All news conferences are in the press briefing room Moscone West, level 2, room 2012. Reporters may call NASA's Jet Propulsion Laboratory media relations at: (818) 354-5011 for phone numbers to listen and ask questions from remote locations.

News Conference: Mars Express Reveals Red Planet's Past, Present
Time: Mon. Dec. 5, 3 p.m. EST (12 p.m. PST)
Related Session:: P13C

The Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS), which is on the European Space Agency's Mars Express orbiter, is the first radar instrument looking below the surface of Mars. The instrument was designed to search for subsurface layers containing frozen or liquid water and to examine the upper region of Mars' atmosphere. Results from the radar and from other instruments on Mars Express are adding to a wealth of new information about past and present conditions on Mars.

News Conference: Mars Rovers Celebrate First Martian Anniversary
Time: Mon. Dec. 5, 4 p.m. EST (1 p.m. PST)
Related Sessions:: P11D, P11E, P12A

In early December, NASA's long-lived rovers, Spirit and Opportunity, are completing a full Martian year of work on the surface of Mars. The adventure continues more than 22 months into what was originally planned as a three-month mission. Recently, Opportunity reached exposures of water-altered bedrock with intriguing differences from the stack of layers it examined inside a crater last year. Spirit is hurrying downhill to investigate a platform-like feature before Martian winter sets in, but keeps finding surprises along the way. Researchers are still struggling to decipher the ancient environmental history of Spirit's vicinity from an increasingly diverse set of clues.

News Conference: Discovering Space Weather "Cold Fronts"
Time: Mon. Dec. 5, 7 p.m. EST (4 p.m. PST)
Related Session:: SA11A
For more information visit:
Scientists have identified large, global-scale disturbances that form in Earth's upper atmosphere during space storms that disrupt the signals we use to communicate, navigate and monitor our borders. Although these disturbances had previously been observed locally and sporadically, a new view combining ground and space observations provides an unprecedented global perspective that allows scientists to see the structures in their entirety and understand how and why they evolve with time. This global view has been accomplished with measurements developed and operated for NASA and the National Science Foundation.

News Conference: Ozone Hole: Prospects for Recovery
Time: Tues. Dec. 6, 12 p.m. EST (9 a.m. PST)
Related Sessions:: A13D
For more information visit:
Twenty years after the discovery of the Antarctic ozone hole, it now appears that its recovery may take longer than predicted. This briefing takes a look at ozone depletion over both poles and presents new results on the surprisingly high levels of ozone-destroying halocarbons still being released in the United States and Canada. NASA scientists provide an overview of the 2005 ozone layer record and report on new satellite observations of the high levels of ozone-destroying chlorine in the stratosphere over both poles that are declining very slowly. There will also be new projections from NOAA of when the ozone hole may fully recover and some surprising differences between how recovery will occur in the Arctic versus the Antarctic.

News Conference: Cassini's Marathon Tour of Saturn's Icy Moons
Time: Tues. Dec. 6, 3 p.m. EST (12 p.m. PST)
Related Session:: P11B, P21F, P22A and P32A
For more information visit:
The remarkable Cassini mission has captured new views and information on young, old and oddball moons during the first year of a whirlwind tour of the Saturn system. Scientists will present the latest findings and images from Cassini, including breathtaking views and a deluge of data from these icy orbs during more than a dozen targeted flybys. Among the discoveries is the moon Enceladus has an atmosphere, which appears to be contributing particles to Saturn’s massive E-ring. Another discovery includes a long, narrow ridge that lies almost exactly on the equator of the moon Iapetus. In places, the ridge is approximately three times the height of Mount Everest.

