Dynamic Response of the Environment at Asteroids, the Moon, and moons of Mars

Goddard's DREAM2 Center for Space Environments

DREAM2 incorporates over 30 science investigators from over 10 academic Institutions to study the space environment at exploration targets. DREAM2 is:

  • A theory, modeling, data analysis research team examining the space environment at airless bodies
  • Answering "How does the space environment affect volatiles, exospheres, plasmas, surface micro-structure, and visiting human systems at any exposed rocky body?"
  • Emphasizing the dynamic solar storms and human interactions at airless bodies.
  • A modeling center that maintains, advances, and integrates state-of-the-art neutral, plasma, radiation, and surface interaction models
  • Sponsored by Solar System Exploration Research Institute (SSERVI) Headquartered out of Ames Research Center Moffett Field CA, 94035



SSERVI's Exploration Science Forum Agenda Available Online       July 15,2014

The ESF agenda is now available at:


Lots of great talks and posters to be presented! All the action is next week (7/21-23) at NASA/Ames.

Redistribution of lunar polar water to mid-latitudes                      January 10, 2014

In December 2013, DREAM scientists published a study in Planetary and Space Science on the possible transport of volatiles from the floor of lunar polar craters to the topside surface at mid-latitudes. Energetic processes like ion sputtering and impact vaporization were shown to eject/release polar water molecules residing within cold trapped regions, possibly with sufficient velocity to allow their redistribution to mid-latitudes. The team then considered the possibility that these polar-ejected molecules contributed to the 3 micron IR absorption featured observed by Chandrayaan-1, Cassini, and EPOXI.
