Scientists Track Dust Storms From Space

Image credit: NASA
NASA-funded scientists have proven that storms in China can spread dust incredible distances in a relatively short time; over 20,000 kilometres travelling from Asia, to North America, then Greenland, and even reaching the French Alps. Red dust had been discovered in the Alps over 20 years ago, but the actual origin hadn’t been tracked until now. Several computers models were used to simulate the movement of dust in the atmosphere.

Lunar Eclipse Puts on a Show

People with clear skies Thursday night were treated to a total lunar eclipse. The eclipse began at 0203 (10:03pm EDT) and ended approximately three hours later. The weather wasn’t entirely cooperating; however, many astrocameras poised around North America and Europe ended up being rained out. The next lunar eclipse will be on November 9, 2003, and will be visible from roughly the same parts of the Earth – only this time it’ll be brighter.

NASA Orders Prototype Martian Airplane

Image credit: NASA
After a series of successful tests with a half-sized prototype, NASA has ordered a full-scale prototype of the Ares (Aerial Regional-scale Environmental Survey of Mars), aircraft, designed to help explore the surface of Mars. If all goes well, the aircraft will be launched to Mars in 2007. When it arrives in 2008, it will enter the atmosphere, deploy its wings and fly 850 kilometres along a route that takes it past the terrain that NASA scientists want to observe.

Hubble Sees Springtime on Neptune

Image credit: Hubble
New photos of Neptune taken by the Hubble Space Telescope seem to indicate that the planet is entering its version of Spring. By comparing photos taken in 1996, Astronomers believe that bands across the planet are getting wider and brighter, which seems to be a response to increased sunlight. Like the Earth, Neptune is believed to have four seasons, but since the planet takes 165 years to orbit the Sun, they last decades, not months.
