Landsat 8 (LDCM) [GD]

Спойлер

On December 23, 2005, the Office of Science and Technology Policy (OSTP) issued a memorandum adjusting the LDCM (Landsat Data Continuity Mission) strategy. NASA was instructed to acquire a single Landsat data continuity mission in the form of a free-flyer spacecraft, which will receive the name Landsat 8. The instrument will collect land surface data similar to that of its Landsat predecessors. The data will be delivered to the U.S. Geological survey who will be responsible for mission operations as well as data collection, archiving, processing and distribution.

The most recent, Landsat 7, was launched in April 1999 and continues to collect data. Because its design lifetime is five years, efforts to implement LDCM have been ongoing to minimize risks to data continuity. Early plans called for NASA to purchase data meeting LDCM specifications from a privately owned and commercially operated satellite system. However, after an evaluation of proposals received from private industry, NASA cancelled the Request-for-Proposals (RFP) in Sept. 2003.

In light of the RFP cancellation, an interagency working group was formed (by the Executive Office of the President) to discuss new plans for Landsat data continuity. These discussions eventually lead to the Aug. 13, 2004 OSTP memorandum which directed federal agencies to place Landsat-type sensors on National Polar-orbiting Operational Environmental Satellite System (NPOESS) platforms.

Following an evaluation of the technical complexity of integrating Landsat-type sensors on the NPOESS platforms, the Dec. 2005 memorandum redirected the Departments of Commerce, Defense, the Interior, and NASA to proceed with the NPOESS program without incorporating a Landsat-type instrument.

The LDCM mandated by the most recent OSTP memorandum will collect and archive data consistent with data from the previous Landsat satellites. Expeditious progress towards he acquisition, launch, and operation of the LDCM is anticipated to minimize any possibility of a gap in Landsat data. Landsat 5 and Landsat 7 are still operational, but Landsat 5 is 22 years old and no redundancy remains for most of its mission critical subsystems. Landsat 7, which was launched in 1999, has lost the use of its instrument Scan Line Corrector and has lost gyro redundancy.

The Operational Land Imager (OLI) is being built by the Ball Aerospace and Technologies Corporation. The Ball contract was awarded in July 2007. OLI improves on past Landsat sensors using a technical approach demonstrated by a sensor flown on NASA's experimental EO-1 satellite. OLI is a push-broom sensor with a four-mirror telescope and 12-bit quantization. OLI will collect data for visible, near infrared, and short wave infrared spectral bands as well as a panchromatic band. It has a five-year design life. The graphic below compares the OLI spectral bands to Landsat 7's ETM+ bands.

The Thermal InfraRed Sensor (TIRS) was added to the LDCM payload to continue thermal imaging and to support emerging applications such as evapotranspiration rate measurements for water management. TIRS is being built by NASA GSFC and it has a three-year design life. The 100 m TIRS data will be registered to the OLI data to create radiometrically, geometrically, and terrain-corrected 12-bit LDCM data products.

In October 2007, a Atlas-5(401) was contracted for the launch.

General Dynamics Advanced Information Systems, now Orbital Sciences Corp., has been selected in April 2008 by NASA to build the spacecraft for the Landsat Data Continuity Mission (LDCM). Under the terms of the $116 million delivery order, Orbital will be responsible for the design and fabrication of the LDCM spacecraft bus, integration of the government furnished instruments, satellite-level testing, on-orbit satellite check-out and continuing on-orbit engineering support. Orbital will also provide a spacecraft/observatory simulator.

Orbital will provide a simple, robust and reliable Landsat spacecraft that allows for rapid integration and testing. The company will use mature, qualified, flight-proven components to reduce development time, shorten integration time and improve performance. Orbital will build the LDCM spacecraft in its state-of-the-art satellite manufacturing facility in Gilbert, Arizona.

Recently my wife and I drove into Roanoke, Va., fr om the south on an old federal highway designated U.S. 221. We had followed it for more than 100 mi. to avoid "high-speed" interstate highways congested with holiday traffic, and to stretch a vacation fr om city life a little longer. For most of the way we enjoyed a bucolic byway winding through photogenic farmland, wh ere stretches of the original roadway clearly were engineered for oxcarts and horses. But as we approached Roanoke—an old railroad city in the southwest corner of the state—the late-fall foliage gave way to the orange warning signs and raw Earth that signify road construction.

Crews are widening Route 221 to accommodate the growing population as Roanoke expands. It's a safe bet that state highway engineers based their decision to spend the money in part on a 40-year-old set of relatively low-resolution images of the area collected by a series of U.S. government Earth-observation satellites that started with launch on July 23, 1972, of the Earth Resources Technology Satellite 1—later renamed Landsat 1.

