The Mars Express orbiter has been circling the fourth rock from the Sun for 10 years now, taking thousands of observations. Bill Dunford collected quite a few of those images and created this jaw-dropping mosaic of the south pole of Mars. It’s not quite what the eye would see; what’s shown as red is actually near infrared, invisible to us but easily seen by the camera on the spacecraft. Kilometers-thick water ice covers the pole, capped itself by a layer of carbon dioxide ice a few meters thick. That is mixed with the rusty dust eternally blowing in the Martian winds, creating what looks more like something you’d order at a coffee shop rather than the frigid nether regions of a nearby world.
