Citizen Science projects let volunteers easily contribute to active science programs. They're useful when there is so much data it overwhelms computing algorithms (if they exist) or the scientific research team attempting to process it.

Meteorites hit Earth all the time, but they almost never score direct hits on human-built structures (or humans, for that matter). Once in a while, though, direct hits do happen, and it looks like this recent event in Poland was the real thing.

I have always found maps of the motions of Earth's continents fascinating, so it is really cool to see some gorgeous new reconstructions of what Earth would have looked like to spaceborne observers over the last 750 million years.

I wrote the following blog entry about an image from Japan's Daichi Earth-observing orbiter last week as one to keep in my back pocket for a day when I was too busy to write, not anticipating that there'd soon be a more pressing reason to write about Daichi. On April 21, after just over five years of orbital operations, Daichi unexpectedly fell silent, and is probably lost forever.

Might there be many Titan-like planets and moons, with atmospheres and liquid methane rain, rivers, and lakes, across the galaxy? It's an important question if you think that liquid methane environments could support alien life, because it turns out that Titan-like planets might be more common than Earth-like planets.

I was heading south to Tokyo with Seiko and Ishi, two students from the conference. We were planning a dinner together, maybe catching the nighttime skyline from the top of Tokyo Tower. I dozed off as the train flew silently through the countryside. Next thing I knew, Seiko was shaking me awake saying "Earthquake! Earthquake."

As the disaster of the magnitude 8.9 Sendai quake of Friday, March 11, at 05:46:23 UTC continues to unfold in Japan, I have been unable to tear my attention away.

Space probes grant us perspective, the ability to see our place within the vastness of the solar system. But opportunities to see all of the solar system's planets in one observation are rare. In fact, there's only been one opportunity on one mission to see the whole solar system at once, until now.

I couldn't believe these videos when I first saw them: five views from engineering cameras of important events in the Chang'E 2 spacecraft's journey to the Moon.

A good start to my day today: The New York Times' Lens Blog featured the "Martian Moment in Time" photo that Opportunity took last week in a really nice writeup. I'm so grateful, and still a little surprised, that the folks on the Mars Exploration Rover mission took this idea and ran with it!

One of the ways that planetary scientists try to understand the origin and evolution of landforms on other planets is by studying similar kinds of landforms or "analogs" here on the Earth. For the past few days I've been working with a group of colleagues doing just that--specifically, studying dunes in the Great Sand Dunes National Park and Preserve in order to try to better understand the nature of sand dunes on Mars.

From June 21 to July 6, 2006, a four-person team traveled to Borup Fiord Pass to perform geological field studies to compare with satellite images.
