for the answers to the following questions what is the x prize 00:00:00
why are aviation and space contests important 00:00:06
what is the purpose of simulated mars habitats on earth 00:00:10
doing all right ready to go for this thing 00:00:30
today i tested out at three g's in the centrifuge it was a very intense 00:00:34
experience as a centrifuge spun around to simulate the heaviness of a rocket 00:00:37
launch it was really difficult to move my arms 00:00:41
and legs for such a long time 00:00:44
i've been here at space camp for almost a week now and i feel really prepared 00:00:49
for my last mission wish me luck 00:00:52
what exercises really changed my life i think i can feel myself getting 00:01:00
healthier every time i run maybe you should volunteer for an 00:01:05
experimental research project do they give prizes or money if they do 00:01:08
don't tell tony because we'll find ourselves under 00:01:12
strict observation in the treehouse for the next six months 00:01:15
i've spent a few days here before it's not that bad well speaking of prizes 00:01:18
tony sent us an email and said to be sure to check out the x prize 00:01:22
there must be money involved 10 million dollars 00:01:26
what sign me up what do you have to do to win the 10 million dollars 00:01:30
i'm not sure but tony said to contact mr eric linberg 00:01:34
i wonder if he's related to charles linberg as a matter of fact 00:01:38
he's his grandson here he is now hi you must be the treehouse detectives 00:01:41
i got tony's email how can i help you guys 00:01:46
hi mr linberg we want to know more about the x prize 00:01:49
what kind of contest is it it's a 10 million dollar prize to be awarded to 00:01:53
the first privately funded suborbital space launch 00:01:57
that doesn't sound too hard well to win the prize 00:02:00
you have to be able to carry three people to an altitude of 100 kilometers 00:02:04
or 62 miles return safely that's important and do 00:02:08
it again within two weeks okay maybe that's a little harder why 00:02:12
was the x prize created the mission of the x prize is to create 00:02:16
a future in which the public can personally participate in space travel 00:02:20
and its benefits i'm there just tell me where and when i 00:02:25
can go how soon can tourists go into space 00:02:28
oh hold on a minute no one's won the prize yet but when 00:02:32
someone does win the prize it'll probably take a year or two before the 00:02:35
paying public can go and fly into space who started the x prize 00:02:39
peter diamandis was reading my grandfather's book the spirit of saint 00:02:43
louis when a light bulb went on in his mind and 00:02:47
he thought that's it we need a prize for space travel that's 00:02:50
how i'm gonna get to space in 1996 we launched the x prize 00:02:54
under the arch in saint louis danger grandfather charles limberth 00:02:59
and the ortig prize in 1927 for being the first person to fly solo across 00:03:03
atlantic ocean very good you know your history people 00:03:07
often forget that aviation was developed by 00:03:11
contests and prizes like the ortig prize and the bendix prize 00:03:13
and we hope to do the same thing for space travel with the x prize 00:03:17
what will happen to nasa if we have commercial space flight 00:03:21
well private industry can often operate more efficiently than government 00:03:25
and private enterprise will allow nasa to concentrate on their core mission of 00:03:29
science and exploration without having to operate a space 00:03:33
transportation system i guess nasa doesn't operate the 00:03:36
airlines today even though in the early years when it 00:03:40
was naca it was important to the development of commercial aviation 00:03:42
that's right and the more people who have the opportunity to fly into space 00:03:46
and look at our planet and experience what those astronauts 00:03:50
are telling us as a life-changing experience the more 00:03:54
they'll work harder to try to save our planet and the quality of life 00:03:57
that we know for future generations now this is truly 00:04:01
exciting to think that i might get to go to space 00:04:05
as a tourist thanks mr limburg you're very welcome i'll see you in 00:04:08
space fantastic next stop mars 00:04:12
one step at a time space cowboy seriously didn't tony tell you 00:04:17
corinne is already on her way to the mars society research habitat 00:04:21
oh right i forgot i can't wait to read a report 00:04:24
it's like a postcard from the red planet and isn't bianca simulated spacewalk 00:04:28
happening later today yes it is she said we should contact 00:04:33
space camps mission control this afternoon 00:04:37
we've got trios detectives on mars performing spacewalks developing rovers 00:04:39
and landers we're practically on mission control 00:04:43
we are go for liftoff 00:04:46
dr muscatello said he would meet me at the mars analog research station 00:04:55
but where is it my gps says it should be right about 00:04:59
here 00:05:03
wow dr muscatello this looks just like mars 00:05:16
it is so cool actually on mars it's quite cold 00:05:19
around minus 60 degrees celsius if we're really on mars 00:05:23
you'd be frozen why don't you come inside 00:05:27
if it's so cold on mars why do you have the habitat in the middle of a hot 00:05:34
desert we built it here because this environment not only looks as alien as 00:05:39
mars but it also exhibits landforms made by 00:05:42
infrequent rain and wind that are very similar to the martian 00:05:45
landscape what is the purpose of the habitats 00:05:48
the idea behind the habitats is to build simulated mars bases here on earth 00:05:51
in places that resemble mars as much as possible then scientists who volunteer 00:05:55
their time live and work there and study the biology 00:05:59
