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 NEWS
DREAM2 team members Lora Bleacher, Tim Stubbs, Bill Farrell and Howard University Professor Prabhakar Misra met with students in the Department of Physics and Astronomy to advertise NASA Summer Internships (see http://intern.nasa.gov). After meeting with the students, they presented a seminar on 'Solar wind and its effect on exposed surfaces at the Moon and other airless bodies' at the weekly Department seminar series.
DREAM2 E/PO lead Lora Bleacher was a recent recipient of a 2015 Robert H. Goddard award for exceptional achievement for outreach. Lora has been leading the DREAM and DREAM2 education and communication efforts since 2008. She has lead our Lunar Extreme Workshops featuring high school student participation from around the country and is now leading DREAM2 undergraduate intern activity and DREAM2Explore teacher workshops. Congratulations!
We are very pleased to announce that our DREAM2 co-i and dear colleague Prof. Prabhakar Misra at Howard U. was just recently elected a Fellow of the American Physical Society (APS). Congratulations!

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:

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

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!
'Friends of Lunar Volatiles' Special Issue in Icarus is now releasedMay 27, 2015
A dedicated issue on the lunar volatile environment is now published in Icarus. DREAM2 co-I Dana Hurley was one of the editors. The special issue includes 18 papers on the latest studies of volatiles at the Moon, with applications to asteroids. See:

DREAM2 Co-I is part of Lunar IceCube mission for EM-1 Launch April 7, 2015
NASA has selected a lunar surface volatile cubesat mission called 'IceCube' lead by Morehead State University as one of HEOMD's NextSTEP program partnerships. The cubesat spacecraft will be launched to the Moon as part of the EM-1 mission onboard the SLS heavy-lift launch vehicle and will be subsequently deployed for lunar capture. DREAM2 Co-I Pamela Clark is a science lead and the mission with fly a GSFC-built IR system for identifying surface volatile content.
