The magnetic equator is far north of the planet’s geographic equator (the horizontal light gray line at 0° latitude), located about 300 miles north of the planet’s center.

I n August 2004, NASA’s MESSENGER mission — MErcury Surface, Space Envi- ronment, GEochemistry and Ranging — was launched on a seven- year-long journey to Mercury. And, on March 18, 2011, it made its historic entry into orbit around the planet.
Six PSI scientists, with differing areas of exper- tise, are on the MES- SENGER mission: Deb- orah Domingue Lorin, W i l l i a m F e l d m a n , Robert Gaskell, Eliza- beth Jensen, Catherine Johnson and Faith Vilas.
Onboard the spacecraft are seven scientific instruments that are providing researchers with new data on the planet’s geochemistry, geophysics, geologic history, atmosphere, and magnetic field en- vironment. With data from one of these instruments—the magne- tometer— Catherine Johnson, PSI Senior Scientist and MESSEN- (Continued next page) MESSENGER Scrutinizes Mercury by Alan Fischer and Chris Holmberg MESSENGER offers a new look at Mercury, the planet closest to the sun, with some surprises about its magnetic field. GER mission partici- pating scientist, is in- vestigating Mercury’s magnetic field and finding very interesting results. By characteriz- ing the magnetic field, MESSENGER will help answer the ques- tion of why the inner planets differ in their magnetic histories.
Some scientific views based on earlier Mer- cury flyby missions are being proven incorrect; one is about Mercury’s m a g n e t i c f i e l d . “Scientists thought Mer- cury's magnetic field was a miniature version of Earth's," said Sean Solomon of the Carne- gie Institution of Washington, the mission's principal investigator. "What we're seeing is, it is not."
In the 1970s, scientists learned from NASA’s Mariner 10 that Mercury had a significant magnetic field, as does Earth. (Venus and Mars do not.) Now, in 2011, the magnetometer instrument finds that the source of this magnetic field is not dead center in Mercury’s interior but 480 km (300 miles) north of the planet’s geographical equator. This is a surprising discovery, and it re- mains to be seen what this means about how Mercury’s field is generated. One consequence is that the magnetic field protecting This is an artist’s depiction of the MESSENGER spacecraft in orbit around the planet Mercury. Launched from Cape Canaveral on August 3, 2004, it returned to Earth for a gravity boost on August 2, 2005, then flew past Venus twice in October 2006 and June 2007. The spacecraft used the tug of Venus’ gravity to resize and rotate its trajectory closer to Mercury’s orbit. MESSENGER will be orbiting Mercury and collecting data until March 2012.

ith spacecraft observations, we can't always pick the perfect vantage point or place the sun exactly where we'd like it to be. But by using a computer graphics technique called raytracing, we can take spacecraft data and generate a new view of any location and with any lighting conditions.
For NASA's Dawn mission, which is currently in orbit around the asteroid Vesta, I've been using raytracing software called POV- Ray, together with photographs taken by Dawn, to better visualize the asteroid. To aid in the identification and mapping of geologic features, I have produced relief images of the topography, created animations of Vesta as it rotates, and generated simulated flyovers of its surface. The images at left and top right show ex- amples of how this software can be used to visu- alize the imaging and shape data together. They were made by combining im- age mosaics of Vesta's surface, produced by the German Aerospace Center (DLR), with a shape model of Vesta generated by PSI Senior Sci- entist Robert Gaskell.
The image at left is centered on the equa- tor, and shows a rela- tively smooth surface with prominent east- west grooves transi- tioning to a more heavily-cratered sur- face in the north.
The image at right shows a group of three prominent craters referred to as "The Snowman," as well as a mysterious dark spot towards the left of the image. The eleva- tions are exaggerated by a factor of approximately two in order to better highlight Vesta's surface features.
3,200 miles from Vesta on July 24, 2011, shows nearly a full hemisphere of the asteroid’s surface. “The Snowman” feature, at left, is one area that Dave O’Brien has cre- ated models of (see above) using Dawn’s framing camera photos and raytracing software.
The NASA Dawn mission will study Vesta for a year before de- parting for its second target, the dwarf planet Ceres, arriving in 2015. PSI is deeply involved in Dawn, with 12 scientists on the mission, and operates the Gamma Ray and Neutron Detector (GRaND), the instrument that will measure the elemental abun- dances of Vesta’s surface and constrain its mineralogical composi- tion. For more information about the Dawn mission, go to http:// www.nasa.gov/dawn .

