http://www.msss.com/moc_gallery/e19_r02 … 5.html]And one last one

This is the most weird, strange and bizarre landscape I have seen on Mars.

I’ll remind folks that temperatures and pressures, at this location, sometime get where liquid water can exist at the surface. My gut feeling is that this might play a part in this landscape that looks like batter being mixed in a bowl.

Also remember, the is the floor of an impact basin that is 6 miles deep. Could be looking at twisted metamorphic rocks that were either formed from the impact? Could we be looking at metamorphic rocks that were 6 miles under ground until the impactor exposed them?

Or is it some muddy slurry slowly moving around the surface?

So many questions.

Lots of cool pictures, Cindy!

This one show some depth, thanks to the light angle.

Here is an idea I thought about while working on a science fiction story.

I believe there are many wandering worlds roaming interstellar space- worlds that have been cast out of their solar system by their siblings during close encounters.

If this is true, there could be countless worlds waiting for us. If we can figure how to move these worlds, we could do something like move an Earth Mass world into Mars orbit and make Mars its moon.

If we find ones loaded with valuable resourse, we could put them in orbit around Venus.

The Oort Cloud extends from 1 to 3 light years our (Possibly mixing with Alpha Centauri’s Oort Cloud). This is well beyond Voyagers location.

I wonder what effect this interstellar environment has on Oort Cloud worlds, and what happens to one of those small worlds when it cross this boundry.

I believe they are heading (Hopefully not where heading, in the past tense) to a large and very eroded crater called Victoria.

Once they get Opportunity free, then what? Will they keep going all out, figuring if they get stuck again they can get out again, or will they take it very slow? Perhaps there is a way for them to program Opportunity to steer clear of such dunes.

I was thinking they could have Opportunity run parallel with the dunes, and then do a perpendicular cross over when needed.

I don't know where I picked up "thou". Probably some book I read as a kid. I have used it (sparingly) for years.3

As far as Star Trek. Yes, they are always plowing thought the galaxy. And that is the problem. I am always wondering what is going on at home, in the Solar System.

Are they terraforming Venus and Mars? Are they living on the Moon, Mars or any other worlds in the Solar System? Do they mine the asteroids? Are their hotels or bases on any of the Gas Giant Moons? Is Mercury one big industrial complex? What is going on in the Solar System?

This last episode confirmed that in the Star Trek Universe, Mars is being terraformed (I wonder if it was fully terraformed during the Next Generation series?), That there is a self supporting mining colony on the Moon, and that Mars has a colony.

I do know The Next Generation’s Enterprise was built in Mars orbit, so something had to be going on there, but they never elaborated on it.

…and the gas giant hydrogen mines could end up being valuable fuel sources for space crafts.  As for which gas giant to mine, Jupiter is the closest, but its gravity is 2.64. Neptune is the furthest with a gravity of 1.14.

The best candidates are Saturn which is closer but has a gravity of 1.10, or Uranus, which is farther, but has a gravity of only 0.87.

#62 Re: Terraformation » Mars Needs Nitrogen » 2005-05-17 07:14:54

REB

Chat, I was picturing more of a factory (Or thousands of factories) in low Venus orbit. The factory sucks up Venus’s atmosphere and process it. The CO2 is separated into oxygen and carbon. The carbon could be used to built huge tanks to hold gasses, like nitrogen, bound for Mars. Perhaps a similar process, say set up above Saturn or Uranus, could extract valuable hydrogen (There should be plenty of carbon on the moons to make strong carbon nano-tube tanks). This hydrogen could be combined with Venus oxygen to form energy and water.

I think the real key to making this feasible is to make as much of it automated as possible, and have robots do most of the work.

Hi Shaun,

It was the last show of Star Trek's Enterprise series. I came on last Friday in my neck of the wood.

The show ended for good, just when it was getting really interesting sad

The  Synopsis:

In the first steps towards the foundation of the Federation, Captain Archer and the crew must stop Paxton, a well-armed, radical human isolationist leader, who is threatening to destroy Starfleet Command unless all aliens leave Earth immediately. 


http://www.greatlink.org/dcisV2.asp?htt … =1353]More here

And they did do this part, which was really cool.

