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.

There was a big news splash about two articles that appeared in Nature about Mars Exploration Rover Opportunity's landing site. The articles suggest two theories for the formation of the layered sulfur-rich deposits at Meridiani Planum that do not involve standing liquid water.

While I was at the Division of Planetary Sciences meeting in Cambridge in September I had a chance to chat with David Atkinson, who's a member of the Doppler Wind Experiment team on Huygens. They and the other instrument teams have been plugging away at analyzing their data.

Since the discovery of 2003 UB313, larger than Pluto, there's been a lively debate going on in many places about what makes a planet. There's now an article in Nature talking about a proposal that would address the controversy

When Deep Impact crashed into the nucleus of Tempel 1 at 23,000 miles per hour on July 4, it sent a huge, bright cloud of stuff upward and outward from the comet, providing a spectacular image that is already assured a place in the space history books, and may well be seared into the brains of all those who watched the event.

"Our cratering experiment went very very well," reported impact scientist Peter Schultz in what may have been the understatement of the weekend. A first look at early science results from the mission suggest that while some events unfolded according to scientists' predictions, Tempel 1 provided many enticing surprises as well.

NASA's Deep Impact spacecraft is set for its date with Comet Tempel 1. "We are going to hit a bullet with another bullet while watching from a third bullet," said Charles Elachi, the head of JPL.

The Cassini imaging team has released an image containing a feature unlike any other that they have seen on Titan. The very dark color, curvaceous outline, and sharp edge of the feature have led them to the conclusion that it could well be the long-theorized but never-before-seen body of liquid hydrocarbons on the surface of Titan.

Earth's radio astronomers have saved the day for one of the Huygens instrument teams. Today, the Doppler Wind Experiment (DWE) team announced their first science results, despite losing nearly all of their expected data.

This morning, asteroid 4179 Toutatis was so close to Earth that simultaneous observations from two telescopes in the same country could show parallax that is obvious even to the least experienced observer. The two telescopes belong to The European Southern Observatory and are located at La Silla and Paranal in Chile

On Wednesday, September 29, Earth will dodge a cannonball: the Near-Earth Asteroid known as 4179 Toutatis will buzz by at a distance only four times the distance from the Earth to the Moon -- about one and a half million kilometers, or about a million miles. But, as the wisdom goes, "close" only counts in horseshoes and hand grenades; Toutatis' flyby will have no effect whatsoever on us.
