Apollo 7 slow-scan TV, transmitted by the RCA command module TV camera. NASA decided on initial specifications for TV on the Apollo command module (CM) in 1962. [2] [ Note 1] Both analog and digital transmission techniques were studied, but the early digital systems still used more bandwidth than an analog approach: 20 MHz for the digital system, compared to 500 kHz for the analog system.

The Apollo 12 empty S-IVB, Instrument Unit, and spacecraft adapter base, had a mass of about 14 tonnes; 15 short tons (30,000 lb). [6] This is less than one-fifth of the 77.1-tonne; 85.0-short-ton (169,900 lb) mass of the Skylab space station , which was constructed from a similar S-IVB and fell out of orbit on 11 July 1979.

His final space mission was in 1975 on the Apollo-Soyuz Test Project, which was the first international space mission and demonstrated the first ever docking of American and Soviet spacecraft ...
In 1969, he commanded Apollo 10, the second crewed mission to orbit the Moon. Here, he and Gene Cernan became the first to fly an Apollo Lunar Module in lunar orbit, descending to an altitude of nine miles (fourteen kilometres). In 1975, Stafford was the commander of the Apollo-Soyuz Test Project (ASTP) flight, the first joint U.S.-Soviet space ...
The Soviet Union built five Soyuz spacecraft that used APAS-75. The first three flew as test systems (Cosmos 638, Cosmos 672 and Soyuz 16). The fourth one was used for the Apollo-Soyuz Test Project, Soyuz 19 the only Soyuz to actually use the docking system, while the last APAS-75 fitted to Soyuz 22 was replaced by a camera prior to flight [8 ...
The US conducted the first crewed spaceflight to leave Earth orbit and orbit the Moon on December 21, 1968, with the Apollo 8 space mission. Later they succeeded in achieving President Kennedy's goal on July 20, 1969, with the landing of Apollo 11 .
