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-3
SpaceX CRS-3, also known as SpX-3, was a Commercial Resupply Service mission to the International Space Station (ISS), contracted to NASA, which was launched on 18 April 2014. It was the fifth flight for SpaceX's uncrewed Dragon cargo spacecraft and the third SpaceX operational mission contracted to NASA under a Commercial Resupply Services (CRS-1) contract. This was the first launch of a Dragon capsule on the Falcon 9 v1.1 launch vehicle, as previous launches used the smaller v1.0 configuration. It was also the first time the F9 v1.1 has flown without a payload fairing, and the first experimental flight test of an ocean landing of the first stage on a NASA/Dragon mission. The Falcon 9 with CRS-3 on board launched on time at 19:25 UTC on 18 April 2014, and was grappled on 20 April at 11:14 UTC by Expedition 39 commander Koichi Wakata. The spacecraft was berthed to the ISS from 14:06 UTC on that day to 11:55 UTC on 18 May 2014. CRS-3 then successfully de-orbited and splashed ...

Secondary Payload
Secondary payload, also known as rideshare payload, is a smaller-sized payload transported to orbit on a launch vehicle that is mostly paid for—and with the date and time of launch and the orbital trajectory determined—by the entity that contracts and pays for the primary launch. As a result, the secondary payload typically obtains a substantially reduced price for transportation services to orbit, by accepting a trade off of the loss of control once the contract is signed and the payload is delivered to the launch vehicle supplier for integration to the launch vehicle. These tradeoffs typically include having little or no control over the launch date/time, the final orbital parameters, or the ability to halt the launch and remove the payload should a payload failure occur during ground processing prior to launch, as the ''primary payload'' typically purchases all of these launch property rights via contract with the launch services provider.

Rodent Research Hardware System
NASA's Rodent Research Hardware System provides a research platform aboard the International Space Station for long-duration experiments on rodents in space. Such experiments will examine how microgravity affects the rodents, providing information relevant to human spaceflight, discoveries in basic biology, and knowledge that can help treat human disease on Earth. Background Based on the recommendations from the National Academies of Sciences, Engineering, and Medicine report Recapturing a Future for Space Exploration: Life and Physical Sciences Research for a New Era (2011). The report included a recommendation that NASA establish a rodent research facility aboard the International Space Station designated as a national laboratory “as soon as possible” to enable high-priority, long duration rodent studies. The goal was to conduct studies of durations up to 6 months. As mice and rats have life spans of at most 5 years the “studies on these rodents in space have the potent ...

Dual-energy X-ray Absorptiometry
Dual-energy X-ray absorptiometry (DXA, or DEXA) is a means of measuring bone mineral density (BMD) using spectral imaging. Two X-ray beams, with different energy levels, are aimed at the patient's bones. When soft tissue absorption is subtracted out, the bone mineral density (BMD) can be determined from the absorption of each beam by bone. Dual-energy X-ray absorptiometry is the most widely used and most thoroughly studied bone density measurement technology. The DXA scan is typically used to diagnose and follow osteoporosis, as contrasted to the nuclear bone scan, which is sensitive to certain metabolic diseases of bones in which bones are attempting to heal from infections, fractures, or tumors. It is also sometimes used to assess body composition. Physics Soft tissue and bone have different attenuation coefficients to X-rays. A single X-ray beam passing through the body will be attenuated by both soft tissue and bone, and it is not possible to determine, from a single beam, ...

Center For The Advancement Of Science In Space
The Center for the Advancement of Science in Space (CASIS), a non-profit organization, is the manager of the International Space Station United States National Laboratory, a US government-funded laboratory with principal research facilities located in the United States Orbital Segment of the International Space Station (ISS). History The 2005 NASA Authorization Act designated the US segment of ISS as a National Lab in order to "...help improve life on Earth, foster relationships among NASA, other Federal agencies, and the private sector, and advance STEM education through utilization of unique ISS Capabilities in microgravity." In the NASA Authorization Act of 2010, Congress directed NASA to select an entity to manage the US National Laboratory. In August 2011, NASA entered into a 10-year agreement with CASIS in order to maximize the use of the ISS US segment as a National Laboratory. Since CASIS began managing the National Lab in 2011, the organization has selected more than 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 ...

Orbital Elements
Orbital elements are the parameters required to uniquely identify a specific orbit. In celestial mechanics these elements are considered in two-body systems using a Kepler orbit. There are many different ways to mathematically describe the same orbit, but certain schemes, each consisting of a set of six parameters, are commonly used in astronomy and orbital mechanics. A real orbit and its elements change over time due to gravitational perturbations by other objects and the effects of general relativity. A Kepler orbit is an idealized, mathematical approximation of the orbit at a particular time. Keplerian elements The traditional orbital elements are the six Keplerian elements, after Johannes Kepler and his laws of planetary motion. When viewed from an inertial frame, two orbiting bodies trace out distinct trajectories. Each of these trajectories has its focus at the common center of mass. When viewed from a non-inertial frame centered on one of the bodies, only the traj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
