The difference lies in a subtle tweak to the color contrast.<\/p>\n

It sure looks promising, but as you can see from the natural-color version of the image, there’s a lot that sets Mars apart<\/a> from the Atacama.<\/p>\n As the fourth planet from the Sun, Mars receives less than half of the sunlight that Earth does<\/a>, and the volume of its atmosphere is less than 1 percent of that of Earth’s atmosphere<\/a>.<\/p>\n![\"Perseverance](\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/08\/PerseverancePanorama-642x361.png\")
