Asteroid impact on moon blasted two grand canyons in 10 minutes
The Grand Canyon in Arizona is one of Earth's natural wonders, carved out over millions of years by the gradual erosion power of the Colorado River. Close to the moon's south pole are two canyons each comparable in size to the Grand Canyon that were born in a much different process.
The moon's grand canyons were carved in the blink of an eye
The Earth's Grand Canyon took millions of years to carve, but the moon's grand canyons took about ten minutes.
Two giant valleys on the Moon, each the size of the Grand Canyon, formed in 10 minutes: study

They were dug out by debris sent violently aloft when an asteroid or comet struck the lunar surface 3.8 billion years ago.
How an ancient asteroid strike carved out 2 grand canyons on the moon
New research shows that when an asteroid slammed into the moon billions of years ago, it carved out a pair of grand canyons on the far side
Bullet-fast moon rocks carved 2 lunar gorges deeper than the Grand Canyon
The lunar canyons Vallis Schrödinger and Vallis Planck are extraordinarily deep, and scientists now know the valleys were carved by bullet-fast moon rocks.
Why it’s good for NASA that an asteroid carved out 2 grand canyons on the moon
