Swigert Jr. in the command ship, they will set the ship's computer to trigger the engine at a specific time. This burn will pull the 2V2-lon LM out of orbit and send it hurtling toward the moon. The Apollo 12 and 13 landing spots are only 95 miles apart, and the astronauts hope to crash the LM between them about 60 miles east of Apollo 12 and 35 miles west of Apollo 13.

to plant a seismometer, each of which will have an active lifetime of at least a year. "WITH 0 NLY one seismometer," said Apollo 13 astronaut Fred W. Haise, Jr. "it is difficult to determine whether an 1 event is a little one close by or a large one far away. With two we'll have the start of a network which will give us this information." Before Haise and James A.

Lovell Jr. leave the moon's Ocean of Storms at a speed of 3,700 miles an hour. No explosion is anticipated because fuel and pressuring gases are to be vented overboard before the impact. The astronauts will not see the crash because they will be on the far side of the moon, but they hope later to photograph results of impact. The aiming point is 140 miles west of the Apollo 12 landing.

All the remaining moon landing crews plan toward an orbit about the sun to get it out of the way. But nine hours after the Apollo 13 launching April 11, ground controllers will change the course by firing small control jets to zero it in on the moon. On this course, it will follow closely the path of the spaceship, but several hundred miles behind. WHEN APOLLO 13 zips behind the moon and into orbit three days after blast off, the 15i2-ton rocket stage is to smash into the By HOWARD BENEDICT CAPE KENNEDY iiPi Two large pieces of Apollo 13 hardware are to crash on the moon to create massive manmade moon-quakes which could tell much about the lunar interior. The 61-foot third stage of the Saturn booster rocket is to smash with a force equal to 11 tons of TNT.

The smaller lunar module LM cabin section, which will be impacted after the astronauts leave ing surfaces to distort the signal.1 That's the type of thing we saw with the Apollo 12 impact. But we don't know why it rang so long. "THE S4B is much larger and will give us a better energy calibration," he said. "We will get readings on the object with a known weight, speed and striking point." On i ous Apollo flights, after the S4B stage separated from the spaceship, it was aimed prise, as the seismometer recorded tremors for 55 minutes. On earth, a similar impact would reverberate only five or six minutes.

"This indicates that the structure beneath the surface of the moon is broken up, with a wide variety of fragments," a space agency geologist said. "The earth is solid and transmits a clear signal. If it weren't solid and the material heneath the surface were badly broken up, you would have many reflect the moon, is to hit with a force of 1.2 tons. THE IMPACT of the rocket stage, called an S4B, will be recorded by a seismometer left on the moon last November by the Apollo 12 astronauts. The Apollo 13 crew will plant a second seismometer, and they hope to crash their LM between the two instruments.

When the Apollo 12 lunar module was crashed after it no longer was needed, scientists on the ground received a big sur 2 Spacemen Wed School Sweethearts Up Haise And Family Lovell And Family daughter Barbara, wife, Marilyn, son, Jeffrey, Lovell, and daughter Susan.

and civilian Fred W. Haise the next two astronauts to land on the moon, both married their high school sweethearts. Lovell, 42, married Marilyn Gerlach, a fun-loving brunette from Milwaukee with whom he used to ride the streetcar to school every day. HAISE, 36, married Mary Griffin "Sissy" Grant, the daughter of a Biloxi, pharmacist and a graduate of Stephens College, a girls school in Colombia, Mo. Marilyn Lovell is cute, active and efficient.

She comes by the first two traits naturally. The efficiency might be a product of her environment, because her husband has been more active than any other astronaut. Lovell was a backup pilot on Gemini 4, the pilot on Gemini 7, a backup on Gemini 9, command pilot on Gemini 12, pilot on Apollo 8, backup on Apollo 11 and now commander of Apollo 13. "HE'S NEVER really stopped training since he was a backup pilot for Gemini 4 in June, 1965," she said. This has placed much of the burden on her to run the home and discipline the four Lovell children Barbara, 16; James A.

Ill, 15; Susan, 11; and Jeffrey, 4. "She runs the house," a friend said. "When she says 'no' she means it, and they know it. But she doesn't say 'no' that much. "SHE SELDOM loses her temper.

She has a wonderful sense of humor. Marilyn is probably the ibest-liked of all the astronaut wives. There's nobody she can't get along with," the friend said. The Lovells live in Timber Cove, Texas, a subdivision where most of the original seven astronauts lived, too. Their house in on Glenn's Bayou, so-called because it dead-ended at John Glenn's back yard.

Lovell and his oldest daughter, Barbie, have a small sailboat at the family's backyard dock. SHE ALSO takes flying lessons at nearby Ellington Air Force Base, but her dad won't let her solo until after she has flown with him. James III, or Jay, is in his first year at St. John's Military Academy at Delafield, Wis. He will remain at the academy during the flight.

Jeffrey was to be born during Lovell's Gemini 7 flight, but arrived late "because the stork didn't realize he was part of the flight plan," according to Marilyn. "HE SHOWS more enthusiasm for the space program than the others," a neighbor said. "Every time he sees a rocket or a picture of daddy, he gets excited." THE SOUTH LARGEST HOME FURNISHERS Since1885 (HAVERTYS) Just as Marilyn Lovell was carrying Jeff during Lovell's first flight, Mary Haise is pregnant during this flight, her husband's first flight. Mrs. Haise is expecting in July, but she hasn't let the added strain of being pregnant along with all the preflight activities bother her.

This also will be the fourth Haise child to go with Mary Margaret, 14; Frederick, 11; and Stephen, 8. THE HAISES are a close-knit family that prefer to do things together than make the party circuit. "I've never seen them at one of the pilots' parties," a former NASA official said. "They go to parties at Christmas or to a movie occasionally with the children, but you'd never see them pick up and go out to a night club," a friend said. MRS.

HAISE looks chic because she has had her hair cropped close in a cap-cut. It looks extremely fashionable, but she had it cut for practical rather than esthetic reasons. It's easier to wash. The key to Mrs. Haise is practicality.

She does not wear frilly clothes, and seldom wears jewelry not even a watch. "She buys expensive things and then inexpensive things and interchanges them so she gets the most of her money," a friend said. The Haises live in a two-story brick and cedar shake home six doors down the street from the Neil Armstrongs in El Largo. iP'lSif LiiWM cintuiy ot Quality Mmuliclunng.
