Perkinson Seienct Sditor, Thi ftininj Sun Apollo Mission Control Cen ter, Houston, Texas A condensed version of the day-by-day highlights of Apollo 11 man's first attempt to land on the moon is outlined below: A somewhat similar schedule Is due to be used on Apollo 12, 13 and 14, three other manned flights to the moon scheduled during the next 12 months. All times are in Eastern Daylight Time, and the schedule is based on a 9.32 A.M.

liftoff from Cape Kennedy on July 16, Event numbers refer to the 85 events or "milestones" listed on the official NASA lunar landing profile above. July 16 Wednesday Liftoff Day Events 1 through 28 occur on the first calendar day of the flight. 9.32 A.M. Liftoff for the three astronauts atop the 363 foot high Apollo 11-Saturn rocket. At liftoff the entire rocket as sembly will weigh more than 2,000 tons.

9.43 A.M. Apollo 11 due to begin orbiting the earth about 100 miles up at a speed of 17,000 miles an hour. 12.18 P.M. TLIor trans-lunar-injectionoccurs as the S-1V-B stage of the rocket fires. That burn is due to kick the Apollo 11 up to a speed of about 25,000 miles an hour.

If the burn succeeds, the Apollo 11 will break out of EPO-or earth parking orbit with speed enough to carry it nonstop around the moon and back to earth. J2.43 P.M.-1.43 P.M.-Com-mand module separates from the S-IV-B stage, then makes a U-turn in space, docks with and withdraws the LEM from the S-IV-B 9.16 P.M. First mid-course Men On The period. BY MIDNIGHT Saturday, July 19 the Apollo 11 crew is due to be making Its sixth orbit or loop-the-loop around the moon. July 20 Sunday Lunar Landing Day Events 44 through 50 on the accompanying diagram.

6.32 A.M. Astronauts end eight-hour sleep-rest period. 7.57 A.M. Aldrin enters the LEM, followed 25 minutes later by Armstrong. LEM Undocks 1.50 P.M.

LEM undocks or detaches itself from the command module and the two craft fly formation across the front side of the moon. 1.S2 P.M.-J.22 P.M. Color telecast of lem flying formation with command capsule around moon. 3.14 P.M.-LEM fires descent engine and heads downward for landing site on the moon. 4.23 P.M.

Touchdown for the first manned landing on the moon. MIDNIGHT, July 20 Aldrin and Armstrong after eight hours rest and two hours for eating prepare to become the first humans to walk on the surface of the moon. July 21 Monday Walk On The Moon Day Events 50 through 68 on the accompanying diagram. 1.57 A.M.-2.07 A.M. Color telecast from command module of Apollo II lunar landing site, from 60 miles up.

2.02 A.M. Armstrong crawls on to the front porch of the LEM "feet first-belly down," and prepares to slide backwards down ladder to the lunar surface. 2.12 to 4.52 A.M. Live black IMS "i'' i rest-sleep period. 9.39 A.M.

Seventh and final midcourse correction of mission if needed. 12.45 P.M.-Apollo 11 begins to re-enter earth's atmosphere at an altitude of 400,000 feet. During re-entry the spacecraft will reach a peak speed of 25,000 miles an hour and the temperatures on its heat shield will be about 5,000 degrees Fahrenheit. 12.49 P.M.T-Splashdown In the Pacific Ocean some 1,000 miles south of Hawaii. July 24-August 10 Quarantine Phase In the past all manned spaceflights have been considered over at splashdown and recovery.

Apollo 11 is different. As George H. Hage, mission director, explains It: "Apollo 11 is the first mission that doesn't really end with recovery." The post-flight phase of the Apollo 11 timeline as far as the astronauts are concerned Is: "Splashdown plus 70 minutes The astronauts emerge the command capsule, are lifted by helicopter and head for the Navy aircraft carrier The U.S.S. Hornet. "Splashdown plus 55 hours-Astronauts in mobile quarantine facility at Ford Island, Hawaii.

"Splashdown plus 57 hours-Astronauts transferred in sealed van to C-141, heavy lift aircraft. JULY 27-Splashdown plus 67 hours crew still In isolation arrive at, enter the Lunar Receiving Laboratory at Houston. AUGUST 10 Apollo 11 astronauts due to end nominal 21-day quarantine. 3 2.17 A.M. Armstrong grabs first moon rocks and takes man's first step on the moon.

2.29 A.M. Aldrin joins Armstrong on lunar surface and two deploy five scientific packages. 4 A.M. Aldrin re-enters the ascent stage of the LEM. 4.57 A.M.

Armstrong rejoins Aldrin in LEM and moon walk ends. 1.58 P.M.-Liftoff from moon. 1.32 P.M.-LEM docks with command module, 60 nautical miles above moon. 1.25 P.M.-LEM is jettisoned or dumped In orbit around the moon. BY MIDNIGHT, Monday, July 21, the Apollo 11 is due to be on its thirtieth and last orbit of the moon before the astronauts head back to earth.

