The paper provides an integrated analysis of the problem of the fast growing field of development and operation of Small Spacecraft (SS) constellations and participation of domestic launch site Plesetsk in solving this problem. It reviews the history of launches from Plesetsk, and describes the current status of work to build up and replenish SS-based orbital constellations. It describes major methods of SS launches. When describing multiple launches of SS on heavy launch vehicles it cites foreign practices of SpaceX Company, as well as lays down the prospects for development of our country’s heavy launch vehicles. As for the small-lift launch vehicles, it cites the experience of launching from Plesetsk of launch-vehicles Rokot and Soyuz-2 Phase 1v. For the super-small-lift launch vehicles, it cites the experience of USA and PRC, as well as our country’s development project of the launch vehicle Irkut, which is planned to be launched from Plesetsk, among other places. As for changes in the configuration of ground space infrastructure, the paper points out a trend towards processing SS at a single common processing facility (there is no need to construct processing facilities for each specific small spacecraft). The paper presents general trends in the system for operation of space facilities. The trends towards standardizing mechanical handling equipment in particular, and processing facilities in general, make it possible to lower development costs and speed up development schedules for advanced small spacecraft. Reducing small spacecraft processing time has a beneficial effect on the operational efficiency of the launch campaign, while the use of mobile checkout equipment makes it possible to quickly put together mobile and flexible processing facilities, the use of which will undoubtedly contribute to shaping the future of our country’s launch system. An important point made in the paper is the conclusion that in spite of our country’s lagging behind in super-small-lift launch vehicles, it has a significant scientific and engineering potential for developing this type of launch vehicles. Regardless of the value of other conclusions of the paper, the key point is that the current state of the ground space infrastructure facilities and the accumulated experience of specialists at Plesetsk make it possible to address the full spectrum of SS launch operations. Key words: small spacecraft, launch vehicles, ground space infrastructure, system for operation of space facilities.

A manager facing the decision whether to proceed with a proposed computer system development project needs to determine whether its benefits are worth more than its costs. This can be done by applying a simple mathematical formula to calculate the project's 'net worth', as the sum of the annual benefits obtainable during the system's life span, less its development costs. The formula recognizes that a system's annual benefit, comprising enhanced informational value plus reduction In data processing cost, will change as a result of obsolescence, cost of capital, organizational growth and learning.

Despite advances in diagnosis and treatment, tuberculosis (TB) continues to be one of the essential health problems throughout the world. Turkey is considered to be endemic for TB. In this study, we analyzed the distribution of Mycobacterium species, compare the diagnostic methods, and susceptibilities to anti-tuberculosis drugs of TB isolates. The aim was to document the current status and to provide a frame of reference for future studies. In this study, 278 Mycobacterium species isolated from 7,480 patients between September 2015 and June 2019 were included. Löwenstein-Jensen medium (LJ) and MGIT 960 were used for the isolation of strains. Susceptibility to 1st-line anti-tuberculosis drugs was determined. Positivity rates in clinical samples were as follows: 1.4% for direct microscopic acid-fast bacilli (AFB) detection, 3.4% for growth on the LJ, and 3.7% for growth on MGIT-960. Two hundred thirty-three isolates were identified as Mycobacterium tuberculosis complex (MTBC) and 45 were non-tuberculous mycobacteria (NTMs). Eleven of the NTMs (24.4%) were Mycobacterium fortuitum group isolates, and eight NTMs (17.7%) were Mycobacterium abscessus complex isolates. A number of patients diagnosed with tuberculosis peaked twice between the ages of 20–31 and 60–71. A hundred and eighty-two MTBC isolates (78.1%) were susceptible to all 1st-line anti-tuberculosis drugs, while 51 isolates (21.9%) were resistant to at least one drug tested. The multidrug-resistant tuberculosis rate was 13.7% among resistant strains and 3% in all strains. The liquid cultures were better for detection of both MTBC and NTMs isolates. The data demonstrate that MTBC continues to be challenge for this country and indicates the need for continued surveillance and full-spectrum services of mycobacteriology laboratory and infectious diseases.

The paper addresses the problem of cooperative development of ground space infrastructure and orbital constellation of Earth remote sensing spacecraft (ERS). In view of the considerable number of elements in space and ground segments of a heterogenous space ERS system, a mechanism is required for developing its concepts involving acquiring updated inputs for determining measures to optimize the ERS ground segment configuration geography-wise and outfit receiving systems for receiving the mission payload data from high-performance ERS spacecraft. The paper describes trends in the development of equipment and technologies for transmitting ERS mission payload data, in particular, the current status of the high data rate optical backbone network in order to determine possible locations for ERS Ground Segment elements. It introduces indicators which provide system-level characterization of the capabilities for a distributed network of data receiving stations. Based on the obtained data, system-level patterns were determined in the development of the ground segment for receiving the ERS mission payload data depending on the state of the ERS orbital constellation, driving further development of growth strategy for the ERS ground space infrastructure. Key words: Earth remote sensing, concept, mission payload data, receiving system, data reception station.

The article briefly discusses the key achievements of the enterprise over 75 years from the formation of OKB-1 headed by S.P. Korolev for producing intercontinental range missiles to the current status of RSC Energia being the country’s and world leader in manned space flight. The developed intercontinental missiles R-7 and a closed-loop oxygen-hydrocarbon liquid-propellant rocket engine provided the basis for developing integrated launch vehicles which were used to launch the world's first Earth satellite, the first cosmonaut on the Earth, automatic interplanetary stations to the Moon, Venus, Mars. The diversification of the enterprise impeded S.P. Korolev to concentrate on manned space flights, and he initiated the transfer of development and manufacture of combat missiles to Makeyev DB, integrated launch vehicles to TsSKB Progress, communication and other satellites to M.F. Reshetnev ISS, lunar and interplanetary stations to S.A.Lavochkin NPO. In the 1980s under the guidance of V.P. Glushko the Energia super-heavy launch vehicle and Energia-Buran system in unmanned configuration were developed and successfully launched on the first try. The Salyut manned single-module orbital stations, Mir multifunctional multi-module space laboratory and successfully operating upgraded manned transportation (Soyuz) and logistics (Progress) spacecraft were developed. In the hard times of 1990s, RSC Energia under the guidance of Yu.P. Semenov saved the national cosmonautics through commercial research performed on the Mir station. At present, by launching three additional modules RSC Energia is completing assembly and integration of the Russian Segment into the International Space Station. Keywords. ОKB-1, S.P.Korolev RSC Energia, V.P. Glushko, Yu.S. Semenov, integrated launch vehicle, orbital station, crew transportation spacecraft, logistics transportation spacecraft, International Space Station.
