0:00:04 > 0:00:08These Stargazers can't wait to get exploring at Mission Control
0:00:08 > 0:00:09and neither can I.
0:00:09 > 0:00:13And we'd love you to come space exploring with us.
0:00:13 > 0:00:16Stars and planets and so much more.
0:00:16 > 0:00:20Countdown to launch, mission explore!
0:00:20 > 0:00:23- ALL:- Five, four,
0:00:23 > 0:00:28three, two, one, lift-off!
0:00:33 > 0:00:40# We're on a mission to explore the wonders of the stars above us all
0:00:40 > 0:00:43# Planets, stars and more They're for us to find
0:00:43 > 0:00:45# When we look up high, here we go
0:00:47 > 0:00:50# We're going stargazing
0:00:50 > 0:00:54# Gaze at stars shining bright
0:00:54 > 0:00:57# We're going stargazing
0:00:57 > 0:01:01# Spot a zooming satellite
0:01:01 > 0:01:04# We're going stargazing
0:01:04 > 0:01:07# Glimpse the moon and the planets above
0:01:07 > 0:01:11# We're going stargazing
0:01:11 > 0:01:17# So just look up Look up, look up. #
0:01:32 > 0:01:34Mission explore - go!
0:01:34 > 0:01:38Excellent work, Stargazers. Welcome to Mission Control.
0:01:38 > 0:01:41- Thanks, Maggie. - Now, first things first.
0:01:41 > 0:01:45- Who's going to help me download the latest mission data?- Me.
0:01:45 > 0:01:49Can you remember Maggie's mini-mission from last night?
0:01:49 > 0:01:53Well, she asked us to spot bright things in the night sky.
0:01:53 > 0:01:55Let's activate the map.
0:01:55 > 0:01:56Map - go.
0:01:59 > 0:02:01Mission data downloading.
0:02:01 > 0:02:05The brightest thing I can see tonight is the moon.
0:02:05 > 0:02:07It's through the trees.
0:02:09 > 0:02:16I counted ten stars and they were all really bright.
0:02:18 > 0:02:23I can see a big star and it's really bright and I think it must be
0:02:23 > 0:02:24Venus or something.
0:02:24 > 0:02:28Brian Cox, here, with an update for Mission Control.
0:02:28 > 0:02:32One of my favourite bright things in the sky is the planet Jupiter.
0:02:32 > 0:02:38It's a giant ball of gas that reflects the sun's light brightly
0:02:38 > 0:02:39and it's massive.
0:02:42 > 0:02:43Download complete.
0:02:45 > 0:02:48Well done, Stargazers.
0:02:48 > 0:02:50Come in, Mission Control.
0:02:50 > 0:02:52Oh! It's Robert The Robot.
0:02:52 > 0:02:54Sky Station calling.
0:02:54 > 0:02:58It was cloudy at the Sky Station last night,
0:02:58 > 0:03:02but I've still managed to collect some mission data for you.
0:03:02 > 0:03:04Thanks, Robert. Downloading data.
0:03:06 > 0:03:09We're here, nice and cosy, in the Sky Station,
0:03:09 > 0:03:12cos it's rather cloudy and wet outside.
0:03:12 > 0:03:16What bright things do you think are hiding behind the clouds?
0:03:16 > 0:03:20- Stars.- That's right, stars. What else?- Planets.
0:03:20 > 0:03:22The moon!
0:03:22 > 0:03:26It's like all the bright things are playing hide and seek with us
0:03:26 > 0:03:27behind the clouds.
0:03:27 > 0:03:31- Download complete.- Well done, Robert. Well done, Stargazers.
0:03:31 > 0:03:35You managed to get mission data, even though it was cloudy.
0:03:35 > 0:03:38Who's ready for another mission from Maggie?
0:03:38 > 0:03:39- ALL:- Me!
0:03:39 > 0:03:44Excellent. Well, today's mission is to find out about this.
0:03:44 > 0:03:47- Mars.- Mars.- Mars. Yes.
0:03:47 > 0:03:51Your mission is to find out what it's like on the planet Mars.
0:03:51 > 0:03:54Now, this picture was taken by a telescope in space.
0:03:54 > 0:03:58- Now, what colour is the planet? - ALL:- Red.
0:03:58 > 0:04:00Now, can anyone tell me what this is?
0:04:02 > 0:04:04- It looks like a truck.- A robot.
0:04:04 > 0:04:09This is a robot called Curiosity and it's busy exploring Mars.
0:04:09 > 0:04:13And it looks like Curiosity is taking a selfie.
