in planetary science, it has certainly been the top priority to go to mars, return a sample from mars. followed by exploring europa. helio physics, understanding the processes of the sun, space weather. in astrophysics, completing jwst, and w first would be the current top priorities. we are about to engage in the astrophysics community in our process of looking at the proposed missions of identifying the next set of priorities. i think we'll begin by thinking about the key driving questions. the search for life will certainly be one, others will include understanding the processes of galaxy formation, star formation, and universal destruction. ,nd in earth science and space as ranking member markie mentioned earlier, using the vantage point of space to watch the changing environment is another key part of nasa's mission. the remarks started with the greeks and the planets, and i think a priority should be finding the true birth twin -- true earth twin. it is a huge problem, but something that america is leading the way. the star shade is not being developed in any other country. look

progress continues on the mars 2020 rover which will carry a small helicopter to mars but a first for humanity. nasa is planning for mars sample return mission. i top priority identified by the scientific community. during 2019, nasa will continue development of the cutting edge - - mission to fly by jupiter's ocean moon. one of the most promising targets for finding life in our solar system. in many ways, nasa astrophysics and - - programs are working more closely together than ever. the search for life as will be discussed by the other witnesses here later. nasa is committed to answering the big questions and it requires commitment to new and challenging missions. in 2021, nasa observatories will be joined by the james webb space telescope. it will be capable of examining the first stars and galaxies to form and viewing the atmospheres of nearby planets, outside the solar system. the web telescope and instruments are fully integrated and performed superbly during testing, comprised of a tennis court sized sunshield and undergoing testing. in march 2018, nasa recognized that it would

mars. using radar profiles collected from a satellite between may 2012 and december 2015, scientists have found evidence of a 12 mile wide reservoir of briny water beneath the south polar layer deposits. and just one month prior to the announcement of this discovery, nasa reported that the curiosity rover had found new evidence, preserved in rocks on mars, suggesting the planet could have supported ancient life. we are making progress as we search for life's origin, evolution, distribution, and future in the universe. as we look to draft a new nasa authorization act, hopefully this year, it is imperative we not only make progress answering but that we also equip nasa with the capabilities it needs to support science missions and priorities that will lead to discoveries across our solar system. this is a momentous time to be involved in space exploration, and i look forward to the testimony of our esteemed witnesses. now recognized senator markey, the ranking member, or his opening remarks.

but the falcon heavy now has the capability of taking payloads to mars rather significant payloads and. you know one of the exciting things that happened is that nasa as a space agency. originally kind of was reluctant to get involved with the private sector bug. but. that was i think one of the successes of the obama administration's space policy was that they basically directed nasa to work with the private sector for lower thor bit launches and for taking crew up to the international space station and so this idea of a public private partnership. i really look at as being the key to success for the future. we're not going to have another apollo program whether for the moon or mars i mean apollo was a very special time we had a cold war going on between the u.s. and the soviet union space had been identified as one of the areas in which you could demonstrate the superiority of your culture and you know the the russians were launching things first and then the americans and finally we got to the moon first. but at a tremendous cost i mean at the height of the apollo program over four

that is why i'm optimistic it did evil on mars. i'm not optimistic that it got very complex, so we talk about finding the fossil microbe single cell organisms, blue-green algae type, so hard to find. that is why i do think it will take humans on the planet breaking open a lot of rocks to find this evidence. .. >> 1 billion years they would be advanced if you think how much advancement we have had. are we confident we are searching in the right way for civilization that could be so far advanced had we even know how they are communicating? it is a broad philosophical question but if we are putting research in those intriguing question of life in our planet medicating we are headed down the right half looking for one t-1 once we start to realize how common my sellers mom -- solar system and gives a better data for the service conditions on t-1 on how is complex life and where do we go to find that? i think we need more data the way we approach the problem is correct with the exoplanet. >> thank you. >> we will do a few more questions.

