As an alternative, Low suggested that MSC should cooperate with the Air Force to maximize gains from the USAF task on space rescue requirements.

1966 May 11 - . LV Family: N1. Launch Vehicle: N1.
  • Mishin selected as Korolev's replacement after four-month delay - . Nation: USSR. Related Persons: Korolev; Ustinov; Mishin; Okhapkin; Keldysh; Babakin; Mozzhorin; Khrushchev. Program: Lunar L3; Lunar L1. Flight: Soyuz 1; Soyuz 2A. Spacecraft: LK; Soyuz 7K-LOK. From 1963-1965 Ustinov was both head of the Soviet for the National Economy and the First Secretary of the Presidium of Soviet Ministers. He supported civilian space projects and instructed the military to co-operate in them. But after Khrushchev was ousted, Ustinov had less influence with the Ministry of Defence.

    After the death of Korolev in January, a letter was sent to the Central Committee requesting that Mishin be appointed director of OKB-1. Ustinov tried to line up support for Mishin, but by the time of the first first Saturn IB orbital flight on 26 February 1966, no decision had been made. America was progressing on the path to the moon, but Russia was stalled. An alternate that had been considered was Sergei Okhapkin, another Deputy Chief Designer at TsKBEM. But Okhapkin knew only spacecraft, he had never developed complete launch-booster-spacecraft systems. By the time Mishin was appointed, it was clear that the race was lost. The American's planned their first Saturn V launch in September 1967 and their first manned flight in 1968. Mishin could not expect trials of the LK lunar lander until 1969 at the earliest. There were insufficient funds allocated, and the schedule had no allowance for test flight failures. Ustinov, Morozhin, and Keldysh pointed fingers as to who had presented such unrealistic schedules to the Politburo. Keldysh now supported unmanned robot lunar landers in development by Babakin. Even these would not land until 1970, allowing three years of flight trials to achieve reliability. Khrushchev, it seemed, was to blame for such enormous unaffordable projects. This in turn put Ustinov in danger, as Khrushchev's point man for space.


1966 May 11 - .
  • Refurbished CSMs proposed for AAP. - . Nation: USA. Related Persons: Gilruth; Mueller. Spacecraft: Apollo CSM; Apollo LM Lab; Apollo X. Replying to a suggestion by MSC Director Robert R. Gilruth that AAP capitalize on Apollo hardware to an even greater extent by using refurbished CSMs, Associate Administrator for Manned Space Flight George E. Mueller deferred any action toward implementing a competitive effort for such work. This was necessary, he said, because of the present unsettled nature of AAP planning. Additional Details: Refurbished CSMs proposed for AAP..

  • Cosmonaut jet trainers. - . Nation: USSR. Related Persons: Titov; Nikolayev; Leonov; Belyayev; Bykovsky; Popovich; Kuznetsov, Nikolai Fedorovich. Holidays - in the first ten days of May, the civilians work only two days, while the military must work four. Kamanin assigns cosmonauts to the State Commission that will select the design for the Gagarin memorial obelisk. He then reviews cosmonaut pilot aircraft type qualifications. Titov is current on the Su-7, MiG-21, and several other high-performance aircraft. Nikolayev and Leonov are still certified to fly two or three MiG fighter types. Belyayev, Bykovsky, Popovich, Kutachov, and the others are only current on the L-29 trainer. The L-29 is 20 times more reliable than the MiG-21 or Su-7, and the MiG-15 trainer is 4x to 5x more reliable than the high performance types. In general the cosmonauts are against plans to move the air regiment to TsPK from Chkalovsky air field due to greater air space restrictions over Moscow.
