bill pazert at jpl is not optimistic. >> we've seen drought building slowly for the last decade and a half. one el nino, one wet winter, will not be a drought buster. >> not far from jpl, is the morris dam an important part of the los angeles county water system. there, engineers are hoping el nino brings heavy rains they can capture. techknow's crystal dilworth picks up our story from there. >> scientists have been researching the impact of el nino from space to the sea but we have an inside look at how infrastructure is being prepared for the storms. >> we have invested a lot of time and money in doing projects over the last 10 years to make sure that these dams and infrastructure that was built in the 20's and 30's really are employing now the latest and greatest technologies. >> sterling klippel is a civil engineer with the los angeles department of public works. >> when you look out here you see this kind of ring that goes around the reservoir, i'm expecting we'll see reservoir levels all the way to the top of that ring. >> tell me a little bit about capturing the storm water. ho

s jpl was founded at caltech in the '30s and leads the way for robotic space exploration. in this edition of techknow on the road we take you inside caltech to show you the future of the scientific discovery. i'm phil torres and joined by dr shini somara, and dr crystal dilworth. crystal, you got your ph.d. , that caltech is a hot bed of scientific discoveries, happening every day. and today we are lucky enough to meet the scientists. >> absolutely, there's wonderful work. and we are caltech nerds. we have a reputation. we are featured a certain way on sit comes, "the big bang theory" tv show. >> exactly. i'll show you some of my favourite people doing incredible science. the m.e.r.s. is mcarthur -- first person is mcarthur prize winner, taking an approach to energy, global conservation. >> climate change is not a far-off problem in the future. it's happening now, causing hardship now. climate change is real. we have to act now. >> the debate about whether climate change existed at all is falling to the background. i think people accept it's a reality. it's here. now it's

the team at jpl broke down the myths and realities about how close science truly is to putting a human on mars. >> robert manning was the chief engineer of the real mars pathfinder which allows matt damon's character to communicate back to earth. he consulted with hollywood designers on a prototype for the film. >> i think it's very accurate. >> if nasa does get a person on mars in the 2030s, it will be in part because of jpl'ers like manning and jennifer trosper. she's the mission manager for the mars 2020 rover and well aware of the accomplishments needed to make it on mars. >> our next mission is going to do 20 samples on mars instead of 4 or 5 that curiosity has done so we have to figure out how to make the rover faster and smarter and more operable on the surface to collect these samples. >> nasa has proven it has the right stuff for sending robots to mars but there's a big leap needed before they send humans. >> lift off! >> the voyage could take up to 270 days. the international space station is currently observing how space travelers deal with this sort of psychological depriva
