About this program
NASA awards grants under the Exploration program (CFDA 43.003) to develop systems and capabilities for human exploration of the Moon and Mars, with the most recent award made on July 16, 2026. The program funds development of the Orion crew exploration vehicle, Space Launch System (SLS) rocket, Exploration Ground Systems (EGS), lunar orbit and surface infrastructure including the Gateway lunar station, Human Landing System (HLS), extravehicular activity systems, and habitation technologies for long-duration lunar and deep-space missions. Awards also support advanced cislunar navigation, surface mobility systems, and preliminary concept studies for eventual Mars transit habitats.
Activity has slowed significantly in recent years. The program issued 593 total awards since 2007, but the award cadence has dropped sharply—from 16 awards in both 2022 and 2023 to just 7 in 2024, 4 in 2025, and 2 through mid-2026. No recent grant opportunities are currently posted in the source material; the most recent opportunity documents date to late 2023 and earlier.
The portfolio comprises predominantly Project Grants (77 percent, 454 awards) with a substantial Cooperative Agreement share (23 percent, 139 awards). Combined federal dollars obligated total $884.8 million. NASA Shared Services Center dominates by both award count and funding magnitude, accounting for 428 awards and $510 million in federal obligations. NASA Goddard Space Flight Center ranks second by funding with just 3 awards but $256.1 million obligated, reflecting large infrastructure or research center awards. NASA headquarters accounts for 156 awards and $112 million; smaller contributions come from Stennis Space Center ($492 thousand across 3 awards) and Ames Research Center ($5.9 million, 1 award).
Recent awards illustrate the program's breadth. A $40,700 project grant (July 2026) funds design and construction of a Langmuir probe to characterize the polar lunar plasma environment. A $4.9 million Cooperative Agreement (August 2023) supports the Center for Lunar Environment and Volatile Exploration Research (CLEVER). Large infrastructure awards include a $76.1 million Cooperative Agreement to Goddard's Center for Research and Exploration in Space Science and Technology (October 2024) and a $54.9 million award for Human Systems Integration collaborative research (January 2022). Technology development spans additive manufacturing, lunar landing trajectory optimization, battery materials for low-temperature applications, and magnetic joint actuators for space applications.
The award profile reveals maturation of earlier development phases: mega-awards to established research centers have grown while new solicitations appear infrequent. The dramatic decline in annual award count suggests the program may be in a consolidation phase or awaiting new budget-cycle opportunities.
Objective and description
- Objective
The Exploration Systems Development Mission Directorate (ESDMD) defines and manages systems development for programs critical to the NASA's Artemis campaign and planning for NASA's Moon to Mars exploration approach in an integrated manner. ESDMD mana
- Description
Exploration provides for the development of systems and capabilities needed for human exploration of the Moon and Mars. ESDMD is building a space transportation system comprised of the Orion deep crew exploration vehicle, Space Launch System (SLS) rocket, and Exploration Ground Systems (EGS). These capabilities enable the Agency's Artemis missions, extending human presence into the solar system by transporting crews to lunar orbit and safely back to Earth in preparation for future missions to Mars. Advanced Cislunar and Surface Capabilities (ACSC), Gateway, Human Landing System (HLS), and Exploration Extravehicular Activity (xEVA) and Human Surface Mobility Program (EHP) will create the exploration infrastructure in lunar orbit and on the lunar surface that astronauts will utilize during Artemis missions and that will inform future missions to Mars. The Exploration Capabilities Program develops habitation systems and technologies to enable long missions on the lunar surface and in deep space and to address high priority technology gaps. MCD will begin conducting preliminary concept studies for future systems, including an eventual transit habitat that will provide living quarters and other basic life support functions for future human mission to Mars.
Eligibility
- Applicant eligibility
Categories of organizations that may be eligible for NASA grants and cooperative agreements include: • Institutions of Higher Education (IHE) - A two- or four-year university or college (including U.S. community colleges), public or private, accredited to confer degrees beyond that of the K-12 grade levels. 29 • Educational Institutions - Non-higher-education entities, such as K-12 education groups or institutions of informal education, are classified as Educational Institutions.2 • Non-profit Organization - An organization that: o Is operated primarily for scientific, engineering, educational, research, or similar purposes in the public interest; o Is not organized primarily for profit; o Uses net proceeds to maintain, improve, or expand the organization's operations; and o Is not an IHE. Non-profit organizations generally exclude (i) colleges and universities; (ii) hospitals; and (iii) state, local, and Federally recognized Indian tribal governments. • For-profit Entity - An organization of any size that is organized primarily for profit. • Federally Funded Research and Development Center (FFRDC) - FFRDCs are under a broad charter by a Government agency for performing, analyzing, or conducting research for the United States Government. NASA sponsors JPL as the Agency's sole FFRDC, and JPL is not an eligible applicant to receive a NASA-funded grant or cooperative agreement as a recipient or subrecipient3 . However, FFRDCs sponsored by agencies other than NASA may be eligible to receive a NASA-funded award as a recipient or subrecipient. • Non-U.S. Organizations - Organizations outside the U.S. that meet the definitions of foreign organization or foreign public entity in 2 CFR § 200.1. Non-U.S. organizations generally propose for opportunities on a no-exchange-of-funds basis in accordance with NASA policy. NOFOs may be issued jointly with a non-U.S. organization (e.g., those concerning guest observing programs for jointly sponsored space science programs) that will contain additional special guidelines for non-U.S. participants. • State, Local, or Federally-Recognized Tribal Government Agency - o State Government means any state of the United States, the District of Columbia, the Commonwealth of Puerto Rico, any territory or possession of the United States, and any agency or instrumentality of a State exclusive of its local governments
