Discussion Overview

The discussion revolves around the presence of water on Mars, focusing on recent discoveries and implications for future exploration. It includes references to images and scientific findings related to water detection on the planet.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants note that water was previously detected on Mars through indirect methods, while this mission represents the first direct detection.
  • One participant suggests that melting ice could potentially contribute to forming an atmosphere, referencing the film "Total Recall" as a hypothetical scenario.
  • Another participant counters that while there may not be enough water to support terraforming, the presence of water at the poles suggests there could be more water below the surface, which could be useful for future missions.
  • A participant shares a vivid description of Mars' landscape, speculating on its historical appearance when water flowed through canyons, and provides details about a specific image taken by the Mars Express orbiter.

Areas of Agreement / Disagreement

Participants express differing views on the implications of water detection on Mars, particularly regarding its potential for terraforming and the sufficiency of water for future missions. The discussion remains unresolved with multiple competing perspectives.

Contextual Notes

There are limitations regarding the assumptions made about the quantity and accessibility of water on Mars, as well as the speculative nature of its potential uses in future exploration.

Yes, water was detected in Mars time before this mission, but that were indirect detections. This is the first direct detection of water in Mars. Is possible to melt some part of that ice to form an atmosphere, in the style of the final scenes of Total Recall?
 
No, not nearly enough for that (which is why Total Recall talked about large quantities of ice below the surface) but enough to prove that there is water on Mars. Up until now, we only had hints and indications that there probably was, and we could say we were almost certain, but now we know for sure.

And if there's water on the surface at the poles, then there is very likely to be water below the surface elsewhere. Maybe not enough for terraforming purposes, but enough for use by future missions. Especially if we go ahead with the manned missions.
 
Imagine how Mars looked when the river that carved this canyon was alive, streaming, jumping, flowing, bubbling, waving :) – so associates on life (some green~fauna around it wouldn’t be bad ;))...

This picture was taken by the High Resolution Stereo Camera (HRSC) onboard ESA's Mars Express orbiter, in colour and 3D, in orbit 18 on 15 January 2004 from a height of 273 km. The location is east of the Hellas basin at 41° South and 101° East. The area is 100 km across, with a resolution of 12 m per pixel, and shows a channel (Reull Vallis) once formed by flowing water. The landscape is seen in a vertical view, North is at the top.
