ISS-RapidScat
ISS-RapidScat was an instrument mounted to the International Space Station ''Columbus'' module that measured wind speeds. It was launched aboard SpaceX CRS-4 in September 2014 and operated until August 2016. ISS-RapidScat was a scatterometer designed to support weather forecasting by bouncing microwaves off the ocean's surface to measure wind speed via wind waves. It featured a rotating radar dish that operated at 13.4 GHz ( Ku band). It could collect data between 51.6 degrees north and south latitude, with a swath . The ISS-RapidScat program was initiated in response to the failure of the QuikSCAT satellite's antenna rotation mechanism in November 2009. While the spacecraft continued to function, it could only gather data in one direction, significantly limiting its data collection ability. ISS-RapidScat was built by the Jet Propulsion Laboratory from elements of QuikSCAT's SeaWinds instrument engineering model, originally used to validate that instrument's flight har ...

Columbus (ISS Module)
''Columbus'' is a science laboratory that is part of the International Space Station (ISS) and is the largest single contribution to the ISS made by the European Space Agency (ESA). Like the '' Harmony'' and ''Tranquility'' modules, the ''Columbus'' laboratory was constructed in Turin, Italy by Thales Alenia Space. The functional equipment and software of the lab was designed by EADS in Bremen, Germany. It was also integrated in Bremen before being flown to the Kennedy Space Center (KSC) in Florida in an Airbus Beluga. It was launched aboard on February 7, 2008, on flight STS-122. It is designed for ten years of operation. The module is controlled by the Columbus Control Centre, located at the German Space Operations Center, part of the German Aerospace Center in Oberpfaffenhofen near Munich, Germany. The European Space Agency has spent €1.4 billion (about US$2 billion) on building ''Columbus'', including the experiments it carries and the ground control infrastructure n ...

Scatterometer
A scatterometer or diffusionmeter is a scientific instrument to measure the return of a beam of light or radar waves scattered by diffusion in a medium such as air. Diffusionmeters using visible light are found in airports or along roads to measure horizontal visibility. Radar scatterometers use radio or microwaves to determine the normalized radar cross section (σ0, "sigma zero" or "sigma naught") of a surface. They are often mounted on weather satellites to find wind speed and direction, and are used in industries to analyze the roughness of surfaces. Optical Optical diffusionmeters are devices used in meteorology to find the optical range or the horizontal visibility. They consist of a light source, usually a laser, and a receiver. Both are placed at a 35° angle downward, aimed at a common area. Lateral scattering by the air along the light beam is quantified as an attenuation coefficient. Any departure from the clear air extinction coefficient (e.g. in fog) is measured an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Space Station
The International Space Station (ISS) is the largest modular space station currently in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). The ownership and use of the space station is established by intergovernmental treaties and agreements. The station serves as a microgravity and space environment research laboratory in which scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. The ISS is suited for testing the spacecraft systems and equipment required for possible future long-duration missions to the Moon and Mars. The ISS programme evolved from the Space Station ''Freedom'', a 1984 American proposal to construct a permanently crewed Earth-orbiting station, and the contemporaneous Soviet/Russian '' Mir-2'' proposal from 1976 with similar aims. The ISS is the ninth space station to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SpaceX CRS-4
SpaceX CRS-4, also known as SpX-4, was a Commercial Resupply Service mission to the International Space Station (ISS), contracted to NASA, which was launched on 21 September 2014 and arrived at the space station on 23 September 2014. It was the sixth flight for SpaceX's uncrewed Dragon cargo spacecraft, and the fourth SpaceX operational mission contracted to NASA under a Commercial Resupply Services contract. The mission brought equipment and supplies to the space station, including the first 3D printer to be tested in space, a device to measure wind speed on Earth, and small satellites to be launched from the station. It also brought 20 mice for long-term research aboard the ISS. Launch history After a scrub due to poor weather conditions on 20 September 2014, the launch occurred on 21 September 2014 at 05:52 UTC from Cape Canaveral Air Force Station (CCAFS) in Florida. Primary payload NASA contracted for the CRS-4 mission and therefore determined the primary pay ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latitude
In geography, latitude is a coordinate that specifies the north– south position of a point on the surface of the Earth or another celestial body. Latitude is given as an angle that ranges from –90° at the south pole to 90° at the north pole, with 0° at the Equator. Lines of constant latitude, or ''parallels'', run east–west as circles parallel to the equator. Latitude and ''longitude'' are used together as a coordinate pair to specify a location on the surface of the Earth. On its own, the term "latitude" normally refers to the ''geodetic latitude'' as defined below. Briefly, the geodetic latitude of a point is the angle formed between the vector perpendicular (or ''normal'') to the ellipsoidal surface from the point, and the plane of the equator. Background Two levels of abstraction are employed in the definitions of latitude and longitude. In the first step the physical surface is modeled by the geoid, a surface which approximates the mean sea level over the ocean ...