Every 16 days for most of the past four decades, a Landsat bird has covered the entire globe, generating an unparalleled dataset for tracking changes on the Earth's surface. There are more-capable satellites in terms of resolution, but none offers the steady long-term stream of comparable data that Landsat generates. Given the expense and technical difficulty of flying missions in space, that stream has been a little unsteady in recent years. But a new mission set for a Feb. 11 launch on an Atlas V has the potential to expand the dataset by another decade.

The Landsat Data Continuity Mission (LDCM) spacecraft is in thermal vacuum testing at prime contractor Orbital Sciences Corp.'s Gilbert, Ariz., factory, and on track for a timely launch. The 3,085-kg (6,800-lb.) spacecraft—built around Orbital's LEOStar-3 bus—has a design life of five years, but will carry enough fuel to keep it functioning for 10. Ball Aerospace built its Operational Land Imager to collect data in the visible, near-infrared, short-wavelength infrared and panchromatic bands.

NASA's Goddard Space Flight Center built the spacecraft's Thermal Infrared Sensor (TIRS) using the advanced Quantum Well Infrared Photodetector (QWIP) technology it developed. The TIRS is designed to collect data in two more spectral bands previously covered by a single band on earlier Landsats.

From its polar-orbit perch at an altitude of 705 km (440 mi.), the LDCM will produce "scenes" measuring 185 X 185 km. The medium-resolution format actually is better for mapping changes than the sub-meter resolution available commercially today that can literally make it impossible to see the forest for the trees. Earth's dwindling supply of trees is one resource that Landsat has tracked over the years, according to LDCM chief scientist Jim Irons at Goddard.

"One ecosystem that's particularly susceptible to deforestation is the tropical rain forest, wh ere great swaths of the forest are being converted to agriculture to feed a growing population," he says.

Earth's burgeoning population also contributes to urban sprawl eating its way into farmland. This Landsat 7 image of Houston (photo) collected on Aug. 30, 2000, shows the utility of the dataset for tracking the growth of cities and meeting their infrastructure needs.

When the image of Houston was collected, Landsat 7 was working as advertised, but it has been limping along since its Scan Line Corrector failed on May 31, 2003. The device, which is not backed up by an on-board spare, compensates for the forward movement of the spacecraft in orbit so its adjacent surface scenes line up properly. Since the failure, the satellite data leave about 22% of the ground below its track blank. Until a year ago, Landsat 5 was helping fill in the dataset, but it finally stopped working after 27 years.

The Landsat system is operated by the U.S. Geological Survey (USGS), with NASA in charge of developing and launching the spacecraft. That is what the space agency does best, but the split in responsibility has made it difficult to keep the funding stream flowing against competing priorities.

Now that the two branches of government are getting serious about deficit reduction, that situation is likely to worsen. The budget belt-tightening comes at a time when long-range data are growing in importance as scientists and their political bosses try to gauge just how much of climate change is the result of man-made inputs that can be changed, measurements Irons says Landsat can help make.

The United Launch Alliance booster is scheduled for blastoff in February carrying a remote sensing spacecraft known as the Landsat Data Continuity Mission, or LDCM.

The satellite will continue the 40-year legacy of monitoring the Earth's environment from space through the Landsat series of craft. This latest bird, built by Orbital Sciences Corp., is equipped to obtain medium-resolution multispectral digital images of the global land surface, coastal shallows and coral reefs through the Operational Land Imager and the Thermal Infrared Sensor instruments.

LDCM is a collaboration between NASA and the U.S. Geological Survey to further the Landsat data records that began in 1972 with Landsat 1 and five subsequent follow-on satellites over the decades.

To keep supplying that data archive, LCDM was conceived in 2005 and now stands just two months from launch into a 438-mile polar orbit.

The satellite completed its environmental testing on Nov. 23, undergoing rigorous testing inside a thermal vacuum chamber at the Orbital's facility in Gilbert, Arizona. The tests subjected LDCM to the high heat and low temperature swings it will experience in orbit.

Plans call for the satellite to arrive at Vandenberg on Dec. 19, beginning its own launch site campaign before joining up with the Atlas 5 rocket at the Space Launch Complex 3-East pad a couple of weeks before liftoff.

The rocket's on-pad assembly occurred in early October as the bronze first stage with its RD-180 main engine was erected, followed by the interstage adapter and then the white Centaur with the cryogenic RL10 engine.

On Tuesday, crews retracted the mobile service gantry away from the rocket around 8 a.m. local time and began loading the the supercold liquid oxygen and liquid hydrogen around 10:30 a.m. PST.

