Launch Service Agreement (LSA) Explained: What Is in a Satellite Launch Contract?

A launch service agreement, usually shortened to LSA, is the contract between a satellite operator and a launch provider. It turns a reserved slot into a binding commitment and defines who pays what, when the launch happens, what happens if something is late, and who carries which risks. This guide explains the typical building blocks of an LSA, using public sources such as SpaceX's Rideshare Payload User's Guide and the U.S. FAA regulations for commercial launches. It is general information, not legal advice. Every contract should be reviewed by a lawyer with launch experience.

The documents around an LSA

An LSA rarely stands alone. In SpaceX's rideshare process, several documents work together:

The agreement itself: commercial and legal terms.
Statement of work: deliverables and due dates for both sides. SpaceX links its deliverables to Table 1 of the customer's statement of work.
Interface Control Document: the mission-specific technical agreement, see ICD explained.
User's guide: the general technical rules for all customers.

When the contract is signed, SpaceX provides kickoff materials, and each customer gets a single mission manager as technical point of contact until launch.

Key clauses in a launch service agreement

1. Scope of services

What exactly is included. For SpaceX rideshare, the standard service covers a slot on a plate with a defined included mass, standard interfaces and processing in an ISO Class 8 payload processing facility. Other items are optional and cost extra, for example non-standard mechanical adapters, additional deploy signals, payload fueling, electrical ground support connections on the rocket and telemetry monitoring during the countdown. A clear scope prevents surprises later.

2. Price and payment schedule

The total price and when it is due. The contract defines how much is paid at signature and at later milestones. For a pricing reference, SpaceX publishes $350,000 for 50 kg to SSO plus $7,000 per additional kg, see How much does it cost to launch a satellite?.

3. Launch period and schedule

The contract should state how the launch date is defined and how it can change. The schedule of deliverables is defined in the statement of work. In SpaceX's typical rideshare schedule, the first mission analysis inputs are due about eight months before launch.

4. Delays and rebooking

Probably the most important clause for small satellite operators. Who may delay, by how much, and at what cost? SpaceX states on its rideshare page that if a payload is delayed, 100% of the money paid can be applied toward rebooking on a future mission, subject to a 5 to 10% rebooking fee. Check how a contract treats delays caused by the launch provider as well, and whether you can terminate if the launch slips for too long.

5. Termination

Under which conditions either party can end the contract and what is refunded. An example from SpaceX's guide: if SpaceX reasonably determines that a required export license cannot be obtained within a reasonable time, it reserves the right to rebook the customer with rebooking fees, or to terminate the agreement and return all amounts paid without interest and with no further liability.

6. Liability and the cross-waiver

Launches involve several companies whose hardware sits on the same rocket. U.S. law handles this with a reciprocal waiver of claims. Under 14 CFR 440.17, the licensee, its contractors and subcontractors, each customer and their contractors must enter into an agreement in which each party waives claims against the others and accepts responsibility for its own property damage and for injuries to its own employees, regardless of fault. SpaceX provides a cross-waiver template that customers sign to acknowledge these flow-down terms.

7. Insurance

Two kinds of insurance matter. Third-party liability insurance covers damage to people and property outside the mission. Under 14 CFR 440.9, the FAA sets the required amount for each licensed launch, and the policy must protect, among others, the licensee, its customers and contractors, and the United States as additional insureds. SpaceX asks customers to name additional parties for its third-party liability policy and to provide their payload insurer details and subrogation waivers. Insurance for the satellite itself is usually the customer's own decision. See satellite launch insurance and liability.

8. Licensing responsibilities

The launch provider holds the launch license, but the satellite operator remains responsible for its own approvals. NASA's small spacecraft report lists radio frequency licensing, remote sensing licensing and laser approval, and notes that launch providers require proof of licensing before integration. SpaceX also uses an FAA payload review template covering owner and operator information, mission description, hazardous materials, licensing and orbits. See spectrum licensing.

9. Export and import control

For U.S. launches, SpaceX's guide states that providing items, information and services to any foreign person is subject to U.S. export control laws, including ITAR, administered by the Department of State, and EAR, administered by the Department of Commerce. The customer must comply with export and import control laws for its payload, ground equipment and any propellant, including clearance by U.S. Customs and Border Protection. Non-U.S. customers may need a Technical Assistance Agreement, and SpaceX provides a TAA questionnaire for this.

10. Debris and end-of-life obligations

Contracts increasingly pass on space sustainability rules. SpaceX expects all rideshare payloads to follow the FCC rule to dispose of spacecraft as soon as practicable and no later than five years after the mission ends, and to register all deployed objects with the 18th Space Defense Squadron and SpaceX Space Traffic Coordination at least two months before launch.

11. Post-separation responsibilities

Where the provider's job ends. SpaceX provides a best-estimate separation state vector shortly after separation. After that, tracking and contacting the satellite is the customer's responsibility.

Checklist before signing an LSA

Is the scope complete, including adapters, dispensers and any optional services you need?
Does the payment schedule match your funding milestones?
What are the rebooking fees, and what happens if the provider delays?
Can your team meet the deliverable schedule in the statement of work?
Have you reviewed the cross-waiver and insurance requirements with your insurer?
Are your licenses and export approvals on track?
Do you understand your obligations for debris mitigation and object registration?

Frequently asked questions

What is a launch service agreement?

The contract between a satellite operator and a launch provider. It defines scope, price, payment schedule, launch period, delay rules, liability, insurance and compliance duties.

What is a cross-waiver in a launch contract?

An agreement in which all parties involved in a launch waive claims against each other and each carries its own losses. For FAA-licensed U.S. launches, it is required by 14 CFR 440.17.

What happens if my satellite is not ready on time?

It depends on the contract. SpaceX allows customers to apply all payments to a future rideshare mission, subject to a 5 to 10% rebooking fee.

Who needs to insure what?

The launch licensee carries third-party liability insurance in the amount set by the FAA. Insurance for the satellite itself is usually arranged by the satellite owner.

Do I need an LSA if I book through a broker?

You sign a contract with the broker or integrator, who in turn has a contract with the launch provider. The same topics apply, so ask how the provider's terms are passed on to you.
