New Mars Forums

I have all the structural Geology done for my BS, actually the advanced Structure I took is a borderline GRaduate level class, but my Geophysics is very weak..  so, I am no help there.  I do plan on going back to school, and finishing my degree in Geology.. so maybe at somepoint I can become more helpful...

This is a good shot of a 'possible' channel and ox-bow lake.(what happens when a meander is cut off from the channel copmletely but due to the water table still has water in it, until such time that it fills in by natural sediment build up. 

The other two pictures are nowhere near as persuasive as the ox-bow lake with the channel.  But they could be 3 billion years old.

My bad, LAT and Long was given, and I would say it would be sufficiently north to also show for glaciation.

Medial Moraine

The only thing that I could speculate on is some sort of medial moraine deposits associated with glaciation.

DR. Zubrin brought up a good point when he talked about Mars Direct. 

Many components of the Mars Direct could be used to goto the moon, and it would be a good idea to work out the bugs on an extended moon mission, where SNAFUs can be fixed much easier. 

Also, many bugs on unmanned craft would never be an issue on a manned spacecraft.  With the ability to interface with computers and such, the human in space can often times thwart the bugs caused by the humans on Earth.

Radio Free Mars, audio of Dr. Zubrins testimony

If you haven't heard it, you should listen to Dr. Zubrins testimony.  It also has a brief question/answer session.

WOW!

About damn time!

That was an awesome speech, I am hoping that it did not fall on deaf ears.  I imagine we will find out in 48 days..  I hope some good comes from this!

Why pay for life support systems and other unessential gear un a craft meant for cargo?  Just taking the unneeded equipment out would costs millions..(worked around government contracts)

OSP is for 4 people.  I have doubts about ISS right now..  I think everyone does.  Getting OSP built is not 'definite' Getting 6 people there in the next 10 years may be a bit oerly optimistic.

Most important thing about the rs-84 engine?

It's re-useable! RE-usable Heavy lift. opposed to EELV style

I don't remember where I saw it but NASA is reasearching a new heavy lift rocket motor.. R-84 or something.  looking for 1 Millions LBs thrust.  possbile full scale test by 2007.  Ummh.  A basic 4 person capsule would work in the interim.  If it could have a minimal developement cost, I say go for that, then in the mean time develop the space plane.  spend a bit mroe money over a bit more time to develop something that is a bit better.  like the U-2/SR-71.  The U-2 was a cheap easy Interim and the SR-71 was the final product.  (who would suspect in 1967 the U2 would be extensivly updated and redesigned, with a 40% increase in size and fly for another 37 years!)

An Educated guess would be Anticlinal deformities, ie rock bent down into a v shape.

Salt doming bunched together(very odd though)

The skin of Gigantic Alligator(just a guess)

That is very odd.  I would like to see that with a very fine detail topographic map.  At first they looked like dunes, but then it hit me..  Nope, they are like ARROYOS.  But the scale..  Who knows until we get some real hi-res.  who wants 6" resolution.   I do I do!

Not to be abrupt, but is this feasible, I know it has been brought up on atleast 3-4 separate occasions with the notion that it was unable to handle the g-forces involved.

I know this is more of a thinking exercise, but I would like to bring up a few points.

One,  The Caldera located in Yellowstone is predicted to erupt in the next 100,000 years due to is cyclical pattern.

Two,  It would put a significantly higher amount of ash/rock/dust into the Atmosphere then 1000 km-cubed/

Three, It is not a mass extinction event like the KT boundary or other various eruptions.  I mix them up but Either Tambora or Krakatoa I thought was nearly 1000 cubic kilometers.

Four, We are very resilient.  Humans are like Cockroaches, with a will to live and some Nuclear power we can survive anywhere, prospering is another thought, but survive, YES!

The other possibility to think about, is would we be able to stockpile enough resources and develop the technology to minimize the effect of such a large scale eruption.

Of course drilling to relieve pressure, at the risk of causeing a smaller slightly devastating eruption might help.  If the Magma has a high quartz content, then it would most likely only prolong the inevitable.  Typically, Violent eruptions happen due to a high quart content in the Magma,  This dramatically increased the Viscosity and stickyness of the Magma.  Magma that comes out of Kileau is the exact opposite.  It is relatively low in Quartz, so it can flow freely.  So, the ability to Relieve pressure may be somewhat diminished.  Volcanos with high Quartz content in their Magma are known for their Violent eruptions, coupled with pyroclastic flows.  Vesuvius, Mt. St Helens, Krakatoa, Tambora.. etc are all have had magma flows with anhigher quartz content.

Well..  I will not discount that life could exist on Mars, I do not find anything living about pictures of craters.  Give me some good Hi-res shots.. let's say 1/8 inch resolution...  of something you think is a species that was one plentiful on Earth and measured on average an inch to two inches long.  BTW.. They existed in environments that were completely different then Mars.   If we are going to find life on Mars, I would Wager it would be a few inches below ground or in the Caps.  Most likely it will be microbial.
