We're going back to NIAC this week on Planetary Radio.
I'm Sarah Al-Ahmed of the Planetary Society, with more of the human adventure across our
solar system and beyond. Last week, I shared some fantastic conversations from the 2023
NASA Innovative Advanced Concept Symposium,
or NIAC, which was held in Houston, Texas. In this episode, you'll hear from more NIAC fellows
about their big ideas for the future of space exploration. You'll also hear my interview with
Michael Point and John Nelson, the NIAC program executive and deputy program executive. Then
we'll check in with Bruce Betts, our chief scientist for What's Up, and we'll learn more about his favorite space conferences. If you love planetary radio and

The NASA Innovative Advanced Concept Program
cultivates groundbreaking ideas with the potential to revolutionize NASA's future endeavors.
I took a trip to this year's annual NIAC Symposium, held from September 19th to the 21st.
It was hosted in the Hilton Houston NASA Clear Lake Hotel in Houston, Texas. For three days,
I got to host the event's webcast and meet the people
behind the proposals. The NIAC program supports a wide range of mission concepts and technologies.
For a refresher, NIAC encourages submissions from a broad spectrum of academic and commercial
institutions. NIAC grants fellowships through phases one, two, and three. Each step gets even
more competitive and awards the NIAC fellows and
their teams more time to explore their ideas in depth. Last time, we heard from the teams
proposing ways to build on Mars, explore Saturn's moon Titan, and build new telescopes that can
expand our understanding of the universe. This week, we'll explore new ideas for melting our
way through the icy crust of ocean worlds, how to make medicines for astronauts in
space, and how to glide through the skies of Venus like a manta ray. But first, let's hear
from Mike LaPointe and John Nelson, the NIAC program executive and deputy program executive.
I got to talk with them on the third fantastic day of the symposium.
We have here Mike LaPointe and John Nelson, the NIAC program executive and deputy program
executive.
Thank you so much for talking to me and also for inviting me to be here.
I've wanted to be at NIAC for quite a long time, so thank you so much.
Thank you for joining us.
We really, really appreciate you being here and interviewing our fellows and just participating
in the interviews and sessions as well as the programs.
Thank you.
I wanted to ask you first, actually, because I know that you were a NIAC fellow twice over.
What is it like now moving on from that role
into a place where you can now enable the dreams
of a next generation of NIAC fellows?
As you can tell from all the energy in the room,
this is such an innovative community
that it's just awesome to be here
and have the privilege of actually running this program with John.
It's just outstanding.
It's fun proposing because you have these ideas and you want to see them come to fruition, to be here and have the privilege of actually running this program with John is just outstanding.
You know, it's fun proposing, you know, because you have these ideas, you want to see them come to fruition, but it's even more fun when you get to see the broad range of ideas that everybody
brings to the table. It's just incredibly exciting. We've seen so many amazing proposals over the last
few days, but I wanted to ask you both, what do you think were the standout moments so far during the symposium?
That's an unfair question.
We like to say that we don't have favorite children within NIAC, but we do sometimes.
And I know I love Edward Balaban's work with the Fluidic Telescope, for example.
But actually, this entire class of 14 Phase I's that we have is incredibly strong.
And obviously, the Phase IIs are making great progress. So that's one that I'll call out.
But yeah, they're all fantastic.
I guess it is a bit of an unfair question.
We don't want to play favorites.
But what about you?
I agree with John.
I think the presentations have been really spot on this year.
I really have enjoyed the keynote speakers.
I think they've done an outstanding job just bringing the energy to the room that we hoped
they would. And it's just been a really fun symposium so far.
Yeah, I was having this conversation last night. We were at a women in science conversation mixer.
And we were talking about all of the different kinds of symposia and conferences that are
involved in the science community. And how the scale of this, this kind of small community,
allows it to feel kind of like more of a family reunion.
You get to make these really deep connections with people, and that's been my personal favorite
part.
This is an interesting moment.
We heard from Bobby Braun the other day that there was a moment when NIAC ended and then
began again, and now you're building this robust, new generation of NIAC fellows.
What do you see the future of the NIAC program becoming in, say, 10 years?
Well, there's a lot of support within the agency.
You know, as John likes to call it, we're NASA's dream shop.
And I think there's a definite place for that in any agency, but in NASA in particular.
I mean, people expect us to be doing these future missions, you know, to look beyond Artemis even
and look down the road and see what are we going to be doing 10, 20, 30,
40, 50 years from now.
You know, where are we headed?
And these are the folks, I think, that are defining the technologies and the missions
that we're going to be looking at down the road.
So I think we're a robust program.
We have a lot of support within the agency, as you heard from Administrator Nelson and
Pam as well.
And so I think there's a bright future for NASA.
You know, obviously, it all depends on budgets and such. And, you know, we're always looking to increase and improve.
But I think there's a very strong, bright future ahead for NIAC.
