NASA’s Curiosity Mars rover is now busily at work carrying out Sol 1748 science tasks.

As reported by Ken Herkenhoff, a planetary geologist at the USGS in Flagstaff, Arizona, the current rover menu involves another touch-and-go given that there is bedrock in the robot’s arm workspace. So the tactical science team selected a block named “Tupper Ledge” for contact science.

Following Alpha Particle X-Ray Spectrometer (APXS) measurements of the elemental chemistry of Tupper Ledge and the Mars Hand Lens Imager (MAHLI) takes a full suite of images of the same target, Herkenhoff notes that the robot’s arm will be stowed to allow Chemistry and Camera (ChemCam) and Right Mastcam observations of a soil target called “No Man’s Land” and a bedrock target dubbed “Sugar Loaves.”

Weekend ripple

Curiosity’s Navcam is slated to then search for clouds above the horizon and the Right Mastcam will snap a couple pictures of “Harris,” a trough in the dark sand.

A drive by Curiosity is scheduled to involve placing the crest of a sand ripple in Curiosity’s arm workspace to allow contact science on the ripple this weekend.

Wheel scuff

“A wheel scuff of the ripple was added by the Rover Planners, which should allow the interior of the ripple to be observed,” Herkenhoff adds.

After the drive and standard post-drive imaging by the rover, its Navcam will search for clouds overhead and the Dynamic Albedo of Neutrons (DAN) instrument will make another active measurement of hydrogen in the near-subsurface.

    f we look at the recent images of Rouver Curiosity, we can see the presence of Gray Rocks, which may mean that we are in the presence of Basalt.
    I enlarged these photos 1000 times, to better analyze and perceive its structure.
    I do not think I’m mistaken in the possible composition of the Rocks but in fact I have another opinion.

    I think we are in the presence of MINERALS, such as Limestone Phosphorus, Basalt, or even Iron and Copper, anything is possible. Including MICRO ORGANISMS that at first sight are not noticeable, but they are present of this I am absolutely certain.
    I would like to point out another aspect that I consider to be absolutely credible, because of the rocky sediments,
    Which have been found at certain sites on the Martian surface, clearly show the evidence that water existed on Mars, these marks show that there was a lot of Lagos or Oceans water, anything is possible so I think we should face this very realistically because WATER is present throughout the Universe in various forms.
    I believe that this Planet in a distant past, not far away was a World with an environment very similar to Earth, I believe a lot in this, and I must not be wrong in my thinking, because this fact obeys the evolution of the Solar System over millions of years .
    The existence of dry ice in the poles of Mars is a clear evidence of this fact, as can be seen in several photos collected by Cassini and Curiosyty in which we can see that these facts are very demonstrative, which proves that on Mars existed Or there is Water, but in various forms, one of them is in the form of dry ice.
    Researchers are stubborn to think about hypotheses, wanting not to accept that Mars had water in its recent past.
    I’m always biting on this issue until the time comes when evidence will come in this direction, then everyone will start giving me reason for my thinking.
    The Presence of water in the Martian soil to a considerable depth, is a hypothesis to be considered very seriously, I will not give up hitting this point.
    Presence of water on Mars, it shows that this Planet in a Past / Present was habitable as it is on Earth today, because water is present everywhere in the Universe in very diversified forms.
    In an earlier research that was done, Scientists put the hypothesis that there is water in the Martian basement I consider this absolutely possible.
    Never forget that the Earth is never unique Planet that contains water, there are many more Planets or Moons of our Solar System that has presence of water, this is an issue that should never be denied or excluded, being accepted as a reality, to be seen With seriousness.
    It is important that we have a very thorough knowledge of the Martian Climate, so that we can have the perception of its geological past.
    However it has 2 aspects not to be despised, because they are crucial in understanding the Mars Atmosphere.
    Studying the Climate of Mars will allow us to understand its past Climate, it will help us understand the Earth’s own Climate.
    It is important that we have a very deep knowledge of the Martian Climate, only so we can have the perception of its Geological past.
    I believe that Mars can be a Geologically Active Planet, having its Seasonal epochs, as shown in recent research, where it can be seen that this Geological and Geophysical activity is present not only on the surface, but there may be an intense activity in the Subsoil, Which is not noticeable by photos, but if you use something similar to a Seismograph, you may notice the presence of Seismic and Volcanic activity.
    It is important that this hypothesis is considered, by the Investigators, because it can be present, even if it is minimal.
    The presence of water on Mars must be seen as a possible reality because WATER is present in our entire universe in various forms.
    This is a very personal opinion, so I’d like you to express what you think about my opinion.
