Octavia E. Butler Landing is the February 18, 2021, landing site of the Mars 2020 Perseverance rover within Jezero crater on planet Mars. On March 5, 2021, NASA named the site for the American science fiction author, Octavia E. Butler, who died on February 24, 2006. The Mars landing took place nearly 15 years to the day after her death.
Jezero on the edge of the Isidis basin. Jezero [a] (ICAO: JZRO) is a crater on Mars in the Syrtis Major quadrangle, [3] about 45.0 km (28.0 mi) in diameter. Thought to have once been flooded with water, the crater contains a fan-delta deposit rich in clays. [4]
It can be found in the Mars Global Surveyor, MOC narrow-angle image M02-03051, located here (MSSS) or here (by USGS) . Also in HiRISE image ESP 018368 1830 (non-map projected) and ESP 018223 1830—a stereo pair that allows 3D terrain data to be generated. Like the more famous Face on Mars, it is an example of pareidolia.
The series of valleys leading into the delta "drain" an area of approximately 4000 km 2. The surface area of the delta is 115 km 2, measuring 13 km by 11 km. The delta was discovered from images acquired by the Mars Global Surveyor in 2003, operated Malin Space Science Systems. Eberswalde delta has six lobes and is about 100 meters thick. [6]
A deposit that contains yardang was formed after several other deposits. The yardangs contain a layered deposit called "rhythmite" which was thought to be formed with regular changes in the climate. Because the layers appear harden, a damp or wet environment probably existed at the time.
Research reported in 2017 found that the amount of water needed to develop valley networks, outflow channels, and delta deposits of Mars was larger than the volume of a Martian ocean. The estimated volume of an ocean on Mars ranges from 3 meters to about 2 kilometers GEL (Global equivalent layer). This implies that a large amount of water was ...
Changes in Mars' orbit and tilt cause significant changes in the distribution of water ice from polar regions down to latitudes equivalent to Texas. During certain climate periods water vapor leaves polar ice and enters the atmosphere. The water comes back to ground at lower latitudes as deposits of frost or snow mixed generously with dust.
Colorized shaded relief map of the crater Gale. The general landing area for Curiosity on the northwestern crater floor, named Aeolis Palus, is circled.(HRSC data) Gale, named for Walter F. Gale (1865–1945), an amateur astronomer from Australia, spans 154 km (96 mi) in diameter and holds a mountain, Aeolis Mons (informally named "Mount Sharp" to pay tribute to geologist Robert P. Sharp ...
