Welcome
Scientists at DTM bring the perspective of several disciplines to broad
questions about nature. DTM's name comes from its original role to
chart the Earth's magnetic field. This goal was largely accomplished by
1929. Since then, DTM has evolved to reflect the growing multi-
disciplinary nature of the Earth, planetary, and astronomical sciences.
Today, the historic goal remains-to understand the physical Earth and
the universe that is our home.

The MESSENGER Mission to Mercury completed a critical deep-space maneuver yesterday—155 million miles (240 million kilometers) from Earth—successfully firing its large bi-propellant engine to change the probe’s trajectory and target it for its first flyby of Mercury on January 14, 2008.
The maneuver was executed in two parts from the MESSENGER Mission Operations Center at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md. At 6 p.m. EDT, the probe fired its large main engine for just over five minutes, using about 70 kilograms (154 pounds) of propellant to change its velocity by 226 meters per second, or just over 505 miles per hour.

DTM Visiting Investigator and former CASE (Carnegie Academy for Science Education) Director Inés Cifuentes is the recipient of the 2007 Hispanic Heritage Award for Math and Science. Instituted by the White House in 1987, the Hispanic Heritage Awards are the most prestigious Hispanic honors in the United States. Cifuentes is recognized for her role in creating CASE. The award citation notes that “during the ten years she directed CASE, more than 1,000 teachers were trained in science, mathematics, and technology, and a group of fifty talented CASE mentor teachers were nurtured.” Now the Manager of Education at AGU, Cifuentes has also been awarded the National Hispanic Scientist of the Year Award from the Museum of Science and Industry in Tampa, FL. For more information, see the award citation.

MESSENGER Fellow Natalia Gómez Pérez joined DTM on 1 October, following the defense of her Ph.D. at the University of Alberta last month. Gómez Pérez’s thesis involved numerical studies of magnetic dynamos in planets, including terrestrial planets, ice giants, and gas giants. By mean of numerical simulations, she showed that the intensity and geometry of planetary magnetic fields are determined by the internal structure and the physical properties of the dynamo-generating fluid.
