Subject: Morphometric Evaluation of Macroscopic Reticulate Structures in MAHLI Image 4750MH0009050011703493C00

Abstract

While previous studies have identified microscopic (0.15 mm) geometric grids on the Martian surface, new imagery from Sol 4750 reveals a distinct, macroscopic class of anomalies. This article presents a structural analysis of the “Huge Boxwork” formation documented in MAHLI image 4750MH0009050011703493C00. Unlike the delicate micro-lattices observed on Sol 4745, this formation exhibits massive, load-bearing walls measuring 0.5 to 1.2 mm in thickness. The scale, rigidity, and orthogonal consistency of these features suggest they are the eroding remnants of a large-scale engineered construct rather than natural mineral veins.

1. Introduction: The Scale of Engineering

The discovery of geometric anomalies on Mars has largely been confined to the microscopic regime. However, the image captured on Sol 4750 (Flickr ID: 54993232483) challenges this limitation by presenting a macroscopic grid structure. The “Huge Boxwork” does not require a microscope to identify; it is a visible, tactile feature of the rock surface. This shift in scale from “micro-texture” to “macro-structure” implies a functional differentiation in the hypothesized artificial origins—moving from “material science” (composite coatings) to “structural engineering” (walls and frames).

2. Quantitative Data

Using the specific metadata from the Mars Hand Lens Imager (MAHLI), the following morphometric constraints were established for this target:

• Focus Motor Count: 13289 (Interpolated Working Distance: ~16 cm).

• Field of View: The image covers a physical width of 7.4 cm (74 mm).

• Pixel Scale: Approximately 46 micrometers (0.046 mm) per pixel.

• Feature Dimensions:

• Wall Thickness: The “red-arrowed” ridges measure between 0.5 mm and 1.2 mm (500–1200 microns).

• Cell Size: The voids (polygonal rooms) between walls span 4 mm to 8 mm in diameter.

3. Structural Analysis: Veins vs. Walls

The primary geological counter-hypothesis for such features is “boxwork weathering,” where mineral veins (e.g., quartz or calcite) persist after the softer host rock erodes. This article argues that the Sol 4750 formation deviates from natural boxwork in three critical ways:

1. Wall Uniformity: Natural veins typically vary in width as they pinch and swell through rock fractures. The walls in this image maintain a consistent “structural” thickness (~0.8 mm average) over significant lengths.

2. Orthogonal Intersections: The grid intersections frequently form T-junctions and 90-degree corners, creating a layout reminiscent of a floor plan or reinforced mesh rather than the acute angles typical of shear fracturing.

3. Vertical Relief: The “fins” stand prominently away from the surface, indicating a material hardness significantly greater than the surrounding regolith. If these were simple mineral deposits, such high relief often leads to crumbling; the preservation of these thin, high walls suggests a material tensile strength comparable to manufactured ceramics or metal-oxides.

4. Comparison to Micro-Grids (Sol 4745 vs. Sol 4750)

A key finding of this research is the bimodal distribution of these anomalies:

• Type A (Micro-Grid): Sol 4745. Size: 0.15 mm. Likely a surface coating or material fabric.

• Type B (Macro-Grid): Sol 4750. Size: 0.8 mm. Likely a structural framework.
  The existence of two distinct, standardized scales of “boxwork” reinforces the artificial hypothesis. Nature tends to produce a continuum of sizes (fractals); engineering produces discrete, functional scales (e.g., bricks vs. beams).

5. Conclusion

The “Huge Boxwork” on Sol 4750 represents a macroscopic Technosignature. The presence of 0.8 mm thick rigid walls arranged in a 7.4 cm wide orthogonal grid provides evidence of ancient construction at a scale relatable to human engineering. These features are interpreted not as geological accidents, but as the exposed structural ribs of a larger, now-degraded artifact.
