Two Grand Canyon-size features on the far side of the moon were likely formed in about 10 minutes after an unknown object slammed into the moon 3.8 billion years ago.

The lunar canyons Vallis Schrödinger and Vallis Planck are extraordinarily deep, and scientists now know the valleys were carved by bullet-fast moon rocks.

The Earth's Grand Canyon took millions of years to carve, but the moon's grand canyons took about ten minutes.

Blue Origin's New Shepard rocket and spacecraft completed its moon-gravity mission, but the capsule appeared to have a slight hiccup on its return when one of its parachutes did not open entirely on Tuesday.

Blue Origin launched a spacecraft that can simulate lunar gravity into suborbital space during a research flight from West Texas.
