It takes 16 days for the swaths to overlap enough to image the whole Earth.Previous Landsat sensors swept back and forth across the swath like a whisk broom to collect data. The sensor looked at a calibration source at the end of every row, which means that measurements were consistent from orbit to orbit. But this sensor design requires fast-moving parts, which are more likely to break.—and which did on Landsat 7.In contrast, the instruments on Landsat 8 view across the entire swath at once, building strips of data like a pushbroom. This approach requires no moving parts and gives the sensor detectors greater dwell time. The pushbroom instrument is smaller and lighter than previous whisk broom instruments, but its calibration is much more complex given the large number of detectors.“It was a natural step to evolve to a pushbroom sensor. The technology was proven on other satellites, and we knew we could get better accuracy. The pushbroom has no moving parts. It is a newer and more reliable technology.” explains Terry Arvidson, senior project engineer.For more information on the future of Landsat instruments, read https://landsat.gsfc.nasa.gov/landsat-9/instruments/. || ", "hits": 391 }, { "id": 12339, "url": "https://svs.gsfc.nasa.gov/12339/", "result_type": "Animation", "release_date": "2016-08-17T02:00:00-04:00", "title": "OSIRIS-REx L-14 Press Briefing Graphics", "description": "OSIRIS-REx is on a mission to study asteroid Bennu and return a sample to Earth.

The evidence comes from a specific type of X-ray pattern — nicknamed a \"heartbeat\" because of its resemblance to an electrocardiogram — that until now has been recorded in only one other black hole system. Named IGR J17091-3624 after the astronomical coordinates of its sky position, the binary system pairs a normal star with a black hole that may weigh less than three times the sun's mass, near the theoretical boundary where black-hole status first becomes possible. Flare-ups occur when gas from the normal star streams toward the black hole and forms a disk around it. Friction within the disk heats the gas to millions of degrees, which is hot enough to radiate X-rays.The record-holder for ubiquitous X-ray variability is another black hole binary named GRS 1915+105. This system is unique in displaying more than a dozen highly structured patterns — typically lasting between seconds and hours — that scientists distinguish by Greek-letter names. Seven of these patterns are now seen in IGR J17091, including the so-called rho-class oscillations that astronomers describe them as the \"heartbeat\" of black hole systems.It's thought that strong magnetic fields near the black hole's event horizon eject some of the gas into dual, oppositely directed jets that blast outward at nearly the speed of light. The peak of its heartbeat emission corresponds to the emergence of the jet. Changes in the X-ray spectrum observed by RXTE during each beat in GRS 1915 reveal that the innermost region of the disk emits enough radiation to push back the gas, creating a strong outward wind that staunches the inward flow, briefly starving the black hole and shutting down the jet. This corresponds to the faintest emission. Eventually the inner disk gets so bright and so hot that it essentially disintegrates and plunges toward the black hole, re-establishing the jet and beginning the cycle anew. In GRS 1915+105, which at 14 solar masses is by for the more massive of the two, this cycle can take as little as 40 seconds. In IGR J17091, the emission can be 20 times fainter than GRS 1915, and the heartbeat cycle can occur up to eight times faster.Download the animations here. || ", "hits": 71 }, { "id": 10876, "url": "https://svs.gsfc.nasa.gov/10876/", "result_type": "Produced Video", "release_date": "2011-12-15T10:00:00-05:00", "title": "Black Hole Pulse Animation", "description": "Animations associated with the RXTE Black Hole 'Heartbeat' release.View the short video using these animations here. || ", "hits": 184 }, { "id": 10812, "url": "https://svs.gsfc.nasa.gov/10812/", "result_type": "Produced Video", "release_date": "2011-10-05T15:00:00-04:00", "title": "Landsat 8 (aka LDCM) Spacecraft Animations and Still Images", "description": "Landsat 8 (formerly known as LDCM, the Landsat Data Continuity Mission), a collaboration between NASA and the U.S. Geological Survey, will provide moderate-resolution (15 meter - 100 meter, depending on spectral frequency) measurements of the Earth's terrestrial and polar regions in the visible, near-infrared, short wave infrared, and thermal infrared.

Each lobe is 25,000 light-years tall and the whole structure may be only a few million years old. Are the bubbles remnants of a massive burst of star formation? Leftovers from an eruption by the supermassive black hole at our galaxy's center? Or or did these forces work in tandem to produce them? Scientists aren't sure yet.For more content related to these bubbles, go to#10688. || ", "hits": 70 }, { "id": 10655, "url": "https://svs.gsfc.nasa.gov/10655/", "result_type": "Produced Video", "release_date": "2010-09-27T00:00:00-04:00", "title": "NASA Hurricane Hunters", "description": "During the 2010 hurricane season, NASA deployed its piloted DC-8 and WB-57, and unmanned Global Hawk aircraft in a massive effort to collect as much data as possible, arming hurricane researchers with the information needed to predict the growth and intensification of hurricanes. || ", "hits": 25 }, { "id": 10637, "url": "https://svs.gsfc.nasa.gov/10637/", "result_type": "Produced Video", "release_date": "2010-09-01T08:00:00-04:00", "title": "GRIP Video File", "description": "The GRIP 2010 hurricane mission is in full force. During this year's Atlantic hurricane season, researchers will be able to \"see\" below the cloud-tops and uncover what is happening in the internal structure of the storm through the use of powerful instruments onboard the DC-8, WB-57, and Global Hawk aircraft. This will allow scientists to better understand what is required to kick-start a tropical depression into a hurricane. The NASA aircraft will be deployed from Florida (DC-8), Texas (WB-57) and California (Global Hawk) and will fly at varying altitudes over tropical storms in an attempt to capture them at different stages of development.For complete transcript, click here. || G2010-094_GRIP_VF__MASTER_appletv.01352_print.jpg (1024x576) [103.6 KB] || G2010-094_GRIP_VF__MASTER_appletv_web.png (320x180) [258.1 KB] || G2010-094_GRIP_VF__MASTER_appletv_thm.png (80x40) [16.7 KB] || G2010-094_GRIP_VF__MASTER_appletv.m4v (960x540) [218.4 MB] || G2010-094_GRIP_VF_MASTER_prores.mov (1280x720) [7.9 GB] || G2010-094_GRIP_VF_MASTER.wmv (1280x720) [191.6 MB] || G2010-094_GRIP_VF_MASTER_youtube_hq.mov (1280x720) [238.1 MB] || G2010-094_GRIP_VF__MASTER_appletv.webmhd.webm (960x540) [63.4 MB] || G2010-094_GRIP_VF_MASTER_ipod_lg.m4v (640x360) [75.2 MB] || G2010-094_GRIP_VF_MASTER_portal.mov (640x360) [161.9 MB] || G2010-094_GRIP_VF_MASTER_nasacast.mp4 (320x240) [34.8 MB] || G2010-094_GRIP_VF_MASTER_SVS.mpg (512x288) [70.2 MB] || ", "hits": 19 } ] }
