Walter Marty Schirra Jr. ( shə-RAH; March 12, 1923 – May 3, 2007) was an American naval aviator, test pilot, and NASA astronaut. In 1959, he became one of the original seven astronauts chosen for Project Mercury, which was the United States' first effort to put humans into space. On October 3, 1962, he flew the six-orbit, nine-hour, Mercury-Atlas 8 mission, in a spacecraft he nicknamed Sigma 7, becoming the fifth American and ninth human to travel into space. In December 1965, as part of the two-man Gemini program, he achieved the first space rendezvous, station-keeping his Gemini 6A spacecraft within 1 foot (30 cm) of the sister Gemini 7 spacecraft. In October 1968, he commanded Apollo 7, an 11-day low Earth orbit shakedown test of the three-man Apollo Command/Service Module and the first crewed launch for the Apollo program.
Before becoming an astronaut, Schirra graduated with a Bachelor of Science degree from the United States Naval Academy in 1945, and served at sea during World War II. In 1948, he became a naval aviator, served as a fighter pilot and flew 90 combat missions in the Korean War, and then in 1958 he graduated from the U.S. Naval Test Pilot School. Schirra retired from the Navy in 1969 with the rank of captain.
Schirra was the first astronaut to go into space three times, and the only astronaut to have flown into space in the Mercury, Gemini, and Apollo programs. In total, he logged 295 hours and 15 minutes in space. After Apollo 7, he retired as a captain from the U.S. Navy as well as from NASA, subsequently becoming a consultant to CBS News in the network's coverage of following Apollo flights. Schirra joined Walter Cronkite as co-anchor for all seven of NASA's Moon landing missions.
Schirra was born on March 12, 1923, in Hackensack, New Jersey, to a family of aviators. His paternal grandfather Adam Schirra emigrated with his wife Josephina (Marty) Schirra to the United States from Bavaria. Schirra's father, Walter M. Schirra Sr. (1893–1973), who was born in Philadelphia, joined the Royal Canadian Air Force during World War I, and flew bombing and reconnaissance missions over Germany. After the war, he performed as a barnstormer at county fairs in New Jersey, as did Schirra's mother, Florence Shillito Schirra (née Leach; 1898–1982), who performed wing walking stunts.
Schirra Jr. grew up in Oradell, New Jersey, where he attended elementary school and was a First Class Scout in Boy Scout Troop 36. He graduated from Dwight Morrow High School in Englewood, New Jersey, in June 1940 and enrolled in the Newark College of Engineering (now New Jersey Institute of Technology, NJIT), where he was involved in the Reserve Officer Training Corps (ROTC) and the Sigma Pi fraternity. Following the attack on Pearl Harbor in December 1941, Schirra decided to apply to a service academy. His father encouraged him to apply to West Point, but he decided to enroll in the United States Naval Academy instead. He graduated with a Bachelor of Science degree in 1945 after only three years instead of four, as the Naval Academy had a wartime accelerated curriculum.
After graduating from the Naval Academy, Schirra was commissioned as an ensign in the United States Navy on June 6, 1945. He served during the final months of World War II aboard the large cruiser USS Alaska. Following the Japanese surrender, he returned to the U.S., where the Alaska was decommissioned. He was subsequently stationed to Qingdao and assigned to the amphibious command ship USS Estes. Following his return from China, he began training as a Naval Aviator at Naval Air Station Pensacola, Florida.
After he completed training, Schirra received his naval aviator wings in 1948 and joined Fighter Squadron 71 (VF-71) at Quonset Point, Rhode Island. In VF-71, Schirra flew the F8F Bearcat. After several years of flying the F8F, he attended jet transition training with the F-80 Shooting Star in preparation for his squadron's transition to the jet-powered F9F Panther. Schirra was deployed to the Mediterranean aboard the aircraft carrier USS Midway at the outbreak of the Korean War in June 1950. He applied for an exchange program with the U.S. Air Force to gain combat experience, was selected for the program, and trained to fly on the F-84 Thunderjet.
