As announced by Prof. Roberto Orosei during the live on July 30 on this page (see https://youtu.be/wQPjWA0tL0Y?t=8998), there is a network of salt lakes under the ice of the South Pole of Mars!Around the lake discovered in 2018 by an Italian group, there are three others, described in the journal Nature Astronomy by the same authors of the first study, coordinated by Elena Pettinelli and… Read More »Mars, under the ice of the South Pole a network of salt lakes

At 11:56:24 UTC the Mastcam Right re-imaged the excavation named “Mary Anning 3” (see https://www.facebook.com/PianetaMarte.MdM/posts/3232966906786480 and https://www.facebook.com/PianetaMarte.MdM/posts/3241879602561877). By comparing with the previous images, we have confirmation that the excavated material has undergone the same changes observed in the previous excavation (see https://www.facebook.com/PianetaMarte.MdM/posts/3176207112462460). It would seem that this second excavation in the Mary Anning area served to confirm the detection of particular organic compounds, not yet… Read More »Curiosity Sol 2887, September 19, 2020

At 01:40:57 UTC the Mastcam Right re-shot the excavation named “Mary Anning 3” (see https://www.facebook.com/PianetaMarte.MdM/posts/3232966906786480). A comparison with the previous image, taken only two days earlier, shows the same changes observed in the previous excavation (see https://www.facebook.com/PianetaMarte.MdM/posts/3139037619512743). The extreme similarity between the two excavations, however, performed in the same area (Mary Anning), makes me suspect that during the first analysis of the previous excavation has… Read More »Curiosity Sol 2872, September 4, 2020

At 03:05:00 UTC the Mastcam Right filmed the new excavation in the rock performed by the Curiosity driller.This drilling, called “Mary Anning 3”, is 1.6 cm wide and shows us the true color of the rock apart from the reddish layer that covers it.Also in this case, as for the previous excavation (see https://www.facebook.com/PianetaMarte.MdM/posts/3134289306654241), the excavated material appears of a very faded pink, although the… Read More »Curiosity Sol 2870, September 2, 2020

At 23:10:25 UTC Mastcam Right imaged this gorgeous layered rock, with clear or perhaps reflective layers.Limestone veins are visibly present in this rock, but some very clear areas look particularly reflective rather than limestone rich. The only confirmation will come either with more photos or direct analysis.Let’s wait and see which of the two hypotheses will eventually be confirmed.The original image is a black and… Read More »Curiosity Sol 2867, August 29, 2020

Using data from NASA’s InSight lander, seismologists at Rice University on Mars have made the first direct measurements of the three subsurface boundaries, from the crust to the core of the red planet. “Ultimately, it could help us understand planetary formation,” said Alan Levander, co-author of a study available online this week in Geophysical Research Letters. While the thickness of Mars’ crust and the depth… Read More »Analysis of NASA lander’s seismograph data reveals boundaries from crust to core

At 13:38:08 UTC the Mastcam Right re-shot the excavation called “Mary Anning” (see https://www.facebook.com/PianetaMarte.MdM/posts/3150638091686029 , https://www.facebook.com/PianetaMarte.MdM/posts/3139037619512743 and https://www.facebook.com/PianetaMarte.MdM/posts/3134289306654241). From the comparison with the previous image, taken nine days earlier, no particular chromatic differences can be seen. On the other hand, it can be seen that most of the excavated material has been dispersed by the wind, mainly towards the lower right corner of the image,… Read More »Curiosity Sol 2852, August 14, 2020
