On the mission patch, a wide, light blue border carries the word apollo at the top and the crew names around the bottom. The patch is trimmed in gold. The insignia was designed by Allen Stevens of Rockwell International. 22 'Space music mystery' edit In February 2016 Discovery Channel broadcast a tv show suggesting that the mission witnessed mysterious or alien signals while on the far side of the moon. 23 The astronomers mention the odd whistling sound that lasted nearly an hour. It was speculated that this is an evidence for ufo writing coverup. According to space journalist James Oberg the sound was most probably radio interference between the command Module and the lunar Module landing vehicles.
The idea was to give children a way to identify with the mission by using humor. 19 20 Hardware disposition edit The command Module Charlie brown is currently on loan to the Science museum in London, where it is on display. Charlie brown' s Service module (SM) was jettisoned just before re-entry and burned up in the earth's atmosphere. After translunar injection, the saturn V's s-ivb third stage was accelerated past Earth escape velocity and became a derelict object where as of 2015, it remains in a heliocentric orbit. 21 Mission insignia edit The shield-shaped emblem for the flight shows a large, three-dimensional Roman numeral X sitting on the moon's surface, in Stafford's words, "to show that we had left our mark." Although it did not land on the moon, the prominence of the. A csm circles the moon as an lm ascent stage flies up from its low pass over the lunar surface with its engine firing. The earth is visible in the background.

The fueled lm weighed 30,735 pounds (13,941 kg compared to 33,278 pounds (15,095 kg) for the Apollo 11 lm which made the first landing. 12 Craig Nelson wrote in how his book rocket Men that nasa took special precaution to ensure Stafford and Cernan would not attempt to make the first landing. Nelson"d Cernan as saying "A lot of people thought about the kind of people we were: 'don't give those guys an opportunity to land, 'cause they might!' so the ascent module, the part we lifted off the lunar surface with, was short-fueled. The fuel tanks weren't full. So had we literally tried to land on the moon, we couldn't have gotten off." 13 14 In his own memoir, cernan wrote "Our lander, lm-4.was still too heavy to guarantee safe margins for a moon landing." 15 After being jettisoned, Snoopy's ascent stage engine. 8 16 The Apollo 11 ascent stage was left in lunar orbit to eventually crash; all subsequent ascent stages were intentionally steered into the moon to obtain readings from seismometers placed on the surface, except for the one on Apollo 13, which did not land.
16 Snoopy' s ascent stage orbit was not tracked after 1969, and its current location is unknown. In 2011, a group of amateur astronomers in the uk started a project to search for. Splashdown occurred in the pacific Ocean on may 26, 1969, at 16:52:23 utc, about 400 nautical miles (740 km) east of American Samoa. The astronauts were recovered by uss princeton, and subsequently flown to pago pago International Airport in Tafuna for a greeting reception, before being flown on a c-141 cargo plane to honolulu. After Apollo 10, nasa required astronauts to choose more "dignified" names for their Command and Lunar Modules. This proved unenforceable: Apollo 16 astronauts young, mattingly and duke chose casper, as in Casper the Friendly Ghost, for their Command Module name.
Except for this final stretch, the mission was designed to duplicate how a landing would have gone, both in space and for ground control, putting nasa's flight controllers and extensive tracking and control network through a rehearsal.

Apollo 10 was the first mission to carry a color television camera inside the spacecraft, and made the first live color tv transmissions from space. Lm snoopy containing Stafford and Cernan, as inspected by young after separation from Charlie brown After reaching lunar orbit three days later, young remained in the command Module (CM) Charlie brown while Stafford and Cernan entered the lm snoopy and flew it separately.
The lm crew performed the descent orbit insertion maneuver by firing their descent engine, and tested their craft's landing radar as they approached the 50,000-foot (15,000-meter) altitude where powered descent would begin on Apollo. They surveyed the landing site in the sea of Tranquility, then separated the descent stage and fired the ascent engine to return to Charlie brown. The descent stage was left in orbit, but eventually crashed onto the lunar surface because of the moon's non-uniform gravitational field; its location was not tracked. Upon descent stage separation and ascent engine ignition, the lunar Module began to roll violently because the crew accidentally duplicated commands into the flight computer which took the lm out of abort mode, the correct configuration for this maneuver. 11 The live network broadcasts caught Cernan and Stafford uttering several expletives before regaining control of the. Cernan has said he observed the horizon spinning eight times over, indicating eight rolls of the spacecraft under ascent engine power. While the incident was downplayed by nasa, the roll was just several revolutions from being unrecoverable, which would have resulted in the lm crashing into the lunar surface. 11 The ascent stage was loaded with the amount of fuel it would have had remaining if it had lifted off from the surface and reached the altitude at which the Apollo 10 ascent stage fired.

6 deke slayton wrote in his memoirs that cooper and Donn. Eisele were never intended to rotate to another mission as both were out of favor with nasa management for various reasons (Cooper for his lax attitude towards training and Eisele for incidents aboard Apollo 7 and an extramarital affair ) and were assigned to the. Cooper, Slayton noted, had a very small chance of receiving the essay Apollo 13 command if he did an outstanding job with the assignment, which he did not. Eisele, despite his issues with management, was always intended for future assignment to the Apollo Applications Program (which was eventually cut down to only the skylab component) and not a lunar mission. 7 Objectives edit earthrise video captured by Apollo 10 crew This dress rehearsal for a moon landing brought the Apollo lunar Module.4 nautical miles (15.6 km) from the lunar surface, at the point where powered descent would begin summary on the actual landing.

Apollo. Young was also backup commander of Apollo 13 and Cernan was backup commander of Apollo. The Apollo 10 crew are also the humans who have traveled the farthest away from home, some 408,950 kilometers (220,820 nmi) from their homes and families in houston. 4 While most Apollo missions orbited the moon at the same 111 kilometers (60 nmi) from the lunar surface, the distance between the earth and moon varies by about 43,000 kilometers (23,000 nmi between perigee and apogee, throughout the year, and the earth's rotation make the distance. The Apollo 10 crew reached the farthest point in their orbit around the far side of the moon at about the same time earth's rotation put houston nearly a full Earth diameter away. 5 by the normal rotation in place during Apollo, the backup crew would have been scheduled to fly on Apollo. However, Alan Shepard, then number 2 at the Astronaut office, gave himself the Apollo 13 command slot instead. Gordon cooper,., commander of the Apollo 10 backup crew, was enraged and resigned from nasa. Later, Shepard's crew was forced to switch places with Jim lovell 's tentative apollo 14 crew.
