Encouraging motion on Spirit

Emily Lakdawalla • November 19, 2009

It really looks like the second attempt at driving Spirit out of the trap has had the hoped-for result: some forward progress (maybe about a centimeter), and no evidence for further downward sinking.

Space Imaging II: Getting Started with MER and Cassini Raw Images now available for download

Emily Lakdawalla • November 19, 2009 • 2

I probably crammed too much into today's class: an hour-and-a-half whirlwind tour through the cameras on the rovers and Cassini, how to access their raw images on the Internet, and some basic processing that you can do with each of them.

Hayabusa's still coming home: JAXA engineers come up with yet another creative solution

Emily Lakdawalla • November 19, 2009

Trouble has come time and again to JAXA's little Hayabusa asteroid sample return mission, yet the mission's engineers always come up with new and creative ways to solve problems.

Opportunity's poking at Marquette Island; Cassini's catching dancing moons

Emily Lakdawalla • November 18, 2009

Since tomorrow's class is going to be on playing with raw images from the rovers and Cassini, I've been playing with recent raw images from the rovers and Cassini! I just thought I'd share a couple of the fun items I've been working with.

Results of the first "Free Spirit" extrication drive, sol 2088: not much, as expected

Emily Lakdawalla • November 17, 2009

Even though all of us rover fans know that Spirit is really, really stuck, I think I'm not the only one who was secretly hoping that today's images downlinked from Spirit would show that the rover had magically popped out of the ground overnight. Of course, she didn't.

How to download the first imaging class: "Images Are Data"

Emily Lakdawalla • November 16, 2009

I finally prevailed in hosting the first in my series of classes on processing space images for amateurs this morning, while most people who were not working were probably watching the flawless launch of Space Shuttle Atlantis.

Rosetta Earth swingby successful

Emily Lakdawalla • November 13, 2009

Rosetta appears to have operated flawlessly as it streaked past Earth for its flyby early this morning. Here are a few more gems from the flyby.

LCROSS team: "Yes, we found water!"

Emily Lakdawalla • November 13, 2009

I just posted a story on the announcement today that LCROSS definitely found lots of water in the spectra from their October 9 impact.

Two new names in the solar system: Herse and Weywot

Emily Lakdawalla • November 12, 2009

Via the USGS I learned that Jupiter has passed a milestone of sorts, and now has fifty named satellites.

First space imaging class tomorrow, 10:30 a.m. Pacific / 18:30 UT

Emily Lakdawalla • November 12, 2009

The topic of the first class is: "Images Are Data." I'll go through how images actually represent scientific data, some very basic image processing stuff like histogram adjustment and what that does to the data, and what RGB color images are and how to compose them.
