premise of that. october 14, 1947, yager bought 714 miles which is mock one in this aircraft. he breaks the sound barrier. >> so let me go back to my question to you. >> what are your questions and what are the unknown and what answers are you looking for? >> aviation is an interesting topic. a lot of way, we docked 100 years. many people said well, the story has ben told and mature technology and nowhere else you can go with that. what's fascinating to me is what are the next steps. how are you watching the first -- are they going to lead

aircraft that actually enabling for you to fly to new york and take you for half an hour. wu hao are we going to track those? are we seeing those technologies being formulated or are we aware of them? >> that's a big question for me. >> what about private millionai millionai millionai millionai millionai millionai millionai millionai millionai millionaire entrepreneurials. >> the robinson race point. >> these idea or for private funding. always part of that idea and push thag envelope technology. >> a few more minutes. >> john is next. >> hello? >> yes, john, go ahead.

>> i was at the aerospace museum a few weeks ago, both of them and i was very impressed with e everything that was there. i want to thank everyone for what they've done. my question is will they be expanding it at some point of the world war ii two section, that's there. all right, it is a proposition 8 yes. world war ii is a anyway juror story and aviation, theme just draw people to it. it was made by people who flew spider airplanes in world war ii. so the people know what they are saying. we are looking at through this transformation of the museum, we'll do a nye gallery. we'll combine the gallery and world war world war ii and we'll provide a

larger c larger contextual stories. >> the rule is, here is a guy that's 22 or 23 or 25. 2039 is the ending of world war two. do we want to do this story right. rick, you got the last call from this statement from wisconsin. >> hi, my name is rick. i have two comments to make. the first one, i appreciate your show, i think it is great and especially seeing all the artifacts that you have. my question is do you think there are many items missing from display and how many think,

you have money to improve yourself for the next few years? >> part of our presentational duties, we have that's what you willed a collection rational. >> and also, says why we need and what we need. one of the new objects of what where he would take. so it can rain from a athlete airplane like a boeing 17 from world war two to apart of an airport. b 51 mustang. it is a critical element. we did not have a car. we were looking for it. >> these are displays as well as you record that story of technology and the people who made this. >> as general point out of only a small percentage in tour. >> we have a certain percentage

here and quite a few of ours are here. >> jeremy, he's the curator here. >> thank you very much for your time. >> it is space explorations from moon to mars, wsas we continue r thunderstorm inside this museum. >> the icon for the landing of the moon in july, 1969, it had a companion spacecraft, the apollo command module. it is service module and the luna module and neal armstrong and michael colins to the moon. >> the command module very significantly and also brought him back safely.

>> this mod jell is an actual mod jell that never flees in pace. >> it was intended to be used an earth orbital test fly but the test is cancelled. fiorina fiorina's trans fort, it consists of two parts. the base which have the legs. and the rocket engine in it. then the oddly shaped top which is the crew modular or -- this is from earth and to luna orbit. >> armstrong and aldridge climbed into the luna module, separated from the command module where michael colins stay to orbit the moon. i began to sat down the surface.

>> going forward, drifting to the right a little bit. >> okay? >> okay, engine stop, we are copying it down. the eagle has landed. >> this was was a thrilling moment in history and almost everybody who was alive at that moment remembered where they were. whether they were watching it on television or their own home or if they were standing in a client's store watching television. people around the world stop to watch the landing on the moon and the first step human being on the moon.

>> that's one step forman. >> after the apollo 11 crew have climb out, done some exploration close to the luna module collected. taken from photographs and placed a u.s. flag on the moon. and, this became their vehicle for their trip home. they launched the small top portion and leaving the base on the moon and they -- exited the luna module and once they were cure inside and reunited with

michael colins. the module was detached an and -- because miles just wanted to be able to track what kind of impact it made on the moon. so from a space historians's point of view. these two crafts, the luna module are the icon of the space along with the suits warn by the astronauts on the moon. this symbolized of a historic moment in time. july 1969 when human being first set food on another body in our toe lamar system. >> and, in a speck, but, children, look at this.