so in planetary science, the top priority to go to mars, return a sample from mars and follow-up by exploring europa. understanding the processes of the sun and space weather. in astrophysics, completing jw st would be the current top priority. we are about to engage in the astrophysics community in our process of looking at the proposed missions and identifying the next set of priorities. we will begin by thinking about what are the key driving questions? the search for life will be one. others will include understanding the processes of galaxy formation, star formation and emergence of structure. in earth science, space, markey mentioned understanding the earth, watching the changing environment is another key part of nasa's mission. >> chairman cruz's remarks started with the greeks and the planet and i think a priority should be finding a true earth when orbiting a nearby sun like star and that is a hard problem. one part in 10 billion. it is something america is leading the way. the star shade is not being developed by any other country. >> we want to search for faraway planets but also

we're not going to have another apollo program whether for the moon or mars i mean apollo was a very special time we had a cold war going on between the u.s. and the soviet union space had been identified as one of the areas in which you could demonstrate the superiority of your culture and you know the the russians were launching things first and then the americans and finally we got to the moon first. but at a tremendous cost i mean at the height of the apollo program over four hundred thousand people were working on apollo it was for about two years nasa was getting almost four percent of the u.s. government's budget that's not going to happen again so nasa if they're going to be successful in space exploration has to learn to do it not apollo style but affordably and i think therefore there's a lot to be learned from the public sector and by working with the public sector and using these developments particularly the rockets and the spacecraft developed at a much lower cost than nasa has previously been paying for launches that might make it possible on a much more limited budget

and we are going to go to mars. first person to step foot on mars will get there on his own rocket. david: will they come back on boeing rockets? [laughter] david: all right. dennis: in boeing's version, that is always a two-way trip. [laughter] david: it takes six months to get to mars, right? dennis: on average. david: there was a plan called the concorde. why do we not have a supersonic transport any longer? dennis: did is the economic hurdle that goes with it. that plane was never economically five ball on its own. to fly supersonic, you burn two times to three times as much fuel. i envision a day where we not only see commercial airplanes like today's airplanes, we will see high-speed airplanes that can connect any two cities in the world and about two hours, and we will see that span up to space tourism, and eventually an economically viable space ecosystem in low earth orbit. you will see an intersection between commercial air travel and high-speed travel, and space travel. that will evolve over the next coup

there are these three guys in mar-a-lago.adership for the department of veteran's affairs. they don't have any official role in government, they've been doing this without any accountability or transparency. very few people outside the va had any idea this was going on. >> who gave them the authority to do this? >> the president. you think back to the transition, there was a period where trump was asking a bunch of his rich friends to get involved. there was a time where carl icon was going to do deregulation, and rudy giuliani was going to do cyber security. perlmutter said, i'll help you fix the va, so then perlmutter got sherman and moscowitz involved. unlike these other guys who sort of tide away, this one has not only continued but deepened to the point that they managed to stack the leadership of the agency with people who were loyal to them because anyone who didn't get along with them got pushed out or pushed over. >> what expertise do any of these men have, in veteran's issues or running of the va. >> that is the exa

thirdly, that these ufos are most likely from mars. he is not a venus fan, he is on the marsh train. what is interesting about kehoe is that he does see a conspiracy he does see a conspiracy by the military to cover up the reality that is being visited by these flying saucers. but, he does not blame them for doing so. for kehoe, what he calls the silence group is acting out of a desire to prevent public dysuria. while he disagrees with that decision, he sees his -- it as a matter of disagreement. that is an idea that is going to change significantly over the 60s, and especially coming out of the 70s into the 80s. it is really easy at the time to see the impact of writers like kehoe to see a conspiracy silence, but not necessarily -- in 1952, that same year that true magazine is debunking scully, life magazine leads with a big front cover splash of marilyn monroe and the headline there is a case for interplanetary sources -- saucers. they think something probably is going on with ufos. less concerned with that ability, but no less influ

he's not a venus fan, he's back on the mars train. and what's interesting about kehoe is that he does see a conspiracy. he does see a conspiracy by the military to cover up the reality that earth is being visited by these flying saucers, but he doesn't blame them for doing so. for kehoe, what he calls the silence group, is acting out of a desire to protect national security and a desire to prevent public hysteria. and while he disagrees with that decision, he sees it as a matter of reasonable disagreement. he doesn't see nefarious motives at work. and that is an idea that is going to change significantly over the '60s and especially coming out of the '70s into the '80s. but it's really easy at the time to see the impact of writers like kehoe who see a conspiracy of silence but not necessarily a nefarious conspiracy of silence. right? 1952, that same magazine "true" magazine is debunking scully, "life" magazine leads with a big front cover splash of marilyn monroe and the headline, "there is a case for interplanetary sources." and "lif

