(P) The power failure on Apollo 13 probably was caused when the fuel cell was struck by a very small meteorite, Dr. Harvey Nininger said today. Nininger, regarded as an expert on the subject, said he had given this "very positive opinion" to the National Aeronautics and Space Administration after being consulted by it Monday night. HE SAID he didn't see why some technologists think the mishap may have been caused by a connection going wrong on the spacecraft since there have been SO many successful launches and returns.

"We've known all along of the hazard of meteorites in space," he said, "but we've said very little about it because the flights have been so successful. "I feel that while we probably have had an encounter with a meteorite, it could have been very disastrous if it had been larger or had part where the men are living." NININGER'S collection of meteorites was purchased by the National Science Foundation in 1967 and placed at the Center for Meteorite Studies at Arizona State University. Nixon Picks Admiral To Head Joint Chiefs WASHINGTON (P) President Nixon announced today he will nominate Adm. Thomas H. Moorer, chief of naval operations, to succeed retiring Gen.

Earle G. Wheeler as chairman of the Joint Chiefs of Staff. Moorer, 58, will take over from Wheeler on July 2. NIXON'S CHOICE to be the new chief of naval operations is Vice Adm. Elmo R.

Zumwalt who is commander of naval forces in Vietnam. Wheeler, 62, has been chairman of the joint chiefs since July 6, 1964. His term was extended twice, each time for one year, by two presidents--Nixon last year and Lyndon B. Johnson in 1968. Moorer, who has been chief of naval operations since June 1967, will be the second Navy man to serve May Draft Call Put At 15,000 WASHINGTON (P The Selective Service System will draft 15,000 men for the Army in May, the Pentagon announced today.

The May draft is a drop of 4,000 men from each of the three previous months' manpower requests. Back? 'Barely' Speedy Trip Back Weighed SPACE CENTER, Houston (P) Apollo 13's imperiled astronauts battled to bring their crippled spaceship back to earth today as Mission Control Center considered a risky "superfast" return that would propel them home a day early and perhaps save their lives. "Yes, barely," flight controller Glynn Lunney said when asked whether the three spacemen would make it back from their aborted moon landing mission, suddenly cut short Monday night when a violent rupture of unknown origin ripped through pressurized fuel tanks. Officials are considering the quick return to bring Apollo 13 back to earth Thursday because they are concerned about oxygen and water supplies aboard the lunar module from which the astronauts are drawing life support. JAMES A.

Lovell Fred W. Haise Jr. and John L. Swigert Jr. conserved Related Stories Pages 2A, 4A, 5A these vital consumables as they raced farther from earth, toward a loop around the moon tonight before starting the quartermillion-mile homeward journey.

Looping the moon is the safest way home, officials said, because Apollo 13 was close to its target when the accident happened and already was on a course that would take it around the moon's backside. To stop short of the moon would have required considerable power and fuel expenditure, something the astronauts don't have with their big command ship engine idled by electrical failure. THE ONLY powerplant available is the lunar module descent engine, the one intended to lower Lovell and Haise to the moon's surface. The spacemen triggered the engine 30 seconds early today to adjust their course slightly to a path that would take them around the moon and bring them back to earth late Friday if they made no other maneuver. If that engine had failed to ignite, Apollo 13 would have swung back toward earth but would have missed by some 20,000 miles and would have been lost forever in space.

To speed the homeward trip by 10 hours, Lovell, Haise and late substitute Swigert plan at 9:40 p.m. EST tonight to trigger the engine again to increase their 2.600 m.p.h. speed by 558 miles an hour. That would land them in the Pacific Ocean north of New Zealand at 1 p.m. EST Friday.

MISSION Control said at midmorning it still favored this plan. But officials huddled for a long time to consider a "superfast" return which would mean a longer burn of the lunar Garnet Gold Game (Florida State's spring football classic.) 8 P.M.

CONEA module engine. The result would be an earth landing about 1 p.m.

Thursday. Officials listed two drawbacks: -The service compartment at the base of the command ship would have to be jettisoned and this could create a heat protection problem. -The maneuver requires almost perfect alignment of the inertial guidance platform, something that may not be possible with the lunar module system. Normally, the command ship system would be used for such a firing. "WE WILL continue to study this option several hours," the control center said.

Officials are concerned mainly with the water supply. With 75 hours to go, based on a Friday landing, the spaceship had enough water for 88 hours, a margin of 13 hours. To have this margin, the astronauts will have to power down to minimum electrical power for most of the journey, reducing the average hourly water consumption from five to 2.68 pounds. The water is used for cooling the electronics and cabin oxygen as well as for drinking. At the same time, the oxygen supply was good for another 125 hours, a margin of 50 hours, barring unforeseen events.

