The composition of the jovian atmosphere from 0.5 to 21 bars along the descent trajectory was determined by a quadrupole mass spectrometer on the Galileo probe. The mixing ratio of He (helium) to H2 (hydrogen), 0.156, is close to the solar ratio. The abundances of methane, water, argon, neon, and hydrogen sulfide were measured; krypton and xenon were detected. As measured in the jovian atmosphere, the amount of carbon is 2.9 times the solar abundance relative to H2, the amount of sulfur is… Expand

The Galileo Probe entered the atmosphere of Jupiter on December 7, 1995. Measurements of the chemical and isotopic composition of the Jovian atmosphere were obtained by the mass spectrometer duringExpand
Noble gas abundance and isotope ratios in the atmosphere of Jupiter from the Galileo Probe Mass Spectrometer
The Galileo Probe Mass Spectrometer provided the first data on the noble gas mixing and isotope ratios in the Jovian atmosphere. These measurements and the comparison with solar values constrainExpand
The composition of the Jovian atmosphere as determined by the Galileo probe mass spectrometer.
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. Expand

Updated Galileo probe mass spectrometer measurements of carbon, oxygen, nitrogen, and sulfur on Jupiter
The in situ measurements of the Galileo Probe Mass Spectrometer (GPMS) were expected to constrain the abundances of the cloudforming condensible volatile gases: H2O, H2S, and NH3. However, since theExpand
Abundances of Hydrogen and Helium Isotopes in Jupiter
Abundances of hydrogen and helium isotopes in Jupiter and other giant planets can answer important questions on the origin of elements in the solar system and the nature of processes in the sun. TheExpand
Oxygen in the Sun
We review elemental and isotopic abundances of oxygen in the Sun and their implications for solar physics and Solar System formation. The oxygen content of the Sun, expressed as the O/H atom ratio,Expand
The deuterium abundance in Jupiter and Saturn from ISO-SWS observations
Observations with the Short Wavelength Spectrometer (SWS) onboard the Infrared Space Observatory (ISO) are used to determine the D/H ratio in Jupiter's and Saturn's atmospheres. The D/H ratio isExpand
Strange Xenon Isotope Ratios in Jupiter
In January 1998, the public release of the data collected by the Galileo space probe’s mass spectrometer on its descent into Jupiter’s atmosphere allowed scientists a glance at the composition of theExpand
Abundances of hydrogen and helium isotopes in the Protosolar Cloud
Abstract For our understanding of the origin and evolution of baryonic matter in the Universe, the Protosolar Cloud (PSC) is of unique importance in two ways: 1) Up to now, many of the naturallyExpand


The helium abundance of Saturn from Voyager measurements
Voyager radio-occultation and IR spectroscopy measurements are combined to infer an He mole fraction in the upper troposphere of Uranus of 0.152 + or - 0.033; the corresponding mass fraction is Y =Expand

The Helium Mass Fraction in Jupiter's Atmosphere
Measurements of the helium abundance in the atmosphere of Jupiter provided by the NASA Galileo probe indicate that separation of helium from hydrogen in Jupiter's interior is only in its early stages. Expand
Comets, impacts, and atmospheres.
A mixture of three basic types of comets appears capable of accounting for the observed volatile inventories on Venus, Earth, and Mars, with the caveat that impact erosion is necessary to explain the present condition of the martian atmosphere. Expand
Ammonia vertical density profiles in Jupiter and Saturn from their radioelectric and infrared emissivities
Abstract The distribution of ammonia with height in the atmospheres of Jupiter and Saturn has been determined by inversion of microwave thermal spectra and from spectroscopic measurements of theExpand