0:04:13 > 0:04:16In fact, let's take one right now, everybody.
0:04:16 > 0:04:18- Oh, yeah!- After three, say, "Mars."
0:04:18 > 0:04:21Are you ready? One, two, three...
0:04:21 > 0:04:23- ALL:- Mars!
0:04:25 > 0:04:29Now, that's exactly what Curiosity was doing, Chris.
0:04:29 > 0:04:33- It was taking a selfie.- Now, robots like this are called rovers.
0:04:33 > 0:04:37Rovers, like Curiosity, are blasted off to Mars on rockets.
0:04:37 > 0:04:40Then they trundle over the planet's surface.
0:04:40 > 0:04:44They take photographs, collect rocks and even do experiments on Mars.
0:04:44 > 0:04:46This gives space scientists on Earth
0:04:46 > 0:04:49lots of clues about what Mars is like.
0:04:49 > 0:04:52I know a robot who'd make a brilliant rover.
0:04:52 > 0:04:54Robert The Robot.
0:04:54 > 0:04:57Let's see if Robert can help us collect some clues,
0:04:57 > 0:04:59to find out more about Mars.
0:04:59 > 0:05:02Sky station, go.
0:05:05 > 0:05:08Copy that, Mission Control.
0:05:08 > 0:05:09Galloping galaxies!
0:05:09 > 0:05:13I'm going to be a rover, just like Curiosity on Mars.
0:05:13 > 0:05:16Yes, brave, fearless Robert.
0:05:16 > 0:05:20Robert the Rover is ready for anything.
0:05:20 > 0:05:24- Oh, hello.- Come on, Robert. We need to launch into outer space.
0:05:24 > 0:05:26- Let's go. - Oh, right, all right, let's go.
0:05:26 > 0:05:29All right, into outer space. Lovely!
0:05:29 > 0:05:32Right, when I said, "Lovely," I really didn't think
0:05:32 > 0:05:35this is what you meant. It's really quite high.
0:05:35 > 0:05:37- Are you nervous, Hayden?- No.
0:05:37 > 0:05:40- Prepare for launch. - Launch? What do you mean, launch?
0:05:40 > 0:05:42Three, two, one, lift-off!
0:05:42 > 0:05:45I immediately regret this decision!
0:05:45 > 0:05:48Oh! Oh, actually...
0:05:48 > 0:05:50Oh, I quite like it.
0:05:50 > 0:05:51In fact, I love it!
0:05:51 > 0:05:53Oh, this is amazing!
0:05:54 > 0:05:56Oh, Hayden, we're in orbit,
0:05:56 > 0:06:00just like the rocket that took Curiosity to Mars.
0:06:06 > 0:06:10Right, Stargazers, get ready for a rover selfie.
0:06:10 > 0:06:12All right, everybody say, "Mars."
0:06:12 > 0:06:17- One, two, three... - ALL:- Mars.
0:06:17 > 0:06:19Lovely. Now, my friend Lucy, here,
0:06:19 > 0:06:23is giving us a lift on this rather splendid buggy.
0:06:23 > 0:06:26It's about the same size as Curiosity, the rover.
0:06:26 > 0:06:29So, let's get to work and look for some rocks.
0:06:29 > 0:06:31Over to you, Lucy.
0:06:31 > 0:06:34Right, what can we see, everybody? What can we see?
0:06:36 > 0:06:39- Trees.- Yes, we can see trees.
0:06:39 > 0:06:42- Moss.- Moss, yes.- Water.
0:06:42 > 0:06:46Do you know what? This is what it must be like on the surface of Mars
0:06:46 > 0:06:47for Curiosity, the rover.
0:06:47 > 0:06:52You know? Trundling over the surface, looking for rocks.
0:06:52 > 0:06:54- Any rocks? - There could be rocks in there.
0:06:54 > 0:06:57- Can you see some? - Can you see a rock?- Yeah, look!
0:06:57 > 0:07:01- Oh, look there! Oh, rocks! - I see rocks.- Yes, rocks!
0:07:01 > 0:07:03Right, leave this to me.
0:07:03 > 0:07:06Ooh. Right. Here we go.
0:07:06 > 0:07:09Mission Control is going to be thrilled. Right.
0:07:26 > 0:07:28CAMERA BLEEPS HE CHUCKLES
0:07:28 > 0:07:29Very good.
0:07:29 > 0:07:32Right, here we go. We have rocks!
0:07:32 > 0:07:33I have rocks!
0:07:33 > 0:07:36Oh, this is wonderful. Well done, everybody.
0:07:37 > 0:07:43Right. Stargazers, shall we send these rocks to Mission Control?
