The recent National Academies of Sciences, Engineering, and Medicine report, NASA at a Crossroads: Maintaining Workforce, Infrastructure, and Technology Preeminence in the Coming Decades, outlines the key obstacles NASA must overcome to stay at the forefront of space exploration and technological innovation. The report highlights NASA’s need to address pressing issues related to workforce, infrastructure, and technology investment. By doing so, NASA can continue to inspire the world with its bold achievements while maintaining its status as a cornerstone of U.S. scientific and technological preeminence.

The report delves into specific recommendations for addressing these challenges, focusing on long-term planning, strategic investments, and operational reforms. This article explores the key findings of the report, emphasizing how NASA’s future success hinges on its ability to adapt to new challenges while leveraging its existing strengths.

NASA’s Four Pillars of Success: Workforce, Infrastructure, Technology, and Funding

NASA’s success in the past and future is built on four critical pillars: a talented and skilled workforce, state-of-the-art infrastructure, advanced technology, and adequate financial resources. These foundational elements have enabled NASA to take on groundbreaking missions, solve complex scientific challenges, and maintain a leadership role in global space exploration. However, all four pillars are currently under strain, with risks growing that NASA may fall behind if corrective actions are not taken soon.

Workforce: The Challenge of an Aging Talent Pool and Competition for Top Talent

One of the most pressing concerns is the state of NASA’s workforce. NASA has long been known for attracting some of the brightest minds in science, engineering, and technology. However, the agency now faces significant demographic and recruitment challenges. A large percentage of NASA’s workforce is nearing retirement, with many employees expected to retire in the next decade. This impending loss of institutional knowledge and technical expertise represents a major risk for the agency’s future operations.

Furthermore, NASA must compete with a rapidly evolving private space industry that is offering higher salaries and more opportunities for technical professionals to engage in cutting-edge work. Companies like SpaceX, Blue Origin, and others have emerged as significant players in the space industry, creating more competition for highly skilled engineers, scientists, and technologists. This shift is particularly concerning in an environment where NASA’s own compensation packages are often lower than those offered in the private sector, making it harder to attract and retain top talent.

The report emphasizes the need for NASA to expand its hiring flexibility and streamline its recruitment processes. Currently, NASA’s hiring process is lengthy, with an average of 81 days to complete a hire. This lag time places NASA at a disadvantage compared to private companies that can make hiring decisions much faster. While the NASA Flexibility Act of 2004 has provided the agency with special hiring authorities to improve its recruitment process, these measures are still inadequate for the scale of NASA’s needs.

To address these challenges, the report recommends that NASA invest more in workforce development, particularly in offering more hands-on technical opportunities for employees. One key issue raised by NASA staff is that the agency has shifted away from direct technical work and is increasingly reliant on overseeing contractors. While this trend can be efficient, it has led to dissatisfaction among employees who desire more involvement in actual engineering and technological development. By creating more opportunities for direct engagement in technical projects, NASA can better retain its most talented employees and cultivate a new generation of engineers and scientists.

In addition to recruitment and retention, NASA must also focus on improving the diversity of its workforce. While the agency has made progress in recent years, more work is needed to ensure that women, minorities, and other underrepresented groups are well-represented in NASA’s technical fields. A more diverse workforce will not only ensure that NASA draws from the best talent pool available but will also position the agency as a more inclusive and equitable place to work.

Infrastructure: Overdue Modernization and Deferred Maintenance

NASA’s physical infrastructure is another area of significant concern. Many of NASA’s facilities, including critical research laboratories, testing centers, and operational headquarters, are beyond their original design life. As of 2024, approximately 83% of NASA’s facilities are considered outdated, posing a major risk to NASA’s ability to perform at its highest level. The backlog of maintenance and repair work is growing, and some of NASA’s most important facilities are at risk of failing at critical moments, potentially jeopardizing upcoming missions.

One specific area of concern is NASA’s Deep Space Network (DSN), which provides communication capabilities for all missions beyond low-Earth orbit. The DSN’s capacity is currently strained and ill-equipped to handle the demands of future missions, such as those planned under the Artemis program and future Mars exploration efforts. As NASA prepares for a new era of space exploration that includes sending humans to the Moon and Mars, the DSN’s aging infrastructure could create significant delays and risks for these missions.

The report recommends that NASA establish a working capital fund to address its growing maintenance backlog and fund the modernization of its most critical infrastructure. This fund would allow NASA to address urgent needs while developing a long-term plan for upgrading its facilities. Furthermore, the report calls for NASA leadership to prioritize infrastructure investment in a way that balances short-term mission goals with the agency’s long-term ability to maintain state-of-the-art facilities.

Beyond physical buildings, the modernization of key technologies and facilities must be a top priority. From wind tunnels used for aeronautics research to spacecraft integration centers, NASA’s ability to stay at the cutting edge of space exploration depends on having world-class facilities. The report stresses that if NASA continues to defer maintenance and upgrades, the agency risks not only falling behind technologically but also jeopardizing its ability to complete future missions on time and within budget.

Technology Development: A Decline in Research Investment

NASA’s leadership in space exploration has always been tied to its ability to develop cutting-edge technology. However, the report notes that investments in research and technology development have not kept pace with the increasing complexity of NASA’s missions. While NASA has continued to fund mission-specific technology development, the agency has made fewer investments in foundational research that could lead to transformative innovations.

The report points out that critical technologies, such as in-space propulsion, radiation protection for astronauts, and planetary landing systems, are underfunded, threatening the success of future missions to the Moon and Mars. These technologies are essential for enabling long-duration human spaceflight, such as missions to Mars, but they require significant investment in the early stages of development to reach maturity in time for planned missions.

