Allan Hills (ALH) 84001 is the most recently recognized member of a suite of meteorites--the SNCs--that almost certainly originated on Mars. Several factors distinguish ALH84001 from the other SNC meteorites. Preliminary studies suggest that it may be older than other martian meteorites. Moreover, it contains abundant, zoned domains of(More)

Introduction: We have made new surveys of thin sections of the martian meteorite Nakhla by petrographic microscope, laser Raman spectroscopy, NanoSims Ion Microprobe, and stepped combustion static mass spectroscopy. We have also applied a computer technique that produces three-dimensional anaglyphs from a series of down-through-focus images in a standard(More)
In May 2014, the Rosetta spacecraft is scheduled to rendezvous with the comet Churyumov-Gerasimenko ('67P'). One of the instruments on board the 'Lander' which will descend on to the surface of the comet is a miniaturised GC/MS system that incorporates an ion trap mass spectrometer, specially developed for isotope ratio analysis. This article describes the(More)
[1] This paper describes selection and characterization of the landing site for the Mars 2004 Beagle 2 mission. The site is within Isidis Planitia between 10°–12°N, 266°– 274°W, centered at 11.6°N, 269.5°W. This is at low elevation (À3600 to À3900 m MOLA), is flat (MOLA RMS slope = 0.57°), radar data suggest a smoother surface at decimeter to meter scales(More)

The Stereo Camera System (SCS) was designed to provide wide-angle multi-spectral stereo imaging of the Beagle 2 landing site. Based on the Space-X micro-cameras, the primary objective was to construct a digital elevation model of the area in reach of the lander's robot arm. The SCS technical specifications and scientific objectives are described; these(More)
One hypothesis for the origin of the nanometer-size diamonds found at the Cretaceous-Tertiary (K-T) boundary is that they are relict interstellar diamond grains carried by a postulated asteroid. The (13)C/(12)C and (15)N/(14)N ratios of the diamonds from two sites in North America, however, show that the diamonds are two component mixtures differing in(More)
Frozen CH 4 and CH 4 /Ar were irradiated by protons and 3 He 2+ ions at 15 and 77 K in order to simulate the interaction between the solar wind and the surface of comets. After irradiation , polymerised organic matter is left over as solid residues, when warming up the remaining CH 4. The carbon isotopic composition of these residues was determined.(More)
The Murchison and Allende chondrites contain up to 5 parts per million carbon that is enriched in carbon-13 by up to + 1100 per mil (the ratio of carbon-12 to carbon-13 is approximately 42, compared to 88 to 93 for terrestrial carbon). This "heavy" carbon is associated with neon-22 and with anomalous krypton and xenon showing the signature of the s-process(More)
