msl just got ned curiosity it does got to get in the habit of not calling it msl which is an acronym f the mars science lab, but curiosity which a student one in a contest. of course telescopes are great things. before telescopes' mars mythology was the roman god of war and temples were built and in athens you can look in honor of mars but then telescopes' came along and of cours we started figuring out the planets orbited around around the sun and galileo of course made these wonderful telescopes, and once people started looking at mars they discovered things like the poll of mars and was discovered feures on mars because of the quality of the telescope's imaginations went a little bit wild and he believed he called these canelli. with this idea of canali and possible water there might be other lifen mars and what it might look like folks had to use their iginations. a good as jn test observed this and tried to map this out, and of course there was this 1938 radio drama where the invasion of the marcion's was happening and it scared the dickens out of all sorts of people, like a ser

msl just got named curiosity and i got to get in the habit of not calling it msl, which is kind of a nasa acronym but curiosity which a student won in a contest. telescopes are a great things. before telescopes mars and mythology was, you know, the roman goddard of war and temples were built in athens. you can go look in honor of mars. but then telescopes came along and, of course, we started figuring out the planets orbited around the sun and galileo, of course, made these wonderful telescopes. and once people started looking at mars, they discovered things like the pulse of mars, casani and there's lots of features on mars and because of the quality of the telescopes, imaginations went a little bit wild and he believed -- he called these canelli, these features and made up maps of them. .. the marcion's was happening, it scared the dickens out of all sorts of people. hollywood picked up on this, since 1964, a few of the movies that involved mars, classics like santa claus conquers the martia martians, little green men who were not friendly to us. now the idea is we are not looking

msl will reach mars.he next three steps in mars exploration will include -- include atmospheric experiments. and something we have been thinking about since 1976 but up until the deadly three letters of the most mentioned. it is the road to human exploration, mars sample return. a lot has been said about that. this is a concept we have been working on at jpl and across nasa for almost the last seven years. it is to use the technology to land as three separate systems, the building blocks of returning materials from mars safely to earth for analysis here. where billions of dollars of labs will be ready to collect the materials discovered and brought back. this is a mission that really couples geology with astral biology. how we search for life on the planet and the records and rocks and soils and the frozen stuff. here you see one concept for the mars sample return mission lander. it includes as part of that land not only a little fish rover. these are the solar panels. but it would also include a mars as

msl is going to truss to its breaking point. okay. sample return is where the mars program realizes it needs to go to and is a good mission to connect human and robotic exploration. the first sample return could be a very simple mission. phyllis and third. but it in a rocket. send it back to earth. altman the we need to use the same approaches that we would for humans. so the simple returns will be our first round trips to mars. it is an important concept. robotic missions to mars today have been one-way trips. i know most people talk about humans on one-way trips humans are going to do round trips. sample return would be our first round trip. we use that technology for humans to do sample returns. there has been a study looking at how we can use the same rockets and vehicles to drive sambo returns. so to look at it during a large map of mars landing vehicles to do multiple sample returns deterred. and i'll test quickly show you some of the islands of that. but duke and pack a lot of mass. you can to a sample return and a single motio

there's been a lot of talk about the problems with the msl and how that's going.ave they considered, you know, instead of spending all this money developing a new probe, to answer questions at one site, spending an equivalent amount of money and sending out a bunch of rovers that we knowow to build to a bunch of different sites and answer a lot of questions? >> i know that a lot of scientists and many of those working and engineers who are working on the mars exploration rover tm feel exactly that. why didn't we just build more of them and go to different places? part of the answer is bound up in the philosophy of developing more and more technology that can take us upo the point of leading to mars sample return and building more vehicles and always building -- improving on what we did in the past by taking bigger steps in the future. but there's a very good argument for why not build instead of two mars rovers, the spirit and opportunity, why not build half a dozen of them and let themo to different spots on mars and gain a lot of experiences and scientific under
