Imagine being a student and getting to send something you built into space.
Wow!
That's the incredible opportunity CubeSats are creating.
It really is.
They're these tiny satellites about the size of a loaf of bread.
Yeah!
Making waves in astronomy and opening doors that were once only a dream.
Yeah!
Welcome to Cosmos Centipods Space and Astronomy series.
Yeah.
Today we're diving deep into the world of CubeSats.
Sounds exciting.
Okay, so you've piqued my curiosity.
Right.
What exactly are CubeSats and how do they become so impactful?
Well, CubeSats revolutionize space exploration.
Okay.
By making it more accessible.
Okay.
Imagine a standardized 10 by 10 by 10 centimeter cube.
That's your basic building block.
Each one weighs just a bit over a kilogram and you can combine them like Legos.
Oh, wow!
To create larger, more complex satellites.
Interesting.
This modular design coupled with off-the-shelf components makes them significantly more affordable
to build than traditional satellites.
So it's like a DIY kit for space exploration.
Exactly.
But how much cheaper are you talking?
Give me some numbers.
It's dramatically cheaper.
We're talking about launching a mission for a few hundred thousand dollars instead of
hundreds of millions.
Wow, that's incredible.
Think about it.
Missions that were once only possible for large government agencies are now within reach
of universities, small businesses, and even individual researchers.
That's a game changer for sure.
Yeah.
It's a playing field and allows for more diverse perspectives and research opportunities.
But cost isn't the only advantage.
Right.
What else makes CubeSat so special?
The speed of development is another major factor.
Building and launching a CubeSat can be done in a matter of months, not years, like traditional
missions.
Oh, wow.
This rapid turnaround is perfect for responding to time-sensitive events like supernova explosions
or studying rapidly changing phenomena.
Plus, CubeSats can often hitch a ride on larger rockets as secondary payloads, further reducing
launch costs and simplifying the process.
Okay, so they're cheaper, faster to develop, and can piggyback on other launches.
But are they limited by their size in terms of what they can actually do in space?
Not as much as you might think.
Despite their small size, CubeSats can be equipped with surprisingly sophisticated instruments.
Okay.
Miniaturized cameras, spectrometers, sensors.
Wow.
And capable of performing various tasks.
Yeah.
From imaging celestial objects to collecting data on radiation and magnetic fields.
It's like having a Swiss Army knife in space.
Wow, that's impressive.
So what kind of research are these tiny powerhouses enabling in astronomy?
One area where CubeSats are making a big impact is the study of exoplanets.
Oh, cool.
You see a mission called Asteria, which was about the size of a briefcase, demonstrated
that these little satellites can detect exoplanets.
Wow.
They're using a technique called precision photometry.
It essentially measures the tiny dips in a star's light that occur when a planet passes
in front of it.
Okay.
But detecting those tiny dips in starlight must require incredibly sensitive instruments.
Right.
How can they achieve that level of precision in such a small package?
That's the remarkable thing about CubeSats and the advancements in miniaturization.
Asteria, for instance, used a highly stable telescope, an advanced software, to achieve
the precision needed to detect those subtle changes in starlight.
So we're talking about finding planets orbiting other stars with a satellite the size of a
briefcase.
Exactly.
What other amazing feats are these CubeSats capable of?
Well, their agility makes them ideal for studying transient events, those sudden fleeting phenomena
in the universe.
Think about gamma ray bursts or supernovae.
Got it.
KickSats can be deployed quickly to capture these events in real time.
Something larger, less maneuverable telescopes often struggle with.
It's like having a rapid response team for cosmic events.
So we're talking about cosmic paparazzi, always ready to capture the celestial action
as it unfolds.
Exactly.
And let's not forget our own store, the Sun, dedicated CubeSats like QC, the CubeSat for
solar particles, are helping us understand solar activity and space weather, which can
impact satellites, communication systems, and even power grids here on Earth.
Okay.
Now that's something we should all be paying attention to.
Right.
Space weather can have real world consequences.
So having a fleet of CubeSats monitoring the Sun is definitely a good idea.
Absolutely.
It provides us with valuable data that helps us predict and prepare for potential disruptions.
And the applications go beyond our immediate neighborhood.
Imagine CubeSats mapping distant galaxies studying dark matter and even probing the
cosmic microwave background radiation.
It's mind blowing to think that something so small can contribute so much to our understanding
of something so vast.
It really challenges our perception of what's possible in space exploration.
