Analysing Rock Samples for the Mars Lander

In the near future NASA intends to explore various regions of our solar system using robotic devices such as rovers, spacecraft, airplanes, and/or balloons. Such platforms will carry imaging devices, and a variety of analytical instruments intended to evaluate the chemical and mineralogical nature of the environment(s) that they encounter. The imaging and/or spectroscopic devices will acquire t...

Development of rapid and precise Pb isotope analytical techniques using MC-ICP-MS and new results for GSJ rock reference samples

A rapid and precise routine Pb isotope analytical technique for rock samples was developed using multiple collector inductively coupled plasma mass spectrometry (MC-ICP-MS). The mass discrimination of the Pb isotope ratios was corrected with the 205Tl/203Tl ratio of a Tl isotope reference material (NIST SRM 997) added to samples. The optimization of the analytical parameters and the minimizatio...

Evaluating the Effects of Radio-Frequency Treatment on Rock Samples: Implications for Rock Comminution

Cross Contamination of Martian Rock Samples

This paper presents the results of theoretical analyses conducted to investigate potential of various particle removal techniques. The purpose is to limit the extent of cross contamination caused by the small particles generated through in situ handling and processing of the simulated Martian rock. Since the same hardware would be used to process several rocks, the cross contamination is define...

Comment on: Curling rock dynamics — The motion of a curling rock: inertial vs. noninertial reference frames

We examine the approach used and the results presented in a recent publication (Can. J. Phys. 76, 295 (1998)) in which (i) a noninertial reference frame is used to examine the motion of a curling rock, and (ii) the lateral motion of a curling rock is attributed to left–right asymmetry in the force acting on the rock. We point out the important differences between describing the motion in an ine...