and geology of these mars-like environments 00:06:03
where are the other mars habitats oh we have one in devon island which is in the 00:06:06
canadian arctic that's a polar desert just like mars a 00:06:10
third habitat is being installed in iceland which resembles volcanic areas 00:06:14
of mars and a fourth one is being designed for 00:06:18
australia which has lots of very dry red desert terrain 00:06:20
so what kinds of experiments do scientists do in the habitats 00:06:23
scientists live and work here just as they would on mars one ongoing research 00:06:27
experiment being conducted is to look for microscopic life forms 00:06:31
called extremophiles that can survive in very extreme 00:06:35
environments why do they look for extremophiles mars might have similar 00:06:37
organisms so we need to know where to look and what 00:06:42
characteristics they might have scientists are also looking at rocks in 00:06:45
the desert that have a coating called desert varnish 00:06:48
which looks like a stain why is that important 00:06:51
the varnish rocks have a biological component that eats the rock 00:06:54
on mars the spirit rovers examine rocks with varnish as well 00:06:58
so there might be a form of life on mars do you have your own mars rover 00:07:02
no but we do have transportation we use atvs just like you did today 00:07:06
scientists use atvs why would a scientist need an atv 00:07:11
to evaluate exploration techniques they might use an atv to extend an 00:07:16
astronaut's range cliff reconnaissance vehicles can 00:07:20
descend steep embankments their research might be useful to help us 00:07:22
learn how to overcome the limitations of living on mars 00:07:26
i would love to live on mars and ride atvs well let's see what it would be 00:07:29
like but first we have to put on our spacesuits 00:07:33
spacesuits i don't have a spacesuit 00:07:35
wow this is great do you think that we'll really go to mars 00:07:43
most definitely we already have the technology to travel to mars 00:07:46
we would just have to be very clever and use the resources that are already on 00:07:50
the red planet what kind of resources does mars have 00:07:54
the atmosphere of mars has a lot of carbon dioxide 00:07:57
which you would combine with hydrogen brought from the earth with the right 00:08:00
catalyst you make methane which is your fuel for the return trip 00:08:03
home but what would happen if you got there 00:08:06
and the process didn't work with a plan developed by robert zubrin and david 00:08:09
baker called mars direct you would send the earth return vehicle 00:08:13
to mars without astronauts who would land and start making fuel 00:08:16
once you knew the fuel tanks were full the astronauts would leave earth 00:08:20
speaking of leaving earth can we go exploring you bet 00:08:23
but don't forget your helmet and backpack yes that's very important 00:08:27
are you ready to see mars you bet 00:08:31
bianca can you give me the order of switches to deactivate the antenna 00:08:47
roger turn off b2 b3 b4 b5 and finally b1 00:08:51
roger our eva mission is on target going to get the broken antenna 00:08:58
this is excellent work keep up your concentration 00:09:04
space camp this is mission control the satellite is worse than it was before 00:09:07
wait a minute that sounds like jacob you got me 00:09:12
katherine rj and i are monitoring your progress from the treehouse 00:09:16
it looks like you're having a great time plus you've been on some amazing 00:09:19
simulators and really experienced space yes and i learned how important 00:09:22
communication and teamwork are in space travel 00:09:27
here's into the a dr d got it i'll be right back with a new one 00:09:30
for an astronaut to be successful you have to have the proper training 00:09:34
that's right there's a lot of practice practice and more practice 00:09:39
don't forget astronauts have to be physically fit 00:09:43
eat a healthy diet and also practice practice practice 00:09:46
we also learn to avoid spacewalks during solar storms 00:09:50
radiation is a big problem in space 00:09:55
here is the antenna do you have any instructions for installing it 00:10:00
affirmative space is a harsh environment so astronauts not only need protection 00:10:04
from radiation but also from the extreme temperatures 00:10:08
of space and from micrometeoroids 00:10:11
installation complete bianca do you have the order of switches for the 00:10:23
reactivation of the antenna roger okay trios detectives we have to 00:10:26
focus on our task here look forward to reading your research 00:10:31
report goodbye from space camp it's amazing it looks like we were 00:10:34
learning some of the same things yes we learned about special materials 00:10:38
used to protect both people and spacecraft from radiation 00:10:41
like polyethylene you mean plastic bags and we know the galactic cosmic rays are 00:10:44
a real problem we also learned how astronauts meals are 00:10:49
planned based upon calorie count in the food pyramid 00:10:52
let's not forget what we learned about unmanned missions the future of the 00:10:55
space program depends upon robots preparing the way for people 00:10:58
wouldn't it be cool if we all became astronauts and worked on a mission 00:11:01
together sure as long as bianca isn't the 00:11:04
commander she would make an excellent commander 00:11:06
and plus now she has more experience than any of us you're right 00:11:09
it would be pretty cool are you going home 00:11:13
i think i'll go for a run great i'll run with you 00:11:18
okay i'll run too catherine prepare to be blinded by my 00:11:22
pure speed 00:11:27
the nasa science files was made possible through the generous support of bush 00:12:30
gardens sea world and nasa langley research 00:12:35
center's aerospace vehicle system technology office 00:12:38