I think something that's really interesting about it is, I don't know how many of you out there on
the internet know this, but the NASA budget is maybe 0.5% of the federal budget. And NIAC is
a smaller part of that. So with that amount of funding, you're seeing all
of these amazing technologies pour out. So anything that you can do out there to try to
support these programs is very much appreciated. It makes a big difference. And that is my next
question. What can people out there online who are watching today do to support the NIAC program?
What you're doing now, participate. We've been looking at the numbers of the folks that have joined us online,
and we're extremely happy to have so many people join us.
Come participate in symposia and propose.
Send us really good ideas.
We do capture the imagination of the public around the world.
We're very aware of that, and we don't want to change that.
We want to only that. We want
to only expand the program. And we're always looking for ways to reach new communities and
new people. In fact, you're going to hear talks this afternoon about our commitment to diversity,
equity, inclusion, and access. And we're looking for ideas there, too, of ways we can better engage
folks. So I encourage everyone to please get involved in NIAC.
The more diverse crowd we have, the more ideas we can put together,
the more wonderful new innovations we can come up with.
I'm sure that right now we have some younger folks that are in the audience,
some aspiring scientists.
What advice would you have for the people who want to propose to NIAC but
don't even know how to begin right now?
First option is, of course, come up with a good concept, something that we've
done before.
We have a NIAC website that's publicly available that lists all of the studies that have been
funded since 2011, actually.
They're all online.
So you can get a sense of what NIAC funds in terms of technologies and ideas and concepts.
Wide open. Any ideas are welcome.
But there's also on the website opportunities, key dates on how to propose, ideas on how to write proposals.
In addition to NAC, there are opportunities within STMD for additional opportunities for funding and proposals.
So there's just a wealth of information on our website as well as the STMD website on how to look for these kind of activities.
John?
I'll amend that and say not only do we have descriptions of all the projects going back
for this iteration of NIAC, on a non-NASA website through ESRA,
you can still access final reports going all the way back to 1998.
So please, yeah, learn about what we funded in the past,
understand the kinds of transformative concepts that we're looking for, and, yeah, learn about what we funded in the past. Understand, you know, the kinds of transformative concepts that we're looking for.
And, yeah, get involved.
And as we did see in previous talks, some of these technologies do become the really cool innovations.
I am personally in love with the Ingenuity Mars helicopter.
And, of course, we're going to see other things like the Dragonfly copter going to Titan.
So these things make a big difference.
Other than Ingenuity, which is an example, I'm just, I'm mind blown by, I can't believe how many flights that thing has gone through.
What other NIAC technologies in the past have made a huge impact on our current missions
to space?
So again, NIAC is a program that looks very far in the future.
So we're just seeing these things coming into fruition now, obviously.
So one of the things you mentioned earlier was the CubeSats that became the Marco Missions A and B,
which gave communication capabilities to the Mars orbiter as it was flying out to Mars.
That started as a NIAAC concept of, you know, instead of taking these small little CubeSats
and putting them in orbit in the last two weeks, how can we really make these deep space capable?
And so that grew into a JPL program due to the Marco satellites.
these deep space capable. And so that ruined a JPL program due to the Marcos satellites.
We had a phase three NIAC with Carnegie Mellon University, who is teamed with Astrobotic
now.
They were looking at lunar rovers to autonomously drive around lunar pits and craters, looking
over the edges without falling in.
The software that they developed for that is actually going to be used on a Viper mission
later on, which is really cool.
We have a University of Arizona CATSAT going to be flying either later this year or early
next year that started as an AI program to do 5G communication capability from a small
CubeSat in orbit.
So there are a lot of different examples along those lines.
I think we're starting to see spin-offs.
We're starting to see transitions coming forward.
A lot of these still remain very far in the future, of course, and we're excited to see
where they progress from there. Yeah. So I'll build on that a little bit. So on Red
Waker's work and the work that was done by Wooder Green and others at Carnegie Mellon,
that's an interesting one because when we first funded it, it was NIACI to think about looking
into lunar pits. That was 2011, 2012. Now it's not. And now it's actually going to the moon.
So we're starting to see that even just a decade later,
which is great. And I'll also add
to that that some of the successes we've seen
are not only
infusions into space missions
and not only inspiration of
other space missions, but some terrestrial applications
too, which are equally important.
So you've heard from
Lynn Rothschild.
She had a phase two called Microtexture, looking at
innovative ways of growing habitats on Mars based on
fungal mycelia.
Well, that work was done in cooperation with a group in
Cleveland that has looked at using that technology in
Africa for refugees.
And we've had a few other examples like that.
And we'd love to see that, and we're very proud of that as well.
And that's a great point.
This is a NASA conference.
NAHEC only takes proposals from people in the United States,
but as we've seen with the Artemis Accords,
there's so much interest in all of us working together to go to space
to make this an international effort.
And if you're coming to us from somewhere outside
of the United States, there are so many ways
that you can get involved with your space agencies as well.
But I really wanted to thank both of you for joining me.
And for anybody who wants to learn more about NIAC,
you mentioned the website earlier.
