Official NASA Biography as of June 2016:Alfred Merrill Worden
NASA Astronaut (former)

PERSONAL DATA: The son of Merrill and Helen Worden, he was born in Jackson, Michigan, on February 7, 1932. Married to Jill Lee Worden (Hotchkiss). Three children. Recreational interests include bowling, water skiing, golf and racquet ball.

EDUCATION: Attended Dibble, Griswold, Bloomfield and East Jackson grade schools and completed his secondary education at Jackson High School: Received a bachelor of military science degree from the United States Military Academy at West Point, New York, in 1955 and master of science degrees in Astronautical/Aeronautical Engineering and Instrumentation Engineering from the University of Michigan in 1963. Received honorary doctorate of science in Astronautical Engineering from University of Michigan in 1971.

EXPERIENCE: Worden was graduated from the United States Military Academy in June 1955 and, after being commissioned in the Air Force, received flight training at Moore Air Base, Texas; Laredo air Force Base, Texas; and Tyndall Air Force Base, Florida.

Prior to his arrival for duty at the Johnson Space Center, he served as an instructor at the Aerospace Research Pilots School-- from which he graduated in September 1965. He is also a February 1965 graduate of the Empire Test Pilots School in Farnborough, England.

He attended Randolph Air Force Base Instrument Pilots Instructor School in 1963 and served as a pilot and armament officer from March 1957 to May 1961 with the 95th Fighter Interceptor Squadron at Andrews Air Force Base, Maryland.

He has logged more than 4,000 hours flying time--which includes 2,500 hours in jets.

NASA EXPERIENCE: Worden was one of the 19 astronauts selected by NASA in April 1966. He served as a member of the astronaut support crew for the Apollo 9 flight and as backup command module pilot for the Apollo 12 flight.

Worden served as command module pilot for Apollo 15, July 26 - August 7, 1971. His companions on the flight were David R. Scott, spacecraft commander, and James B. Irwin, lunar module commander. Apollo 15 was the fourth manned lunar landing mission and the first to visit and explore the moon's Hadley Rille and Apennene Mountains which are located on the southeast edge of the Mare Imbrium (Sea of Rains). Apollo 15 achievements include: Largest payloads placed in earth and lunar orbits; first scientific instrument module bay flown and operated on an Apollo spacecraft; longest lunar surface stay time (the lunar module, "Falcon," remained on ground for 66 hours and 54 minutes); longest lunar surface EVA (Scott and Irwin logged 18 hours and 35 minutes each during three excursions onto the lunar surface); longest distance traversed on lunar surface; first use of lunar roving vehicle; first use of a lunar surface navigation device (mounted on Rover-1); first subsatellite launched in lunar orbit; and first EVA from a command module during transearth coast.

Scott and Irwin collected approximately 171 pounds of lunar surface materials on their three expeditions onto the lunar surface; and Worden logged 38 minutes in extravehicular activity outside the command module, "Endeavour." In completing his three excursions to "Endeavour's" scientific instrument module bay, Worden retrieved film cassettes from the panoramic and mapping cameras and reported his personal observations of the general condition of equipment housed there. Apollo 15 concluded with a Pacific splashdown and subsequent recovery by the USS OKINAWA. In completing his space flight, Worden logged 295 hours and 11 minutes in space.

During 1972-1973, Worden was Senior Aerospace Scientist at the NASA Ames Research Center, and from 1973 to 1975, he was chief of the Systems Study Division at Ames.

After retirement from active duty in 1975, Worden became President of Maris Worden Aerospace, Inc., and is currently Staff Vice-President of BG Goodrich Aerospace Brecksville, Ohio.

Official Biography

NAME: Alfred M. Worden

BIRTHPLACE AND DATE: Worden was born February 7, 1932, in Jackson, Michigan.

EDUCATION: Bachelor of Science degree in military science from the U.S. Military Academy in 1955. Master of Science degrees in astronautical/aeronautical engineering and instrumentation engineering from the University of Michigan in 1963.

