0:00:02 > 0:00:04This is the Let's Go Club - but mini!
0:00:04 > 0:00:06Expect making, exploring,
0:00:06 > 0:00:08super-sizing, dancing,
0:00:08 > 0:00:11fact-finding and laughing.
0:00:11 > 0:00:13So, get ready for more fun
0:00:13 > 0:00:15from the Let's Go Club.
0:00:19 > 0:00:23Today, we're finding out all about space.
0:00:23 > 0:00:24Satellite,
0:00:24 > 0:00:26rocket flight,
0:00:26 > 0:00:27black hole,
0:00:27 > 0:00:29starry stroll,
0:00:29 > 0:00:30icy comet,
0:00:30 > 0:00:32earth orbit,
0:00:32 > 0:00:33space station,
0:00:33 > 0:00:35gravitation,
0:00:35 > 0:00:36UFO,
0:00:36 > 0:00:38blast off, go!
0:00:38 > 0:00:40Let's get to those facts.
0:00:41 > 0:00:42First up,
0:00:42 > 0:00:44astronauts cannot cry.
0:00:44 > 0:00:46Sad, but true.
0:00:46 > 0:00:50In space, there's no gravity to pull things down
0:00:50 > 0:00:53and that means that tears don't fall or flow -
0:00:53 > 0:00:55instead, they float
0:00:55 > 0:00:57like watery bubbles...
0:00:57 > 0:00:59or cling on to your face
0:00:59 > 0:01:02until little puddles form under your eyes.
0:01:02 > 0:01:05Has anyone got a tissue?
0:01:05 > 0:01:07Next, the footprints that astronauts
0:01:07 > 0:01:11left behind on the Moon will be there for ever
0:01:11 > 0:01:14and it isn't because they didn't wipe their feet.
0:01:14 > 0:01:16The Moon has no atmosphere
0:01:16 > 0:01:19and that means it doesn't have any weather, either.
0:01:19 > 0:01:21So, there's no wind or rain
0:01:21 > 0:01:24to blow and wash away the tracks.
0:01:24 > 0:01:28Next time, I'd suggest taking a brush.
0:01:28 > 0:01:32Next, space is full of rubbish
0:01:32 > 0:01:35and it's mostly because of us.
0:01:35 > 0:01:38Ever since we started exploring space,
0:01:38 > 0:01:40- we've been leaving things behind. - One!
0:01:40 > 0:01:42Bits of old rocket,
0:01:42 > 0:01:43an astronaut's glove,
0:01:43 > 0:01:45a camera,
0:01:45 > 0:01:46tools
0:01:46 > 0:01:47and a toothbrush.
0:01:47 > 0:01:50They're all floating around up there somewhere.
0:01:50 > 0:01:53Maybe the next mission to blast off
0:01:53 > 0:01:56should take some bin bags and do some tidying up.
0:01:56 > 0:01:57And finally,
0:01:57 > 0:02:01there are no green stars in space.
0:02:01 > 0:02:04The colour of a star depends on how hot it is
0:02:04 > 0:02:07with all that gas burning inside.
0:02:07 > 0:02:09Red stars are the coldest,
0:02:09 > 0:02:12blue stars are the hottest
0:02:12 > 0:02:14and the star you know very well,
0:02:14 > 0:02:16the Sun, is yellow
0:02:16 > 0:02:19with a temperature that's somewhere in the middle.
0:02:19 > 0:02:23Just the right amount of heat to keep us toasty warm.
0:02:23 > 0:02:25Fact.
0:02:26 > 0:02:29You can be part of the Let's Go Club, too.
0:02:29 > 0:02:32Grab a grown-up and head to the CBeebies website.
0:02:32 > 0:02:36Remember, we're the club that never closes.
