What to know about Lunar Sample Analysis

Astrobiologist Jared Landry is using Apollo lunar samples to reconstruct the atmospheric conditions of early Earth during the Archean Eon. His research suggests that the early atmosphere was significantly richer in sulfur and carbon dioxide than it is today, which may have supported the emergence of life.

What happened

Astrobiologist uses Apollo lunar samples as mirror onto early Earth Swati Mestri Scientific Editor Robert Egan Senior Editor Roll back the tape of Earth's history, and geologists and astrobiologists remain perplexed about the environmental conditions on early…

Why it matters

That's because conventional pathways for understanding Earth's history have been lost to time owing to the planet's active geology and atmospheric weathering.

Common ground

But in an ingenious new move, Jared Landry, an astrobiology Ph.D.
