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…

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 constrain
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.
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. The
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 is
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 the
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 naturally
Saturn Helium Abundance: A Reanalysis of Voyager Measurements
Thermal emission spectra calculated using Voyager Jupiter radio occultation (RSS) temperature profiles rescaled to the Galileo probe value of the helium abundance do not agree with the spectra
Helium abundance in giant planets and the local interstellar medium
The sun and giant planets are generally thought to have the same helium abundance as that in the solar nebula from which they were formed 4.6 billion years ago. In contrast, the interstellar medium


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 =
Galileo Probe Mass Spectrometer experiment
The Galileo Probe Mass Spectrometer (GPMS) is a Probe instrument designed to measure the chemical and isotopic composition including vertical variations of the constituents in the atmosphere of
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.
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.
Goddard high-resolution spectrograph observations of the local interstellar medium and the deuterium/hydrogen ratio along the line of sight toward Capella
HST Goddard High-Resolution Spectrograph observations of the 1216, 2600, and 2800 A spectral regions are analyzed for the spectroscopic binary system Capella, obtained at orbital phase 0.26 with
The D/H ratio for Jupiter
Observations of Jupiter's spectrum near the R5(0) HD line at 6063.88 A are reported. A feature with an equivalent width of 0.065 + or - 0.021 mA is coincident with the expected line. This feature is

Tropospheric gas composition and cloud structure of the Jovian North Equatorial Belt
High spatial resolution Voyager infrared interferometer spectrometer spectra of the North Equatorial Belt (NEB) reveal longitudinal variability of 5-μm brightness temperatures of order 100°C. These
