what modern technology helps us to study the earths physical features
NASA uses cutting-edge applied science from satellite sensors and airborne instruments to super computers and visualization methods to meliorate understand our home planet and help amend lives. We're developing the next generation of emerging technologies to be able to answer questions about our changing world.
1—Small Satellites, Big Science
CubeSats are small. Very modest. Then minor, in fact, they tin can be held in the palm of your hand. They range in size from a pint of ice foam, to a loaf of staff of life, to a large cereal box. Inside each of these small satellites you'll observe electronics, instrument components, and radios for communication simply like in other satellites. Simply these tiny satellites are dissimilar and NASA's Earth Science Division is using them to advance what is possible.
NASA is continually developing new technologies to improve our knowledge about Earth – technologies that are smaller than ever before, components that could amend our measurements, on-board data processing systems that streamline data retrievals, or new methods for gathering observations. Each new engineering science is thoroughly tested in a lab, sometimes on aircraft, or even at remote sites beyond the world. Simply the space surround is different than Earth. To know how something is going to operate in infinite, testing in space is the best option.
Sending something unproven to orbit has traditionally been a risky endeavor, but CubeSats have helped to change that. The atomic satellites typically take less than two years to build. Virtually American rocket launches contain CubeSats every bit a secondary payload, profoundly reducing the cost of launching. These hitchhikers can be deployed from the rocket or can exist sent to the International Space Station and later deployed from there.
Because of the quick evolution time and like shooting fish in a barrel access to space, CubeSats take become the perfect platform for demonstrating how a new technological advancement will perform in orbit. All of this helps to ensure that NASA's Earth-observing missions will reliably be able to collect cutting-edge data.
two—See CubeRRT; Information technology'due south Hither to Get Rid of the Noise
When the validation mission for a satellite the size of a cereal box launches in May, information technology volition space test a pocket-sized component designed to detect and filter radio frequency interference (RFI), eventually benefitting futurity satellite missions.
Radio frequency interference (RFI) is everywhere; sources include cellphones, radio and TV transmissions, satellite broadcasts and other sources. Yous probably recognize it as that annoying static when you can't seem to go your favorite radio station to come in clearly because another station is nearby on the dial.
The same interference that causes radio static as well affects the quality of data that instruments like microwave radiometers collect. Every bit the number of RFI-causing devices increases globally, NASA'south satellite instruments – specifically, microwave radiometers that assemble data on soil moisture, meteorology, climate and more – will be more challenged in collecting high-quality information.
That's where CubeSat Radiometer Radio frequency interference Technology (CubeRRT) comes in. The minor satellite will be carrying a new technology to detect and filter whatever RFI the satellite encounters in real-time from infinite. This will reduce the amount of data that needs to be transmitted back to Earth – increasing the quality of important weather and climate measurements.
3—32 Current of air Measurements Per 2d
Last year, NASA'south Cyclone Global Navigation Satellite System (CYGNSS) kept an unprecedented spotter over the hurricane season from low-Earth orbit. The constellation of eight microsatellite spacecraft, built and operated by Southwest Inquiry Found (SwRI), gathers data to aid the atmospheric condition forecasting community improve existing storm prediction models.
Flying in formation, the eight CYGNSS small satellites continuously monitor surface winds over the oceans across Earth's tropical hurricane-belt latitudes. Each satellite is capable of capturing 4 wind measurements per second, adding as many every bit 32 air current measurements per second for the unabridged constellation.
Radar from conditions satellites has difficulty measuring through heavy clouds virtually the center of a hurricane. CYGNSS, still, fills that crucial gap. The microsatellites work past receiving GPS satellite signals, which can penetrate even the heaviest cloud cover straight into the eyewall to gather information about a storm's intense inner core.
The GPS and microsatellite technology used for CYGNSS has enabled observations from earlier and after flooding from Hurricane Harvey, the overpass of Hurricane Maria, and virtually-surface soil moisture over the Amazon Basin.
4—Supercomputers for Science
Visualizations like this one, showing the 2015-16 El Niño, are made possible by combining data from NASA spacecraft and the computing power able to procedure vast amounts of data.
Typical desktop computers have iv to 8 processor cores; the supercomputer used to process this visualization has 90,000 processor cores. This Discover supercomputer, part of the NASA Center for Climate Simulation at Goddard Infinite Flight Center, is currently capable of 3.5 petaflops (that's 3,500 trillion) of operations a 2nd.
Notice is expanding to 108,000 processor cores. With the upgrades, Notice will have a combined height performance of over 5 petaflops per second. These improvements volition not only allow researchers to continue up with the increasing amount of Earth observing data to better understand our dynamic planet, merely NASA visualizers will also have the data necessary to convey the scientific discipline.
5—Teaching Machines to Learn
Researchers have "taught" a computer to assist them better understand the impacts of wood fires. A team from NASA's Ames Enquiry Center, in California's Silicon Valley, and the Academy of Minnesota is applying bogus intelligence (AI) techniques to satellite data to map the effects of tropical forest fires — similar the 2015 Sumatra fire in this photograph.
Using machine learning, an arroyo to AI, the researchers developed a method that trains a computer to distinguish burned from unburned pixels in NASA satellite imagery of tropical forests. With that information, it can produce a map of fire activity.
half dozen—Unlocking the Mysteries of Ocean Surface Currents and Winds
NASA scientists are hard at piece of work trying to unlock mysteries of Earth's ocean surface currents and winds using a new radar instrument called DopplerScatt.
Ocean currents and winds class a never-catastrophe feedback loop: winds blow over the bounding main'south surface, creating currents. At the same fourth dimension, the hot or common cold water in these currents influences the wind'south speed. Agreement the relationship between the two phenomena is crucial to understanding Earth'south changing climate. Gathering data on this interaction tin also help people track oil spills, plan shipping routes and understand ocean productivity in relation to fisheries.
DopplerScatt, adult by NASA'south Jet Propulsion Laboratory in Pasadena, California, provides a new capability to measure out both winds and currents simultaneously.
Flying aboard a B200 Rex Air aircraft, DopplerScatt is a spinning radar that "pings" the ocean's surface, assuasive it to take measurements from multiple directions at once.
Like a highway patrol officeholder's speed gun, the DopplerScatt instrument calculates the Doppler effect of a radar signal bouncing off an object. Equally that object moves closer or further away, it detects these changes and figures out its speed and trajectory. Those measurements are combined with data from a scatterometer, which detects the reflection of the radar bespeak from the ocean's surface. The more than "scattering" the radar observes, the rougher the waves. From the roughness and orientation of the waves, current of air speed and direction can be calculated.
7—Bringing Ecosystems Into Focus
Sometimes information technology takes a new engineering to solve an old problem. A NASA photographic camera carrying new software peers beneath waves to bring ecosystems into focus. Fluid Cam, the imaging musical instrument that carries the new lensing software, is small plenty to fly on a drone.
Fluid lensing strips away distortion from ocean waves and other movement to amend show coral reefs beneath the surface. Anytime, this technique could be flown on an orbiting satellite to gather image data on the world's reefs.
Somewhen the same technology could be used to bring other worlds into focus.
