#Life on #Mars may be hiding or eing bdormant. See my new blog on Big Think with the various options how it may alude us:

How a scientific mistake derailed Mars exploration for 50 years. What if Viking actually did discover life on Mars ? See blog with our link to eLetter in Science at (all blogs with link also on my website https://t.co/m5btzUkpUy) :

The question of what is #life and its #definition: still way more questions than answers. See my blog on this topic on BigThink

#Ceres - the forgotten #ocean world. Its all frozen now, but we still could find remnants of early #life on this dwarf #planet within the #asteroid belt

@DanEBengtson Thanks ! Will look for it !

[Dirk Schulze-Makuch @extreme_microbe]

When and where did #life begin? New #research shows that time is even shorter than we thought, triggering thought provoking questions !

@DanEBengtson Dear Daniel, where is your book published and what is its title? Of course, what you are saying cannot be excluded as possibility, but what would your suggested location make so special that is not there on early Earth? Best, Dirk

The new Vera Rubin observatory will make a big difference in the chance of detecting #technosignatures, signs of #alien #technology. Its a new blog by Tony Reichhardt and myself on BigThink.

Microbial motility as an amazingly simple #biosignature to detect #life on #Mars and elsewhere (and dangerous #pathogenic #bacteria on Earth). Posted on BigThink with Link at

This week, there's a bonus #SETILive! @allplanets discussed @extreme_microbe's recent @NatureAstronomy article about how we should follow the salts🧂 instead of the water💧 when looking for life on #Mars🔴.

[Dirk Schulze-Makuch @extreme_microbe]

@DanEBengtson yeah, that would work as well

[Dirk Schulze-Makuch @extreme_microbe]

We may be looking for #life on #Mars in the wrong places. The Viking life detection experiments might have inadvertently killed indigenous Martian life by applying too much water. We should follow the salt !

@BrianCoryDobbs e.g. Mancinelli, R.L. (1989). Adv. Space Res. 9, 191–195., 25-250 ppm of H2O2 on the Mars surface. H2O2 in the organisms or the soil could explain the CO2 release in the Viking GCMS as could perchlorates. Steven talks about LR, and the interpretation of that is more complicated

[Dirk Schulze-Makuch @extreme_microbe]

@BrianCoryDobbs There is H2O2 on Mars, the question is only if putative microbes use it. The CO2 released when baking Martian soil in the Viking GCMS could point to it (or perchlorates?) - when heated, both compounds become unstable and the organics in the sample would be oxidized to CO2

[Dirk Schulze-Makuch @extreme_microbe]

@DanEBengtson Only if there is the salt that reduces the freezing points and you have little island of molten ice/liquid water

[Dirk Schulze-Makuch @extreme_microbe]

@BrianCoryDobbs Please read the paper. Through hyperhydration. At some point, the putative microbes couldn´t cope with it anymore. Also, please check out https://t.co/quIj57Hwzv
