Apollo 10

Apollo 10 was the fourth manned mission in the United States Apollo space program, and the second (after Apollo 8) to orbit the Moon. Launched on May 18, 1969, it was the F mission: a "dress rehearsal" for the first Moon landing, testing all of the components and procedures, just short of actually landing. The Lunar Module (LM) came to within 8.4 nautical miles (15.6 km) of the lunar surface, the point where the powered descent to the lunar surface would begin. Its success enabled the first landing to be attempted on Apollo 11 in July, 1969.

According to the 2002 Guinness World Records, Apollo 10 set the record for the highest speed attained by a manned vehicle at 39,897 km/h (11.08 km/s or 24,791 mph) during the return from the Moon on May 26, 1969.

Due to the use of their names as call signs, the Peanuts characters Charlie Brown and Snoopy became semi-official mascots for the mission.Peanuts creator Charles Schulz also drew some special mission-related artwork for NASA.

Apollo

Apollo (Attic, Ionic, and Homeric Greek: Ἀπόλλων, Apollōn (GEN Ἀπόλλωνος); Doric: Ἀπέλλων, Apellōn; Arcadocypriot: Ἀπείλων, Apeilōn; Aeolic: Ἄπλουν, Aploun; Latin: Apollō) is one of the most important and complex of the Olympian deities in classical Greek and Roman religion and Greek and Roman mythology. The ideal of the kouros (a beardless, athletic youth), Apollo has been variously recognized as a god of music, truth and prophecy, healing, the sun and light, plague, poetry, and more. Apollo is the son of Zeus and Leto, and has a twin sister, the chaste huntress Artemis. Apollo is known in Greek-influenced Etruscan mythology as Apulu.

As the patron of Delphi (Pythian Apollo), Apollo was an oracular god—the prophetic deity of the Delphic Oracle. Medicine and healing are associated with Apollo, whether through the god himself or mediated through his son Asclepius, yet Apollo was also seen as a god who could bring ill-health and deadly plague. Amongst the god's custodial charges, Apollo became associated with dominion over colonists, and as the patron defender of herds and flocks. As the leader of the Muses (Apollon Musegetes) and director of their choir, Apollo functioned as the patron god of music and poetry. Hermes created the lyre for him, and the instrument became a common attribute of Apollo. Hymns sung to Apollo were called paeans.

Apollo Lunar Module

The Apollo Lunar Module (LM), originally designated the Lunar Excursion Module (LEM), was the lander portion of the Apollo spacecraft built for the US Apollo program by Grumman Aircraft to carry a crew of two from lunar orbit to the surface and back. Designed for lunar orbit rendezvous, it consisted of an ascent stage and descent stage, and was ferried to lunar orbit by its companion Command and Service Module (CSM), a separate spacecraft of approximately twice its mass, which also took the astronauts home to Earth. After completing its mission, the LM was discarded. It was capable of operation only in outer space; structurally and aerodynamically it was incapable of flight through the Earth's atmosphere. The Lunar Module was the first, and to date only, manned spacecraft to operate exclusively in the airless vacuum of space.

Six such craft successfully landed on the Moon between 1969 and 1972. A seventh provided propulsion and life support for the crew of Apollo 13 when their CSM was disabled by an oxygen tank explosion en route to the Moon.

Eugene Cernan

Eugene Andrew "Gene" Cernan (/ˈsər.nən/; born March 14, 1934), (CAPT, USN, Ret.), is a retired American naval officer and Naval Aviator, electrical engineer, aeronautical engineer, fighter pilot, and NASA astronaut. He launched into space three times: as Pilot of Gemini 9A in June 1966, as Lunar Module Pilot of Apollo 10 in May 1969, and as Commander of Apollo 17 in December 1972, the final Apollo lunar landing.

On Apollo 17, Cernan became the eleventh person to walk on the Moon and the last man on the Moon since he was the last to re-enter the Lunar Module Challenger after the mission's third and final extravehicular activity (EVA). (Crewmate Harrison Schmitt was the last man to arrive on the Moon, as Cernan left the module first.) Cernan was also a backup crew member for the Gemini 12, Apollo 7 and Apollo 14 space missions.

Biography

Early years

Born on March 14, 1934, in Chicago, Illinois, son of a Slovak father and a Czech mother, Cernan grew up in the suburban towns of Bellwood and Maywood. Graduating from Proviso East High School in Maywood, class of 1952, he entered Purdue University, where he became a member of Phi Gamma Delta fraternity. He received a Bachelor of Science degree in Electrical Engineering in 1956, and was commissioned as a U.S. Navy Ensign through the Naval Reserve Officers Training Corps at Purdue. He became a Naval Aviator flying FJ-4 Fury then A-4 Skyhawk jets in the attack role. He received a Master of Science degree in Aeronautical Engineering from the U.S. Naval Postgraduate School in 1963.

Apollo 11

Apollo 11 was the first spaceflight that landed humans on the Moon. Americans Neil Armstrong and Buzz Aldrin landed on July 20, 1969, at 20:18 UTC (46 years ago). Armstrong became the first to step onto the lunar surface six hours later on July 21 at 02:56 UTC. Armstrong spent about two and a half hours outside the spacecraft, and together with Aldrin collected 47.5 pounds (21.5 kg) of lunar material for return to Earth. The third member of the mission, Michael Collins, piloted the command spacecraft alone in lunar orbit until Armstrong and Aldrin returned to it just under a day later for the trip back to Earth.

Launched by a Saturn V rocket from Kennedy Space Center in Merritt Island, Florida, on July 16, Apollo 11 was the fifth manned mission of NASA's Apollo program. The Apollo spacecraft had three parts: a Command Module (CM) with a cabin for the three astronauts, and the only part that landed back on Earth; a Service Module (SM), which supported the Command Module with propulsion, electrical power, oxygen, and water; and a Lunar Module (LM) for landing on the Moon (which itself was composed of two parts). After being sent toward the Moon by the Saturn V's upper stage, the astronauts separated the spacecraft from it and traveled for three days until they entered into lunar orbit. Armstrong and Aldrin then moved into the Lunar Module and landed in the Sea of Tranquility. They stayed a total of about 21½ hours on the lunar surface. After lifting off in the upper part of the Lunar Module and rejoining Collins in the Command Module, they returned to Earth and landed in the Pacific Ocean on July 24.
