Summary
Space debris, also known as space junk, encompasses all non-functional objects orbiting Earth such as defunct satellites, spent rocket stages, and fragments from collisions or disintegrations. Over time, this debris can accumulate and create an increasingly hazardous environment in orbit. Even tiny fragments, traveling at extremely high velocities, can inflict significant damage on operational satellites and spacecraft. If left unmanaged, the density of debris raises the risk of catastrophic collisions and further fragmentation, compounding the problem and threatening the safety and sustainability of space activities.

The Satellites the Size of a Studio Apartment

AST SpaceMobile's BlueBird constellation is a bet that raw aperture size wins. Each satellite unfolds a 64-square-meter phased-array antenna in orbit, the largest commercial antenna ever deployed. The company claims a stock smartphone on the ground can connect directly to it. The competition says the physics doesn't support that. Seventeen satellites in and a contract with AT&T, Verizon, and Vodafone, somebody's math is wrong.