EXPERIENCE: After graduation, Worden was commissioned in the U.S. Air Force and received flight training at Moore Air Force Base, Texas, and Tyndall Air Force Base, Florida. He served as a pilot and armament officer with the 95th Fighter Interceptor Squadron at Andrews Air Force Base, Maryland. In 1965 he was graduated from both the Empire Test Pilots School, Farnborough, England, and from the Aerospace Research Pilots School in California. He was an instructor at the latter when NASA selected him as an astronaut in April 1966.

Worden was backup Command Module pilot on Apollo 12. He was then named to the prime crew of Apollo 15, together with Commander David Scott and Lunar Module pilot Jim Irwin. Apollo 15 launched on July 26, 1971, and Worden orbited the moon alone for three days in the command module Endeavour while Scott and Irwin explored a mountainous region on the edge of the Mare Imbrium. Worden remotely photographed the moon's surface with two special cameras mounted outside the ship. On the homeward journey, Worden took the first deep space EVA moving along handrails on the outside of Endeavour to the rear of the Service Module to retrieve film cassettes from the two cameras.

After Apollo 15, Worden was Senior Aerospace Scientist and later Chief of the Systems Studies Division at NASA's Ames Research Center in California. He left NASA in September 1975 to become Vice President of the High Flight Foundation, under his Apollo 15 co-pilot, James Irwin. He later held executive positions with Jet Electronics and Technology and BF Goodrich Corporation before retiring in 1996..

• Apollo 12 - . Call Sign: Yankee Clipper. Crew: Bean, Conrad, Gordon. Backup Crew: Irwin, Scott, Worden. Payload: Apollo CSM 108 / Apollo LM 6 / ALSEP / S-IVB-507. Mass: 28,790 kg (63,470 lb). Nation: USA. Agency: NASA Houston. Program: Apollo. Class: Moon. Type: Manned lunar spacecraft. Flight: Apollo 12. Spacecraft: Apollo CSM. Duration: 10.19 days. Decay Date: 1969-11-24 . USAF Sat Cat: 4225 . COSPAR: 1969-099A. Apogee: 186 km (115 mi). Perigee: 181 km (112 mi). Inclination: 32.50 deg. Period: 88.19 min.

  Apollo 12 (AS-507)-with astronauts Charles Conrad, Jr., Richard F. Gordon, Jr., and Alan L. Bean as the crewmen-was launched from Pad A, Launch Complex 39, KSC, at 11:22 a.m. EST November 14. Lightning struck the space vehicle twice, at 36.5 seconds and 52 seconds into the mission. The first strike was visible to spectators at the launch site. No damage was done. Except for special attention given to verifying all spacecraft systems because of the lightning strikes, the activities during earth-orbit checkout, translunar injection, and translunar coast were similar to those of Apollo 10 and Apollo 11.

  During the translunar coast astronauts Conrad and Bean transferred to the LM one-half hour earlier than planned in order to obtain full TV coverage through the Goldstone tracking station. The 56-minute TV transmission showed excellent color pictures of the CSM, the intravehicular transfer, the LM interior, the earth, and the moon.

  At 10:47 p.m. EST, November 17, the spacecraft entered a lunar orbit of 312.6 x 115.9 kilometers. A second service propulsion system burn circularized the orbit with a 122.5-kilometer apolune and a 100.6-kilometer perilune. Conrad and Bean again transferred to the LM, where they perfomed housekeeping chores, a voice and telemetry test, and an oxygen purge system check. They then returned to the CM.

  Conrad and Bean reentered the LM, checked out all systems, and at 10:17 p.m. EST on November 18 fired the reaction control system thrusters to separate the CSM 108 (the Yankee Clipper) from the LM-6 (the Intrepid). At 1:55 a.m. EST November 19, the Intrepid landed on the moon's Ocean of Storms, about 163 meters from the Surveyor III spacecraft that had landed April 19, 1967. Conrad, shorter than Neil Armstrong (first man on the moon, July 20), had a little difficulty negotiating the last step from the LM ladder to the lunar surface. When he touched the surface at 6:44 a.m. EST November 19, he exclaimed, "Whoopee! Man, that may have been a small step for Neil, but that's a long one for me."

