Okay, so picture this.
(00:01):
You're an archeologist, but you're not digging in the Earth.
You're digging in space, and you've just stumbled upon
like a perfectly preserved time capsule,
older than our planet itself.
Wow.
That's what we're talking about today.
Bennu, the asteroid that's basically,
it's like a cosmic window into the birth of our solar system.
(00:21):
Okay.
Welcome to Cosmos in a Pod,
the Space and Astronomy series.
Please like, comment, share, and subscribe.
So what makes Bennu so special?
Well, to understand that we need to bring in our expert.
So what's the big deal about Bennu?
Why are scientists so excited about this particular asteroid?
It's all about something we call pristine material.
(00:43):
You see, most meteorites that we find here on Earth
have gone through this fiery ordeal, right?
They enter our atmosphere, they get scorched,
they get altered.
But Bennu, it's been out there virtually untouched.
Really?
For 4.6 billion years.
Wow.
It's like a cosmic deep freezer,
preserving the ingredients
of our solar system's earliest days.
So it's like the original recipe.
(01:03):
Right, exactly.
Not like a burnt meteorite you might find in a museum.
Exactly.
This is like the raw ingredients,
still fresh from the cosmic oven.
Precisely, and that's exactly why NASA launched
the OSIRIS-REx mission.
Oh right, to grab a piece of it.
Yeah, to grab a piece of Bennu,
bring it back to Earth for analysis.
So we have some here.
We do.
It's like having a piece of the solar system's
(01:24):
birth certificate right here in our labs.
Wow, that's some seriously valuable cosmic cargo then.
But I'm curious, why go through all the trouble
of sending a spacecraft millions of miles
just to get a handful of space rock?
What secrets can Bennu actually reveal?
Well for starters, it helped us understand
the origins of our own planet.
Okay.
(01:45):
Scientists believe that Earth early on
was bombarded by asteroids.
Right.
And some theorize that those impacts
might have delivered water.
Wow.
The water that fills our oceans.
And maybe even the organic molecules that make up,
that are the building blocks of life.
Hold on, are you saying that the water we drink,
like the very essence of life on Earth
might have come from an asteroid like Bennu?
(02:07):
It's a wild thought.
That's a pretty wild thought.
But it is one of the most exciting questions
that scientists are trying to answer by studying Bennu.
And the samples collected by OSIRIS-REx,
they contain water-rich minerals.
These could hold clues about the source of Earth's water.
So it's like a cosmic detective story.
It is.
We're looking for clues on Bennu
(02:28):
to solve the mystery of Earth's origins.
Yeah, precisely.
And it's not just about water.
Bennu also contains organic compounds.
Uh-huh.
Including amino acids,
which are the building blocks of proteins,
essential for life as we know it.
Finding these on Bennu suggests that the ingredients
for life might be more common in the solar system
than we previously thought.
(02:48):
That's amazing.
So by studying Bennu,
we're not only learning about our own past,
but we're also getting a glimpse
at the potential for life elsewhere in the universe.
Absolutely.
The discoveries from Bennu have broadened our understanding
of the conditions that might have existed
in the early solar system.
Conditions that could have been favorable
for the emergence of life.
(03:08):
It's a fascinating puzzle,
and we're just starting to put the pieces together.
This is already blowing my mind.
And we're just getting started.
Can you tell us a little more about this daring mission
to collect samples from Bennu?
What did it actually involve?
Okay, so imagine this.
A robotic arm reaching out from a spacecraft,
gently touching the surface of an asteroid
(03:29):
millions of miles away,
and scooping up this precious sample.
Millions of miles away.
Millions.
It took years of planning.
Incredible precision to pull this off.
It sounds like something straight out
of a science fiction movie.
It does.
Were there any unexpected challenges
or surprises along the way?
Oh, absolutely.
One of the biggest surprises came
(03:50):
when they opened up the sample capsule back on Earth.
Not only did they find the expected rock and dust,
but there was this bonus layer of loose material
that had been kicked up during the collection process.
It was like Bennu had given us an extra gift.
A little something extra to study.
An extra gift from an asteroid.
Now I know they found water and organic compounds,
(04:12):
but what else can this cosmic time capsule tell us?
The Bennu sample is like a treasure trove of information.
They found volatile chemicals like ammonia,
which suggests that Bennu formed far away from the sun.
Think about it, maybe out near Neptune.
Wow.
And then it eventually migrated inward.
So Bennu has traveled billions of miles
(04:34):
across the solar system
to end up right in our cosmic backyard.
And we managed to snag a piece of it.
Exactly.
And it gets even more incredible.
They even found pre-solar grains.
Pre-solar grains.
Okay, I'm gonna need you to break that down
for me and our listeners.
What are those?
These tiny grains are older than our sun itself.
Really?
They're like microscopic time capsules
(04:55):
from before our solar system even existed.
