But ten minutes later I was handling myself fairly well and in half an hour I felt as if I had worn one all my life. The distributed weight wasn't too great (and I knew it wouldn't amount to much on the Moon). The joints were just a case of getting used to more effort. I had had more trouble learning to swim.
It was a blistering day: I went outside and looked at the Sun. The polarizer cut the glare and I was able to look at it. I looked away; polarizing eased off and I could see around me.
I stayed cool. The air, cooled by semi-adiabatic expansion (it said in the manual), cooled my head and flowed on through the suit, washing away body heat and used air through the exhaust valves. The manual said that heating elements rarely cut in, since the usual problem was to get rid of heat; I decided to get dry ice and force a test of thermostat and heater.
I tried everything I could think of. A creek runs back of our place and beyond is a pasture. I sloshed through the stream, lost my footing and fell -the worst trouble was that I could never see where I was putting my feet. Once I was down I lay there a while, half floating but mostly covered. I didn't get wet, I didn't get hot, I didn't get cold, and my breathing was as easy as ever even though water shimmered over my helmet.
I scrambled heavily up the bank and fell again, striking my helmet against a rock. No damage, Oscar was built to take it. I pulled my knees under me, got up, and crossed the pasture, stumbling on rough ground but not falling. There was a haystack there and I dug into it until I was buried.
Cool fresh air ... no trouble, no sweat.
After three hours I took it off. The suit had relief arrangements like any pilot's outfit but I hadn't rigged it yet, so I had come out before my air was gone. When I hung it in the rack I had built, I patted the shoulder yoke. "Oscar, you're all right," I told it. "You and I are partners. We're going places." I would have sneered at five thousand dollars for Oscar.
While Oscar was taking his pressure tests I worked on his electrical and electronic gear. I didn't bother with a radar target or beacon; the first is childishly simple, the second is fiendishly expensive. But I did want radio for the space-operations band of the spectrum-the antennas suited only those wavelengths. I could have built an ordinary walkie-talkie and hung it outside-but I would have been kidding myself with a wrong frequency and gear that might not stand vacuum. Changes in pressure and temperature and humidity do funny things to electronic circuits; that is why the radio was housed inside the helmet.
The manual gave circuit diagrams, so I got busy. The audio and modulating circuits were no problem, just battery-operated transistor circuitry which I could make plenty small enough. But the microwave part- It was a two-headed calf, each with transmitter and receiver-one centimeter wavelength for the horn and three octaves lower at eight centimeters for the spike in a harmonic relationship, one crystal controlling both. This gave more signal on broadcast and better aiming when squirting out the horn and also meant that only part of the rig had to be switched in changing antennas. The output of a variable-frequency oscillator was added to the crystal frequency in tuning the receiver. The circuitry was simple-on paper.
But microwave circuitry is never easy; it takes precision machining and a slip of a tool can foul up the impedance and ruin a mathematically calculated resonance.
Well, I tried. Synthetic precision crystals are cheap from surplus houses and some transistors and other components I could vandalize from my own gear. And I made it work, after the fussiest pray-and-try-again I have ever done. But the consarned thing simply would not fit into the helmet.
Call it a moral victory-I've never done better work.
I finally bought one, precision made and embedded in plastic, from the same firm that sold me the crystal. Like the suit it was made for, it was obsolete and I paid a price so low that I merely screamed. By then I would have mortgaged my soul-I wanted that suit to work.
The only thing that complicated the rest of the electrical gear was that everything had to be either "fail-safe" or "no-fail"; a man in a space suit can't pull into the next garage if something goes wrong-the stuff has to keep on working or he becomes a vital statistic. That was why the helmet had twin headlights; the second cut in if the first failed-even the peanut lights for the dials over my head were twins. I didn't take short cuts; every duplicate circuit I kept duplicate and tested to make sure that automatic changeover always worked.
Mr. Charton insisted on filling the manual's list on those items a drugstore stocks-maltose and dextrose and amino tablets, vitamins, dexedrine, dramamine, aspirin, antibiotics, antihistamines, codeine, almost any pill a man can take to help him past a hump that might kill him. He got Doc Kennedy to write prescriptions so that I could stock Oscar without breaking laws.
When I got through Oscar was in as good shape as he had ever been in Satellite Two. It had been more fun than the time I helped Jake Bixby turn his heap into a hotrod.
But summer was ending and it was time I pulled out of my daydream. I still did not know where I was going to school, or how-or if. I had saved money but it wasn't nearly enough. I had spent a little on postage and soap wrappers but I got that back and more by one fifteen-minute appearance on television and I hadn't spent a dime on girls since March- too busy. Oscar cost surprisingly little; repairing Oscar had been mostly sweat and screwdriver. Seven dollars out of every ten I had earned was sitting in the money basket.
But it wasn't enough.
I realized glumly that I was going to have to sell Oscar to get through the first semester. But how would I get through the rest of the year? Joe Valiant the all-American boy always shows up on the campus with fifty cents and a heart of gold, then in the last Chapter is tapped for Skull-and-Bones and has money in the bank. But I wasn't Joe Valiant, not by eight decimal places. Did it make sense to start if I was going to have to drop out about Christmas? Wouldn't it be smarter to stay out a year and get acquainted with a pick and shovel?
Did I have a choice? The only school I was sure of was State U. -and there was a row about professors being fired and talk that State U. might lose its accredited standing. Wouldn't it be comical to spend years slaving for a degree and then have it be worthless because your school wasn't recognized?
State U. wasn't better than a "B" school in engineering even before this fracas.
Rensselaer and CalTech turned me down the same day-one with a printed form, the other with a polite letter saying it was impossible to accept all qualified applicants.
Little things were getting my goat, too. The only virtue of that television show was the fifty bucks. A person looks foolish wearing a space suit in a television studio and our announcer milked it for laughs, rapping the helmet and asking me if I was still in there. Very funny. He asked me what I wanted with a space suit and when I tried to answer he switched off the mike in my suit and patched in a tape with nonsense about space pirates and flying saucers. Half the people in town thought it was my voice.
It wouldn't have been hard to live down if Ace Quiggle hadn't turned up. He had been missing all summer, in jail maybe, but the day after the show he took a seat at the fountain, stared at me and said in a loud whisper, "Say, ain't you the famous space pirate and television star?"
I said, "What'll you have, Ace?"
"Gosh! Could I have your autograph? I ain't never seen a real live space pirate before!"
"Give me your order, Ace. Or let someone else use that stool."
"A choc malt. Commodore-and leave out the soap."
Ace's "wit" went on every time he showed up. It was a dreadfully hot summer and easy to get tempery. The Friday before Labor Day weekend the store's cooling system went sour, we couldn't get a repairman and I spent three bad hours fixing it, ruining my second-best pants and getting myself reeking. I was back at the fountain and wishing I could go home for a bath when Ace swaggered in, greeting me loudly with "Why, if it isn't Commander Comet, the Scourge of the Spaceways! Where's your blaster gun, Commander? Ain't you afraid the Galactic Emperor will make you stay in after school for running around bare-nekkid? Yuk yuk yukkity yuk!"
