:00:00. > :00:07.Afternoon, guys - Martin here with a 400 million mile space journey and
:00:08. > :00:15.what could be the biggest cat fan ever all coming up on Newsround.
:00:16. > :00:19.Let's start with the latest mission to Mars.
:00:20. > :00:21.This morning a new spacecraft entered
:00:22. > :00:24.the red planet's orbit as part of a project to test whether it could,
:00:25. > :00:41.It's a journey that has taken ten months but this morning, these were
:00:42. > :00:47.the scenes when the NASA spacecraft finally reached its test the
:00:48. > :00:51.nation, Maas. Since setting off last November, it has travelled more than
:00:52. > :00:58.400 million miles through space and with a final push, it entered the
:00:59. > :01:07.red planet 's orbit. The plan now is to circle the planet for a year as
:01:08. > :01:10.part of a plan to use study the atmosphere. Experts think this
:01:11. > :01:13.part of a plan to use study the what Mars looked like billions of
:01:14. > :01:18.years ago, very similar to Earth. Scientists hope that by studying
:01:19. > :01:21.their atmosphere, they can find out how it went from this to be dry and
:01:22. > :01:28.barren planet is his now. It's not the only craft looking at the
:01:29. > :01:32.planet. They are already exploring and digging below it to find out if
:01:33. > :01:38.there was ever life on Mars. All and digging below it to find out if
:01:39. > :01:44.this interest in the red planet is aimed at beginning another, bigger
:01:45. > :01:48.goal. All our mission is as up to enabling us to find out how humans
:01:49. > :01:53.would be able to go to Mars, survive for long periods of time, colonised
:01:54. > :02:01.the planet over time. That's in our future. It may be light years away
:02:02. > :02:02.but NASA hoped that one day there will be hope for humans out of this
:02:03. > :02:04.world. Edinburgh zoo, in Scotland,
:02:05. > :02:07.has confirmed it won?t be hearing the pitter patter
:02:08. > :02:09.of panda cub paws any time soon. Today they announced that Tian Tian,
:02:10. > :02:11.their giant female panda, Experts had hoped she might give
:02:12. > :02:16.birth to the first giant panda cub But the latest tests show
:02:17. > :02:20.that's not going to happen. The zoo say she is
:02:21. > :02:22.in good health though. And from one endangered species to
:02:23. > :02:25.another - and attempts to try and stop the falling numbers
:02:26. > :02:30.of one of the UK's rarest toads. We sent Ayshah on the hunt for one
:02:31. > :02:47.of nature's hardest to spot breeds. I have come here to this big reserve
:02:48. > :02:53.in Dumfries in the South of Scotland and I'm on the lookout for something
:02:54. > :02:58.which is hard to find, and natterjack toad. They usually live
:02:59. > :03:02.in salt marshes in small groups. This environment is unprintable and
:03:03. > :03:05.can leave the toads without much access to fresh water. Since the
:03:06. > :03:11.70s, their numbers have been falling. Experts think there are
:03:12. > :03:16.only 60 left in this part of Scotland. The best time to spot them
:03:17. > :03:23.is at night with one of these and one of these. I have a toad exposed
:03:24. > :03:24.here. Some toads can be poisonous so it's best to leave it to
:03:25. > :03:37.specialists. We have been searching for hours but
:03:38. > :03:43.we couldn't spot a single natterjack toad so why's it to find one? They
:03:44. > :03:47.need sand dunes, they don't hibernate in the winter and they dig
:03:48. > :03:55.a borough, it keeps them nice and warm. -- they go and hibernate. If
:03:56. > :04:01.they are found, there are measured and photographed on this information
:04:02. > :04:04.goes into a big database. Everybody has different fingerprints. The line
:04:05. > :04:09.on the back of the toad is different to every individual toad, and we
:04:10. > :04:14.have found some small toads that have emerged this year, we have
:04:15. > :04:17.pictures of them. The toads that are found will help scientists keep
:04:18. > :04:20.track of these endangered species. Now it's time for me to hop off.
:04:21. > :04:23.Well, sticking with nature, head over to the Newsround website
:04:24. > :04:28.to find out why spiders could be a bit bigger than usual this autumn.
:04:29. > :04:30.Loads of you have emailed in about your spidey sightings -
:04:31. > :04:33.So if you see any spiders, or webs, around your house,
:04:34. > :04:38.Be careful though, and make sure there's an adult with you if you do.
:04:39. > :04:41.Finally, if you think you're a bit of a cat lover -
:04:42. > :04:45.Silvana here, from Kent, has 50 feline friends living with her.
:04:46. > :04:50.She says their unconditional love is why she is so crazy about them.
:04:51. > :04:54.That's all from me - Newsround's back right here in
