Eastman (crater)
crater on Mercury

Eastman is a crater on Mercury first seen by MESSENGER during the mission's first Mercury flyby. Eastman exhibits some features characteristic of a fresh, relatively young crater. The walls of Eastman have clearly visible terraces, and the central peak structure is well preserved. Eastman is located near Xiao Zhao crater.
It is named for Charles Eastman (Santee Dakota), known as one of the first Native American to graduate from an American medical school, Boston University, and to be licensed as a doctor. He worked on Sioux reservations in South Dakota, where he met and married Elaine Goodale from Massachusetts, who headed BIA schools. They had several children together. In later life he became known as an important author of the Native American culture, publishing nine books about his Santee Sioux childhood.

“Eastman (crater)” is worth following because a concise public description often conceals a longer documentary argument. Here, Eastman, crater and Mercury provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 20, 2026. The linked authority identifier is Q5330774. Authority coordinates are 9.603, -234.301. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