different about what processes play a key role in the generation of Mercury’s magnetic field compared with those important to Earth’s magnetic field,” said Johnson. “The result may have im- portant implications for the internal dynamics of the planet and how the planet cools today.”
Johnson is also studying data from MESSENGER’s Mercury La- ser Altimeter, which is systematically mapping the topography of Mercury’s northern hemisphere. Major features on the planet – previously seen only at comparatively low resolution – are now in sharp focus. After more than two million laser-ranging observa- tions, the planet’s large-scale shape and profiles of geological features are being revealed in high detail. We now know that the north polar region of Mercury is a broad area of low elevations.
“We have in our solar system four experiments in how four Earth- like planets evolve once they form under slightly different condi- tions,” said Solomon, referring to Mercury, Venus, Earth and Mars, the four rocky planets of the inner solar system.
“What we’re learning is each of those experiments had an extraor- dinarily different outcome,” he said. “And one of those experi- ments we live on. So it behooves us, in a very general way, to understand how Earth-like planets form and evolve and operate.”
Other instruments on MESSENGER are producing interesting results as well. Measurements of the chemical composition of Mercury’s surface are providing important clues to the origin of the planet and its geological history. Maps of the planet’s topogra- phy and magnetic field are revealing new insights into Mercury’s interior dynamical processes. And scientists now know that bursts of energetic particles in Mercury’s magnetosphere are a continu- ing product of the interaction of Mercury’s magnetic field with solar wind.

Fall 2011 Japanese School Adapts PSI Crater Count Dating System, Wins Prize by William K. Hartmann I n August, 2010, I received an email from Yoshio Okamoto, a geosciences teacher at Tonnoji High School, affiliated with Osaka Kyoiku University, in Osaka, Japan. He was interested in using the crater chronometry system developed and used at PSI since the 1970s to estimate ages of planetary surfaces. The idea is simple: the more impact craters, the older the surface. Like many simple ideas in science, the im- plementation has been complex. We calibrated our system by using dates from rocks collected at Apollo moon landing sites, then translated the whole system to Mars. Starting in 2006, a strong confirmation of the system came, when cameras on Mars Global Surveyor and more recently Mars Reconnaissance Orbiter de- tected craters forming on Mars at a rate very close to our pre- dicted rate.
Okamoto stayed in touch, sending sample data and questions from the Japanese students and, as he noted, the system is ideal for classroom use. Teachers anywhere in the world can download scaled photographs of Martian geologic formations from many websites and distribute them to students. Students can measure diameters of craters in millimeters and convert to meters or kilometers on Mars. By measuring the area of the pho- tos, they can derive the number of craters per square km
in vari- ous diameters. Using data from our PSI web site (www.psi.edu/ research/isochrons/chron04a.html), teachers and students can plot Japanese high school students in Osaka use a measuring scale to record diameters of craters on Mars. their data on our “isochron diagram” (bottom of page 2 on PSI webpage) of the number of craters per square km versus crater diameter. Their results can then be compared to our “isochron” curves that show the predicted crater densities for various ages, such as 1 million years (My) or 1 billion years (Gy) and the stu- dent can read off the approximate age. The project is ideal not only for teaching simple geometric arithmetic, but also principles of statistics (the more craters that are counted, the less the scatter in the diagram), astronomy (the craters are caused by impacts of asteroids scattered through the solar system), and geology (younger geologic formations, such as new lava flows, are super- imposed on older surfaces, such as ancient river beds).
I received word in July that the students were off to present their results at the international “Super Science High School” confer- ence and competition among Japanese and Asian science stu- dents, held in Kobe, Japan. And then on August 21, I received an excited email from Okamoto that the students had won the Japanese Science and Technology Master prize—Silver medal—in the com- petition. As the stu- dents said, they have apparently taken crater counting to a higher level than any other high school in the world!
It’s exciting to see our work move from esoteric scientific jour- nals into distant classrooms, and we hope for additional interest from more teachers. We stand by to advise and assist.

P SI's Annual Retreat is always ener- gizing! It is great to have so many of our scientists in from around the coun- try and the world, interacting face to face, listening to presentations by our newest members, pushing forward ex- isting collaborations and starting up new ones.
We heard about asteroid populations, volcanism on the moon, planet formation in star clusters, Mer- cury's odd magnetic field, lunar paleomagnetism, probing mag- netic fields in the solar atmosphere, volatile atmospheres of satel- lites, microbes living in rock, and Saturn's rings.
We watched movies of avalanches in the Alps (what we do for science...), how to navigate on the moon from topography, con- struction of the Atsa Armrest Camera by students at The Citadel (with whom we did centrifuge training a few months ago), and plans for the study of Gale Crater by Curiosity (NASA Mars Sci- ence Lab rover) that launches for Mars this November.
This year we experimented with having posters. These proved very popular and useful for breakout discussions throughout the meeting. New additions kept popping up. We'll undoubtedly have more next year.
Our traditional banquet was also a great success (and delicious as usual, thanks to Janos!). A highlight of the evening was our Sponsored Projects Manager, Kelly Yoder, being surprised and stunned at being recognized for her 15 years of service at PSI. It has been a real pleasure, these past several years, to recognize the long tenure of so many of our staff and the great work they do.
This retreat was also marked by a PSiPad exchange. Since we only get together once a year, we always need to be working on improving our communications infrastructure to increase and promote interaction within our distributed Institute. The advent of the iPad 2 with a camera and capability for Skype and FaceTime was irresistible. I expect that we will get to the point, ultimately, where easy video communication is the norm.
Now we just need to get going on those flying cars! Mark V. Sykes October 2011
