Hello and welcome to STEM Job or Not.
I'm your host, Christopher Williams.
We've compiled a list of careers.
Put them on the board and it is your job to figure out which is a STEM job.
Are you ready? Yes. Yes.
Which of these is a STEM job?
(bong)
Astronaut?
Is astronaut
correct?
(ding)
Astronaut is definitely a stem job.
The astronaut corps is made up of an amazingly diverse
group of people with equally diverse backgrounds, including pilots,
engineers, medical doctors, and even a veterinarian.
There is one higher answer on the board.
Do you have a guess?
Scientist?
Is scientist on the board?
(ding)
Absolutely.
Scientist is a STEM job.
The S in STEM stands for science.
But scientists can include a wide range of jobs, including astronomers,
botanists, chemists and paleontologist.
Those are definitely STEM jobs.
But not all STEM jobs are scientists or astronauts.
We're going to find out which of these are STEM jobs, and which are not.
The answer might surprise you.
We'll be right back after this, Is STEM in 30!
(Upbeat Music)
Hi, I'm Marty.
And I'm Beth.
As you can tell, we are taking a deep dove into careers, many of them unexpected.
But we will stitch them together to give you a complete picture
of who and what a stem job is.
We mentioned astronauts and scientists
as STEM jobs These are pretty self-explanatory,
but not all STEM jobs are scientists, mathematicians or engineers.
To help us learn about these unexpected STEM jobs, we are going to be joined
throughout the episode today by someone who has one of these jobs.
Randy "Komrade" Bresnik is a United States
Marine F-18 pilot and NASA astronaut.
He flew on space shuttle Atlantis on STS 129
and served on ISS expedition 52/53
and was the commander of Expedition 53.
He has conducted five spacewalks and has traveled over 6 million miles in space.
Please welcome Randy "Komrade" Bresnik.
(Upbeat Music)
Komrade, thanks for joining us today.
I'm always happy to join you and Beth.
Marty, thanks.
Komrade, tell us a little bit about the different types
of astronaut training you have to go through.
Well, there is a lot of training.
First, you got to learn how to do public speaking,
which you know is not something all of us are all that familiar with.
We had to learn how to operate space systems on space equipment.
We have to learn how to basically do plumbing in space.
What is to take out the trash in space, vacuum in space.
We have to learn orbital dynamics.
We have to fly to a space station or fly to a spacecraft.
We have to learn how to fly where there's no atmosphere in which the wings of it.
You had to learn different languages to be able to talk to our partners
There's such a myriad of things we get to do.
It's it's it's really neat because it never gets old.
There's always something new.
Komrade, how many people does it take to support all of that training?
Thousands. I can't tell you.
You know, for every astronaut,
you know, that goes to space, how many tens of thousands of people
that go into making that happen it's from everybody that, you know, designed
the rocket to building the rocket, to assembling it, to launching it.
That's one side.
Then there's the scientific experiments that we do.
So one has to think of the experiment, you know, get it, approve, design it
so it can operate space, train us to do it, and then go do it in space.
There's the the people that work in the food lab.
They give us the food to eat
because you can't take up your stuff from the from the store all the time
because it has to be able to be stored for a while.
And so we have people that, you know, go ahead and make sure our food is ready.
And also the fact that when you go to store foods heavy.
It has water in it.
So they dehydrate it and,
all we do is actually rehydrate it when we're up the space station.
There's folks that work in mission control.
24/7, you know, the entire time the space station's been out there now
21 years, continuous human presence
an entire flight control team, of all the disciplines it takes
to make sure the space station can operate.
And a flight director they're there 24/7 365 days a year.
They're always there and they have people that back them up.
That's just a small, you know, smattering of folks
that make it possible for astronauts to work in space.
You have to go through
some very specific training and some of it is in an airlock simulator.
Can you tell us about that?
So spacewalks are some of the pretty much the most dangerous stuff
we do when we're on a space station mission
other than leaving Earth and going back to Earth.
So while we're up there during a mission going outside in the spacesuit,
which is your own personal spacecraft, it has to give you air to breathe, scrub
the CO2, keep you warm enough when it's cold and cool enough when it's warm.
It's the most dangerous stuff we do.
And so we have a fully mocked up airlock down here in the Johnson Space Center.
It has all the exact same hardware.
The only thing it doesn't have is no gravity.
And so we get the actual suits in there.
We get the same. It's going to be, you know, suiting someone up.
The suits and crewmembers should be getting in the suits,
and we practice
call prep in post
preparation for the EPA and post Eva.
Comrade, how much trust do you have in your spacesuit?
And do you ever think about the people that made it?
