Soyuz (rocket)
The Soyuz (, meaning "union", GRAU index 11A511) was a Soviet expendable carrier rocket designed in the 1960s by OKB-1 and manufactured by State Aviation Plant No. 1 in Kuybyshev, Soviet Union. It was commissioned to launch Soyuz spacecraft as part of the Soviet human spaceflight program, first with eight uncrewed test flights, followed by the first 19 crewed launches. The original Soyuz also propelled four test flights of the improved Soyuz 7K-T capsule between 1972 and 1974. It flew 30 successful missions over ten years and suffered two failures. The Soyuz 11A511 type, a member of the R-7 family of rockets, first flew in 1966 and was an attempt to standardize the R-7 family and get rid of the variety of models that existed up to that point. It was basically a Molniya 8K78M without the Blok L stage. It featured the 8D74M RD-107 and the RD-110 engines from the 8K78M, The new, uprated core stage and strap-ons became standard for all R-7 derived launch vehicles to replace ...

Baikonur Cosmodrome
The Baikonur Cosmodrome is a spaceport operated by Russia within Kazakhstan. Located in the Kazakh city of Baikonur, it is the largest operational space launch facility in terms of area. All Russian Human spaceflight, crewed spaceflights are launched from Baikonur. Situated in the Kazakh Steppe, some above sea level, it is to the east of the Aral Sea and north of the Syr Darya. It is close to Töretam, a station on the Trans-Aral Railway. Russia, as the official successor state to the Soviet Union, has retained control over the facility since 1991; it originally assumed this role through the post-Soviet Commonwealth of Independent States (CIS), but ratified an agreement with Kazakhstan in 2005 that allowed it to lease the spaceport until 2050. It is jointly managed by Roscosmos and the Russian Aerospace Forces. In 1955, the Ministry of Defense (Soviet Union), Soviet Ministry of Defense issued a decree and founded the Baikonur Cosmodrome. It was originally built as the chief ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soyuz (spacecraft)
Soyuz () is a series of spacecraft which has been in service since the 1960s, having made more than 140 flights. It was designed for the Soviet space program by the Korolev Design Bureau (now Energia (corporation), Energia). The Soyuz succeeded the Voskhod spacecraft and was originally built as part of the Soviet crewed lunar programs. It is launched atop the similarly named Soyuz (rocket family), Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan. Following the Soviet Union's dissolution, Roscosmos, the Russian space agency, continued to develop and utilize the Soyuz. Between the Space Shuttle retirement, Space Shuttle's 2011 retirement and the SpaceX Crew Dragon's 2020 debut, Soyuz was the sole means of crewed transportation to and from the International Space Station, a role it continues to fulfill. The Soyuz design has also influenced other spacecraft, including China's Shenzhou (spacecraft), Shenzhou and Russia's Progress (spacecraft), Progress cargo vehicle. The Soyu ...

Low Earth Orbit
A low Earth orbit (LEO) is an geocentric orbit, orbit around Earth with a orbital period, period of 128 minutes or less (making at least 11.25 orbits per day) and an orbital eccentricity, eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, peaking in number at an altitude around , while the farthest in LEO, before medium Earth orbit (MEO), have an altitude of 2,000 km, about one-third of the Earth radius, radius of Earth and near the beginning of the Van Allen radiation belt#Inner belt, inner Van Allen radiation belt. The term ''LEO region'' is used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital spaceflight, sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. No human spaceflights other than the lunar missions of the Apollo program (1968-1972) have gone beyond L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soyuz 7K-T
The second generation of the Soyuz spacecraft, the ''Soyuz 7K-T'', comprised Soyuz 12 through Soyuz 40 (1973–1981). In the wake of the Soyuz 11 tragedy, the spacecraft was redesigned to accommodate two cosmonauts who would wear pressure suits at all times during launch, docking, undocking, and reentry. The place of the third cosmonaut was taken by extra life-support systems. Finally, the 7K-T, being intended purely as a space station ferry, had no solar panels, instead sporting two large whip antennas in their place. As a result, it relied on batteries which only provided enough power for two days of standalone flight. The idea was that the Soyuz would recharge while docked with a Salyut space station, but in the event of a docking or other mission failure (which ended up happening on several occasions), the crew was forced to power off everything except communications and life support systems until they could reenter. Two test flights of the 7K-T were conducted prior to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Spaceflight
Human spaceflight (also referred to as manned spaceflight or crewed spaceflight) is spaceflight with a crew or passengers aboard a spacecraft, often with the spacecraft being operated directly by the onboard human crew. Spacecraft can also be telerobotic, remotely operated from ground stations on Earth, or Autonomous robot, autonomously, without any direct human involvement. People trained for spaceflight are called astronauts (American or other), ''cosmonauts'' (Russian), or ''taikonauts'' (Chinese); and non-professionals are referred to as spaceflight participants or ''spacefarers''. The first human in space was Soviet Union, Soviet cosmonaut Yuri Gagarin, who launched as part of the Soviet Union's Vostok program on Cosmonautics Day, 12 April 1961 at the beginning of the Space Race. On 5 May 1961, Alan Shepard became the first American in space, as part of Project Mercury. Humans traveled to the Moon nine times between 1968 and 1972 as part of the United States' Apollo progr ...

Soyuz Programme
The Soyuz programme ( , ; , meaning "Union") is a human spaceflight programme initiated by the Soviet Union in the early 1960s. The Soyuz spacecraft was originally part of a Moon landing project intended to put a Soviet cosmonaut on the Moon. It was the third Soviet human spaceflight programme after the Vostok (1961–1963) and Voskhod (1964–1965) programmes. The programme consists of the Soyuz capsule and the Soyuz rocket and is now the responsibility of Roscosmos. After the retirement of the Space Shuttle in 2011, the Soyuz was the only way for humans to get to the International Space Station (ISS) until 30 May 2020 when Crew Dragon flew to the ISS for the first time with astronauts.

Carrier Rocket
A launch vehicle is typically a rocket-powered vehicle designed to carry a payload (a crewed spacecraft or satellites) from Earth's surface or lower atmosphere to outer space. The most common form is the ballistic missile-shaped multistage rocket, but the term is more general and also encompasses vehicles like the Space Shuttle. Most launch vehicles operate from a launch pad, supported by a launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to high operating costs. An orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles use chemical propellants such as solid fuel, liquid hydrogen, kerosene, liquid oxygen, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Expendable Launch System
An expendable launch system (or expendable launch vehicle/ELV) is a launch vehicle that can be launched only once, after which its components are destroyed during reentry or impact with Earth, or discarded in space. ELVs typically consist of several rocket stages that are discarded sequentially as their fuel is exhausted and the vehicle gains altitude and speed. As of 2024, fewer and fewer satellites and human spacecraft are launched on ELVs in favor of reusable launch vehicles. However, there are many instances where a ELV may still have a compelling use case over a reusable vehicle. ELVs are simpler in design than reusable launch systems and therefore may have a lower production cost. Furthermore, an ELV can use its entire fuel supply to accelerate its payload, offering greater payloads. ELVs are a proven technology in widespread use for many decades. Current operators Arianespace China ISRO During the 1960s and 1970s, India initiated its own launch vehicle program ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
