Apollo 20 hardware reassigned to Skylab

SkylabNASA formally cancels the planned Apollo 20 mission to the moon’s Copernicus crater in order to begin converting the upper stage of the mission’s Saturn V rocket into the Skylab space station, to be launched in the early 1970s. Construction of the Apollo command/service module and lunar module scheduled to fly this mission was halted before either vehicle was completed. The crew would have consisted of Stu Roosa, Paul Weitz and Jack Lousma; ironically, Weitz was transferred to the first Skylab crew, while Lousma was part of the second Skylab crew. Both later flew on shuttle missions.

Apollo 12: more footprints on the moon

Apollo 12Astronauts Pete Conrad and Alan Bean land on the moon in the Apollo 12 lunar module Intrepid, a mere 600 feet away from the 1967 landing site of the unmanned Surveyor 3 probe. Pieces of Surveyor 3 are gathered for return to Earth to study the effects of prolonged exposure to the lunar environment. Conrad and Bean conduct two moonwalks, each lasting nearly four hours.

This mission is dramatized in the That’s All There Is episode of HBO’s 1998 series From The Earth To The Moon.

Apollo 12

Apollo 12Apollo 12 lifts off, with astronauts Pete Conrad and Alan Bean set to become the next pair of human moonwalkers aboard the lunar module Intrepid, while Dick Gordon observes from orbit in the command/service module Yankee Clipper. The Intrepid crew is also assigned to deploy an instrument package called ALSEP (Apollo Lunar Scientific Experiment Package) which will be left on the surface even after their departure. The mission lasts ten days.

Apollo 11: first manned lunar landing

Apollo 10The Apollo 11 lunar module touches down in the Sea of Tranquility, a flat plain on the moon. Astronaut Neil Armstrong is the first human being to set foot on another body in the solar system, followed by “Buzz” Aldrin; the two spend roughly two and a half hours on the moon and gather nearly 50 pounds of samples of lunar soil and rock. This feat effectively ends the Cold War space race, though both the United States and the Soviet Union continue their lunar efforts: more Apollo missions are still on the schedule, and the Soviet continue trying to mount a successful launch of their giant N1 rocket.

Apollo 11

Apollo 10Apollo 11 lifts off, with astronauts Neil Armstrong, Buzz Aldrin and Michael Collins aboard. This is the first mission scheduled to attempt a landing on the moon, with Armstrong and Aldrin aboard the lunar module while Collins remains in orbit in the command/service module.

This mission is dramatized in the Mare Tranquilitatis episode of HBO’s 1998 series From The Earth To The Moon.

Apollo 10

Apollo 10Apollo 10 lifts off for a dress rehearsal over the moon. Thomas Stafford, Gene Cernan and John Young fly a complete Apollo stack – both the command/service module and the lunar model – to the moon, conducting practice maneuvers in lunar orbit. Over eight days, the Apollo 10 crew does everything but land on the moon. With the mission requirements fulfilled, NASA announces that the next Apollo mission will attempt an actual landing.

This mission is dramatized in the Spider episode of HBO’s 1998 series From The Earth To The Moon.

NASA solicits shuttle, station proposals

Space ShuttleNASA formally asks various major players in the aerospace industry for proposals for what the agency sees as its two major projects for the 1970s: an orbiting space station and a reusable Space Shuttle to make routine flights from Earth to the station – which NASA hopes will be a “50 man space base” – and back again, with supplies, experiments, and new crew members. (Within mere weeks, the hypothetical station’s equally hypothetical crew will be downsized to a dozen.) In the event that the development curve on the Space Shuttle proves to be a long one, NASA says it will keep Apollo and even Gemini spacecraft in service to make flights to the station.

Apollo 9

Apollo 9Apollo 9 lifts off on a ten-day mission to test the first lunar lander, but only in Earth orbit. Jim McDivitt and Rusty Schweickart put the lunar module, nicknamed Spider, through its paces, while David Scott mans the command module Gumdrop. This is the first flight of the completely non-aerodynamic lunar module, and various docking maneuvers and spacewalk scenarios are practiced. The crew returns to Earth in the Apollo command module, while Spider is left in a low orbit which decays two weeks later, allowing it to disintegrate in Earth’s atmosphere.

Live From The Moon

Apollo 8Broadcasting live black & white television pictures from lunar orbit on Christmas Eve, the crew of Apollo 8 delivers one of the most-watched broadcasts of 1968. As the surface of the moon rolls silently outside the windows of their command/service module, the astronauts take turns reading the first chapter of Genesis, dedicating it to “all of you on the good Earth.” After ten orbits of the moon, Apollo 8 fires its engine, putting it on a return trajectory to Earth; it splashes down safely three days later.

This mission is dramatized in the 1968 episode of HBO’s 1998 series From The Earth To The Moon.

Apollo 8

Apollo 8Moved ahead in the schedule due to ongoing difficulties with the construction of the lunar module, Apollo 8 lifts off from Cape Canaveral on a mission that represents NASA’s biggest gamble yet in the race for the moon: on only the second manned Apollo flight, astronauts Frank Borman, Jim Lovell and Bill Anders will go to the moon, orbit it in their command/service module, and return to Earth (the lunar module is still in the late stages of development). Mission planners plot out a free return trajectory – ensuring that without engines, Apollo 8 could loop around behind the moon and swing back toward home.

This mission is dramatized in the 1968 episode of HBO’s 1998 series From The Earth To The Moon.

Apollo 7

Apollo 7After a year of redesign and reorganization, NASA resumes manned flights with Apollo 7, the first of the successful Apollo flights. An 11-day Earth-orbit shakedown cruise for the Apollo command/service module, the mission becomes contentious when the three-man crew – Wally Schirra, Walt Cunningham and Donn Eisele – is loaded down with a jam-packed mission plan. Worse, Schirra comes down with a cold which quickly spreads to his crewmates in the enclosed biosphere of the Apollo command module. The flight’s technical goals are met with flying colors, though the crew’s snippy responses to ground controllers keep them off the crew rotation for future Apollo flights.