  Bean joined Conrad on the surface at 7:14 a.m. They collected a 1.9-kilogram contingency sample of lunar material and later a 14.8-kilogram selected sample. They also deployed an S-band antenna, solar wind composition experiment, and the American flag. An Apollo Lunar Surface Experiments Package with a SNAP-27 atomic generator was deployed about 182 meters from the LM. After 3 hours 56 minutes on the lunar surface, the two astronauts entered the Intrepid to rest and check plans for the next EVA.

  The astronauts again left the LM at 10:55 p.m. EST November 19. During the second EVA, Conrad and Bean retrieved the lunar module TV camera for return to earth for a failure analysis, obtained photographic panoramas, core and trench samples, a lunar environment sample, and assorted rock, dirt, bedrock, and molten samples. The crew then examined and retrieved parts of Surveyor III, including the TV camera and soil scoop. After 3 hours 49 minutes on the lunar surface during the second EVA, the two crewmen entered the LM at 2:44 a.m. EST November 20. Meanwhile astronaut Gordon, orbiting the moon in the Yankee Clipper, had completed a lunar multispectral photography experiment and photographed proposed future landing sites.

  At 9:26 a.m. EST November 20, after 31 hours 31 minutes on the moon, Intrepid successfully lifted off with 34.4 kilograms of lunar samples. Rendezvous maneuvers went as planned. The LM docked with the CSM at 12:58 p.m. November 20. The last 24 minutes of the rendezvous sequence was televised. After the crew transferred with the samples, equipment, and film to the Yankee Clipper, the Intrepid was jettisoned and intentionally crashed onto the lunar surface at 5:17 p.m. November 20, 72.2 kilometers southeast of Surveyor III. The crash produced reverberations that lasted about 30 minutes and were detected by the seismometer left on the moon.

  At 3:49 p.m. EST November 21, the crew fired the service propulsion system engine, injecting the CSM into a transearth trajectory after 89 hours 2 minutes in lunar orbit. During the transearth coast, views of the receding moon and the interior of the spacecraft were televised, and a question and answer session with scientists and the press was conducted.

• Apollo 15 - . Call Sign: Endeavour. Crew: Irwin, Scott, Worden. Backup Crew: Brand, Gordon, Schmitt. Payload: Apollo CSM 112/LM 10/ ALSEP/ LRV-1/PFS 1/S-IVB-510. Mass: 30,343 kg (66,894 lb). Nation: USA. Agency: NASA Houston. Program: Apollo. Class: Moon. Type: Manned lunar spacecraft. Flight: Apollo 15. Spacecraft: Apollo CSM. Duration: 12.30 days. Decay Date: 1971-08-07 . USAF Sat Cat: 5351 . COSPAR: 1971-063A. Apogee: 169 km (105 mi). Perigee: 166 km (103 mi). Inclination: 29.68 deg. Period: 87.84 min.

  Apollo 15 (AS-510) with astronauts David R. Scott, Alfred M. Worden, and James B. Irwin aboard was launched from Pad A, Launch Complex 39, KSC, at 9:34 a.m. EDT July 26. The spacecraft and S-IVB combination was placed in an earth parking orbit 11 minutes 44 seconds after liftoff. Activities during earth orbit and translunar injection (insertion into the trajectory for the moon) were similar to those of previous lunar landing missions. Translunar injection was at about 12:30 p.m., with separation of the CSM from the LM/S-IVB/IU at 12:56 p.m. At 1:08 p.m., onboard color TV showed the docking of the CSM with the LM.

  S-IVB auxiliary propulsion system burns sent the S-IVB/IU stages toward the moon, where they impacted the lunar surface at 4:59 p.m. EDT July 29. The point of impact was 188 kilometers northeast of the Apollo 14 landing site and 355 kilometers northeast of the Apollo 12 site. The impact was detected by both the Apollo 12 and Apollo 14 seismometers, left on the moon in November 1969 and February 1971.

