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 Scientists to further develop a lunar hydrogen exosphere CubeSat mission
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.

DREAM2 Interns win the John Mather Nobel Scholars AwardAugust 04, 2015

DREAM2 interns Anastasia Newheart of St. Mary’s College and Keenan Hunt-Stone of Howard University were each awarded the 2015 John Mather Nobel Scholars award for their science work during their summer internship. Congratulations!
See https://www.spacegrant.org/mather.

All the DREAM2 interns have been on the frontiers of space environmental science studies and will give their summer ending presentations on Thursday August 6 2015 at 1:00 pm, GSFC bldg. 34 room W305.

DREAM2’s Heidi Fuqua wins Outstanding Student Poster Award at ESFJuly 28, 2015

UCB Graduate Student and DREAM2 team member Heidi Fuqua won the Outstanding Poster presentation at the Exploration Science Forum. The poster was entitled ‘Isolating electromagnetic induction from the lunar interior measured with ARTEMIS’. Heidi’s advisor is Prof. Imke dePater and she did this latest work in collaboration with Greg Delory and Shahab Fatemi. Congratulations!

DREAM2 prepares for the SSERVI Exploration Science ForumJuly 14, 2015

NASA Exploration Science Forum

Next week, DREAM2 team scientist will be participating in the SSERVI Exploration Science Forum held at NASA Ames Research Center. DREAM2 scientists are leading over 15 presentations, and are chairing numerous sessions.

DREAM2Explore Educator WorkshopJune 22, 2015

The DREAM2 Team extends a warm welcome to the 25 teachers who will be joining us at Goddard from June 22-26 for the DREAM2Explore Workshop! This educator professional development workshop will focus on how our understanding of the Moon, asteroids, and the moons of Mars is growing and changing with new data from current and recent missions and modeling efforts led by the DREAM2 team. We'll also talk about NASA's plans for exploring asteroids in preparation for a human journey to Mars. We look forward to working with you this week!
