NASA's Next Space Technologies for Exploration Partnerships is a publicly funded initiative that solicits, selects, and partners with private industry, academia, and international organizations to mature technologies and systems for human and robotic exploration beyond low Earth orbit. The program operates as a bridge between early research and flight-ready systems, enabling collaboration among NASA, corporate contractors, university laboratories, and research centers to deliver prototypes, ground demonstrations, and flight demonstrations for missions such as Artemis program, Lunar Gateway, and future crewed missions to Mars.

Overview

NextSTEP is structured as a series of competitive solicitations and cooperative agreements that target mid‑ to late‑technology readiness levels. It connects NASA Johnson Space Center, Marshall Space Flight Center, Ames Research Center, and Glenn Research Center technical leadership with private partners including legacy primes and new space entrants. The program emphasizes public‑private partnerships similar in intent to Commercial Orbital Transportation Services and Commercial Crew Program, but focused on deep space exploration capabilities such as habitation modules, cryogenic propellant systems, and advanced in‑space propulsion. NextSTEP activities intersect with international frameworks like collaborations with European Space Agency, Canadian Space Agency, and bilateral arrangements with agencies such as Japan Aerospace Exploration Agency.

Objectives and Mission Architecture

The primary objectives are to reduce technical risk, lower cost, and accelerate maturation of systems for sustained human presence beyond low Earth orbit. Objectives include developing deep space habitat prototypes, demonstrating closed‑loop life support concepts, maturing in‑space cryogenic propellant management, and testing advanced thermal protection systems for planetary entry. Mission architectures supported by NextSTEP span incremental approaches: near‑term demonstration on commercial platforms, intermediate staging via concepts for the Lunar Gateway, and long‑lead investments for crewed architectures for Mars Base Camp and surface habitation. The program aligns technologies with programmatic needs of Artemis, Commercial Lunar Payload Services, and international exploration roadmaps to ensure interoperability and standards compliance.

Key Technologies and Demonstrations

NextSTEP funds a portfolio of technology areas: inflatable and rigid expandable habitats, environmental control and life support systems (ECLSS), in‑space fuel storage and transfer, additive manufacturing for space, and advanced propulsion components such as solar electric propulsion and nuclear thermal propulsion research intersections. Demonstration projects have included inflatable habitat prototypes akin to concepts developed by industry partners, cryogenic fluid management experiments that address boil‑off and zero‑gravity behavior, and ECLSS testbeds that incorporate bioregenerative and physicochemical processes. These demonstrations leverage test facilities at White Sands Test Facility, acoustic and vibration labs at Stennis Space Center, and flight test opportunities on platforms like International Space Station resupply missions and suborbital carriers.

Partnerships and Industry Engagement

NextSTEP uses Cooperative Agreement Notices and funded partnerships to engage prime contractors, startups, and university consortia. Industry participants have included established firms and emerging companies, collaborating with research institutions such as Massachusetts Institute of Technology, Stanford University, and Purdue University on sensor suites, materials, and systems engineering. The program complements procurement mechanisms used by SpaceX, Northrop Grumman, Boeing, Blue Origin, and niche suppliers by providing targeted funding and technical oversight. International partners and standards organizations such as European Space Agency and International Space Station partners contribute technical insights and may host or fly cooperative demonstrations.

Program History and Milestones

Launched in 2014, the program evolved from earlier strategic technology efforts at NASA and built on lessons from Constellation program technology work and commercial cargo initiatives. Key milestones include initial rounds of NextSTEP habitation awards, the selection of multiple industry partners for study contracts, successful ground‑test milestones for expandable habitat prototypes, and flight demonstrations of cryogenic storage hardware. The program timeline includes coordination with the selection and development of elements for Artemis and the decision points leading to full‑scale habitation module contracts and integrated demonstrations scheduled across the 2020s.

Funding, Management, and Governance

Governance is maintained by program offices within Human Exploration and Operations Mission Directorate with technical stewardship shared among NASA centers. Funding is allocated through annual appropriations to NASA and executed via cooperative agreements and other transaction authorities that afford flexibility compared with traditional Federal Acquisition Regulation contracts. Budget decisions reflect Congressional authorizations and appropriations, program baselines tied to Office of Management and Budget guidance, and cross‑program reprioritizations driven by milestones and agency strategic guidance.

Challenges, Risks, and Future Directions

Technical challenges include scaling cryogenic propellant storage for long‑duration missions, ensuring reliability and redundancy of life support systems, and certifying novel materials and inflatable structures for crewed flight. Programmatic risks involve schedule slips, cost growth, and coordination among multinational partners and commercial contractors. Future directions emphasize integration of NextSTEP outputs into operational missions such as Lunar Gateway modules, expansion of commercial partnerships for lunar surface habitation, and de‑risking technologies needed for Mars human mission architectures. Continued engagement with industry, academia, and international partners aims to transition NextSTEP prototypes from demonstrations to flight‑qualified systems capable of supporting sustained exploration objectives.
