Wallace looked interested. “Hey, computer,” he said. “Is Val right?”

There was no response.

“I guess this computer isn’t as chatty as the one we met on our trip to the stars,” I said. “But we’re definitely in the future again. For one thing, this kind of force field technology doesn’t exist yet in our time. Plus our scientists are just starting to explore the asteroid belt with robots. We’re still a long way from sending people to mine asteroids.”

The computer spoke, but it wasn’t to answer Wallace’s question. “Power usage up ten percent,” it said.

“The force field must use a lot of energy,” I guessed. “Maybe we should land so the ship can recharge.” I laughed, realizing what I’d just said. “Actually, you can’t really land on an asteroid. You have to join up with it the same way a supply ship does with the International Space Station.”

“Really?” Carlos said. “How come?”

I shrugged. “Even a big asteroid like Psyche has hardly any gravity. After all, it’s only about the size of Texas.” I grabbed The Universe again to double-check. “It says here that if you tried to pick up a car on Psyche, it would feel more like picking up a golden retriever.”

“Wow, so there’s even less gravity than on the moon?” Wallace said. “I bet I could jump like a real superhero on Psyche!”

“You could, but you might fly off into space, since the gravity there wouldn’t be enough to bring you back down,” I said. “Anyway, we should check it out. It’ll be cool to see an asteroid up close.”

“No way,” Carlos said. “I want to keep flying around. Steering this thing is a blast!”

Wallace laughed. “Yeah, like a real-life video game!”
