From Artemis II’s lunar journey to milestone Starlink deployments, this week showcases both the routine and revolutionary sides of modern space exploration.
SpaceX Reaches 10,000 Active Starlink Satellites in Orbit
SpaceX has reportedly achieved a major constellation milestone with its 10,000th active Starlink satellite now in low-Earth orbit. The achievement came through a series of recent Falcon 9 launches, including Tuesday’s twilight mission that deployed 29 satellites and another launch carrying an additional batch to the growing megaconstellation.
The Starlink network operates in multiple orbital shells between 340-570 kilometers altitude, providing global broadband internet coverage. Each satellite weighs approximately 260 kilograms and features advanced ion propulsion systems for orbital maintenance and collision avoidance. The constellation’s rapid growth—from zero to 10,000 active satellites in just over four years—represents the largest commercial satellite deployment in history.
Northrop Grumman Cygnus Cargo Ship Heads to Space Station
A Northrop Grumman Cygnus spacecraft launched aboard a SpaceX Falcon 9 rocket, carrying over 5 tons of critical supplies to International Space Station astronauts. This marks another successful mission under NASA’s Commercial Resupply Services program, demonstrating the growing flexibility of launch providers for station logistics.
The cargo manifest includes scientific experiments, crew provisions, and hardware for ongoing ISS operations. Upon arrival, the station’s robotic Canadarm2 will capture the Cygnus spacecraft and berth it to the Unity module for several weeks of cargo operations before the vehicle’s planned destructive reentry.
Subaru Telescope Discovers Hidden Giant Planet
Japan’s Subaru Telescope has revealed a previously hidden giant planet using advanced direct imaging techniques. The discovery showcases the observatory’s cutting-edge capabilities in planetary science and represents a significant advancement in our ability to detect and characterize exoplanets beyond traditional transit and radial velocity methods.
This detection is part of the National Astronomical Observatory of Japan’s new systematic survey program, designed to push the boundaries of ground-based astronomy. The findings demonstrate how Earth-based telescopes continue to complement space-based observatories in expanding our catalog of worlds orbiting distant stars.
