The United States will no longer conduct anti-satellite tests, Vice President Kamala Harris announced Monday. With this declaration, the country seeks to establish a new norm for responsible behavior in space.

“We have consistently condemned these tests and called them reckless, but that is not enough,” Harris said. “Today we are going further. I am pleased to announce that as of today, the United States commits not to conduct destructive direct-ascent anti-satellite missile testing. Simply put: These tests are dangerous, and we will not conduct them. We are the first nation to make such a commitment. And I call on all nations to join us.”

Harris made her comments on Monday evening during a visit to Vandenberg Space Force Base, the preeminent launch site on the West Coast of the United States. During her speech, Harris said the US government will work with other nations to establish this as a new international norm for responsible behavior in space, noting that ending such tests would benefit all nations and help to preserve the environment of low Earth orbit.
