>> all of them. every one. how can you love something if you don't know how much you have? >> reporter: the satellites circle over the north and south poles as the earth spins underneath and send back pictures of every square inch of the planet every day, including pictures of the 150,000 or so coral reefs. it's a game changer. until now, scientists have had to visit individual reefs to monitor their health-- or lack of it. this group was heading to australia's great barrier reef. as research, it's expensive, it's time consuming, and it's incomplete. what's the difficulty in trying to diagnose just what the health of the reef is? is it just there's so much of them and so few of you? >> yeah. i think you hit the nail on the head. just the fact that there's so much reef out there even when responding to something like the bleaching event has only a certain number of scientists.

>> reporter: emma kennedy has been studying the two recent bleachings here when warming waters killed coral, leaving a white skeleton behind. >> we have never seen that back-to-back bleaching before, and the satellite products are really going to help us. we're going to be able to look at much bigger areas of reef from space. >> reporter: and that's where the reef mapping satellites come in. >> it's a really simple, elegant solution. >> reporter: lauren kickham runs the project launched by the late marine enthusiast and microsoft co-founder paul allen to combine space and marine science. >> and if you zoom in, you can see more details of this reef coming up. >> reporter: the satellite pictures are processed by software chris roelfsema is developing to automatically color code what is coral, what is sand, what is healthy, what's dying. an online atlas will provide a daily worldwide coral health report. >> if we know that a reef is

under stress, then we maybe say, let's not go fishing there, let's not go having tourism there. >> if we didn't have what we have now, it would take trillions of dollars and 100 years to map the world and we just don't have that time. >> reporter: it is a race against time. scientists are expecting another coral bleaching die off as soon as this year. mark phillips, cbs news on the great barrier reef. up next, she was attacked by a jaguar. we have her first tv interview.

stitches and says the zoo put its barrier too close. zoo officials maintain the rules weren't followed. >> when people do not respect the barriers, there is always a chance that there might be a problem. >> reporter: leanne is hoping to turn her too close encounter into an example. >> i never expected it. and i feel like we're all human. we make mistakes. and i learned my lesson. >> reporter: and she says her next close-up may be further away. was it worth it? >> no, not worth it. not worth it at all. >> still ahead, they needed a ambulance after their plane experienced turbulence. billions of bacteria,

this is the cbs overnight news. welcome to the overnight news. good to have you with us. search teams in africa have recovered those black box recorders from the ethiopian airlines plane that crashed on take off this weekend. all of the people on board died in the wreck. that's raising questions about the safety of the brand new boeing 737 max 8 jet liner. this is the second time a 737 max 8 has crashed in the past five months. and now countries around the world are grounding their fleets of that aircraft.

within seconds of flight 302 taking off it was clear something was very wrong. the pilot made an urgent distress call wanting to turn the plane around. but then just six minutes into the journey, all contact was lost. it crashed about 30 miles from the capital. >> the pilot mentioned that he had difficulty and he wanted to return. so he was given clearance. >> reporter: eyewitnesses say the plane was trailing smoke and made a sharp turn before nose diving to the ground. "it came directly from the sky downwards," one man said. "we heard a huge explosion." piles of mangled debris lay scattered at the crash site. strewn amongst them, shredded clothing, a passport cover, a

single shoe. with over 30 nationalities on board the plane, there was heartbreak felt on every corner of the globe. pilots and crew of ethiopian airlines wept at a vigil for their colleagues. the united nations was hit hard, losing at least 21 staff members in the crash, many of them young people who wanted to change the world like the u.k.'s joanna toole and irish national michael ryan or british citizen sarah auffret who was tackling marine plastic pollution and award-winning nigerian author pius adesanmi. from saving refugees to fighting global hunger, the flight manifest read like a who's who of the very best of humanity. there was one person who should have been on that flight but narrowly missed it. antonis mavropoulos arrived just as the gates were closing, and despite begging to get on he was told he would have to catch a

later plane. the latest crash of the 737 max 8 made by boeing is disturbingly similar to the wreck of a lion air jet in indonesia last year. there's about 60 of the planes in service here in the united states flying tens of thousands of people every day. so the question is, should you be concerned? >> late this afternoon the faa sent a notice to all the operators of the 737 max around the world. in it the agency said it will likely require design changes to the max, but those stem from an earlier deadly crash. this as the world is waiting for clues to emerge as to what happened on sunday. investigators will be looking for any signs the boeing 737 max 8 that crashed sunday malfunctioned similar to the lion air 737 max that crashed in indonesia last october, killing all 189 aboard. the pilots of both jets reported technical difficulties.

