The landing site for China's complex Chang'e 5 moon sample and return mission now has a name: Statio Tianchuan.
Statio means a post or station in Latin and is also used in the formal name for NASA's Apollo 11 landing site, Statio Tranquillitatis; and Statio Tianhe, China's Chang’e 4 landing site on the far side of the moon. Tianchuan comes from a Chinese constellation name, which means ship sailing in the Milky Way. Tianchuan consists of nine bright stars in eastern part of the constellation Perseus.
The name was approved in May by the International Astronomical Union (IAU), which oversees all formal names for features in space and on solar system bodies.
Chang'e 5 landed at 43.06 degrees north, 51.92 degrees west on the lunar surface near Mons Rümker in Oceanus Procellarum, located in the northwest of the near side of the moon, on Dec. 1, 2020. The spacecraft collected 3.82 lbs. (1.73 kilograms) of lunar sample material and delivered those samples to Earth on Dec. 16.
Near this landing site are a group of 7 topographical features that have also now received names. These include the peaks Mons Hua (opens in new tab) and Mons Heng (opens in new tab) and craters Pei Xiu (opens in new tab), Shen Kuo, Liu Hui (opens in new tab), Song Yingxing (opens in new tab) and Xu Guangqi (opens in new tab).
Mons Hua and Mons Heng are named after mountains in China, with mons being Latin for mountain. The craters are named for a number of Chinese astronomers, scientists and mathematicians from the past 1,800 years.
These features are all marked in a map in the Gazetteer of Planetary Nomenclature.
Meanwhile on Earth, the Chang'e 5 samples are set to be analyzed. A portion of the samples have been made available (opens in new tab) for loan to institutions in China, with international applications also to be considered.
And the Chang'e 5 orbiter which helped deliver the samples is now carrying out tests and returning eerie images from a point in space known as Sun-Earth Lagrange point 1.