Oh, it's it's complete trust.
It's no different than trusting an airplane.
You're going to get to fly or a rocket ship, and it's just a lot smaller.
It only weighs 300 something pounds.
So when you see those pieces of equipment and you visit the companies
that make them, you're just very thankful for all those folks who are experts
in that one particular,
you know, system that allows you to have these repeatable EVAs and do them safely.
It's amazing.
Those people are just absolute artisans with that piece of equipment.
Space suits have come a long way since Alan Shepard's flight.
They have to be strong enough to stand up to the rigors of space,
but flexible enough to allow astronauts to do their jobs.
They have
allowed humans to walk on the moon,
fly untethered in space,
and assemble the International Space Station.
But one of the STEM jobs you might not think of
are the seamstresses who built the suits.
They have been so important
that their story will be told in the new Destination Moon Gallery
at the Smithsonian's National Air and Space Museum.
Their story starts with the earliest space
flights and continues today.
My name is Joanne Thompson,
and I worked on the space suits for Apollo 11.
Being in the room, sewing, it was very intense.
The gloves that I worked on were very small pieces,
and we had to meet a tolerance of a 32nd inch of an inch in most places.
So everybody was trying to do their best because
we knew a man's life depended on it.
I did have to sacrifice a lot of time with my family.
I had two small daughters, so yes, it was difficult.
Occasionally we would get to meet the astronauts
if they'd came to the plant to have a fit check.
Oftentimes they gave us autographed pictures of themselves.
They talked with us and answered questions.
It made the job a lot easier because now we met the guy that's going to wear this.
It made our job so very real.
And when I look at the moon these days, I remember, wow,
a man was up there with my gloves on.
My name is Amy Ross.
I'm the lead spacesuit developer at NASA's Johnson Space Center.
Well, the space suits
today are going to be both different, but also very similar
to the Apollo spacesuits.
Some of the basic principles of keeping someone alive when you go to space
are the same today that we're duing Apollo and we learn those lessons from them.
But we are doing different things and going different places than Apollo did
with a spacesuit.
For example, we're going to the South pole of the moon,
where they have lunar craters that are forever in shadow.
So they're very cold.
And we've never designed spacesuits to go in places like that before.
And then also because we're going to be staying for longer periods of time
on the moon, months rather than days, our spacesuit needs to be much more durable
and much more mobile to address the different situations you might find.
For example, if a lunar rover tire needs to be changed,
or if you have a crew member
who gets injured and that you need to help,
then we need to be able to do those things as well.
Another part of training astronauts do
is underwater in an enormous pool.
The pool is 202 feet long and 102 feet wide.
It's 40 feet deep and holds
6.2 million gallons of water.
To put that into perspective.
An Olympic swimming pool is 164 feet long and 82 feet wide
and about ten feet deep and holds 660,000 gallons.
So the Neutral Buoyancy Lab would hold over
nine Olympic sized swimming pools.
Or it would hold 2,348,485 kidie sized pools worth of water.
It contains full scale mockups of the International Space Station
and in the past has had full scale mock ups of the space shuttle
payload bay and the Hubble Space Telescope.
Those divers
(ding)
are a vital part of the training,
but not the only job that prepares astronauts.
Beth got a chance to visit the Neutral Buoyancy Lab in Houston, Texas,
and learn a bit more about the team of people
it takes to train astronauts for spacewalks.
(Upbeat Music)
I'm in the neutral buoyancy lab at the Johnson Space Center in Houston,
and I'm joined by Travis Fitzgerald, who is the chief training officer here.
Thank you so much for being here with us today.
Happy to be here.
What is this?
Looks like a great big pool.
Travis, what's going on?
Well, that's a that's actually exactly what it is.
It's a great big pool that we use to train the astronauts on how to do spacewalks.
We'll actually put them inside spacesuits and have put them down in the water.
And the benefit of the water is it gives them the ability to be neutrally
buoyant, hence the name of the building and allow them to kind of practice
what it's like actually being in space and without an microgravity environment.
Do you want to tell us what neutral buoyancy is?
It's not just floating.
Right, so, well, neutral buoyancy in terms of the water is that
you are at a point where you don't float and you don't sink.
OK, so you stay exactly where you are.
And that kind of replicates what it's like in microgravity
when you're outside on the space station.
That's the best way we have Aside from some of the airplanes
we have that do parabolas, but we only get like
ten to 20 seconds of microgravity in that environment.
This allows us to do an entire, you know, six hour run in the spacesuits
to get practice handling the equipment and actually doing the maintenance
as required in the space walk.
And the astronauts aren't alone in the pool?
