Rover radiation data poses manned Mars mission dilemma
#off topic forum
  • Yup. Sorry true believers...

    But Mars doesn't have a thick atmosphere with an ozone layer to shield out ultraviolet rays, and micro waves. Mars has no spinning metal core to create a magnetic shield to keep out cosmic rays. Mars is hit with Gamma rays and enough solar radiation to
    Sterilize the surface completely...every time the planet revolves.

    And it's been like that for over a billion years. At least the molten spinning metal core part....and the atmosphere part.

    This is covered completely about once a week on the Science Channel.

    We aren't going there anytime soon. Except in our imagination......

    And robots. And robot dogs. Because robots get lonely...and a robot dog is a robot's best friend. There...See? I still belong here.

    • Sounds like NASA is getting scared!

      Good!!!

      The Millionaire that wants a manned mission by 2020, says that NASA is BS, or making it sound worse than it is because of all the secrets on it's surface.

      If we can get there in a few weeks with new propulsion systems, then as long as adequate shielding is developed on the surface, there is not a problem.

      Astronauts stay at the ISS for 6 months at a time, and Russian astronauts, used to stay up for for 1 or more years?

      Sound like they are trying to scare potential astronauts, into thinking twice, about the mission, next they will show graphic videos of what the cancer will do or look like.

      It is good to see a rotting institution shaking in its boots!


      Curiosity may have measured these particles with adequate shielding, (they need to explain adequate, if it is a piece of gold tinfoil then it's a joke)!

      Ok, real Hubble images showing Mars thick atmosphere, (these are real Hubble images, not Photoshopped)!

      And NASA's BS images of Mars!


      Mars does have an atmostphere, but what drives it is still unknown!

  • In spite of the challenges, I still hope we get there one day

    Humanity shouldn't put all its eggs in one basket (earth).

    • Socialentry; I wish that were plausible. Can we Terra-form Mars? Yes. But it would cost many hundreds of times more than simply fixing our environmental problems here.

      And Mars has problems that will never go away. If you create an atmosphere (Over a few thousand years, but it's possible), there is no spinning iron core...no magnetic shield to keep radiation from blowing the atmosphere away, like it did before. Mars is half the size of the Earth but only a third the gravity, because there is no thick iron core. It's not enough to hold onto a thick atmosphere.

      And Mars is far enough away from the Sun that under ideal circumstances (which may have actually existed at one time) it's still on the outer edge of the orbital zone where water can stay liquid.

      We shouldn't put our eggs in one basket...unless the next nearest basket is 54.8 million miles away.

      Again (this isn't to you) all this is on the Science Channel every few days.
      It's fascinating stuff to me.

    I stayed at a Holiday Inn once so I kinda know everything about Mars.
