“You don’t know that,” she said.
“It’s the best we can do. It’s not like chasing someone down to tell them their tire’s flat,” Cal said.
Chasing someone down.
“Cal…” Catherine began hesitantly. “The first Sagittarius was reconditioned and prepped as a backup, right?”
“You can’t be serious.” Cal might have been looking at her as though she were nuts, but there was the same dawning realization in his eyes that she felt herself. “You’re serious.”
“You said it. We chase them down.” Catherine wasn’t an engineer, but she could see the possibilities. “They’ve got a head start, but with a smaller crew we could push harder, take more fuel on board with us. And we’d still probably get there before the message would.” She was talking faster and faster as the idea took shape in her mind. “And even if not, if they run into trouble, they could use some backup. Someone who knows what to look for.”
“You’re saying ‘we,’ ” Aimee spoke up. “You want to go back?”
Catherine’s enthusiasm plummeted. What was she saying? That would be another six years of her life, at a minimum, gone. And that was if everything went well. And who was to say she might not be more susceptible to control a second time around? She looked at Cal, then at Aimee. “No, I don’t want to. I’m just saying that whoever goes…”
“We don’t have a crew prepped,” Cal said. Catherine could already see the wheels turning in his head. “I’m probably the only other person most prepared.” When Catherine shot him a look, he shrugged sheepishly. “I told you. I went through most of the same training as the crew. I wanted to know exactly what they’d be experiencing.”
“You can’t go by yourself, though.” Catherine reached out and took his hand. “Trust me. You don’t want to try.”
So there it was. Either Cal went alone or Catherine went with him. She laughed. “It’s probably all moot. There’s no way Lindholm will approve this.”
“I don’t know. We’ve got him over an awfully big barrel.” Cal leaned over to kiss her forehead. “I’ll let you two talk, and I’ll go see just how feasible this is. And see if I can get them to speed up that paperwork to get you out of here.”
Once he was gone, Aimee sat next to Catherine on the bunk.
“Were you really the one to figure it out?” Catherine asked.
Despite the worry in her eyes, Aimee grinned. “Yeah. When I went over to check on Cal, I wound up helping him out.”
Catherine shook her head. “You’re an amazing, brilliant woman. MIT is lucky to have you. And so am I.”
Lightly, Aimee said, “By the time you get back, maybe NASA will be lucky to have me.”
“Aimee…”
“Mom, Cal’s right. You’re the only one who can do this. It sucks. I just got you back. But this is…” Aimee gestured weakly. “This is bigger than me, or you, or our family. It’s bigger than just Cal’s crew. This is… this is world-changing stuff.” She tilted a grin up at Catherine. “I can’t think of anyone I’d rather have out there representing, like, all of humanity than my mom.”
Catherine laughed in spite of herself. “Oh, well, no pressure there.” She pulled Aimee into a hug. “We’ll see. Lindholm is gonna be a tough sell.”
“Cal will make him come around,” Aimee said confidently.
“You like him?”
“Not as much as you do, but he’s nice. Smart. You could do worse,” Aimee answered.
Catherine tightened her arms around Aimee.
The cell door opened and Cal poked his head in, and both women laughed. “Oh, that’s never a good sign,” he said. “Come on, I’m busting you out of here.”

CATHERINE SAT OUTSIDE Paul Lindholm’s office for the second time, although this time she was alone. It was hard to believe it had been two weeks since she was here last. With her release from “quarantine,” she and Cal were both reinstated, but the atmosphere was strained, especially between Cal and Aaron. Cal wouldn’t tell her what had happened there, but whatever it was, it had been big.
He was in the office with Aaron and Paul now, making his case for a third—impromptu—Sagittarius mission. Catherine had come along for moral support. Lindholm barely acknowledged her presence anymore. She had officially become a problem he wished would go away.
That was fine. She was pretty much starting to feel that way about him as well.
Suddenly the office door flew open and Cal came out with a hint of a smile. She stood up, her palms suddenly sweating. “Well?”
Cal’s smile broadened. “Wanna go for a ride?”
“Really?”
“Really. We’re cleared.”
Sagittarius III (Cal insisted on calling it Sagittarius 2.5) would go down in NASA history as the fastest mission ever to go from planning to implementation. With the ship prepped even before the mission got approval, it was only a few months before Catherine and Cal were strapped into the acceleration couches, waiting for the countdown to end.
Saying good-bye hadn’t been any easier the second time around. In some ways, it had been harder. She and Aimee had gone to Chicago together to visit Nora and Julie, and Catherine knew this time it really would be the last time she saw her mother alive. That certainty had made leaving harder. And while she’d spent as much time with Aimee as she possibly could, she still wasn’t sure it was enough.
As if he sensed her thoughts, Cal reached across the space between them and took her hand, even though both of them were wearing heavy gloves and pressure suits. “You know, my mom always used to say the surest test of a new relationship was to take a road trip together. Six years might be pushing it.”
Catherine laughed. Their words were being transmitted to Mission Control, but they’d quickly given up on trying to keep things a secret. They’d both had enough of secrets for a lifetime. “We might do better than most. Nobody can storm out during a fight.”
“I dunno; we’ve got a couple of EVA suits on board.”
“Uh, Three, this is Houston. We recommend against using EVA suits as tools in relationship management.” CAPCOM sounded equal parts amused and horrified. “That’s a major off-spec use.”
“Roger, Houston,” Catherine said, trying to keep a straight face. She glanced over at Cal and could see him grinning through his faceplate.
There was no certainty ahead of them—whether they would reach the other ship in time to stop a disaster, whether they would find a way to repair relations with an alien race, even whether they would make it back home.
But at least they were on their way.

ALTHOUGH I’VE ALWAYS been a space geek, writing Vessel took a great deal of research. NASA’s collection of websites is a treasure trove of information not just on missions but also on procedures, history, and general astronomy. Specific mission logs, in particular, gave me a real feel for how astronauts interact with one another. Also immensely helpful (and highly recommended) is Mary Roach’s book Packing for Mars: The Curious Science of Life in the Void.
Unexpectedly, a NASA press conference changed everything about this book after the first draft was complete. On February 22, 2017, NASA announced that the Spitzer Space Telescope had discovered a record-breaking seven planets within the habitable zone of a single star. All seven planets could possibly contain liquid water and be habitable. In my first draft, the destination planet was Kepler-452b, which is much farther away. I couldn’t resist updating the story with the new discovery.
