Searching for Organics under a Simulated Mars Robotic Drilling Mission (Rio Tinto, Spain): What Lies Underground?

Rosalba Bonaccorsi Stoker, Carol

We present here results on the preservation of organics in highly oxidized rock materials and clay layers drilled from 0-6m-depth (Borehole-7) under the Mars Analog Rio Tinto Experiment (MARTE). This simulated a Mars robotic drilling mission at the RioTinto (Spain)[2, 5]. The RT represents an important analog of the Sinus Meridiani Mars Site, and a...

We present the results of a survey of 45 young (

Figure of the double Asteroid 90 Antiope from adaptive optics and lightcurve observations

Published in Icarus

A long-term adaptive optics (AO) campaign of observing the double Asteroid (90) Antiope has been carried out in 2003–2005 using 8–10-m class telescopes, allowing prediction of the circumstances of mutual events occurring during the July 2005 opposition [Marchis, F., Descamps, P., Hestroffer, D., Berthier, J., de Pater, I., 2004. Bull. Am. Astron. S...

Molecular Hydrogen Formation on Amorphous Silicates Under Interstellar Conditions PDF available through Get Fulltext Research

Perets, Hagai B. Lederhendler, Adina Biham, Ofer Vidali, Gianfranco Li, Ling Swords, Sol Congiu, Emanuele Joe Roser Manico, Giulio Brucato, John Robert ...

Experimental results on the formation of molecular hydrogen on amorphous silicate surfaces are presented for the first time and analyzed using a rate equation model. The energy barriers for the relevant diffusion and desorption processes are obtained. They turn out to be significantly higher than those obtained earlier for polycrystalline silicates...

Global warming and climate forcing by recent albedo changes on Mars

Lori Fenton Geissler, Paul E Haberle, Robert M

Published in Nature

For hundreds of years, scientists have tracked the changing appearance of Mars, first by hand drawings and later by photographs 1, 2. Because of this historical record, many classical albedo patterns have long been known to shift in appearance over time. Decadal variations of the martian surface albedo are generally attributed to removal and deposi...

Radio Astrometric Detection and Characterization of Extra-Solar Planets: A White Paper Submitted to the NSF ExoPlanet Ta...

Bower, Geoffrey C. Bolatto, Alberto Ford, Eric Paul Kalas Ulvestad, Jim

The extraordinary astrometric accuracy of radio interferometry creates an important and unique opportunity for the discovery and characterization of exo-planets. Currently, the Very Long Baseline Array can routinely achieve better than 100 microarcsecond accuracy, and can approach 10 microarcsecond with careful calibration. We describe here RIPL, t...

Looking for Giant Earths in the HD 209458 System: A Search for Transits in MOSTBased on data from the MOST satellite, a ...

Moffat, Anthony F J Rucinski, Slavek M Weiss, Werner W Croll, Bryce Matthews, Jaymie M Jason Rowe Kuschnig, Rainer Walker, Andrew Gladman, Brett Sasselov, Dimitar ...

Published in The Astrophysical Journal

We have made a comprehensive transit search for exoplanets down to about 2 Earth radii in the HD 209458 system, based on nearly uninterrupted broadband optical photometry obtained with the MOST (Microvariability and Oscillations of Stars) satellite, spanning 14 days in 2004 and 44 days in 2005. We have searched these data for limb- darkened transit...

Very high contrast IFU spectroscopy of AB Doradus C: 9 mag contrast at 0.2" without a coronagraph using spectral deconvo...

Abuter, Roberto Tecza, Matthias Eric Nielsen Clarke, Fraser J Close, Laird M Thatte, Niranjan

Published in arXiv preprint astro-ph/0703565

We present an extension of the spectral deconvolution method (Sparks & Ford 2002) to achieve very high contrast at small inner working radii. We apply the method to the specific case of ground based adaptive optics fed integral field spectroscopy (without a coronagraph). Utilising the wavelength dependence of the Airy and speckle patterns, we make ...
