The 7 Most Critical Projects and Breakthroughs at GRC Today
NASA Glenn Research Center is currently spearheading several high-priority projects that are vital to the Artemis lunar missions and the future of sustainable aviation. These initiatives showcase the center’s unique expertise in extreme environment testing and advanced propulsion systems.
1. Leading the Fission Surface Power Development
GRC has been selected to lead the development of nuclear power systems for lunar missions, a project known as Fission Surface Power (FSP). This is perhaps the most crucial long-term project for sustained human presence beyond Earth. A reliable, high-power energy source is essential for operating habitats, charging rovers, and running in-situ resource utilization (ISRU) equipment during the two-week-long lunar night.
The center is actively seeking industry feedback for the system, with key industry days being held at GRC, highlighting its central role in bringing this technology to fruition.
2. Powering the Gateway Lunar Outpost
A key component of the Artemis program is the Gateway, a planned lunar-orbiting space station. GRC is responsible for developing the Power and Propulsion Element (PPE) for Gateway. This element provides the station’s solar-electric power and propulsion, allowing it to move to various orbits around the Moon. GRC’s work on Solar Electric Propulsion (SEP) is what makes this highly efficient, long-duration maneuverability possible.
3. The NEXT-C Ion Thruster Testing
The Evolutionary Xenon Thruster—Commercial (NEXT-C) is a crucial technology being tested at GRC. This advanced ion propulsion system is a vital part of the PPE for the Gateway, offering significantly higher fuel efficiency than traditional chemical rockets. Testing the NEXT-C in GRC’s world-class vacuum chambers ensures its readiness for the deep-space environment.
4. 2025 R&D 100 Award-Winning Space Internet
In a major recent breakthrough, GRC teams earned 2025 R&D 100 Awards. One of the winning projects was a system designed to deliver high-speed internet for space. This technology is a game-changer for space communications, promising to revolutionize how data is transmitted between Earth, the Moon, and future Mars missions, enabling real-time scientific data transfer and high-definition video feeds.
5. Transforming Aviation for Climate Goals
Beyond space, GRC is a leader in aeronautics research, specifically focusing on helping the nation meet its climate goals. This research involves developing quieter, more fuel-efficient aircraft engines and testing advanced materials that can withstand extreme temperatures and pressures, all aimed at reducing the environmental footprint of air travel.
6. Utilizing World-Class Testing Facilities
GRC’s research is enabled by its unparalleled ground test facilities, which are entities in themselves and crucial to NASA’s success. These include the Neil A. Armstrong Test Facility, which houses the Space Environments Complex and the In-Space Propulsion Facility. At Lewis Field, GRC operates a variety of specialized facilities:
- Wind Tunnels: For aerodynamic and propulsion testing.
- Drop Towers: For simulating microgravity environments.
- Vacuum Chambers: Essential for testing space-bound components.
- Chemical Propulsion Research Complex (CPRC): Dedicated to simulated altitude rocket testing.
7. Advancing High-Temperature Electronics
GRC is renowned for its work on silicon carbide (SiC) electronics, which can operate reliably at extremely high temperatures. This technology is vital for components placed near jet engines or within nuclear power systems, where traditional silicon-based electronics would fail. This research enables lighter, more robust systems for both aerospace and deep-space applications, reducing the need for heavy cooling systems.
The Future is Power: GRC’s Role in Deep Space
The strategic direction of the NASA Glenn Research Center is clear: to be the agency’s primary center for the high-power, high-propulsion technologies necessary for long-duration space missions. The center's recent realignment of its operating structure is designed to ensure it remains responsive and efficient in supporting future growth, particularly within the Artemis program.
From the early days of the Lewis Flight Propulsion Laboratory focusing on jet engines to today’s work on Fission Surface Power and Solar Electric Propulsion, GRC has consistently been the proving ground for the most challenging and transformative technologies. Its current projects—which include the Gateway’s lifeblood, advanced space internet, and the promise of nuclear power for a lunar base—cement its status as an indispensable asset in the quest for deep-space exploration and a sustainable future for flight. The innovations coming out of Cleveland and Sandusky are literally powering humanity’s next giant leap.
