Journal ArticleDOI
The abundances of constituents of Titan's atmosphere from the GCMS instrument on the Huygens probe
Hasso B. Niemann,Sushil K. Atreya,Siegfried Bauer,G. R. Carignan,J. E. Demick,R. L. Frost,D. Gautier,J. A. Haberman,D. N. Harpold,Donald M. Hunten,G. Israel,Jonathan I. Lunine,Wayne Kasprzak,Tobias Owen,Michael B. Paulkovich,François Raulin,E. Raaen,S. Way +17 more
TL;DR: Direct atmospheric measurements from the Gas Chromatograph Mass Spectrometer (GCMS), including altitude profiles of the constituents, isotopic ratios and trace species (including organic compounds), were reported, confirming the primary constituents were confirmed to be nitrogen and methane.
Journal ArticleDOI
Smoke and Dust Particles of Meteoric Origin in the Mesosphere and Stratosphere
TL;DR: In this paper, a height profile of ablated mass from meteors is calculated, assuming an incoming mass of 10 to the -16th g/sq cm/s (44 metric tons per day) and the velocity distribution of Southworth and Sekanina, which has a mean of 14.5 km/s.
Journal ArticleDOI
Mass fractionation in hydrodynamic escape
TL;DR: In this article, it was shown that mass fractionation occurs during the course of hydrodynamic escape of gases from the atmosphere of an inner planet, and that the resultant fractionation as a function of mass yields a linear or concave downward plot in a graph of remaining inventory against atomic mass.
Journal ArticleDOI
The composition of the Jovian atmosphere as determined by the Galileo probe mass spectrometer.
H. B. Niemann,H. B. Niemann,Sushil K. Atreya,G. R. Carignan,T. M. Donahue,J. A. Haberman,D. N. Harpold,Richard E. Hartle,Donald M. Hunten,Wayne Kasprzak,Paul R. Mahaffy,T. C. Owen,S. H. Way +12 more
TL;DR: Analysis of some of the constituents detected suggests that icy planetesimals made significant contributions to the volatile inventory, and (4) a moderate decrease in D/H but no detectable change in (D + 3He)/H in this part of the galaxy during the past 4.6 Gyr.
Journal ArticleDOI
Understanding the Lunar Surface and Space-Moon Interactions
Paul G. Lucey,Randy L. Korotev,Jeffrey J. Gillis,Lawrence A. Taylor,David J. Lawrence,Bruce A. Campbell,R. C. Elphic,Bill Feldman,Lon L. Hood,Donald M. Hunten,Michael Mendillo,Sarah K. Noble,James J. Papike,Robert C. Reedy,S. L. Lawson,Thomas H. Prettyman,Olivier Gasnault,Sylvestre Maurice +17 more
TL;DR: The surface of the Moon is a critical boundary that shapes our understanding of the entire Moon as a whole as discussed by the authors, and it is the lower boundary layer of the tenuous lunar atmosphere and constitutes both a source and a sink for atmospheric gases.
