      Imagine after 5000 years, humans find a rover out of nowhere in some remote martian land

    2. They are Martian screws. There is not the slightest doubt nor the slightest certainty. As if a conical cylinder had survived above the rest of the materials of the past Martian society… that of things that must be read…

    3. One and a half billion years ago, while orbiting the solar system, we got very drunk and threw out a lot of unnecessary metal from our lathe shop. Delete this photo immediately, or we’ll lose our bonus.

    4. This looks like one of those blender projects where someone inserts a random shape in a fully produced scene to make it “interesting”

    5. [Here](https://i.imgur.com/D5sqG66.jpeg) is a higher-quality and less-cropped version of this image. [Here](https://mars.nasa.gov/raw_images/1102094/) is the source. Per there:

      Also:

      > Based on the image context and proximity to the rover, **the object is about 6-8mm in diameter**. It is roughly the size of a M8x20 bolt.

      > That’s a 100mm focal length lens with a 5 degree FOV at about 2-3m away. The object is 40pixels with at the circular end in a 1328 pixel wide image. When you do the math:

      > 40 pixels / 1328 pixels * 5 degrees = 0.15 deg.

      > At 3m away (based on the context of the image) it is sin(0.15 degrees) * 3 meters = 7.85mm. Even at 5m away it would be about 13mm in diameter. It is a very small object.

      **Edit:** [This](https://i.imgur.com/T9hAurI.jpeg) is the only other image of this that I could find. [Here](https://mars.nasa.gov/raw_images/1108576/?site=msl) is the source.

    6. Remember the ‘face on mars’ that almost created a whole religion until they got another view that showed it was just a trick of light?
