Detailed Notebook Page for [Lunar Base Theta]

Design a detailed notebook page for [Lunar Base Theta], featuring a stamped emblem. The emblem should include "Exploration Authorized" in bold English, shaped as a hexagon with complex geometric designs. Incorporate the word "EXPEDITION" along with a fictional date like "22 AUG 2077." In the background of the emblem, integrate a subtle outline of a futuristic moon rover. Use metallic silver or dark gray ink with gentle fading to create a realistic effect. The stamp should appear slightly misaligned, giving the impression of manual application. The notebook page should have a textured, recycled paper look with faint grid lines and cosmic-themed security watermarks embedded.
