58It's 2.8km long -
0:03:58 > 0:03:59that's more than 28 football pitches.
0:03:59 > 0:04:01No wonder it's been given the Guinness world record
0:04:01 > 0:04:09for the longest zip wire in the world.
0:04:09 > 0:04:19That was amazing. I have never felt this way before.
0:04:19 > 0:04:22It takes around three mins to get to the end.
0:04:22 > 0:04:29Plenty time to enjoy this great view, if you're not scared that is!
0:04:29 > 0:04:32Last up, if we don't eat enough, we run out of energy pretty quickly,
0:04:32 > 0:04:35right?? That's because energy from food keeps us on the move.?But
0:04:35 > 0:04:42how much do you think a dolphin needs to munch?
0:04:45 > 0:04:48Feeling peckish? If you have had an active day, you might find your
0:04:48 > 0:04:53tummy rumbling. But while kids like you are recommended to munch around
0:04:53 > 0:04:571500 calories each day, you will never guess how much Dolphins need
0:04:57 > 0:05:03to eat. New research has found that they need up to a whopping 33,000
0:05:03 > 0:05:10calories a day. That is 60 plates of salmon to me and you. And amazingly,
0:05:10 > 0:05:17that amount was less than scientists had expected. The amount of food a
0:05:17 > 0:05:21dolphin needs varies depending on its size and whether it is resting,
0:05:21 > 0:05:25sleeping, diving or swimming. As well as the temperature of the
0:05:25 > 0:05:30ocean. Looks like this guy is working up an appetite. The study
0:05:30 > 0:05:33was carried out on Dolphins in Florida. They were captured for a
0:05:33 > 0:05:38short time in order to be monitored by scientists as they say the
0:05:38 > 0:05:42research will help with conservation. I hope all that fishes
0:05:42 > 0:05:47providing enough vitamins C, get it question mark never mind.
0:05:47 > 0:05:50That's it from me - Newsround's back tomorrow morning at 10.25.
0:05:50 > 0:05:51Have a lovely Saturday!
0:05:51 > 0:05:53Don't forget to head online for all the rest
0:05:53 > 0:06:00of the day's big stories!
