Abstract
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 laboratories: the isotopic compositions of O, N, and noble gases differ in the Sun from other inner solar system objects. The N isotopic composition is the same as that of Jupiter. Genesis has resolved discrepancies in the noble gas data from solar wind implanted in lunar soils. (ii) The most advanced analytical instruments have been applied to Genesis samples, including some developed specifically for the mission. (iii) The N isotope result has been replicated with four different instruments.

Published online before print May 9, 2011. I gratefully acknowledge the work of over 100 scientists representing the Genesis Science Team, whose work has been summarized. A spacecraft mission is only possible with the contributions of hundreds of people. The Genesis Mission was executed by the Jet Propulsion Lab (management, payload design and fabrication, mission operations), Lockheed Martin Astronautics (spacecraft, spacecraft operations), Los Alamos National Lab (concentrator, regime monitors), NASA Johnson Space Center (payload integration), and the Mid-Continent Educational Lab (education and public outreach). Besides the Discovery Program, the Genesis Science Team acknowledges support from the NASA Sample Return Laboratory Instrument Definition Program (SRLIDAP) and Laboratory Analysis of Returned Samples (LARS) programs. Author contributions: D.S.B. and G.S.T. designed research; D.S.B. and G.S.T. performed research; G.S.T. contributed new reagents/analytic tools; D.S.B. and G.S.T. analyzed data; and D.S.B. and G.S.T. wrote the paper.Attached Files