spacecra spacecraft, they often say that does not look like -- we tend to think space crack are always extreme line and -- but, this has an interesting design and many way, it is preemptive. >> it does not need to be streamed line on the outside because it is not going to operate it in the atmosphere. it will only operate in the vacuum of space. it would not be subjected to strong webational field on the moon. it asks for a fairly phlegm si in some area. >> the legs are obviously strong and the mountain for the rocket engine is strong. >> it had two windows, neal arm strorng had command at the craft during his final decent t

to -- they're pretty much filled of the internal volume in the po i serious condition. it was designed for comfort. it was designed for the purpose of landing so they can spend a couple of hours on the surface of the moon and launching again across with their cargo to bring back home to demonstrate that they have been there and to have those materials for scientists to begin to analyze and better understand the moon. >> it is also amazing to think that the computer power required in that day to send these crafts to the moon and to program for the lawn. was done with fairly primitive

computer program and memory was a -- the competing power that we old in our hands with our smart phones, it is faster than it took to send people to the moon and back. we give you a step of - of -- dividing the solutions and getting people to the moon and get back safely >> we have seen the iconic artifacts from the heroic age of pace cheese in the 1950s. our next stop is sky land. we'll take a look at that. it is one of the original artifacts on display here since before this museum opened. >> it is so large that it was brought into the museum before the billing was closed out.

>> now, i am standing in front of a model in inside of the sky lab that's as tall as i am. the real kai lab absolutely dwarves the model and me. two stories tall. >> sky lab was the united states' first space station. he was put in orbit of 1973. three men at the time and one group was fair for one month and another group for two months and a third group for three months. the whole point of the mission was to get some experience and living and working and space. >> there was still some hardware

left over. also, we still have a couple of powerful rockets on hands. can we repurpose them and do something else? and so, the decision reached was to take the third stage of the gigantic -- that powers the spacecraft and turning it into a module of sort of a nurture space station that crews could live in while they're getting this experience and living and working in space. the actual element that is behind me is the full cylinder that's marked by this wide, wide band here. you can see from the cut there, it is tooth stories on the

inside. those are the two astronauts could actually live. in the mission to the moon and the orbit, they have been in spacecraft that were cockpit. >> they had no more room for them in the sports car. there was a galli room where they can prepare food and eat together. they still were eating at a plastic bag and fortin can. but it was least more humbling and socialable. >> they had sleeping corners. peach member has a private area to retire from solitary time and from sweets, without being come

fi come fined in the seat. >> it had an actual bathroom and toilet. in our mission, the little known 30 secret is the astronauts were using plastic bag to collect their waste. finally, they had a toilet and they did not have to deal with the mess of taking care of their bodily function. it had a zinc where they could wash up and save and it even had a showers which was essentially a ton of like sheet. an astronaut pulled up around him and could use water from a sprayer inside that container. all the water had to be wiped off the body and wiped off the

ensure part. >> they would take sponge path. having some experience set up and they had a huge attic above the living area where their extra f extra supplies were stored and a lot of elements were there. >> they can run tracks around the perimeter of it and tumbling around the perimeter. running and tumbling across the top and the lockers. that was for fun but they actually use that space for serious reasons, too. they were testing out a jet backpack and that maybe used. they were able to operate that in that attic space. below the living deck floor, there was the remainder of one o f the propellant tank and that

became their big trash can. >> they can put the trash through the hatch and it goes down to the lower level. >> the largest part of the sky labs space station but above it, there was an air lot module that enabled him to go outside and to surface this seratory. it was a wonderful scientific facility attached to the orbital workshop. >> ywe got our first really detailed use of activity on the front. we understood for the first time how dynamic our sun is and how

it is spearing out big explosions of manner and it had holes in it and storm fallen on it. it was an amazing scene to get this new and information through the telescope on style tab. >> and here is the top. one can see the docking port for for -- certainliy bringing the craft. it is 22 feet in diameter. again, when you think of the engine annuity, a turning and a stage of a rocket which is basically a big fuel tank into a home that people can live in and you can provide them with blu p plumbing and comfort.

>> this was a turning point in our space program. >> sky lab was the next early 1960s on, planners in the united states had foreseen an eventual space station. in fact the original plans were to build a space station in earth's orbit first and then go to the moon. but president kennedy reversed that and decided to send the united states to the moon first, as part of the cold war competition with the soviet union. so in the back of everybody's mind there was still a space station. sky lab was the first step toward what now has become the international space station. a huge new facility in earth's orbit. now this behemoth behind me is actually the backup sky lab

space station. it is flight ready. nasa built two of them in case they wanted to do two sky lab missions or in case there was some hardware problem with the first sky lab orbital workshop. we did make a modification to it. ordinarily we don't modify flight ready hardware. but in this case we cut a passage way, two doors into it, and laid down a sort of hallway right through the middle of the living quarter. so people who visit the museum can walk inside sky lab, they can see the living quarters, they can look into the bathroom. they see a mannequin at the table with some food out on the table. the shower is set up there. the exercise bicycle is in plain view. they can see the trash air lock right there. and if they look up, they can just be wowed by the amount of