that is in essence our mission to mars. we not want only everything to be reusable, we want everything replicable for a mars mission and take advantage of our commercial partners and international partners. if we want to create this sustainable, lunar architecture, again, we are not doing apollo again, -- and i want to be clear, apollo was amazing, incredibly important. we proved the united states of america had a superior political and economic system and that we were superior technologically. we want to establish a lunar architecture sustainable for the long run that brings along our international partners and commercial partners to do more than we have ever done before. all of this is about one thing, that is improving the human condition on earth. that is what nasa's vision is. >> a quick word about the study of the sun that will take place. jim: a wonderful question. the parker solar probe will soon launch. this will enable us to know more about the sun. we talk about a level event, a coronal mass ejection out of the s

that's a full scale model of inside mars lander. it was a picture-perfect liftoff in may. inside lander is carrying a sizeometer. the goal is to study the planet. >> we're go doing problem did depth. figure out how big the core is. using that information we'll test our models of how mars formed be how the earth formed. >> there's been other missions, they will take the vital side of mars, far below the surface. >> we're measuring the planet to understand the entire blabet. >> an according -- planet. he's the first elected official to serve as nasa add mr. >> -- administrator. >> if you think about jpl. go back to the first satellite that america launched was produced by jpl. >> whether asked about his thoughts on a space foust. >> the potential advisories declared that it's a threat to the united states. the house of representatives had that intelligence. they voted on the space core. he wants a separate space force. >> while that may or may not be a thing of the future. the focus so is on september 26. a new ride share service is putting the safety of women first. the fou

so the va secretary wasn't even going to the meeting at mar-a-lago about the va. it seemed odd to me. except it won't. we now know about the true rulers of the va. there is ike perlmutter. bruce moskowitz and wealthy attorney marc sherman. none of them were veterans, none of them elected. and none of them confirmed. yet because they are friends with trump, and pay dues to his private club, they have been allowed to run the department. take us through the details of this absolutely insane example i am joined by isaac. this is one of the nuttiest stories of the trump era i have read. how involved really are these three gentlemen in overseeing the va? >> they are involved with everything. they speak with va officials every day on the phone. they have a hand in all manner of policy and personnel decisions that have been coming out of the va for the past year and a half. >> every day? >> as often as every day or multiple times a day. >> this is like how everything about the policy for the largest health care system in the united states. >> yeah. this is like how much h

officials traveled to mar-a-lago at taxpayer expense to hear their view.through any kind of confirmation exerting some policy role. taking place at the private business the president owns. taxpayer. >> a lot of this speaks to chief concerns that you have in the administration. close long standing ties with many of these billionaires. the question is does that get to overlap. you know, or can be spoken to by the american people. that seems fairly undemocratic, but this is part of what democrats are trying to do in painting this administration as people who are grifters and only about their fellow elite. >> it is interesting too, nick, the question is how many people are going to notice a story like this. i'm thinking about ten years ago a previous administration, there was a va scandal and it got constant week's long attention in this country. we live in an age where the president can tweet five provocative tweets by the time i finish my sentence. and we are now on something else. everybody moves on to something else. >> possibly, but one group that will pa

just how soon we'll be buying tickets to mars is up for debate. >> mars takes about 6 months to get to there's a long journey. there are technical challenges, but i think people will be flying to mars in the 2030s. >> i hope so. i think it will start with trips around the moon. >> reporter: but whether it's to the moon or mars, odds are good that the kids here today will have the opportunity to vacation in space. they may even help build the technology to get there. >> i would love for him to. i know he will. >> and the museum is open to the public friday through sunday. admission is free. obably isn't what comes >>> and coming up, when you think of tourist areas in the bay area, concord probably doesn't come to mind. and that's exactly what the city is aiming to change. >> also, a big turnout of volunteers today to help find a missing 14-year-old girl. her parents say she disappeared without a trace. >> and the all-important back to work forecasts include a bit of smoke and a bit of fog. but no mirrors. we'll have it after the break. ramon... to search for a missing teenage girl. 14-y

and the same thing for mars. and my main impetus is i'm a humanist, and i'm afraid we're going to blow ourselves up on this planet, and it would be nice to have some people on mars and on the moon in case the earth ended for human kind. i'm really pro-human, and this is sort of like an insurance policy. so i would like to see some colonies on mars and on the moon. and now the question is, well, how do we conduct business? hopefully with the least government possible and with the most private property and free enterprise possible. that's one aspect. the other aspect is, well, how do we get there? the spaceships? so far in, what was it, 1969 when the first man arrived on the moon? it was government. it was a government employee. my hope is that we do this private enterprise. why again? well, it's more efficient. and it's also more ethical because the government demands taxes from us whereas if somebody has a private rocket ship, he does it on his own account with his own money. so those would be my two ways of deal
