High energy streams of rock ejected from the Schrödinger impact basin carved two canyons in the lunar crust that are comparable in size to the Grand Canyon of North America. Here we use photogeologic mapping of those canyons and related impact ejecta deposits to show the trajectory of the impacting asteroid or comet, which produced an asymmetrical pattern of crater excavation and transport of ejected debris. The flow directions of that ejected debris and the speed of its subsequent impact with the lunar surface are calculated, as is the energy that carved the canyons in less than ten minutes. The study implies that most of the excavated debris was ejected away from the lunar south pole, minimizing the amount of debris that covers the > 4 billion year old units that will be explored by Artemis astronauts. The Schrödinger impact event carved two canyons on the moon comparable in size to the Grand Canyon of North America. The directions of those canyons imply little debris covers the > 4-billion-year-old units that will be explored by Artemis astronauts.
A massive crater on the dark side of the moon apparently has two 2.6km deep canyons leading off. A massive rock hit the moon at 1-2 kilometers per second, creating the huge crater. Extra debris blown off caused the canyons.
I believe it is the ‘far side of the moon’. The moon is tidally locked to the earth so we only ever see one face frome here. But it does receive light regularly as it orbits the earth.

It’s called ‘dark’ because radio signals from earth can’t reach there and visa versa
As in ‘They’ve gone dark’ (stopped all coms)
