MAVEN Spies Mars' Atmosphere Leaching Out Into Space
astroengine writes: Early results from NASA's recently arrived MAVEN Mars spacecraft show an extensive, tenuous cloud of hydrogen surrounding the red planet, the result of water breaking down in the atmosphere, scientists said Tuesday. MAVEN, an acronym for Mars Atmosphere and Volatile Evolution, arrived on Sept. 21 to help answer questions about what caused a planet that was once warm and wet to turn into the cold, dry desert that appears today. "It's measurements like these that will allow us to estimate the escape rate of hydrogen from the Martian atmosphere to space today. It's an important measurement to make because the hydrogen ... comes from water lower down in the atmosphere," MAVEN scientist Mike Chaffin, with the University of Colorado, Boulder, told reporters on a conference call.
Oh, pleese!
Does this mean that some of Earth's atmosphere might be leaking out into space? If that is the case, I hope all the oxygen disappears so all the white people will die.
So my first guess here, as hydrogen is abundant in the martian atmosphere and it's nickname is 'the red planet', is that the abundance of iron in the planet's crust caused the consumption of water so that the greenhouse process was stopped?
but the sun. One day it will be large enough to consume earth, mars, and other planets. For that day to come a bit later I propose to cast mars into the sun as a sacrifice for our radiant goddess.
The best certifications in computing come from your own actual experience. When I joined the World's Largest Software Corporation to work on the Largest Software Project in the History of Mankind, I asked them if I should get some certifications. They laughed and laughed, said it was just a marketing program, and not to waste a minute of my time on them. Being an actual software development engineer there was all the certification I was ever going to need, because for every 1000 resumes they received, they hired one person.
They were right. These are marketing programs. They are a waste of time, and you don't want to spend your career working for anyone who puts any faith in them.
So, in the long term the tendency is Mars losing their atmosphere and become a rock without air. Bad news for terraforming plans and long-term colonies :-(

Good images, but quite useless to view without a little information. How does the Spectrograph present it's images - or a better question - how long did it take for MAVEN to collect the data for these few preliminary images? The voids in two images make them appear to be incomplete.
I'm wondering what effect our past missions have made to build up the hydrogen cloud around Mars, and how well Mar's two moons sweep up the high atmosphere.
Charged particles are separated by our magnetic field and enter the athmosphere at the two poles. The charge either dissipate staticly - through surface phenomena - or as electron exchanging current. So, do you propose the static charge at the poles accumulate as to create static clouds and pools that migrate, or that enough charge gets accumulated to break down the dielectric constant of air, water and rock?
There should be readily available information to answer your question.
I'd love to see how it compares to the expected values. Can you stick it into a model based on the known equations, turn the crank, and tell what the temperature used to be on Mars thousands of years ago? Hrmm, would be a fun thesis topic.

That an asteroid smashed into the planet disrupting its core. With the core disrupted, it no longer is the furnace that our planet is and being a molten metal furnace that spins, this creates our magnetic field that keeps the solar particles flowing by the planet and most of our atmosphere in.
Without its central magnetic field (Mars has many small ones) there is no effect large enough to prevent solar winds from stripping the atmosphere from the planet over time.
The reason for mars losing its atmosphere is already understood, it is disingenuous to continue to call it a "mystery"
The core of mars was not formed with enough thorium to warm the core with radioactive decay in the long term. Once the potassium-40 and Uranium petered out, the liquid circulating metal of the core cooled and solidified. The magnetic fields produced by the circulating metal deflected the solar wind and protected the atmosphere.
Thankfully earth has plenty of thorium in its core for many years to come. Keep those Van Allen belts buckled tightly around our blue orb. Thanks for reading!
I think you know how to use the internet to learn new things. But where's the proof. I'm not trying to be argumentative but I would really like to know. Because I'm under the impression that most people know how to do a simple search on the internet, this has yet to be proven, much like black holes (?)