Right, so we've got the two astronauts in the pool in suits,
and then they've got a whole host of divers down there with them.
Just in your normal scuba gear that are watching them, making
sure they're safe,
that are carrying their tools around and handing them tools when they need it.
And also for some things like when we broke up
where the space station is, the divers will actually say,
OK, you're going to translate from this part to that part.
You can't actually do that in the pool.
So we're going to pick you up and swim you over to this next part and put you on.
How many people does it take to run a day, a dive here?
A lot.
It's actually working in the pool
and up in the control center and all that.
It's probably 40 or 50 people doing this in addition to all the support personnel
that it took to schedule it
to prepare everything, get everything ready to do one run.
Thank you so much for joining us today.
This was really fascinating.
Well, I'm happy to be here.
NASA's astronaut, Mark VandeHei,
has spent a long time in space.
We got a chance to work with him after his first mission
to the International Space Station.
Since then, he has gone back to the station and has spent
355 more days in space.
He helped us understand
the science behind how the divers manipulate the buoyancy of the suits.
But not the astronauts In the suits.
(Upbeat Music)
We're joined by NASA astronaut Mark VandeHei.
He spent six months on the International Space Station and did four spacewalks.
Mark, how do you train for a spacewalk on Earth?
On Earth we use one of the largest pools, if not the largest pool on the planet
in the Neutral Buoyancy lab.
It's 40 feet deep, 100 feet wide and 200 feet long
with a full scale mockup of the exterior of the space station,
which is where we work.
Now, we actually got a chance to see you do some of the training
in the Neutral Buoyancy Lab.
And so we've got an experiment here we want you to help us
with to kind of learn how that works.
So what we have here is just a simple bottle filled with water,
and we have put a ketchup packet inside now.
Right now there's a small air bubble inside that ketchup packet.
And Mark, if you give this bottle a squeeze,
we will increase the pressure in that bottle and we'll see what happens.
That ketchup packet is going to sink down because we've increased the pressure
inside the bottle.
That air bubble gets smaller, increases the density, and it goes down.
Now, if you let go of the pressure, it'll come back up.
And in the neutral buoyancy lab,
that ketchup packet would kind of float in the middle
because you've got it so it's not going down
andIt's not going up, it's just floating there in the middle.
Mark, how does this compare to the training in the Neutral Buoyancy lab?
So if you imagine this ketchup packet being an astronaut in a spacesuit
to get that person to be neutrally buoyant,
to stay at the height that we like, we actually have divers
that stay around the astronaut who's training,
and they'll add weights to different parts of the spacesuit to change the mass
associated with that system of the astronaut.
And the suit Mark, when you're in the pool, the suit floats, but do you? No.
No. In fact, that's one of the things that makes that training sometimes
very uncomfortable.
You're basically in that space craft of the suit riding along inside of it.
So if you're upside down, the suit floats nicely, but all of your weight
to be sitting on your shoulders as you're upside down.
And how does that compare to an actual spacewalk?
Is a spacewalk more comfortable?
The spacewalk is more comfortable once you get over the sensation that you're
250 miles above the earth with nothing between you and the Earth but the visor.
In fact,
that's one of the things we have to train for
because I was used to having to overcome water resistance in the pool,
but in space,
once I started myself moving,
I didn't have to keep adding force to keep myself moving.
Nothing was going to stop.
Me Now, this is an experiment that you can do in your classroom.
You can do some Cartesian diver training, and all of the other students
will have to Ketchup.
The food the astronauts eat requires a team of people to prepare
to send into space scientists, technicians, chefs,
(ding)
people to package it,
and people to figure out how to keep it good for long periods of time.
Marty got a chance to visit the Space Food Systems Laboratory at Johnson
Space Center to learn more about the food
the astronauts eat in space.
(Upbeat Music)
I'm at Johnson Space Center in Houston, Texas, joined by Dr.
Grace Douglas, lead scientist in Space Food Research.
Tell us what goes on here in this lab.
Food for the International Space Station is made here or packaged here.
We also do research for future exploration missions.
OK, so something like
this is food that's been prepared here to go to the International Space Station.
How does this work?
The foods are prepared here and then freeze dried
and then they're packaged so that they can easily be consumed in space flight.
So in space flight,
they be rehydrated through this septum adapter
and then they can just cut open the package and eat it.
So this works great for the International Space Station.
It's very quick to prepare, which they like
because they're very busy on the International Space Station.
As we go into deep space, though, these foods have some limitations.
So right now on the International Space Station, they need about a shelf
life of about 18 months to two years.
As we go further into deep space and especially to a mission to Mars,
we need a shelf life of about five years.
