Query about Mars
"Andrew McKay" wrote in message ...
I was musing about the following situation, maybe someone can offer some thoughts? WRT to Mars my current understanding is that the climate is harshly carbon dioxide (is it?). If it is then we know that trees and plants can change carbon dioxide into more friendly climatic gasses for human habitation. So if there were water deposits found on Mars, how viable would it be to engineer some serious vegetation on the planet so that the atmosphere starts to develop more human friendliness? . . . Let's say... some forms of life, we'll call them "luman beings," are searching this section of the galaxy for a new place to live. The lumans come across our Sun and find that the third planet from the star has the best overall rating to support their species. But they just have to make a few... uhm... adjustments to make the planet perfectly suitable for lumans. It's unfortunate that these "adjustments" will eradicate all forms of life presently residing there. But who cares? The lumans are only interested in making a place for themselves. Other life forms are insignificant and can be anhilated. For lumans, it's okay to develop other planets toward more "luman friendliness." Are we human? or luman? Andrew Problems scheduling resources?

Query about Mars
David I'm watching what I say. Let me ask you this does Mars atmosphere
have an ozone layer? A very well received theory put together in 1996 by a German biochemist has the precursors of life may have first formed around volcanic cracks in the ocean floor. His reasoning the earth's atmosphere 3.5 billion years ago had no ozone layer. Without a ozone layer there is no protection against ultraviolet radiation. Not until 3 billion years ago did the earth create an ozone layer and then life took off. I think there has to be oxygen in the atmosphere to create ozone. Has the Martian atmosphere some oxygen? I posted not to long ago that a planet two times bigger than the earth,and lots of surface water heated by the planet's internal heat could be more beneficial to life than a planet near a sun,and no way to block out harmful radiation. Harmful radiation from our sun kills a half million people a year Still I like our sun,but I'm smart enough to stay in the shade. Bert . |

Let me ask you this does Mars atmosphere have an ozone layer? Not like the Earth's. There is a small amount of Ozone in the atmosphere of Mars (about 0.03 ppm at the surface), but its shielding effects are fairly small. Without a ozone layer there is no protection against ultraviolet radiation. Life originating in seas and oceans might also have some protection by being under water. Has the Martian atmosphere some oxygen? Yes, it does, although again, the amount is fairly small (Martian Atmospheric composition at the surface: 95.32% Carbon Dioxide, 2.7% Nitrogen, 1.6% Argon, 0.13% Oxygen (diatomic), 0.03% Water Vapor, ect.). -- David W.

Query about Mars
Bert posted:
Lets say that these Christmas Mars landers all land(that is doubtful) Well, there are no *landings* (note the plural) scheduled for Christmas. There is only one landing scheduled for that day (the British Beagle-2). The only other landings will be the Mars Exploration Rovers, and they are scheduled to reach Mars in January of 2004 ("Spirit" will reach Mars on January 4th). Unlike you, I am hopeful at least one of these landers will make it down successfully. Lets say half of their probing equipment works. Lets say more than 80% works. They find nothing more than what the 1962 Mars lander showed us (dust and rock.) What?!! There was *NO* Mars lander in 1962! We hadn't even soft landed on the moon in 1962, and the first probe to Mars didn't get there until 1965! A successful Martian soft landing was not achieved until July 20th, 1976 with the Viking-1 lander, so again, you are off by about 14 years! The last lander which reached the surface succesfully was Pathfinder in July of 1997. Where in the world are you getting your information?? Would we go back again? We will as long as questions remain to be answered about Mars (and even with the new rovers, questions will remain, as many of the more interesting areas on the planet have yet to be fully explored on the surface). I just hope we don't have any antenna problems,for that has been NASA biggest problem. Hardly. The biggest problems with NASA are lack of money and a somewhat lack of vision. -- David W.

I think he's referring to the Galileo HGA, which crippled that mission, and possibly the recent problem with SOHO. But why not simply kill-file the guy?

...why not simply kill-file the guy? You won't teach him anything. The which Painius responded: This surprises me, Jonathan! Bert is sometimes inaccurate and frequently imprecise, and yet he's rarely off-topic. More importantly, you have no idea how much i've learned from David and Bert as a result of their backnforths. Sometimes what is perceived by some as trolling is merely a useful Devil's Advocate thingie. I'm not saying that Bert does this on purpose, but it seems that sometimes this is how it turns out. Bert has been a benefit and an asset in more ways than one. Besides Painius' aforementioned example, I have on several occasions grabbed some 'insights' as a direct result of interacting with Bert. On another occasion about 3=BD years ago, Bert (then known as Herb) was posting on the subject of gravity-inertia equivalence. Interacting with Herb, I did a web search on that subject. Totally fortuitously, I ran onto Henry Lindner's flowing-space model of gravity and his 'clearing house' of other people's flowing-space models of gravity(!!). I about fell over. Up to that moment, I had no idea that other people besides Wolter have been intuiting the very same model. So I owe Herb (er, Bert) an unending debt of gratitude for steering me onto this fortuitous find. Thanks, Bert. oc |

We here all love science, and that is our common denominator. =A0 You said it all right there, Bert. Moreover, it don't hurt to apply a little intuitive extrapolation (IE) 'outside the box' of the visible cosmos once in a while. oc |

Query about Mars
Hi BV It all came down to politics. New brains came into NASA ,and they
took one look at the Saturn and said it had no wings.(they were aircraft engineers.from calif.) Just think if they did not scrape the Saturn,and just improved on it(let it evolve) We would have gotten a bigger bang for our bucks than staying in low earth orbit for 36 years(yes?) We missed the chance of a life time to have as you say a base on the moon. What we have now is nothing. And that is very sad. Bert |

Query about Mars
Hi Jeff What Scott posted is true the Saturn V could build a base on
the moon,but it was not reuseable. The Shuttle on the other hand can go round and round 300 miles up(low orbit) for 113 orbits,and only blow up twice. Killing 12 astronauts,and waste 36 years. Seems 40 years ago there was a choice to build a base on the moon or stay in low orbit for the next 36 years. I went for the moon,for with the Saturn V its only 3 days away. I have been flamed for going in that direction for all those years(still am) When you think of outer space you have to think big. You have to have great vision. We throw billions of dollars away by not recycling plactic jugs cans,and the Saturn V was not recyclable but what a bang it gave for the buck. We should have sent one up to the moon each 4th of July ,and with 36 trips we would have a base on the moon flying the American flag. Now we have nothing. Bert |
