One rock, "Bounce Rock," found sitting on the sandy plains was found to be ejecta from an impact crater. Its chemistry was different from the bedrocks. Containing mostly pyroxene and plagioclase and no olivine, it closely resembled a part, Lithology B, of the shergottite meteorite EETA 79001, a meteorite known to have come from Mars.
32 of these have names tied to the Earth and the other 10 have names connected to bodies in the Solar System. The first tables below list the terrestrial locations (excluding the entire Earth itself, taken as a whole) and the last table lists astronomical objects which the chemical elements are named after.

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]
Wollaston discovered it in samples of platinum from South America, but did not publish his results immediately. He had intended to name it after the newly discovered asteroid, Ceres, but by the time he published his results in 1804, cerium had taken that name. Wollaston named it after the more recently discovered asteroid Pallas. [112] 58 ...
The team’s analysis shows that water was present just 100 million years after the planet formed, which suggests that Mars may have been able to support life at some point in its history ...
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 ...
The dust in Gusev Crater is the same as dust all around the planet. All the dust was found to be magnetic. Moreover, Spirit found the magnetism was caused by the mineral magnetite, especially magnetite that contained the element titanium. One magnet was able to completely divert all dust hence all Martian dust is thought to be magnetic. [12]
Chemical elements are sometimes named after people, especially the synthetic elements discovered (created) after c. 1940. Very few are named after their discoverers, and only two have been named after living people: the element seaborgium was named after Glenn Seaborg , who was alive at the time of naming in 1997; [ 5 ] and in 2016 oganesson ...
