[NatGeo] Mars Curiosity Rover Finds Proof of Flowing Water—A First

post #1 of 29

NASA's Mars rover Curiosity has made its first major science discovery, and it's one for the ages.

Scientists at the Jet Propulsion Laboratory (JPL) in Pasadena, California, announced Thursday that water—fast-running and relatively deep—once coursed over Mars's now bone-dry surface, a finding based on the presence of rounded pebbles and gravel near the rover's landing site in Gale Crater.

Awesome find. So what happened to all of it, if it now just hydrogen and oxygen gas in the atmosphere?

I'm curious about this myself as well, the idea of it happening to mars makes me worry about our lil ol' earth.

Isn't mars atmosphere only like 6% of earths?

No, since a lot of the atmosphere I believe is CO2. Scientists don't know where it is, but theories include it accumulating at the polar ice caps to underground oceans of sorts.

Not sure, but it is definitely thinner due to its lower mass.

Not only that but mars does not have a magnetosphere, thus solar winds blow away most of its atmosphere..

There are two main reasons Mars has a small atmosphere and (if it were there in large quantities) surface water; the size of the planet and the solar wind.

Both the loss of the Martian atmosphere and the lack of surface water can be explained by the size of the planet (particularly its gravity). As a black body of smaller size than Earth, it would have radiated off the internal heat of formation more quickly. The consequence of this is that if there had indeed been a flowing liquid core (similar to Earths, and the mass distribution of Mars would indicate such a feature to have existed) it would have cooled, and stopped producing a magnetic field.

The planet, then (almost) fully exposed to the solar wind would have had the water in the atmosphere broken down by high energy particles. Although evaporation, sublimation etc. would push more oxygen/watervapour/hydrogen into the atmosphere, the gravity of the planet would be unable to sustain the atmosphere. As the solar wind breaks apart water vapour into more basic elemental states, it is easier for the particles to escape the gravitational pull of the planet, thus leaving little surface water, and a small atmosphere.
