Spirit Takes Snapshot of Earth 257

ControlFreal writes "On its 66th Sol on Mars, Mars Exploration Rover Spirit has obtained its first full view of crater Bonneville. In doing so, Spirit achieved its primary travel destination, as set out in its initial itinerary. Furthermore, Spirit has now travelled more than 300 meters, thereby fulfilling its minimum mission success criteria. With this, and Opportunity halfway through its primary mission, and having discovered very strong indications of a wet Martian past, NASA has truly many an astonishing interplanetary succes story! See the overview at the Mars Rover site for more details." Another reader writes "Among the 'money-shots' from the Mars rovers would have to rank the 'pale blue dot' image released today--a view looking back towards Earth. The larger image also includes the horizon and Sun, which because the Earth is seen as an inner planet closer in towards the Sun from a martian perspective, is difficult to photograph without saturation by solar glare."

    The news coverage of the exciting explots of these plucky extra-terrestrial rovers seems to have diminished. No pictures (well no original pictures) of aliens in the foreground of the Megabytes of images, no puddles, no golf-balls. Not very inspiring viewing.

    I think the realisation that the missions were not going to be highly inspirational came when it occurred to me that the first rover landed on a plain and the chosen mission was to drive over to a crater and look in while the second rover landed in a crater and its chosen mission is to take a picture of the plain just over the rim.

    Seems that getting there was the easy bit, achieving something meaningful has been a bit harder.
    • That really depends on what meaning you infer from what the rovers originally set out to accomplish. What I find inspirational is that they found bulletproof evidence that water once existed on Mars and may still exist in the form of brine.

      " The news coverage of the exciting explots of these plucky extra-terrestrial rovers seems to have diminished."

      When the press-conference of NASA was given about their revolutionairy findings, CNN was the only channel (at least here in The Netherlands) that paid attention to it. But as soon as it became clear that they had found indications for water, and NOT little green man, they immediately switched to other news. I think they only showed about 4 minutes of the press-conference. That shows how much (or lack of) interest the press and most of the public have in this mission. And I think it's sad, looking at the importance of it all.

      Like having Janet Jackson show a breast or what? The definition of "meaningful" that general public (and mass media) uses differs a lot from what intelligent people consider meaningful. Most people are idiots and sheeps, that's a fact of life. They want big explosions, deaths and sex. If NASA manages to crash their next spaceship into Paris, destroying the Eiffel Tower, I guarantee it will be a hot topic longer than anything related to the twin rovers. If a senior NASA officer (female) poses for Hustler, this will drive more traffic to nasa.gov than any photo they can shoot on Mars. That's a sad reality, but to stand on the position of the public and claim that rover missions were not really meaningful is totally wrong.

    ... I don't think this will be very important. It's a dot in the sky like any other, with just an arrow pointing to it to say that it's Earth. There's no real visceral connection there.

    I doubt any image returned by space exploration in the next few thousand years will change our perspective on things as much as the Earthrise photographs from Apollo 8. Our first view of Earth from the Moon, and it showed so much. It was large and clear enough to connect with, it was plainly Earth with oceans and continents and clouds, and it was tiny - all of human history and culture, all our achievements, in that small spot. Now that's quite a culture shock.

    But 'pale blue dot' images? It's just a dot. It might just as well be Venus for all the emotional impact I get from it. Maybe if we could see _two_ dots from Mars - Earth and Moon - then we'd get the same sense of smallness we got from the Apollo views, because that would establish identity at the gut level.

      I think that's the bigger impact... Earth as a small dot can help to show humans just exactly how insignificant our planet can be in the grand scale of the universe. Sounds like the small dot doesn't feed your ego in quite the same way as the pictures from Apollo 8 did. Well good... If you want a big emotional impact, take a look at the recent "deepest space picture ever" taken by hubble. Then count the galaxies you can see in a picture that shows an area about the size of what you would see if you looked at the sky through a drinking straw.

        It's not quite that. With Apollo 8's images, you look at it and it's Earth, obviously and plainly Earth. With the images from Mars, it's a dot. I know intellectually that it's Earth, but that's just not the same. If the picture was detailed enough that I could _see_ that it was Earth - as I mentioned, maybe if we could see the Moon beside it - then I might feel something for it.

