Reveal Unexpected Mineralogy A team of astronomers from Caltech analyzed near‑infrared data from JWST for three inner satellites—Larissa, Galatea, and Proteus. The extreme distance and faintness of these moons have long hindered detailed compositional...

AI4 Space Safety and Sustainability (AI4S3), aims to mitigate the rising risks associated with the proliferation of satellites. Developed by the Alan Turing Institute’s Defence AI Research Centre (DARe), the project represents a collaborative effort...

Force – © Wikimedia Commons Beyond Kinetic Warfare The term “space weapon” often conjures images of missiles destroying satellites, but modern orbital conflict is increasingly centered on non-destructive disruption. The U.S. Space Force noted that...

of light. As the population of low Earth orbit continues to surge—with the European Space Agency reporting roughly 18,340 satellites currently in orbit as of June 2026—these photobombing spacecraft have become a critical obstacle for ground-based...

New orbital mirror test aims to prove satellites can safely redirect sunlight to Earth, paving way for groundbreaking solar‑lighting technology. The U.S. government has granted permission for a pioneering satellite experiment that will test the ability...

Europe’s new mission will test if satellites can tap the upper atmosphere for propulsion, enabling them to stay in ultra‑low Earth orbit. Kreios Space, a Spanish start‑up, is gearing up for a landmark in‑orbit test that could reshape how satellites...

Journey of Satellite Signals To understand the design of a satellite dish, we must begin with the signals themselves. Satellites orbiting thousands of kilometers above Earth transmit microwaves toward the planet. These signals travel through the vacuum...

massive asteroid will sweep closer than many satellites, creating a rare sky event Asteroid Apophis will skim the Earth at roughly 32,000 km on 13 April 2029, an altitude lower than many geosynchronous satellites. Although the object will not collide...

AO first reduces the bulk of the distortion, after which MDR captures the residual scattered component. Geostationary satellites orbit the earth at 36 000 km while the emerging breed of low and medium earth orbiting satellites (LEOs and MEOs) orbit the...

breakup of the Yaogan-50 (02) spacecraft has complicated an already congested orbital environment, creating new risks for satellites operating in a particularly sensitive region of low Earth orbit. The Yaogan-50 (02) satellite was launched on March 15,...

laser-ranging data, researchers have proposed a way to transform the Earth-Moon system—along with artificial satellites and distant binary pulsars—into an observatory capable of probing a frequency band that has remained frustratingly out of reach for...

Sailors have long reported glowing ocean patches; modern satellites now probe the phenomenon, but the cause remains elusive. Mariners have long described eerie, expansive sheets of light that turn the night sea into a luminous plain. These rare...

Satellites and old ship logs map the mysterious milky seas—vast glowing oceans that may signal a hidden environmental threat. Sailors have long spoken of a nocturnal ocean that turns a luminous cream, bright enough to read by, and stretches to the...

is its role in space exploration. Since the 1970s, it has served as the designated spacecraft cemetery for decommissioned satellites, rockets, and space station components. This practice stems from Point Nemo’s extreme isolation, making it a safe zone...

of unidentified anomalous phenomena, revealing hidden secrets of that era. In the mid-twentieth century, long before satellites began circling the Earth, astronomers photographed the heavens using glass plates that recorded the light of millions of...

rotating the platform. Reflect Orbital’s rollout plan envisions two test units in 2026, scaling to more than a thousand satellites by 2028, and deploying upwards of 50 000 mirrors by 2035. At full scale, the network could generate illuminance levels...

the atmosphere and surface across diverse regions. These mobile platforms enable data collection at spatial scales that satellites cannot resolve. While satellites excel at providing worldwide coverage, airborne missions can zero in on specific...

international push toward orbital computing. China’s ADA Space, in partnership with Zhejiang Lab, has already launched satellites for its “Three‑Body Computing Constellation,” and U.S. firms such as SpaceX, Starcloud, and Blue Origin are seeking...

In a region where on‑the‑ground access is limited, data from Europe’s Sentinel‑1 constellation and Italy’s COSMO‑SkyMed satellites delivered a high‑resolution picture of the evolving surface deformation. InSAR satellite data showing ground deformation...

next‑gen robotic satellite servicing. NASA has lifted off a pioneering project that could reshape how we maintain satellites while safeguarding one of the most productive space observatories. The agency says the newly deployed LINK vehicle will meet the...
