I believe in the free speech that liberals used to believe in, the economic freedom that conservatives used to believe in, and the personal freedom that America used to believe in.

Picture Of The Day: Earth And Moon As Seen From Mars

by @ 11:20 am on March 4, 2008. Filed under Science, Space Exploration

The High Resolution Imaging Science Experiment (HiRISE) camera would make a great backyard telescope for viewing Mars, and we can also use it at Mars to view other planets. This is an image of Earth and the moon, acquired on October 3, 2007, by the HiRISE camera on NASA’s Mars Reconnaissance Orbiter.

At the time the image was taken, Earth was 142 million kilometers (88 million miles) from Mars, giving the HiRISE image a scale of 142 kilometers (88 miles) per pixel, an Earth diameter of about 90 pixels and a moon diameter of 24 pixels. The phase angle is 98 degrees, which means that less than half of the disk of the Earth and the disk of the moon have direct illumination. We could image Earth and moon at full disk illumination only when they are on the opposite side of the sun from Mars, but then the range would be much greater and the image would show less detail.

    Shadow Merchant Good one! However, I thought the line was “It’s turtles all the way down!”

  10. Sweet!

    I can’t make out Obama’s halo, though.

  11. Mickey Segal says:

    It is worth pointing out that the moon is 30 earth diameters from the earth, though it can appear to be less depending on the angle of the photo.

  12. Little Nemo says:

    Better take care of that tiny blue sphere. We’re not quite ready to move camp yet.

  13. Raymond says:

    I am stealing this for my blog.

    Why can Mars see Earth well … but Mars from Earth looks like a tiny star?

    If you squint you can just make out the canals…

  17. stump says:

    One can see the Earth so well in this picture because this picture is taken through a telescope.

  18. Gordon says:

    I wonder what the view would look like to the naked eye? Would it be a bright planet like we would see Venus?

  19. CCG says:

    This is terrific. Great photo, I am digging it.

  20. Suzanne says:

    I am in agreement with “Little Nemo” We are not ready to make the changes necessary to save our planet much less our own selves.

    Picture of the day: The Earth and the Moon, as seen from Mars. Wow. This brought tears to my eye in a “pale blue dot” sort of way. Imagine all the crap stuff going on here, and it is all contained on that little ball……

  22. [...] in this lifetime, anyway. Earth and the moon – but seen from another planet. This entry was written by RichieD and posted on March 6, 2008 at 6:24 am and filed under B.S.. [...]

  23. You are not alone.

  24. Kevin says:

    Ah, retarded people make life more interesting…we can see Earth and the Moon better from Mars because Mars is closer. Heh he…its true.

    I feel so small!
