The economics of getting to orbit.
A decade ago, launching a shoebox-sized satellite could cost as much as the satellite itself. Rideshare changed the math. By selling standardized slots on a single rocket to dozens of customers at once, providers drove the price per kilogram down by an order of magnitude — and made the modern CubeSat business model possible.
Two routes to orbit, two cost structures
Rideshare means sharing a rocket with many other payloads, which spreads the fixed cost of a launch across everyone aboard. SpaceX's Transporter, Bandwagon and Twilight missions are the dominant example, flying out of Vandenberg into Sun-synchronous orbit. The trade-off is control: you fly on the provider's schedule, to the provider's orbit, in a standardized deployer. Rideshare typically costs 50–80% less per kilogram than buying a dedicated launch.
A dedicated launch — a whole small rocket to yourself — buys precise orbit selection, timing and deployment control, at a much higher unit cost. Most CubeSat operators take rideshare and accept the standard drop-off, then use onboard propulsion (see section 01) to fine-tune their orbit afterward.
From manifest to orbit
Book a slot
Operators reserve mass on an upcoming Transporter or similar mission, often 12–18 months out, with a published per-kilogram rate and a standard deployer interface (e.g. a CubeSat dispenser).
Integrate & test
The satellite is built to the deployer's mechanical and safety envelope, vibration-tested, and delivered to the integrator weeks before launch.
Stack & launch
Dozens to 100+ payloads are stacked on a single upper stage. Transporter-16 (March 2026) carried 119 payloads on one flight.
Deploy & commission
The dispenser springs each CubeSat free at the target orbit. The operator then detumbles, powers up, and — if equipped — begins propulsive orbit-raising or phasing.
What a launch line actually includes
The headline per-kilogram figure is only part of a mission budget. Operators also account for the deployer fee, integration and testing labor, insurance, licensing and regulatory filings, and any orbital-tug or last-mile transfer service if the standard drop-off orbit isn't close enough to the target. The launch's low cost is precisely what makes spending on a smarter bus — better propulsion, better comms — worthwhile: when getting to orbit is cheap, the differentiator moves to what the satellite can do once it's there.
