  • The ChemCam is a fancy camera with an in-built laser, the camera has a telescopic lens. ChemCam can be used in a few different ways. It can zap a rock with its laser which generates a small flash of light, the flash of light has different colours depending on the minerals in the rock, that helps the science team understand what the rock is made of, it can also check the sunlight reflected off the rock without using the laser but that is less accurate. In this case they did not use the laser or the reflected sunlight, they just pointed the telescopic camera high up the mountain and snapped a series of photos of some really rugged terrain that the science team hope the rover can visit one day in the future after it drives higher up the mountain.




  • The current location is Serpentine Rapids in the upper right of the map (North is up)

    The route (shown in blue) that the agency’s Perseverance Mars rover is expected to take as it climbs up the western rim of Jezero Crater is superimposed on this image taken by the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter.

    At upper right is “Serpentine Rapids,” the final geologic location of interest for the Perseverance science team before the rover begins its ascent. “Dox Castle” is a region the science team would like to explore during the rover’s ascent. Two of the first regions the science team wants study at the top of the crater are “Pico Turquino” and “Witch Hazel Hill.”

    Imagery from NASA’s Mars orbiters indicates that Pico Turquino contains ancient fractures that may have been caused by hydrothermal activity in the distant past. Orbital views of Witch Hazel show layered materials that likely date from a time when Mars had a very different climate than today. Those views have revealed light-toned bedrock similar to what was found at “Bright Angel,” the area where Perseverance recently discovered and sampled the “Cheyava Falls” rock, which exhibits chemical signatures and structures that could possibly have been formed by life billions of years ago when the area contained running water.

    The distance the rover will drive to get from Serpentine Rapids to the Aurora Park/Pico Turquino area is about 1.1 miles (1.8 kilometers); the change in elevation between the two locations is about 980 feet (300 meters). The distance covered to go from Aurora Park/Pico Turquino to Witch Hazel Hill is about 1.2 miles (2,000 meters) and the change in elevation is about 820 feet (250 meters).







  • AFAIK - No internationally agreed standard, but a bunch of formats have been proposed.

    They do have some elements like Local Mars Solar time (LMST) that can be calculated for any spot on Mars, these have been used by a number of nations that have sent hardware to the surface

    There’s an in-depth Wikipedia page on Timekeeping on Mars, it covers things like proposed date systems as well as calendars. I would assume that the first human settlers to arrive on the planet Mars would select the system that suited them best before departure. I also assume any settlers that arrive later would likely follow what is already in place, rather than use a different system.
