Satellites

An old Soviet satellite has fragmented into multiple pieces in low Earth orbit, the latest in a string of recent breakup events.

If the increase in rocket launch frequency continues as it has for the last several years, the risk of falling space debris killing someone on the ground will rise as well, experts say.

The UN's International Court of Justice could help stop the uncontrolled proliferation of satellites in Earth's orbit, which threatens to erase stars from the sky, astronomers hope.

A prototype satellite that will test hardware for Google's planned Project Suncatcher AI constellation will launch aboard a SpaceX rocket next week, if all goes to plan.

The U.S. Space Force is opening up about its operation of orbital weapons, "that can defend the joint force against space-enabled attacks."

A satellite's view from above fills the gaps in our understanding of the grim realities of war and makes it harder for totalitarian regimes to hide their crimes. But challenges exist.

Two spacecraft operated by the company Impulse Space pulled off an impressive orbital feat recently, coming within less than 650 feet of each other.

United States Space Command just held its first-ever "Apollo Maneuvers" exercise, which saw spacecraft maneuvering in orbit through simulated contested environments.

A team of researchers just chased a pair of reentering satellites in a private jet to learn about the pollution caused by space debris burning up in Earth's atmosphere.
