Researchers used a pair of powerful supercomputers to simulate the potential trajectories of 1 million satellites in a ...

Space is getting crowded — nowadays, over 45,000 human-made objects orbit Earth. A portion of that figure is indeed ...

By Shreepoorna S Rao For the last thirty years, most of the world’s Earth data has come from satellites. That architecture ...

Lawrence Livermore National Laboratory creates a cislunar orbit map to help predict satellite stability and improve collision avoidance in increasingly crowded Earth orbits.

Researchers at The University of Manchester have developed a new way to design Earth-observation satellite missions that could help protect the space environment while continuing to deliver vital data ...

If executed at the scale, Musk's orbital data center plan could have devastating effects on the environment and the ...

On Jan. 31, 1958, Explorer 1 became the first satellite launched by the United States. Its primary science instrument, a cosmic ray detector, was designed to measure the radiation environment in Earth ...

Planned launch of 500,000 satellites could spoil about one in three Hubble images, even when the telescope stays above Earth's weather.

Low Earth orbit is no longer a quiet frontier. With thousands of commercial spacecraft circling just a few hundred kilometers above our heads, scientists now warn that a runaway chain of collisions ...

More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and what scientists have learned is remarkable. The South Atlantic Anomaly, a ...

Look up on a clear night, and you might catch a strange kind of light show. A glowing streak of light, moving slower than a meteor, disintegrates piece by piece. That’s not a comet or a shooting star ...

The CRASH Clock is a new predictor of how much time there will be before a collision if a solar storm knocks out power and ...