the two planes appeared to struggle to gain altitude before making a steep nosedive and crashing less than 15 minutes after take-off. investigators will also probe the actions of the flight crew, the copilot of ethiopian flight 302 had just 200 hours of flight time. a u.s. airline pilot typically needs a minimum of 1,500 hours. the black boxes will be crucial according to john goglia, a former member of the n.t.s.b. >> so it's going to tell us a lot about how this airplane was flown in the last minutes, and also it is going to tell us about how the airplane was flown in the previous flights. was this a problem in a previous flight that is just coming to light on this one. >> reporter: tens of thousands of people a day fly on the 72 boeing 737 max planes operated by u.s. airlines. southwest, american, and united are sticking with the aircraft and the f.a.a. has not moved to is ing to fleet, saying it doe move aggressively should data

from the black boxes indicate the potential for a systemic problem with the max's flight management systems. >> it's definitely too early to know that. there is nothing in the factual evidence so far that would support grounding the airplane, nothing. >> reporter: but several countries and airlines internationally decided to ground the max, and the american airlines flight attendants union told members they don't have to fly on the max if they feel unsafe, though the airline itself said they have full confidence in the aircraft. now, boeing's c.e.o. sent a message to employees today that said in part, "we are confident in the safety of the 737 max." california senator dianne feinstein is not confident in the safety of the 737 max. she sent a letter to the f.a.a. calling for the grounding of all max planes until this n plete. let's talk some politics now. the iowa caucuses are only 11 months away. joe biden is ahead of the 27 likely caucus goer prefer mr. biden but 25% say they like

bernie sanders. >> reporter: former vice president joe biden is likely to join the race for president according to the man who replaced him in the senate, delaware democrat chris coons. >> he's someone who i am confident is going to run. i'm optimistic he's going to run. >> we're in the final stages of that decision. >> reporter: even before he takes the plunge, biden is leading the 2020 democratic field in iowa. 27% of likely democratic caucus-goers would pick him first, following close behind, vermont senator and former 2016 presidential candidate bernie sanders. but it's the man in fourth place in the iowa poll that republicans are worried about, former texas congressman beto o'rourke is the subject of a conservative attack ad in iowa, even though he's not yet in the his, yanlose a charmed life lik >> reporter: o'rourke joined more than a dozen declared or

potential candidates in austin over the weekend at the south by southwest conference, but it was biden who loomed large over the field. democrats welcomed him to the fray, but are focused on their own bid. so if he gets in, does he draw support from the kind of democrats-- >> you need a pundit for that. >> i have a lot of respect for vice president biden. and first we want to make sure he's getting in. but i can only address my own merits. >> reporter: another of the hopefuls, kirsten gillibrand, faces a new distraction with reports that a campaign aide resigned last year in protest of how the senator's office handled claims of sexual harassment. >> this investigation was thorough and professional and the allegations were taken seriously from the very first day. >> reporter: remember, it's early and things change. back at this point in 2007, republican rudy giuliani and democrat hillary clinton were leading their packs, but neither got their party's nomination. you're watching the cbs overnight news. we'll be right back.

native american. you're native american. >> but when she finally took a home dna test about five years ago, she got a lot more truth than she expected. she's part jamaican for starters and her biological father is not the man that raised her but a traveling guitarist named barren duncan. >> a jamaican touring guitarists. >> yeah. >> so crazy. >> he also had at least four other children. her half siblings. >> so you grew up thinking you were the oldest of two and in fact you're the oldest of five. >> exactly. >> do they look like you? >> so much. >> really? >> meeting my brother steven for the first time, it was like looking at my twin. i literally started crying as soon as i saw him. >> i found my birth mom with 23 and me. >> just to get to hold her again. >> she is one of millions that have turned to home dna tests and one of many that had their sense of identity shaken by the

results. 23 and me and ancestry dna warn customers that they could receive shocking information but neither company offers genetic counseling as part of their standard package. >> people are smart and capable. they can make sense of it. >> she is vice president of business development at 23 and me. she believes customers can handle genetic information just as they do the results of other home examines. >> people take a pregnancy test at home and if it's positive, which is significant information they then take the next step of talking to a doctor and we think dna tests are in the same vain. >> ancestry dna says it takes the potential impact of complex discoveries very seriously and has a team available for people with more sensitive queries but they also raise questions about privacy. 23 and me says it won't share customer medical data with third parties unless given consent. and the company says it uses two

factor awe the factor authentication and encryption to protect results and has never been hacked. but he says one breach would be hard to fixed. >> if you have a credit card stolen, you kanscancel it. if your dna gets revealed to the world and the hacker, it's hard to get new dna. it just doesn't happen. >> still we took a test ourselves and i braced for a surprise. >> i'm an only child of unmarried parents who lived a wild and crazy hippie existence. >> that never came. >> 26.6% italian. as expected with a first name like tony. >> she is still working through the meaning of her own results. >> so you're now jamaican-american. >> i guess. am i allowed to say that? i don't know? can a dna test tell me what i am and what my identity is? i don't know. >> but she is sure of one thing.

>> u.s. soccer is in a very unique position to take an incredibly bold stance. >> we spoke this morning with team members alex morgan and megan from france where they are preparing to defend their world title. >> megan, what message do you hope this sends? >> i think we have learned a lot through this process. we have really come together as a group and been able to solidify our unity and our strength and have really started to understand the power of everyone being on the same page and collectively fighting for what we feel that we have earned. >> in the lawsuit, attorneys for the women point out that if both the men and the women's teams were to win 20 nontournament matches the men would earn on average $263,320. that's more than 13,000 per game. while the average women's team player would earn a maximum of $99,000 which equals a little less than $5,000 per game. the u.s. soccer federation said
