Fourth MSL Landing Site Workshop: Day 2: Reports from Ryan Anderson

Emily Lakdawalla • September 30, 2010

I left the first day of the Fourth Mars Science Laboratory Landing Site Community Workshop on Monday just as they were getting in to the site-specific presentations.

Ryan Anderson • September 29, 2010

Today was jam-packed with interesting stuff about Mawrth, Holden, and Eberswalde! I took tons of notes, and I will try to use those to assemble a coherent picture of what was presented and discussed today.

The 4th MSL Landing Site Workshop: Day 2 - Eberswalde

Ryan Anderson • September 29, 2010

The final site of the four that we discussed yesterday was Eberswalde, which of course is interesting because of the big delta that is preserved in the western part of the crater.