That's nasa.gov slash NIAC.
So I'm here right now with Teresa Benyo.
You are from NASA Glenn Research Center.
You proposed yesterday a really cool idea for how we can actually explore some of these icy moons out there.
I know a lot of us are really intrigued in the idea of trying to find life elsewhere in the universe,
but it might be somewhere in our own backyard.
And even if it's not, we need to find a way to get beneath the but it might be somewhere in our own backyard. And even
if it's not, we need to find a way to get beneath the ice on Europa and Enceladus. So what is your
idea? Oh yeah. So we're working on a autonomous robot that would either melt through the ice,
drill through the ice, or do a little bit of both and use a hybrid fusion fission power reactor to make it all happen
and get ourselves down underneath and explore the ocean world underneath there.
So you're using this technology, lattice confinement fusion. What is that just more
broadly for people who are intrigued to learn more? Yeah, sure. Lattice confinement fusion
is a lattice of metal atoms that contain deuterium inside of it.
And with a trigger like an electrical current or an X-ray or a photon beam, it will impart energy into the lattice system. electrons from the metals will create like a barrier between the two positively charged
deuterium atoms and eliminate that Coulomb barrier that will, you know, not want them to go together.
So they look neutral to each other and with enough kinetic energy, they'll fuse together.
It's a really cool technology, but then, you know, you got to get to that world. How much
ice are we talking about digging down through?
Because these shells could be very, very thick.
Yeah.
With Enceladus, it's estimated to be 30 to 40 kilometers.
So it could take many years to get down beneath the ocean there.
But once you get down there, just imagine what you could see once we finally get
into those oceans.
It could be amazing.
But I'm wondering, how are you going to communicate all that data you might gather
back to the surface? Yeah, that's a big challenge. We haven't worked through the details on the
communication right now, but we can use fiber optics. We can use different repeaters to rally
the data there. We're still kind of working on those on those
details of that. Yeah that is a real challenge trying to communicate back
through that ice trying to power all those little transmitters all the way up
and then of course you might need some kind of a spacecraft above to
communicate all that data back to Earth so that's a complex problem to have. Oh
yeah sure sure sure but one of the exciting things that I learned here
at NIAC is, you know, when we get down there, you know, what are we going to do and how are we going
to explore? And there was a group that has these swim, that's called swimmers. There's these like
little triangular pizza pie kind of shaped robots that, you know, could swim underneath and sense, you know,
detect all kinds of things down there and stuff. So I'm really excited about another group working
on that because I think that could really help with our mission. Absolutely. I mean, there are
so many people that have proposed some amazing research that we could do once we can actually
sample those waters. As we've seen with Enceladus, the fluids that are spewing out into space suggest that there's hydrothermal
activity, some kind of cool maybe undersea vents that could have life. But that's the next question.
Might there be life in those oceans that might be attracted to the heat of this technology or,
you know, what kind of interesting things might happen there? Yeah, that's true. Yeah, that's
something that could be very interesting. And who knows? I mean, we might have to go far
and, you know, that life might come out and seek the robot that's going to be warm. Yeah,
it's going to have to be warm to get through that ice. So yeah, that's exciting. We're probably
talking about like microbial life, not like full shrimp swimming through the seas of Europa,
you know. But even then, just a little bit of life in those oceans could completely
change the way we think of ourselves and our place in the universe so this is a
really useful technology yeah that's true yeah but we also have to be careful
because we don't want to damage any of the life forms that we encounter down
there so that's one of the other attractive things about our fusion fission
reactor is that it does not emit a lot of radioactivity from it. So that's another reason
why we're pursuing that concept. That's a cool idea that you can use nuclear reactions in order
to actually get down in there, but then hopefully not contaminate anything, you know. But I'm wondering how you're going to test this.
Are you potentially going to, say, Antarctica or some kind of ice sheet
and just dropping something in and see what happens?
No, Antarctica is a perfect place to test all this out.
And, yeah, eventually, you know, when we get to that point,
we would love to do something like that.
Are you envisioning, like, the shape of this spacecraft that you might be trying to use to drop beneath the ice,
or are you still just in the phase where you're trying to figure out the actual melting technology that will take us down?
Well, we do have some previous designs that were developed at NASA Glenn and also at NASA JPL.
So we're looking at both those concepts, and we would like to work with those a little bit
and maybe add a couple more things to it.
Like right now, the nose of the tunnel bot is very blunt,
so I envision some kind of blade, like a heated blade or even ultrasonic, maybe heated blade.
There's actually something that exists that helps cut frozen cakes that's an ultrasonic blade.
So we're looking at that, that too to enhance the existing designs. I know we've tried to
deal with this issue before when we've gone to places like Mars say and tried
to dig beneath the ground. We've had issues if anybody remembers the InSight
mission that mole was trying to get into the ground we don't know why it didn't
manage to do it but there was a lot of concern. What if it hits a rock or something? What would we do in this scenario to try to navigate
around obstacles within the ice that we might not be able to see from space? No, no, that's a very,
very good question. We haven't fully explored that possibility yet because, and we do estimate that the ice on Enceladus is very granite-like.