Wait, older than the sun?
How is that even possible?
It's mind boggling, isn't it?
These grains formed in the aftermath of previous stars.
Oh wow.
Remnants of ancient stellar explosions
that seeded the interstellar cloud
from which our solar system eventually formed.
They're like little bits of star dust
carrying the legacy of previous generations of stars.
(05:17):
Yeah, it really is amazing.
By studying these pre-solar grains,
scientists can get a glimpse into the conditions
that existed in the universe before our sun was even born.
It's like reading a history book written in star dust.
That's incredible.
It makes you realize that we're all connected
to this vast cosmic history.
That the atoms in our bodies were once part of stars
(05:37):
that lived and died billions of years ago.
Exactly.
And Bennu is helping us understand
how those atoms came together to form the planets,
the water, and ultimately the life we see today.
Okay, so we've talked about water, organic compounds,
pre-solar grains, all incredibly fascinating.
But I wanna go back to those water rich minerals
for a second.
I'm still having trouble wrapping my head around the idea
(05:58):
that the water we drink might've come from asteroids.
Is there really strong evidence to support that, Piri?
It's a hotly debated topic in the scientific community,
but the evidence from Bennu
is certainly adding fuel to the fire.
The types of water rich minerals found on Bennu
are similar to those found in carbonaceous
chondrite meteorites, which are thought to be
(06:20):
some of the most primitive objects in the solar system.
And the isotopic ratios of the water molecules on Bennu
closely match those found in Earth's oceans.
Isotopic ratios, okay.
I'm gonna need you to break that down for me
like I'm five years old.
Okay, imagine water molecules like little fingerprints.
Okay.
Each type of water, whether it's from Earth,
an asteroid, or a comet, has a unique fingerprint
(06:43):
based on the ratio of different isotopes of hydrogen
and oxygen in the water molecules.
So by comparing these fingerprints,
scientists can trace the origins of Earth's water.
Exactly.
And the fact that Bennu's water fingerprint
matches that of Earth's oceans so closely
suggests that asteroids like Bennu
could have been a major source of our planet's water.
Wow.
(07:03):
So it's possible that billions of years ago,
Earth was a dry, barren world, and then bam,
asteroids like Bennu came crashing in,
delivering the water that would eventually
fill our oceans and make life possible.
It's a dramatic scenario, but one that's gaining
more and more support from the scientific community.
Of course, there's still a lot we don't know
(07:25):
about the details of how this all happened,
but Bennu is providing us with some critical clues.
It's like a cosmic puzzle,
and we're slowly piecing together the image.
But I'm also curious about Bennu's journey
through the solar system.
You mentioned that it might have originated
out near Neptune.
How did it end up in our neighborhood?
That's another great question.
Scientists believe that Bennu's parent body,
(07:46):
a much larger asteroid, was shattered
billions of years ago, probably due to a collision
with another object.
This collision sent fragments like Bennu
scattering throughout the solar system,
some of them eventually ending up in orbits
that brought them close to Earth.
So Bennu is like a cosmic wanderer,
a piece of a much larger story that's been unfolding
for billions of years.
(08:07):
It's amazing to think about the journey
it's taken to get here.
And speaking of journeys, the OSIRIS-REx spacecraft,
now renamed OSIRIS-APEX, is on a new mission
to rendezvous with another near-Earth asteroid,
Apophis, in 2029.
Apophis, now that's an asteroid I've heard of.
Wasn't there some concern a while back
that it might pose a threat to Earth?
Yeah, there was a brief period of concern
(08:29):
when initial observations suggested a small possibility
of an impact in 2029.
However, further analysis, more refined observations
have ruled out any chance of a collision
in the foreseeable future.
Phew, that's a relief.
But why send a mission to study Apophis if it's not a threat?
Well, even though Apophis isn't going to hit us,
it's still an incredibly valuable target
(08:51):
for scientific study.
By studying Apophis up close, we can
learn more about its composition, structure,
and how it interacts with the sun's gravity.
This information will not only help us understand
Apophis better, but also improve our knowledge
of asteroids in general, which is
crucial for planetary defense.
So it's not just about scientific curiosity.
It's about protecting Earth from potential asteroid threats
(09:12):
in the future.
Absolutely.
The more we understand about asteroids,
the better prepared we'll be to deal with any potential hazards
they might pose.
OSIRIS APEX will be our eyes and ears on Apophis,
giving us valuable data that will help us refine our models
and improve our ability to predict
the trajectories of these celestial objects.
So we're not just learning about the past with Bennu.
(09:33):
We're also preparing for the future with Apophis.
It's amazing how these missions connect our understanding
of the universe with the practical concerns
of protecting our own planet.
And that's the beauty of space exploration.
It pushes the boundaries of human knowledge,
it inspires innovation, and ultimately helps us
understand our place in the cosmos.
