Artemis Crew to Study Moon Craters as a Window into Earth's Ancient Past

NASA astronaut Chris Williams explains that the approaching Artemis II crew will closely observe the Moon's craters, which act as a preserved historical record of impacts in the Earth-Moon system. On Earth, such craters have been largely erased by geological processes like plate tectonics and weathering. The crew's unique vantage point will allow them to study features like the heavily cratered far side directly. The mission continues its preparation as it proceeds with a historic lunar flyby, watched by the world.

Key Points: Artemis Crew to Study Moon Craters for Earth's History

  • Moon craters are a historical record
  • Earth's craters erased by geology
  • Crew to get firsthand view of lunar surface
  • Artemis II en route for historic lunar flyby

Artemis crew to study moon craters for insight into Earth's past

NASA's Artemis II crew will examine lunar craters, a preserved historical record erased on Earth, during their historic flyby.

"The Moon helps us fill in the picture and tells us a unique story about our planet's past! - Chris Williams"

Washington DC, April 6

NASA Astronaut Chris Williams on Monday said that as the Artemis crew approaches the Moon, they will get a closer look at the craters on the surface, which serve as a historical record of the conditions around the Earth and Moon.

Williams said that the Earth also had seen several impacts throughout history, but plate tectonics, weathering, and volcanism have erased those.

In a post on X, he said, "As the NASA Artemis II crew approaches the Moon, they will get a firsthand view of the Moon's surface. One of the most striking (pun intended) features they will see is the craters which mark its surface, and are especially numerous on the far side, which the crew will be able to see direct. These craters are formed by impacts that have happened over the history of our Solar System and act as a sort of historical record of the conditions around the Earth and Moon."

"The Earth has had many impacts over its history that have had big consequences on our planet (just ask the dinosaurs...), but plate tectonics, weathering, and volcanism have erased many craters on the Earth, and with them, the record of this history. The Moon helps us fill in the picture and tells us a unique story about our planet's past!" he added.

Williams further said that although the Earth still has many craters, none of them are quite like the moon.

"Even so, there are still many craters on Earth, but many are often not as easily visible as those on the Moon. Some, like Manicouagan Crater in Quebec, Canada, are very readily seen from the Space Station. This crater was created over 200 million years ago, when a 5 km asteroid crashed into the Earth, and is over 70 km wide. I saw this view through the Cupola window as I was exercising and had to pause to take a picture!" he said.

NASA shared updates on how the crew is preparing for the lunar flyby tomorrow.

"No days off when you're Moonbound. Astronaut Christina H Koch continues prep for tomorrow's lunar flyby after completing her workout. Meanwhile, our entire world watches in anticipation with hope and excitement as the NASA Artemis II crew presses on toward the Moon."

Artemis II astronauts began their historic lunar fly-around to push deeper into space than even the Apollo astronauts on Saturday.

Fascinating read. While this is great science, I do hope the immense resources going into Artemis also inspire more investment in solving problems closer to home, like climate change and sustainable development. Science for humanity's benefit should be the ultimate goal.

The part about the astronaut pausing his workout to take a picture of the crater is so relatable! 😄 It's these human moments that make space exploration so inspiring for the next generation. My son is now obsessed with craters after reading this.

The comparison is brilliant. Earth's dynamic surface is always changing, while the Moon is like a frozen museum. It puts into perspective how young and active our planet is. Wishing the crew a safe and productive mission!

"Just ask the dinosaurs..." – that line hit hard! 🦕 It's a stark reminder of how vulnerable life on Earth can be. This research isn't just about the past; it's crucial for planning our future planetary defense. Jai Vigyan!

Wonderful to see human spaceflight progressing. As an Indian, I'm proud of what ISRO has achieved with Chandrayaan, but seeing crewed missions like Artemis is on another level. Hope for more international collaboration in this new era of lunar exploration.