So it's kind of like a rock anyway.
But we can melt that rock, we think.
But yeah, no, that's definitely something that we need to keep considering
and make sure that our navigation system can process those kinds of things
and that we can navigate around those obstacles while we
get to the ocean below. I think what's cool about this too is that this is just a technology that
can actually allow us to get into the ice. But as we go, we might be able to take samples of the
ice as we go down, learn more about what it's made out of, how it might be different in the
different layers on the way down. Because there's so much we don't know about the source of ices on these moons, whether or not the water formed with these
moons or whether or not it was seeped out of the rocks later. There are a lot of mysteries we could
solve with these things. Oh, yes, definitely. I mean, we know a lot right now with the Cassini
mission, with the plumes that you mentioned, which means that there's like a really hot core to this
thing and the estimates of the ice crust, the thickness. But yeah, there's just, there's so
much more that you kind of need to be there to really explore and see how this moon was made
and what it contains. And so, yeah.
It would be cool to envision a future where we could pair this technology with something like
Europa Clipper or, you know, the Enceladus Life Finder mission that people are like thinking of
doing because we can learn a lot from orbit. We're on a long timeline here. So maybe in the
interim, this technology could allow us to drop a probe down there and then maybe taste those
waters a little.
Oh, yeah, definitely, definitely.
Yeah, we've followed the mission that's proposed.
It's going to do like what you're saying, orbit around Enceladus and, you know, check out the whole thing closer. And then a follow-on would be to actually, you know, find a good landing spot.
to actually find a good landing spot because we don't really want to land in the plume areas
because the velocities of those plumes
are estimated to be like 500 meters per second.
So it would be really hard for that robot
to fight that plume coming out.
Those kinds of missions are going to definitely help
this TunnelBot mission as well.
And what's really interesting about this
is a lot of the information we know
about the outer solar system is actually quite old.
We have not been back to Neptune or Uranus.
We have only been to Pluto once.
It's been quite a long time.
So potentially there are a lot of other icy bodies out there
that we could use this technology for.
I wish we had all the funding in the world
to go to every single world.
Oh, me too, me too. I mean, there's just so much still to explore out there, even though we've done
a lot so far. But yeah, it's just, oh, it's amazing what we could learn. I'm looking forward to it.
I know, right? I was myself very motivated by the first exoplanets that were discovered. So
now that we have so many of them, I'm so excited to be able to compare them to the things that we know and love here in our solar system. So thank you for ideating
on this technology. This is a huge problem that has been plaguing me since I was a child. How do
we figure out what's down in there? So thank you so much, Teresa. All right. Thank you very much,
Sarah. It was great talking with you. We'll be right back with the rest of my adventures at
the 2023 NASA Innovative Advanced Concepts Symposium after this short break.
Greetings, Bill Nye here, CEO of the Planetary Society. Thanks to you, our LightSail program
is our greatest shared accomplishment. Our LightSail 2 spacecraft was in space for more than three years, from June
2019 to November 2022, and successfully used sunlight to change its orbit around Earth.
Because of your support, our members demonstrated that highly maneuverable solar sailing is possible.
Now it's time for the next chapter in the LightSail's continuing mission.
We need to educate the world about the possibilities of solar sailing by sharing
the remarkable story of LightSail with scientists, engineers, and space enthusiasts around the world.
We're going to publish a commemorative book for your mission. It will be filled with all the best
images captured by LightSail from space, as well as chapters describing the development of the mission, stories from the launch, and
its technical results to help ensure that this key technology is adopted by future missions.
Along with the book, we will be doing one of the most important tasks of any project.
We will be disseminating our findings in scientific
journals, at conferences, and other events, and we'll build a master archive of all the mission
data, so every bit of information we've collected will be available to engineers, scientists,
and future missions anywhere. In short, there's still a lot to do with LightSail,
and that's where you come in. As a member of the
LightSail mission team, we need your support to secure LightSail's legacy with all of these
projects. Visit planetary.org slash legacy to make your gift today. LightSail is your story,
your success, your legacy, and it's making a valuable contribution to the future of solar sailing and space exploration.
Your donation will help us continue to share the successful story of LightSail. Thank you.
This is Lynn Rothschild from NASA Ames Research Center. You may have watched
her wonderful talk the other day about a mobile astropharmacy.
I got to ask you, what inspired this idea?
And why is this so necessary for our future out there in space?
Well, I can tell you the truth what inspired it.
I got encouraged by a pharmacist who had been thinking about this for a while, Phil Williams. He's part of our team from the University of Nottingham.
But the other way to think about this, and that's NASA's needs, that we have
astronauts who will ultimately get sick in space. And you can't take an entire pharmacy with you.
