Current pixel-based methods of image analysis are too computationally expensive to feasibly discover meaningful changes in Mars surface features in NASA's large, continuously expanding database of satellite imagery. We worked on the beginning stages of a more efficient method of change detection that ...
Our analysis of the rover’s position from locomotion data and camera imagery over that time shows that the rover traversed 450.9 m southwards over a flat surface with mild wheel slippage. Soil parameters determined by terramechanics, which observes wheel–terrain interactions, indicate that the ...

Mars is characterized its barren, rocky surface, which is covered with a thick layer of iron oxide, or rust, giving it its distinctive red color. The planet's landscape features a variety of terrain, including vast plains, towering volcanoes, and deep canyons. One of the most notable ...

This paper extends the analysis performed in Viúdez-Moreiras et al. (2017) to provide the first comprehensive diurnal, seasonal, and interannual wind speed characterization of Martian surface wind speeds in terms of Weibull best-fit parameters, based on the complete MSL REMS dataset. This wind ...
difficulties surface when encountering rare or transiently expressed cells2,3. Despite their scarcity, rare cell populations step up to play crucial roles in a variety of biological processes4,5. For example, antigen-specific memory T cells are integral for sustained immunosurveillance and long-term ...
Covering 70 percent of the planetary surface, it is the largest, most complex biome we know. The ocean is a huge, mobile reservoir of heat and chemical mass. As such, it is the "engine" t... R Barga 被引量: 1发表: 2009年 Estimation of the flux density of galactic comets in the...
Erosion by flowing water is one of the major forces shaping the surface of Earth. Studies in the last decade have shown, in particular, that the drainage region of rivers, where water is collected, exhibits scale invariant features characterized by exponents that are the same for rivers around...
2020). The MU is ∼2 m above ground level, so SuperCam’s closest observations on the Mars surface are at ∼2 m distance. The SuperCam Calibration Target assembly (SCCT; Fig. 1c) is mounted at the back of the rover (Fig. 3, left). The targets are between 1.541 and 1.567 m ...