0:07:43 > 0:07:44- Yes.- Yes.- Excellent.
0:07:44 > 0:07:46Amy, you know what to do.
0:07:46 > 0:07:50- Over to you, Hayden. - Sky station sending clues now.
0:07:51 > 0:07:53ALL: Hurray!
0:07:53 > 0:07:56Back to you, Mission Control.
0:07:58 > 0:07:59The rocks are coming.
0:08:02 > 0:08:03Excellent. They're here.
0:08:05 > 0:08:07Now, who'd like to hold one?
0:08:07 > 0:08:09STARGAZERS: Me! Me!
0:08:09 > 0:08:11One for you, one for you.
0:08:11 > 0:08:13How do these rocks feel?
0:08:13 > 0:08:16- Smooth. - It looks like a round oval.
0:08:16 > 0:08:17BLEEP
0:08:17 > 0:08:20Ooh! I must have forgotten to turn this off
0:08:20 > 0:08:22when we took our selfie earlier. Ooh, look!
0:08:22 > 0:08:25It's a photo from Robert.
0:08:25 > 0:08:28Now look closely, because there's a clue here,
0:08:28 > 0:08:31as to what could have made the rocks smooth.
0:08:31 > 0:08:33Can anyone see anything in the picture
0:08:33 > 0:08:36that might make the rocks smooth?
0:08:36 > 0:08:39- The water.- In the river?
0:08:39 > 0:08:43That's right. Now, once upon a time your rocks were a bit like these.
0:08:43 > 0:08:45They had hard, jaggedy edges.
0:08:45 > 0:08:47But when water picks up the rocks,
0:08:47 > 0:08:51they tumble against each other, and what do you think happens?
0:08:51 > 0:08:54- It gets smoother? - You're absolutely right, Norr.
0:08:54 > 0:08:57As the rocks have tumbled against each other in the river,
0:08:57 > 0:09:00they've got smoother and rounder.
0:09:01 > 0:09:04Now, who would like to see a picture of Mars?
0:09:04 > 0:09:06ALL: Me!
0:09:07 > 0:09:11This is a picture taken by the Curiosity rover
0:09:11 > 0:09:12as it trundled across Mars.
0:09:12 > 0:09:15Now, what can we see in this picture?
0:09:15 > 0:09:17It's all full with the rocks.
0:09:17 > 0:09:20How do they look? Are they rough or smooth?
0:09:20 > 0:09:22STARGAZERS: Smooth.
0:09:23 > 0:09:26Well, these pictures are really similar, aren't they, Maggie?
0:09:27 > 0:09:29Yes, they are.
0:09:29 > 0:09:34Now, has anyone got any idea what made these rocks smooth on Mars?
0:09:34 > 0:09:37In this picture, the water made it smooth.
0:09:37 > 0:09:41And we know these rocks were made by tumbling around in water.
0:09:41 > 0:09:44So it might be possible these rocks were made
0:09:44 > 0:09:46by tumbling around in water, too.
0:09:46 > 0:09:48That's really interesting, Stargazers,
0:09:48 > 0:09:51cos this is a picture of an old riverbed on Mars.
0:09:51 > 0:09:55Cos a long, long, long time ago, there were lots of rivers on Mars,
0:09:55 > 0:09:58- and lots of rivers mean lots of... - ALL: Water!
0:09:59 > 0:10:03Well, that's fantastic exploring, Stargazers.
0:10:03 > 0:10:06Thanks to rovers like Curiosity, and Robert,
0:10:06 > 0:10:11we've discovered that there was once water on Mars,
0:10:11 > 0:10:13flowing in rivers and streams.
0:10:19 > 0:10:22Oh, look! It's getting dark out there.
0:10:22 > 0:10:25We might be able to spot Mars very soon.
0:10:32 > 0:10:35Let's all look up and see if we can spot Mars.
0:10:37 > 0:10:40- It's cloudy. - Oh, you're right, it is cloudy.
0:10:41 > 0:10:45If it wasn't cloudy, Maggie, how could we look for Mars?
0:10:45 > 0:10:50What you need to look for is an orangey-red dot amongst the stars.
0:10:51 > 0:10:55So you can actually see Mars with just your eyes?
0:10:55 > 0:10:58It's brilliant! And if you look through a telescope,
0:10:58 > 0:11:00you can see even more detail on Mars.
0:11:00 > 0:11:03Let's see what the telescope's seeing.
0:11:04 > 0:11:07Unfortunately, it's still too cloudy to see Mars.