Clocks counted all the way to T-minus 0 seconds before cutting off as planned, ending the rehearsal at the pretend 1:40 p.m. local launch time.

Called the Wet Dress Rehearsal, the WDR provides the launch team and mission managers with a realistic run-through of the countdown timeline and decision-making calls. It also gives engineers a chance to uncover any technical problems that need resolved before the actual launch attempt.

The launch is dubbed AV-035 in the Atlas lineup. It will follow the Air Force's X-37B deployment flight planned for next week and the late January mission carrying NASA's Tracking and Data Relay K satellite, both of which will originate from Cape Canaveral, Florida.

Хорошо пошла! На ровном киле и, всё же, достаточно энергично.

А вот съемка неудовлетворительна. Проблемы с удержанием ракеты в кадре на большой высоте, проблемы с фокусировкой, низкое качество картинки с бортовой камеры, а затем постоянные потери сигнала с неё.

Итого, в отличие от запуска, качество его съемки не соответствует стандартам современной американской медиа-индустрии :)

Это выглядит так, а вообще расширение газов идет симметрично во все стороны.

Я предположил бы тоже самое. Но на видео с бортовой камеры очень уж явная струя вбок. Собственно, на заставочном кадре видео в посте Артёма Жарова это видно. На видео полёта на большой высоте тоже факел с боковыми выбросами - там это легче объяснить каким-нить оптическим эффектом или проекцией, но вкупе с предыдущим ...  :oops:

На съёмке с земли такое впечатление что этот кокон круглый, просто по бокам ярче потому что луч зрения идёт вдоль его оболочки.

Есть там выбросы на стыке двух факелов.
Когда потоки расширения газа двух факелов сталкиваются, газ выбрасывает вдоль границы соприкосновения факелов.

Выбросы видно и с земли, начиная с 2:38. Правда, ракета при этом часто вылетает из кадра  :( .
Зато, в 3:05 становится видна линия расположения сопел перпендикулярно линии выбросов.

Стык нескольких факелов бывает у многих, у Титана-2 так и двух, у старого Атласа - почти двух. Только выбросов не видно. :(

Где бы еще найти подходящие рокеткамы на Титане2. В основном короткий участок разделения.
Вот нашел похожие выбросы на Титане2 (с 2:15)

LDCM Status Update for March 8, 2013

All satellite and instruments continue to perform normally. The Mission Operations team completed another round of Attitude Control System calibration maneuvers late last week. In addition, they tested the spacecraft's ability to execute uploaded commands while the satellite is out of range of ground stations, called stored command loads.

 The Mission Operations team also conducted a series of data flow tests that exercised the entire image data transmission and processing functionality of the satellite and ground system using test patterns internally generated by the OLI and TIRS instruments. In these tests, the satellite successfully stored the instrument test pattern data in the onboard Solid State Recorder, and then transmitted that data to the ground when it flew back into range of the ground station. The Data Processing and Archive System (DPAS) at the USGS Earth Resources Observation and Science (EROS) Center in Sioux Falls, S.D., then successfully processed these test patterns as if they were Earth image data. These tests demonstrate the readiness of the entire LDCM satellite and ground system to successfully collect real Earth imagery.

 The OLI and TIRS instruments continue to progress toward coming online. OLI had a successful checkout of its diffuser mechanism, which is part of OLI's calibration system. The main activities this week, however, focused on TIRS. On March 4, the Mission Operations team successfully deployed the TIRS Earth shield from its launch position. The Earth shield is a large panel that blocks heat from Earth from getting onto the TIRS thermal radiators, thus increasing the efficiency of those radiators. Over the past few days the team has checked out the mid-stage heaters, powered up systems, including the Focal Plane Electronics Box, and tested the Scene Select Mirror. On March 6, the TIRS cryocooler was turned on and successfully cooled the sensors to 43 kelvins (-352 F).

For NASA to Build TIRS on Schedule, Every Day Counted
04.22.13


  Fr om the very beginning it was a looming ticking countdown clock to get the Thermal Infrared Sensor (TIRS) instrument ready for the Landsat Data Continuity Mission launch. Even on their very first day, the TIRS development team started a year behind schedule to design, build and test an instrument in three years instead of the more typical four-year development cycle.

 The project began on a tight schedule, but then outside forces intervened. There was the earthquake, hurricane and a near government shut down—but that didn't stop the TIRS team fr om being ready for a successful Landsat launch on February 11. "We received our first image from the TIRS instrument on March 7, and it was just spectacular," said Betsy Forsbacka, TIRS instrument manager at NASA's Goddard Space Flight Center in Greenbelt, Md.

