Recurring Slope Lineae: Confirmation of shallow subsurface flowing water on Mars

David StillmanAbstract:  Recurring Slope Lineae (RSL) are narrow (0.5 to 5 m) dark albedo features that incrementally lengthen down steep slopes and reoccur each year. RSL are well correlated with temperature, as they lengthen as temperature increases and fade as temperature decreases.

Extending the search for ETI communication to near-infrared wavelengths

We are poised to take advantage of a remarkable confluence of technological advances and scientific opportunity. For the first time, very fast, wide bandwidth, high-gain, low noise near-infrared avalanche photo diode (APDs) detectors are available and reasonably priced. We are designing and constructing a new SETI instrument to search for direct evidence of interstellar communications via pulsed laser signals at near-infrared (900 - 1700 nm) wavelengths.

Sight-seeing in the 21st century -- ices, sand, water, and dust in motion on Mars

Humankind's earnest reconnaissance of Mars, made possible by advances in our technology, has progressed significantly over the past 150 years. Early ideas of vibrant macroscopic life on Mars in the late 19th and early 20th centuries gave way to a perception of a barren desert world 

Remote sensing survey of Valles Marineris: insights into magmatic and sedimentary processes on Mars

valles marinerisValles Marineris is a unique vertical section through the uppermost kilometers of the martian crust; its location, east of Tharsis bulge, and its water-related history are responsible for a great diversity of rock types in this area. High resolution morphological (HiRISE) and mineralogical (CRISM) data from the MRO mission (NASA, 2006) available over the area were investigated.