From the link:
"A couple of things to look out for in this episode: The script calls for a shot where the Shuttlepod flies over the resting place of Sojourner, the Mars rover depicted in the show's opening credits, now dusty and motionless among familiar red rocks. Plans call for a close-up of a Mars Historical Society plaque identifying that 1997 landing spot as the "Carl Sagan Memorial Station." We say "plans" because this shot will be created in post-production, but sometimes budgeting, scheduling and editing demands force compromises. Let's hope this homage to the real space program survives the cut."

I have watched Star Trek for years, and have wondered if in the Star Trek Universe, Mars was ever terraformed. I took a chance with my Peace Offering Star Trek story that Mars had been terraformed.

I was glad to see on the Final Enterprise that Mars was in the process of being terraformed. I liked seeing the Moon and Mars in the Enterprise show. Star Trek rarely shows our Solar System, but I like it when they do and I wish they would have shown more Solar System locations.


They made one mistake, thou. The comet going to Mars was coming from the direction of the Sun. This means the tail would be going towards Mars. There would be a debris trail lagging behind the comet, which they correctly showed.

I liked how they correctly talked, and then showed, about how on the partly terraformed Mars they would not need pressure suits, just thermal suits and an oxygen mask.

I’ll forgive them for moving about Mars like they were in Earth’s gravity (In a base there could be artificial gravity generators, like on their ships, simulating Earth’s gravity, but out on the surface…). Simulating Mars gravity on a show like this would have been difficult.

Overall, I enjoyed the Terra Prime episode showing the Moon and Mars.

http://antwrp.gsfc.nasa.gov/apod/ap990816.html]From 1999:  Mars Weather Watch

I've not seen this collection (4 of them!) of photos before.  What a curl!  Amazing.  Extreme northern Mars.  Says similar storms were observed in the region, during July and August -- "revealing surprisingly complex weather."  That's one of the best weather-related series of photos from Mars, IMO.

--Cindy

::EDIT::  http://antwrp.gsfc.nasa.gov/apod/ap021224.html]Yet another:  Spring Dust Storms @ Mars NP

Excellent photo.  Such detail. 

As the north polar cap begins to thaw, a temperature difference occurs between the cold frost region and recently thawed surface, resulting in swirling winds between the adjacent regions...The choppy clouds of at least three dust storms can be identified.

 

cool

I wonder if Opportunity’s underbelly is stuck on the crest of that dune?

I figure worst case scenario they’ll use the instrument arm boom to push Opportunity off the dune.

Because Mars' atmosphere is effectively inert and can't support combustion, we can use hydrogen for lift without fear of another "Hindenberg" disaster.

Shaun, I saw a show where they came up with good evidence showing it was not the hydrogen that was the problem with the Hindenburg. It was the substance they coated the skin with. It was very flammable.

Witnesses said the Hindenburg’s fire was very orange. Hydrogen tends to burn blue. This promted NASA scientist and hydrogen specialist, Addison Bain, to investigate.

Bain theorized that “static electricity ignited the linen shell of the ship, because it was coated with a nitrate-based paint.”

The show also mentioned that the Germans had Hydrogen safety features in place.

History might have been different if the fear of hydrogen wasn’t instilled on the public. Perhaps we would still have huge Zeppelins in our skies.

Not far to the north from that last picture is http://www.msss.com/moc_gallery/r10_r15 … .html]this area.

Notice the somewhat streamlined crater. It looks almost like is received a blast from one direction.

White frost on Mars red surface reminds me of icing on a cake.

How about using a human made black hole to move planets, moons and other worlds?

Get it just close enough to the world in question, and let it drag that would to where you want it.

http://photojournal.jpl.nasa.gov/catalog/PIA06208]Cool Picture! of Enceladus.

The dome in those craters are probably from water pushing up on the ice where it is the thinnest.

I am betting Enceladus is a smaller version of Europa. But its tidal generated heat is probably more like IO's
