Discussion Overview

The discussion centers around the recent release of a detailed geological map of Mars by NASA and the US Geological Survey. Participants explore the implications of this new map, its features, and its relation to popular culture, particularly in the context of the film "The Martian." The conversation touches on the technological advancements in geological mapping and the potential for integrating this data into existing platforms like Google Earth.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Meta-discussion

Main Points Raised

  • One participant highlights the advancements in geological mapping due to improved remotely sensed data, emphasizing the reliability of thermal infrared images for analyzing surface morphology.
  • Another participant references the fictional character Mark Watney from "The Martian," indicating a personal connection to the map through popular culture.
  • A different participant mentions their creation of an interactive webpage that features various geological layers of Mars, although they note that some technical aspects are outdated.
  • One participant expresses curiosity about how much of the new geological information will be incorporated into Google Earth/Mars, reflecting on their previous experiences with the platform.

Areas of Agreement / Disagreement

Participants appear to share an interest in the new geological map and its implications, but there is no consensus on how the new data will be integrated into existing platforms or its broader applications.

Contextual Notes

Participants mention various technological advancements and personal projects related to Mars mapping, but there are no specific details on the limitations of the new map or the assumptions underlying its creation.

TL;DR
Putting it here, not in space, due to the geological nature of the subject.
NASA and the US Geological Survey have produced a new geological map of Mars.
Better than before.
Very detailed and interesting (to me anyway).
Lots of download options.
This new global geologic map of Mars, which records the distribution of geologic units and landforms on the planet's surface through time, is based on unprecedented variety, quality, and quantity of remotely sensed data acquired since the Viking Orbiters. These data have provided morphologic, topographic, spectral, thermophysical, radar sounding, and other observations for integration, analysis, and interpretation in support of geologic mapping. In particular, the precise topographic mapping now available has enabled consistent morphologic portrayal of the surface for global mapping (whereas previously used visual range image bases were less effective, because they combined morphologic and albedo information and, locally, atmospheric haze). Also, thermal infrared image bases used for the new map tended to be less affected by atmospheric haze and thus are reliable for analysis of surface morphology and texture at even higher resolution than the topographic products.

Here is one of my favorite Martian regions:

So, of course I just had to look up Mark Watney's route which led me to the Wiki page that actually had a map of it... :oldtongue:

I literally just watched The Martian last night on the telly. (Backwards. Tuned in halfway, then it started again.)

I have that colourized altitude map as a 24x36 poster.

And I made an interactive webpage that allows you to switch layers on and off - feature labels for altitude, photo sat data and topology. http://www.davesbrain.ca/science/mars_atlas/
It's a pity I built it so long ago, the JavaScript to rollover labels for every crater larger than 20km is out-of-date. :(

Had to do this to make any sense of Robinson's "Mars" series.

Over the last several years (maybe over a decade or so) I have looked at Mars, the sky, and the moon on Google earth.

I have been looking at the Mars version, and wonder if, or, how much of, the additional geographical information will make it there. As most have, I've looked at the tracks of the old exploration vehicles (and Mark Watneys' trek) on Google Earth/Mars.
