Mercury's Weird Terrain

Posted by Emily Lakdawalla on 2011/04/19 11:21 CDT

When Mariner 10 flew past Mercury, it caught an immense impact basin lying half in and half out of sunlight, which they named Caloris. Even with only half the basin visible, scientists knew it was one of the largest in the solar system. Geologists had to wait more than 25 years to see the rest of Caloris, and when they did it turned out to be even bigger than they had thought. But the fact that Caloris was only half in sunlight was fortuitous in one sense, because it meant that the spot on Mercury that was exactly opposite the area of the Caloris impact was also partially in sunlight. That spot looks weird.

I've spent the day noodling around in the current issue of Icarus, following up some of the more interesting stories within its table of contents, and came across a picture of this very cool crater -- actually, set of craters -- on Mars.

Opportunity bags a few craters

Posted by Emily Lakdawalla on 2010/11/10 04:46 CST

In the last few days, Opportunity's passed by several craters, and the rover drivers took advantage of the chance encounters for what they call "drive-by shooting" (a phrase I can't say I'm particularly fond of, but they didn't ask me).

Posted by Amir Alexander on 2010/02/13 12:00 CST

It was January of 2004 when the elegant curve of the Vichada first caught the attention of geologist Max Rocca of Buenos Aires. Could the course of the river have been shaped by the circular outlines of an impact crater? Rocca decided to find out.

A pretty picture of Concepcion crater

Posted by Emily Lakdawalla on 2010/02/01 10:37 CST

It looks like the rover team thinks Concepcion is pretty enough (in both aesthetic and a scientific senses) to be worthy of the full-color Pancam panorama treatment; color frames started arriving on Earth over the weekend.
