Mars Exploration Rovers Update: As Mars Orbits Nearer to Earth, Spirit and Opportunity Rove Onward into New Territories

A.J.S. Rayl • October 27, 2005

The Mars Exploration Rovers science team witnessed a bit of an expansion down here on Earth this month, while up on the Red Planet Spirit and Opportunity continued roving along. As Halloween nears, the twin robot geologists have put in another solid month's worth of work, overcoming every occasional "hiccup." At this point, as Mars' orbit brings it as close to Earth as it will get until the summer of 2018, both Spirit and Opportunity are moving into new territories at their respective inspection sites.

Almost since it was founded in 1980, The Planetary Society has been there for the search for other worlds.

Cassini Poised to Pinpoint Huygens' Landing Site At Last

Emily Lakdawalla • October 26, 2005

I've just posted a very brief update on the upcoming Titan flyby, which will be the first to include RADAR imaging across the Huygens landing site.

An evening with Dava Sobel

I've just come home from Caltech, where I saw author Dava Sobel give a presentation on her latest book, The Planets.

A way-cool Cassini picture: rings, Titan, Dione, Prometheus

I just noticed this picture on the Cassini raw images website. I love these "many worlds" pictures.

NOW Mars is spectacular

Emily Lakdawalla • October 19, 2005

Back in August, there was a false alarm being circulated by email that Mars was going to be super-close to Earth on August 27.

Animation from Cassini's approach to Dione

Emily Lakdawalla • October 12, 2005

The images from Cassini's Dione encounter yesterday have started coming back, and there is a really cool set of 16 pictures of Dione and Rhea.

Dione encounter today

Emily Lakdawalla • October 11, 2005

Cassini is already on its way in to a close, 500-kilometer encounter with Dione -- it's less than four hours away now, at 17:52 UTC.

Hyperion in color

Here is a gorgeous color mosaic of Hyperion assembled by amateur image processor Mattias Malmer from images from the recent flyby.

A new Cassini data release to the Planetary Data System

Emily Lakdawalla • October 06, 2005

Yesterday, this quarter's release of Cassini data showed up at the Planetary Data System (PDS). The PDS is the public repository for all of NASA's data.

A piece of a new picture from Hayabusa

Emily Lakdawalla • October 04, 2005

The Hayabusa mission has proven to be a bit of a tease -- they were releasing lots of images to the public as they approached asteroid Itokawa, but once they arrived, the image releases shut down entirely. There is finally a little postage stamp of an image captured by Hayabusa at "home position," only 7 kilometers from the asteroid, compared here to a picture taken from "gate position," 20 kilometers away.

Amazing views of Hyperion

Emily Lakdawalla • October 01, 2005

I've finally worked my way through all of the Hyperion images that were returned from the last flyby. It's a wonderful data set.
