What's the best design for a flying Mars robot?

Building a flying vehicle for Mars would have significant advantages for exploration of the surface. However, to date, all of our surface exploring vehicles and robotic units on Mars have been terrestrial rovers. The problem ...

Study discovers high levels of air-cleansing compound over ocean

(Phys.org)—Researchers have detected the presence of a pollutant-destroying compound iodine monoxide in surprisingly high levels high above the tropical ocean, according to a new study led by the University of Colorado ...

Exoplanet aurora: An out-of-this-world sight

Earth's aurorae, or Northern and Southern Lights, provide a dazzling light show to people living in the polar regions. Shimmering curtains of green and red undulate across the sky like a living thing. New research shows that ...

Researchers reveal stratospheric air intrusion process

Long-term monitoring of radionuclides transported with through the atmosphere can help to reveal atmospheric dynamics. The cosmogenic 10Be/7Be ratio is an effective tracer of atmospheric motion.

Ski jump: Flying or falling with style?

If you or I jump in the air as high as possible, we can stay off the ground for about half a second. Michael Jordan could stay aloft for almost one second. While there are many events at the Winter Olympics that feature athletes ...

Amazonian river winds unraveled by air pollution observations

River winds are induced by the daily thermal contrast between the land and the river. During the daytime, warmer temperatures over the land lead to lighter air masses that are lifted. The air masses in turn drive onshore ...