free space there is. i mentioned that sky lab was occupied in 1973 and '74. the last crew to leave sky lab buttoned it up and put it into sleep mode with a view toward a future crew possibly coming back. and then nasa got very busy developing the shuttle. so what happened to sky lab? well gradually over time its orbit began to deteriorate somewhat. it started dropping lower and lower. and there was an early plan to use the space shuttle to go up and rendezvous with it and boost it back up so it could still be available for use. but the shuttle wasn't yet ready to fly. so what happened is after the orbit diminished, nasa has to bring it back then in a

controlled reentry. so in 1979 sky lab was brought back down, it streaked into earth's atmosphere like a meteor, it broke up over the indian ocean and a few pieces fell in parts of australia and were recovered. but fortunately no one was hit, no one was injured, no property was damaged. now i paused here at sky lab because this was still news in 1976 when this museum opened. people streamed in here literally by the millions that first year. they were thrilled not only to see the old aircraft but to see the new spacecraft, to see what had been happening in space that they had seen on the news and heard about. and sky lab was one of these featured attractions. well now we are in the exploring the planets gallery where we

really focus on recent events in planetary exploration. and this is one of my favorite parts of the museum because this is where we display the three rovers that have been doing major research on the planet mars over the last 20 years. first rover to land and operate successfully on mars was one identical to this one. it was part of the pathfinder mission of 1996. and a little rover named sojourner was put down on the surface of mars and it operated long beyond its expected lifetime, exploring around in the vicinity, as you can see it has six wheels and they're a kind of wheel called rocker wheels that will enable it to go over rocks without tipping over. it is about the size of a microwave oven if you imagined a

microwave oven having wheels. it has solar panels on top to keep it powered. and it was really a little geologist that was put down on the surface of mars to do some of the kinds of investigations that a human geologist would do. it is equipped with a device to touch up against a rock and determine what chemical elements are in that rock. it had a camera for guidance. it could also hiccup information about the ambient environment of mars. so you can think of marie curie as this one and sojourner as the first geologist to set foot on mars and go roaming around so they could explore a broader area. this is actually the backup for the pathfinder mission. this one could have gone to mars itself. ten years later after the pathfinder mission, we had

another mission that landed a somewhat larger rover on mars. and this is a model of spirit and opportunity. this is an engineering model, though, and isn't really ready to go to mars. but you can see the growth since the first rover. this one is more like the size of a golf cart, perhaps, again with the special wheels so that it can operate well on the uneven terrain. and it's equipped not only with the solar panels to keep it powered up, but with larger and more sophisticated instruments. it has a robotic arm that extends out. it has almost a head here at the front, at the top of this long neck. and that's where the cameras are for its movement around. it enables scientists here on

earth to see where it's going and see what it's seeing. it has various other scientific devices on it. and again, a kind of mars weather station to determine what is the ambient environment like. what is the wind like. what are the temperatures at different times during the martian day. what is it like when a dust storm blows up and passes through. so, again, this is a more capable geologist now that's on the surface of mars. but one that is mimicking some of the capabilities that a human being has. spirit and opportunity were launched to mars in the year 2004, and opportunity is still operating, still roaming around on mars, sending back good data. again, long outliving its life. so now we'll have a look at the third rover that's on the

surface of mars. and this one landed in 2012 and is still working today. this is a model of curiosity. curiosity has just grabbed public attention because first of all, it's so big. it's like having a car on mars. and this is the one that had the very dramatic landing sequence where it was dropped from a crane that was descending from the orbital spacecraft. and it was called seven minutes of terror to get it down to the surface of mars without it being damaged. but it was a very successful landing. and curiosity has been roaming for kilometers on the surface of mars. it's studying planes. it's on the rim of a crater. it's going down into the crater

to have a look at what the surface geology is like there. and the main mission of curiosity is to follow the water. scientists have a lot of evidence that at some point in the past mars had a lot of water. and the evidence is in sedimentation on and in portions of land that look as if they have been washed over by water which then evaporated. and so the thrust of the curiosity rover is to investigate sights that seem to have had an abundance water at some time in the past. once again, this is a surrogate for a human geologist, much larger in scale than the pathfinder and the spirit and opportunity rovers. much sturdier structure. a chassis that really is the size of a compact car.

again, a suite of cameras and weather station instruments on board. and this one is also a chemistry lab. there are several devices on here that can do analysis of the chemicals in the soil and in the rocks. it's really being a very exciting mission. and it has no end in sight. i think the public has become very fond of these rovers because they sense that they are surrogates for us and maybe pathfinders for us. they're doing the initial reconnaissance of the surface of mars so that if in the future humans actually go there, they'll know a lot more about the terrain and also know a lot more about sites that might still harbor moisture, if not actual water.