It takes up a lot of room. It's heavy. You don't know who's going to get sick or what they might
need or how much of it. And a lot of drugs just simply go bad. You can't leave drugs in your
medicine cabinet for 10 years. They just
don't last that long. So we started to think, well, the way to solve the problem is to just
simply make the drugs when you need them. But how are you going to manufacture these drugs in space?
It's a very complicated process even here on earth to make the drugs, to make sure they're safe.
What is your technique to do this? Because I feel like this is really clever.
What is your technique to do this? Because I feel like this is really clever.
Well, it turns out most drugs are or certainly can be made by living organisms.
And in fact, many of them are made by bacteria today anyway.
Your insulin no longer comes from a cow or something.
It comes from a bacterium that makes it for you.
And bacteria are very small.
So in fact, there are whole classes of drugs that are really easy to make in a bacterium
that are the ones that actually go bad the fastest.
These are ones that are based on proteins.
And they go bad in about six months, even if you refrigerate them.
So if you've got a two-and-a-half-year round trip to Mars, that's a no-go.
And so it's just ideal.
The easiest ones for us to make are
the ones that are the least stable. And so they're the ones that we're starting with. These are so-called
protein-based biologics. And this is really wonderful too, because there's so many reasons
we're going to need this. A, if we're going to send people to the moon and to Mars, we're going
to need to have drugs that last longer than six months,
because it's going to take a while to get there. But also, in the spirit of this conversation about DEIA we were just having, there might be things that we can do with this technology to allow
people who previously wouldn't be able to go into space to then have the medications that they need
to come along for the ride with us. Absolutely. But even on Earth, we have a problem in that
pharmaceutical companies,
it's no secret, want to make money. Of course, there are companies. And it turns out that in
the United States, an orphan drug is defined as having 20,000 Americans who need that drug.
20,000 is a lot. So we're doing exactly the opposite. We're worrying about very tiny numbers
of people, but they might need it
now. And so I like to think that that's a big application that we're going to have on the earth.
The pharmaceutical companies don't need to worry about making 100, 2 million doses. This is
something that in principle could be available for even one person who needs a particular drug.
Why should we ignore them just because their disease happens to be classified as an orphan drug?
I know that this has been a huge problem for us here on Earth. There are so many drugs that go
through shortages because we just simply don't have enough of them for people. And this is going
to be a major issue as we go to space as well. You never know what you're going to encounter out
there. Absolutely. Or one of the applications I hadn't thought about that was suggested to me by actually the Department of Defense, but it could be more
widely applicable, is antidotes for poisons. Now they're thinking in terms of warfare, but I started
also thinking, what about a snake bite? What if you had a kit to be able to make the anti-venom
right away? You know, wouldn't that be amazing? That could save a lot of lives.
Even though you can use a simple bacteria to do this, do you have to, say, create specific
bacterial strains that can make specific drugs and then bank them all together? How does that work?
So we don't know each other well enough for me to kick you, but there is no such thing as a simple
organism. Every organism has these capabilities to take DNA, read it, and make it into RNA, and then ultimately into proteins.
And these are the drugs that we're focusing on, the proteins.
So it is relatively simple to program these cells to make different drugs.
Now, because we need to then purify these, we ideally want the organisms to make them, these bacteria to make them, and then export them out into the medium.
Now, it turns out when we started working on this in phase one, we did so well in some of these drugs that it actually poisoned the bacterium because they were getting such a big dose of the drugs.
And so there are going to be alternate ways that we may have to approach this, or actually we may have to go with strains that are not the best producing for their own health,
but we just get enough for the humans, and that's good enough.
So I think that this is a really promising route.
Now, as I've been alluding to, we've been focusing on drugs,
but there are lots of other things that you can make in small doses.
Now, this may sound fun and trivial, but fragrances, flavors, you know, once you have this little tiny biological production system, there might be all sorts of things.
And so just, you know, in a funny way, imagine you're an astronaut a year from home.
It's like, oh, if I could only have that smell of coffee or chocolate or, you know, some cologne or whatever.
You know, wouldn't it be amazing?
Or a glue.
You need to glue something.
You can make a biological glue or, you know, or, or, or.
So wouldn't that be amazing if you had this little tiny bioproduction system?
So I really see that even though the astropharmacy is the real need that the agency has,
that there are a lot of potential
spinoffs from this. I'm flashing back to that moment in Star Trek Voyager where they ran out
of coffee and Janeway looks up at that nebula and goes, there's coffee in that nebula. No,
but really though, when you're out in space, it's these little things that we take for granted.
Absolutely. And one person's flavor that they miss may be not what the other person misses.
I personally am not a coffee drinker.
I'm a tea drinker.
And so what I may be lusting for after a year and a half in space might be a chai that you wouldn't even touch if you had a truckload in the driveway.
And so the beauty of these small personalized systems is you don't have to load something and imagine the astronauts are all one homogeneous
group because we're not. We as humans are all different and we have different needs. And so
if you can address the personalized needs, how much better that would be. And I was going to say,
kick me whenever you want, because there's so much about biology that I don't know. I studied
astrophysics. You studied a whole different branch of science. And I feel like that is
what's so awesome about places like NIAC.
