    Default Venus rover possible? Terraforming 2 planets at once?



    I have always been interested in Venus just as much as Mars, but never see too many topics about Venus. Do you think it would be beneficial or fesible to send a rover to Venus? I know the average temperature is 872 F, but I feel with the technology today we could defintely build something.

    Another thing I think we could discuss is terraforming, I know this may be consider pseudo science but i feel is very interesting. I think it would be possible to take carbon dioxide from Venus atmosphere and transfer it to Mars, and terraforming two planets at once. Also crashing comets into Venus could re introduce water to the planet.

    I read somewhere that some scientist think Venus was once a lush jungle and the greenhouse gas got way out of control and turned it into what it is today, do you think this is possible?

    This may have been discussed before so I apologize, also if my ideas are way out there let me know, I am no scientist.

    Let me here your ideas,

    Thanks,

    Goodin

    I don't think we could build a machine to survive Venus's acid and corrosive atmosphere. As far as transferring atmospheric gases from one planet to another, it would be expensive to have rockets take off from the planet bearing payload, and especially problematic is the need to refuel. It would require less energy to find the required materials floating in space as frozen chunks, out past the ice line, and push them into the planet. We could choose composites that would neutralize such things as sulfuric acid found in Venus's clouds. Pure oxygen is highly combustible and will explode, so oxygen comets would need some problem solving before sending them into an atmosphere at high speed or they may blow away existing atmosphere. Also, once oxygen combusts, it is no longer oxygen but becomes locked away in carbon.
    If we wait a little while for the science, we will be able to create matter. Since the discoveries of the Higgs boson, the "god particle" and primordial material of the universe coupled with the soon to be understood process of quantum physics by which matter is constantly created and destroyed, we will soon be able to manufacture the required materials from the (not-so) emptiness of space. Also scientists have successfully transported photon particles from one location to another. We will soon be able to set up sending/receiving stations on other worlds, and "beam" what materials, gases, elements we feel necessary to make a planet liveable. We would also be able to temporarily "beam" human over and back wearing protective gear, and begin installing machinery for robotic tasks.
    The undertaking would no doubt be powered by solar, collected by solar panels in space, with energy "beamed" or transmitted directly to transformer stations all over the galaxy. By then, we will probably have humans exploring the fringes of the galaxy and beyond.
    Awesome idea to keep Venus in the loop. We shouldn't leave by the way-side, those possibilities that in the past haven't been possible.

    Wow awesome reponse! I did not expect one so vivid and full of information. That would be insane to be able to create whatever materials we need. Also yes I love Venus and try to keep it in the loop. I feel many people pass it up when its our cosmic twin. I feel that in time Venus would be more like Earth than Mars would be. Mars could be made like Earth but its mass is to low, I read somewhere that a extended stay on Mars could cause a human to lose muslce mass as your weight there is far less.

    You're welcome and pleased to meet you.
    We could make Mars more massive by pumping heavy material into it's core and adding back its oceans. But humans are pretty active, and already experiment with building more muscle than necessary (body builders) although they make a career out it and that takes most of their time. Conversely, humans could work in rotation on less massive planets if we achieve teleportation. Since Mars lacks tectonic movement in it's geology and therefore is not self renewing, we would have to establish stations that constantly pump the required atmosphere and water back into it to compensate for what escapes into space. We may even be able to recover the thin wisps of material that gets blown off from solar winds.

    The Russians sent a lander there quite a while back (1975). Here is a link That Che posted previously. Apparently this wasn't highly publicized at the time.

    Edit: Mars doesn't have a magnetic field to protect an atmosphere from the solar wind. So any attempt to create an atmosphere would be soon removed.

    Getting electronics to survive those temperatures is extremely difficult and expensive. I remember reading about development of the A-12 spy plane (prototype of the more famous SR-71) in the early 1960s and the trouble the engineers had trying to make electronics and wiring that would survive the 400-degree (C) temperatures that it generated in flight. That aircraft is still considered state of the art today.

    Add to the temperature the corrosiveness of the atmosphere, and it is a major technological challenge. It is amazing that the Soviet landers survived for even a few minutes.

    Ive read that Venus doesnt have a magnetic field either, or if it does that it is highly unactive. So how does this planet hang on to its atmosphere?

    It does have a field created by the dense atmosphere or it certainly wouldn't have any atmosphere. Another link shows the magnetic field as weak but the electrical current in the dense atmosphere also fends off the solar wind.

    Nice links, so do you see it more plausible if one were to try and terraform a planet to terraform Venus over Mars? Also found this link, its a bit old but was a really good read

    I didn't know there was a successful landing on Venus, I didn't know the attempt was made for one. I thought we got a few pictures on the way down and that was about it, and the probe dissolved as anticipated. Really cool seeing pictures taken from the surface of Venus!
