Build Unlimited Martian Probes.

I see you are the same space exploration maniac as myself, Yirrk

Yes, I was also reading about that Moon Human Knowledge Archive about a year ago.

I for one am very saddened by the way the manned space flight developed.

The start was great - Apollo , then in early seventies it went all horribly wrong .

Returning to the Moon by 2019 in 50 years = 1/2 Century from the first Lunar Landing that is hardly an achievement , let alone progress.

We should have permanent manned Mars bases by then !!!

Yes mate, terraforming of the Mars is only (feasible) way forward

And with a bit of bad luck the asteroid hits the moon before hitting earth.

Not the best idea imo...

The gravitational pull that makes the moon stay in orbit is Earth, if in case something does happen to Earth that would create a disturbance on the orbital path that it follows, if Earth would be destroyed entirely or any other possibilities that can alter the orbital path of planet Earth or for some reason the removal of the entire planet overall by some freakish reason, then what would be the point of having a lunar base, when the orbit of the moon is dependant on that of the Earth and the destruction of the Earth would cause a change in orbit to our Moon, who knows where the moon would actually end up, my best bet is that it would join the closest gravitational mass/pull available at the time, unless there are other forces that would therefore push the moon elsewhere, but it all depends on what the causes for the actual massive exodus are....unless the destruction created is localized (landmass area, planet remains intact as far as mass/size/orbit but no longer suitable to sustain life, etc) I can't see how the Lunar Ark can be used if the Earth is completly wiped off the solar system.

Sounds like a short term plan, but in the longrun, I would say looking after other planets would be much better than our closest satellite moon. Considering also other facts, for example, finding ice, water or bacteria on Mars, I think it would be the most suitable planet to start Terraforming...

Then again, maybe there was life in Mars before to begin with ;-).

Aside from all that, I'm sure that the people selected for such an Ark (if it were to take place) are the elite few involved in the military, government, higher 'ranks' or financial status. No place in the ark for middleclass working people ^^.

Cool articles Yiirk , keep 'em coming!

mmm, cool :P anyone up for a meetup on the moon and play eu (or em (multiverse)? :P


on the other hand....im quite sure that there are/will be other parties involved then just the "save the earthlings" party...

[Solaris]

I demand an immidate production of a new Hollywood doomsday movie commensed NOW!

At least I know where I would definately NOT wanna be in case of a meteor impact!

The loss of the earth wouldnt be a problem so much in loosing its gravitational orbit for two reasons, firstly the likelyhood the earth would be entirly wiped out with no mass left would be very slim, however and impact that could cause all life on the planet to cease is not so unlikely, so the moon could still orbit a dead earth.

Secondly, even if that did happen, the moon would retain its orbit around the sun. Remember there are many asteroids orbiting our sun much smaller than our moon From what i understand anyway...

Exactly my thoughts ! I was gonna post the same thing but then I saw that u posted it first!

Agree with the first point, unlikely but still possible...

Kinda disagree with the second thought (kinda), that if the Earth would vanish from existance (theoretically) the moon would orbit around the sun....but it all depends on the situation...

If the destruction of the Earth left debris of the planet while the moon was intact, the possibility that those debris would reunite (by means of gravitational pull) and the moon would then orbit the debris (since it still has mass) it's feasible and perhaps the debris can then proceed to unite and create a new planet (?), Big maybe...

But you really have to look at how the destruction happened and how bad it was, did the Earth shattered into different 'big' pieces that would then become asteroids and dissipate into different parts of the solar system?

If the moon is thrown off the orbit due to explosion/ destruction of the planet, then it 'runsaway' until it reaches a bigger, massive landmass and would attach itself to it's orbit. The sun being the biggest gravitational pull in our system makes sense, but one word: Momentum, huge maybe's here.

Technically speaking, yes you may be right in the sense that the moon may continue to orbit the sun after the Earth vanishes and may adopt some of the debris that was left off Earth if there is still any around, but this theory only works if...

A- Earth does not interfear with Moon's orbit during or after explosion/destruction/etc.
B- Moon does not interfear with debris from Earth's remains... such debris would cause the moon's orbit to change.
C- The force that created the destruction of Earth would not interfear with the moon...
D- No other parties or 'godly' or natural forces involved (a comet coming into our orbit at the same time that the destruction occured as an example)

Now, my thoughts are, whatever force that creates the Earth to be destroyed that severe, would be a pretty powerful one and thus could change the orbit of the Moon, since the moon is only 238,857 Miles away from Earth, it may seem alot but in astronomical distance, thats a pretty short trip.

The moon could be used as a form of "outpost" for an escapade, but as a form of new habitable planet, very far off. No atmosphere, weak gravity, even if there were liquids available it would evaporate unless an atmosphere were to be put in place, I can see how biodomes could work, but would be limiting possible resources.

Anywho, the point I was referring to is, our moon can be used as a form of outpost and connecting 'stop' toward other near planets, but as a form of lunar 'ark' it's really limited and short term.

As far as the asteroids go, they are smaller, but there are a crapload of them in one spot. Our asteroid belt is between Mars and Jupiter, one of the biggest gravitional pulls that create this belt is massive Jupiter, unabling the asteroids to create a planet of their own or dispersing around...

Between planet Earth, we have Mars and Venus, nowhere as big as Jupiter. There are also many asteroids flying about, with no destination nor orbit... there is also the chance that the moon could also become a lone 'asteroid' if the force that pushed it was stronger than the gravitational pull it held... but this is really all theoretical.

Your right, it could stay in orbit with the moon if all the conditions are met, stable and unchanged. But if the destruction of our planet and the force that created it exceeds the force of the gravitational orbit that the moon holds, well... who knows...

(dammit Im late for work^^)