We're coming together with our different disciplines to create these technologies that any one of us might not have thought of together.
Next year we'll know each other well enough for me to kick you.
For sure.
Well, thanks for joining me, Lynn.
And I really hope that this technology works because I feel like it's not only really useful for space, but so essential for what we
do here on Earth. It could improve so many people's lives. And thank goodness the NIAC
program recognizes these crazy ideas. Before I let you go, what are the next steps in phase two,
now that you've gone through this? What are your next big projects with this?
So there are all different aspects. There's the programming the cells to make more drugs.
And actually, there's even before that, doing paper studies to see how many drugs we, in principle,
could make on the astronaut med list, or maybe drugs that ought to be on it.
So what's the general utility? And then the actual technical of programming the bacteria
and then these alternate routes that I alluded to. And then we're kicking in with two wonderful
engineers, one who's a student who's applying to grad school right now and others and engineers
worked with them over the years,
and that is building a very tiny purification system
because we can't take an entire pharmaceutical industrial plant.
So I've challenged them into making this purification system
small enough that it would fit in two syringes.
I mean, really tiny.
And then, obviously, another step to this
has to be to check the purity of the drugs.
You know, we're certainly not going to promise the end of phase two to have something that you
could inject in a human. But it would be good to know how close we are. And then, of course,
we have to have this in a mission context. So, we have a doctor on the team, my colleague David
Loftus at NASA Ames, who's specifically looking at how you might activate the system in the event
of a solar particle event. And then, you know, finally, we also are doing a little bit of thinking about
these applications for non-NASA uses, as I say, and antidotes maybe to poisons, or maybe when
you're on a submarine or in a remote area or camping, or this is a supply chain issue where
you can't keep medication cold all the way through for years on end. You
don't need to worry about this supply cold chain anymore, which is something we became very aware
of during the era of COVID that our supply chains are sensitive. And so we're specifically working
on trying to make this system so it does not need refrigeration. And that also is a huge part of it,
which we haven't been pumping up, but I think it's ultimately a huge part of it, which we haven't been pumping up, but I think it's
ultimately a huge part of it. That's so cool. Very, very busy. I can't wait to hear where this
goes in the future. You've got a couple of years to ideate on it and maybe, fingers crossed,
phase three. We'll see. Fingers crossed. Thanks for joining me, Lynn.
The last people I spoke with at NIAC were Javid Bayandor and his amazing
group of grad students from State University of New York. I wanted to take a very special moment
to talk with this group of people here. Javid, thank you for bringing all of these amazing grad
students with you. Why did you feel it was so important to bring everyone who's on the team
with you here today? Well, of course, these are our future professionals, and it's extremely important
for them to feel and see themselves as part of the, you know, adventures that we go through to
develop the technology and all that. So this is part of their education. I hope it's a quality
education. I wanted to ask you, because this is my first time here at NIAC, can I get a show of hands?
Who's here for the first time?
See, every single one of you.
I love that.
That's fantastic.
So the project that you guys are all working on is something called Breeze.
I thought this was a really cool project because, as many of you know out there, one of the
priorities of the Planetary Dicatal Survey recently was the exploration of Venus.
And in order to do that, that is really, really complicated.
So you've created an interesting idea on how to do this
that is inspired by a manta ray.
Would one of you like to tell me who came up with that idea?
They're too young to remember.
Initially, I had two teams.
One was the robotic teams, and the other one was a mission team, mission development team.
And we were working on different planets.
And once we got to Venus, we realized that Venus has an extremely thick atmosphere.
And in order to be able to sustain flight in that atmosphere, we need to have a system
that swims rather than flies. So we thought, okay, so how about we use our manta ray in that environment and see how it performs.
Is this thing going to just be shaped like a manta ray, or is it going to literally flap as it soars through the clouds?
So it's inspired by manta ray.
It may not exactly do what manta ray does. It soars with the zonal winds and then
uses the flapping system to course correct and stabilize itself, but very rarely. So it's not
very energy intensive. Is this the reason why you decided to go with a kind of flexible,
inflatable craft so that it could do this kind of flapping motion? Who would like to take that one?
So, I mean, with an inflatable system, you have a really high packability.
And for a buoyant system, we're going to need a lot of volume to be, you know,
buoyant in that regime, maybe about 50 to 60 kilometers.
And so that's kind of like combining those two factors together.
Inflatable system made perfect sense.
I mean, there's been, balloons previously, and kind of adding capabilities upon that,
we can expand the mission scope from just a balloon that would be pushed by the winds.
And Javed, you just mentioned this, that you're going to be sailing on the zonal winds around Venus.
