Binary choice experiments under natural solar radiation were used to test short- term behavioral responses of freshwater calanoid copepods to ultraviolet radiation (UV). Responses of the nine species from 15 populations spanning North and South America included both UV attraction and UV avoidance, and varied among habitats, species and populations....

Lakes were abundant and active on early Mars for 100s millions of years. As global climate change prevented liquid water from remaining stable at the surface, they left behind key evidence of their past existence and duration in the landscape morphology, mineralogy, composition, and topography. As significant markers of environmental change, they h...

Journal of Raman Spectroscopy
Laser Raman spectroscopy (LRS) has been proposed for in situ characterization of molecular species in planetary surface exploration, and three laser Raman spectrometers are included in the science payloads of two under-development missions to Mars (ESA- ExoMars2018 and NASA-Mars2020). We report the first rover test of a laser Raman spectrometer dev...

This field report describes the design and operations of the Planetary LakeLander (PLL) probe and its ground data systems. LakeLander s primary mission is to characterize the physical, chemical, and biological processes occurring in a high-altitude lake, and how they are being impacted by rapid deglaciation. LakeLander s secondary purpose is to tes...

Transparency is a fundamental characteristic of aquatic ecosystems and is highly responsive to changes in climate and land use. The transparency of glacially-fed lakes may be a particularly sensitive sentinel characteristic of these changes. However, little is known about the relative contributions of glacial flour versus other factors affecting li...

This work presents a method with which to automate simple aspects of geologic image analysis during space exploration. Automated image analysis on board the spacecraft can make operations more efficient by generating compressed maps of long traverses for summary downlink. It can also enable immediate automatic responses to science targets of opport...

[1] Science missions have limited lifetimes, necessitating an efficient investigation of the field site. The efficiency of onboard cameras, critical for planning, is limited by the need to downlink images to Earth for every decision. Recent advances have enabled rovers to take follow-up actions without waiting hours or days for new instructions. We...

[1] We performed laboratory laser-induced breakdown spectroscopy (LIBS) and laser Raman spectroscopy measurements on samples from a layered outcrop from the Atacama Desert, Chile. This outcrop is a terrestrial morphological and possibly mineralogical analogue for similar formations that will likely be investigated by the Curiosity rover at Gale Cra...

On Earth, lakes provide favorable environments for the development of life and its preservation as fossils. They are extremely sensitive to climate fluctuations and to conditions within their watersheds. As such, lakes are unique markers of the impact of environmental changes. Past and current missions have now demonstrated that water once flowed a...

Lakes on Mars, Edited by NA Cabrol and EA Grin. Elsevier BV ISBN 978-0444528544, 2010, p. 347-370
As discussed in previous chapters, identifying traces of water activity and ancient aqueous sedimentary basin deposits was an essential step in documenting whether early Mars was habitable. Evidence for a wetter history was provided repeatedly during the past 40 years of exploration by orbiters and more recently from the ground by the MER mission. ...

Lakes on Mars
Lakes are time capsules. On Earth, they are considered sentinels of climate change (Williamson et al., 2009) and may have played the same role on early Mars (eg, Baker, 2001; Cabrol and Grin, 2002, 2005). Their basins capture the record of geological and environmental fluctuations over a wide range of temporal and spatial scales (Figure 1.1). Terre...

Total DDs observed were 533 in season one, 101 in season two, and 127 in season three. Their general characteristics are the same within factors of 2 among the seasons, with median diameters of 19 m in season one, 24 m in ...

[1] The Chilean Altiplano is the westernmost part of a large volcanic-sedimentary plateau in the central Andes. High solar irradiance and rapid increase of temperature have contributed to make it a hot spot of global climatic change. In this study, we describe microbial diversity in the summit lake of the Simba volcano (5,870 m) and the evaporitic ...

When remotely navigating a mobile robot, operators must estimate the slope of local terrain in order to avoid areas that are too steep to climb or that slope so steeply downward that the operator would lose control of the rover. Although many rovers are equipped with sensor systems to aid the operator in this task, it is sometimes necessary to esti...