  After the translunar coast, during which TV pictures of the CSM and LM interiors were shown and the LM communications and other systems were checked, Apollo 15 entered lunar orbit at 4:06 p.m. EDT July 29.

  The LM-10 Falcon, with astronauts Scott and Irwin aboard, undocked and separated from the Endeavor (CSM 112) with astronaut Worden aboard. At 6:16 p.m. EDT July 30, the Falcon landed in the Hadley-Apennine region of the moon 600 meters north-northwest of the proposed target. About two hours later, following cabin depressurization, Scott performed a 33-minute standup EVA in the upper hatch of the LM, during which he described and photographed the landing site.

  The first crew EVA on the lunar surface began at 9:04 a.m. July 31. The crew collected and stowed a contingency sample, unpacked the ALSEP and other experiments, and prepared the lunar roving vehicle (LRV) for operations. Some problems were encountered in the deployment and checkout of the LRV, used for the first time, but they were quickly resolved. The first EVA traverse was to the Apennine mountain front, after which the ALSEP was deployed and activated, and one probe of a Heat Flow experiment was emplaced. A second probe was not emplaced until EVA-2 because of drilling difficulties. The first EVA lasted 6 hours 33 minutes.

  At 7:49 a.m. EDT August 1, the second EVA began. The astronauts made a maintenance check on the LRV and then began the second planned traverse of the mission. On completion of the traverse, Scott and Irwin completed the placement of heat flow experiment probes, collected a core sample, and deployed the American flag. They then stowed the sample container and the film in the LM, completing a second EVA of 7 hours 12 minutes.

  The third EVA began at 4:52 a.m. August 2, included another traverse, and ended 4 hours 50 minutes later, for a total Apollo 15 lunar surface EVA time of 18 hours 35 minutes.

  While the lunar module was on the moon, astronaut Worden completed 34 lunar orbits in the CSM operating scientific instrument module experiments and cameras to obtain data concerning the lunar surface and environment. X-ray spectrometer data indicated richer abundance of aluminum in the highlands, especially on the far side, but greater concentrations of magnesium in the maria.

  Liftoff of the ascent stage of the LM, the first one to be televised, occurred at 1:11 p.m. EDT August 2. About two hours later the LM and CSM rendezvoused and docked, and film, equipment, and 77 kilograms of lunar samples were transferred from the LM to the CSM. The ascent stage was jettisoned and hit the lunar surface at 11:04 p.m. EDT August 2. Its impact was recorded by the Apollo 12, Apollo 14, and Apollo 15 seismometers, left on the moon during those missions. Before leaving the lunar orbit, the spacecraft deployed a subsatellite, at 4:13 p.m. August 4, in an orbit of 141.3 by 102 kilometers. The satellite would measure interplanetary and earth magnetic fields near the moon. It also carried charged-particle sensors and equipment to detect variations in lunar gravity caused by mascons (mass concentrations).

  A transearth injection maneuver at 5:23 p.m. August 4 put the CSM on an earth trajectory. During the transearth coast, astronaut Worden performed an inflight EVA beginning at 11:32 a.m. August 5 and lasting for 38 minutes 12 seconds. He made three trips to the scientific instrument module (SIM) bay of the SM, twice to retrieve cassettes and once to observe the condition of the instruments in the SIM bay.

  CM and SM separation, parachute deployment, and other reentry events went as planned, but one of the three main parachutes failed, causing a hard but safe landing. Splashdown - at 4:45 p.m. EDT (20:45 GMT), after 12 days 7 hours 12 minutes from launch - was 530 kilometers north of Hawaii and 10 kilometers from the recovery ship U.S.S. Okinawa. The astronauts were carried to the ship by helicopter, and the CM was retrieved and placed on board. All primary mission objectives had been achieved.