How does that work, and what is that going to allow you to achieve travel-wise around Venus? How fast can you move? For zonal winds, because they are a driving force
and they're really fast, especially at the altitudes of between 50 and 70 kilometers from the
terrain, we would be able to circumnavigate the planet in less than six days. So this would provide us with a unique
opportunity to see the dark side as well because you know if you send a drone or a robot to the
dark side you have to wait for about 120 days or 116 days before it can come to the light and you
know you may have lots of complications before you can restart the system. But this one can have enough reserved to go to the dark side and then basically show up in a couple of days on the other side.
And it provides a unique opportunity for us to do repeat measurements from areas that we are very interested in.
And, you know, any other drone or any other probe would be able to just do one maybe measurement at best.
But see, this is another challenging thing.
If you're going to try to be measuring again in the same location later,
you're going to need to know where you are on Venus, which is very difficult.
So how are you going to figure out the position of the spacecraft as you're going around the planet?
We're basically going with multiple approaches.
We can either look up or look down, basically.
So we would be going with terrain-based navigation, try to find landmarks and, like,
substantial features on the Venusian surface and be able to track those while we're flying.
Or we can look up into the stars and things that are always there.
Which is really useful because some of the main mysteries about Venus is, you know,
what kind of volcanism is
going on there? Is there lightning? Are all those things that we're seeing actually just
little bits of meteorites or something burning up in the atmosphere? We're going to have to
look at the dark side in order to learn these things, which is really cool. But my next question
has to do with just the nature of Venus itself. As many people know, Venus is kind of a hellscape,
right? To put it lightly. If you get down on the ground, crushing pressure, melting heat,
literally it rains sulfuric acid.
So what material are you going to be putting on the outside of this craft
to prevent it from literally melting on Venus?
We have done many material selection studies,
but the altitude which we have picked, as Dr. Meijer said,
about 50, 60 kilometers, which is very Earth-like.
So we might not even need to do that.
We might be just facing slight acidic environment.
But of course, we are working on layered fabric materials, and we are looking into coatings
which can prevent the weathering in the Venusian surface.
That's really cool.
We're going to need the technology to shield things as we're going into Venus.
That planet is so mysterious, despite being literally right next to us.
Concerning what you just mentioned, at the altitude that we fly, there is an estimation that the temperature and the weather may look very much similar to what we have here on Earth.
So, you know, we get to actually test that as well and see if any organisms, microorganisms
actually live in those altitudes.
Which is a mystery.
I know everyone is very puzzled by this potential detection of phosphine on Venus.
We need to know what's going on there.
There's so many things we don't know yet.
Was there water on the surface?
Was it Earth-like at some point?
And now it's Venus.
So I'm really glad that you guys are coming up with this technology.
I do have one last question to ask you guys.
What was your experience like here at NIAC over the last few days?
I can't ask every single one of you, but would any one of you like to speak on your experience here?
It was absolutely amazing.
It was so incredible to meet a bunch of professionals who are working in the field and developing these very intriguing and new concepts.
It inspires a great
new level of creativity and I've just loved making these connections. So it's been very wonderful to
be here. I feel very similarly. It's my first time here at NIAC and over the last few days I've met
so many amazing and passionate humans with so many beautiful ideas that could really help us
revolutionize the future of space travel.
And I'm glad to see you're all here.
I hope we see you again in future years.
I know I'll be back here at NIAC in the future as well.
If you want to learn more about any of the projects that you've seen here over the last few days,
or you want to learn how to contact teams like the Breeze team to suggest your ideas
or volunteer your time or work on the projects, go to nasa.gov slash NIAC.
That's N-I-A-C for NASA's Innovative
Advanced Concepts. This program is one that I think we really all should be a part of because
your ideas, their ideas, all of us together can really take this all to the next level.
Thanks, everyone.
I've done a lot of cool things in my time as a science communicator,
but getting to host a NASA symposium webcast was next level.
I want to thank the NIAC fellows for speaking to me
and for their dedication to advancing space science and exploration.
Thanks to everyone at the NIAC program office who let me be part of the event.
And a massive shout out to the AV and tech people at NASA 360.
All of you are awesome.
There are so many great space
conferences that are free to watch online. I've been tuning into these webcasts for years and
highly recommend them. They offer a great way to stay updated on the newest ideas and discoveries,
but they also let you meet the people behind the science. Now let's check in with Bruce Betts,
the chief scientist of the Planetary Society for What's Up. I want to hear what space cons he enjoys most. Hey, Bruce. Hey, Sarah, how you doing?
Back from NIAC. That was an adventure. Did you have a wild and crazy time?
Wild and crazy. I mean, as much as scientists can get. No, I mean, it was just a gauntlet of
really cool ideas.
And I don't know about you, but whenever I come out of an event like that, I'm always a little like, I don't know, emotionally enlightened, but mentally drained.
I'm just exhausted from too much thinking.
Yeah.
And like people.
Oh, it was a lot of people. But I got to meet Mae Jemison, so I'm not complaining.
You can check that one off.
