All planetary materials sampled thus far vary in their relative abundance of the major isotope
of oxygen, 16O, such that it has not been possible to define a primordial solar system …

We describe the Genesis mission solar-wind sample collection period and the solar wind
conditions at the L1 point during this 2.3-year period. In order to relate the solar wind …

The application of secondary ion mass spectrometry (SIMS) has tremendous value for the
field of geobiology, representing a powerful tool for identifying the specific role of micro …

Abstract The Genesis Discovery mission returned solar matter in the form of the solar wind
with the goal of obtaining precise solar isotopic abundances (for the first time) and greatly …

Science results from the Genesis Mission illustrate the major advantages of sample return
missions.(i) Important results not otherwise obtainable except by analysis in terrestrial …

We present a description of the capabilities and performance of the NAval Ultra-Trace
Isotope Laboratory's Universal Spectrometer (NAUTILUS) at the US Naval Research …

We present the results of a coordinated NAUTILUS and NanoSIMS isotopic study of epsilon
(ε) phase metallic aggregates from the Oklo natural nuclear reactor zone (RZ) 13. We …

A commercial secondary ion mass spectrometer (SIMS) was coupled to a±300 kV single-
stage accelerator mass spectrometer (SSAMS). Positive secondary ions generated with the …

We have measured the isotopic composition and fluence of solar‐wind nitrogen in a
diamond‐like‐carbon collector from the Genesis B/C array. The B and C collector arrays on …

The NASA Genesis solar-wind (SW) mission was the first to return to Earth from beyond the
Moon, delivering SW ions collected in high-purity substrates (eg, Si wafers) over 887 days …
