0:00:13 > 0:00:14Good morning.
0:00:14 > 0:00:19I'm Jenny, you're with Newsround.
0:00:19 > 0:00:21And after day one of the Rio Olympics,
0:00:21 > 0:00:23Britain already has a new world record in the swimming pool.
0:00:23 > 0:00:26But on an emotional first day, there was also disappointment
0:00:26 > 0:00:29as some of Team GB's brightest medal hopes failed in their bid
0:00:29 > 0:00:30for Olympic glory.
0:00:30 > 0:00:33Ricky is in Rio and has all the details.
0:00:33 > 0:00:34Hello from Rio, Ricky here.
0:00:34 > 0:00:35Day one is done and it has certainly thrown
0:00:36 > 0:00:37up a few surprises.
0:00:37 > 0:00:40It's been really hot today here in the Olympic Park,
0:00:40 > 0:00:43temperatures have reached more than 30 Celsius.
0:00:43 > 0:00:44It is so hot!
0:00:44 > 0:00:46But that's enough about that, let's talk about
0:00:46 > 0:00:47the sport.
0:00:47 > 0:00:49In the aquatic stadium, Adam Peaty, who is only
0:00:49 > 0:00:5521 years old, broke a world record.
0:00:55 > 0:00:56Yep, he swam his heart out
0:00:56 > 0:00:58in the men's 100 metres breaststroke.
0:00:58 > 0:01:01He's now qualified for the final.
0:01:01 > 0:01:03Tomorrow I'm hopefully going to move on a bit more.
0:01:03 > 0:01:06I feel there is something more in the tank
0:01:06 > 0:01:08but I want to save myself for that and
0:01:08 > 0:01:11hopefully, you know, get that investment of all that work
0:01:11 > 0:01:13I have done these past seven years.
0:01:13 > 0:01:14So many people congratulating me there.
0:01:14 > 0:01:18It is crazy and that is what it's all about, the Olympic experience.
0:01:18 > 0:01:20Adam's roommate here in Rio, James Guy, didn't pick up
0:01:20 > 0:01:22a medal in the 400 metres freestyle.
0:01:22 > 0:01:25Hannah Miley missed out on a medal in the women's individual
0:01:25 > 0:01:28400 metres medley.
0:01:28 > 0:01:30There was some disappointment for Team GB in the
0:01:30 > 0:01:33cycling as Chris Froome, who only recently won the Tour de France,
0:01:33 > 0:01:37was unable to pick up a medal here in Rio.
0:01:37 > 0:01:40And in judo, Team GB's Ashley McKenzie fought back
0:01:40 > 0:01:45the tears as he narrowly lost by a single point.
0:01:45 > 0:01:48Now, what I love about the Olympics is that it always throws up
0:01:48 > 0:01:49some amazing stories.
0:01:49 > 0:01:52Vietnam have never won a gold medal before but that has
0:01:52 > 0:01:54all changed.
0:01:54 > 0:01:57On Saturday, they won their first ever gold so imagine how
0:01:57 > 0:01:59they are celebrating in Vietnam right now.
0:01:59 > 0:02:01Plenty more drama to look forward to.
0:02:01 > 0:02:03We've got fencing, hockey, and even more swimming
0:02:03 > 0:02:05as the Olympics continue.
0:02:05 > 0:02:14Brazil!
0:02:14 > 0:02:14Thank
0:02:14 > 0:02:14Thank you,
0:02:14 > 0:02:16Thank you, Ricky.
0:02:16 > 0:02:18And we've been asking what you're looking forward to.
0:02:18 > 0:02:20Jess in London says she's looking forward to the swimming
0:02:20 > 0:02:21and athletics!
0:02:21 > 0:02:24And Carys says she'll be watching the gymnastics so she can use it
0:02:24 > 0:02:26to learn some skill herself.
0:02:26 > 0:02:28Thanks for those, get yourself online and let us know what event
0:02:28 > 0:02:31you can't wait to see at Rio and who you'll be
0:02:31 > 0:02:33cheering on from Team GB.
0:02:33 > 0:02:36From record-breaking athletes to the world's longest aircraft now,
0:02:36 > 0:02:38coming out of its hangar for the first time, ready
0:02:38 > 0:02:41for its first flight.
0:02:41 > 0:02:44Airlander is part plane, part airship, part helicopter
0:02:44 > 0:02:47and cost ?25 million to make.
0:02:47 > 0:02:49More tests are needed before it takes to the skies.
0:02:49 > 0:02:55The date of its first flight hasn't been announced yet.
0:02:55 > 0:02:57But that's all from me for now, Newsround's back