 TIRS came about to help scientists and resource managers monitor water evaporation and transpiration over land surface by measuring radiation emitted in two thermal bands of the electromagnetic spectrum. TIRS operates at a resolution of 100 meters (328 feet), allowing for monitoring fields for agriculture, which is especially important for water managers. The instrument was a relatively late addition to the Landsat mission, which is why there was a tight production schedule.

 "We took three years here at NASA Goddard to take it from initial concept development design, go through all the major reviews to make sure the design was valid, then build and test the instrument, which we did here at NASA Goddard," Forsbacka said. "We delivered the instrument to Orbital Sciences Corp., in Gilbert, Ariz., we integrated onto the spacecraft, and we tested the two instruments and the spacecraft as one large system. In December we delivered the spacecraft with instruments aboard to the launch site and launched on February 11 at Vandenberg Air Force Base in California."

  As the TIRS deputy instrument manager and now instrument manager, the largest unyielding aspect of the project Forsbacka had to manage was time. "For us, it was schedule, schedule, schedule," he said. "Time was the one thing we couldn't make. If we didn't make our delivery date, we would not fly." And then there were the events that couldn't be anticipated. Even with tight project management planning, who could have foreseen an earthquake and hurricane occurring within one week, but that is what happened in August 2011.

 The team was in the midst of thermal vacuum testing, cycling between very hot and very cold temperatures, when the earthquake tremors began. The test team fled the building, and when it was safe to return, the instrument was put into a safe configuration. A couple of days of testing were lost while the team determined if there was any damage. "Actually launch is harsher than the earthquake," Forsbacka commented, "but you don't know that at the time and you wonder what is happening to the instrument."

 Just on the heels of the earthquake, time was lost to planning for Hurricane Irene, which was forecast to arrive only days after the earthquake. The hurricane diverted the schedule by a couple of days for planning essential personnel in the event of a NASA Goddard campus closure and determining what testing would take place and which tests would be put on hold in the event of a severe hurricane. It turns out there was even more unplanned excitement to come for the TIRS team.

 Because TIRS uses Quantum Well Infrared Photodetectors (QWIPs) to detect specific light wavelengths used to measure surface temperature, TIRS had to be outfitted with a cryocooler to keep the QWIP detectors working at the necessary cold temperatures. The cryocooler supplied by Ball Aerospace—the project's largest procurement—was also being developed on a compressed timetable. To keep TIRS on schedule, members of the NASA Goddard TIRS team worked onsite at the Ball Aerospace facility in Boulder, Colo., for a year to facilitate swift decisions.

 "After going through all of the steps of this very complicated procurement, and the design, build, and all the reviews, and getting it through environmental testing, when it came time to ship the cryocooler, it was the weekend of the potential government shutdown in April 2011 [due to a stalled spending deal in Congress]," Forsbacka said. "How do you plan for that?" So the TIRS team worked at a furious pace with Ball Aerospace to get the unit shipped to the NASA Goddard campus as quickly as possible.

 But the TIRS team faced a host of uncertainties about being allowed to report to work due to moratoriums over weekend work. And the cryocooler was in transit to be delivered on a Friday, on the day of the pending shutdown. Forsbacka said the team had to weigh the options. "Do we delay it? With our schedule, we didn't delay anything if we could avoid it. We couldn't get it delivered earlier. If it arrived on time, would anyone be here to receive it?"

 Simple variables such as the delivery truck being delayed due to getting stuck in traffic at various points from Boulder also had to be considered. As it turns out, the cryocooler arrived that Friday night, barely before the midnight cutoff, and just before the team was no longer allowed to work due to the imminent government shutdown.

 Beyond the earthquake, hurricane and threat of a government shutdown, a host of decisions along the way kept the project on track for meeting the launch deadline. At the beginning during the TIRS design, the team focused on meeting requirements rather than seeking perfection. In some cases when a requirement was hard to meet, they asked the scientist if it was a number they absolutely had to have. "In some cases the answer was yes, but in many cases, what you have is good enough," Forsbacka said. "If you don't communicate with your scientists, you can chew up a lot of time."

 Each requirement builds in a worst-case scenario, said Dennis Reuter, the TIRS instrument scientist who authorized any TIRS requirements changes. Sometimes if one requirement meets specifications, another one can be relaxed to still perform the desired task, he said.

 Testing also helped keep TIRS development on track. "We tested much earlier and more often with TIRS than we normally do to meet the accelerated schedule," Reuter said. Instrument subsystems were also developed in parallel so one delay wouldn't hold up the schedule.

