“I’m open,” said Nyla. Cas looked up and saw that her mother was standing with knees slightly bent, ready to receive. Cas passed her the ball, and her mother trapped it and dribbled to another spot before passing it back. They continued this—laughing, dribbling, chatting, and passing—until their shadows grew long and the fat blue Sun fell behind the rim of Dao Vallis, far down-canyon from them.
Dao Vallis
They walked along the bench a bit, looking for an easy way down. Eventually, they were able to scramble down to the bottom of the channel. The surface was looser here, and composed of various sized rocks. They walked along, each kicking at rocks and stopping occasionally to pick up one that looked interesting, as humans have since they first walked the Earth. Aedan felt completely happy in a way that only happens once in a while. The novelty of walking outside with his youngest daughter had still not worn off, and he loved it.
In it
“Well,” said Nyla, “now we’re in it, huh?”
Cas smiled. “Yep,” she said. She looked around. They were alone on the surface with no shelter other than their suits and the tent strapped to the SD Rover. Cas’s smile grew broader. “This is cool,” she said.
Parting ways
Everyone stood looking at each other. Cas realized that parting on the surface like this was different than parting when they went to school and their parents went to work. They were already separate, each in their own little world maintained by their suit. They couldn’t kiss each other goodbye. Even hugging was difficult with the helmets. But they hugged nonetheless.

Offroad challenge
“Well, this looks terrifying,” said their mother, looking out the front window of the LD at the slope their father intended to descend.
“The nearest alternative adds over 120 kilometers to our route,” said Aedan, also staring at the slope. It was steep. It was uneven. It was rocky. He smiled. “It looks like fun,” he said. Nyla gave him a look but said nothing.
“Yeah!” said Cas from behind. “Do it, Dad! It’ll be epic!”
Ori joined in: “EPIC!” she hollered.

Earth and Moon
The HUD took over the front window, showing the fading blue of the sunset behind them. There was a particularly bright star shining there as well. “See that bright one there, near the horizon?” asked their mother. The sisters nodded. “That’s Earth,” she said, “and, if we’re very lucky…” she typed on her tablet and the HUD zoomed in on the bright star, splitting it into two: one bright and one smaller and very dim. “Yes, perfect,” she said. “This is using the telescope mounted on the roof. That little one is the Earth’s moon.”

Dao Vallis
They reached Dao Vallis in the early evening. The dad rolled the rover right up to the rim and stopped. The girls stared out of the window, mouths open, saying nothing. Outside that window, the world dropped away. Where their minds told them there should be something, there was nothing. And below the nothing: chaos.

LD Rover
The rover they were riding in was called an LD Rover (LD for Long Distance), and it was a beast. It had four huge wheels of compressive chain mesh that could roll over almost anything and absorb most of the shock. These were powered by an internal combustion engine operating through a sophisticated series of differentials that sent power to all wheels while allowing them each to pivot independently for steering. The engine burned methane, the easiest fuel to produce on Mars. The rover could move at up to 60 kilometers per hour on a flat surface and could crawl over almost anything it might encounter. The cabin was pressurized and roomy enough for four people to live, closely but comfortably, on extended trips. There was no airlock. Instead, the entire cabin was depressurized when the occupants wanted to go outside. It carried fuel and supplies for ten days, bulbous tanks of pressurized methane and oxygen and water riding on its back.

Paths
Everywhere you walk on Earth, you can expect to find a path or a road of some sort. Humans (modern and prehistoric), coyotes, deer, cats, rodents, snakes, ants, slugs: any living organism capable of self-mobility tends to find the easiest way to move across the land and use it, over and over. Life that moves leaves paths. There are no paths on Mars.
Or, at least, there weren’t until humans arrived. The five thousand humans of Dawn Colony had created quite a network of roads and paths around their little town. But, travel only a little way from the colony and you were well and truly in for an off-road adventure.
