After a child has been missing for a number of years, a photograph of the child is of limited use to law enforcement officials and the general public. In order for a picture to be of any use, it should be artificially aged to provide at least an estimate of what the child currently looks like. This age progression can be done by a forensic artist using specialized computer software; however, this...
We are developing a portable laser desorption resonance ionization mass spectrometer (LDRIMS) for determining the radiometric age of rocks using the 87Rb-87Sr isotope system, as well as constraining lithologic evolution and measuring chemical compositions. The bench-top prototype has been used to assess the capability of LDRIMS to measure 87Sr/86Sr. In this paper, we demonstrate that LDRIMS can measure...
XTRA is a miniature XRD/XRF instrument intended for use on small rovers and landers destined for solid solar system objects without substantive atmospheres (i.e., the Earth's Moon, asteroids, comets, Mercury, or the moons of Mars. The technology of XTRA derives from the CheMin XRD/XRF instrument on Mars Science Laboratory (MSL), augmented by improvements developed through Small Business Innovative...
