Neutron environments on the Martian surface.

Physica medica : PM : an international journal devoted to the applications of physics to medicine and biology : official journal of the Italian Association of Biomedical Physics (AIFB), 2002
Radiation is a primary concern in the planning of a manned mission to Mars. Recent studies using NASA Langley Research Center's HZETRN space radiation transport code show that the low energy neutron fluence on the Martian surface is larger than previously expected.

Acoustic environment of the Martian surface

Journal of Geophysical Research: Planets, 2001
Prompted by the Mars Microphone aboard the 1998 Mars Polar Lander, a theoretical study of the acoustical environment of the Martian surface has been made to ascertain how the propagation of sound is attenuated under such conditions and to predict what sounds may be detectable by a microphone. Viscous and thermal relaxation (termed classical absorption),

On the composition of martian surface materials

Icarus, 1967
Abstract Observations were made of Mars with the birefringent interferometer. These observations when combined with spectra of the Sun show that Mars has an extremely strong band at 3.1 μ. This band is presumably produced by hydrated minerals on the surface of Mars.

Dielectric Map of the Martian Surface

2005
We have undertaken laboratory electromagnetic characterization of the total set of minerals identified by TES [1] on the Martian surface in order to investigate experimentally the dielectric properties of the sediments covering it in the frequency range from 1 to 1000 MHz.
