Explanation: If you could stand on Mars, what would you see? The robotic Phoenix spacecraft that landed on Mars in 2008 recorded the above spectacular panorama. The above image is actually a digital combination of over 100 camera pointings and surveys fully 360 degrees around the busy robotic laboratory. Scrolling right will reveal the rest of the panoramic image. Visible in the image foreground are circular solar panels, various Phoenix instruments, rust coloured rocks, a trench dug by Phoenix to probe Mars' chemical composition, a vast plateau of dirt and dirt-covered ice, and, far in the distance, the dust coloured atmosphere of Mars. Phoenix landed in the far north of Mars and has used its sophisticated laboratory to search for signs that past life might have been possible. Soil analyses have confirmed the presence of ice and gave unexpected indications of perchlorate salts. Whether Martian life could have evolved around such perchlorates is an ongoing topic of research.
