Short answers, pulled from the story.
Apollo 7 was the first crewed flight of NASA's Apollo program, launching on the 11th of October, 1968, and splashing down on the 22nd of October, 1968. Its primary purpose was to test the redesigned Apollo command and service module in low Earth orbit following the Apollo 1 fire that killed three astronauts in January 1967.
Apollo 7 was commanded by Walter M. Schirra, with Donn F. Eisele as Command Module Pilot and R. Walter Cunningham as Lunar Module Pilot. Schirra, at 45, was the only astronaut to fly in all three programs: Mercury, Gemini, and Apollo.
The Apollo 7 crew's repeated conflicts with Mission Control during the flight damaged their standing with NASA leadership. Director of Flight Operations Christopher C. Kraft reportedly told Deke Slayton he was unwilling to work with any crew member in the future. Schirra had already announced his retirement before the mission; Eisele left the Astronaut Office in 1970, and Cunningham resigned in 1971.
Apollo 7 carried out the first live television broadcast from an American spacecraft, beginning on the 14th of October, 1968. The seven-minute broadcast opened with a card reading "From the Lovely Apollo Room high atop everything." The crew later received a special Emmy Award for their daily telecasts.
More than 1,800 changes to the Apollo command and service module were recommended following the Apollo 1 fire; 1,300 of those changes were implemented before Apollo 7 flew. Key changes included a new outward-opening hatch, replacement of flammable materials, and a revised atmospheric mix at launch.
The Apollo 7 command module is on loan to the Frontiers of Flight Museum at Love Field in Dallas, Texas. After the mission, it was displayed in the inauguration parade of President Richard M. Nixon in January 1969, then transferred to the Smithsonian Institution in 1970, before being loaned to the National Museum of Science and Technology in Ottawa, Ontario, and returned to the United States in 2004.
