The helicopter roared back to life behind them, making Helen jump. She wasn't accustomed to helicopters as a means of transportation to a paleontological dig. She glanced back to see that after depositing three moderate-sized cases on the ground, the copter was leaving. "How did you afford that thing, anyway? And you didn't bring your team?"

"I am my team, pretty much," A.J. said matter-of-factly. "Back at the labs I can get other people and use bigger equipment, but for fieldwork I just need what I brought. As for the chopper, it's a freebie. One of Ares' backers is stinking rich and offered to let me use it when I wheedled him. I'll have to arrange different transportation out, though. He only wheedled so far."

"No problem. We can give you a ride back."

Baker smiled. "I figured. And now, I'd better go back and grab those cases."

"We'll give you a hand. You're coming to help us, after all. Are you sure you aren't going to have to charge?"

"Well, there'll be a nominal fee, to make it all official. And expenses, of course. But if it's interesting, it's worth doing for publicity and professional respect. The Ares Project can always use more."

Helen nodded. The Ares Project was an attempt to send a manned mission to Mars following the approach Robert Zubrin had called "Mars Direct." It was mostly based in private enterprise and, like any major private attempt to do something scientific that seemed to have no prospects for immediate profit, it was perennially short of funds. But it was probably even shorter of the sort of "official respect" that it needed to drum up more support and financial backing.

"I think you will be more than satisfied with the challenge and the subject matter, A.J."

When they reached the cases, Helen picked up one of them. It was startlingly heavy, but Helen set her jaw and forced herself to carry it as though it wasn't any heavier than she'd expected. She wasn't sure why. Habit, she supposed, of never showing weakness in a profession that was still mostly male-dominated.
