As god of colonization, Apollo gave oracular guidance on colonies, especially during the height of colonization, 750 – 550 BCE.

SSI ICs, such as the ones used in the Apollo guidance computer, usually contained up to a few score transistors.

Post-war government-sponsored research at MIT included SAGE and guidance systems for ballistic missiles and Project Apollo.

In the NASA Apollo space missions to the moon in the 1960s and 1970s, all onboard computations for primary guidance, navigation and control were provided by a small custom processor called " The Apollo Guidance Computer ".

At the project's inception, the Apollo guidance computer was considered the riskiest item in the Apollo project as it employed the then newly developed monolithic integrated circuits to reduce the size and weight.

Later in the 1960s, Sylvania's Electronic Systems Division in Needham, MA developed and manufactured several instruments for the Apollo Lunar Lander and Command Module using electroluminescent display panels manufactured by the Electronic Tube Division of Sylvania at Emporium, PA. Raytheon, Sudbury, MA, manufactured the Apollo guidance computer, which used a Sylvania electroluminescent display panel as part of its display-keyboard interface ( DSKY ).

The launch was the most harrowing of the Apollo program, as a series of lightning strikes just after liftoff temporarily knocked out power and guidance in the command module.

On August 10th of 1961 NASA Awarded MIT a contract for preliminary design study of a guidance and navigation system for Apollo.

( see Apollo on-board guidance, navigation, and control system, Dave Hoag, International Space Hall of Fame Dedication Conference in Alamogordo, N. M., October 1976 ).

For the Apollo and STS ( Shuttle system ) CSDL " designed " the guidance, McDonnell Douglas wrote the requirements and IBM programmed the requirements.

The Laboratory ’ s achievements includes the design and development of the world ’ s most accurate and reliable guidance systems for undersea-launched ballistic missiles as well as the highly precise, ultra-reliable GN & C systems needed to guide the Apollo astronauts to the Moon and back safely to Earth.

This led to the creation of the Apollo Guidance Computer, a one-cubic-foot computer that controlled the navigation and guidance of the Lunar Excursion Module to the Moon on nine launches, six of which landed on the Moon's surface.

A pioneering figure in the aircraft engineering field, he also contributed to the Apollo space program with his knowledge of guidance systems.

The ascent stage contained the crew cabin, instrument panels, overhead hatch / docking port, forward hatch, optical and electronic guidance systems, reaction control system, radar and communications antennas, ascent rocket engine and fuel to return to lunar orbit and rendezvous with the Apollo Command and Service Modules.

* Apollo guidance computer – PGNCS trouble, another case where a spacecraft guidance computer suffered from having a subsystem inappropriately left running

The Apollo Primary Guidance, Navigation and Control System ( PGNCS ) ( pronounced pings ) was a self-contained inertial guidance system that allowed Apollo spacecraft to carry out their missions when communications with Earth were interrupted, either as expected, when the spacecraft were behind the Moon, or in case of a communications failure.

Inertial guidance systems are not perfect and Apollo system drifted about one milliradian per hour.

REFSMMAT is a term used by guidance, navigation, and control system flight controllers during the Apollo program, which carried over into the Shuttle Program.

During an Apollo flight, the REFSMMAT being used, and therefore the orientation of the guidance platform, would change as operational needs required it, but never during a guidance process — that is, one REFSMMAT might be in use from launch through Trans-Lunar Injection, another from TLI to Midpoint, but would not change during the middle of a burn or set of maneuvers.

During the same period, Unix computer workstations from vendors such as Sun Microsystems, Hewlett-Packard, Silicon Graphics, Intergraph, NeXT and Apollo were using TCP / IP based networking.

* " Colossus ", a computer program developed for NASA's Project Apollo

MISTRAM was a tracking system that was used on a number of projects ( including Project Apollo ) and the Air Force required a data-collection computer to be installed in a tracking station downrange from Cape Canaveral.

The Apollo Guidance Computer with its short production run and stringent reliability requirement was one of the early applications of wire wrap to computer assembly.

It was during a visit by Kalman to the NASA Ames Research Center that he saw the applicability of his ideas to the problem of trajectory estimation for the Apollo program, leading to its incorporation in the Apollo navigation computer.

The Apollo Guidance Computer ( AGC ) was a digital computer produced for the Apollo program that was installed onboard each Apollo Command Module ( CM ) and Lunar Module ( LM ).