        If I only know that it's Earth because it's in the position in the Martian sky where Earth is calculated to be, then it's just another manifestation of mathematics.

          People just don't spend the amount of time they used to looking up at the sky's wonder and glory.

          It takes a bit of experience to be able see what is dramatic. People are usually underwhelmed by what they see in a small telescope, they much less likely to be able to take in the magnificence of an unmagified image of the sky. I look at Alberio [astronomyphotos.com] through my little 90mm refractor, and it's absolutely stunning to me. However for most people it's a yawn. The only sky object that uniformly gets a "wow" is the Moon.

          If you're accustomed to looking at the sky quite a bit, you'll find that planets are dramatically different from stars: they look like little holes punched out of the sky. Once you've learned to really see planets, the idea of seeing Earth the same way will have more resonance for you.

          Mars also has kind of a creamy color when viewed from Earth; it's a bit too faint to look as dramaticall red as it is close up. Earth is a larger planet and might be a bit brighter. I wonder if the picture were in color, whether Earth might be a pale blue. A tiny sapphire glowing in a reddish dawn might be a bit more dramatic. However, the delights of naked eye and low magnification sky viewing are subtle, sometimes in hints of color, or tiny but striking arrangements. It takes a certain number of hours to be able to even perceive them.

      You make a very interesting point here, one that sent me running to look up some numbers and find a calculator. My fast crappy math seems to suggest that we could very plausibly see the moon from Mars with a decent camera.

      When the rovers were launched, Mars was about 78 million km from Earth. The average distance from Earth to the moon is roughly 400000 km. So assuming the angles are right, there would be a maximum angular separation of about s/r = 0.005 radians or 0.3 degrees - more than enough to distinguish with the naked eye. The moon is fairly large; its diameter is about 3/4 that of Mercury. Although it is not as brightly illuminated due to greater distance from the sun, my intuition is that it ought to be visible to the naked eye.

      I don't know if the Spirit or the Opportunity cameras are up to it, or if the orbital configurations are so convenient right now, but a photo of the Earth and moon like that you suggest seems entirely plausible.

        Unfortunately if you look back at the Earth you're looking towards the sun.

        While the cameras are probably good enough, the Moon isn't well lit and there's a lot of glare. It doesn't surprise me that you can't make out the Moon (although it probably is in the photo).
        • Unfortunately if you look back at the Earth you're looking towards the sun. While the cameras are probably good enough, the Moon isn't well lit and there's a lot of glare.

          What's the maximum angular separation of Earth and Sun, as seen from Mars? Venus - as we see in the night sky right now - can get a long way from the sun and become very, very prominent in the evening sky. Spirit can't see the Moon now, but perhaps in a couple of months?...

          Our big problem will probably be that the Moon is a very dark

    • I remember that broadcast. There was something visceral as they read Genesis with the picture on TV, as fuzzy as it was. Publication of the true photo only amplified it, and I still get the feeling thinking about it, decades later.

      IMHO what we need MOST at the ISS is a conference room. From what I've heard, EVERY astronaut or cosmonaut has come back to Earth with his/her world view adjusted by the experience. World leaders need to understand, that viscerally, that we all share this little island in space.

    Many of us have looked up at the night sky all our lives, some have bought or made telescopes to see even more. We've beheld some amazing and beautiful things as we gazed at the heavens. We've seen the bright stars in our sky that turned out to be separate worlds, but they still remained just little points of light as we rested comfortably on our unimaginably huge earth.

    But now we see another little dot hovering above a brightening horizon.

    That's our planet.

    Reminds one of Carl Sagan's words:

    Pale Blue Dot [planetary.org] ... Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there - on a mote of dust suspended in a sunbeam.

    The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors, so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light.

    Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.

    The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.

    It has been said that astronomy is a humbling and character building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.
    • In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.

      God will save those who embrace Him. All one has to do is answer the call. So there is a hint. In fact, there is hope.

      It does make a person reevaluate everything. It makes you wonder what things will be like in another 10,000 years. By then, maybe we'll have colonies on hundreds of planets. Our descendants will find it hard to believe that we lived on a single planet for so long.

      Somehow, I doubt it. Just a little perspective. Based on the current position of Earth and Mars:

      Distance from Earth to the closest star in Orion (HD 30652): 26.176 lightyears

      Distance from Earth to Mars: 0.0000278306 lightyears.
