That image—which has been slightly color-tweaked—is above. Curiosity is the blue, almost-beetle-like object in the center: It’s about the size of an SUV. Behind it, 9-foot-wide tracks snake and curve through the landscape. You can see them enter the picture near the top, and the whole photo captures a little over a month of rover tracks. According to NASA, the rover entered the area being imaged on March 12, 2014.
The entire image is 1,200 feet wide, about a fifth of a mile.
NASA, in fact, purposefully pilots the orbiter near the rover. Like on Earth, it helps scientists to get a view of the terrain from multiple angles. The rover, too, has been taking photos of this area.
Flyby photos of this type don’t just happen on Mars. Earlier this year, the youngest satellite in the Landsat program—a long-running U.S. Geological Survey project to continuously photograph the Earth’s surface—captured an image of an earlier Landsat satellite zooming below. Unlike the stable Curiosity Rover, the Landsat craft looked, in the image, like a black smear.
