bounce between Washington and the station only 22,300 miles up was only a quarter

second. “We’ve patched Earthside stations to blanket the Moon with our call. Another

broadcast blankets the far side from Station Newton at the threebody stable

position. Ships from Tycho are orbiting the Moon’s rim-that band around the edge

which is in radio shadow from us and from the Newton. If we

ear- “Yes, yes! How about radar search?”

“Sir, a rocket on the surface looks to radar like a million other features

the same size. Our one chance is to get them to answer.. . if they can.

Ultrahigh-resolution radar might spot them in months-but suits worn in those little

rockets carry only six hours’ air. We are praying they will hear and answer.”

“When they answer, you’ll slap a radio direction finder on them. Eh?”

“No, sir.”

“In God’s name, why not?”

“Sir, a direction finder is useless for this job. It would tell us only that

the signal came from the Moon-which doesn’t help.”

“Doctor, you’re saying that you might hear Betsy- and not know where she

is?”

“We’re as blind as she is. We hope that she will be able to lead us to her.

. . if she hears us.”

“How?”

“With a laser. An intense, very tight beam of light. She’ll hear it-”

“Hear a beam of light?”

“Yes, sir. We are jury-rigging to scan like radar- that won’t show anything.

But we are modulating it to give a carrier wave in radio frequency, then modulating

that into audio frequency-and controlling that by a piano. If she hears us, we’ll

tell her to listen while we scan the Moon and run the scale on the piano-”

“All this while a little girl is dying?”

“Mister President-shut up!”

“Who was THAT?”

“I’m Betsy’s father. They’ve patched me from Omaha. Please, Mr. President,

keep quiet and let them work. I want my daughter back.”

The President answered tightly, “Yes, Mr. Barnes. Go ahead, Director. Order

anything you need.”

In Station Meridian the Director wiped his face. “Getting anything?”

“No. Boss, can’t something be done about that Rio Station? It’s sitting

right on the frequency!”

“We’ll drop a brick on them. Or a bomb. Joe, tell the President.”

“I heard, Director. They’ll be silenced!”

“Sh! Quiet! Betsy-do you hear me?” The operator looked intent, made an

adjustment.

From a speaker came a girl’s light, sweet voice:

“-to hear somebody! Gee, I’m glad! Better come quick-the Major is hurt.”

The Director jumped to the microphone. “Yes, Betsy, we’ll hurry. You’ve got

to help us. Do you know where you are?”

“Somewhere on the Moon, I guess. We bumped hard and I was going to kid him

about it when the ship fell over. I got unstrapped and found Major Peters and he

isn’t moving. Not dead-I don’t think so; his suit puffs out like mine and I hear

something when I push my helmet against him. I just now managed to get the door

open.” She added, “This can’t be Farside; it’s supposed to be night there. I’m in

sunshine, I’m sure. This suit is pretty hot.”

“Betsy, you must stay outside. You’ve got to be where you can see us.”

She chuckled. “That’s a good one. I see with my ears.”

“Yes. You’ll see us, with your ears. Listen, Betsy. We’re going to scan the

Moon with a beam of light. You’ll hear it as a piano note. We’ve got the Moon split

into the eighty-eight piano notes. When you hear one, yell, ‘Now!’ Then tell us what

note you heard. Can you do that?”

“Of course,” she said confidently, “if the piano is in tune.”

“It is. All right, we’re starting-”

“Now!”

“What note, Betsy?”

“E flat the first octave above middle C.”

“This note, Betsy?”

“That’s what I said.”

The Director called out, “Where’s that on the grid? In Mare Nubium? Tell the

General!” He said to the microphone, “We’re finding you, Betsy honey! Now we scan

just that part you’re on. We change setup. Want to talk to your Daddy meanwhile?”

“Gosh! Could I?”

“Yes indeed!”

Twenty minutes later the Director cut in and heard:

“-of course not, Daddy. Oh, a teensy bit scared when the ship fell. But people take
