mars 2020 mission. and as they're doing that, back in the hab the weather report on mars is updated, and a huge dust storm is coming in. what's great about that is we can actually do that weather report right now. we have global circulation models of mars, of the temperature and pressure, distribution over the entire planet that based on the data we're getting from our orbiters, we can actually do that in near realtime. so even that's quite accurate. but what's not accurate, of course, is the dust storm is worse than anything you saw on lawrence of arabia. [laughter] but the pressure is so low, it's about a percent of our own pressure, atmospheric pressure here on earth. and even though the winds can go 125 miles an hour, can be really brisk, it's not enough to straighten an american flag sitting on its surface. [laughter] sorry. sorry that's, you know, you may not have realized that. so it's very benign in that sense. but what it can be is crippling from an atmospheric perspective. the dust gets lofted

everybody is trying to get to mars, and i think what stands out with mars one is the permanent settlement. and i think this is the time now. >> so i'm really interested guys, would you sign up for a one way mission to mars. >> i wouldn't. >> you wouldn't? >> no. >> what about you? >> you know. i would possibly but i don't think i would sign up for this one way mission to mars. i mean, if you look throughout history so many pioneers and explorers were, to be fair, a little bit crazy, and sometimes they succeeded but other times they didn't but it would always push progress forward just a little bit. >> it's true. >> you know, i think the merit of this project is the fact that the goal is to try to be able to achieve living on mars. and the result of having a goal like that which is extremely ambitious is the amount of technology that's going to be developed. you know, just crazy inventions and innovations that are going to come out of quite a kind of "pie in the sky" objective. >> it's true. >> you know i think we've talked sustaining life on other planets versus sustaining life here on ea

that location is mars. we are so lucky to have a planet like mars. what will happen with mars? earth, it went through an enormous climate change, we do not know how fast, we do not know exactly when, but it happened on mars. what will happen to mars in the future? we now understand that a little bit better. if the heat from the sun continues to increase, which it then the temperature on dry will increase, the co2 ice cap will sublimate, producing a greenhouse effect which will melt the huge water -- cap.a significant a significant amount of the ocean will return, and it will look like earth again. we better be there when it happens. >> that is quite the endor. -- ender. [applause] >> you set the bar very high. thank you for coming. maybe we just have jim greenback every time. thank you. [applause] >> i would love to do so. there are so many other things we can talk about. thank you. >> c-span's washington journal, live every day with news and issues that impact you. coming up monday morning, patrick cocker, technology editor for defense one will talk about the use of cyber tech

marcus picking up samples on mars -- definitely the kind of thing we will be doing with the mars 2020 mission. that, there doing that bac weather report on mars is updated and a huge dust storm is coming in. what is great about that is we can actually do that weather report. we have global circulation models of mars of the temperature and pressure distribution over the entire planet that based on the data we are getting from our orbiters, we can actually do that in near real-time. so, even that is quite accurate. but what is not accurate of course, is the dust storm is worse than anything you saw from "lawrence of arabia." it isessure is so low, about 1% of our own pressure on earth. and even though the winds can go 125 miles per hour, it can be really brisk, but it is not enough to straighten an american flag sitting on the surface. sorry. you may not have realized that. it is very be nine in that tense, but -- it is very benign in that sense, but it is very crippling from an atmospheric perspective. it can go very high. at noon, it may look like midnight and it can get very dark. on

the exo-mars spacecraft left earth's orbit. it is a collaboration between the european space agencies. >> scientists hope the mission can help clear up questions about life on mars. >> we know more about the planet mars now than ever before. there are seven active orbiters on or above the planet. these are from the u.s., european union and from india. recent discoveries included the presence of liquid water. some below the service of the planet. and shed life on how mars's atmosphere was deflighted by solar winds. the big question, whether there was life on the planet, is unanswered. that's why the european and russian space agencies are sending the exo-mars trace gas orbiter to the planet. it uses a range of sensitive instruments to explore the atmosphere, looking at methane and whether it's used. >> methane is a hot topic. trying to understand the origin of the methane, and where on the service of mars and when and how it's destroyed is important. water has been seen on the surface. i think we need to understand a little bett
