Launch and flight to lunar orbit Apollo 14 launched from Launch Complex 39-A at KSC at 4:03:02 pm (21:03:02 UTC), January 31, 1971. After the vehicle reached orbit, the
S-IVB third stage shut down, and the astronauts performed checks of the spacecraft before restarting the stage for translunar injection (TLI), the burn that placed the vehicle on course for the Moon. After TLI, the CSM separated from the S-IVB, and Roosa performed the transposition maneuver, turning it around in order to dock with the LM before the entire spacecraft separated from the stage. Roosa, who had practiced the maneuver many times, hoped to break the record for the least amount of propellant used in docking. But when he gently brought the modules together, the docking mechanism would not activate. He made several attempts over the next two hours, as mission controllers huddled and sent advice. If the LM could not be extracted from its place on the S-IVB, no lunar landing could take place, and with consecutive failures, the Apollo program might end. Mission Control proposed that they try it again with the docking probe retracted, hoping the contact would trigger the latches. This worked, and within an hour the joined spacecraft had separated from the S-IVB. The stage was set on a course to impact the Moon, which it did just over three days later, causing the Apollo 12 seismometer to register vibrations for over three hours. The crew settled in for its voyage to Fra Mauro. At 60:30 Ground Elapsed Time, Shepard and Mitchell entered the LM to check its systems; while there they photographed a wastewater dump from the CSM, part of a particle contamination study in preparation for
Skylab. Two midcourse corrections were performed on the translunar coast, with one burn lasting 10.19 seconds and one lasting 0.65 seconds.
Lunar orbit and descent At 81:56:40.70 into the mission (February 4 at 1:59:43 am EST; 06:59:43 UTC), the Service Propulsion System engine in the SM was fired for 370.84 seconds to send the craft into a lunar orbit with
apocynthion of and
pericynthion of . A second burn, at 86:10:52 mission time, sent the spacecraft into an orbit of by . This was done in preparation for the release of the LM
Antares. Apollo 14 was the first mission on which the CSM propelled the LM to the lower orbit—though Apollo 13 would have done so had the abort not already occurred. This was done to increase the amount of hover time available to the astronauts, a safety factor since Apollo 14 was to land in rough terrain. After separating from the command module in lunar orbit, the LM
Antares had two serious problems. First, the LM computer began getting an ABORT signal from a faulty switch. NASA believed the computer might be getting erroneous readings like this if a tiny ball of solder had shaken loose and was floating between the switch and the contact, closing the circuit. The immediate solution – tapping on the panel next to the switch – did work briefly, but the circuit soon closed again. If the problem recurred after the descent engine fired, the computer would think the signal was real and would initiate an auto-abort, causing the
ascent stage to separate from the
descent stage and climb back into orbit. NASA and the software teams at the
Massachusetts Institute of Technology scrambled to find a solution. The software was hard-wired, preventing it from being updated from the ground. The fix made it appear to the system that an abort had already happened, and it would ignore incoming automated signals to abort. This would not prevent the astronauts from piloting the ship, though if an abort became necessary, they might have to initiate it manually. Mitchell entered the changes with minutes to go until planned ignition. A second problem occurred during the powered descent, when the LM
landing radar failed to lock automatically onto the Moon's surface, depriving the navigation computer of vital information on the vehicle's altitude and vertical descent speed. After the astronauts cycled the landing radar breaker, the unit successfully acquired a signal near . Mission rules required an abort if the landing radar was out at , though Shepard might have tried to land without it. With the landing radar, Shepard steered the LM to a landing which was the closest to the intended target of the six missions that landed on the Moon.
Lunar surface operations Shepard stated, after stepping onto the lunar surface, "And it's been a long way, but we're here." as well as setting up and loading the MET. These activities were televised back to Earth, though the picture tended to degenerate during the latter portion of the EVA. Mitchell deployed the ASE's geophone lines, unreeling and emplacing the two lines leading out from the ALSEP's Central Station. He then fired the thumper explosives, vibrations from which would give scientists back on Earth information about the depth and composition of the lunar regolith. Of the 21 thumpers, five failed to fire. On the way back to the LM, the astronauts collected and documented lunar samples, and took photographs of the area. Images from the
Lunar Reconnaissance Orbiter (LRO) show the tracks of the astronauts and the MET come to within 30 m of the rim. The difficulties faced by Shepard and Mitchell would emphasize the need for a means of transportation on the lunar surface with a navigation system, which was met by the Lunar Roving Vehicle, already planned to fly on Apollo 15. Once the astronauts returned to the vicinity of the LM and were again within view of the television camera, Shepard performed a stunt he had been planning for years in the event he reached the Moon, and which is probably what Apollo 14 is best remembered for. Shepard brought along a
Wilson six iron golf club head, which he had modified to attach to the handle of the contingency sample tool, and two golf balls. Shepard took several one-handed swings (due to the limited flexibility of the EVA suit) and exuberantly exclaimed that the second ball went "miles and miles and miles" in the low lunar gravity. Mitchell then threw a lunar scoop handle as if it were a
javelin. The "javelin" and one of the golf balls wound up in a crater together, with Mitchell's projectile a bit further. In an interview with Ottawa Golf, Shepard stated the other landed near the ALSEP. The second EVA lasted 4 hours, 34 minutes, 41 seconds. Shepard brought back the club, gave it to the
USGA Museum in New Jersey, and had a replica made which he gave to the
National Air and Space Museum. In February 2021, to commemorate Apollo 14's 50th anniversary, imaging specialist
Andy Saunders, who had previously worked to produce the clearest image of