News Conference: Earth Science Theatre for Reporters: A Tour of the Cryosphere: Earth's Frozen Assets
Time: Tues. Dec. 6 and Thurs. Dec. 8 at 5 p.m. EST (2 p.m. PST)
Related Sessions:: C33A, C34A, C51B
For more information visit:
From the shrinking Arctic sea ice to retreating glaciers and collapsing Antarctic ice shelves, the cryosphere is an important and ongoing news story. NASA satellites captured these snow and ice changes worldwide to help scientists figure out what is happening. A unique global view of all of these scientific issues is presented in the new NASA video, which is being released at this meeting. The video tour takes you around the world to see what is happening through state-of-the-art animations of the latest satellite data. NASA scientist Waleed Abdalati and television producer Michael Starobin will answer questions about new cryosphere research and how the visualizations can be used to illustrate the science.

News Conference: New Results from NASA's Gravity Recovery and Climate Experiment (GRACE) Mission
Time: Tues. Dec. 6, 6 p.m. EST (3 p.m. PST)
Related Session:: G22A, G23A, G24A, G33A, G33B, G33C, H11G, IN 22A, SA41A
For more information visit:
Three and a half years into its primary mission to map Earth's changing gravity field with unsurpassed precision, NASA's Gravity Recovery and Climate Experiment (GRACE) is changing our views on gravity and how variability in Earth's mass affects the balance of Earth's natural systems. This briefing presents an overview of mission status and research efforts; detailing three areas: 1) GRACE observations of how the Great Sumatra earthquake of Dec. 26, 2004, affected Earth's gravity field and how that data may shed new light on earthquake physics and mechanisms; 2) A recap of ice mass change measurements for Greenland, the only direct measurements currently available of ice mass; and 3) An overview of results to date on the seasonal transport variability of the Antarctic Circumpolar Current, the strongest current system in the world, which links the Atlantic, Indian and Pacific basins and significantly influences global climate.

News Conference: Calipso and Cloudsat Science Writer's Workshop
Time: Wed. Dec. 7 at 5 p.m. EST (2 p.m. PST)
Related Sessions:: A23A, ED31D
For more information visit:

NASA is launching two satellites that will answer questions about how clouds and aerosols form, evolve and affect water supply, climate, weather and air quality. This workshop will feature scientists who will provide the background science of clouds and aerosols with a new, 3-D perspective.

News Conference: Glaciers Retreat in Alaska and Greenland and Beyond
Time: Wed. Dec. 7 at 6 p.m. EST (3 p.m. PST)
Related Sessions:: C41A
Changes to glaciers and ice sheets have become an almost worldwide phenomenon. Such changes can be particularly large where the ice from glaciers or ice sheets hit the sea. This session emphasizes these large changes in glaciers or ice sheets in Alaska, Greenland and the Antarctica. The ice break-up in these cases far exceeds what is possible due to surface melting alone. This raises questions about the stability of glaciers and ice sheets.

News Conference: Solar Terrestrial Relations Observatory Science Writer's Workshop
Time: Thurs. Dec. 8 at 1 p.m. EST (10 a.m. PST)
Related Sessions:: ED31D, SH11B, SH23B
For more information visit:
When the Solar Terrestrial Relations Observatory (STEREO) launches in Spring 2006, scientists expect to gain a better understanding of space weather and improve warning time for the massive solar storms that could harm astronauts, satellites, communication systems and electric power grids. The two STEREO spacecraft will image the sun and its explosions in high definition 3-D for the first time. Our current two-dimensional view makes it hard to predict which direction the events are heading. In this workshop, news reporters will learn all about space weather and STEREO's 3-D mission and be able to ask the experts questions on the latest advances in the field.

News Conference: Aura Satellite Track's Earth's Air Quality
Time: Thurs. Dec. 8 at 2 p.m. EST (11 a.m. PST)
Related Sessions:: A13D, A41A, A41B, A43E, A44C, A53C, A54B
For more information visit:
Local and regional air pollution and their sources can now be closely watched from space. Researchers using the latest data from NASA's Aura satellite report on detailed tracking of important pollutants such as ozone and nitrogen dioxide. In addition, the first global observations of ice in clouds by Aura are shown to be important in reducing uncertainties in predictions of future climate change. The role of these new tools for air quality and climate forecasts will be discussed.
