You might be surprised what you can send into space with a few centimeters of volume and a well-thought-out plan.

PocketQubes — those tiny, cube-shaped satellites that measure just 5cm per side — are rewriting the rules of what’s possible in orbit. When we built and launched HADES‑ICM at Interstellar Communication Holdings Inc., our goal wasn’t just to prove that something so small could survive space. It was to demonstrate that it could carry meaning. Utility. Even imagination.

That’s the thing about payloads: they don’t have to be huge. They just have to be intentional.

And PocketQubes, in their compact simplicity, are turning into platforms for everything from scientific experiments to artistic expression to new communication tools.

Let’s take a look at what’s possible — and what’s already happening.

1. Research: Science in Miniature

PocketQubes are ideal for scientific exploration, particularly in low-Earth orbit (LEO). Their size limits the scale of payloads — but not their value.

You’ll find:

Environmental sensors (temperature, pressure, radiation)

Biological experiments (like how microbes react to microgravity)

Material tests (how composites or coatings handle cosmic exposure)

Magnetometer readings for studying the Earth's magnetic field

One of the more fascinating recent missions involved a PocketQube carrying a micro ion detector to monitor charged particles in the upper atmosphere. With a short mission life, it gathered useful data — and returned insight far beyond its weight class.

HADES‑ICM itself includes a suite of telemetry tools designed to track onboard health, but also provide insight into passive orbital behaviors — like thermal cycling and battery degradation.

PocketQubes allow universities and independent researchers to run real science on real satellites, without waiting years or spending millions.

2. Art: Storytelling from Orbit

Yes, art belongs in space too.

And no, we don’t mean murals on space station walls. We mean payloads that are expressive, reflective — and sometimes downright poetic.

Some PocketQube missions have:

Encoded poems in Morse code broadcast over FM frequencies

Carried voice recordings that loop during orbital passes

Transmitted visual pixel-art patterns using slow-scan television (SSTV)

Included tiny plaques with artwork etched onto metal, exposed to space

When you realize that anyone with a modest SDR setup can receive these transmissions, the project shifts from being “just technical” to something much broader.

Suddenly, someone in a rural village can hear a poem beamed down from space.

That’s… kind of incredible.

At Interstellar Communication Holdings Inc., we’ve always believed in space as a shared canvas, and we’ve had the privilege of collaborating with educators and artists to explore new ways to use orbit as a form of expression.

3. Communications: Making Contact Count

Communications is where PocketQubes arguably shine brightest.

They can act as:

Amateur radio repeaters

Beacon transmitters for educational outreach

Telemetry platforms for global ground station collaboration

Data relays for remote sensing networks

Because they’re affordable and modular, they allow organizations — even individuals — to experiment with new protocols, test antennas, and explore mesh communication in space.

Take HADES‑ICM again. It broadcasts telemetry packets that are publicly decodable. Anyone can track its orbit, collect data, and even submit reception logs. That model creates a collaborative environment, not just a one-way broadcast.

Some newer PocketQube concepts are now testing delay-tolerant networks — relaying packets between satellites in low-Earth orbit before beaming them down. That has huge implications for disaster recovery zones, maritime communications, or rural education support.

So while the form factor is tiny, the possibilities for interaction are huge.

Why It Matters

Payload versatility isn’t just a feature of PocketQubes. It’s the whole point.

In a world where getting to space used to mean fighting for access, these little cubes are giving that access back. To students. To artists. To ham radio clubs. To curious minds.

And as a company based in the United States, we're proud that Interstellar Communication Holdings Inc. has contributed to this ecosystem — not just by launching satellites, but by opening doors.

That’s also part of why we’re honored to be a nominee for the 2025 Go Global Awards, hosted by the International Trade Council this November in London. It’s more than an event. It’s a convergence — a place where ideas from every sector and country cross-pollinate, and where small players can have big conversations.

PocketQubes, in a way, are the same: tiny things that create outsized connection.

Final Thought

Science. Art. Communication. Three very different domains — all thriving inside a box the size of a tangerine.

That’s the magic of PocketQubes. They remind us that impact isn’t about volume. It’s about intention, access, and the will to try something unusual.
