===Launch and flight to lunar orbit=== | |||
Apollo 14 launched during heavy cloud cover and the Saturn V booster quickly disappeared from view. NASA's long-range cameras, based 60 miles south in ], had a clear shot of the remainder of the launch. Following the launch, the ] at ] was visited by ] ], ] of ], and his wife, ]. | |||
At the beginning of the mission, the ] ''Kitty Hawk'' had difficulty achieving capture and docking with the ] ''Antares''. Repeated attempts to dock went on for 1 hour and 42 minutes, until it was suggested that Roosa hold ''Kitty Hawk'' against ''Antares'' using its thrusters, then the docking probe would be retracted out of the way, hopefully triggering the docking latches. This attempt was successful, and no further docking problems were encountered during the mission. | |||
===Lunar descent=== | |||
After separating from the Command Module in lunar orbit, the LM ''Antares'' also had two serious problems. First, the LM computer began getting an ABORT signal from a faulty switch. NASA believed that 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 ] to separate from the ] and climb back into orbit. NASA and the software teams at the ] scrambled to find a solution, and determined the fix would involve reprogramming the flight software to ignore the false signal. The ] were transmitted to the crew via voice communication, and Mitchell manually entered the changes (amounting to over 80 keystrokes on the LM computer pad) just in time. | |||
A second problem occurred during the powered descent, when the LM ] 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 (this was not a result of the modifications to the ABORT command; rather, the post-mission report indicated it was an unrelated bug in the radar's operation). After the astronauts cycled the landing radar breaker, the unit successfully acquired a signal near {{convert|18000|ft|m}}, again just in time. Shepard then manually landed the LM closer to its intended target than any of the other six Moon landing missions. Mitchell believed that Shepard would have continued with the landing attempt without the radar, using the LM inertial guidance system and visual cues. A post-flight review of the descent data showed the inertial system alone would have been inadequate, and the astronauts probably would have been forced to abort the landing as they approached the surface. | |||
===Lunar surface operations=== | |||
] left on the Moon by Apollo 14]] | |||
Shepard and Mitchell named their landing site ''Fra Mauro Base'', and this designation is recognized by the ] (depicted in Latin on lunar maps as ''Statio Fra Mauro''). | |||
Shepard's first words, after stepping onto the lunar surface were, "And it's been a long way, but we're here." Unlike ] on ] and ] on Apollo 12, Shepard had already stepped off the LM footpad and was a few yards (meters) away before he spoke. | |||
Shepard's moonwalking suit was the first to utilize red stripes on the arms and legs and on the top of the lunar EVA sunshade "hood," so as to allow easy identification between the commander and LM pilot on the surface;<ref>{{cite journal |last=von Braun |first=Wernher |authorlink=Wernher von Braun |title=Space Suits—from Pressurized Prison to Mini-Spacecraft |date=July 1972 |journal=] |page=121 |url=https://books.google.com/books?id=WZ6okH8FCs4C&lpg=PA121&dq=space%20suits%20red%20bands&pg=PA121#v=onepage&q=space%20suits%20red%20bands&f=false |accessdate=July 17, 2013}}</ref> on the ] pictures, it had been almost impossible to distinguish between the two crewmen, causing a great deal of confusion. This feature was included on ]'s Apollo 13 suit; because no landing was made on that mission, Apollo 14 was the first to make use of it. This feature was used for the remaining Apollo missions, and for the EVAs of ] flights afterwards, and it is still in use today on both the U.S. and Russian ]s on the ]. | |||
After landing in the Fra Mauro formation—the destination for Apollo 13—Shepard and Mitchell took two moonwalks, adding new ]<ref>Brzostowski and Brzostowski, pp 414-416</ref> to the by now familiar ] (ALSEP), and using the ] (MET), a pull-cart for carrying equipment and samples, nicknamed "lunar rickshaw". Roosa, meanwhile, took pictures from on board Command Module ''Kitty Hawk'' in lunar orbit. | |||
The second moonwalk, or EVA, was intended to reach the rim of the {{convert|1000|ft|m|adj=on}} wide Cone Crater. The two astronauts were not able to find the rim amid the rolling terrain of the crater's slopes. They became physically exhausted from the attempt and with their suits' oxygen supplies starting to run low, the effort was called off. Later analysis, using the pictures that they took, determined that they had come within an estimated {{convert|65|ft|m}} of the crater's rim. Images from the ] (LRO) show the tracks of the astronauts and the MET come to within 30 m of the rim.<ref>{{cite web |url=http://lroc.sese.asu.edu/news/index.php?/archives/91-Trail-of-Discovery-at-Fra-Mauro.html |title = Trail of Discovery at Fra Mauro |last=Lawrence |first=Samuel |date=August 19, 2009 |work=Featured Images |publisher=LROC News System |location=Tempe, Arizona}}</ref> | |||

Shepard and Mitchell deployed and activated various scientific instruments and experiments and collected almost {{convert|100|lb|kg}} of lunar samples for return to Earth. Other Apollo 14 achievements included the only use of MET; longest distance traversed by foot on the lunar surface; first use of shortened lunar orbit rendezvous techniques; and the first extensive orbital science period conducted during CSM solo operations. | |||
The astronauts also engaged in less serious activities on the Moon. Shepard brought along a ] which he could attach to the handle of a lunar excavation tool, and two golf balls, and took several one-handed swings (due to the limited flexibility of the EVA suit). He exuberantly exclaimed that the second ball went "miles and miles and miles" in the low lunar ], but later estimated the distance as {{convert|200|to|400|yd|sp=us}}. Mitchell then threw a lunar scoop handle as if it were a ]. | |||
===Return, splashdown and quarantine=== | |||
] | |||
On the way back to Earth, the crew conducted the first U.S. materials processing experiments in space. | |||
The Command Module ''Kitty Hawk'' splashed down in the South Pacific Ocean on February 9, 1971 at 21:05 , approximately {{convert|760|nmi|km}} south of ]. After recovery by the ship ], the crew was flown to ] in ] for a reception before being flown on a ] cargo plane to ]. The Apollo 14 astronauts were the last lunar explorers to be ] on their return from the Moon. | |||
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 widely distributed around the world as commemorative ]s.<ref>{{Cite web| url=http://nssdc.gsfc.nasa.gov/planetary/lunar/moon_tree.html| title=The 'Moon Trees'| first=David R.| last=Williams| publisher=NASA| work=]| date=28 July 2009| accessdate=July 17, 2013}}</ref> | |||