The Apollo flight computer was the first to use integrated circuits ( ICs ).

Apollo computer DSKY user interface unit.

The computer used in the spacecraft that first carried humans to the moon, the Apollo Guidance Computer, was constructed entirely using NOR gates with three inputs.

* Apollo Guidance Computer-first deployed computer to exploit integrated circuit technology of on-board, autonomous navigation in space

It was carried as a backup in case of a problem with the Apollo Guidance Computer, although during that mission the computer did not malfunction.

Lunar Lander started as a text-based computer game and went by the names Rocket, Lunar, LEM, and Apollo.

Then he worked as an engineer at Apollo Computer ( later Hewlett-Packard ), and Cahners Publishing as a technical analyst and computer magazine journalist, then for Wang Government Services as a senior Unix systems administrator, before becoming disabled from repetitive strain injury.

Apollo, like other Greek deities, had a number of epithets applied to him, reflecting the variety of roles, duties, and aspects ascribed to the god.

As Artemis's twin, Apollo had the epithet Didymaeus ( ; Διδυμαιος, Didumaios, from δίδυμος, " twin ").

Acesius was the epithet of Apollo worshipped in Elis, where he had a temple in the agora.

As a protector and founder, Apollo had the epithets Alexicacus ( ; Ἀλεξίκακος, Alexikakos, literally " warding off evil "), Apotropaeus ( ; Ἀποτρόπαιος, Apotropaios, from ἀποτρέπειν, " to avert "), and Epicurius ( ; Ἐπικούριος, Epikourios, from ἐπικουρέειν, " to aid "), and Archegetes ( ; Ἀρχηγέτης, Arkhēgetēs, literally " founder "), Clarius ( ; Κλάριος, Klārios, from Doric κλάρος, " allotted lot "), and Genetor ( ; Γενέτωρ, Genetōr, literally " ancestor ").

In his role as god of prophecy and truth, Apollo had the epithets Manticus ( ; Μαντικός, Mantikos, literally " prophetic "), Leschenorius ( ; Λεσχηνόριος, Leskhēnorios, from λεσχήνωρ, " converser "), and Loxias ( ; Λοξίας, Loxias, from λέγειν, " to say ").

As god of music and arts, Apollo had the epithet Musagetes ( ; Doric Μουσαγέτας, Mousāgetās ) or Musegetes ( ; Μουσηγέτης, Mousēgetēs, from Μούσα, " Muse ", and ἡγέτης, " leader ").

Apollo Vindonnus had a temple at Essarois, near Châtillon-sur-Seine in Burgundy.

It was in this way that Apollo had become recognised as the god of music.

Unusually among the Olympic deities, Apollo had two cult sites that had widespread influence: Delos and Delphi.

Apollo had a famous oracle in Delphi, and other notable ones in Clarus and Branchidae.

* In Oropus, north of Athens, the oracle Amphiaraus, was said to be the son of Apollo ; Oropus also had a sacred spring.

Apollo killed Python but had to be punished for it, since Python was a child of Gaia.

Apollo shot arrows infected with the plague into the Greek encampment during the Trojan War in retribution for Agamemnon's insult to Chryses, a priest of Apollo whose daughter Chryseis had been captured.

When Zeus struck down Apollo's son Asclepius with a lightning bolt for resurrecting Hippolytus from the dead ( transgressing Themis by stealing Hades's subjects ), Apollo in revenge killed the Cyclopes, who had fashioned the bolt for Zeus.

Daphne was a nymph, daughter of the river god Peneus, who had scorned Apollo.

By Cyrene, Apollo had a son named Aristaeus, who became the patron god of cattle, fruit trees, hunting, husbandry and bee-keeping.

When he found out the truth he sent his sister, Artemis, to kill Coronis ( in other stories, Apollo himself had killed Coronis ).

Acantha, was the spirit of the acanthus tree, and Apollo had one of his other liaisons with her.

Apollo complained to Maia that her son had stolen his cattle, but Hermes had already replaced himself in the blankets she had wrapped him in, so Maia refused to believe Apollo's claim.

In Aeschylus ' Oresteia trilogy, Clytemnestra kills her husband, King Agamemnon because he had sacrificed their daughter Iphigenia to proceed forward with the Trojan war, and Cassandra, a prophetess of Apollo.
