An animation to explain the (apparent) retrograde motion of Mars, using actual 2020 planet positions. As Mars approaches opposition, it begins a period of retrograde motion, which means it will appear to move backwards in a looping curve with respect to the background stars. This retrograde motion lasts for about 72 days, and Mars reaches its ...
Yogi Rock, analyzed by the Sojourner rover (July 4, 1997). The surface color of the planet Mars appears reddish from a distance because of rusty atmospheric dust. [1] From close up, it looks more of a butterscotch, [1] and other common surface colors include golden, brown, tan, and greenish, depending on minerals.
Mars during the 1999 opposition as seen by space telescope Mars at its 2018 opposition, with its atmosphere clouded by a global dust storm that snuffed out the solar-powered Opportunity rover The James Webb Space Telescope captured its first images and spectra of Mars on 5 September 2022. [99]
A 1962 map of Mars published by the U.S. Aeronautical Chart and Information Center, showing canals snaking through the Martian landscape.At the time, the existence of the canals was still highly controversial as no close-up pictures of Mars had been taken (until Mariner 4's flyby in 1965).
The project combined thousands of images taken by the United Arab Emirates’ Hope probe to create a detailed color mosaic of the entire planet. The spacecraft has been orbiting the red planet ...
The mystery of Mars's interior has been revealed thanks to marsquakes. Using data compiled by NASA's InSight mission that has detected hundreds of marsquakes since landing on the red planet in ...

First discovered on images from Mars Global Surveyor, they occur on steep slopes, especially on the walls of craters. Usually, each gully has a dendritic alcove at its head, a fan-shaped apron at its base, and a single thread of incised channel linking the two, giving the whole gully an hourglass shape. [ 13 ]
