Kepler Mission Design, Realized Photometric Performance, and Early Science
The Kepler Mission, launched on 2009 March 6, was designed with the explicit capability to detect Earth-size planets in the habitable zone of solar-like stars using the transit photometry method.… Expand
The abundances of constituents of Titan's atmosphere from the GCMS instrument on the Huygens probe
Saturn's largest moon, Titan, remains an enigma, explored only by remote sensing from Earth, and by the Voyager and Cassini spacecraft. The most puzzling aspects include the origin of the molecular… Expand
The composition of the Jovian atmosphere as determined by the Galileo probe mass spectrometer.

- Journal of geophysical research
- 25 September 1998
The Galileo probe mass spectrometer determined the composition of the Jovian atmosphere for species with masses between 2 and 150 amu from 0.5 to 21.1 bars. This paper presents the results of… Expand
Composition of Titan's lower atmosphere and simple surface volatiles as measured by the Cassini‐Huygens probe gas chromatograph mass spectrometer experiment
 The Cassini-Huygens probe gas chromatograph mass spectrometer (GCMS) determined the composition of the Titan atmosphere from ∼140 km altitude to the surface. After landing, it returned… Expand
Detection of methane in the martian atmosphere: evidence for life?
Using the Fourier Transform Spectrometer at the Canada–France–Hawaii Telescope, we observed a spectrum of Mars at the P-branch of the strongest CH4 band at 3.3 µm with resolving power of 180,000 for… Expand
A comparison of the atmospheres of Jupiter and Saturn: deep atmospheric composition, cloud structure, vertical mixing, and origin.
- S. Atreya, M. Wong, +5 authors T. Encrenaz
- Medicine, Physics
- Planetary and space science
- 1 October 1999
We present our current understanding of the composition, vertical mixing, cloud structure and the origin of the atmospheres of Jupiter and Saturn. Available observations point to a much more vigorous… Expand
67P/Churyumov-Gerasimenko, a Jupiter family comet with a high D/H ratio
The provenance of water and organic compounds on Earth and other terrestrial planets has been discussed for a long time without reaching a consensus. One of the best means to distinguish between… Expand
Deuterium in comet C/1995 O1 (Hale-Bopp): detection of DCN.
Deuterated hydrogen cyanide (DCN) was detected in a comet, C/1995 O1 (Hale-Bopp), with the use of the James Clerk Maxwell Telescope on Mauna Kea, Hawaii. The inferred deuterium/hydrogen (D/H) ratio… Expand
Surface Ices and the Atmospheric Composition of Pluto
Observations of the 1.4- to 2.4-micrometer spectrum of Pluto reveal absorptions of carbon monoxide and nitrogen ices and confirm the presence of solid methane. Frozen nitrogen is more abundant than… Expand
Molecular nitrogen in comet 67P/Churyumov-Gerasimenko indicates a low formation temperature
Making comets in the cold The speciation of nitrogen compounds in comets can tell us about their history. Comets are some of the most ancient bodies in the solar system and should contain the… Expand
