Hurricanes, As Viewed From Orbit

"Hurricane Ike just rolled across Cuba, and soaked parts of Haiti - both regions still reeling from recent Hurricane Gustav. Ike appears to be weakening now, but is headed tward the Gulf Coast of the U.S., and may yet strengthen. The crew aboard the International Space Station was able to take a photo of Ike from 220 miles overhead last Thursday - one in a long series of great NASA photographs of hurricanes from space. Here are some of the best, from the past several years."

Martian Skies

"What more do we know about Mars' atmosphere? It's hundreds of times thinner than Earth's atmosphere and is made of 95% carbon dioxide, 3% nitrogen, 1.6% argon, and contains traces of oxygen, water, and methane. We also know, from observations that it can support dust storms, dust devils, clouds and gusty winds. With an amazing number of six current live probes exploring Mars (two rovers, a lander, and three orbiters), there are many thousands of images available. Only a few, however show atmospheric phenomena. Presented here are some of the best images of Martian atmosphere (and beyond) in action."

Pow! Right To The Moon


"Scientists are priming two spacecraft to slam into the moon's South Pole to see if the lunar double whammy reveals hidden ice water. The Earth-on-moon violence may raise eyebrows, but NASA's history shows that such missions can yield extremely useful scientific observations."
