Extraordinary images reveal the mysteries of Mars

From H. G. Wells’s alien invaders in The War of the Worlds to The Martian‘s abandoned astronaut, we have long been inspired by the idea that life could reside on Mars – human or otherwise. Flybys, orbiters and landers, including NASA’s Perseverance rover and its aerial sidekick, Ingenuity, have made Mars one of the best understood planets in our solar system. Now, more than ever, we are closer to answering the question: could life exist there?

Mars Reconnaissance Orbiter used its sharp-eyed HiRISE camera to photograph the Mars Exploration Rovers Spirit and Opportunity on the surface. This photo commemorates Opportunity?s arrival at the 800-meter-diameter Victoria crater on the 951st day of Opportunity?s mission. The rover is visible as a tiny speck at about 10 o?clock. ?

Mars Odyssey brought new imaging technology to Mars with its Thermal Emission Imaging System (THEMIS), which can see the surface in both day and night. In 2006 the THEMIS team began combining daytime images (which show topography in black and white) with nighttime views (which show temperature, from cold blue to warm red). In the Martian night, bedrock exposed on the flatlying Meridiani Planum and in crater rims retains heat, so is relatively warm compared to dust-covered areas. PAGE 158

A new book, Mars: Photographs from the NASA archive, celebrates the missions that have enriched our understanding of Mars and looks to a future where humans explore the Red Planet.

A camera mounted to the top deck of the Perseverance rover captured the deployment and inflation of its supersonic parachute during its descent to Mars in 2021. The red-and-white stripes both help engineers map the motions of the parachute and encode two secret messages: the geographic coordinates of the Jet Propulsion Laboratory and the lab motto ?dare mighty things.?

NASA?s Mars 2020 Perseverance rover, moments before landing in Jezero Crater, February 18, 2021. The photo was taken from the rocket-powered descent stage, which is lowering the rover to the ground on cables while hovering. At the moment of touchdown, the rover cut its cables, and the descent stage flew away to crash at a safe distance. ? NASA/JPL-Caltech PAGE 214
