Alexandria, VA – Join Challenger Center for Space Science Education for a live interactive webcast, Wednesday, December 10th at 2:00pm ET with Dr. Barbara A. Cohen, a planetary scientist at NASA’s Marshall Space Flight Center. Dr. Cohen will take questions from participants and talk about lunar science and NASA’s Constellation Program that plans to send humans back to the Moon.

The first decades of the 21st century will be marked by major lunar science and exploration activities. The Moon is a witness to 4.5 billion years of solar system history, recording that history more completely and more clearly than any other planetary body. Dr. Cohen will discuss outstanding issues in lunar science today and the most intriguing scientific opportunities made possible by robotic and human exploration of our Moon.

The live interactive webcast is free and open to the public. It will be broadcast live at http://www.challenger.org.

Dr. Cohen works for the NASA Lunar Precursor Robotics Program on the Lunar Mapping and Modeling Project. She studies meteorites from the Moon, Mars and asteroids and has been to Antarctica twice to hunt for them. She also works on the Mars Exploration Rovers; Spirit and Opportunity. She supports NASA’s lunar flight projects as the co- chair of the Science Definition Team for NASA’s robotic lunar landers, nodes of the International Lunar Network, providing geophysical information about the Moon’s interior structure and composition.

Challenger Center for Space Science Education was founded in 1986 by the families of the astronauts of the space shuttle Challenger 51-L mission and is dedicated to the educational spirit of that mission. Challenger Learning Center programs at 50 centers continue the crew’s mission of engaging teachers and students in science, mathematics, engineering and technology.
