Kickstarter · Build-first, launch-as-stretch

Help us build a smarter small satellite.

CubeSat33 is a 3U CubeSat — about the size of a loaf of bread — built around two systems that make every minute in orbit productive: dual-mode green propulsion and high-speed laser communications with active beam steering. We're raising the funds to build it, test it, and put your name on it.

The mission

What we're building, and why it matters

CubeSat33 is built around two core systems that work together to maximize mission success — so every minute in orbit becomes productive, with far more time observing and much faster data delivery.

Core system 01

Dual-mode green propulsion

A single green propellant that switches between fast chemical thrust and efficient electrospray mode — one tank, two jobs: rapid maneuvers when you need them, and years of fuel-sipping station-keeping for a long, productive mission.

Core system 02

High-speed laser comms

An optical downlink with active beam steering that rapidly delivers large amounts of data during every available pass — so valuable observations come home fast instead of sitting unused onboard for hours.

Looking ahead

A future relay concept

Down the road, the same bus could hand data to a satellite communications system such as Starlink (or a similar network) for near-real-time delivery — a future concept we explore on the project page. No partnership exists today.

Where your money goes

Funded in phases, so the base stays achievable

The base goal builds and bench-tests a real satellite. Stretch goals, funded by pledges beyond the base, carry it to qualification and orbit.

$150,000 · Base — Build & bench-test

Engineering model (flight computer, power, attitude control), the dual-mode propulsion testbed, the laser-comms downlink, a ground station, and the core team. Outcome: a working CubeSat33 bus proving both core systems on the bench.

$320,000 · Stretch — Flight hardware

Procure and assemble all flight subsystems, including the electric-propulsion module.

$480,000 · Stretch — Qualification

Full environmental testing (vibration + thermal-vacuum), flight software, and spectrum licensing — a launch-ready satellite.

$700,000 · Stretch — Launch & operate

A rideshare launch slot, deployer integration, insurance, 12 months of operations, and an open-data portal for the laser-comms downlinks.

Timeline

From funding to flight

Month 0 — Funding closes

Lock the design; order long-lead avionics.

Months 1–4 — Build

Assemble the engineering model; integrate the dual-mode propulsion testbed and laser-comms downlink.

Months 4–7 — Bench-test & first rewards

Test the full stack; demonstrate both core systems on the ground; ship pins, patches and tees to backers.

Months 7–18 — Qualify & launch (stretch-dependent)

Flight hardware, environmental qualification, rideshare integration, orbit and operations.

Honest about it

Risks & challenges

The future relay concept would need an operator's cooperation. The relay idea is a future concept, not part of the core mission. Consumer terminals today talk only to their own constellation, not to a third-party CubeSat, so that vision depends on a satellite operator (such as Starlink, or a similar network) choosing to enable it — and no such agreement exists today. Importantly, nothing in this campaign depends on it: the funded mission is the dual-mode propulsion and laser-comms bus, demonstrated on the bench.
Launch is a stretch, not a guarantee. Reaching orbit requires hitting the launch stretch goal and securing a rideshare slot. Flight-dependent rewards are clearly marked, and we won't promise orbit we haven't funded.
Hardware is hard. Schedules slip and parts get delayed — that's why there's a 12% contingency and a phased plan, and why we lean on commercial off-the-shelf subsystems from established CubeSat suppliers.
FAQ

Common questions

Is this a real satellite or just a website?

Real hardware. The site explains the engineering; this campaign funds building it.

What if you don't hit the base goal?

Kickstarter is all-or-nothing. If we don't reach $150,000, no one is charged and the project doesn't proceed.

What if you raise more than the base but not enough to launch?

The base builds and bench-tests CubeSat33. Additional funds unlock flight hardware, qualification, and launch via the stretch goals. Flight-dependent rewards are fulfilled only if we reach orbit.

Why mention Starlink at all?

Only in the context of the future relay concept, and only as the clearest example of a satellite communications system that already operates every link in the chain. The concept fits any comparable network, and we say "Starlink or a similar system" throughout. CubeSat33 is not affiliated with, endorsed by, or in partnership with Starlink, SpaceX, or any operator — no such relationship exists.
