Geologic units of Ultima Thule mapped

The geologic units of Ultima Thule were presented at the NASA press conference this week. Kirby Runyon, a New Horizons science team member from the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland differentiated hills, troughs, impact or sublimation craters or pits, streaks and hills,  and albedo features on the contact binary asteroid. The team named the largest depression “Maryland” crater.

The first map of asteroid Bennu published

Synced with the start of LPSC, DellaGiustina et al. in Nature published the first photomosaic map of the asteroid Bennu, using images from NASA’s NASA’s OSIRIS-REx spacecraft. The mosaic can also be accessed via the Osiris-Rex website. Challenges included the diamond shape of the asteroid and variable illumination conditions on the available images. Resolution is 1.6-1.8 m/pixel.

The Summer Triangle is now on the Moon

New place names have been approved within the lunar crater von Kármán where the Chinese Chang’e-4 probe landed .
Kármán, who was a Hungarian-American aerospace engineer, has craters named on both the Moon and Mars. The crater is a 180-km diameter central peak crater parly flooded by lava.
The choice of this landing site is symbolic: Qian Xuesen (钱学森, Tsien Hsue-shen), whose name is associated with China’s Space Program, was a student of Kármán when he studied and worked in the USA. He was deported from the USA in 1955 and after returning to China he participated in the initiation of the Chinese missile program, in Chinese atomic and hydrogen bomb tests and his reseach was used as a basis for the Long March rocket.
Now, as the Chinese Chang’e-4 probe landed in this crater, IAU officially approved Chinese-origin names for five sites. The names are based on the folk tale “The Cowherd and the Weaver Girl”.  While European nations named planetary features after ancient Greco-Roman mythology, Chinese-given names stem from ancient Chinese folktales. Both European and Chinese stories originate from the about 2600-2700 years ago and both are also associated with the names of celestial objects. These are the roots of celestial stories, in both cultures.

The names are:

Landing site – Statio Tianhe:  Tianhe is the ancient Chinese name for the Milky Way.

Three simple craters form a triangle around the landing site. They are named after characters in the tale that also formed an ancient Chinese constellation, the same three stars as the western culture’s “Summer Triangle”. The celestial shape is reflected in the lunar “triangle” of craters.

Zhinyu 织女 (the Chinese name corresponds to the star Vega)
Hegu 河鼓 (Chinese constellation in Aquila: Altair 河鼓二 and two adjacent stars)
Tianjin 津 (Corresponds to a Chinese constellation at the tail of Cygnus where less stars are visible. Taking the analog of the Milky Way as a river, this is a shallow part of the Milky Way, near Deneb 天津四)

The name “Mons Tai” 泰山 is assigned to the central peak of the crater Von Kármán. It is named after a mountain in Shandong, China, which is considered one of the “Five Sacred Mountains in China”.  There was a poem written by Du Fu 杜甫 (also commemorated on Mercury) about this mountain, originally composed of lines of 5 Chinese characters:

A View of Taishan

  What shall I say of the Great Peak? —
  The ancient dukedoms are everywhere green,
  Inspired and stirred by the breath of creation,
  With the Twin Forces balancing day and night
  …I bare my breast toward opening clouds,
  I strain my sight after birds flying home.
  When shall I reach the top and hold
  All mountains in a single glance?

Mons Tai is the second central peak in the Solar System to be named, the first being Aeolis Mons on Mars, at the Curisity working area. This name, “Aeolis Mons”, is almost never used by American scientists who call it Mount Sharp named after R.P. Sharp, an American planetary geomorphologist.

The naming is in accordance with the new (2017) IAU WGPSN rule according to which groups of smaller features within a larger named feature shall be named so that the names bear a mnemonic relationship to the given name of the larger feature.

As per IAU rules, only the Roman-character names are considered official. There is a growing number of names of Chinese origin in the IAU nomenclature, however, these non-roman forms are not even noted in the Planetary Gazetteer.
We are grateful for Jingming for the contribution to this article.

Report on the Commission Meeting 2018

We have held a commission meeting during the EPSC 2018 in Berlin, Germany. The topics covered were the followings: 

  • Search for publication tools to make ICA CPC publications more visible and more referenced (reviews, blogs, link to publication platforms like sciencedirect.com, Wikipedia presence, contact potential educators directly (via mailing list) to call attention to available publications related to planetary cartography and to encourage them to use it).
  • Chair change: current chair proposes A. Nass (DLR). National ICA member (Deutsche Gesellschaft für Kartographie) will be contact to propose A. Nass as next commission chair at General Assembly in Tokyo.  “The General Assembly shall, at the same time, approve terms of reference for that Commission.”
  • Standardization of map making and archiving in Europe: discussion on a ’standard’ map production  process (on European level) to ensure compatibility in creation and archiving
  • Archive for planetary mapping results is needed.  For this purpose a method has to be compiled that enables an efficient and sustainable search for cartographic products (analogue and digital). Archive should include and base on already existing map database.     
  • Reviewing the quality of planetary maps (outside USGS mapping program) is a problem: we could form a group of volunteer reviewers who would help finalizing planetary maps
  • Children’s map series: continue and focus more on age group peculiarities: focus groups / tests with maps, including “reverse side” photomap, and variants, asking their interpretation
  • Next commission meeting in Tokyo 2019
  • ICC 2019, Tokyo: Commission abstract (poster) about the book (in preparation).

2017 in Review 4: New Planetary Base Maps

Planetary Base Maps as visualizations reaching to a broad audience are a basis images used by scientists for their cartographic work. In 2017 we had some new essential base maps published for Pluto, Ceres and Mimas.

Pluto Global Color Map

The color mosaic of Pluto is created from images taken by Long-Range Reconnaissance Imager (LORRI) and the Multispectral Visible Imaging Camera (MVIC) on New Horizons that flew by the dwarf planet in 2015. It is, for now, the most detailed mosaic of Pluto reaching a resolution of 300 meters per pixel.

Uncontrolled Mosaic of Ceres

by Th. Roatsch, E. Kersten, K.-D. Matz, F. Preusker, F. Scholten, R. Jaumann, C.A. Raymond, C.T. Russell

Full atlas of Ceres in a resolution about 35 meters per pixel with 62 sheets was released this year. Photos were taken between December 16, 2015, and August 8, 2016, by the Framing Camera from the Dawn mission. This is an impressive visualization of the dwarf planet, which will surely be the base for future maps.

The Mimas Atlas

by Roatsch, T., Kersten, E., Hoffmeister, A., Wahlisch, M.

Small Saturn’s moon Mimas got complete visual image thanks to Cassini spacecraft. The CICLOPS (Cassini Imaging Central Laboratory for Operations) team have released full mosaic and cartographic sheet version of the maps. These images are an update to the previous work from 2010 showing us the moon with an image scale of 216.2 meters per pixel.

Maps of Mercury

by atlas-v7x (DeviantArt)  (New Zealand)

This series of Mercury maps show Mercury as no one has seen it before. These maps use MESSENGER topographic and color albedo data alone and combined. Nomenclature is dual, blue names are albedo features, white ones are topographic.

The Planet Venus / Venus – Map of Craters

by atlas-v7x (DeviantArt) (New Zealand)

Generic map of Venus, based on old Magellan radar altimeter data, with a fresh, terrestrial look. The Venus crater map looks as if it was taken from a School Atlas. Very Earth-like colors of very alien world with a random distribution of impact craters symbolized with little suns, otherwise to small to show up at this scale.
