” The No. 1 reason we pick all these names is to help the team keep track of what theyre finding every day,” stated Ashwin Vasavada, the Curiosity missions job researcher at NASAs Jet Propulsion Laboratory in Southern California. “Later on, we can describe the many hills and rocks by name as we discuss them and ultimately document our discoveries.”
Simply how scientists come up with the identifiers has actually progressed since the early days, 25 years back, when they used cartoon character names. Heres a better look.

Authorities Names
The distinction between an official name on Mars and an unofficial one is relatively easy: Official names have actually been authorized by a body of researchers known as the International Astronomical Union (IAU). The IAU sets standards for calling planetary features and logs the names in the Gazetteer of Planetary Nomenclature.
Craters larger than 37 miles (60 kilometers) are called for well-known researchers or science-fiction authors; smaller sized craters are named after towns with populations of less than 100,000 people. Jezero Crater, which Perseverance has actually been checking out, shares the name from a Bosnian town; Belva, an effect crater within Jezero, is called after a West Virginia town that is, in turn, named after Belva Lockwood, the suffragist who ran for president in 1884 and 1888.
More than 2,000 locations on Mars bear authorities names, but even more unofficial nicknames dot the Martian map.
Progressing Nicknames
Early Mars objectives sometimes took a whimsical path with nicknames, even using cartoon character names. “Yogi Rock,” “Casper,” and “Scooby-Doo” were amongst the unofficial names used by the team behind NASAs first rover, Sojourner, in the late 1990s.
The approach altered with the Spirit and Opportunity rovers, whose teams began using more intentional names. The names for the spots where Curiosity and Perseverance landed honor science-fiction authors Ray Bradbury and Octavia E. Butler, respectively.
Earth on Mars
Despite occasional exceptions, the Curiosity and Perseverance missions stick to labels based on terrestrial places. Before Curiosity landed in 2012, the rovers group developed a geological map of the landing location.
As now, team members recommended ideas for styles based on sites where they have worked or that they have a personal connection to, and they informally talked about which would be the most fascinating to consist of, keeping in mind that numerous names would be memorialized in future scientific papers. Once a theme is chosen, numerous names fitting into that theme are put together. That numerous are needed because the readily available names can decrease rapidly, offered that Curiosity might remain in a quadrant for a number of months.
For Curiositys latest quadrant, the rovers group chose a theme named after Roraima, the northern most state of Brazil, and for Mount Roraima, the greatest peak in the Pacaraima Mountains, situated near the border of Venezuela, Brazil, and Guyana. This marked the very first South American quadrant theme. The sulfate-enriched area Curiosity is presently checking out, with its high slopes and flat-topped hills, reminded them of the “tabletop” mountains in the Pacaraima variety.
For Perseverance, scientists picked to go with national forest styles. The rover is now checking out the Rocky Mountain quadrant and just recently drilled into rocks at a place bearing the label of Rocky Mountain National Parks “Powell Peak.”

Martian maps are full of monikers recognizing put on Earth, explorers, and even cartoon characters.
NASAs Perseverance rover is presently investigating rock outcrops together with the rim of Mars Belva Crater. Some 2,300 miles (3,700 kilometers) away, NASAs Curiosity rover recently drilled a sample at a location called “Ubajara.” The crater bears an official name; the drill place is identified by a label, for this reason the quotation marks.
Both names are amongst thousands used by NASA missions not simply to craters and hills, but also to every boulder, pebble, and rock surface area they study.
The crater bears a main name; the drill location is identified by a nickname, for this reason the quote marks.