There is a possibility that the Apollo 11 astronauts may make an additional six orbits of the moon before heading back to earth. That option will depend upon how tired the astronauts are after their gruelling experience and on whether the astronauts would like an additional eight to ten hours of rest before making the crucial rocket burn designed to bring them back home. The decision on whether to add the six additional orbits will be made by the astronauts themselves. If they decide to ex ercise their option of resting for six more orbits of the moon all the times that follow would have to be "updated." Splashdown time however, would only change by a few minutes, NASA says. July 22 Monday Going Home Day 12.56 A.M.

Trans-Earth Injection or TEI is the time The Apollo 1 I It i moon capture orbit. As the Apol lo 11 streaks homeward its speed in relation to the earth itself is some 5,000 miles an hour. 11 A.M. Apollo 11 begins to leave "moon's sphere of influence" and enters "earth's sphere of influence." Then the spacecraft is due to be about some 35,000 miles from the moon and some 200,000 miles from earth. At the point of "equigrav-isphere" the space craft reaches the lowest speed of its return journey to earth.

That low speed would be about 3,300 miles an hour. Midcourse correction number 5, if required. 9.02 P.M.-9.17 P.M. Color telecast from Apollo 11 on way back to Earth. 11.28 P.M.

Crew begins rotatr ine seven-hour rest period. By midnight Tuesday, July 22, the Apollo 11 should be about 70,000 miles from the moon and about 165,000 miles from earth, The craft's speed should be about 3,600 miles an hour. July 23 Wednesday Events 69 to 72 on the accom parrying diagram. 6.35 P.M. Midcourse correc tion 6, if required.

7.02-7.17 P.M.-Color telecast from Apollo on way back to earth. By midnight July 23 the Apollo 11 should be about 60,000 miles from earth and about 160,000 miles from the moon. The spacecraft speed then would he about 5,000 miles an hour and increasing rapidly. July 24 Thursday Splashdown Day 6.38 A.M. All three astro- mmsffM i (v 11 Astronauts i if I correction, if needed, during TLC, trans-lunar coast.

Trans-lunar coast is the 73 hours and 11 minutes that are due to elapse between the time the astronauts actually start on the trajectory that will take them behind the moon and the time they begin their first orbit of the moon. 11.02 P.M.-Apollo 11 astronauts begin their first nine-hour sleep and rest period. BV MIDNIGHT, July 18, Apollo 11 is due to be some 75,000 miles from earth and 170,000 miles from the moon. The spacecraft's speed is due to have dropped from a peak of about 25,000 jmles an hour to around 4,800 to 4,900 miles an hour. July 17 -Thursday Events 29 through 33 on ac companying diagram.

J.02 A.M. Astronauts end first nine-hour sleep and rest period. 12.18 P.M.-Second mid-course correction during trans- lunar coast, if required. 7.32-7.47 P.M. First live color telecast from Apollo 11 on its way to the moon.

10.32 P.M.-Apollo 11 astro. nauts begin 10-hour sleep-rest period. BY MIDNIGHT July 17 Apollo 11 and its three astronauts are due to be some 138,527 miles from earth and some 82,000 miles from the moon. The craft's speed is due to have dropped to about 2,900 miles an hour. July IS Friday Events 34 through 37 on accompanying diagram.

8.32 A.M. Apollo 11 astronauts end second sleep-rest period. S.17 P.M. Third mid-course correction, if required. Moon-I shows, NASA breaks down man's first journey to and from the moon into 85 steps.

Should the Apollo 11 be unable to negotiate any of those steps as they occur, the mission could end in disaster. The Astronauts The Apollo 11 astronauts, of course, are: NEIL A. ARMSTRONG, the 38-year-old civilian commander of Apollo 11. He is due to be the first man in history to walk on the moon Armstrong is the father of two boys, Eric, 12, and Mark, 9. Armstrong is a graduate of Purdue University and the Uni versity of Southern California.

He is making his second space flight. His first flight, "the wild ride of Gemini 8," almost ended in disaster before the spacecraft was brought down to an emer gency landing in the Pacific. COL. EDWIN E. ALDRIN, JR.

The 39-year-old astronaut who will accompany Armstrong during the perilous flight from the command module down to the surface of th moon. Colonel Aldrin, who is due' to be the second man to walk on S.40 P.M.-Colonel Aldrin en-1 ters LEM for first time in light. Armstrong joins him later. 7.07 P.M.-Aldrin leaves LEM and returns 'to command cap sule, still docked with LEM. 7.14 P.M.

Armstrong leaves LEM and rejoins Aldrin and Col lins in command capsule. 7.32 P.M,-7.47 P.M.-Second live color telecast from Apollo 11 command capsule. 9.32 P.M. Astronauts begin third and last sleep period before going behind the moon for the first time. This sleep-rest period is due to last nine hours.