Neil Armstrong on the Moon, produced new, digitally enhanced images that were used to estimate the final resting places of the two balls that Shepard hit - the first landed approximately 24 yards from the "tee", while the second managed 40 yards. showing Shepard taking a couple of
golf swings Lunar samples " rock (Lunar Sample 14321) was the third largest rock collected during the Apollo program. A total of of Moon rocks, or lunar samples, were brought back from Apollo 14. Most are
breccias, which are rocks composed of fragments of other, older rocks. Breccias form when the heat and pressure of meteorite impacts fuse small rock fragments together. There were a few basalts that were collected in this mission in the form of clasts (fragments) in breccia. The Apollo 14 basalts are generally richer in aluminum and sometimes richer in potassium than other lunar basalts. Most
lunar mare basalts collected during the Apollo program were formed from 3.0 to 3.8 billion years ago. The Apollo 14 basalts were formed 4.0 to 4.3 billion years ago, older than the volcanism known to have occurred at any of the mare locations reached during the Apollo program. Some geologists were pleased enough with the close approach to Cone crater to send a case of scotch to the astronauts while they were in post-mission quarantine, though their enthusiasm was tempered by the fact that Shepard and Mitchell had documented few of the samples they brought back, making it hard and sometimes impossible to discern where they came from. Others were less happy;
Don Wilhelms wrote in his book on the geological aspects of Apollo, "the golf game did not set well with most geologists in light of the results at Cone crater. The total haul from the rim-flank of Cone ... was 16 Hasselblad photographs (out of a mission total of 417), six rock-size samples heavier than 50 g, and a grand total of 10 kg of samples, 9 kg of which are in one rock (
sample 14321 [i.e.,
Big Bertha]). That is to say, apart from 14321 we have less than 1 kg of rock—962 g to be exact—from what in my opinion is the most important single point reached by astronauts on the Moon." Geologist
Lee Silver stated, "The Apollo 14 crews did not have the right attitude, did not learn enough about their mission, had the burden of not having the best possible preflight photography, and they weren't ready." In their sourcebook on Apollo, Richard W. Orloff and David M. Harland doubted that if Apollo 13 had reached the Moon, Lovell, and Haise, given a more distant landing point, could have got as close to Cone crater as Shepard and Mitchell did. In January 2019 research showed that Big Bertha, which weighs , has characteristics that make it likely to be a terrestrial (Earth) meteorite. Granite and quartz, which are commonly found on Earth but very rarely found on the Moon, were confirmed to exist on Big Bertha. To find the sample's age, the research team from
Curtin University looked at bits of the mineral zircon embedded in its structure. "By determining the age of zircon found in the sample, we were able to pinpoint the age of the host rock at about four billion years old, making it similar to the oldest rocks on Earth," researcher Alexander Nemchin said, adding that "the chemistry of the zircon in this sample is very different from that of every other zircon grain ever analyzed in lunar samples, and remarkably similar to that of zircons found on Earth." This would mean Big Bertha is both the first discovered terrestrial meteorite and the oldest known Earth rock.
Lunar orbit operations Roosa spent almost two days alone aboard
Kitty Hawk, performing the first intensive program of scientific observation from lunar orbit, much of which was intended to have been done by Apollo 13. After
Antares separated and its crew began preparations to land, Roosa in
Kitty Hawk performed an SPS burn to send the CSM to an orbit of approximately , and later a
plane change maneuver to compensate for the rotation of the Moon. Roosa took pictures from lunar orbit. The Lunar Topographic Camera, also known as the Hycon camera, was supposed to be used to image the surface, including the Descartes Highlands site being considered for Apollo 16, but it quickly developed a fault with the shutter that Roosa could not fix despite considerable help from Houston. Although about half of the photographic targets had to be scrubbed, Roosa was able to obtain photographs of Descartes with a Hasselblad camera and confirm that it was a suitable landing point. Roosa also used the Hasselblad to take photographs of the impact point of Apollo 13's S-IVB near
Lansburg B crater. After the mission, troubleshooting found a tiny piece of aluminum contaminating the shutter control circuit, which caused the shutter to operate continuously. Roosa was able to see sunlight glinting off
Antares and view its lengthy shadow on the lunar surface on Orbit 17; on Orbit 29 he could see the sun reflecting off the ALSEP. He also took astronomical photographs, of the
Gegenschein, and of the
Lagrangian point of the Sun-Earth system that lies beyond the Earth (L), testing the theory that the Gegenschein is generated by reflections off particles at L. Performing the
bistatic radar experiment, he also focused
Kitty Hawk VHF and S-band transmitters at the Moon so that they would bounce off and be detected on Earth in an effort to learn more about the depth of the lunar regolith.
Return, splashdown and quarantine Antares lifted off from the Moon at 1:48:42 pm EST On the final evening in space, the crew conducted a press conference, with the questions submitted to NASA in advance and read to the astronauts by the CAPCOM. The command module
Kitty Hawk splashed down in the South Pacific Ocean on February 9, 1971, at 21:05 [UTC], approximately south of
American Samoa. After recovery by the ship
USS New Orleans, the crew was flown to
Pago Pago International Airport in
Tafuna, then to Honolulu, then to
Ellington Air Force Base near Houston in a plane containing a
Mobile Quarantine Facility trailer before they continued their quarantine in the
Lunar Receiving Laboratory. They remained there until their release from quarantine on February 27, 1971. The Apollo 14 astronauts were the last lunar explorers to be quarantined on their return from the Moon. They were the only Apollo crew to be quarantined both before and after the flight. Roosa, who worked in forestry in his youth, took several hundred tree seeds on the flight. These were germinated after the return to Earth, and were widely distributed around the world as commemorative
Moon trees. Some seedlings were given to state forestry associations in 1975 and 1976 to mark the
United States Bicentennial. == Mission insignia ==