This is mind blowing stuff.
(09:54):
And I'm sure our listeners are just as captivated as I am.
Before we move on, though, I want
to take a moment to reflect on everything we've learned
so far, from Bennu's origins in the early solar system
to its potential role in bringing water and water
to Earth to the ongoing mission to study Apophis.
It's been an incredible journey.
What stands out to you as the most significant takeaway
from all of this?
For me, it's the realization that we're not just observers
(10:16):
of the universe.
We're participants in a grand cosmic story that's
been unfolding for billions of years.
Every atom in our bodies, every drop of water we drink,
every grain of sand on the beach,
it all came from somewhere.
And it all has a story to tell.
Bennu is a reminder of that connection, a tangible piece
of the universe's history that we can hold in our hands
(10:39):
and study in our labs.
You know, it's funny.
We started this deep dive talking about Bennu
as a time capsule from the early solar system.
But it's more than that.
It's a reflection of ourselves, of our place
in the grand scheme of things.
That's a great observation.
We think of space exploration as this outward thing,
distant stars and galaxies.
(10:59):
But it also turns the mirror back to the past.
It turns the mirror back on us, making
us think about our own origins, our connection
to the universe.
It's humbling to think that we're
made of the same stuff as stars.
And the water we drink might have come from asteroids.
It really puts things in perspective.
It does.
It makes you realize that we're not just living on Earth.
(11:20):
We're a part of it.
And we're a part of something much, much larger,
something that's been unfolding for billions of years.
It makes you wonder, what does it all mean?
What's the point of this whole grand cosmic story
that we're just a tiny part of?
That's the question that philosophers and scientists
have been asking for centuries.
And while there might not be a single definitive answer,
(11:41):
I think that search for the answer is what drives us,
what makes us human, that curiosity,
that desire to understand, the need
to make sense of our place in the universe.
Those are the things that propel us forward,
both as individuals and as a species.
It's like we're programmed to explore, to learn,
(12:02):
to push the boundaries of what we know.
And in doing so, we discover not only
the wonders of the universe, but also the wonders
within ourselves.
I think that's a beautiful way to put it.
The more we learn about the universe,
the more we learn about ourselves.
And the more we appreciate this interconnectedness
of everything, from the smallest subatomic particle
to the largest galaxy.
(12:23):
It's awe-inspiring.
It makes you want to keep exploring, to keep learning,
to keep asking questions.
And that's what we should be doing.
The universe is full of mysteries,
and it's up to us to unravel them.
Who knows what incredible discoveries are out there?
I can't wait to find out.
But for now, I think we've reached the end of our deep dive
into Bennu.
Yeah.
It's been an incredible journey.
(12:44):
And I want to thank you for being such a fantastic guide.
The pleasure was all mine.
I always enjoy sharing my passion for the universe.
And I know our listeners are grateful for your insights.
So before we sign off, what's one final thought
you'd like to leave our listeners with?
Keep looking up at the stars.
Keep asking questions.
And never lose your sense of wonder.
The universe is full of amazing things.
(13:05):
And there's always something new to discover.
Beautifully said.

It makes you realize that we're not just living on Earth.
(11:20):
We're a part of it.
And we're a part of something much, much larger,
something that's been unfolding for billions of years.
It makes you wonder, what does it all mean?
What's the point of this whole grand cosmic story
that we're just a tiny part of?
That's the question that philosophers and scientists
have been asking for centuries.
And while there might not be a single definitive answer,
(11:41):
I think that search for the answer is what drives us,
what makes us human, that curiosity,
that desire to understand, the need
to make sense of our place in the universe.
Those are the things that propel us forward,
both as individuals and as a species.
It's like we're programmed to explore, to learn,
(12:02):
to push the boundaries of what we know.
And in doing so, we discover not only
the wonders of the universe, but also the wonders
within ourselves.
I think that's a beautiful way to put it.
The more we learn about the universe,
the more we learn about ourselves.
And the more we appreciate this interconnectedness
of everything, from the smallest subatomic particle
to the largest galaxy.
(12:23):
It's awe-inspiring.
It makes you want to keep exploring, to keep learning,
to keep asking questions.
And that's what we should be doing.
The universe is full of mysteries,
and it's up to us to unravel them.
Who knows what incredible discoveries are out there?
I can't wait to find out.
But for now, I think we've reached the end of our deep dive
into Bennu.
Yeah.
It's been an incredible journey.
(12:44):
And I want to thank you for being such a fantastic guide.
The pleasure was all mine.
I always enjoy sharing my passion for the universe.
And I know our listeners are grateful for your insights.
So before we sign off, what's one final thought
you'd like to leave our listeners with?
Keep looking up at the stars.
Keep asking questions.
And never lose your sense of wonder.
The universe is full of amazing things.
(13:05):
And there's always something new to discover.
Beautifully said.