Are there any particular CubeSat missions that stand out as signing examples of their
capabilities?
Oh, definitely.
There's MARCO, the Mars Cube-1.
This dynamic duo of CubeSats made history by hitching a ride on NASA's InSight mission
to Mars in 2018.
They became the first CubeSats to venture into interplanetary space, relaying crucial
data during InSight's descent and landing on the red planet.
Wait, CubeSats went to Mars?
That's a giant leap for tiny satellites.
What other groundbreaking missions should we know about?
Well, besides Asterio, which we discussed earlier, there's HaloSat.
This mission focused on mapping the hot gas halo surrounding our Milky Way galaxy.
This halo, which extends hundreds of thousands of light years beyond the visible disk of
our galaxy, is thought to hold secrets about how galaxies form and evolve.
So HaloSat is helping us unravel the mysteries of galactic evolution.
That's incredible.
So the missions are out there pushing the boundaries.
There's HUT-U, the CubeSat UV experiment, which studies the atmospheres of exoplanets
to better understand their habitability and capstone, which is testing navigation systems
in a special lunar orbit, paving the way for the Artemis program to return humans to the
moon.
It sounds like CubeSats are playing a crucial role in almost every aspect of space exploration.
They really are.
But their contribution goes beyond individual missions.
They often complement larger missions, filling in data gaps, providing continuous monitoring,
and even acting as test beds for new technologies before they're integrated into larger, more
expensive spacecraft.
So they're like the unsung heroes of space exploration, quietly working behind the scenes
to advance our understanding of the universe.
Exactly.
Imagine swarms of CubeSats acting as distributed observatories, capturing data from multiple
perspectives simultaneously.
Just like having a network of eyes in space giving us a much richer and more complete
picture of what's out there.
That's brilliant.
And because they're relatively inexpensive, they're also great for testing new technologies
without risking costly flagship missions.
You got it.
CubeSats are all about pushing boundaries and expanding the possibilities in space exploration.
But it's not all smooth sailing.
They do face some inherent challenges.
That's right.
There are always challenges.
What are some of the limitations of working with something so small?
Small size, of course, is a factor.
Their limited size restricts the size and complexity of instruments they can carry.
This affects power generation data storage and the overall lifespan of the mission.
So they're limited in terms of how much power they can generate, how much data they can
store, and how long they can operate in space.
Precisely.
And that brings us to the lifespan issue.
OK.
CubeSats typically operate for months or a few years, which makes long-term observations
challenging.
It's like capturing a glimpse of the universe before they fade away.
So they're like the shooting stars of space exploration.
Brilliant, but fleeting.
That's a poetic way to put it.
Another hurdle is communication.
OK.
Smaller antennas and limited bandwidth mean data transmission can be slower compared to
larger satellites.
That makes sense.
Yeah.
And what about space debris?
Right.
If we're launching more and more of these tiny satellites, are we adding to the growing
problem of junk in space?
That's a valid concern.
Yeah.
And CubeSats has definitely raised concerns about space debris and the potential for collisions
with other spacecraft.
It's a challenge the space community is actively working to address.
OK.
So there are some hurdles to overcome, but the potential of these little CubeSats is
undeniable.

You're referring to the issue of space debris.
Yes.
The sustainability of CubeSat missions is crucial.
We need to ensure that these tiny explorers don't become part of the problem.
So what are some of the ways we can mitigate the risk of CubeSats contributing to space
debris?
There are several approaches being explored.
One is designing CubeSats with propulsion systems that allow them to de-orbit safely
at the end of their mission.
So giving them a controlled death dive back to Earth where they'll burn up harmlessly
in the atmosphere.
Exactly.
Another approach is using materials that naturally degrade in space, reducing the lifespan of
debris.
And I imagine there are also ongoing efforts to track and monitor CubeSats more effectively.
Absolutely.
Improved tracking and monitoring systems are essential for avoiding collisions and maintaining
a sustainable space environment.
It's like air traffic control, but for space.
Precisely.
We need to ensure that CubeSats, despite their small size, are operating safely and responsibly.
It's a challenge, but one that we must overcome if we want to fully realize the potential
of CubeSats for space exploration and scientific discovery.
I completely agree.
The future of CubeSats is bright, but it's up to us to ensure that it's also a sustainable

But now it's time to zoom in on some specific CubeSat missions that are pushing the boundaries
of space exploration.
