:00:00. > :00:09.This is Newsround. It's Friday the 4th of April. I'm Ricky. Coming up
:00:10. > :00:13.in the next five minutes: Scientists think that an icy moon in the rings
:00:14. > :00:18.of Saturn is a likely candidate for supporting life.
:00:19. > :00:20.And, could we be back on Panda watch soon? Edinburgh's two giant pandas
:00:21. > :00:28.could be ready to mate once again. First: It connects together most of
:00:29. > :00:31.the south west of England. But, for the past two months, the railway
:00:32. > :00:34.line in Dawlish has looked more like a broken roller-coaster. After it
:00:35. > :00:38.was destroyed in January's winter storms, the people living in large
:00:39. > :00:41.parts of Cornwall and Devon have had to find other ways of getting
:00:42. > :00:50.around. But, today, the line reopens, and Ayshah is there for us.
:00:51. > :00:59.Here's Nel with a reminder of what happened. For 150 years, this rail
:01:00. > :01:05.line has survived but ever the sea has thrown at it. The winter storms
:01:06. > :01:10.proved too much and in February waves punched a huge hole in the
:01:11. > :01:14.line leaving the tracks suspended in mid air. The waves have taken away
:01:15. > :01:21.the ground work that used to be under the track, leaving the famous
:01:22. > :01:27.railway track hanging there. Since then, Network Rail has spent ?50
:01:28. > :01:31.million repairing it. The operation has been enormous, involving
:01:32. > :01:36.hundreds of engineers working 24 hours a day for eight weeks. They
:01:37. > :01:41.have been known as the Orange army dressed in their fluorescent gear.
:01:42. > :01:49.It is clear as to why so much work has gone into repairs. It is the
:01:50. > :01:54.mainland -- mainline and has cost the economy ?2 million a day. As the
:01:55. > :01:56.holidays begin, large parts of the South West are now open for
:01:57. > :02:12.business. She's the author who inspired CBBC's
:02:13. > :02:15.Tracy Beaker and the Dumping Ground. And, later this year, Jacqueline
:02:16. > :02:18.Wilson will release her 100th book. Tomorrow, an exhibition opens at the
:02:19. > :02:20.V Museum of Childhood to celebrate the former children's laureate. It
:02:21. > :02:23.features a recreation of Jacqueline's childhood bedroom. And
:02:24. > :02:26.she told the BBC how different life was like back when she was growing
:02:27. > :02:29.up. We didn't even have a television in
:02:30. > :02:33.our living room until I was about nine. No, children didn't have
:02:34. > :02:36.anything then. They had books and I loved my books. It is strange,
:02:37. > :02:41.sitting here, and seeing a bed very much like the one I had. The exact
:02:42. > :02:42.paintings I had on the wall. It is what everybody thinks about,
:02:43. > :02:54.returning home to your childhood. Space time, and Saturn's icy moon,
:02:55. > :02:57.known as Enceladus, could be home to life, according to Nasa scientists.
:02:58. > :02:59.They've been looking at new data that's come back from the Cassini
:03:00. > :03:06.probe, shooting through the solar system, scouting for signs of life.
:03:07. > :03:09.It found evidence that suggests a huge volume of water underneath the
:03:10. > :03:13.ice on the moon, which supports the idea that the frozen world could be
:03:14. > :03:17.one of the most likely places in our solar system to support life. The
:03:18. > :03:19.next step is to see whether we could get a spacecraft to go and have an
:03:20. > :03:31.even closer look. Check out these pictures of a
:03:32. > :03:34.satellite that was launched yesterday as part of a European
:03:35. > :03:37.project to gather more images of Earth. The Sentinel-1A spacecraft is
:03:38. > :03:40.the first of a number of satellites being launched to gather more
:03:41. > :03:43.information about our planet. It's hoped this long-term programme will
:03:44. > :03:45.help scientists keep track of changes to the Earth's environment,
:03:46. > :03:50.and better understand the human impact on it.
:03:51. > :03:55.Tennis. And Andy Murray is in action later today, when Great Britain
:03:56. > :03:59.takes on Italy in the Davis Cup quarterfinals. The Scot spent most
:04:00. > :04:02.of yesterday in bed with a virus, but did manage to train for 50
:04:03. > :04:04.minutes last night. Team-mate James Ward is up against Fabio Fognini in
:04:05. > :04:15.the first match this morning. We could soon be back on panda
:04:16. > :04:18.watch. Edinburgh Zoo's two giant pandas could be ready to mate within
:04:19. > :04:22.the next week or two, according to their keepers. Tian Tian and Yang
:04:23. > :04:25.Guang arrived in Scotland last year, on loan from China. After a lot of
:04:26. > :04:29.waiting around, there was nothing. Pandas are famous for not being good
:04:30. > :04:30.at breeding. The zoo is hopeful that there'll be more success this time
:04:31. > :04:40.around. The trailer for the Shaun The Sheep
:04:41. > :04:44.movie has been released by its makers, Aardman, who also do Wallace
:04:45. > :04:47.and Gromit. The movie follows the sheep as he swaps the farm, and
:04:48. > :04:51.heads to the city for a new adventure. It hits cinemas around
:04:52. > :04:53.the world in about a year. But you can see the trailer on the Newsround
:04:54. > :04:56.website right now.
