Small satellites, big leverage on access to space.
CubeSats have gone from university experiments to a serious platform for science, Earth observation and connectivity. This is a working technical resource on the four systems that decide whether a mission succeeds — how they move, how they launch, how much useful payload they carry, and how they get data home — plus the CubeSat33 bus itself, built around dual-mode green propulsion and high-speed laser communications with active beam steering.
What this site covers
Each section is written for engineers and industry readers: real specifications, current pricing, and the trade-offs that actually drive mission design today.
Moving a satellite the size of a loaf of bread
Electric propulsion — gridded ion, FEEP and electrospray thrusters — now fits in a single CubeSat unit. We compare flight-proven systems and the 2026 dual-mode breakthrough from MIT.
02 · LaunchesThe economics of getting to orbit
Rideshare collapsed launch cost by an order of magnitude. We break down SpaceX Transporter pricing, deployment cadence and what a CubeSat operator actually budgets.
03 · Payload EfficiencyUseful mass, power and volume per unit
The real figure of merit isn't size — it's how much science or service you extract per kilogram, watt and dollar. How miniaturization is pushing that ratio up.
04 · Earth-to-Orbit CommsThe downlink bottleneck and the LEO blackout
A LEO satellite sees a given ground station for only minutes per orbit. We explain store-and-forward, the coverage-gap problem, and where inter-satellite links change the picture.
Meet the CubeSat33 bus
Two core systems, engineered to make every minute in orbit productive.
Dual-mode green propulsion
One green, non-toxic propellant that switches between fast chemical thrust for agile maneuvers and ultra-efficient electrospray for long-duration station-keeping. Agility and endurance from one compact system.
Core system 02Laser comms + active beam steering
An optical downlink that moves far more data than radio, with active beam steering that holds the link as the satellite races overhead — emptying the onboard recorder fast on every available pass.
