  • Astronaut John W. Young - "LM to Buzz Moon - Apollo X Rehearses For Lunar Landing"
    day Apollo X flight is scheduled for launch from Kennedy Space Center Florida with Thomas P Stafford as spacecraft commander John W Young as command module pilot and Eugene Cernan as lunar module pilot The backup crew is L Gordon Cooper Donn F Eisele and Edgar D Mitchell The purpose of the flight is to provide additional experience in combined system operation during the 3 day trip to the vicinity of the Moon and in lunar orbit With the exception of the actual landing of the lunar module on the lunar surface the mission plan is the same as for the lunar landing mission While the spacecraft circles the Moon at an altitude of about 60 miles Stafford and Cernan in the lunar module will separate from the command and service modules approach twice to within about 10 miles of one of the preselected Apollo landing sites then rejoin Young in the command module in maneuvers similar to those performed in Earth orbit by Apollo IX Backing Out of Garage Drawing shows a complete Apollo spacecraft pulling away from the S IVB third stage after translunar injection in the Apollo X mission After a good translunar injection is verified the command service module will turn around and dock with the lunar module and extract the LM from the spacecraft LM adapter After insertion into lunar orbit Apollo X commander Tom Stafford and lunar module pilot Gene Cernan will man the LM and separate for a descent to within eight miles of the lunar surface while command module pilot John Young waits for their return in a rehearsal of a lunar orbit rendezvous following a manned lunar landing The closest approach to the surface will be at pericynthion of the lunar module transfer orbit Because of propellant limitation in the ascent

  • Astronaut John W. Young - "Apollo X to 'Sort Unknowns' Before Lunar Landing Flight"
    had in the past sort out all the unknowns and actually pave the whole way for the lunar landing mission We ll do everything exactly as the landing mission except the final descent landing on the surface and the ascent into orbit We are working with the Apollo XI crew as a team really Apollo X is scheduled for a May 18 launch from Kennedy Space Center Launch Complex B for an eight day lunar orbit mission with an all up Apollo spacecraft stack Apollo Spacecraft Program manager George Low describes Apollo X as doing everything that we did in Apollo IX only in lunar orbit During the seven and a half hour period of the Apollo X rendezvous sequence when Snoopy will be as far away as 350 miles from Charlie Brown command module pilot John Young will be prepared to maneuver in to rescue the LM John is not up there waiting for us to come back said lunar module pilot Gene Cernan He s up there spring loaded within seconds after our burn misfires to come and get us because you don t wait maybe a rev or an extra couple of hours The lunar module does not have the consumables to wait that long for someone to come and get you We ve often thought of tying a 350 mile steel clothesline between the two vehicles just to make sure quipped Cernan but we ve certainly given that up Apollo X will spend more than 61 hours in lunar orbit and the transearth flight time will be just over 53 hours Touching on the culinary aspect of Apollo X Cernan said There s something about eating with a spoon that automatically makes the food taste just a little bit better to me than sucking it out

  • Astronaut John W. Young - "Apollo X "go ahead" despite difficulties"
    May 5 The CDDT is a full dress rehearsal for the final count with cryogenic fueling of the launch vehicle performed during the wet portion and fueling simulated during the dry portion The flight crew will participate during the dry portion of the CDDT as they would on launch day The Apollo X crewmen held a conference Saturday at MSC where they discussed various aspects of their eight day mission This flight will spend approximately 61 hours in lunar orbit three times longer than Apollo VIII and probably as long as the Apollo XI landing mission One of the most important aspects of this flight in addition to checking systems operations is the data to be brought back from the two LM passes close to the Moon s surface There is a possibility of aborting the first landing mission unless we bring back the data to show what we have for altitude tracking on the lunar surface said Commander Tom Stafford From 50 000 feet we will be able to see craters that could get the LM in trouble It will be on the second day of lunar orbit that the two vehicles undock The crew remarked on the difficulty of maneuvering the sections in orbit with a maximum separation of 350 miles I ve never really been involved in anything that has required as great an amount of coordination and team work as to work with two vehicles in a lunar environment said LM Pilot Gene Cernan He and Stafford will work together in the LM while CSM Pilot John Young operates the command controls Assuming all systems check out stable in Apollo X the Apollo XI lunar landing will go in July This vehicle is presently in the KSC Vehicle Assembly Building undergoing preparations for the launch The

  • Astronaut John W. Young - "Apollo 10 plans first color TV from outer space"
    the first live color pictures of space through the major television networks next week The new camera equipment was finally approved during the recent manned Countdown Demonstration Test and approximateIy 12 transmission opportunities were inserted into the flight plan We hope to be able to share with you some of the experiences and things that go behind the gee whiz and golly isn t that beautiful said Lunar Module Pilot Gene Cernan The camera is designed for use only in the Command Module and no LM television color or black and white is planned until Apollo 11 Because of the rapid development cycle of color it is considered to be experimental in nature and will be backed up by a black and white system The color wheel system was selected to adapt a Westinghouse built black and white camera for Apollo 10 It weighs about 12 pounds and is equipped with a zoom type lens adaptable for close up and wide angle shots The system also includes a three inch monitor inside the capsule giving the operator a black and white image of what he is transmitting 1 2 3 4 5 6 7 8 9 10 11 12 13

