Apollo Program: Tragedy and Triumph (All Parts)
Epic History・2 minutes read
Yuri Gagarin and Alan Shepherd were the first humans in space during the Cold War, leading to President Kennedy's goal of landing a man on the Moon. The Apollo program faced challenges, tragedies, and triumphs, with Apollo 11 successfully landing on the Moon in 1969.
Insights
- John Houbolt proposed a strategy of sending two spacecraft to the Moon, a command module, and a lunar excursion module, to reduce weight and launch on a smaller rocket, showcasing innovative design thinking within NASA.
- Apollo 13 faced a life-threatening disaster due to an accidental fire in an oxygen tank, leading to the crew's survival depending on the Lunar Module as a lifeboat and NASA's ingenuity in developing makeshift solutions for critical issues, highlighting the resilience and resourcefulness of both the astronauts and ground control.

Race to Moon: Apollo Program's Journey
- In 1961, during the Cold War, Yuri Gagarin and Alan Shepherd became the first man in space for the Soviet Union and the United States, respectively.
- President Kennedy proposed landing a man on the Moon before the end of the decade to surpass the Soviet space program.
- NASA faced the challenge of designing a spacecraft for a lunar mission, with Werner Von Braun suggesting launching it in pieces and assembling it in orbit.
- John Houbolt proposed sending two spacecraft to the Moon - a command module and a lunar excursion module - to reduce weight and launch on a smaller rocket.
- The Apollo 1 crew tragically died in a fire during a ground test due to faulty wiring and the spacecraft's design flaws.
- Apollo 7, following redesigns for safety, successfully tested the new Apollo spacecraft, setting the program back on track.
- Apollo 8, originally intended for a lunar module test, orbited the Moon with Frank Borman, Jim Lovell, and Bill Anders, capturing the iconic Earthrise photo.
- The success of Apollo 8 brought hope for achieving Kennedy's goal of landing on the Moon by the end of the decade.
- Apollo 9, led by Jim McDivitt, tested the Lunar Module in Earth orbit, facing challenges like docking maneuvers and the spacecraft's unique design.
- The Lunar Module, nicknamed 'Spider,' was a crucial part of the Apollo Program, designed for space travel without a heat shield for Earth re-entry.

Apollo Missions: Moon Landings and Challenges
- Spider’s test flight was successful, with McDivitt and Schweickart flying the Lunar Module over 100 miles from the Command Module, testing engines and returning safely.
- NASA had tested both the Command Module and Lunar Module successfully, preparing for a moon flight.
- Challenges faced by NASA included communication and tracking of two spacecraft in lunar orbit, rendezvous, docking, and the Moon's uneven gravitational field due to mascons.
- Apollo 10, a dress rehearsal for the moon landing, was flown by Commander Tom Stafford, Command Module Pilot John Young, and Lunar Module Pilot Gene Cernan.
- Apollo 11 was commanded by Neil Armstrong, with Buzz Aldrin as Lunar Module Pilot and Michael Collins as Command Module Pilot.
- Armstrong's calm under pressure was proven during Gemini 8, and Aldrin's expertise in orbital mechanics was showcased during Gemini 12.
- The launch of Apollo 11 on July 15, 1969, was met with protests led by Reverend Ralph Abernathy, highlighting issues of poverty.
- Despite protests, Apollo 11 launched successfully, with Armstrong and Aldrin landing on the moon on July 20, 1969.
- Apollo 12 aimed for a pinpoint landing next to the Surveyor 3 probe, with Mission Commander Pete Conrad, Command Module Pilot Dick Gordon, and Lunar Module Pilot Alan Bean.
- Apollo 13, focusing on scientific discovery, faced a disaster with Mission Commander Jim Lovell, Lunar Module Pilot Fred Haise, and Command Module Pilot Ken Mattingly (later replaced by Jack Swigert) fighting for survival.

Apollo 13: Survival and Success in Space
- Apollo 13 crew completes live TV broadcast on the way to the Moon, but no US TV network carries the show due to fading public interest in the Apollo Program.
- Crew instructed to stir cryo tanks to address uneven oxygen distribution issue caused by zero gravity in the command and service module.
- Accidental heater left on in oxygen tank number two during ground test leads to a fire when the fan is turned on, turning the tank into a bomb.
- Second oxygen tank damaged in the blast, leading to oxygen loss and the crew's survival relying on the lunar module, Aquarius, as a lifeboat.
- NASA develops makeshift air purifier using a lithium hydroxide canister, cardboard, tape, and an astronaut's sock to filter carbon dioxide in the Lunar Module.
- Apollo 13 crew survives re-entry into Earth's atmosphere after facing numerous engineering and navigation challenges.
- Apollo 14 sees Alan Shepard return to space after undergoing experimental surgery for Ménière's disease, overcoming glitches to make a successful landing on the Moon.
- Apollo 17, the final Apollo mission, lands at Taurus-Littrow with Gene Cernan and Harrison Schmitt, collecting extensive scientific data before leaving the Moon.
