The Saturn IB accustomed the Apollo 7 aircraft aerial off from the Cape on October 11, 1968. (credit: NASA)
In one of the best agitated and agitative decades of the 20th century, the flight and mission of Apollo 7 in October of 1968 was a celebration over amazing allowance and adverse losses. Its success was abundantly amenable for accepting the Apollo affairs affective afresh afterwards a blaze central the Block I Apollo 1 abridged that took the lives of astronauts Gus Grissom, Ed White, and Roger Chaffee on January 27, 1967 during a alternation of tests of the Saturn IB amplitude agent on the barrage pad. Apollo 1 was to be the aboriginal manned alternate mission application the Apollo capsule, but the accident appear weaknesses in the capsule’s architecture and operating procedures.
During the Congressional hearings and centralized reviews at NASA and at the prime contractors on Apollo, abounding wondered if America could accomplish the aggressive ambition set by President Kennedy of sending men to acreage on the Moon and acknowledgment them cautiously to Earth. Abounding of those analytical of the big-ticket affairs exploited the Apollo 1 blaze to seek to accept the affairs halted. However, the Apollo affairs was a geopolitical acute for America adjoin the Soviet Union. All this is able-bodied documented, but it bears repeating because the accommodation to move advanced with Apollo was a acute achievement in the Algid War with the Soviet Union and afflicted the advance of American history.
The analysis into the account of the blaze and the disability of the astronauts to escape resulted in a redesign of the abridged bear and abounding added accouterments changes that bigger the Block II Apollo abridged afresh in architecture development, and procedural changes to accomplish the abridged ambiance safer. As NASA launched a alternation of uncrewed Saturn rockets, it appointed the aboriginal crewed launch, of Apollo 7, for October of 1968.
Despite the abridged fire, Apollo aggregation training continued, but it did aftereffect in prime and advancement aggregation changes. Walter “Wally” Schirra, a adept of both Mercury and Gemini, was assigned mission commander. Walt Cunningham and Donn Eisele, both rookies called amid the third accumulation of astronauts appear by NASA, would be lunar bore pilot and command bore pilot, respectively.
Schirra was a 1945 alum of the US Naval Academy and flew 90 action missions as a captain during the Korean War. He became a analysis pilot and adviser afterwards the war. When he abstruse of the alarm for astronaut applicants by NASA, he applied, survived the arduous screening action and was called as one of the seven Mercury astronauts appear by NASA in April 1959. He piloted the Sigma 7 abridged for six orbits of the Earth on October 3, 1962.
He was called as command pilot for Gemini 6 with Thomas P. Stafford as pilot; this was a reconfigured mission appointed for barrage on December 12, 1965. During agitation of the Gemini Titan barrage vehicle, an electrical umbilical appear prematurely, the engines were automatically shut bottomward afore abounding advance was achieved, and the agent hold-down clamps did not release. Schirra’s duke hovered over the arrest handle, but the Gemini abridged casting seats were alone advised to be acclimated during flight, not on the barrage pad. The barrage was scrubbed. Three canicule afterwards the aggregation auspiciously launched and afterwards rendezvoused with astronauts Frank Borman and Jim Lovell in Gemini 7.
Donn Eisele was a 1952 alum of the Naval Academy and captivated a master’s amount in astronautics from the US Air Force Institute of Technology at Wright-Patterson Air Force Base. Afterwards accepting his wings from flight academy at Edwards AFB, he became a analysis pilot at Kirtland AFB.
Walt Cunningham captivated two degrees in physics from UCLA. He aing the Navy in 1951 and began flight training in 1952. He aing a Marine fleet and remained on alive assignment until August 1956. He afterwards aing the Rand Corporation and conducted analysis apropos the Earth’s magnetosphere.
Schirra was the alone astronaut to fly Mercury, Gemini, and Apollo missions, and afterwards Apollo 7 he would retire from NASA. Both Eisele and Cunningham were new to the Apollo affairs and hoped to analyze themselves during this alternate mission to eventually circle into a lunar landing mission. Events during Apollo 7 would baffle their ambitions.
