The Moon may look frozen in time, but a newly discovered impact crater tells a very different story.
In this episode of vpod.ai, Mike and Susan explore the discovery of Megin Crater, a massive new lunar feature identified by NASA’s Lunar Reconnaissance Orbiter after an impact that occurred sometime between April 11 and May 22, 2024.
The crater measures roughly 728 feet across and 141 feet deep. But the most surprising discovery extends far beyond the crater itself.
Researchers detected a sprawling thermal anomaly around the impact site, where the lunar surface becomes significantly colder during the long lunar night. The episode examines how the impact’s shock wave may have disrupted and decompacted the Moon’s tightly packed regolith, creating a much larger zone of loose material around the crater.
You’ll hear about:
• How scientists discovered a new crater on a surface already covered with millions of them
• Why a large lunar impact can happen with almost no visible warning
• How NASA’s Lunar Reconnaissance Orbiter uses before-and-after imagery to spot surface changes
• What the Diviner lunar radiometer revealed about the surrounding cold zone
• Why disturbed lunar soil could create problems for astronauts, rovers, landers, and habitats
• How fresh impact sites could help engineers prepare for future Artemis missions
• Why permanent lunar infrastructure will need to account for impacts occurring miles away
The discovery offers a rare opportunity to watch lunar geology unfold almost in real time—and provides scientists with a natural laboratory for studying how major impacts alter the Moon’s surface.
As humanity moves from briefly visiting the Moon toward potentially living and working there for extended periods, understanding these hidden hazards becomes increasingly important.
