Credit: NASA
Russian lunar orbiter. 2 launches, 1966.03.01 (Cosmos 111) to 1966.03.31 (Luna 10).

The E-6S artificial lunar satellite was designed for the investigation of circumlunar space; development of onboard systems for putting a station into a selenocentric (circumlunar) orbit. Scientific instruments included a gamma-ray spectrometer for energies between 0.3--3 MeV, a triaxial magnetometer, a meteorite detector, instruments for solar-plasma studies, and devices for measuring infrared emissions from the Moon and radiation conditions of the lunar environment.

Gravitational studies were also conducted. The spacecraft played back to Earth the `Internationale' during the Twenty-third Congress of the Communist Party of the Soviet Union. Battery powered and operated for 460 lunar orbits and 219 active data transmissions before radio signals were discontinued.

Gross mass: 1,597 kg (3,520 lb).
First Launch: 1966.03.01.
Last Launch: 1966.03.31.
Number: 2 .

  • Soyuz The Russian Soyuz spacecraft has been the longest-lived, most adaptable, and most successful manned spacecraft design. In production for fifty years, more than 240 have been built and flown on a wide range of missions. The design will remain in use with the international space station well into the 21st century, providing the only manned access to the station after the retirement of the shuttle in 2011. More...

Associated Launch Vehicles
  • Soyuz Russian orbital launch vehicle. The world's first ICBM became the most often used and most reliable launch vehicle in history. The original core+four strap-on booster missile had a small third stage added to produce the Vostok launch vehicle, with a payload of 5 metric tons. Addition of a larger third stage produced the Voskhod/Soyuz vehicle, with a payload over 6 metric tons. Using this with a fourth stage, the resulting Molniya booster placed communications satellites and early lunar and planetary probes in higher energy trajectories. By the year 2000 over 1,628 had been launched with an unmatched success rate of 97.5% for production models. Improved models providing commercial launch services for international customers entered service in the new millenium, and a new launch pad at Kourou was to be inaugurated in 2009. It appeared that the R-7 could easily still be in service 70 years after its first launch. More...

Associated Launch Sites
  • Baikonur Russia's largest cosmodrome, the only one used for manned launches and with facilities for the larger Proton, N1, and Energia launch vehicles. The spaceport ended up on foreign soil after the break-up of Soviet Union. The official designations NIIP-5 and GIK-5 are used in official Soviet histories. It was also universally referred to as Tyuratam by both Soviet military staff and engineers, and the US intelligence agencies. Since the dissolution of the Soviet Union the Russian Federation has insisted on continued use of the old Soviet 'public' name of Baikonur. In its Kazakh (Kazak) version this is rendered Baykonur.

The Luna 10 robot orbiter has successfully entered moon orbit, conducted two radio communications sessions, including broadcast back to the earth of the "International", the Socialist hymn, to the 23rd Party Congress. Bushuev from OKB-1 is seeking cosmonaut representatives for the commission that will inspect the mock-up of the L1 circumlunar spacecraft. Kamanin nominates Gagarin, Komarov, Nikitin, Frolov, Smirnov, and others. Kamanin informs OKB-1 that he has obtained the support of the PVO and RVSN for the completion and flight of Voskhod s/n 7, 8, and 9. A letter to Smirnov asking for those fights to be conducted will be drafted.
