He published books on Mars and life on the planet, which had a great influence on the public. [61] The canali were found by other astronomers, such as Henri Joseph Perrotin and Louis Thollon using a 38 cm (15 in) refractor at the Nice Observatory in France, one of the largest telescopes of that time.

When Mariner 9 reached Mars in 1971, it and two Soviet orbiters (Mars 2 and Mars 3) found that a planet-wide dust storm was in progress. The mission controllers used the time spent waiting for the storm to clear to have the probe rendezvous with, and photograph, Phobos .
Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
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 ...

Since landing on Mars on August 5, 2012, the Curiosity rover has ascended 2,600 feet (800 meters) up the base of Mount Sharp from the floor of Gale Crater. The mountain is a central peak of the ...
Eventually, new moons were discovered also around Uranus starting in 1787 by Herschel, [23] around Neptune starting in 1846 by William Lassell [24] and around Mars in 1877 by Asaph Hall. [ 25 ] Further apparent discrepancies in the orbits of the outer planets led Percival Lowell to conclude that yet another planet, " Planet X ", must lie beyond ...
While never before discovered underneath the surface, these polygonal structures on Mars aren’t exactly a new discovery, as Universe Today explains.For example, NASA spotted them on the surface ...
