“Faster ice melting under global warming was the most likely cause of the directional change of the polar drift in the 1990s.” Since 1980, the planet’s north and south poles have moved roughly four meters in distance, and new research shows that shifts in the Earth’s rotational axis have accelerated since the 1990s as a […]
The U.S space agency NASA says its Perseverance rover has converted carbon dioxide (CO2) in the Martian atmosphere to oxygen, a critical step toward future human exploration of Mars. NASA on Monday said a toaster-size, experimental instrument on the rover called the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE), produced about 5.4 grams of […]
NASA’s Ingenuity Mars Helicopter captured this shot as it hovered over the Martian surface on Apr. 19, 2021, during the first instance of powered, controlled flight on another planet. (NASA/JPL-Caltech) The U.S. space agency, NASA, Monday received images and data confirming its small helicopter, Ingenuity, successfully performed the first controlled powered flight of an aircraft […]
Lightning strikes in the Arctic tripled from 2010 to 2020, a finding University of Washington researchers attribute to rising temperatures due to human-caused climate change. The results, researchers say, suggest Arctic residents in northern Russia, Canada, Europe and Alaska need to prepare for the danger of more frequent lightning strikes. The study, published March 22 in […]
