Introduction: Asteroidal fragments in lunar breccias and soils are critical to an understanding of the nature of the major impactors of the Moon. Observing FeNi metal is typically the simplest way for identifying asteroidal fragments. Schreibersite [(Fe,Ni) 3 P] in FeNi metal is a clear indicator of asteroidal contamination , although this was validated only after the realization that schreiber...

Purpose: The work reported here responds to the need to provide the Constellation Program Office Lunar Surface Systems Project with science requirements for lunar surface system architecture and metrics for lunar surface system operations, and to do so in a way that addresses lunar science goals, as most recently stated by the Lunar Exploration Working Group (LEAG) [1]. In response, the Surface...

The lure of the Moon is strong — and humans are once again responding to the challenge. One promising, near-term scenario is to land a pair of rovers on the Moon, and to engage in a multiyear, 1000 kilometer traverse of historic sights, including Apollo 11, Surveyor 5, Ranger 8, Apollo 17 and Lunokhod 2 [2]. In this scenario, one of the rovers would be driven, returning continuous live video, w...

Fault sealing is one of the key factors controlling hydrocarbon accumulations and trap volumetrics and can be a significant influence on reservoir performance during production. Fault seal is, therefore, a major exploration and production uncertainty. We introduce a systematic framework in which the geologic risk of faults trapping hydrocarbons may be assessed. A fault may seal if deformation p...

BACKGROUND The Low Flow Wizard (LFW) provides real-time guidance for user optimization of fresh gas flow (FGF) settings during general inhaled anesthesia. The LFW can continuously inform users whether it determines their FGF to be too little, efficient, or too much, and its color-coded recommendations respond in real time to changes in FGF performed by users. Our study objective was to determin...

Lunar meteorites provide a wider sampling of the lunar surface compared to the samples collected during the Apollo and Luna Missions. Apatite is the main hydroxyl-bearing (proxy for water) mineral in lunar samples, especially in basaltic rocks. Apatite is also amenable to in-situ U-Pb age dating studies. The ages of lunar basaltic meteorites also span over a larger range compared to basaltic sa...
