Page 7: Research news on Artificial satellites

Artificial satellites as a research area encompasses the scientific and engineering study of human-made objects intentionally placed into Earth or other celestial orbits for observation, communication, navigation, and experimentation. Research focuses on orbital dynamics and mission design, attitude determination and control, space environment interactions (radiation, plasma, micrometeoroids), and advanced materials and power systems for long-duration operation. It also includes development of miniaturized platforms (e.g., CubeSats), payload instrumentation for remote sensing and scientific measurements, formation flying and constellations, on-orbit servicing, autonomy and fault management, and the impacts of satellite proliferation on space traffic management and orbital debris mitigation.

Satellites help tackle landfill methane leaks

Satellites are emerging as a powerful new tool in the fight to curb emissions of methane. While methane is much shorter-lived in the atmosphere than carbon dioxide, it is vastly more potent at trapping heat, which makes rapid ...

Reading the 'light fingerprints' of dead satellites

There are already tens of thousands of pieces of large debris in orbit, some of which pose a threat to functional satellites. Various agencies and organizations have been developing novel solutions to this problem, before ...

Sun-watcher SOHO celebrates 30 years

On 2 December 1995, the ESA/NASA Solar and Heliospheric Observatory (SOHO) blasted into space—on what was supposed to be a two-year mission.

What time is it on Mars? Physicists have the answer.

Ask someone on Earth for the time and they can give you an exact answer, thanks to our planet's intricate timekeeping system, built with atomic clocks, GPS satellites and high-speed telecommunications networks.

High-resolution radar satellites launched for Greece

Thanks to the Recovery and Resilience Facility, and through collaboration between the Greek government, the private satellite company ICEYE and the European Space Agency (ESA), two new high-resolution radar satellites have ...

How mega-constellations are learning to manage themselves

Satellite mega-constellations are quickly becoming the backbone of a number of industries. Cellular communication, GPS, weather monitoring and more are now, at least in part, reliant on the networks of thousands of satellites ...