One of the key concerns raised in the report is NASA’s increasing reliance on milestone-based contracts for low-technology-readiness-level (TRL) missions. While this approach can be effective for certain types of work, overreliance on such contracts can erode NASA’s in-house technical capabilities. If NASA outsources too much of its early-stage technology development, the agency risks losing its edge in innovation and becoming overly dependent on external contractors.

To reverse this trend, the report calls for a significant increase in investments in early-stage research and development. Specifically, NASA should prioritize Internal Research and Development (IR&D) programs that allow the agency to explore high-risk, high-reward technologies. These investments are essential for maintaining NASA’s leadership in space exploration and ensuring that the agency has the technological tools necessary to remain at the forefront of space exploration.

The report also stresses that NASA must strike a balance between managing mission risk and fostering innovation through advanced research and development. Historically, NASA’s greatest achievements have come from its willingness to take calculated risks, whether landing a rover on Mars or sending astronauts to the Moon. However, as the agency has matured, it has become more risk-averse, particularly in terms of technology development. While it is essential for NASA to maintain strict safety protocols, particularly for human spaceflight, the agency must also be willing to embrace risk in its research programs to drive transformative advancements.

NASA’s leadership has recognized the need to rejuvenate its research and development (R&D) capabilities, but the challenge lies in securing consistent and sufficient funding to support these initiatives. The report calls for a significant increase in NASA’s internal investment in research, particularly in early-stage, high-risk projects that have the potential to lead to game-changing technologies. By doing so, NASA can maintain its leadership in the global space industry, ensuring that it has the technological tools necessary to remain at the forefront of space exploration.

International Competition and Collaboration

The global landscape of space exploration has shifted dramatically in recent years. While NASA has long been the undisputed leader in space exploration, other nations have made significant strides in their space capabilities. In particular, China has emerged as a formidable competitor, with achievements such as landing a rover on Mars, placing its own space station in orbit, and conducting a mission to the far side of the Moon to collect and return samples—something no other nation has accomplished.

This increasing international competition poses both challenges and opportunities for NASA. On the one hand, NASA must contend with the reality that other nations, particularly China, are closing the gap in terms of technological capability and ambition. On the other hand, there are opportunities for international collaboration that could enhance NASA’s ability to achieve its goals. The International Space Station (ISS) is a prime example of how international cooperation can yield significant scientific and technological benefits.

The report emphasizes that NASA must carefully navigate its relationships with international partners and competitors. While collaboration can provide access to additional resources and expertise, it is also important for NASA to maintain its technological independence and leadership. The agency must strike a balance between working with international partners and maintaining a strong domestic R&D base that ensures the United States remains at the forefront of space exploration.

The Role of Private Industry in Space Exploration

Another significant shift in the space industry is the increasing role of private companies in space exploration. Firms like SpaceX, Blue Origin, and others have fundamentally changed the space landscape by developing innovative technologies and reducing the cost of spaceflight. NASA has embraced this trend by partnering with private companies through programs like the Commercial Crew Program, which has successfully transported astronauts to the ISS aboard privately built spacecraft.

While these partnerships have been successful, the report cautions that NASA must not become overly reliant on private industry for critical technologies and capabilities. There is a risk that if too much responsibility is shifted to private companies, NASA may lose its ability to develop and maintain critical technologies in-house. The agency’s ability to oversee complex missions and provide technical insight could be compromised if too much of the work is outsourced.

The report recommends that NASA continue to foster partnerships with private companies but ensure that it retains control over the development of mission-critical technologies. By maintaining a strong in-house capability, NASA can ensure that it remains a leader in space exploration while leveraging the innovations and efficiencies that private industry can provide.

Financial Considerations: The Need for Increased and Consistent Funding

One of the overarching themes of the report is the need for increased and consistent funding to support NASA’s long-term goals. NASA’s budget has remained relatively flat in real terms for decades, even as the complexity and cost of its missions have increased. This mismatch between budget and mission requirements has led to several high-profile cost overruns and delays, as seen with the James Webb Space Telescope and the Mars Sample Return mission.

The report calls for a reevaluation of NASA’s budget priorities, suggesting that more funding needs to be allocated to workforce development, infrastructure modernization, and early-stage research. While missions like Artemis and the Mars exploration program are critical, the report argues that NASA must invest in the foundational elements that will enable these missions to succeed in the long term. This includes ensuring that NASA’s workforce has the technical skills and hands-on experience necessary to lead future missions, upgrading infrastructure to support new technologies, and increasing investment in cutting-edge research.

Moreover, the report stresses the importance of financial stability for NASA. In recent years, NASA has faced significant uncertainty regarding its budget, with delays in appropriations and the lack of long-term authorization acts creating challenges for planning and execution. The report recommends that Congress work with NASA to provide more consistent and long-term funding commitments. This would allow the agency to plan its missions more effectively and avoid the disruptions caused by year-to-year budget fluctuations.

The Need for a Long-Term Strategic Plan

Perhaps the most important recommendation in the report is the need for NASA to develop a comprehensive, long-term strategic plan that aligns its workforce, infrastructure, and technology investments with its mission goals. The report notes that while NASA has articulated ambitious goals, particularly in the context of the Artemis program and the goal of sending humans to Mars, there is often a lack of detailed planning to support these goals.

For example, the Moon to Mars mission framework lacks the detailed timelines and resource planning necessary to ensure that critical capabilities are developed and ready when needed. The report argues that NASA needs to adopt a more rigorous planning process that identifies specific milestones, technology requirements, and workforce needs over the coming decades. By doing so, NASA can ensure that it is adequately prepared to meet its long-term objectives.

The report also emphasizes the importance of regular updates to this long-term plan. As the global space landscape evolves, NASA must remain agile and adaptable. A strategic plan that is regularly updated will allow NASA to respond to new opportunities and challenges, ensuring that it remains at the forefront of space exploration.
