Abstract: Low-earth-orbit (LEO) satellite constellation design aims to achieve full coverage of the Satellite Internet of Things (SIoT) by optimizing satellite orbits across regions. The time-varying ...

Since it invaded Ukraine in 2022, Russia has worked to develop countermeasures to space-based internet systems—and one such countermeasure may be on display inside Iran.

The proliferated architecture satellites are built by SpaceX and Northrop Grumman. All of them have reached orbit aboard ...

Abstract: Efficient offloading and resource management are critical for LEO satellite-assisted multi-access edge computing (MEC) systems. This letter introduces a collaborative model based on ...

Artist's concept of NASA's Pandora mission, which will help scientists untangle the signals from the atmospheres of exoplanets – worlds beyond our solar system – and their stars. Pandora, the latest ...

The year 2025 ended with more than 14,000 active satellites from all nations zooming around the Earth. One-third of them will soon move to lower altitudes. The maneuvers will be undertaken by SpaceX, ...

Starlink, SpaceX's satellite network, plans to lower its satellite orbits from 550 km to 480 km by 2026 to enhance space safety. This decision follows an incident where a satellite experienced an ...

What just happened? There have been plenty of reports in recent times about near-misses of low Earth orbit satellites – most of them belonging to Starlink. In 2026, Elon Musk's company hopes to reduce ...

SpaceX’s Starlink is preparing a major reconfiguration of its satellite constellation in an effort to improve space safety and reduce the risk of orbital collisions. According to Michael Nicolls, ...

Starlink will begin lowering the orbit of its satellite constellation in 2026, moving spacecraft currently operating at around 342 miles (550 km) down to 298 miles, as the company seeks to improve ...

Starlink will lower the orbits of roughly 4,400 satellites this year as a safety measure, according to engineering VP, Michael Nicolls. In a post on X, Nicolls wrote that the company is "beginning a ...
