The commander rubbed his hands. They weren"t as stubborn as he feared.
He"d rescue them.
"Good. I"ll have men aloft in a few minutes."
"Guess it was you who didn"t hear," she said. "Our home is on Earth."

"There"s no one here," said the robot blocking the door.
"We"ll wait." Amantha tried to go inside. The robot wouldn"t move.
It was dark and windy and, from the steps, they could see lights of houses glowing around them. Not many--it was near the edge of the little town. Farther away, over the hill, the ship nestled safely in a valley.
No one had seen them land. They were sure of it.
Ethan removed his hat and his bent shoulders straightened. He seemed to grow taller.
"Rain," he said in awe. "Thirty years and yet I haven"t forgotten what it"s like."
"It"s wet, that"s what it"s like," said Amantha. "Robot, let us in or I"ll have Ethan take a wrench to you. He loves to tinker."
"I can"t be threatened. My sole concern is the welfare of my charge.
Also, I"m too large for any human to hurt me."
"d.a.m.nation, I"m soppin"!" complained Ethan. "It"s better to remember the rain than to be in it."
"Wait till my son Jimmy gets back. He"ll be ravin". Makin" us stay out here and get soaked."
"Son? Is the Jimmy you refer to Pilot James Huntley?"
"Ex-pilot."
"Correct. But he"s not at home. He took his wife to the hospital half an hour ago."
"So soon?" gasped Amantha. "Thought I taught him better than that. Women have got to rest between kids."
"It"s not another child," said the robot with disinterest. "It has to do with one of the ills flesh is heir to and machines are not. Nothing serious."
Ethan fidgeted, turning up his collar. Water began flowing from the eaves. "Stop arguin" and let us in. Jimmy will turn off your juice when he finds you"ve kept his folks outside."
"Folks? He has none here. A mother and father living happily on Mars.
They died quite recently, lost in s.p.a.ce and plunging into the Sun."
"Make up your mind," Amantha said peevishly. "We ain"t on Mars, we weren"t happy and we didn"t get lost and plunge into the Sun."
"I merely repeat--in sequence--the information I"m given or overhear. If it"s inconsistent, so are humans. I"m used to it."
""Mantha, they think we"re dead," said Ethan. He wiped a raindrop away.
"Poor Jimmy!"
A thin wail came from a crack in the door. The robot"s eyes shone briefly, then dimmed.
"What"s that?" asked Amantha. "Sounds like a baby. Thought you said no one was home."
"No responsible adult. Only a child. Because of that, I can admit no one except the parents--or a doctor if I decide one is needed." The robot whirred and drew itself up. "He"s absolutely safe. I"m a Sitta."
"You sure are. Now get out of my way before I jab you. The kid"s crying."
"He is, but it"s no concern of yours. I"m better acquainted with infant behavior than any human can be. The pathetic sob merely means that the child wants attention. I was given no instructions to hold him."
Again the child cried. "Who needs to be told?" demanded Amantha. "n.o.body gives grandmothers instructions."
"He"s got a grandfather to cuddle him," added Ethan. "How far do you think we came to do it?"
"And he"s not cryin" because he wants attention. Something"s stickin"
him and he"s hungry. Don"t you think a grandmother would know?"
"There"s nothing that can stick him, but if, by accident, something sharp had gotten in his bed and if he were also hungry, he would sound like this." The Sitta hunched down and swiveled its head, giving an imitation. "You see? I do nothing but watch babies. It"s built into me."
Inside the house, the child"s tone changed, became querulous, listening.
Interrogatively, it offered a single yowl.
"My a.n.a.lysis was correct. It wanted attention. The parents left so hurriedly, they forgot to give me permission. When I didn"t come to investigate, the child stop--"
The wail burst forth with renewed vigor.
The robot rotated its head and the alert look flashed on and off. It stuttered, "I know w-what I"m doing. But I--I can tell only what has happened to my charge, n-never what _will_!" The Sitta rumbled bewilderedly. "Antic.i.p.ation is beyond my capacity. The child _is_ hurt and hungry. Please come in and help me."
Triumphantly, Amantha followed the robot into the house toward the nursery. She whispered to Ethan, "Sittas ain"t smart. I reckon he never heard a bunch of babies together. If one cries, they all do."
The Sitta barred the path. "You seem sincere and are obviously an expert. But before you go in, understand this--attempt no harm to the being in there. I"m linked."
"You"ll be unlinked if you don"t stop acting balky," warned Amantha. She ducked under his arm and darted toward the crib.
"By linked, I mean that if anything happens that I require aid to handle, an alarm rings in Sittas Circle and help is on the way.
Meanwhile, I can put out fires or carry him unharmed through concrete walls."
"Go ahead, run through a wall," invited Amantha abstractly, s.n.a.t.c.hing up the child. "The darling"s wet, too. Fetch me a diaper."
The robot fetched at her command. And when the child was quiet, even cooing, but with a sharp undertone of protest, Amantha settled back.
"Now we"ve got to feed him."
"They didn"t give me special instructions and I can"t originate. If you hadn"t come, I"d have had to contact a doctor."
