Parece que é, de fato, a série Talents of the Earth de Anne McCaffrey, especificamente < em> Pegasus no espaço.
Aqui está um trecho do epílogo:
Dirk laughed. “It seems we’re always talking contracts!” But he shook his head, pointing to the monitor showing where the Bradbury had been. “You’ve proven that you can send the Bradbury somewhere—but it’ll be another forty years before even that pet SPOT of yours will see the light of that starship shining back from Capella.”
Peter’s eyes gleamed. “So you’re saying, Admiral, that until we can prove that we have lifted the Bradbury the forty-five light years to Capella, we will have a hard time revising your contract with FT&T?”
Dirk Coetzer nodded. “I’m afraid so. I know you can do it but others are going to want to see proof.”
“I told you so,” Johnny muttered to himself smugly.
“Well, how about we step over here,” Peter said, motioning the admiral toward Dash’s monitors, “so we can discuss proof more objectively.”
Dirk sighed. “Peter, I don’t think there’s much more to—” His eyes latched onto the telescope’s image of Capella’s M-5 planet. “What’s that?” the admiral pointed to the glittering speck now visible.
“That’s the Bradbury orbiting Capella,” Dash Sakai said, somehow managing to keep his voice steady as if he were reporting no more than a normal arrival.
Dirk’s jaw dropped and he turned first to Johnny, then to Peter, raising a finger accusingly. “You knew! You lifted it back in time. Why didn’t you tell me? Do you know what that means? Do you know how this will speed up our explorations? How did you do it?”