This mission is dramatized in the We Have Cleared The Tower episode of HBO’s 1998 series From The Earth To The Moon.

Apollo 4: Saturn V’s first flight

Apollo 4As questions over the safety of the Apollo spacecraft continue to rage, NASA performs the first “all-up” test of the Saturn V rocket with an unmanned launch officially designated Apollo 4. Unsure of what to expect, onlookers and press are stunned by the roar of the five huge F-1 engines; the vibrations cause CBS news anchor Walter Cronkite’s broadcast booth to partially collapse while he’s on the air – over three miles away. The entire vehicle performs flawlessly, propelling the empty (but active) Apollo command/service module to a distance of 10,000 miles before commanding it to return to Earth, simulating the speed and return angle of a vehicle returning from the moon.

Apollo 1

Crew of Apollo 1During a ground test of the Apollo 1 spacecraft, a fire breaks out in the 100% oxygen atmosphere of the Apollo capsule, leaving the crew – Virgil “Gus” Grissom, Ed White and Roger Chaffee – unable to operate or open the hatch. The searing heat burns through their oxygen hoses, suffocating the three astronauts in short order. Months of investigations and accusations follow, leading to changes of management at both NASA and North American Aviation, the aerospace company contracted to build the Apollo command/service module. Extensive redesign of the Apollo vehicle follows, including a switch to a nitrogen/oxygen atmosphere and a complete rethink of the hatch, and manned flights won’t resume until late 1968.

This event is dramatized in the Apollo One episode of HBO’s 1998 series From The Earth To The Moon.

Vehicle Assembly Building open for business

Vehicle Assembly BuildingNASA’s massive Vehicle Assembly Building is completed at the spaceport rapidly taking shape on Cape Canaveral ahead of the Apollo lunar missions. Topped off at a total cost of $117,000,000, the VAB is where Saturn V rockets are assembled for the Apollo moonshots, and the huge, eight-acre building will later transition to the assembly of the Space Shuttle launch system elements and the Space Launch System boosters for the 21st century Orion program.

Project Orion: lunar and Mars missions studied

Project OrionA report prepared by the Future Projects Office of NASA’s Marshall Spaceflight Center and General Atomic, the nuclear power division of General Dynamics, outlines in great detail ways that existing rocket technology (namely the Saturn V, which will not fly until 1967) and theoretical nuclear pulse propulsion technology could be combined to facilitate exploration of the moon and Mars. (Though derived from the Project Orion studies of the late 1950s, the potential nuclear-powered NASA program suggested in this document is not referred to as Orion.) The report, over 174 pages, goes into great detail about crew module design, radiation exposure, ways to mitigate the inevitable ablation of the “pusher plate” at the rear of the vehicle that will absorb a series of nuclear explosions at close range and translate the energy released into forward thrust, and even possible catastrophic launch abort modes, many of which would qualify as at least a small nuclear disaster. Even the health effects on civilian onlookers of a successful launch are considered, from retinal damage caused by viewing high-altitude firings of the nuclear propellant explosions to fallout risks, as well as potential collateral damage to satellites and non-hardened computers resulting from repeated electromagnetic pulses. The mission profiles considered are constrained to lunar missions and missions to Mars. (It’s worth noting that, by the time of this report’s issuance, the Nuclear Test Ban Treaty has been ratified by both the U.S. and the U.S.S.R., making it illegal to put nuclear pulse propulsion into practice.)

The Vehicle Assembly Building

Vehicle Assembly BuildingConstruction commences on NASA’s massive Vehicle Assembly Building (originally named the Vertical Assembly Building), where the giant Saturn V rockets for Apollo lunar missions will be constructed, tested, and then rolled out to the launch pad atop huge mobile crawlers. Covering eight acres of land on Merritt Island, Florida, the building must withstand Florida’s notorious hurricane seasons (and protect any rockets under construction within) as well as the shockwaves of Saturn V rocket launches taking place only three miles away; special ventilation and humidity control systems have to be built as well, as the interior space is so voluminous that the building has its own internal weather! The VAB will later transition to the assembly of the Space Shuttle launch system elements and the Space Launch System boosters for the 21st century Orion program.

Apollo unveiled

ApolloWeeks before an American astronaut first makes it to orbit, NASA unveils the design of the two Apollo spacecraft: a command/service module (large compared to the Mercury capsules Americans have already seen) and a completely un-aerodynamic lunar module whose unique shape, designed solely for landing on the moon, will never need to operate inside an atmosphere. Though further refinements in both designs are still to come, NASA has already decided on the basic shape of its crash lunar exploration program whose goal is to land a man on the moon before 1970.

Saturn I

Saturn IAn unmanned Saturn I rocket is launched, the first practical demonstration of the multiple-engine design which has already been earmarked for future Apollo missions to the moon. Designed by expatriate German rocket engineer Werhner von Braun, the Saturn I is the first iteration of a family of heavy-lift rockets that will include the Saturn IB and the Saturn V; in this configuration, the Saturn I is the first stage of a Saturn V with no second stage.

MIT to design Apollo spacecraft computers

Apollo Guidance & Navigation computerThe first government contract is issued in the Apollo lunar landing program, as MIT lands the contract to develop the guidance and navigation computer at the heart of the Apollo vehicles. For its day, MIT designed one of the most robust computers that early ’60s technology could squeeze into such a small space; modern digital watches are far more powerful than that computer. The same computer system will be installed in both the command module and the lunar module.
