1962 talks led to the Dryden-Blagonravov agreement, which was formalized in October of that year, the same time the two countries were in the midst of the Cuban Missile Crisis. The agreement was formally announced at the United Nations on 5 December 1962. It called for cooperation on the exchange of data from weather satellites, a study of the Earth's magnetic field, and joint tracking of the NASA Echo II balloon satellite. Kennedy could even interest Khrushchev in a joint crewed Moon landing. The assassination of Kennedy on 22 November 1963, and the removal from office of Khrushchev on 14 October 1964, made any personal preferences of the respective leaders moot. Unfortunately, as the competition between the two nation's crewed space programs heated up, efforts to further cooperation at that point came to an end. Due to tense relations and military implications, space cooperation between the United States and the Soviet Union was unlikely in the early 1970s. On 7 June 1971, the USSR had launched the first piloted orbital space station, Salyut 1. Meanwhile, the United States had launched the Apollo 14 mission several months prior, the third space mission to land humans on the Moon. Each side gave the other little coverage of their achievements. Both sides had severe criticisms of the other side's engineering. Soviet spacecraft were designed with automation in mind; the Lunokhod 1 and Luna 16 were both uncrewed probes, and each Soyuz spacecraft had been designed to minimize risk due to human error by having fewer manual controls with which human operators would have to contend during flight. By contrast, the Apollo spacecraft was designed to be operated by humans and required highly trained astronauts in order to operate. The Soviet Union criticized the Apollo spacecraft as being "extremely complex and dangerous". The Americans also had their own concerns about Soviet spacecraft. Christopher C. Kraft, director of the Johnson Space Center, criticized the design of the Soyuz: "We in NASA rely on redundant components — if an instrument fails during flight, our crews switch to another in an attempt to continue the mission. Each Soyuz component, however, is designed for a specific function; if one fails, the cosmonauts land as soon as possible. The Apollo vehicle also relied on astronaut piloting to a much greater extent than did the Soyuz machine." The American astronauts had a very low opinion for the Soyuz space craft
