DREAM2 co-I Mike Zimmerman at APL recently lead a simulation study of lunar surface dust regolith charging in plasma and in sunlight – showing the development of inhomogeneous grain charging and the formation of large E-fields between grains. Zimmerman’s research team included members of SSERVI’s DREAM2, IMPACT, and VOTICES teams. The paper was recently accepted and is now in press in Journal of Geophysical Research.

NASA’s Goddard Space Flight Center

DREAM2 is hosting a free workshop for grade 6–9 science teachers. Participants will learn how our understanding of the Moon, asteroids, and the moons of Mars is growing and changing with new data and models from current and recent planetary missions and the work of the DREAM2 team. Teachers will meet with NASA scientists that study the dynamic environments surrounding these rocky objects. All pre-service and in-service grade 6–9 science teachers are encouraged to apply! More information about the workshop and a link to the applications are available here:

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!

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.

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.