11.30 P.M.-Apollo 11 and crew Degin to enter what is called "the lunar sphere of influence." Apollo 11 should then be about 190,535 nautical miles from earth and some 33,000 nautical miles from the moon. At the point of "equi-gravis- phere," where in theory the pull or the moon and the pull of the earth on Apollo 11 are equal, the spacecraft speed should have dropped to about 2,127 statute miles an hour. "By midnight July 18, Apollo 11 should be well within the moon's sphere of influence, being some 31,000 miles from the moon and some 187,000 miles from earth. Apollo's speed should be about 2,550 statute miles an hour in relation to the moon and that speed should continue to increase. July 19 Saturday Lunar Orbit Day Events 37 through 44 on accompanying diagram.

8.32 A.M. Astronauts end sleep-rest period. 8.27 A.M. Fourth mid-course correction if needed. 1.20 P.M.-Apollo 11 flashes behind the moon for the first time.

The craft should be some 290 statute miles in front of the moon and traveling at a speed the moon, is a graduate of West Point and has a doctorate in astronautics from the Massa chusetts Institute of Technology. He is the father of two boys and a girl. The children are J. Michael, 13; Janice 12, and Andrew 11. Colonel Aldrin will be making his second space flight.

His first was aboard Gemini 12 when he twice flew around the earth, walking in space, and standing up in the hatch performing sci entific experiments outside the spacecraft. LT. COL. MICHAEL COL- LINS. 38, is the command mod ule pilot.

That means he will re main aboard that craft, circling 60 miles above the moon, while Armstrong and Aldrin descend to, land on and take off from the moon. Second Space Flight Colonel Collins graduated from West Point in 1952. He is the father of two girls and a boy. His children are Kathleen, 10; Ann 9, and Michael 6. Collins, like his colleagues, is also making his second space flight.

His first orbital flight was aboard Gemini 10. Collins, incidentally, is due to be the chief camera man for the live color telecasts that are due to be made from the command of about 5,300 statute miles an hour. 1.28 P.M.-While behind the moon and completely out of communication with earth, Apollo 11 fires Its engine to cut its speed by some 2,000 statute miles an hour. At that time the Apollo 11 should be 110 to 115 statute miles above the moon and some 215,000 nautical miles from earth. Abrupt Cut In Speed The burn, called the LOI-One Burn, is designed to abruptly chop Apollo 11 'a speed from 300 statute miles an hour to slightly less than 3,300 miles an hour.

The drop in speed enables the spacecraft to be captured by the moon in an orbit that swings the craft from 69 to 200 statute miles above the moon. 1.52 P.M.-K the LOI One burn was successful, the Apollo 11 due to its decreased speed should flash from behind the moon for the first time. 4.02-4.17 P.M.-Color telecast from lunar orbit. 5.41 P.M. After two elliptical orbits of the moon, Apollo 11 is due to fire its service propulsion system engine again in what is called the LOI-Two burn.

Cuts Speed More That burn is due to cut an additional 95 miles an hour from Apollo ll's speed. If the burn is successful, Apollo 11 should be in a circular orbit 69 statute miles above the moon and traveling at a speed around the moon of about 3,200 statute miles an hour. 7.14 P.M.-Colonel Aldrin reenters the LEM for a second inspection of the craft that is due to land the first two Ameri cans on the moon. 9.21 P.M. Aldrin rejoins Armstrong and Collins in the command module.

10.32 P.M.-Apollo 11 astro module en route to and from the moon. Aldrin and Armstrong will take turns using the black and white television camera that is designed to return live telecasts from the surface of the moon. Mounting Of Moon Camera The moon camera Is so mounted that hopefully it will automatically zoom in on Armstrong as he climbs down from the LEM'S "front porch" and takes man's first short walk on the moon. The color TV camera in the command module and the black and white lunar surface camera were both designed, developed and built by the men and women at the Westinghouse Defense and Space Center, at Baltimore's Friendship International Airport. The color camera is estimated to have cost $500,000 and the black and white camera 000.

Currently each can now be built for between $40,000 and $50,000 both NASA and Westing. house spokesmen say. TOMORROW The hazards and taskf that Armstrong and Aldrin will face during man's first attempt to walk on the surface of the moon. A Preview Of Apollo 1 1 tContinued from Page A 11 rently designated as Apollo 12, 13, and 14. If Apollo 11 is successful in completing its mission, Apollo 12 Is to be launched in November, Apollo 13 in March and Apollo 14 In June or July of next year.

Should Apollo 11 be unable to land on the moon, then Apollo 12 would be launched in September and the remaining Apollo shots would follow at 2V2-month Inter vals until the landing was achieved. Four-Month Interval Gnce the landing is made suc cessfully, any and all remaining shots would shift to a four- month interval between shots, it is Other articles in the series will deal with current theories of the interior of moon, the proh lems of guarding against any 'lunar bugs" that may possibly exist on the moon, and the pe culiar problems the astronauts may face as they try to walk on he moon without falling flat on their faces. This article and the one above deal with the broad aspects of the Apollo 11 timeline on a day-by-day breakdown of the flight plan.
