Vice President Kamala Harris announced the United States’ commitment to not conduct anti-satellite missile tests, making it the first country to institute the self-imposed ban against the destruction of orbitals that jeopardize the long-term sustainability of space.

Harris announced the ban Monday night before soldiers at the Vandenberg Space Force Base after having toured it earlier in the day as the first presidential visit to the base near Santa Barbara of the Biden administration.

Harris said Monday that the United States hopes other nations, whether spacefaring or not, follow it by instituting their own self-imposed anti-satellite missile test bans as it is in the world’s best interest to do so.

“This will benefit everyone, just as space benefits everyone,” she said.

Only the four countries of the United States, China, Russia and India have conducted what are called direct-ascent anti-satellite missile tests when a rocket is fired at an orbital with the purpose of destroying it.

NASA has previously condemned these tests as the space debris they create poses a threat not only to the International Space Station and other satellites but to future space travel.

According to NASA, there are millions of pieces of space debris flying around low-Earth orbit, with some 23,000 pieces larger than a softball, though a collision between even a small piece of debris and a spacecraft could create serious damage.
