The Hubble Space Telescope (HST) has been used to perform systematic studies of Mars [91] and has taken the highest resolution images of Mars ever captured from Earth. [92] This telescope can produce useful images of the planet when it is at an angular distance of at least 50° from the Sun.
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Mars-1 was the first spacecraft launched to Mars in 1962, [266] but communication was lost while en route to Mars. With Mars-2 and Mars-3 in 1971–1972, information was obtained on the nature of the surface rocks and altitude profiles of the surface density of the soil, its thermal conductivity, and thermal anomalies detected on the surface of ...
When Mariner 4 flew by Mars on July 15, 1965, it captured the first images of another planet from space. But the first image of Mars ever seen on TV was different than expected.

Much of the surface of Mars is covered by a thick smooth mantle that is thought to be a mixture of ice and dust. [88] This ice-rich mantle, a few yards thick, smoothes the land. But in places it displays a bumpy texture, resembling the surface of a basketball. Because there are few craters on this mantle, the mantle is relatively young.
