Dynamic Response of the Environments 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

DREAM2 study featured on the cover of JGR
February 11, 2016



Stunning visuals, showing a reflected ion fountain from the anomaly, graced the June 2015 journal cover

Results from a study led by DREAM2 postdoc Shahab Fatemi at UC Berkeley were published in Journal of Geophysical Research – Space Physics. The team modeled the solar wind plasma interaction with the Moons’ Gerasimovich magnetic anomaly using a state-of-the-art plasma simulation. The stunning visuals, showing a reflected ion fountain from the anomaly, graced the June 2015 journal cover. Congratulations to Shahab and his team!

DREAM2 co-I Misra wins NASA Early Opportunity Program Award
January 20, 2016



Howard University logo

A new Howard University and UMBC program will provide an early career pathway for underrepresented minority and women STEM students. The effort will focus on exposing six selected Howard University freshmen to NASA-centric research in Astrophysics, Solar System Exploration, Heliophysics and Earth Sciences throughout their undergraduate tenure. The six Howard University students will be stationed full-time at Goddard (some are anticipated to become part of DREAM2) during the three summers they are funded by this project. Dr. Misra is the PI of this new effort.

September 23, 2015



DREAM2's Mike Collier led a multi-institutional team including key expert partners from University of Iowa, Morehead State University, JPL, and George Washington University on the Hydrogen Albedo Lunar Orbiter (HALO) CubeSat mission concept. The concept was recently awarded development funding under NASA's SIMPLEx program. More details regarding HALO and other Cubesat missions funded under SIMPLEx can be found at:

SSERVI-Central website: The Need for Conductive Space Suits
September 14, 2015



DREAM2 studies are featured in a SSERVI-central web article on the need for conducting space suits. The DREAM2 team studies suggest a walking astronaut and moving rover are better grounded (in an electrical sense) to the plasma than to the regolith, and increasing conductivity of the space suit ensures a good current flow - a good electrical connection - from the plasma to the roving object.