Yeah. That's one of those life experiences there. And it was really beautiful. They had a talk on
DEIA at NASA, and there was a moment where Mae Jemison was up there and she was speaking with
one of the speakers up there who's an African-American woman who's blind and watching them bond together and talk about
how May's experience in life helped this other person become one of the DEIA coordinators for
NASA was just like such a moment. Just anytime you get behind the scenes and watch these people
and their actual interactions with each other, it's kind of like the magic of these conferences,
I feel. Or like watching sausage be made, but not in this case.
This sounds like a really cool moment.
Yeah, it was a cool moment.
I did want to ask you, because you've probably been to a lot more of these events than me.
I'm just kind of starting out with my going to conferences.
But what are your favorite space conferences and events?
Comic-Con, Planetary Defense Conference. I have a sweet spot. Sweet
spot in my heart? I don't know. That's one of my favorites because I've watched it grow and mature
in the field and mature over the last 20 years or so since they started holding them. And we've come
a long way in planetary defense and asteroid threat. And it's neat because it's the one conference that brings together all the different aspects
of the problem, even like disaster preparedness and assessment and trying to involve the political
side of it, but also the observers and the theoretical people.
And so it's a great mixture of all the aspects of a very weird, different problem
compared to most of what we think about in planetary science. And then just the solid
planetary-focused things, so DPS, Division of Planetary Sciences of the American Astronomical
Society, LPSC, Lunar and Planetary Science Conference, those guys. But there's so many others.
There's so many letters that just I could rain from the sky.
That's awesome, though.
I really want to go to all of these.
I've only ever been to now NIAC and the AAS.
I got to go one year.
That was a dream come true.
I really wanted to go to that, which is just as nerdy as it sounds.
And this was the AAS, American Astronomical Society.
Not to be confused with the AAS, the American Astronautical Society,
which is a whole different bunch of engineering types.
It's a lot of fun.
And it was nice being behind the scenes with those people
and nice to host a NASA webcast for the first time.
And I hope I get to go back.
So that'll be a good time in the future.
Cool, cool, cool.
Well, good.
Should we do a little bit of...
Random Space Fact!
Oh, that was a good one.
I can envision you flying down the highway on a motorcycle that just screams random space fact.
Wow.
What do you got for us, Bruce?
Mind blown.
That's what I've got.
But going from new tech to old tech, that works really, really well.
ended up doing the so-called Grand Tour, which lines up once every 175-ish years, where you can use one planet to get to the next and the next.
Voyager 1 did not.
And why did Voyager 1 not?
It went to Jupiter and Saturn, then headed off.
It's because they decided on a priority to get data about Titan as the one thick-atmosphere moon in the solar system.
And the way the orbits worked out, once you did that, you went flying off in different directions.
So that is why only one of the two visited Uranus and Neptune.
And they actually considered other permutations like redirecting to Pluto.
But the decision was made that Titan was the party.
I didn't know that. And I'm honestly glad that they made that decision because,
I mean, come on, Titan is so cool. Would we know how cool Titan was if they hadn't pulled that off?
That's an interesting question that would be interesting to learn. Certainly at the time,
we learned more. Titan also was a little shy and and so it was covered in smog, and they couldn't see the surface.
So, you know, that was a drag, but they learned a lot about the atmosphere
and what to do when they came back with Cassini and lit it up with a radar and infrared to see through.
So, yeah, Titan, cool place.
And Voyager's cranking out there is the fastest and farthest human made object well it's
fastest it's leaving the solar system they keep slowing down as the sun tugs at them as they go
yeah voyager cool it really is though i mean i know it's highly unlikely that any intelligent
creatures out there are ever going to find it but if they do how confused and awesome would that be
i mean we're only just beginning to send things into interstellar space i feel like that's a out there are ever going to find it. But if they do, how confused and awesome would that be?
I mean, we're only just beginning to send things into interstellar space. I feel like that's a big moment for us as a species. Yeah, we've made it. We still have a few
tens of thousands of years before we leave the solar system's gravitational effects,
but we've made it to past all those shocks and pauses and made it out of the
influence magnetic field. And it is, it's profound.
I think that is something that's interesting when people talk about Voyager.
Like a lot of people say that the Voyager spacecrafts have exited our solar system,
which I feel isn't entirely correct. Like they're definitely in interstellar space, but
they're still under the gravitational influence of our sun.
Yeah.
And they will be for a long time.
And that's typically how we kind of define the solar system.
So I too,
that's why I can't help,
but started explaining that,
but it's super cool because they're beyond the primary influence of the sun's
magnetic field,
which goes way the heck out there.
So we're actually into the space between the stars.
It's going to be so cool when we just have a whole bunch of probes out there measuring
interstellar space or someday, maybe, maybe, maybe we'll have little solar sails that go
out to other systems. I don't know how far away that will be in the future, but
clearly there are people at places like NIAC that are thinking about it all the time. So that's heartening, even if those
technologies don't work out. Yes. No, the future looks bright and dark if you're that far away
from the sun. All right, everybody, go out there, look up at the night sky and think about dog ears versus cat ears.
One night only, Smackdown.
Thank you. Good night.
