Scientists say Vallis Schrödinger and Vallis Planck—dramatic trenches near the lunar south pole—were carved in a blast that unleashed 130 times the amount of energy in Earth’s global ...

A wall of Vallis Planck appears to have partially collapsed following the valley’s formation, whereas Vallis Schrödinger has remained more intact.

Unlike the Grand Canyon, which was sculpted gradually over millions of years by the Colorado River, Vallis Schrödinger and Vallis Planck were formed in a matter of minutes. This rapid formation ...

Two such lunar canyons, Vallis Schrödinger and Vallis Planck, stretch over 270 km (168 miles) each, with depths of 2.7 km (1.7 miles) and 3.5 km (2.2 miles), respectively — comparable to Earth ...

And, they’re impressive. Vallis Schrödinger is just under 300 kilometers long, 20 km wide, and 2.7 kilometers deep. Vallis Planck has two units.

One of the canyons, called Vallis Planck, measures about 174 miles long and 2.2 miles deep. The other, called Vallis Schrödinger, is about 168 miles long and 1.7 miles deep.

Vallis Schrödinger is 168 miles (270 kilometers) long and 1.7 miles (2.7 kilometers) deep, and Vallis Planck is 174 miles (280 kilometers) long and 2.2 miles (3.5 kilometers) deep.

The rubble would have traveled at up to about 2,200 miles (3,600 km) per hour, they found. One of the canyons, called Vallis Planck, measures about 174 miles (280 km) long and 2.2 miles (3.5 km) deep.

Researches have determined that ejecta from an ancient asteroid. strike carved out the grand canyons (Vallis Schrödinger and Vallis Planck) in less than 10 minutes.