0:11:07 > 0:11:09Oh, but if it wasn't cloudy, Maggie,
0:11:09 > 0:11:12what would we see through the telescope?
0:11:12 > 0:11:16If it was a clear night, we'd see Mars as a little red disc,
0:11:16 > 0:11:19but on top of that we'd see some of the detail over its surface.
0:11:19 > 0:11:24So, the telescope takes a closer look at Mars, but the rovers,
0:11:24 > 0:11:26like Curiosity, are even closer.
0:11:26 > 0:11:29They're actually on the planet's surface.
0:11:29 > 0:11:33So can you remember what we saw in the picture that Curiosity took?
0:11:33 > 0:11:34- Rocks.- Some rocks.
0:11:34 > 0:11:36Dried riverbeds.
0:11:36 > 0:11:38That is excellent work, Stargazers.
0:11:38 > 0:11:40Mission complete.
0:11:40 > 0:11:41Thumbs up from me.
0:11:41 > 0:11:43And it's a thumbs up from me.
0:11:43 > 0:11:46CHEERING
0:11:46 > 0:11:50Red Mars is a beautiful sight, shining amongst the stars.
0:11:50 > 0:11:54Now let's go and get cosy, ready for tonight's Starlight Story.
0:12:03 > 0:12:08Mars-red blankets, Stargazers.
0:12:08 > 0:12:10- Are they nice and cosy? STARGAZERS:- Yes.
0:12:10 > 0:12:12Oh, that's good.
0:12:12 > 0:12:14Now, what's the sky doing now?
0:12:15 > 0:12:16It's cloudy.
0:12:18 > 0:12:20But if we could blow the clouds away,
0:12:20 > 0:12:23what stars would come out to play?
0:12:23 > 0:12:25Up in the sky, above the clouds,
0:12:25 > 0:12:28is a constellation called Auriga, the charioteer.
0:12:28 > 0:12:32To find him you need to look for a really bright star
0:12:32 > 0:12:34with three fainter stars nearby.
0:12:34 > 0:12:37Now, the three faint stars make up his...
0:12:37 > 0:12:38STARGAZERS: Nose.
0:12:38 > 0:12:43Another three stars, in the shape of a triangle, make up his pointy...
0:12:43 > 0:12:44STARGAZERS: Hat!
0:12:44 > 0:12:50And I think Auriga the charioteer is ready for his Starlight Story.
0:12:50 > 0:12:54Auriga the charioteer wished to race on Mars.
0:12:54 > 0:12:57So off he set to the starting line,
0:12:57 > 0:13:00where he met some speedy cars.
0:13:00 > 0:13:03Now, Auriga's chariot was rather rickety,
0:13:03 > 0:13:05with wheels that were beginning to rust,
0:13:05 > 0:13:08so when the lights turned from red to green,
0:13:08 > 0:13:10the cars, they left him for dust!
0:13:11 > 0:13:15Around giant craters, the cars raced ahead.
0:13:15 > 0:13:19Then, Auriga just trundled, where the others had sped.
0:13:19 > 0:13:23Whizzing down riverbeds, the cars raced on.
0:13:23 > 0:13:26Auriga gave chase, but something was wrong!
0:13:27 > 0:13:30His wheel flew off and he came to a stop,
0:13:30 > 0:13:34just as he reached some giant red rocks.
0:13:35 > 0:13:38Auriga then noticed the cars had stopped, too.
0:13:38 > 0:13:42The rocks were so big they couldn't get through.
0:13:42 > 0:13:45The race couldn't come to an early end,
0:13:45 > 0:13:48so Auriga called for help from a friend.
0:13:49 > 0:13:52Curiosity, the rover, picked everyone up,
0:13:52 > 0:13:55and trundled them over the giant red rocks.
0:13:57 > 0:14:00Then, all together, and at the same time,
0:14:00 > 0:14:04the racers crossed over the finishing line!
0:14:12 > 0:14:16Thank you for helping us explore the Red Planet, Mars, tonight, Maggie.
0:14:16 > 0:14:18My pleasure.
0:14:18 > 0:14:21Stargazers, your mini-mission tonight
0:14:21 > 0:14:25is to see what colours you can spot in the night sky.
0:14:25 > 0:14:29Why not draw a picture of all the different colours you can spot
0:14:29 > 0:14:30in the night sky?
0:14:30 > 0:14:32You could even use Make A Picture,
0:14:32 > 0:14:34on the CBeebies website.
0:14:34 > 0:14:38We'll see you tomorrow for more stargazing.
0:14:38 > 0:14:42- From all of us, goodbye!- Goodbye! - STARGAZERS:- Goodbye!
