Satellite burn-ups, especially from SpaceX's Starlink constellation, release tons of metals like aluminum oxide into the mesosphere daily. This human-made injection now rivals or exceeds natural cosmic dust inputs, raising concerns about ozone depletion and orbital debris. Scientists warn of parallels to past environmental damage in oceans and the atmosphere.

Blue Origin has announced that its next New Glenn rocket launch will reuse a booster from a recent mission, marking a rapid turnaround in orbital rocket reuse. The NG-3 mission, set for no earlier than late February, will deploy a communications satellite for AST SpaceMobile from Cape Canaveral. This follows the successful NG-2 flight in November and highlights the company's progress toward faster launch cadences.

Scientists at the University of Kentucky have developed a technique called Alternating Magnetic Field Forces (AMFF) that allows satellites to communicate and adjust positions using magnetic fields without interfering with others. This method aims to extend mission lifespans by replacing limited propellant fuel with renewable solar power. Tests on Earth demonstrated successful control of three satellites at precise distances.

SpaceX's Starlink plans to lower the orbits of about 4,400 satellites from 342 miles to 298 miles this year to enhance space safety amid growing orbital congestion. The move, announced by engineering vice president Michael Nicholls, aims to reduce collision risks and speed up deorbiting during the approaching solar minimum. It follows recent near-misses and a satellite anomaly, highlighting challenges in low-Earth orbit.