Schirra was initially deployed with the 154th Fighter-Bomber Squadron to Itazuke Air Force Base in Japan, from where he flew missions into South Korea. As U.S. troops advanced north, the squadron was reassigned to a base in Daegu. In the eight-month deployment, Schirra flew 90 combat missions and downed two MiG-15s.
After completing his tour in Korea, Schirra became a test pilot at Naval Ordnance Test Station China Lake, California (NOTS). At China Lake, he tested various weapons systems, including becoming the first pilot to fly with and fire the Sidewinder missile. He was assigned to Miramar Naval Air Station to test the newest Navy jet fighter, the F7U Cutlass. He was subsequently assigned to NAS Moffett to begin transition training to the Cutlass, and subsequently the F3H Demon. After a deployment to Asia aboard the aircraft carrier USS Lexington and aviation safety training with the University of Southern California (USC), he was accepted to the U.S. Naval Test Pilot School in 1958.
Schirra was a member of Class 20 at the Naval Test Pilot School, along with future fellow astronauts Jim Lovell and Pete Conrad, where he learned to fly numerous aircraft, including the F4D Skyray, the F11F Tiger, and the F8U Crusader. After graduation, Schirra became a test pilot at Naval Air Station Patuxent River and learned to fly the F4H Phantom to determine if it could become a carrier-based aircraft.
In February 1959, Schirra was one of 110 military test pilots selected by their commanding officers as candidates for the newly formed National Aeronautics and Space Administration's Project Mercury, the first U.S. crewed space flight program. Following several rounds of tests, Schirra became a member of the original seven astronauts selected for the program in April 1959.
During the program's development, Schirra's areas of responsibility were the life-support systems and the pressurized flight suit. Additionally, Schirra worked alongside John Glenn in capsule design. Scott Carpenter and Schirra flew F-106 Delta Dart chase planes during Alan Shepard's Freedom 7 suborbital mission. Schirra was initially assigned as Deke Slayton's backup for the second orbital Mercury flight but was replaced with Carpenter when Slayton was grounded. Schirra was instead scheduled for the third orbital flight.
At 7:15 am on October 3, 1962, Schirra lifted off aboard his Mercury flight, named Sigma 7. After a minor trajectory deviation early in flight, Sigma 7 achieved orbit. Once in orbit, Schirra demonstrated manually positioning and maneuvering his spacecraft using a reaction control system. After the navigation issues during Carpenter's Aurora 7 mission, NASA and Schirra focused on the engineering and human factors in manually operating the capsule. Schirra reported rising suit temperatures, reaching a high of 32 °C (90 °F), before he was able to adjust his suit's cooling system manually. After completing his spacecraft tests, Schirra tested his ability to use controls in a zero-gravity environment without sight. Throughout his mission, Schirra demonstrated the ability to act as a backup to automatic controls and manually fly the spacecraft.
After six orbits, Schirra manually aligned his spacecraft over Africa and performed retrofire. Sigma 7 landed 5 miles (8.0 km) from the recovery ship, the aircraft carrier USS Kearsarge, in the central Pacific Ocean. Once Sigma 7 was on deck, Schirra activated the explosive hatch to egress the spacecraft, and received a large bruise, proving that Grissom had not intentionally opened his hatch on Liberty Bell 7. After Schirra returned to the US, he and his family were invited to the Oval Office at the White House to meet President Kennedy on October 16.
At the beginning of the Gemini program, Alan Shepard was assigned to command Gemini 3 with Tom Stafford as the pilot, but they were replaced by a backup crew after Shepard was diagnosed with Ménière's disease, a disorder of the inner ear. Schirra and Stafford became the backup crew for the new Gemini 3 crew, Gus Grissom and John Young, and were subsequently scheduled for the Gemini 6 primary crew. Gemini 6 was originally scheduled to perform the first orbital docking with an Agena target vehicle. The Agena vehicle exploded during its launch into orbit on October 25, 1965, while Schirra and Stafford waited in their spacecraft to lift off. Program managers decided that rather than wait for a replacement Agena to be available, they would revise the mission, calling it Gemini 6A and having it attempt a rendezvous with Gemini 7, to be flown by Frank Borman and Jim Lovell. On December 4, 1965, Gemini 7 lifted off to begin its two-week mission.