And you're actually kind of paving new road here because there's not anybody
that makes food that lasts for five years right now.
If you go to the grocery store
now, there isn't really a need for that because we have cold storage.
For one thing, cold storage is something we don't have on
the International Space Station,
and it's something that we might not have even for these long duration missions.
It's a high resource use item and resource use in space flight.
They always want us to reduce it.
We get requests pretty often to try and reduce the weight of our food system.
This was the first shuttle packaging for the freeze dried foods,
and it's a hard plastic and we had to reduce that.
Oh, wow.
To continue the missions because as the cruise grew in the mission
lengths increase, this was just too much mass, too much trash.
And so now we have this very lightweight
and flexible pouch that can be thrown away pretty easily.
How important is it that the astronauts like the food?
We always have to be concerned about that when we go into space flight.
So we end up having a limited variety food system.
We have to make sure that that food is food
they want to continue to eat throughout an entire mission.
It's not quite true what they say, that if you're really hungry, you'll eat
what's there.
You will eat what's there, but probably not enough to maintain your weight.
Depending on what you're choosing to eat you might not be getting
all the nutrition needs.
We need to make sure that the variety
that's there, the crew is able to choose foods
that they like during the whole mission if they exercise
and if they eat the calories they need, and if they maintain their vitamin
D status, they can actually maintain their bone
and muscle mass, which is really important for a long duration.
Food is so important to crew
not only physical health, but psychological health food
in all situations of isolation, confinement, exploration
becomes very important and critical to crew cohesion.
And, you know, the ability to eat together
and consume meals that they enjoy and have meals that are special meals,
all impacts and benefit their psychological health.
Cooking requires a lot of the same skills used in a science lab.
You have to follow very specific
instructions, measure and weigh things accurately
and make sure you're using the proper equipment.
The big difference
is that in the science lab, you probably shouldn't eat your results.
We wanted to share this recipe from our friends
at the Space Food Systems Laboratory at Johnson Space Center for you to try.
This is JSC's recipe for mac and cheese.
Following
a recipe like this is very similar to following the step by step guide.
You would have for conducting an experiment.
Pause the video right now, or scan the QR code on the screen to get the recipe.
And let us know how it turns out.
In order to send food into space, there are some special considerations.
You can't just cook up mac and cheese and put it in a plastic container.
Here's a delicious food chemistry experiment
that you can try at home.
(Upbeat Music)
This is our friend Drew.
He's going to show us how to make strawberries spaceworthy.
People need to eat.
Even in space, but getting food into space can be tricky.
Food needs to be packaged to take up very little room, and it needs to be lite.
Water takes up a lot of space and is heavy.
So to make food space worthy, we removed the water.
To try Drew's space food experiment at home
you'll need strawberries,
a kitchen scale, a knife,
parchment paper,
a cookie sheet and an oven.
First place the strawberries on a kitchen scale and weigh them.
Drew's weighed about 8.5 ounces.
Next, say your oven to
200 degrees Fahrenheit.
Line your cookie sheet with parchment paper,
then cut your strawberries into 1/8 inch thick slices.
Pop them into your preheated oven and set the timer for 4 hours.
After 4 hours, check them.
And if they're not quite done, use a fork to flip them over
and let them bake another 30 minutes.
Once they are dehydrated, let them cool and weigh them again.
Wow. Now they weigh a lot less.
That's good for sending into space.
Another way astronauts
are able to share their experiences with the public is through photography.
Komrade got his start into photography from his grandfather,
who is Amelia Earhart's photographer.
Komrade can you tell us about the photography
project you did from space?
Every chance I can try to capture,
you know, the beauty of the world or the people that are in it, I do
and that led me to my second, you know, spaceflight where I had an opportunity.
I'm going to be living in space for, you know, six months aboard
the International Space Station for expeditions 52 and 53.
I thought, wow, I've got decades of
pictures from around the planet that are just absolutely gorgeous.
And so what I did was start a project hashtag One World, many views
where I had dots all over the planet that I could pull up.
And when I knew the space was crossing over,
I could try and get pictures of these same places on Earth.
And the whole idea of the project
was to go ahead and send out a picture side
by side on social media, the one from Earth and the one from space.
And my hope was that folks who were from that place would look at this picture
from space be like, Wow, this it's amazing what we look like from space.
How beautiful is that?
And how the people who had never been to these places on earth
look at the world from space. Be amazed how beautiful it was.
Look at the one from Earth because it made me think,
Wow, I'd love to go there, I'd love to visit, I'd like to see that for myself
and hopefully maybe bring the world a little closer by that project.
Astronauts are not the only photographers
(ding)
that NASA's employs.
