DREAM Co-I Hurley presents the 2D distribution of lunar polar ice at the NLSI Seminar May 01, 2012

Dana Hurley is a DREAM co-I and planetary scientist at the Johns Hopkins University Applied Physics Lab. She studies volatiles on the Moon both in the sparse exosphere and in the lunar regolith. She investigates them as a Co-I on the LRO LAMP instrument and through computer modeling as part of the NASA Lunar Science Institute. She earned a Ph.D. and M.S. in Space Physics and Astronomy from Rice University and a B.A. in Physics from The Johns Hopkins University. The online recording of her 4/24 seminar entitled .2-D Distribution of Ice in Lunar Cold Traps. can be found at http://lunarscience.nasa.gov/event/nlsi-directors-seminar-dana-hurley-johns-hokins-university-applied-physics-lab/.

Vesta Cold, Dark, & Might Contain Ice: DREAM modelers apply their environmental analysis to a small(er) body Jan. 25, 2012

Though generally thought to be quite dry, roughly half of the giant asteroid Vesta is expected to be so cold and to receive so little sunlight that water ice could have survived there for billions of years, according to the first published models of Vesta's average global temperatures and illumination by the sun presented by Tim Stubbs of the DREAM team.

Solar Storms Could 'Sandblast' the Moon Dec. 6, 2011

Solar storms and associated Coronal Mass Ejections (CMEs) can significantly erode the lunar surface according to a new set of computer simulations by NASA scientists. In addition to removing a surprisingly large amount of material from the lunar surface, this could be a major method of atmospheric loss for planets like Mars that are unprotected by a global magnetic field.

The research is being led by Rosemary Killen at NASA's Goddard Space Flight Center, Greenbelt, Md., as part of the Dynamic Response of the Environment At the Moon (DREAM) team within the NASA Lunar Science Institute. See http://www.nasa.gov/topics/solarsystem/features/dream-cme.html.

Mystery of the Lunar Ionosphere Nov. 16, 2011

For 40 years, scientists have wondered how a Moon without air could have an electrically charged layer called an ionosphere. The answer? The moon, like Pig-Pen in Charlie Brown, is shrouded in a layer of dust. DREAM's Tim Stubbs describes this new surface -plasma-dust connection in a new Science@NASA web feature. See http://science.nasa.gov/science-news/science-at-nasa/2011/14nov_lunarionosphere/.

Lunar Swirls Workshop Without Walls Sept 1, 2011

Date: Wed, 2011-09-07 08:30 - 15:00

Swirls are among the most puzzling features on the surface of the Moon. The NLSI is hosting an informal one day Workshop without Walls on lunar swirls using NASA Lunar Science Institute (NLSI) remote communications tools. The swirls. bright, looping patterns are unlike anything seen in the solar system. The origin of the lunar swirls has been discussed for many years, but a universally accepted explanation for their formation remains elusive. Current space missions are returning new views of the lunar swirls, at resolutions and wavelengths never before considered. The workshop brings together magnetoplasma, geology/geochem, and remote sensing investigators for a shared discussion. For more information on the workshop see http://lunarscience.arc.nasa.gov/events/lunar-swirls-workshop-without-walls.

Moon Neutral Hydrogen Enigma Solved February 25, 2011

A nearly 40-year-old scientific conundrum has been solved with the discovery of how hydrogen escapes the lunar surface. Protons from the solar wind hit the moon and interact with the moon's surface to form hydrogen, but scientists hadn't known how they managed to zoom out again.

Waiter, There's Metal in My Moon Water February 17, 2011

Bring a filter if you plan on drinking water from the moon. Water ice recently discovered in dust at the bottom of a crater near the moon's south pole is accompanied by metallic elements like mercury, magnesium, calcium, and even a bit of silver. Now you can add sodium to the mix, according to Dr. Rosemary Killen of NASA's Goddard Space Flight Center in Greenbelt, Md

Apollo-era measurements yield a 2D map of the lunar dust exosphere January 28, 2011

DREAM members Dave Glenar, Tim Stubbs and Rich Vondrak, along with collaborator J. McCoy, reanalyzed measurements of excess light found in Apollo 15 coronal photographs taken near orbital sunset (surface sunrise), and attributed to forward scattering of sunlight by lunar exospheric dust grains. From this re-analysis, the team derived a new model of the extent of the lofted dust with applications for the LADEE mission.
