Gale is a crater, and probable dry lake, at 5.4°S 137.8°E in the northwestern part of the Aeolis quadrangle on Mars. It is 154 km (96 mi) in diameter and estimated to be about 3.5–3.8 billion years old. The crater was named after Walter Frederick Gale, an amateur astronomer from Sydney, Australia, who observed Mars in the late 19th century. Aeolis Mons is a mountain in the center of Gale and rises 5.5 km (18,000 ft) high. Aeolis Palus is the plain between the northern wall of Gale and the northern foothills of Aeolis Mons. Peace Vallis, a nearby outflow channel, 'flows' down from the hills to the Aeolis Palus below and seems to have been carved by flowing water. Several lines of evidence suggest that a lake existed inside Gale shortly after the formation of the crater.
The Aeolis quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Aeolis quadrangle is also referred to as MC-23 . The Aeolis quadrangle covers 180° to 225° W and 0° to 30° south on Mars, and contains parts of the regions Elysium Planitia and Terra Cimmeria. A small part of the Medusae Fossae Formation lies in this quadrangle.
The composition of Mars covers the branch of the geology of Mars that describes the make-up of the planet Mars.
Mount Sharp, officially Aeolis Mons, is a mountain on Mars. It forms the central peak within Gale crater and is located around 5.08°S 137.85°E, rising 5.5 km (18,000 ft) high from the valley floor. Its ID in the United States Geological Survey's Gazetteer of Planetary Nomenclature is 15000.
Aeolis Palus is a plain between the northern wall of Gale crater and the northern foothills of Aeolis Mons on Mars. It is located at 4.47°S 137.42°E.
Curiosity is a car-sized Mars rover designed to explore the Gale crater on Mars as part of NASA's Mars Science Laboratory (MSL) mission. Curiosity was launched from Cape Canaveral (CCAFS) on 26 November 2011, at 15:02:00 UTC and landed on Aeolis Palus inside Gale crater on Mars on 6 August 2012, 05:17:57 UTC. The Bradbury Landing site was less than 2.4 km (1.5 mi) from the center of the rover's touchdown target after a 560 million km (350 million mi) journey.
The Dynamic Albedo of Neutrons (DAN) instrument is an experiment mounted on the Mars Science Laboratory'sCuriosity rover. It is a pulsed sealed-tube neutron source and detector used to measure hydrogen or ice and water at or near the Martian surface. The instrument consists of the detector element (DE) and a 14.1 MeV pulsing neutron generator (PNG). The die-away time of neutrons is measured by the DE after each neutron pulse from the PNG. DAN was provided by the Russian Federal Space Agency, funded by Russia and is under the leadership of Principal Investigator Igor Mitrofanov.
The Mars Science Laboratory and its rover, Curiosity, were launched from Earth on November 26, 2011. As of April 15, 2022, Curiosity has been on the planet Mars for 3445 sols since landing on August 5, 2012. (See Current status.)
N165 is a rock on the surface of Aeolis Palus in Gale Crater on the planet Mars near the landing site of the Curiosity rover. The "approximate" site coordinates are: 4.59°S 137.44°E. On August 19, 2012, the rock was the first target of the rover's laser instrument, ChemCam, which can analyze targets at a distance using a laser and spectrometer. A Twitter feed for the rock was created, featuring an anthropomorphized account of its experiences. Its posts include a humor themed mix of social interaction and Mars content such as "Did you know I was born in a volcano? Basalts like me come from lava. That's why we call it Olympus Mom".
Glenelg, Mars is a location on Mars near the Mars Science Laboratory landing site in Gale Crater marked by a natural intersection of three kinds of terrain.
Bradbury Landing is the 6 August 2012, landing site within Gale crater on planet Mars of the Mars Science Laboratory (MSL) Curiosity rover. On 22 August 2012 on what would have been his 92nd birthday, NASA named the site for author Ray Bradbury, who had died on 5 June 2012. The coordinates of the landing site on Mars are: 4.5895°S 137.4417°E.
Jake Matijevic is a pyramidal rock on the surface of Aeolis Palus, between Peace Vallis and Aeolis Mons, in Gale crater on the planet Mars. The approximate site coordinates are: 4.59°S 137.44°E.
Peace Vallis is an ancient stream valley on the northern rim of Gale Crater on the planet Mars. It is notable for its associated alluvial fan which lies near the Mars Science Laboratory Curiosity landing site. The valley and alluvial fan provide evidence for geologically recent fluvial activity and sustained water flow on Mars. Recent high-resolution orbital images of Peace Vallis and its watershed also suggest that at least one glacial episode affected Gale crater. All of this evidence has implications for the history of water on Mars and the planet's long-term habitability. Understanding Peace Vallis and its fan also provides geologic context for the rocks observed on the ground by the Curiosity rover.
Bathurst Inlet is a rock on the surface of Aeolis Palus, between Peace Vallis and Aeolis Mons, in Gale crater on the planet Mars. The rock was encountered by the Curiosity rover on the way from Bradbury Landing to Glenelg Intrigue on September 30, 2012 and was named after Bathurst Inlet, a deep inlet located along the northern coast of the Canadian mainland. The "approximate" site coordinates are: 4.59°S 137.44°E.
Hottah is a rock outcrop on the surface of Aeolis Palus, between Peace Vallis and Aeolis Mons, in Gale crater on the planet Mars.
Rocknest is a sand patch on the surface of Aeolis Palus, between Peace Vallis and Aeolis Mons, in Gale crater on the planet Mars. The patch was encountered by the Curiosity rover on the way from Bradbury Landing to Glenelg Intrigue on September 28, 2012. The approximate site coordinates are: 4.59°S 137.44°E.
Link is a rock outcrop on the surface of Aeolis Palus, between Peace Vallis and Aeolis Mons, in Gale crater on the planet Mars. The outcrop was encountered by the Curiosity rover on the way from Bradbury Landing to Glenelg Intrigue on September 2, 2012, and was named after a significant rock formation in the Northwest Territories of Canada. The "approximate" site coordinates are: 4.59°S 137.44°E.
Goulburn, also known as Goulburn Scour, is a rock outcrop on the surface of Aeolis Palus, between Peace Vallis and Aeolis Mons, in Gale crater on the planet Mars. The outcrop was encountered by the Curiosity rover on landing at the Bradbury Landing on August 6, 2012 and is named after a two-billion year-old sequence of rocks in Northern Canada. The "approximate" site coordinates are: 4.59°S 137.44°E.
Rocknest 3 is a rock on the surface of Aeolis Palus, between Peace Vallis and Aeolis Mons, in Gale crater on the planet Mars. The approximate site coordinates are: 4.59°S 137.44°E.
