A few days ago, NASA’s Mars Rover Curiosity tweeted its first shot of Earth taken from the surface of Mars, i. e. about 99 million miles (160 million kilometers) away from our home planet. Our planet Earth is just a tiny dot in the night sky, the brightest point of light above the Martian horizon. Below it there’s our moon, which isn’t clearly visible in the picture but would be clearly visible to a human eye.
The image was captured on January 31st, or the rover’s 529th Martian day of work on the Red Planet, just about 80 minutes after sunset. The image then had to be processed to remove the undesirable effects of cosmic rays. Seeing ourselves as a tiny dot in the sky really puts things in a different perspective, doesn’t it?
