But the margins don't help; it is soon clear that they are in big trouble. Earth will pass too far ahead of them on her next orbit, they don't have the acceleration to catch up with her before they cross her path. They can carry out an ullage maneuver, they can kill enough velocity to let Earth catch them on the second go-by; but that would take an extra year and their life-support would be long gone. The grim question of whether they have enough. to enable a single man to wait it out pushes into Lorimer's mind. He pushes it back; that one is for Dave.
There is a final possibility: Venus will approach their trajectory three months hence and they may be able to gain velocity by swinging by it. They go to work on that.
Meanwhile Earth is steadily drawing away from them and so- is Gloria, closer toward the sun. They pick her out of the solar interference and then lose her again. They know her crew now: the man is Andy Kay, the senior woman is Lady Blue Parks; they appear to do the navigating. Then there is a Connie Morelos and the two twins, Judy Paris and Judy Dakar, who run the communications. The chief Luna voices are women too, Margo and Azella. The men can hear them talking to the Escondita which is now swinging in toward the far side of the sun. Dave insists on monitoring and taping everything that comes through. It proves to be largely replays of their exchanges with Luna and Gloria, mixed with a variety of highly personal messages. As references to cows, chickens, and other livestock multiply Dave reluctantly gives up his idea that they are code. Bud counts a total of five male voices.
"Big deal," he says. "There were more chick drivers on the road when we left. Means space is safe now, the girlies have taken over. Let them sweat their little asses off." He chuckles. "When we get this bird down, the stars ain't gonna study old Buddy no more, no ma'm. A nice beach and about a zillion steaks and ale and all those sweet things. Hey, we'll be living history, we can charge admission."
Dave's face takes on the expression that means an inappropriate topic has been breached. Much to Lorimer's impatience, Dave discourages all speculation as to what may await them on this future Earth. He confines their transmissions strictly to the problem in hand; when Lorimer tries to get him at least to mention the unchanged-language puzzle Dave only says firmly, "Later." Lorimer fumes; inconceivable that he is three centuries in the future, unable to learn a thing.
They do glean a few facts from the women's talk. There have been nine successful Sunbird missions after theirs and one other casualty. And the Gloria and her sister ship are on a long-planned fly-by of the two inner planets.
"We always go along in pairs," Judy says. "But those planets are no good. Still, it was worth seeing."
"For Pete's sake, Dave, ask them how many planets have been visited," Lorimer pleads.
"Later."
But about the fifth meal-break Luna suddenly volunteers.
"Earth is making up a history for you, Sunbird," the Margo voice says. "We know you don't want to waste power asking so we thought we'd send you a few main points right now." She laughs. "It's much harder than we thought, nobody here does history."
Lorimer nods to himself; he has been wondering what he could tell a man from 1690 who would want to know what happened to Cromwell-was Cromwell then?-and who had never heard of electricity, atoms, or the U.S.A.
"Let's see, probably the most important is that there aren't as many people as you had, we're just over two million. There was a world epidemic not long after your time. It didn't kill people but it reduced the population. I mean there weren't any babies in most of the world. Ah, sterility. The country called Australia was affected least." Bud holds up a finger.
"And North Canada wasn't too bad. So the survivors all got together in the south part of the American states where they could grow food and the best communications and factories were. Nobody lives in the rest of the world but we travel there sometimes. Ah, we have five main activities, was `industries' the word? Food, that's farming and fishing. Communications, transport, and space-that's us. And the factories they need. We live a lot simpler than you did, I think. We see your things all over, we're very grateful to you. Oh, you'll be interested to know we use zeppelins just like you did, we have six big ones. And our fifth thing is the children. Babies. Does that help? I'm using a children's book we have here."
The men have frozen during this recital; Lorimer is holding a cooling bag of hash. Bud starts chewing again and chokes.
"Two million people and a space capability?" He coughs. "That's incredible."
Dave gazes reflectively at the speaker. "There's a lot they're not telling us."
"I gotta ask them," Bud says. "Okay?"
Dave nods. "Watch it."
"Thanks for the history, Luna," Bud says. "We really appreciate it. But we can't figure out how you maintain a space program with only a couple of million people. Can you tell us a little more on that?"
In the pause Lorimer tries to grasp the staggering figures. From eight billion to two million… Europe, Asia, Africa, South America, America itself-wiped out. There weren't any more babies. World sterility, from what? The Black Death, the famines of Asia those had been decimations. This is magnitudes worse. No, it is all the same: beyond comprehension. An empty world, littered with junk.
"Sunbird?" says Margo. "Da, I should have thought you'd want to know about space. Well, we have only the four real spaceships and one building. You know the two here. Then there's Indira and Pech, they're on the Mars run now. Maybe the Mars dome was since your day. You had the satellite stations though, didn't you? And the old Luna dome, of course-I remember now, it was during the epidemic. They tried to set up colonies to, ah, breed children, but the epidemic got there too. They struggled terribly hard. We owe a lot to you really, you men I mean. The history has it all, how you worked out a minimal viable program and trained everybody and saved it from the crazies. It was a glorious achievement. Oh, the marker here has one of your names on it. Lorimer. We love to keep it all going and growing, we all love traveling. Man is a rover, that's one of our mottoes."
"Are you hearing, what I'm hearing?" Bud asks, blinking comically.
Dave is still staring at the speaker. "Not one word about their government," he says slowly. "Not a word about economic conditions. We're talking to a bunch of monkeys."
"Should I ask them?"
"Wait a minute… Roger, ask the name of their chief of state and the head of the space program. And -no, that's all."
"President?" Margo echoes Bud's query. "You mean like queens and kings? Wait, here's Myda. She's been talking about you with Earth."
The older woman they hear occasionally says, "Sunbird? Da, we realize you had a very complex activity, your governments. With so few people we don't have that type of formal structure at all. People from the different activities meet periodically and our communications are good, everyone is kept informed. The people in each activity are in charge of doing it while they're there. We rotate, you see. Mostly in five-year hitches; for example, Margo here was on the zeppelins and I've been on several factories and farms and of course the, well, the education, we all do that. I believe that's one big difference from you. And of course we all work. And things are basically far more stable now, I gather. We change slowly. Does that answer you? Of course you can always ask Registry, they keep track of us all. But we can't, ah, take you to our leader, if that's what you mean." She laughs, a genuine, jolly sound. "That's one of our old- jokes. I must say," she goes on seriously, "it's been a joy to us that we can understand you so well. We make a big effort not to let the language drift, it would be tragic to lose touch with the past."
