Paz (satellite)
Paz (Spanish for "Peace") is a Spanish Earth observation and reconnaissance satellite launched on 22 February 2018. It is Spain's first spy satellite. The satellite is operated by Hisdesat. ''Paz'' was previously referred to as SEOSAR (Satélite Español de Observación SAR). Overview For observational purposes, ''Paz'' uses a synthetic aperture radar (SAR) to collect images of Earth for governmental and commercial use, as well as other ship tracking and weather sensors, which enables high-resolution mapping of large geographical areas at day and night. The X-band radar imaging payload operates at a wavelength of , or a frequency of 9.65 gigahertz. The ''Paz'' satellite is operated in a constellation with the German SAR fleet TerraSAR-X and TanDEM-X on the same orbit. The collaboration was agreed on by both Hisdesat and former European aerospace manufacturer Astrium, operator of the two other satellites. The high-resolution images will be used for military operations, bor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kosmotras
The International Space Company Kosmotras or ISC Kosmotras (russian: ЗАО Международная космическая компания “Космотрас”) is a joint project, between Russia, Ukraine, and Kazakhstan, established in 1997. It developed and now operates a commercial expendable launch system using the Dnepr rocket. The Dnepr is a converted decommissioned SS-18 ICBM. ISC Kosmotras conducts Dnepr launches from Baikonur Cosmodrome and Yasny launch base in Dombarovskiy, Russia. In February 2015, following a year of strained relations as a result of a Russian military intervention into Ukraine, Russia announced that it would sever its "joint program with Ukraine to launch Dnepr rockets". ISC Kosmotras said it would honor its remaining launch contracts. Of the three launches planned for 2015, only one took place. As of 2016, it appears ISC Kosmotras no longer has customers, and thus whether the company is operational or not is uncertain. In May 2017, ISC Ko ...

Spacecraft Launched In 2018
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit (space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Satellites Of Spain
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propuls ...

Crew Boat
A crew boat, also called a crewboat, crew transfer vessel, fast support vessel, fast supply vessel or fast intervention supply vessel, is a vessel specialized in the transport of offshore support personnel, deck cargo, and below-deck cargo such as fuel and potable water to and from offshore installations such as oil platforms, drilling rigs, drill and dive ships or wind farms. Crew boats range in size from small, vessels working on bays, sounds and inland waterways to vessels that work as much as offshore. Crew boats typically are constructed of aluminum and offshore vessels are most often powered by four-six turbo-charged diesel engines and propelled by conventional ship's screws or water jets. In the United States, crew boats may carry any number of passengers up to the maximum noted on the vessel's United States Coast Guard certificate of inspection. For most offshore crew boats, the maximum number of passengers, accommodated in airline-style seats, is between 50 and 100. ...

Payload Fairing
A payload fairing is a nose cone used to protect a spacecraft payload against the impact of dynamic pressure and aerodynamic heating during launch through an atmosphere. An additional function on some flights is to maintain the cleanroom environment for precision instruments. Once outside the atmosphere the fairing is jettisoned, exposing the payload to outer space. The standard payload fairing is typically a cone-cylinder combination, due to aerodynamic considerations, although other specialized fairings are in use. The type of fairing which separates into two halves upon jettisoning is called a clamshell fairing by way of analogy to the bifurcating shell of a clam. In some cases the fairing may enclose both the payload and the upper stage of the rocket, such as on Atlas V and Proton M. If the payload is attached both to the booster's core structures and to the fairing, the payload may still be affected by the fairing's bending loads, as well as inertia loads due to vibrations ...

Sun-synchronous Orbit
A Sun-synchronous orbit (SSO), also called a heliosynchronous orbit, is a nearly polar orbit around a planet, in which the satellite passes over any given point of the planet's surface at the same local mean solar time. More technically, it is an orbit arranged so that it precesses through one complete revolution each year, so it always maintains the same relationship with the Sun. Applications A Sun-synchronous orbit is useful for imaging, reconnaissance, and weather satellites, because every time that the satellite is overhead, the surface illumination angle on the planet underneath it is nearly the same. This consistent lighting is a useful characteristic for satellites that image the Earth's surface in visible or infrared wavelengths, such as weather and spy satellites, and for other remote-sensing satellites, such as those carrying ocean and atmospheric remote-sensing instruments that require sunlight. For example, a satellite in Sun-synchronous orbit might ascend acros ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Falcon 9 Block 3
Falcon 9 Full Thrust (also known as Falcon 9 v1.2, with variants Block 1 to Block 5) is a partially reusable medium-lift launch vehicle, designed and manufactured by SpaceX. Designed in 2014–2015, Falcon 9 Full Thrust began launch operations in December 2015. As of , Falcon 9 Full Thrust had performed launches without any failures. Based on the Lewis point estimate of reliability, this rocket is the most reliable orbital launch vehicle currently in operation. On April 8, 2016, the ''Full Thrust'' version of the Falcon 9 family was the first launch vehicle on an orbital trajectory to successfully vertically land a first stage. The landing followed a technology development program conducted from 2013 to 2015. Some of the required technology advances, such as landing legs, were pioneered on the Falcon 9 v1.1 version, but that version never landed intact. Starting in 2017, previously flown first-stage boosters were reused to launch new payloads into orbit. This quickly becam ...
