The MESSENGER Education and Public Outreach (EPO) Team is launching a competition this week to name five impact craters on Mercury. The contest is open to all Earthlings, except for members of the mission’s EPO team. The contest runs from December 15, 2014, to January 15, 2015.

NASA’s MESSENGER spacecraft has been in orbit about Mercury since March 2011. The mission’s EPO team is led by Julie Edmonds of the Carnegie Institution for Science.

According to the International Astronomical Union (IAU) — the governing body of planetary and satellite nomenclature since 1919 — all new craters on Mercury must be named after an artist, composer, or writer who was famous for more than 50 years and has been dead for more than three years. See the current list of named Mercury craters at http://planetarynames.wr.usgs.gov/SearchResults?target=MERCURY&featureType=Crater,%20craters

The EPO team’s contest allows the public to immortalize an important person in the arts and humanities from anywhere in the world. Submissions will be accepted beginning midnight (00:00 UTC) on December 15, 2014, until January 15, 2015 (23:59 UTC). Fifteen finalist names for craters will be submitted to the International Astronomical Union (IAU) for selection of the five winners. Winning submissions will be announced by the IAU to coincide with the end of MESSENGER’s orbital operations in late March or April 2015. IAU decisions will be final.

The MESSENGER spacecraft has far surpassed expectations both in the duration of the mission and in the quality and quantity of data. The mission will end this spring as the tiny craft succumbs to gravity and impacts on Mercury. The EPO team organized the competition to celebrate the mission’s achievements.

Edmonds advises participants to first research the artist, composer, or writer under consideration before filling out the contest entry. “Once online, registrants will be asked to submit a short description of their chosen individual’s contributions to their field, as well as an authoritative source for background information,” she said.

The name cannot have any political, religious, or military significance. Nor can other features in the solar system have the same name. For example, Ansel Adams is not eligible because there is a feature on the Moon with the name Adams (even though it was not named for Ansel). Participants can check their ideas against the list of named solar system features [http://planetarynames.wr.usgs.gov] and enter the name in the “Search by Feature Name” box in the upper right corner.

“This brave little craft, not much bigger than a Volkswagen Beetle, has travelled more than 8 billion miles since 2004 — getting to the planet and then in orbit,” Edmonds said. “We would like to draw international attention to the achievements of the mission and the guiding engineers and scientists on Earth who have made the MESSENGER mission so outstandingly successful.”

The goal of MESSENGER was to take 2,500 images of the planet, but is has returned more than 250,000 images. “We now have a detailed, high-resolution map of the entire planet,” Edmonds noted. “As scientists study the incredible data returned by MESSENGER, it becomes important to give names to surface features that are of special scientific interest. Having names for landforms such as mountains, craters, and cliffs makes it easier for scientists and others to communicate.”

The Carnegie Institution for Science (http://carnegiescience.edu) is a private, nonprofit organization headquartered in Washington, D.C., with six research departments throughout the U.S. Since its founding in 1902, the Carnegie Institution has been a pioneering force in basic scientific research. Carnegie scientists are leaders in plant biology, developmental biology, astronomy, materials science, global ecology, and Earth and planetary science.

MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) is a NASA-sponsored scientific investigation of the planet Mercury and the first space mission designed to orbit the planet closest to the Sun. The MESSENGER spacecraft was launched on August 3, 2004, and entered orbit about Mercury on March 18, 2011 (UTC), to begin its primary mission — a yearlong study of its target planet. MESSENGER’s first extended mission began on March 18, 2012, and ended one year later. MESSENGER is now in a second extended mission, which is scheduled to conclude in late March or April 2015. Sean C. Solomon, the Director of Columbia University’s Lamont-Doherty Earth Observatory, leads the mission as Principal Investigator. The Johns Hopkins University Applied Physics Laboratory built and operates the MESSENGER spacecraft and manages this Discovery-class mission for NASA.
