LPSC: Thursday: Rovers, Titan, Mars, Venus Express, Neptune

Posted by Ted Stryk on 2008/03/14 03:49 CDT

I spent a large portion of the day at the Lunar and Planetary Institute's library and presented my own poster during the poster sessions, so my coverage of Thursday's sessions is limited.

White Rock through the ages: Mars Global Surveyor (1997-2006)

Posted by Emily Lakdawalla on 2008/02/22 11:24 CST

We first spotted the strange bright feature colloquially known as "White Rock" in Mariner 9 images from 1972, and revisited it, without learning much more, in Viking images from the late 1970s.

Showing off Saturn's moons

Posted by Emily Lakdawalla on 2008/02/19 04:40 CST

There was a press release from the Cassini mission today about a pile of papers (14 of them!) being published in the journal Icarus about Saturn's icy moons. I haven't had time to read more than the overview article yet, but I wanted to come up with a graphic for an overview of Saturn's moons, and I couldn't resist delving into the massive database of Cassini images to produce something new

"Moon?"

Posted by Emily Lakdawalla on 2008/02/18 09:54 CST

It's a legal holiday here in the U.S. (President's day), and my daughter's babysitter is taking the day off, so I won't be getting much work done today. But I thought I'd check in to share the fact that, as we got out of the car last week, my daughter pointed up in the sky at the crescent moon and said "Dat!" so I gave her the word, "Moon."

Opportunity watches the clouds drift by

Posted by Emily Lakdawalla on 2008/02/12 04:11 CST

Opportunity is now following a rather leisurely autumn schedule, according to the latest update on the mission website. Some of the work Opportunity is doing involves staring skyward, looking for patterns in the clouds that pass overhead at this time of year. One of the guys at unmannedspaceflight.com has put together some nifty animations of the wispy cloud patterns.

While conversing with Ken Edgett about the smiley face on Mars he remarked to me how different Mars looks at different pixel scales, and in particular that there is a transition somewhere in the neighborhood of six to seven meters per pixel.

Finding images from Mars

Posted by Emily Lakdawalla on 2008/02/06 03:10 CST

There have been so many missions to Mars, which have sent back so much data, that figuring out how to find images of places on Mars can be really overwhelming.

Have a happy day on Mars

Posted by Emily Lakdawalla on 2008/02/01 11:36 CST

I thought this was a fun image to kick off the weekend. This isn't the first happy-looking crater to be photographed from Mars, but I really like this one; it's more goofy.

Teeny little Bigfoot on Mars

Posted by Emily Lakdawalla on 2008/01/23 01:41 CST | 3 comments

The story of a Sasquatch-shaped rock visible in a recent panorama from Spirit is getting a lot of play in the mainstream media, but fortunately, it's not being taken very seriously. (My favorite take on this picture is the lead from the Times Online story about it: "Is it a rock? A trick of Martian light on the eye? Or Osama Bin Laden waving from his barren hideout 300 million miles from planet Earth?")
