of mexico up to 15 hours after falling overboard from a carnival cruise ship late wednesday night but he s alive because of an incredible rescue mission by the u.s. coast guard. nick valencia joins us. how did this happen and how did they manage to find him? this is the story of the day and will probably have a story for the rest of his life. he was a passenger on the carnival cruise ship from new orleans to cozumel for a five-day cruise. wednesday night he and his sister were at the bar and at 11:00 p.m. he told his sister he was on his way to the restroom and never came back. she goes to bed and wakes up noon the next day and reports him missing and they contact the coast guard and at 2:30 a search and rescue operation is launched. the cruise ship stopped and back t tracked to find this individual floating in the water for 12 to 15 hours. he was eventually spotted by members of a different crew
some time. yes, of course. what we ve found from data come back from the rover and studied over the last few months is that we see rocks, these are rocks that have been formed through volcanic processes which also were effected by the action of liquid water and that is interesting and exciting because liquid water is one of the key ingredients you need for life to start. so if you ve got the chances life being on mars, you need to be somewhere that had liquid water for a period of time and we have got good evidence for that. now that is combined with the fact that we re seeing using instructions like sherlock was an instrument i m involved with chemical molecules made of the elements, carbon, hydrogen, oxygen and nitrogen and sometimes with sulfur and phosphorous and other things and
countries rise, the countries we never expect to do well is also making the story line so much more interesting. for sure. that s why they play the game and why we keep watching them. christine brennan, we could tweet at each other as the games go on later today. good to have you on. same here, thank you. to space. the rover puncovered new clues that could give insight to the possibility of life in the past on mars. what researchers just found in the rocks coming up.
those are really important because you need molecules for life to start. and the other thing that is really interesting about organic molecules is they could be fossil evidence, fossil chemical evidence of potential past life. now it is very important to say that the organic molecules we found so far we cannot conclude, say or even guess that those are evidence of past life. to be able to do those type of experiments we need to do details experiments in labs on earth which we hope to do in the 2030s, when these samples will be returned from mars. okay. but there is more evidence coming from perseverance. and we ve seen some interesting results, very tantalizing. and the samples, they ll be put on a tiny rocket and sent back to earth. how much of a difference will it make to have the samples and you could determine conclusively once you have that stuff in a lab back here on earth? yes. that is exactly what we hope to
if you re living in the darkness of bipolar i or bipolar ii depression, caplyta can help let in the lyte. discover caplyta. caplyta is a once-daily pill proven to deliver significant relief across bipolar depression. unlike some medicines that only treat bipolar i, caplyta treats both bipolar i and bipolar ii depression. and in clinical trials, movement disorders and weight gain were not common. call your doctor about sudden mood changes, behaviors, or suicidal thoughts. antidepressants may increase these risks in young adults. elderly dementia patients have increased risk of death or stroke. report fever, confusion, stiff or uncontrollable muscle movements which may be life threatening or permanent. these aren t all the serious side effects. in the darkness of bipolar i or ii depression,