Let's meet one of their amazing Earth based photographers.
I am Aubrey Gemignani.
I'm a photo archivist and photographer at NASA headquarters,
and I work with a team of photographers and editors, archivists and researchers
who help document launches,
leadership of NASA and lots of other historical events.
My dad gave me his his old manual camera probably when I was about 11.
I just fell in love with it.
I just I just never stopped.
I pretty much took any photography class that I can take growing up.
So I went to a lot of summer programs
that had all kinds of art, but a lot of photography.
I worked in the lab printing pictures for a while,
but then I also went into sales and was selling cameras.
One of my favorite things to do is like students would come in
and I would go crazy telling them all the details about the manual cameras.
I love space.
I've always thought space, and NASA's really, really a cool thing.
So when the job opened up, I, I applied for it.
You know, I've definitely developed this, this thing
now where I like, I used to get really, really nervous beforehand
and it would kind of messed me up.
So so I started realizing that, you know,
anxiety and stress is just
another version of, of excitement, you know, and that I get to go
and capture images of these amazing events that not that many people get to see.
And so I just started trying to turn it into
you know, in my mind, this is super exciting.
I'm really nervous, but it's exciting, you know,
and that helps me a lot to calm down and sort of enjoy
the moment in photojournalism what you're trying to do is tell a story.
So as many ways as you can tell that story is, is what you're aiming for.
So it definitely makes it easier when we have more than one person
that's there because you can be in a lot of different locations at one time.
For example, like you want to show the crowd's reaction to something
or you want to show the launch
or you want to show it from out in the wilderness somewhere or from far away.
Or you want to show the administrator and and their reaction to what's happening,
something you learn along the way that you either got it
or you didn't when you do, yeah, it's satisfying.
It feels good that you got what you needed.
We know that NASA seems to think of everything
and that includes smells on the space station.
This may be one of the weirdest STEM
jobs that you have ever heard of: Smeller.
(ding)
George Aldrich is a chemical specialist at NASA's
White Sands Test Facility in New Mexico,
and while Smeller isn't his official title
he has conducted over 850 smell missions for NASA.
They have a volunteer panel of 25 people
whose job it is to smell things before they're sent into space.
George has been on this panel for 45 years.
He has even earned the nickname of Chief Sniffer and Nostraldamus.
It is a big deal.
So much so that in the 1970s the Russians had to abort a mission
shortly after liftoff because of a bad odor in the capsule.
NASA uses humans instead of dogs or electronic noses
because they help better predict if something will impact an astronaut.
NASA has developed a detailed procedure to have smells
from the panels, smell different things and give them a rating.
While Aldrich volunteers for these tests his official role is to test
the toxicity of objects before they go into space.
They check almost everything down to the shaving cream the astronauts use.
Komrade, thank you so much for joining us today
and helping us see all of these unexpected careers at NASA.
Well guys,
Beth and Marty, as always, it's a pleasure to join you all.
There are so many opportunities at NASA.
Whatever you are interested in, there's something in human spaceflight,
or or even non-human spaceflight, robotic spaceflight
that it's a precursor for the human missions that you can be involved in.
We've got veterinarians who are astronauts.
We've got, you know,
music musicians that are now astronauts.
And when you think about going to the moon
and going to Mars and these long, longer flights where we're not going to be
living here on Earth, we're going to eat all kinds of people.
Do we need a psychiatrist on the artist mission to the mark?
Do we need a plumber?
Do we need somebody that, you know, has varied
skills in all kinds of areas that we haven't thought of yet?
Do we want to have a poet on board?
You know, we've got all kinds of opportunities now and in the future.
So whatever you're interested in, you know,
follow that passion, get educated in it and see where it takes you
because it's something that we can use maybe on planet and certainly
something we can maybe use off planet.
So as always, thank you all for allowing me to join you.
Always watch STEM in 30.
Let's check back in on our game show
and see how we did.
(Upbeat Music)
Let's
take a look back at our board to see how you all did.
We kenw Scientist an astronaut but you also got smeller,
seamstress, chef,
photographer, and scuba diver?
But those aren't all the stem jobs out there.
STEM jobs can also include writers, lawyers, artists,
psychologists and teachers.
So remember, no matter what your passion, follow it.
You may end up working for NASA or at the National Air and Space Museum
with Beth and me.
Or the National Museum of African-American History and Culture with me.
Tell us what your dream job is down in the comments section.
And if you enjoyed today's show be sure to follow STEM in 30 on Facebook
and Twitter and subscribe to the National Air and Space Museum's YouTube channel.
And remember, there are a lot of different STEM jobs.
What will you be.
