Gale is a crater, and probable dry lake, at in the northwestern part of the Aeolis quadrangle on Mars It is 154 km (96 mi) in diameter [ 1 ] and estimated to be about 3.5–3.8 billion years old. [ 3 ]
By landing in Gale crater, Curiosity was able to sample a variety of rocks because the crater dug deep into the crust, thus exposing old rocks, some of which may be about 3.6 billion years old. For many years, Mars was thought to be composed of the dark, igneous rock basalt , so this is a significant discovery.
When Gale crater became a candidate landing site, the mountain was given various labels e.g. in 2010 a NASA photo caption called it "Gale crater mound". [40] In March 2012, NASA unofficially named it "Mount Sharp", after American geologist Robert P. Sharp. [1] [41] Comparison of Mount Sharp (Aeolis Mons) to the sizes of three large mountains on ...
Deltas or fans are commonly present where a valley enters the crater floor. Particularly striking examples occur in Eberswalde Crater, Holden Crater, and in Nili Fossae region (Jezero Crater). Other large craters (e.g., Gale Crater) show finely layered, interior deposits or mounds that probably formed from sediments deposited on lake bottoms. [3]
At larger craters (like Endurance and Victoria Craters), the crater walls expose large (stratigraphic) sections of Meridiani sediments in which many sediment layers and partly embedded hematite spherules are visible. Scattered across the plain are (usually smallish) ejecta blocks of sediment from crater-forming meteorite impacts.
Yellowknife Bay is a 5-meter geologic depression located in the large impact crater known as Gale Crater. The Crater is located on Mars near the northwestern part of the Aeolis quadrangle just south of the planet's equator. The crater's central feature is a 5.5-kilometre-high (18,000 ft) mountain called Aeolis Mons, nicknamed Mount Sharp ...
It's a 1.2-kilometer crater. If you look at this and think about it, if that were to hit in a city, the city would look very, very different afterward. The estimated size of this asteroid ranges ...
On 4 November 2018, geologists presented evidence, based on studies in Gale Crater by the Curiosity rover, that there was plenty of water on early Mars. [206] [207] On 26 November 2018, Curiosity viewed a shiny object (named, "Little Colonsay") on Mars. [208] Although possibly a meteorite, further studies are planned to better understand its ...
