The Boost! programme
With Boost! ESA is offering a lean and flexible partnership framework to commercially oriented entrepreneurs and their consortia to help turning new and innovative space transportation service concepts into commercial reality.
With the objective to promote and support qualifying service projects targeting European and global markets, the Boost! programme is looking for European companies developing commercial space transportation services under their own initiative and responsibility, and targeting access to space, in-orbit transportation and return-from-space capabilities.
By providing support at service level, co-funding, know-how and expertise, access to test facilities, etc., Boost! is uniquely positioned to make a difference for space transportation service developers in succeeding to develop and deploy new competitive and innovative services on the market. This is your chance to benefit from Boost!

Purpose of this Channel
The purpose of this Channel is to facilitate the implementation of the first step of the procurement process as defined in the Call For Proposals published on esa-star publication under CfP/4-40003 in the "ESA tender Actions".
Its purpose is further to guide interested companies to submit an Outline Service Proposal to ESA, initiating the first step of the tendering process that will lead to the decision on the eligibility of the service project for Boost! support.
An overview of the complete tendering process is presented for information below.
Please also refer to the Frequently Asked Questions-page on the Boost! website.
Tendering Process
The tendering process follows a two step- approach:

First Step: Submission of an Outline Service Proposal using the submission form here in OSIP
- Enter your Outline Service Proposal (also called "idea" here in OSIP) via the idea submission form;
- Each Outline Service Proposal will be assessed by ESA experts against the entry requirements and assessment criteria found at the bottom of this page;
- If the assessment is positive then you will be invited to submit a Full Service Proposal.
Please take note the Special Conditions applying to the submission as listed below. An Outline Service Proposal may be submitted at any time, but ESA will evaluate proposals in batches following key submission dates.
Second Step: Submission of Full Service Proposal in esa-star Tendering
- Write and submit a Full Service Proposal through esa-star;
- ESA will evaluate your proposal against evaluation criteria stated in the data pack from the Call For Proposals published on esa-star publication under CfP/4-40003 in the "ESA tender Actions";
- Successful proposals will be invited to a negotiation meeting and possibly lead to a co-funding contract award.
Scope of eligible service projects
Boost! is a commercialisation programme of ESA's Space Transportation Directorate, and thus the programme is targeting space transportation service projects for its support. We are looking for commercially operating private ‘for-profit’ prime companies, potentially involving consortium partners, and developing services in one of the two following categories:
Category 1: End-to-end commercial space transportation services:
Any space transportation service that carries payloads for paying customers. Such services may include one or a combination of the following:
- Access to Space Services - launch services development and pre-commercial activities, industrialisation, consolidation and service capability extension
- In-Orbit Transport Services - orbital transfer services including ‘last-mile’ in-orbit precision deployment and phasing; space transportations aspects for in-orbit servicing systems development and demonstration
- Return from Space Services - return-to-earth service capabilities including re-entry platform development, demonstration and space segment reuse
Service providers shall demonstrate that space transportation services are delivered to end customers in the sense that service customers shall not need to procure any additional essential service elements to obtain the full service.
Category 2: Stand-alone commercial ground-based and in-flight services:
Any novel stand-alone ground-based and in-flight services provided to commercial space transportation service provider(s) and/or spaceport operator(s). Such services may include one or a combination of the following:
- Launch range services (e.g. combined operations and mission support; range safety and security) Establishment of new services required for re-usability (e.g. re-entry, recovery and reuse operations and infrastructure)
- Establishment of new services required for re-usability (e.g. re-entry, recovery and reuse operations and infrastructure)
- Establishment of new propulsion test service proposals for development and exploitation
- In-flight support services, including data services (e.g. launch vehicle telemetry, data links to in-orbit transport missions), space safety (e.g. space debris collision avoidance)
- Software based services (e.g. in support of complex missions).
Note: Service providers shall demonstrate that the stand-alone commercial ground-based and in-flight services are conceived to serve multiple space transportation service providers or spaceport operators as end customers in a non-exclusive setting.
Entry Requirements
Service projects submitted in response to the Boost! Call for Proposals shall be compliant with the following entry requirements in order to become eligible for Boost! co-funding and support:
R1: The proposed space transportation service fall within one of the two categories:
- Category 1: to space; in space; from space, or any combination of it.
- Category 2: stand-alone ground-based and/or in-flight service to a space transportation service
R2: The space transportation service is targeting end customers in the sense that service customers does not need to procure any additional essential service elements to obtain the full service (e.g. access to facilities, transport or logistics, etc.).
R3: Preparatory activities of providing the service have completed, at minimum, the feasibility phase at service level (completion of Phase A equivalent), and preliminary definition of relevant systems have started.
R4: The service shall target a commercially viable and sustainable business opportunity, oriented toward private sector customers, without relying on guaranteed European institutional demand in the operational phase and with a long-term vision of service provision.
R5: The new space transportation service is based on a privately-led initiative, with the Economic Operator taking responsibility for the full service development, deployment, and funding scheme, and throughout the whole value chain.
R6: Fundraising has completed Series A round or equivalent. It is expected that the funding secured by the time of Outline Service Proposal submission covers at least in the order of 10% of the anticipated service deployment cost.
Co-funding options and conditions
ESA will co-fund eligible activities up to the maximum percentage indicated in the table below and the remainder has to be funded by the Tenderer and its Sub Contractors.
