      Absolutely. It skimmed the atmosphere of Mars and bounced off and then travelled to Earth at a substantial fraction of the speed of light, to miss Earth by a few Earth radii. Rocket Scientists call this "Vogon pin-ball." It's one of those geeky jokes.

        joke? immanuel velikovsky [knowledge.co.uk] has made himself quite a reputation positing such events. calling himself a "scientist" he's claimed that venus was "ejected" from jupiter 3500 or so years ago whereupon it cruised around the solar system with a whole bunch of near misses of larger bodies before settling into its current orbit.

        the majority of his "proof" for all this are biblical stories about astrological events. for instance, velikovsky posits that the friction of venus passing closeby earth raised the surface temperature of this planet " sufficient to make the vermin of the earth propagate at a very feverish rate" thus resulting in the plagues in exodus. that's just a sample.

        wildly improbable to say the least - but velikovsky has managed to sell millions of books to the heroically undereducated public flogging this theory. a nutbar... but a rich nutbar.

        right. sensical talk about velikovsky can be had here [skepdic.com].

          And that purpose is to challenge the basic assumptions we've made about the universe and how it behaves.
          I'm not saying that anyone should junk the work that we've been building on since the Greeks through Galileo, Kepler and the like up till today.
          But when someone comes along like him I think that instead of outright dismissal, it's helpful and healthy to re-examine and re-articulate those assumptions.
          When speculative and sensational shows like the Fox "alien autopsy" and "faked moon landing" appear, it's a perfect time to re-explain that there hasn't been a single verifiable piece of evidence that UFOs are actually alien spacecraft, and that we DID go to the moon, and went there after creating an amazing space launch infrastructure in a very short time.
          Somewhat tangenitally, I sincerely believe we need heretics in any field to shake up orthodoxies and make people think a bit, even about how the basic assumptions came to be.

              Problem: The Laser Reflectors left behind by the Apollo missions.

              Scientists have been bouncing lasers off of them since the lunar landings, scientists all around the world. So either:

              A. The USA did manage to send men to the moon.

              B. The USA has a vast conspiracy organized encompassing a significant percentage of the international scientific community.

              C. The USA engaged in a huge cover-up; filming fake lunar missions somewhere, while sending a half dozen robots to moon, to plant the reflectors. All (almost, except for 13) of which worked flawlessly, and has maintained a significant cover-up of the filming.

              Regardless, I think it's clear that NASA at the very least sent significant amounts of stuff to the moon. This plus the HUGE amount of internally consistent data from the missions, some of which can/has been verified independently contributes to a high probability that the moon missions really happened.

              • I don't believe for one second the landings were faked, and all the arguments they were faked are scientifically illiterate.

                but... how are the laser reflectors evidence for manned landings? Couldn't they have been placed by a robot?
                • That would be point C in the grandparent post then.

                  Putting together a robotic mission that could emplace laser reflectors and return samples of lunar regolith would have been as technically challenging in the 60s as sending a manned mission. Automation and/or remote operation were very primitive back then.

                  The technical problems would have been different challenges of course, but still bloody awkward; plus the technology and engineering spin-offs from Apollo would have been very different.

      Freeman Dyson (Freeman Dyson!) had no trouble believing in the Ringworld

      believing in what sense? That one had been observed? I don't think so.

      That it could be built? You'll need nearly Jupiter's mass of a substance with the same tensile strength as an atomic nucleus. In sort, not known to our physical theories (I'll stop just short of saying it's impossible). And then to spin the thing up to 1 gravity, you'll need the amount of energy that our sun puts out in 1000 years. In short, extremely difficult. Even then it's unstable.

      His concept of the "Dyson Sphere" was very different from the SF concept of "a solid shell around the sun". He merely observed that the end-point of putting stuff in space to soak up the sunlight, is that all the sunlight is soaked up by millions upon millions of things, and all that gets out is the waste heat.

    As detailed in the initial NASA article the streaking was actually the result of a 15 second exposure of the sensor. It is likely that the actual object appeared as a bright moving dot against a dark sky. The length of the streak and exposure time gives NASA an estimate of speed for various theories based on the angle covered across the sensor in that 15 seconds. The data doesn't rule out a Viking orbiter but does rule out all other orbiters.

    Likely origin of the "UFO" - Earth. Cool, there's finally real evidence that the UFO sighted is actually from another planet. Unfortunately if it's true then it would really be an identified flying object, not an unidentified one.

    ripped from Jokedump
    When NASA was preparing for the Apollo Project, it took the astronauts to a Navajo reservation in Arizona for training. One day, a Navajo elder and his son came across the space crew walking among the rocks. The elder, who spoke only Navajo, asked a question. His son translated for the NASA people:
    "What are these guys in the big suits doing?" One of the astronauts said
    that they were practicing for a trip to the moon. When his son relayed this comment the Navajo elder got all excited and asked if it would be possible to give to the astronauts a message to deliver to the moon.
    Recognizing a promotional opportunity when he saw one, a NASA official accompanying the astronauts said, "Why certainly!" and told an underling to get a tape recorder. The Navajo elder's comments into the microphone were brief. The NASA official asked the son if he would translate what his father had said. The son listened to the recording and laughed uproariously. But he refused to translate.
    So the NASA people took the tape to a nearby Navajo village and played it for other members of the tribe. They too laughed long and loudly but also refused to translate the elder's message to the moon.
    Finally, an official government translator was summoned. After he finally stopped laughing the translator relayed the message: "Watch out for these assholes - they have come to steal your land."

    Although orbital mechanics is not my specialty, I think NASA should be able to calculate an approximate orbit and take more images to see if it might be Viking 2.

    The height of the streak in the image, the distance away and the orientation of camera will give the position. Put this with velocity to get the orbit. So, we just need to know distance away and velocity. The length of the streak plus the exposure time can give them a equation of velocity vs. distance away. Orbital mechanics gives another equation for velocity vs. height. Use these 2 equations to solve for the orbit, assuming the object is in orbit and not just passing by. NASA knows the orbital elements of Viking 2 when it was in use and can use these to see if the calculated orbit is reasonable.

    Then using the orbit, calculate times the object would be visible to either rover and make some long exposures at the predicted times to look for it again. The only problem I can see is that the measurement error might be too much to make accurate predictions about future approaches.

    This assumes NASA cares whether it's Viking 2.

    The odds against this kind of coincidence must be staggering. Any math geniuses want to take a stab at it? We could estimate how often the half-dozen (?) satellites around mars would pass through that particular section of the sky, and we know roughly how many photos the rovers take in a given day...
