For example, rocks found higher up the mountain contained much higher levels of silica than the basaltic rocks found earlier. After further analysis, the silica-rich rocks on Mars were found to be tridymite, a mineral that is not commonly found on Earth. Opal-A, another form of silica, was also found on Mars. [169]
The history of Mars observation is about the recorded history of observation of the planet Mars. Some of the early records of Mars' observation date back to the era of the ancient Egyptian astronomers in the 2nd millennium BCE. Chinese records about the motions of Mars appeared before the founding of the Zhou dynasty (1045 BCE).
Numerous attempts [3] [4] [5] have been made over the years to determine an absolute Martian chronology (timeline) by comparing estimated impact cratering rates for Mars to those on the Moon. If the rate of impact crater formation on Mars by crater size per unit area over geologic time (the production rate or flux) is known with precision, then ...
In its ancient past, Mars likely contained many of the necessarily ingredients for microbial life to flourish on its surface. Now, a new discovery by NASA’s Perseverance rover shows a trifecta ...
Mars 1962A was a Mars flyby mission, launched on October 24, 1962, and Mars 1962B an intended first Mars lander mission, launched in late December of the same year (1962). Both failed from either breaking up as they were going into Earth orbit or having the upper stage explode in orbit during the burn to put the spacecraft into trans-Mars ...

The timeline begins at the Bronze Age, as it is difficult to give even estimates for the timing of events prior to this, such as of the discovery of counting, natural numbers and arithmetic. To avoid overlap with timeline of historic inventions , the timeline does not list examples of documentation for manufactured substances and devices unless ...
The SpaceX boss said the launch date is scheduled for when the next Earth-Mars transfer window opens in November 2026, which could see up to eight uncrewed Starhip missions to the Red Planet.
