RADARSAT Constellation
The RADARSAT Constellation Mission (RCM) is a three-spacecraft fleet of Earth observation satellites operated by the Canadian Space Agency. The RCM's goal is to provide data for climate research and commercial applications including oil exploration, fishing, shipping, etc. With satellites smaller than RADARSAT-2, the RCM will provide new applications—made possible through the constellation approach—as well as continuing to provide C-band radar data to RADARSAT-2 users. One of its most significant improvements is in its operational use of synthetic-aperture radar (SAR) data. The primary goal of RCM is to provide continuous C-band SAR data to RADARSAT-2 users, as SAR imagery at a high temporal resolution is required by several users in the Canadian government. Other improvements include more frequent area coverage of Canada and reduced risk of a service interruption. The RCM will provide the world's most advanced, comprehensive method of maintaining Arctic sovereignty, conduct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth Observation Satellite
An Earth observation satellite or Earth remote sensing satellite is a satellite used or designed for Earth observation (EO) from orbit, including spy satellites and similar ones intended for non-military uses such as environmental monitoring, meteorology, cartography and others. The most common type are Earth imaging satellites, that take satellite images, analogous to aerial photographs; some EO satellites may perform remote sensing without forming pictures, such as in GNSS radio occultation. The first occurrence of satellite remote sensing can be dated to the launch of the first artificial satellite, Sputnik 1, by the Soviet Union on October 4, 1957. Sputnik 1 sent back radio signals, which scientists used to study the ionosphere. The United States Army Ballistic Missile Agency launched the first American satellite, Explorer 1, for NASA’s Jet Propulsion Laboratory on January 31, 1958. The information sent back from its radiation detector led to the discovery of the Earth's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falcon 9 Booster B1050
A Falcon 9 first-stage booster is a reusable rocket booster (rocketry), booster used on the Falcon 9 and Falcon Heavy orbital launch vehicles manufactured by SpaceX. The manufacture of first-stage booster constitutes about 60% of the launch price of a single expended Falcon 9 (and three of them over 80% of the launch price of an expended Falcon Heavy), which led SpaceX to develop a program dedicated to recovery and reuse of these boosters for a significant decrease in launch costs. After multiple attempts, some as early as 2010, at controlling the reentry of the first stage after its separation from the second stage, the first successful controlled landing of a first stage occurred on 22 December 2015, on the first flight of the Falcon 9 Full Thrust, Full Thrust version. Since then, Falcon 9 first-stage boosters have been landed and recovered times out of attempts, including synchronized recoveries of the side-boosters of the Falcon Heavy test flight, Arabsat-6A, USSF-44 and S ...

Spacecraft Launched In 2019
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] |

Earth Observation Satellites Of Canada
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar energy is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technological And Industrial History Of Canada
The technological and industrial history of Canada encompasses the country's development in the areas of transportation, communication, energy, materials, public works, public services (health care), domestic/consumer and defense technologies. Most technologies diffused in Canada came from other places; only a small number actually originated in Canada. For more about those with a Canadian origin, see Invention in Canada. The terms chosen for the "age" described below are both literal and metaphorical. They describe the technology that dominated the period in question but are also representative of a large number of other technologies introduced during the same period. Also of note is the fact that the period of diffusion of a technology can begin modestly and can extend well beyond the "age" of its introduction. To maintain continuity, the treatment of its diffusion is dealt with in the context of its dominant "age". For example, the "Steam Age" here is defined as being from 1840 ...

Synthetic Aperture Radar
Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars. SAR is typically mounted on a moving platform, such as an aircraft or spacecraft, and has its origins in an advanced form of side looking airborne radar (SLAR). The distance the SAR device travels over a target during the period when the target scene is illuminated creates the large ''synthetic'' antenna aperture (the ''size'' of the antenna). Typically, the larger the aperture, the higher the image resolution will be, regardless of whether the aperture is physical (a large antenna) or synthetic (a moving antenna) – this allows SAR to create high-resolution images with comparatively small physical antennas. For a fixed antenna size and orientation, objects which are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
