scheduled for Apollo 15 and later. Additionally, a navigation exercise was done to simulate a return to Earth following a loss of communications. All were successful. During his rest periods on the voyage, Mitchell conducted ESP experiments without NASA's knowledge or sanction, attempting by prearrangement to send images of cards he had brought with him to four people on Earth. He stated after the mission that two of the four had gotten 51 out of 200 correct (the others were less successful), whereas random chance would have dictated 40. 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 The mission insignia is an oval depicting the Earth and the Moon, and an astronaut pin drawn with a comet trail. The pin is leaving Earth and is approaching the Moon. A gold band around the edge includes the mission and astronaut names. The designer was Jean Beaulieu, who based it on a sketch by Shepard, who had been head of the Astronaut Office and meant the pin to symbolize that through him, the entire corps was in spirit flying to the Moon. The backup crew spoofed the patch with its own version, with revised artwork showing a Wile E. Coyote cartoon character depicted as gray-bearded (for Shepard, who was