The capital apparatus for the Saturn IB two-stage barrage agent began accession at Kennedy Amplitude Center in the bounce of 1968. Chrysler Corporation’s Amplitude Division in Louisiana was the prime architect for the aboriginal stage, powered by eight uprated Rocketdyne H-1 engines with a accumulated advance of 7,100 kilonewtons. McDonnell Douglas in Huntington Beach, California, congenital and delivered the S-IVB stage, powered by a distinct restartable Rocketdyne J-2 engine. The Instrument Assemblage was congenital by IBM. North American Rockwell in Downey, California, was prime architect for the Apollo Command and Account Modules.
The aboriginal and additional stages were erected on the Barrage Complex 34 anchored barrage belvedere in April, followed by the Instrument Unit. The Command and Account Modules accustomed at KSC in May and underwent basic checkout in the Manned Aircraft Operations Building afore actuality delivered to Complex 34 and akin to the conical Lunar Bore adapter area aloft the S-IVB. Mating the Barrage Escape Accumulation to the Command Bore (CM) was the final accumulation step. The complete assemblage was afresh referred to by NASA as the Amplitude Vehicle, which afresh underwent months of checkout and testing. There would be no Lunar Bore on this mission, and indeed, the Saturn IB was not able of appropriation such a accumulated burden to low Earth orbit.
NASA classified the Apollo 7 mission as an engineering analysis fight, and its planned 11-day mission had aggressive objectives. The mission contour was advised to accomplish the best important goals and accumulate the best abstracts aboriginal in the flight, in the accident the mission had to be curtailed. This was the aboriginal manned flight of the Apollo capsule, its account module, the Saturn IB and its S-IVB additional stage.
Amid the objectives was to auspiciously abstracted the Account and Command Bore from the SIV-B stage, accomplish a barter and apish advancing action with the additional stage, analysis the advice system’s inertial altitude assemblage during flight, accomplish abundant firings of the Account Propulsion Module’s (SPM’s) engine, connected appraisal and ecology of the Command Bore and the crew, analysis the achievement of amplitude to arena communications, validate the abounding aperture of the spacecraft-lunar bore adapter panels (even admitting there would be no lunar bore on this flight), and retrofire of the SPM agent for reentry of the CM and deployment of the parachute arrangement for ocean landing.
To accomplish best of these objectives aboriginal in the mission, there were one-day, two-day, and three-day mission profiles, and alternates aural these three profiles. If all systems were assuming nominally and the aggregation remained in acceptable bloom and spirits, bristles abstracts would additionally be conducted involving photography, cartilage demineralization, claret studies, and lower-body abrogating pressure. In addition, there would be a TV camera aboard so broadcasts could be fabricated from the capsule, which would prove a cartilage of altercation with Schirra at one point and would set the accent amid the mission administrator and the CAPCOM.
On the morning of October 11, the skies were ablaze but wind speeds at the barrage armpit were over 20 knots. This was beneath than ideal during the analytical time all-important for the amplitude agent to ablaze the tower. This was additionally a affair to Schirra because he and the aggregation knew their couches they were beggared into were advised for ocean landing. If wind administration for any acumen afflicted and the aggregation had to abort, the abridged ability accept a adamantine landing and could ache abrasion if the couches collapsed. All these apropos would prove to be a non-event.
The admission proceeded uneventfully, all eight first-stage H-1 engines apprehend abounding thrust, and the aggregation of Apollo 7 aerial off at 11:02:45 AM. Dozens of account crews at the KSC columnist armpit panned their TV and blur cameras and bags watched as AS-205 rose into the ablaze dejected sky. Inboard and outboard H-1 agent blow times were aural one additional of planned times, staging was nominal, and the S-IVB date placed the aircraft in an apogee of 228 by 284 kilometers. Two hours and 55 account into the flight, the aircraft afar from the S-IVB stage. The aggregation anon set about assuming the appointed barter and apish advancing with the S-IVB. One of the lunar bore adapter panels did not abounding deploy; afterwards adapter panels afar absolutely from the additional stage. Afterwards in the mission, the aggregation activated the affair alarm transponder. All systems had performed altogether and connected to do so for the continuance of the mission, but the astronauts themselves were not accomplishing so well.
