Perspective | The Dominance of U.S. in Space Exploration is Under Threat


The article, written by Bethany Ehlmann, a professor of planetary science, emphasizes the importance of space exploration for the U.S. and the world. However, it also highlights the current challenges faced by the U.S. space program due to budget stalemates and job cuts. Particularly, over 500 staff members at NASA’s Jet Propulsion Laboratory (JPL) were recently laid off, jeopardizing the U.S.’s leadership in deep space exploration.

At the same time, China’s space agency is making significant strides in its lunar exploration efforts, with its Queqiao-2 relay satellite set to support a groundbreaking mission to return samples from the far side of the moon.

The U.S. space program’s current predicament stems from a budget impasse between the House and Senate over funding priorities, resulting in a deficit of over $500 million for solar system exploration. This situation has sparked internal rivalries for the remaining funding and disrupted U.S. deep space exploration.

The author argues that this disruption comes at a critical time when the field of space exploration offers more exciting opportunities than ever, with many international programs and private companies launching successful deep space missions. Additionally, NASA’s Artemis program aims to take humans to the Moon and Mars, and the James Webb space telescope is providing valuable data.

Despite these challenges, there is a clear roadmap for the future. The National Academies recently completed a new Decadal Survey for planetary science and astrobiology, outlining an ambitious 10-year plan for U.S. leadership in space science. However, this leadership is at risk due to the ongoing budget stalemate.

To maintain U.S. space leadership, the author urges Congress to fund NASA’s Science Mission Directorate at the planned fiscal year 2024 levels or at least at the continuing fiscal year 2023 levels. They also call for a balance between human and robotic exploration and stress the importance of programs like Artemis and Mars Sample Return.

The author concludes by emphasizing the societal benefits of space exploration, likening space missions to modern-day cathedrals and generational endeavors. They argue that these missions inspire the next generation, showcase American ingenuity, and facilitate peaceful international collaborations. Therefore, the author urges U.S. leaders to support the space workforce and show the willpower to continue leading global space exploration.
