Space Jam

Space is getting crowded. The biggest challenge is space junk—the debris that results when satellites break up or get shot down. If we aren’t careful, space junk, and space conflict, could cause a lot of problems down here on Earth.

Show Notes

We often envision space as a dark, empty void. But in recent decades, Earth’s orbital zone has become crowded and dangerous. One factor is the proliferation of satellites, many of them privately owned. Another is space junk, or the growing mass of debris left behind when satellites break up or are shot down. Some experts say that, without new rules of the road, space junk—and the militarization of space—could lead to catastrophe.

Center for Preventive Action

The world is entering a new era of great-power competition. As U.S. policymakers look ahead, it pays to know what global threats to anticipate. Every January, the Council on Foreign Relations publishes a survey that analyzes the conflicts most likely to occur in the twelve months ahead and rates their potential impact on the United States. But can the country prepare itself for mass immigration, cyberwarfare, and nuclear tensions while still cooperating with adversaries on global issues such as climate change?

Global Governance

In 2022, several colossal events dominated the headlines, most prominently the war in Ukraine and the worldwide inflation that it helped spark. But beyond Ukraine, events with global implications continued to unfold. In this episode, Why It Matters checks in with three CFR fellows and CFR President Richard Haass to understand the least-covered stories of 2022 and to take a peek at what could await the world in 2023.

Technology and Innovation

For years, the world thought of the internet as a borderless zone that brought people from around the world together. But as governments pursue very different regulatory paths, the monolithic internet is breaking apart. Now, where there had been one, there are at least three internets: one led by the United States, one by China, and one by the European Union.
