CheMin: (Chemistry & Mineralogy)
An important science goal of the MSL mission is to identify and characterize past or present habitable environments as recorded in sediments and rocks. CheMin is a definitive mineralogy instrument that will identify and quantify the minerals present in rocks and soil delivered to it by the Sample Acquisition, Sample Processing and Handling (SA/SPaH) system. By determining the minerals in rocks and soils, CheMin will assess the involvement of water in their formation, deposition, or alteration. In addition, CheMin data will be useful in the search for potential mineral biosignatures (or any phenomenon produced by life), energy sources for life or indicators of past habitable environments. CheMin can identify and quantify minerals in complex natural samples such as basalts, multicomponent evaporite systems (a natural mineral deposit left after the evaporation of a body of water), and soils.
David Blake, of NASA Ames Research Center, began working 21 years ago on a compact X-ray diffraction instrument for use in planetary missions. His work with colleagues has resulted in commercial portable instruments for use in geological field work on Earth, as well as the CheMin instrument. The spinoff instruments have found innovative applications in screening for counterfeit pharmaceuticals in developing nations and analyzing archaeological finds.
"You get a series of spacings and intensities for each mineral," Blake said. "It's more than a fingerprint because it not only provides definitive identification, but we know the reason for each pattern, right down to the atomic level."
Lunar Reconnaissance Orbiter (LRO): Leading NASA's Way Back to the Moon
Launched on June 18, 2009, LCROSS traveled to the Moon as a co-manifested payload aboard the launch vehicle for the Lunar Reconnaissance Orbiter (LRO). LRO is designed to map the lunar surface and characterize landing sites for future missions.
Lunar Crater Observation and Sensing Satellite (LCROSS): NASA's Mission to Search for Water on the Moon
The Mission Objectives of the Lunar Crater Observation and Sensing Satellite (LCROSS) included confirming the presence or absence of water ice in a permanently shadowed crater at the Moon's South Pole. The identification of water is very important to the future of human activities on the Moon. LCROSS excavated the permanently dark floor of Cabeus Crater with two heavy impactors in 2009 to test the theory that ancient ice lies buried there. The impact ejected material from the crater's surface to create a plume that specialized instruments analyzed for the presence of water (ice and vapor), hydrocarbons and hydrated materials.
LCROSS also provided technologies and modular, reconfigurable subsystems that can be used to support future mission architectures.
Ames Research Center (ARC) managed the mission, conducted mission operations, and developed the payload instruments, while Northrop Grumman designed and built the spacecraft for this innovative mission. Ames mission scientists spearheaded the data analysis. This fast-paced, low-cost, mission leveraged some existing NASA systems, Northrop-Grumman spacecraft expertise, and Ames' Lunar Prospector experience.

NASA's first mission capable of finding Earth-size planets around other stars.
|At left, Division Scientist Darlene Lim sampling water from a lake on Devon Island, Nunavut. The myriad of lakes and ponds in the Canadian High Arctic are important to understanding past, present and future environmental conditions. These aquatic systems are under-going ecological change in response to recent global warming. Follow this link to see images Darlene took in the Canadian High Arctic.|
|Nathalie Cabrol reports on her exciting and successful field work from the mountains in South America. 'We stayed 5 days and 4 nights in the mountain mostly around 5,916 m. While this was physically tough, the reward was immense as we successfully completed all of our science, including our two planned scuba dives in the summit lake of the volcano....'

|Louis Allamandola has won three great honors. He was elected a fellow by two prestigious science organizations, the American Association for the Advancement of Science and the American Physical Society. He was also recognized with The Presidential Rank Award, one of the highest honors a civilian can receive. He has been recognized for 'seminal contributions in astrochemistry that have forever revolutionized our understanding of interstellar molecules, interstellar ices, and the chemical physics of the interstellar medium.'

During the meeting of the Division of Planetary Science (DPS) in Pasadena our own Dale Cruikshank was awarded the highly prestigious Gerard P. Kuiper Prize in recognition of his pioneering work in the application of infrared spectroscopy to solar system bodies, his development of laboratory techniques that have become tools for interpreting observations, and his leadership in the design of instruments for remote sensing observations from deep space planetary exploration probes.
