CubeSat Launch Cost: What It Costs to Launch a 1U to 12U CubeSat in 2026

CubeSats are the most affordable way to put hardware into orbit, but "affordable" still means a serious budget. How much a CubeSat launch costs depends on its size, the launch route and the services around it. Most providers do not publish prices. This guide uses the public reference points that do exist, explains how CubeSat launches are priced in practice, and lists the costs that come on top of the launch itself.

CubeSat sizes and mass limits

CubeSats are built from 10 cm units, called U. The CubeSat Design Specification maintained by Cal Poly lists these typical maximum masses:

1U: 2.00 kg
1.5U: 3.00 kg
2U: 4.00 kg
3U: 6.00 kg
6U: 12.00 kg
12U: 24.00 kg

The specification notes that larger masses may be evaluated mission by mission and that acceptable masses depend on the dispenser. NASA's small spacecraft report adds that dispensers now offer up to 12U and more, and several providers offer 12U and 16U dispensers.

The public reference price

SpaceX publishes its rideshare price: $350,000 for 50 kg to sun-synchronous orbit, plus $7,000 for each additional kilogram. The smallest standard slot is a quarter plate with 50 kg included. SpaceX's rideshare guide describes CubeSat payloads as an integrated CubeSat dispenser assembly with a single mechanical interface to the rocket, containing one or more dispensers and the CubeSats inside them.

That means a single CubeSat is rarely booked directly. Even a 24 kg 12U CubeSat uses less than half of the 50 kg included in the minimum slot.

What this means per CubeSat

If one CubeSat booked a whole quarter plate alone at list price, the cost per kilogram at its maximum mass would be:

1U (2 kg): $350,000, which is $175,000 per kg
3U (6 kg): $350,000, about $58,300 per kg
6U (12 kg): $350,000, about $29,200 per kg
12U (24 kg): $350,000, about $14,600 per kg

These are our own calculations from the published list price. They show why CubeSats almost always share a slot. A launch integrator books the capacity, fills a dispenser assembly with several CubeSats from different customers and splits the cost. The price each customer pays is set by the integrator and is usually quoted on request.

Ways to launch a CubeSat

Through an integrator on a rideshare: the most common route. NASA explains that integrators perform analyses and physical integration and may provide the dispenser.
On a small launcher: rockets like Electron carry CubeSats on dedicated or shared missions, see launch providers compared.
From the ISS: CubeSats travel to the station as cargo and are deployed from there. NASA notes that the Nanoracks CubeSat Deployer releases them at 51.6° inclination into a 400 to 420 km orbit, one to three months after berthing. The cover image shows a CubeSat being ejected from the Japanese deployer.

Low-cost programs for universities and nonprofits

NASA CubeSat Launch Initiative (CSLI): gives selected U.S. educational institutions and nonprofit organizations what NASA calls a low-cost pathway to space. NASA says its announcement of partnership opportunity is typically released each August, with proposals due in November, and that CSLI has launched over 150 CubeSats.
ESA Fly Your Satellite: according to NASA's report, it provides launch opportunities to university CubeSat teams from ESA Member States, Canada and Slovenia.

Costs on top of the launch

Dispenser or integration fee, often included in the integrator's price
Testing: vibration and thermal vacuum; SpaceX's guide defines test levels for fully containerized CubeSat units
Licensing: radio frequency licensing is needed for every satellite, see spectrum licensing
Transport to the integrator or launch site
Insurance, if required
Ground station access for operations, see Ground Station as a Service
Rebooking fees if the CubeSat is late; SpaceX charges 5 to 10% of the money paid for rebooking

How to get a real quote

Fix the size, mass and target orbit.
Decide on your readiness date and how flexible it is.
Ask integrators and launch providers for quotes that include the dispenser and integration services.
Check whether you qualify for CSLI or Fly Your Satellite.

You can send one request to several providers through Carrier Space's cargo transport request.

Frequently asked questions

How much does it cost to launch a CubeSat?

There is no single public price per CubeSat. SpaceX lists $350,000 for a minimum rideshare slot with 50 kg to SSO, which integrators usually share among several CubeSats. Your price depends on the integrator's quote.

How much does a 1U CubeSat launch cost?

Integrators set prices for individual CubeSats on request. Booked alone at SpaceX's list price, a 1U would pay the full $350,000 minimum.

Can I launch a CubeSat for free?

NASA describes CSLI as a low-cost pathway for selected U.S. educational and nonprofit teams. ESA's Fly Your Satellite offers launch opportunities to university teams in ESA Member States, Canada and Slovenia.

How heavy can a 6U CubeSat be?

The CubeSat Design Specification lists 12 kg as the typical maximum for 6U, with exceptions possible depending on the dispenser.