I'm eager to hear about these trailblazing missions.
Let's start with a mission called QTE, CubeSat UV experiment.
QT, I love the name.
What's its mission objective?
QTE is designed to study the atmospheres of exoplanets, those planets orbiting other stars.
It's specifically focused on understanding how these atmospheres escape into space.
Why is atmospheric escape such a crucial area of study?
Well, the rate at which a planet loses its atmosphere can tell us a lot about its potential
to support life as we know it.
If an atmosphere escapes too quickly, it can make a planet inhospitable.
That makes sense.
So how does SUIT, a satellite the size of a cereal box, manage to study something as
complex as atmospheric escape on planets light years away?
It's quite remarkable.
SUIT uses a specialized ultraviolet telescope to observe the light from exoplanets as they
pass in front of their host stars.
By analyzing this light, it can detect the signatures of escaping gases like hydrogen
and helium.
It's like a cosmic detective sniffing out the escaping atmospheres of distant worlds.
That's incredible.
What other missions are out there that showcase the ingenuity of CubeSat technology?
Another fascinating mission is HaloSat, which is focused on studying the vast halo of hot
gas that surrounds our own Milky Way galaxy.
A halo of hot gas surrounding our galaxy?
That sounds intriguing.
Yes, this halo extends hundreds of thousands of light years beyond the visible disk of
our galaxy.
Astronomers believe it holds clues to the formation and evolution of galaxies.
So HaloSat is helping us understand the bigger picture, the grand story of how galaxies like
our own came to be.
But how does it actually study this halo?
HaloSat uses sensitive X-ray detectors to map the distribution and temperature of the
hot gas in the halo.
By studying these properties, astronomers can gain insights into how the halo formed,
how it interacts with the rest of the galaxy, and what role it plays in the galactic ecosystem.
It's amazing to think that a tiny CubeSat can help us unravel the mysteries of something
as vast and complex as a galactic halo.
Indeed.
It speaks to the power of innovation and the potential of CubeSats to contribute to fundamental
astrophysical research.
What other missions out there highlight the versatility and adaptability of CubeSats?
Well, there's Capstone, which is a pathfinder mission for NASA's Artemis program.
Remember, Artemis aims to return humans to the moon, and Capstone is playing a crucial
role in preparing for that ambitious endeavor.
That's right.
Artemis is a landmark mission.
So how is a tiny CubeSat contributing to such a large-scale human spaceflight program?
Capstone is testing a unique lunar orbit called a Near Rectilinear Halo Orbit, or NRHO for
short.
This orbit is special because it's very stable, requires minimal fuel to maintain, and provides
excellent coverage of the lunar South Pole.
Why is the lunar South Pole so important?
That's where NASA plans to land the first woman and next man on the moon.
The South Pole is thought to contain valuable resources like water ice, which could be crucial
for establishing a sustainable human presence on the moon.
So Capstone is essentially scouting out the landing site, ensuring its safety and viability
for future human explorers.
Exactly.
And while it's doing that, it's also collecting valuable scientific data about the lunar environment,
including its gravity field and the interaction of the solar wind with the lunar surface.
It's a testament to the fact that CubeSats can contribute to both human exploration and
scientific discovery.
Indeed.
And speaking of scientific discovery, let's talk about another exciting mission called
Lunar Flashlight.
That sounds intriguing.
What's its objective?
Lunar Flashlight is designed to use lasers to search for water ice in permanently shadowed
craters at the lunar South Pole.
We talked about water ice being a valuable resource on the moon.
How will Lunar Flashlight search for it in these shadowed craters?
It will reflect sunlight into these dark craters and analyze the reflected light using a spectrometer.
The way the light is reflected can tell us about the composition of the surface within
the craters, revealing the presence of water ice.
So it's like shining a flashlight into the dark corners of the moon searching for those
hidden reserves of water ice.
Precisely.
And this information will be crucial for planning future lunar missions and potentially establishing
a long-term human presence on the moon.
Well, I think it's safe to say that CubeSats are exceeding everyone's expectations.
They're proving that size doesn't matter when it comes to making significant contributions
to space exploration.
I couldn't agree more.
They're revolutionizing the field, making it more accessible, more affordable, and more
innovative than ever before.
And this is just the beginning.
As technology continues to advance, we can only imagine the incredible discoveries and
breakthroughs that await us.
CubeSats have opened up a universe of possibilities, and it's an exciting time to be following