SpaceX Dragon
American private space transportation company SpaceX has developed and produced several spacecraft named Dragon. The first family member, now referred to as Dragon 1, flew 23 cargo missions to the ISS between 2010 and 2020 before being retired. With this first version not designed for carrying astronauts, it was funded by NASA with $396 million awarded through the Commercial Orbital Transportation Services (COTS) program, with SpaceX being announced as a winner of the first round of funding on August 18, 2006. SpaceX developed its Dragon 2 spacecraft starting in 2014, with a cargo version and a crewed version. It entered service in 2019 with the Demo-1 flight, and performed its first flight with astronauts on May 30, 2020, during the Crew Dragon Demo-2 flight. SpaceX also investigated a version named Red Dragon for Mars exploration, but the project did not go forward. A version named Dragon XL Is proposed to provide Gateway Logistics Services to the Lunar Gateway. Name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calibration
In measurement technology and metrology, calibration is the comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy. Such a standard could be another measurement device of known accuracy, a device generating the quantity to be measured such as a voltage, a sound tone, or a physical artifact, such as a meter ruler. The outcome of the comparison can result in one of the following: * no significant error being noted on the device under test * a significant error being noted but no adjustment made * an adjustment made to correct the error to an acceptable level Strictly speaking, the term "calibration" means just the act of comparison and does not include any subsequent adjustment. The calibration standard is normally traceable to a national or international standard held by a metrology body. BIPM Definition The formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the fo ...

Hurricane Simon (2014)
The 2014 Pacific hurricane season was the fifth-busiest season since reliable records began in 1949, alongside the 2016 season. The season officially started on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific; they both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. Entering the season, expectations of tropical activity were high, with most weather agencies predicting a near or above average season. The season began with an active start, with three tropical cyclones developing before June 15, including two Category 4 hurricanes, of which one became the strongest tropical cyclone ever recorded in May in the East Pacific. After a less active period in late June and early July, activity once again picked up in late July. Activity increased in August, which featured four major hurricanes, and persisted throughout September and October. However, acti ...

Hurricane Patricia
Hurricane Patricia was the strongest tropical cyclone on record worldwide in terms of wind speed and the second-most intense on record worldwide in terms of pressure, behind Typhoon Tip in 1979, with a minimum atmospheric pressure of 872 mbar (hPa; ). Originating from a sprawling disturbance near the Gulf of Tehuantepec, south of Mexico, in mid-October 2015, Patricia was first classified a tropical depression on October 20. Initial development was slow, with only modest strengthening within the first day of its classification. The system later became a tropical storm and was named Patricia, the twenty-fourth named storm of the annual hurricane season. Exceptionally favorable environmental conditions fueled explosive intensification on October 22. A well-defined eye developed within an intense central dense overcast and Patricia grew from a tropical storm to a Category 5 hurricane in just 24 hours—a near-record pace. On October 23, the hurricane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Hurricane Center
The National Hurricane Center (NHC) is the division of the United States' NOAA/National Weather Service responsible for tracking and predicting tropical weather systems between the Prime Meridian and the 140th meridian west poleward to the 30th parallel north in the northeast Pacific Ocean and the 31st parallel north in the northern Atlantic Ocean.
