Page 15: Research news on Remote sensing

Remote sensing as a research area focuses on the acquisition, processing, and interpretation of information about the Earth or other targets without direct contact, primarily using sensors mounted on satellites, aircraft, drones, or ground-based platforms. It encompasses the study of electromagnetic radiation interactions with atmosphere, land, water, and biosphere, including multispectral, hyperspectral, radar, and LiDAR techniques. Research addresses sensor design, radiometric and geometric calibration, atmospheric correction, image fusion, and advanced retrieval algorithms for biophysical and geophysical variables. Applications span environmental monitoring, land-use and land-cover mapping, climate and cryosphere studies, hazard assessment, and support for geospatial modeling and data assimilation.

NASA tech to use moonlight to enhance measurements from space

NASA will soon launch a one-of-a-kind instrument, called Arcstone, to improve the quality of data from Earth-viewing sensors in orbit. In this technology demonstration, the mission will measure sunlight reflected from the ...

Orbiter pair expands view of Martian ionosphere

Like Earth, Mars is surrounded by an ionosphere—the part of its upper atmosphere where radiation from the sun knocks electrons off of atoms and molecules, creating charged particles. The Martian ionosphere is complex and ...

Hyperspectral sensor pushes weed science a wave further

By combining artificial intelligence and sensors that can see beyond visible light, Arkansas researchers have developed a system that exceeds human discernment when it comes to measuring herbicide-induced stress in plants.

Why MTG-S1 is a nowcasting game-changer

From an orbit 36,000 km from Earth, the Meteosat Third Generation Sounder satellite (MTG-S) is set to revolutionize the way we forecast severe weather. Unlike the imaging satellites, which complete the constellation of the ...

A breath of fresh data: Sentinel-4 innovates for clean air

From its vantage point outside Earth's atmosphere, more than 36,000 km above Earth's surface, the Copernicus Sentinel-4 mission will detect major air pollutants over Europe in unprecedented detail. It will observe how they ...

Martian probe rolls over to see subsurface ice and rock

The Mars Reconnaissance Orbiter (MRO), launched by NASA in 2005, is orbiting Mars tasked with studying its atmosphere, surface, and subsurface in unprecedented detail. Equipped with a suite of advanced instruments—including ...
