Communications Services Project


NASA’s Communications Services Project, known as CSP, is pioneering a new era of space communications by partnering with industry to provide commercial space relay communications services for NASA missions near Earth. CSP’s goal is to validate and deliver these commercial communication services to the Near Space Network by 2030. To meet this goal, CSP provided $278.5 million in funding to six domestic partners to develop and demonstrate space relay communication capabilities.

CSP aims to deliver innovative capabilities to meet NASA mission needs, while simultaneously supporting the growing commercial space communications market in the United States. CSP intends for future commercial space relay communication services to also support other government agencies and commercial space flight companies, further bolstering the domestic space industry.

Capability Development and Demos

CSP’s Capability Development and Demonstration (CDD) sub-project is responsible for ensuring commercial space relay capabilities will be available to support NASA missions and ready for validation in 2028. The CDD sub-project also conducts insight into industry activities, primarily through partnership agreements such as the Funded Space Act Agreements (FSAAs) CSP established with six industry partners.

Mission Support

CSP’s Mission Support (MS) sub-project supports NASA missions as they prepare to make the transition to commercial space relay communication services. The MS sub-project leads CSP’s Commercial Services User Group and conducts simulations to help mission better understand the benefits and impacts of transitioning to commercial communication services. In addition, the MS sub-project facilitates demonstrations between early-adopter NASA missions and commercial service providers.

Service Infusion

CSP is developing a set of service requirements that commercial providers must meet before they can provide operational services to NASA missions. The CSP Service Infusion (SI) sub-project is responsible for developing, and coordinating, these service requirements with key stakeholders including the mission community, the Near Space Network, and NASA’s mission directorate leadership. The CSP SI sub-project is also responsible for validating commercial services and transitioning these services to the NSN for operational use.

Near Earth Operations Testbed

CSP’s Near Earth Operations Testbed (NEO-T) sub-project develops advanced hardware-in-the-loop emulation capabilities that allow NASA missions interact with commercial space relay communication services from the comfort of the laboratory. NEO-T will allow direct connections between mission hardware and actual commercial provider systems, and supports missions from planning through system integration phases, and beyond.