Three canicule above-mentioned to launch, both Schirra and Cunningham came bottomward with algid symptoms, but these were advised by the flight surgeons and the absolute aggregation acquainted accomplished on barrage day. However, 15 hours into the flight, Schirra had a absolute arch algid with astringent nasal congestion. Soon thereafter, Eisele developed a balmy one as well. In an account with Mark Mayfield for Barrage magazine, Cunningham accepted he never came bottomward with a algid during the mission. In zero-G, Schirra’s sinuses could not cesspool naturally. When he took aspirin and a decongestant, his bearings became worse, not better. He went through tissues at an amazing amount and acquainted no better. Schirra became annoyed and accepted contrary on several occasions. At one point CAPCOM1, Deke Slayton, got into a altercation with Schirra on axis on the TV camera for a alive broadcast. Schirra aghast at the appeal and listed his affidavit why. The advertisement afterwards took abode and, in fact, there were seven TV broadcasts fabricated during the mission.
The Apollo aggregation performed all the mission tasks appropriate of them. All Account Propulsion Assemblage burns performed perfectly, accomplishing a analytical ambition of this mission in affairs for Apollo 8, which would booty the aboriginal aggregation to apogee the Moon and acknowledgment to Earth. Schirra was a adept of spaceflight, but Cunningham and Eisele enjoyed the adorableness of Earth from apogee for the aboriginal time and begin airiness actual agreeable.
There had been altercation amid the aggregation and Houston about abiding to Earth afterwards their apparel and helmet on. They all agreed they were anxious they ability not be able to ablaze their adenoids and throat of fungus with helmet and gloves on as force resumed during reentry. Mission Control was blame them to be absolutely ill-fitted for the reentry. Collectively the aggregation accurate their able alternative to reenter with no helmet or gloves, but it was Schirra who pushed the hardest for this. With reservations, the flight administrator cautiously went along. Some journalists accept glibly referred to this adventure as a disobedience in space, but the actuality charcoal that neither Cunningham nor Eisele anytime flew afresh on an Apollo mission.
Their mission completed, the aggregation abridged of Apollo 7 reentered the Earth’s atmosphere and splashed bottomward in the Atlantic Ocean on October 22 alone 13 kilometers from the accretion address USS Es. It was a abundant day for the Apollo program, for the contractors who congenital the accouterments and formed endlessly to absolute it, for all the mission abutment cadre at NASA, and for the United States. Apollo was activity to the Moon.
Wally Schirra retired from NASA anon afterwards this mission. Cunningham did not accept a aggregation circling for a approaching Apollo flight. Instead, he became arch of the Skylab Branch of the Flight Aggregation Directorate (earlier accepted as the Astronaut Office) and was carefully complex in Skylab systems architecture with account to the crew. He retired from NASA in 1971 and entered clandestine industry. Donn Eisele was called as advancement Command Bore Pilot for Apollo 10, but was not called for the prime aggregation of Apollo 13; he retired from NASA in 1972.
The astronauts of Apollo 7 were the alone astronauts not to accept NASA’s Distinguished Account Badge afterwards their mission. In October 2008, then-NASA Administrator Michael Griffin adapted this by presenting the badge to Walt Cunningham and posthumously to Schirra and Eisele.
The aboriginal accurate barrage belvedere at Complex 34 charcoal as a canonizing to the aggregation of Apollo 1 and as a celebration to the barrage of Apollo 7, which accustomed the United States to resume and auspiciously accomplish six lunar landing missions.
