This small crater within the Hellas Crater is the lowest point on Mars but I can't seem to find any detailed information on it. Not even a name. Anyone have any info on its name, size, how deep it is, atmospheric pressure, temperature ranges, etc?
Sorry if this info is already somewhere else on this site but I can't locate it if it is. |

Should be about 15mb of max air pressure and water boiling point of 13C.

Should be about 15mb of max air pressure and water boiling point of 13C. 13 degrees? I still feel that's a bit chilly for a swim. Serious: Hellas have indeed been mentioned as the best candidate for potential liquid water, even if it might only be in the form of a bit of humidity today. Now that assumption was most likely based on potential airpressure alone, now BuckGalaxy migh thave pinpointed the very spot where there might be a fraction more of that. This polygonal terrain JRehling mention is indeed a sign of that the area have dried up at some point. There's a hypothesis that Mars undergo warmer and more benign periods from time to time, if water have been flowing here comparatively more recently - 10-100 kiloyears or so, it must have been so smallscale we cannot see it in the image resolution we now have for the area. |

I would love to take credit for identifying the lowest elevation on Mars! LOL However, credit to where it's due, I got the op image from here: http://geology.com/articles/highest-point-on-mars.shtml No hard info on the diameter of the crater, but eyeballing it, maybe 20km? |

No hard info on the diameter of the crater, but eyeballing it, maybe 20km? I was looking at Google Mars and I was able to compare the relative size of Badwater Crater to Endeavor Crater where Opportunity is exploring. Endeavor is 22km in diameter and Badwater looks like it's close to twice that size. Then I found this: https://planetarynames.wr.usgs.gov/Feature/15314 Badwater is 33.14 km in diameter according to this link. The zoomable map at this link is worth a look. |
