Appolo 1

Apollo 1 is the official name that was later given to the never-flown Apollo/Saturn 204 (AS-204) mission.

 It's command module (CM-012) was destroyed by fire during a test and training exercise on January 27, 1967 at Pad 34 (Launch Complex 34, Cape Canaveral, then known as Cape Kennedy) atop a Saturn IB rocket. 

The crew aboard were the astronauts selected for the first manned Apollo program mission: Command PilotVirgil I. "Gus" Grissom, Senior Pilot Ed White and Pilot Roger B. Chaffee. All three died in the fire.

Even though the ignition source of the fire was never conclusively identified, the astronauts' deaths were attributed to a wide range of lethal design hazards in the early Apollo command module. 

Among these were the use of a high-pressure 100 percent-oxygen atmosphere for the test, wiring and plumbing flaws, flammable materials in the cockpit (such as Velcro), an inward-opening hatch that would not open in this kind of an emergency and the flight suits worn by the astronauts

A seven-member board conducted a comprehensive investigation to pinpoint the cause of the fire and  

the final report  was  submitted to the NASA Administrator. 

The report presented the results of the investigation and made specific recommendations that led to major design and engineering modifications, and revisions to test planning, test discipline, manufacturing processes and procedures, and quality control. 

With these changes, the overall safety of the command and service module and the lunar module was increased substantially. The AS-204 mission was redesignated Apollo I in honor of the crew.

AS-204 was to be the first manned flight of a command and service module (CSM) to Earth orbit, launched on a Saturn 1B. CM-012, the Apollo 1 command module, was a Block I design built for spaceflight but never intended for a trip to the moon since it lacked the needed docking equipment.

The AS-204 mission was scheduled for the first quarter of 1967, having already missed a target date for the last quarter of 1966. The flight was to test "launch operations, ground tracking and control facilities and the performance of the Apollo-Saturn launch assembly" and would have lasted up to two weeks, depending on how the spacecraft performed.

The Appolo Program

The Apollo Program was a human spaceflight program undertaken by NASA during the years 1961–1975 with the goal of conducting manned moon landing missions. 

In 1961, President John F. Kennedy announced a goal of landing a man on the moon by the end of the decade. It was accomplished on July 20, 1969 by the landing of astronauts Neil Armstrong and Buzz Aldrin, with Michael Collins orbiting above during the Apollo 11 mission.

 Five other Apollo missions also landed astronauts on the Moon, the last one in 1972. These six Apollo spaceflights are the only times humans have landed on another celestial body.The Apollo program, specifically the lunar landings, is often cited as the greatest achievement in human history.

Apollo was the third human spaceflight program undertaken by NASA, the space agency of the United States. It used Apollo spacecraft and Saturn launch vehicles, which were later used for the Skylab program and the joint American-Soviet Apollo-Soyuz Test Project. These later programs are thus often considered to be part of the overall Apollo program.

The Apollo program included a large number of uncrewed test missions and 11 crewed missions. The 11 crewed missions include two Earth orbiting missions, two lunar orbiting missions, a lunar swingby and six Moon landing missions.

The Apollo program was designed to land humans on the Moon and bring them safely back to Earth. Six of the missions -- Apollos 11, 12, 14, 15, 16 and 17 -- achieved this goal. Lunar surface experiments included soil mechanics, meteoroids, seismic, heat flow, lunar ranging, magnetic fields and solar wind experiments

Apollo 8 was the first manned spacecraft to orbit another celestial body.

Apollos 7, which tested the Command Module, and 9, which tested both the Command Module and Lunar Module, were Earth orbiting missions. Apollos 8 and 10 tested various components while orbiting the Moon, and returned photography of the lunar surface. Apollo 13 did not land on the lunar surface due to a malfunction, but during the brief orbit around the Moon, the crew was able to collect photographs.

The goal of the program, as articulated by President Kennedy, was accomplished with only two major failures.

 The first failure resulted in the deaths of three astronauts, Gus Grissom, Ed White and Roger Chaffee, in the Apollo 1 launchpad fire. 

The second was an in-space explosion on Apollo 13, which badly damaged the spacecraft on the moonward leg of its journey. The three astronauts aboard narrowly escaped with their lives, thanks to the efforts of flight controllers, project engineers, backup crew members and the skills of the astronauts themselves.Apollo 17 marks the time of the last moonwalk and also the last manned mission beyond low Earth orbit.

After the last lunar landing, total funding for the Apollo program was about $19,408,134,000. The budget allocation was 34 percent of the NASA budget.

The program set major milestones in the history of human spaceflight. This program stands alone in sending manned missions beyond low Earth orbit.
