The briefing will take place in the NASA Headquarters auditorium located at 300 E Street, S.W. in Washington and carried live on NASA Television and www.nasa.gov. The agency last week announced the spacecraft's mission may be at its end. Mars Global Surveyor has served the longest and been the most productive of any spacecraft ever sent to the red planet. Data gathered from the mission will continue to be analyzed by scientists. Panelists include: - Michael Meyer -- Lead Scientist, Mars Exploration Program, NASA Headquarters, Washington - Michael Malin -- President and Chief Scientist, Malin Space Science Systems, San Diego, Calif. - Kenneth Edgett -- Scientist, Malin Space Science Systems - Philip Christensen -- Professor, Arizona State University, Tempe, Ariz. |

I see that Jim Bell had a nit to pick. A little off-topic, but its worth noting that light-toned units on Mars often, but not always, exhibit different color properties than the surrounding terrains. Typically, they're redder. This has been a research interest of mine for a while, and presents an excuse to show a few pretty pictures. Here are some THEMIS VIS examples from Aram, Aureum, and Iani Chaos, where the lighter-toned units are also "redder"--a quantity that is shown in the lower set of images as THEMIS VIS 540 nm band depth images. Anyway, these deposits are quite different from the gully light-toned material, but if that material has similar color properties to the above images, it would be indicative of an increased Fe3+ content. |

Is this figure from the paper "Evidence for aqueous deposition of hematite and sulfate-rich light-toned layered deposits in Aureum and Iani Chaos," which you and A. Deanne Rogers have submitted to JGR-Planets? |
