Hi guys. Live with the Newsround with amazing stuff. On the way: | :00:00. | :00:15. | |
Behind the scenes of Dr Who's 5th anniversary show. The robot that | :00:16. | :00:22. | |
herds cattle. This is Newsround. -- 5th anniversary show. | :00:23. | :00:28. | |
First to Mars. We know it as the Red Planet. Scientists think it could | :00:29. | :00:34. | |
once have been more like earth. In the next couple of hours NASA will | :00:35. | :00:39. | |
launch Maven, with I will try and find out what the planet used to be | :00:40. | :00:41. | |
like and why everything changed. This is what scientists thing Mars | :00:42. | :00:53. | |
could have looked like during the first one billion years of its | :00:54. | :00:57. | |
existence. There are clouds, lakes filled with water and it is believed | :00:58. | :01:04. | |
the planet had a thick protective atmospheric layer. In fact, it all | :01:05. | :01:08. | |
looks a bit like earth. Something happened which changed the planet | :01:09. | :01:13. | |
into the dusty, red one we recognise today. Water was abundant. On early | :01:14. | :01:20. | |
Mars the environment was something capable of supporting water. Today, | :01:21. | :01:24. | |
we see a cold, dry planet which is not able to support water. We want | :01:25. | :01:29. | |
to understand the reason for the change in the climate. So the early | :01:30. | :01:33. | |
atmosphere is thought to be like earth - with a layer of gases | :01:34. | :01:39. | |
helping to keep the temperature at the right level for life. We are | :01:40. | :01:44. | |
protected from radiation, which could damage us. Should we be | :01:45. | :01:47. | |
worried that what happened on Mars could happen here on earth? Mars is | :01:48. | :01:51. | |
much smaller than earth. Earth is big. We have a hot interior which | :01:52. | :01:57. | |
produces a magnet tick shield. I think the fact we are on such a big | :01:58. | :02:02. | |
planet and have a magnetic shield protecting the atmosphere, I think | :02:03. | :02:07. | |
we'll be fine. We will not lose our atmosphere any time soon like Mars | :02:08. | :02:10. | |
did four billion years ago. The probe, called Maven l take ten | :02:11. | :02:19. | |
months to get oh -- Maven will take ten months to get to Mars. It is | :02:20. | :02:23. | |
hoped it will solve the mystery of the Red Planet. Next, aid from the | :02:24. | :02:27. | |
UK has started to radio even the Philippines after the -- started to | :02:28. | :02:32. | |
reach the Philippines after the devastation of Typhoon Haiyan. A | :02:33. | :02:36. | |
plane left the East Midlands airport last night. HMS Daring arrived this | :02:37. | :02:41. | |
weekend, carrying a helicopter to help reach remote areas. Here are | :02:42. | :02:46. | |
some of the pictures it has taken. It is thought around 2.5 million | :02:47. | :02:51. | |
people need food aid. Head online to read our special diary, written by | :02:52. | :02:57. | |
an aid worker in the Philippines. Dr Who's big 5th anniversary -- 5th | :02:58. | :03:05. | |
anniversary show is on the way this weekend -- 50th anniversary show is | :03:06. | :03:10. | |
on the way this weekend. OK, so I have my hands on the recipe for a | :03:11. | :03:16. | |
perfect Dr Who episode. A handful of aliens - the scary, the better. Add | :03:17. | :03:22. | |
in a doctor or two, or even three! Simple! | :03:23. | :03:27. | |
We have been waiting for the 50th anniversary episode for ages. | :03:28. | :03:30. | |
Luckily we got our hands on some footage from behind the scenes. It | :03:31. | :03:37. | |
has been thrilling to make. I think there's something extraordinary | :03:38. | :03:40. | |
about the doctors meeting, which is gra just great fun -- - just great | :03:41. | :03:46. | |
fun to act in. There is a different Tardis, another | :03:47. | :03:51. | |
doctor and all that. It was completely different. Yet weirdly | :03:52. | :03:58. | |
familiar. Lovely to be back! The full details of the plot are | :03:59. | :04:03. | |
still under wraps. Expectations are high. | :04:04. | :04:07. | |
It promises to be an episode which celebrates the show's past as well | :04:08. | :04:16. | |
as looking to the future. Thanks for that. From Dr Who to Dr | :04:17. | :04:24. | |
You. We want your own tributes to Dr Who. Maybe you want to act out your | :04:25. | :04:31. | |
favourite scene. Here is some inspiration from seven-year-old | :04:32. | :04:38. | |
Dylan. Wlaefr your idea, head to the -- whatever your idea, head to the | :04:39. | :04:43. | |
website. We will play the best ones on Friday. Cattle herders could soon | :04:44. | :04:48. | |
be out of a job because Australian scientists have developed a robot to | :04:49. | :04:55. | |
round up cows. It has been a big hit with farmers. It collects | :04:56. | :05:00. | |
information about soil and fencing. That is all from me | :05:01. | :05:01. |