NEITHER the United States nor Russia has a space rescue capability. So the astronauts will have to depend on their skill and that of hundreds of experts on the ground to get home. Following the tank rupture, the astronauts activated the systems of the attached lunar module, or LM. They opened the connecting tunnel between the two craft so oxygen would flow into the command ship and make it livable. The cramped LM is difficult to sleep in, so the astronauts will rest in the command ship.

Swigert retired early today while Haise and Lovell monitored the command and lunar ships, respectiveplanning to sleep later. ly, The astronauts remained calm and poised as they wrestled with the many procedures needed to stabilize their craft and to stretch their consumables. To improve oxygen circulation and prevent a buildup of carbon dioxide in the command ship, Mission Control Center told the to use a hose astronauts from one of the unused space suits and extend it from the LM oxygen supply through the tunnel. Lovell. Haise and Swigert were told to place bags water in any excess and to turn off all nonessential items requiring power.

More than 2,600 students in Bradenton and Palmetto schools today were cross- bused across the Manatee Kirk In New Orleans Page 7A River which runs between the cities. THE ONLY reported incident came in Palmetto when a Negro parent temporarily stopped a school bus, saying he did not want his children being cross-bused. While exact figures are not in, Dr. Jack Davidson said that attendance "is pretty in fact it's better than we had anticipated." Davidson said he did not know how many parents may have kept their children home but indicated it was a "very small number." At Memorial Elementary School, several busloads of white students were brought into the Negro sector of Palmetto from Bradenton schools and were met by hordes of newsmen.

"Actually, though," said Dr. Davidson, "things have gone very, very well." AT JESSE Miller Elementary School in Bradenton several busloads of Negro children in grades one through four came in, disembarked and went to their classes without incident. Police were standing by in case they were needed. A few white parents approached reporters to tell them they thought Gov. Claude R.

Pope Prays VATICAN CITY (UPI) Vatican sources said today Pope Paul VI is praying for the safety of the three man crew of Apollo 13. Prayer Asked WASHINGTON (P) The Senate passed a resolution today calling on all Americans to pause at 9 o'clock tonight to pray for the safe return of the Apollo 13 astronauts. The resolution was introduced by Sen. George Murphy, and was approved swiftly by voice vote.

SPACE CENTER, Houston (P) Never once, in the greatest crisis of their lives, in a danger that had materialized only in fiction, did the Apollo 13 astronauts lose their cool. "Hey, we've got a problem here!" EVEN THAT first cry of alarm, across 202,000 miles of space, was restrained, though urgent. They'd finished a television show--such standard fare for a jaded public that none of the television networks made time for it. Mission control saw it and congratulated them on it. Now the ground was giving instructions for positioning the spacecraft to look for the comet Bennett.

"Hey, we've got a problem here." It was James A. Lovell the spacecraft commander, the only human to make four trips into space. "THIS IS Houston, say again please." "Houston, we've had a problem. We've had a main bus interval." A power failure! An imbalance in the intricate system that gives oxygen and direction and the fragile voice lifeline to ground. BY THE very laws of the universe they challenged and used, their spacecraft continued on to the moon as indeed it would even if their ship were a derelict.

Many hours before they had forsaken the relative safety of a "free return" that would have required only the pull of the moon and the earth to put them back on earth. Deliberately they had changed the course so Lovell and Fred W. Haise could land on the moon. "We're looking at it." A hundred experts on the ground, others quickly summoned. But advice was all that was possible to help three men in a disabled ship.

"OKAY, RIGHT now, Houston, the voltage is pretty large bang associated with the caution and warning there." Fred." Fred Haise, a first-timer in looking good. And we had a space. Beside him John L. Swigert also a rookie, but more so, an emergency substitute on the flight. "It's a gas of some sort." They could see it out of their window.

Droplets that turned into snow and drifted off like feathers from a molting bird. THE GAS, it turned out, was their oxygen; a commodity on which their very lives depend. Back and forth, across the miles, spun the questions, the numbers, the readings. Crisp and cool. Urgent, but not panicked.

"Okay, 13, we've got lots and lots of people working on this, we'll get you some dope as soon as we have it and you'll be the first to know." Nobody said it but they knew and the ground knew that now there was no possibility of landing on the moon. Now the only thing was to use the power that remained--the power that would have set them on the lunar surface--to get back to earth. "I didn't think I'd be back this soon," said Fred Haise, who would have been the sixth human to touch the moon. as chairman of the joint chiefs. Adm.

It will be close, but they'll get home if nothing else bad happens. Like kissing cousins the command ship Odyssey and the lunar lander Aquarius continued on to the moon. Now for Aquarius there was not the noble voyage to the highlands of the moon, nor the splendor of being crashed empty against its surface in the name of science. Now they were plundering her holds for the oxygen they'd need to sustain them on a four-day journey back to earth, more than ever full of risks.
