61st anniversary of space age

October 4, 2018

October 4, 2018 is the day when the Humankind marks the 61st anniversary of the start of the Space Age. It was on this day in 1957 that the first artificial Earth satellite was launched, which was made in the USSR, and this day was the birth day of the world spaceflight.

The Soviet spacecraft Sputnik-1 was given reference designation PS-1 (Russian acronym for Simplest Satellite-1), its mass was 83.6 kg, and its diameter was 0.58 m. It was launched from Test Range 5 of the Ministry of Defense of the USSR Tyura-Tam (for the public media this classified name was replaced with Baikonur Cosmodrome) on the launch vehicle Sputnik developed on the basis of the intercontinental ballistic missile R-7.

The first artificial Earth satellite was developed, under the leadership of the farther of practical space flight Sergei Korolev, by scientists M.V. Keldysh, M.K. Tikhonravov, N.S. Lidorenko, G.Y. Maksimov, V.I. Lapko, B.S. Chekunov, A. Bukhtiarov and many others.

The main objectives of the satellite were: to verify calculations and major engineering solutions adopted for the launch; to conduct ionospheric research of propagation of radio waves emitted by the satellite transmitters; to experimentally determine the density of the upper atmosphere from the orbit decay, and to study the operational environment of space hardware.

During the mission which lasted three months, Sputnik-1 made about 1440 orbits around Earth and de-orbited on January 4, 1958.

To mark the 61st anniversary of the first satellite, there will be memorial events and ceremonies in Moscow. On October 4 and 6 IKI RAN (Russian Space Research Institute) will hold Space Science Days 2018 dedicated to the first Earth satellite. The subject of scientific sessions during these days will be planetary exploration. Participants in the science program of the ExoMars-2016 mission will talk about the first months of work in the Martian orbit. There will be reports about key issues in the studies of Mercury, sent to which in just two weeks time is going to be the BepiColombo spacecraft (Russia takes part in the science program of the mission), and about the New Horizons mission which is to fly by a small body in the Kuiper belt on the first day of the next year. The program will end with a presentation about planets beyond the Solar System.

The Memorial Space Museum October 4 through 11 is going to hold a Space Week Space is Nearer in the framework of which there will be a whole series of thematic popular science, educational and presentational events. In particular, within the framework of the Week there will be direct broadcasts of the landing of Soyuz MS-08 (October 4) and the launch of launch vehicle Soyuz-FG carrying crew transportation spacecraft Soyuz MS-10 (October 11), as well as a meeting with pilot cosmonaut, Hero of the USSR Alexander Laveikin.

On November 9, on the premises of the Bauman Moscow State Technical University, there will be Roscosmos Student Day, the main participants in which will be first-year students of engineering universities of Moscow and Moscow Region future employees of design bureaus, institutes and companies in the rocket and space industry.
