Core Insights - The first batch of "lunar bricks" used for lunar construction research has successfully returned to Earth after a year-long exposure experiment in space, confirming their good condition upon inspection [1][3]. Group 1: Lunar Brick Samples - A total of 34 "lunar brick" samples, weighing approximately 100 grams, were returned, having endured extreme conditions such as space radiation and significant temperature variations over the year [3]. - The "lunar bricks" were created using simulated materials based on the composition of real lunar soil, employing three forming processes: hot pressing, electromagnetic induction sintering, and microwave sintering, achieving over three times the compressive strength of ordinary bricks [5]. Group 2: Performance Verification - The primary objective of the lunar bricks' space journey was to validate three key performance metrics: mechanical properties, thermal properties, and radiation resistance [5]. - During the space experiment, researchers conducted a series of simultaneous experiments on the ground to complement the findings from the lunar bricks' exposure in space [5].