  • Astronaut John W. Young - "Color TV from space entertains and enlightens"
    the multi colored earth and growth of the grey brown moon mass Serious one moment and hilarious the next the Tom John and Gene show scored high on entertainment An unofficial tape recording of the popular Fly me to the Moon and Up up and away provided background music for the documentary For the benefit of interested geologists each crewmen filmed part of the moon s face and described what he was seeing The new color equipment worked with amazing precision enabling the crew to record the moon s wandering rilles craters and valleys as well as astronaut antics in the spacecraft A feeling of closeness to mission progress was generated by the real time photography and a better understanding of such phenomenon as weightlessness and disorientation in space was gained from the crew s simple demonstrations The idea of sharing the experience of spaceflight was supported wholeheartedly by Apollo 10 personnel and at the end of the mission Gene Cernan said he hoped they had given the millions of people of the world more of a part in the history being made this day and age Mission planners have announced their intentions to include live color transmissions in the

  • Astronaut John W. Young - "Apollo 10 splashes into ocean on target"
    on their trans lunar course As testimony to the amazing accuracy of the mission planning and flight navigation landing time was predicted six months ago within 35 seconds of actual splashdown the entire mission operated within minutes of the flight schedule and only two out of several planned mid course corrections were deemed necessary The first of these corrections on the trans lunar coast involved a service propulsion system burn of seven seconds at about 2 30 Monday afternoon Increased pre flight precautions left the Apollo 10 crew in extremely good physical condition the only complaint being some slightly unsettled stomachs from hydrogen in the drinking water Tuesday was a relatively quiet day as Apollo 10 continued on its TLC offering both scheduled and unscheduled television along the way Lunar orbit insertion was accomplished about 12 30 p m on Wednesday The remainder of the afternoon was spent on lunar photography systems checks and generally accustoming the mission personnel and crew to intermittent losses of communication The mission s first obstacle was encountered shortly after 10 Thursday morning when Stafford and Cernan entered the LM for the first time and were greeted by a flurry of snowlike fiberglass released from a rent in the CSM hatch The fibers which caused some skin and eye irritation for the astronauts were also clogging a 1 4 inch tunnel vent delaying the undocking maneuver until the problem was cleared up Plans are already in the works for a change in insulation before the next flight Tension rose again just before the schedule separation behind the moon when Snoopy shifted about 3 degrees placing a slight strain on the docking mechanism However when the group reappeared Charlie Brown was still in his 69 mile circular orbit and Snoopy was flying low The LM crew tackled dozens of tracking photography and observation assignments on its low passes while Young worked to keep communications open between the divided craft and stood ready for any emergency While communications both vocal and high bit rate data were minimal during the first low pass satisfactory linkage was apparently restored for Snoopy s second dive However this is the type of anomoly that will undergo careful study before a go ahead is given for Apollo 11 A more dramatic but reportedly less dangerous event occurred after the first pass just as Stafford and Cernan prepared to jettison the LM s descent stage As the vehicle burst apart throwing the descent stage into lunar orbit as planned the L M cabin was seized by a series of violent gyrations which sent the crew s heart rates soaring Stafford took over when the rolling began and stabilized the craft manually The problem has been traced to a control switch accidentally left in the wrong position Flight controllers agree that the crew was in no immediate danger during the shake up Eight hours and four revolutions after undocking Snoopy fired his ascent engines and began to maneuver toward Charlie Brown That rendezvous was

  • Astronaut John W. Young - "Apollo 10 returned navigation, site data"
    the landing sites and on navigation in the Moon s gravitational field Also much was learned about crew procedures and their workload factors he said The mission of Apollo 10 was to sort the unknowns in lunar environment before the first Moon landing now scheduled for July 20 While the decision to hold to that schedule is forthcoming some of the considerations from May s flight which will influence the decision are being discussed One change to be made as a result of Apollo 10 will be a delay in the lunar module 5 s descent orbit insertion for one revolution in order to pick up high bit data from the OMNI antennas through Goldstone Among the major unknowns to be checked by Apollo 10 were the condition of the proposed landing sites and the reliability of the tracking systems so necessary to a successful landing Much of this information on selected lunar geographical points will come from the mission s 2000 still pictures 18 rolls of movie film and recorded observations by the crew Based on the results of the Apollo 10 landing system flight planners feel they can target the LM5 right over landing site 2 prime target for the July effort However another Apollo 10 discovery will have to be taken into consideration There is a Mascon a dense concentration of matter located in Smythe s Sea which accelerated trajectory and caused it to pass about four miles south of the prime target This data is being analysed for a better understanding of the moon s shape and peculiarities While the debriefing and data analysis continue the crew and spacecraft for Apollo 11 are being checked out for a July 16 launch from pad 39A at Kennedy Space Center Rehearsals for the all important landing maneuver are
