Grand Canyons on Moon Were Made in a Matter of Minutes

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 lunar far side. That's good news for scientists and NASA, which is looking to land astronauts at the south pole on the near,
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.
Grand Canyons on the Moon Were Made in a Matter of Minutes
Scientists proposed an explanation for the formation of Vallis Schrödinger and Vallis Planck near the lunar south pole, which are each about the size of Earth’s Grand Canyon.
10 Minutes of Violence Gave The Moon Its Very Own 'Grand Canyons'
Now, scientists believe that they have figured it out. Two huge canyons scored into the surface of the Moon were created in the wake of a giant impact – and, in stark and jaw-dropping contrast to the Grand Canyon, their creation could have taken less than 10 minutes.
The moon's grand canyons were carved in the blink of an eye
Even though these particular lunar craters aren't visible from your backyard, Kring says there are similar, but smaller canyons on the near side of the moon that's visible in the night sky. These radiate out from the bright spot that is Tycho Crater.
