As low Earth orbit becomes crowded, very low Earth orbit satellites are emerging as a promising alternative. Operating closer to Earth, they offer faster communication, sharper imaging, and better weather data. Advances in propulsion are helping overcome atmospheric drag, opening the door to wider use of this challenging but valuable orbital region.

SpaceX has launched its first Starlink mission of 2026, sending 29 satellites into low Earth orbit aboard a new Falcon 9 rocket. The booster completed a successful landing at sea, while the mission further expanded the company’s global broadband network, which now serves remote regions with limited internet access.

Astronomers have precisely measured the mass of a rogue planet wandering through the Milky Way using a rare gravitational microlensing event. By combining observations from ground-based telescopes across three continents with data from ESA’s Gaia spacecraft, researchers determined the planet’s distance and found it to be about the mass of Saturn. The discovery pro...
