Mapping Antarctic Specially Protected Areas (ASPAs) remains a critical yet challenging task, especially in extreme environments like Antarctica. Traditional methods are often cumbersome, expensive, and risky, with limited satellite data further hindering accuracy. This study addresses these challenges by developing a workflow that enables precise mapping and monitoring of vegetation in ASPAs. The processing pipeline of this workflow integrates small unmanned aerial vehicles (UAVs)—or drones—to collect hyperspectral and multispectral imagery (HSI and MSI), global navigation satellite system...

In the Mars analog of the Atacama Desert, scientists tested the current instruments used by NASA's Curiosity and Perseverance rovers. They discovered that current Mars rovers are doubtful to detect life on the planet's surface. Read more.

Robotic rovers are exploring the surface of Mars. Part of a rover's mission is to survey the planet for signs of life. There might be nothing to find -- but what if there is, and the rovers just can't "see" it?

Scientists think Mars rovers may have some blind spots when it comes to finding signs of life. Shutterstock Robotic rovers are currently exploring the surface of Mars. Part of a rover’s mission is to survey the planet for signs of life.

Harvard study: Ice sheet collapse in Antarctic would result in more sea level rise than expected Charlie McKenna © AP This undated handout photo provided by NASA shows the Thwaites Glacier in West Antarctic. The global sea level will rise higher than previously expected if the West Antarctic Ice Sheet collapses, according to a new study from Harvard researchers. The study, published in the journal Scientific Advances on April 28, was led by graduate students Linda Pan and Evelyn Powell. Pan and Powell found the ocean level would rise an additional meter, or about 3 feet, hi...
