Briz (rocket Stage)
The Briz-K, Briz-KM and Briz-M ( meaning ''Breeze-K, KM and M'') are Russian liquid-propellant rocket orbit insertion upper stages manufactured by Khrunichev State Research and Production Space Center and used on the Proton-M and Angara A5. The upper stages were also used on Rokot, one of Russia's smaller launchers, before its retirement in 2019. Characteristics Briz-K and Briz-KM Briz-K, GRAU index 14S12, is a single-piece structure with a conical tank compartment and the engine located in a recess in the fuel tank. Briz-KM ( GRAU index 14S45) is an improved version of Briz-K. The Briz-K and Briz-KM were used as a third stage of the Rokot launch vehicles. Briz-M Briz-M, GRAU index 14S43, is designed for injecting large payloads into a low, medium-height or high geosynchronous orbit. Briz-M is a twin upper stage consisting of a core module (using Briz-KM as the baseline) and a jettisonable add-on toroidal tank surrounding the core. It is powered by a pump-fed gimba ...

Blok DM-03
The Blok DM-03 (, GRAU index: 11S861-03), is a Russian upper stage used as an optional fourth stage on the Proton-M and Angara A5 heavy-lift rockets. Three have been launched, the first in December 2010; the first two launches failed before fourth stage ignition, the first as a result of a problem with the Blok DM's fuel load. Some versions are also known as Orion. Initial versions of the Blok DM-03 are powered by a single RD-58M engine, burning RG-1 and liquid oxygen. The last evolution is powered by the improved RD-58MF, a less powerful but more efficient evolution of the venerable engine. It can carry 25% more propellant than the Blok DM-2, which it replaced as a Proton upper stage for some government launches. However most government launches and all commercial missions use the Briz-M instead. The payloads for the first two Blok DM-03 launches were groups of three Uragan-M satellites for the GLONASS programme, with further missions slated to carry three more Uragan-M sa ...

Nauka (ISS Module)
''Nauka'' (), also known as the ''Multipurpose Laboratory Module, Upgrade'' (MLM-U, ), is the primary laboratory of the Russian Orbital Segment of the International Space Station (ISS). Serving alongside the ''Rassvet'' and ''Poisk'' mini-research modules, Nauka conducts scientific experiments and stores research equipment. Originally built as a backup for ''Zarya'', the very first module of the ISS, ''Nauka'''s construction was halted in the late 1990s, when it was about 70% complete. After exploring various options, Roscosmos decided to convert the partially completed module into a laboratory. While the initial target launch date was set for 2007, and outfitting equipment for Nauka was delivered by Space Shuttle ''Atlantis'' in 2010 attached to the ''Rassvet'' module, numerous delays and technical issues delayed the launch by 14 years. ''Nauka'' finally launched on 21 July 2021 at 14:58:25UTC from the Baikonur Cosmodrome atop a Proton-M rocket. Like most of the Russian mo ...

RD-253
The RD-253 () and its later variants, the RD-275 and RD-275M, are liquid-propellant rocket engines developed in the Soviet Union by Energomash. The engines are used on the first stage of the Proton launch vehicle and use an oxidizer-rich staged combustion cycle to power the turbopumps. The engine burns a hypergolic mixture of unsymmetrical dimethylhydrazine (UDMH) fuel with dinitrogen tetroxide () oxidizer, which are highly toxic, but storable at room temperature. History Development of the RD-253 started in 1961. Preliminary investigations and development of the engine and its further production was performed under the guidance of Valentin Glushko and finished in 1963. The RD-253 uses an oxidiser-rich staged combustion cycle. It was used for the first time in July 1965, when six engines powered the first stage of the Proton rocket. Development and production of RD-253 was a qualitative leap forward for rocketry of that time by achieving high levels of thrust, specific impuls ...

Blok D
Blok D () is an upper stage used on Soviet and later Russian expendable launch systems, including the N1, Proton-K and Zenit. The stage (and its derivatives) has been included in more than 320 launched rockets . By 2002 its modification Blok DM had a 97% success rate in 218 flights since 1974, and 43 successful missions in 1997–2002. The stage was developed in the 1960s as the fifth stage (' Д' is the fifth letter in the Cyrillic alphabet) for the powerful N1 rocket used in the Soviet crewed lunar programs. The stage first flew in March 1967 while testing the Zond spacecraft as a part of those programs. During crewed lunar flight Blok D would be used for mid-course corrections on the flight to the Moon, then to place the lunar orbiter and lander into a lunar orbit, and decelerate moon-lander out onto its landing trajectory. Blok D was also included as fourth stage of Proton-K and as such flew on uncrewed Soviet missions to Moon, Mars (Mars 3) and Venus. It was used ...

Baikonur Cosmodrome Site 200
Site 200 at the Baikonur Cosmodrome is a launch site used by Proton rockets. It consists of two launch pads, areas 39 and 40. Area 39 is currently (as of 2021) used for Proton-M launches, including commercial flights conducted by International Launch Services. Area 40 is currently (as of 2021) inactive, as it was slated to be rebuilt as a launch site for the Angara rocket. Although the project was relocated to Site 250, Area 40 was not put back into service. A number of planetary probes have been launched from Site 200. Venera 14, Venera 15, Vega 1, Fobos 1, the failed Mars-96, and ExoMars were launched from area 39. Venera 13, Venera 16, Vega 2, Fobos 2 were launched from Area 40.

RD-0210
The RD-0210 (, GRAU index: 8D411K) is also known as the RD-465. It and its twin, the RD-0211, are rocket engines using unsymmetrical dimethylhydrazine (UDMH) as fuel and dinitrogen tetroxide (N2O4) as oxidizer in an oxidizer rich staged combustion cycle. They have a single nozzle, possess thrust vectoring and are the latest evolution in the RD-0203/4 lineage. They are the engines used on the Proton second stage. The RD-0213 is a fixed nozzle variation that is used on the RD-0212 module of the Proton third stage. Development When Chelomey's OKB-52 started their UR-200 ICBM project, they requested S. A. Kosberg's OKB-154 to develop the propulsion. They decided to use the same basic block for both the first and second stage. But to achieve the required performance, Kosberg had to develop a staged combustion engine, a then extremely aggressive feat. Only M. V. Melnikov of OKB-1 had designed a staged combustion engine before, the S1.5400, and it used a different propellant mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heavy-lift Launch Vehicle
A heavy-lift launch vehicle (HLV) is an orbital launch vehicle capable of lifting payloads between (by NASA classification) or between (by Russian classification) into low Earth orbit (LEO).50t payloads" Heavy-lift launch vehicles often carry payloads into higher-energy orbits, such as geosynchronous transfer orbit (GTO) or heliocentric orbit (HCO). An HLV is between a medium-lift launch vehicle and a super heavy-lift launch vehicle. History and design Government The first heavy-lift launch vehicles in the 1960s included the US Saturn IB and the Soviet Proton. Saturn IB was designed to carry the Apollo spacecraft into orbit and had increased engine thrust and a redesigned second stage from its predecessor. Proton was originally designed to be a large intercontinental ballistic missile (ICBM). Russia still operates variants of the Proton , although it is expected to be phased out in favor of the Angara A5. NASA introduced the Space Shuttle as the first partially reusab ...
