Mysterious Martian "Cauliflower" May Be the Latest Hint of Alien Life | Science | Smithsonian

In 2008, scientists announced that NASA’s Spirit rover had discovered deposits of a mineral called opaline silica inside Mars's Gusev crater. That on its own is not as noteworthy as the silica’s shape: Its outer layers are covered in tiny nodules that look like heads of cauliflower sprouting from the red dirt.

No one knows for sure how those shapes—affectionately called “micro-digitate silica protrusions”—formed. But based on recent discoveries in a Chilean desert, Steven Ruff and Jack Farmer, both of Arizona State University in Tempe, think the silica might have been sculpted by microbes. At a meeting of the American Geophysical Union in December, they made the case that these weird minerals might be our best targets for identifying evidence of past life on Mars.

There's a spacewalk scheduled for tomorrow on the ISS -
this time it's the Russian cosmonaut's turn! Spaceflight101 has all the details.

NEBULA: jsou to skutecne ruzne casy, ted jsem si to pro jistotu overil. ale nejstarsi je kupodivu snimek, kde jsou duny skoro cele tmave. tady jsou odkazy do katalogu (vyrezy, co jsem postoval niz, jsou z grayscale non-map verzi):

CLUMP: loni se hirise na sezonni zmeny tehle skvrnicich oblasti docela soustredil a radu z nich vyfotil treba trikrat s ruznymi casovymi odstupy. prisel jsem na to nahodou pri prochazeni katalogu snimku, nevsimnul jsem si, ze by to nekde avizovali. at uz je to cokoliv, snad k tomu driv nebo pozdeji vydaji nejakou studii nebo aspon clanek se srovnanim.

srovnejte napriklad ruzne faze tehle dun (snimek v predchozim prispevku patri myslim mezi tyhle dva):

Life in the dark dune spots of Mars: a testable hypothesis - ResearchGate
http://www.researchgate.net/...n/252158441_Life_in_the_dark_dune_spots_of_Mars_a_testable_hypothesis

ABSTRACT: This chapter presents one of the very rare exobiological hypotheses. The main thesis is that there could be life in the dark dune spots (DDSs) of the southern polar region of Mars, at latitudes between –60° and –80°. The spots have a characteristic annual morphological cycle and it is suspected that liquid water forms in them every year. We propose that a consortium of simple organisms (similar to bacteria) comes to life each year, driven by sunlight absorbed by the photosynthetic members of the consortium. A crucial feature of the proposed habitat is that life processes take place only under the cover of water ice/frost/snow. By the time this frost disappears from the dunes, the putative microbes, named Mars surface organisms (MSOs) must revert to a dormant state. The hypothesis has been worked out in considerable detail, it has not been convincingly refuted so far, and it is certainly testable by available scientific methods. We survey some of the history of, the logic behind, the testable predictions of, and the main challenges to the DDS-MSO hypothesis.

Úžasný post-sovětský retro-futurismus... zvým způsobem fascinující a postmoderní... vezmete kus atompunku z 50tých let a postavíte mu skanzen na Sibiři :-) (ale co už, Von Branu byl zase nácek...)
