Overview
Lunar Giant
Hertzsprung is an immense lunar impact crater, or more accurately, an impact basin, situated on the far side of the Moon. Its sheer scale surpasses that of several prominent lunar maria found on the near side, positioning it as a significant geological feature in the lunar landscape.
Geographic Context
Located beyond the western limb of the Moon, Hertzsprung resides within the peripheral region influenced by the Mare Orientale impact basin. Its position places it in a region of considerable geological interest due to its proximity to major impact structures.
Geological Epoch
The Hertzsprung formation is classified as belonging to the Nectarian period, a significant epoch in lunar history characterized by intense impact activity. This age designation provides crucial context for understanding its formation and subsequent modifications.
Location & Coordinates
Precise Positioning
Hertzsprung is precisely located at coordinates 1.37° N, 128.66° W. This position places it on the far side of the Moon, beyond the visible western limb.
Equatorial Influence
Remarkably, the Moon's equator traverses this vast formation, passing through the central basin. This unique positioning means the crater straddles the northern and southern hemispheres relative to the lunar equator.
Nearby Features
The crater is surrounded by several notable impact features. To the northeast lies the Michelson crater, while the Vavilov crater is situated across its western rim. The Lucretius crater is located to the southeast, contributing to the complex geological tapestry of the region.
Geological Structure
Rim and Modifications
The outer rim of Hertzsprung has been significantly altered by subsequent impacts and erosion. A notable feature is the Catena Lucretius, a chain of smaller craters originating from the southeastern outer rim and extending northwestward, eventually connecting to the inner basin's perimeter.
Inner Basin and Ridges
The central area of Hertzsprung is characterized by a less rugged floor compared to the outer ring. This inner basin is encircled by a distinct, circular range of ridges. Several craters, including Hertzsprung D along the eastern edge and Hertzsprung S on the western side, pierce this inner perimeter.
Gravitational Anomaly
At the heart of the Hertzsprung basin lies a significant mass concentration, or mascon. This gravitational high was initially detected through Doppler tracking data from the Lunar Prospector spacecraft, indicating a dense subsurface structure beneath the crater.
Detailed Features
Satellite Craters
Numerous smaller craters are designated as satellite craters to Hertzsprung. By convention in lunar cartography, these are identified by a letter placed on the side closest to the main Hertzsprung crater. This system aids in precise mapping and identification.
Recent Celestial Event
The Long March 3C Impact
In February 2022, it was announced that a third stage booster from the Chinese Long March 3C rocket, part of the 2014 Chang'e 5 T1 mission, was predicted to impact the lunar surface near Hertzsprung. The predicted impact occurred on March 4, 2022, at approximately 12:25:58 UTC.
Tracking Challenges
This event highlighted the difficulties in tracking small objects in deep space. The initial misidentification of the object's origin underscores the complexities involved in monitoring space debris and predicting trajectories for potential lunar impacts.
The Double Crater Discovery
In June 2022, NASA's Lunar Reconnaissance Orbiter (LRO) captured imagery of the impact site. Unusually, the impact created a distinct double-lobed crater, a phenomenon not observed with previous known rocket body impacts on the Moon. This unique feature was found near the Hertzsprung D satellite crater.