 "Schedule is everything, and we couldn't afford to lose even a day," Forsbacka said. "Over three years, if you lose a day, it turns into a week, then a month and then you don't fly." She said it was particularly challenging to get all of the subsystems delivered so the instrument could be assembled for testing. "If there is one subsystem not delivered, it is a showstopper," she said.

 The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey. Once LDCM completes its on-orbit check-out phase in late May, the satellite will be turned over to the USGS and renamed Landsat 8. Data from TIRS and the Operational Land Imager will be processed and added to the Landsat Data Archive at the Earth Resources Observation and Science Center in South Dakota, wh ere it will be distributed for free over the Internet.

LDCM Status Update for May 2, 2013

 All spacecraft and instrument systems continue to perform normally. LDCM continues to collect more than 400 scenes per day and the U.S. Geological Survey Data Processing and Archive System continues to test its ability to process the data flow while waiting for the validation and delivery of on-orbit calibration, which convert raw data into reliable data products.

 During this period, routine calibrations have continued along with Operational Land Imager and Thermal Infrared Sensor instrument imaging. Lunar calibrations were performed during last week's full moon. As of April 24, 2013, the new system for scheduling image collection, the Collection Activity Planning Element is operational. On April 26, 2013, a 1.2-second thruster burn was conducted to maintain the observatory on the proper ground track and counteract drag on the satellite from the atmosphere.

 Then on Saturday, April 27, 2013, LDCM began a 16-day imaging and calibration cycle that is a demonstration of the operational cycle the satellite will follow for the life of the mission. This dress rehearsal will test the entire image planning, collection and processing system at operational rates to verify everything is ready for handover to USGS for routine operations in late May.

Landsat Thermal Sensor Lights Up fr om Volcano's Heat
05.06.13
 
As the Landsat Data Continuity Mission satellite flew over Indonesia's Flores Sea April 29, it captured an image of Paluweh volcano spewing ash into the air. The satellite's Operational Land Imager detected the white cloud of smoke and ash drifting northwest, over the green forests of the island and the blue waters of the tropical sea. The Thermal Infrared Sensor on LDCM picked up even more.

By imaging the heat emanating from the 5-mile-wide volcanic island, TIRS revealed a hot spot at the top of the volcano wh ere lava has been oozing in recent months.

The two LDCM instruments, working together, illustrate a quote from Aristotle: The whole is greater than the sum of its parts, said Betsy Forsbacka, TIRS instrument manager at NASA's Goddard Space Flight Center in Greenbelt, Md.

"Each instrument by itself is magnificent," she said. "When you put them together, with the clues that each give you on what you're seeing on Earth's surface, it's greater than either could do by themselves."

The image of Paluweh also illuminates TIRS' abilities to capture the boundaries between the hot volcanic activity and the cooler volcanic ash without the signal from the hot spot bleeding over into pixels imaging the cooler surrounding areas. TIRS engineers tested and refined the instrument pre-launch to ensure each pixel correctly represents the heat source it images on Earth's surface. Otherwise, Forsbacka said, it would be like shining a flashlight in your eyes -- the bright light can leave you seeing spots and halos wh ere it should be dark. The same effect can occur with detectors. But the contrast is sharp on the Paluweh image.

"We can image the white, representing the very hot lava, and right next to it we image the gray and black from the cooler surrounding ash," Forsbacka said. "It's exciting that we're imaging such diverse thermal activity so well."

The TIRS instrument can also pick up subtle shifts of temperatures, within a 10th of a degree Celsius. And, with two different thermal bands instead of the one band on previous Landsat satellites, LDCM is poised to make it easier for scientists to subtract out the effects of the atmosphere on the signal, obtaining a more accurate temperature of Earth's surface.

Taking Earth's temperature from space can be difficult because the atmosphere gets in the way and alters the thermal signals, Forsbacka said. Scientists looking to estimate surface temperatures with the single thermal band on previous Landsat instruments needed measurements or assumptions about atmospheric conditions.

TIRS has two thermal bands, however. The atmosphere affects each band slightly differently, resulting in one thermal image that's a hair darker than the other. By measuring that difference, and plugging it into algorithms, scientists can better address atmospheric effects and create a more accurate temperature record of the Earth's surface.

The Landsat program is a joint mission of NASA and the U.S. Geological Survey. Once LDCM completes its onboard calibration and check-out phase in late May, the satellite will be handed over to the USGS and renamed Landsat 8. Data from TIRS and OLI will be processed, archived and distributed from the USGS Earth Resources and Observation Science Center in Sioux Falls, S.D., for free over the Internet.

New Animation Marks Arrival of NASA's LDCM Satellite to its Final Orbit
05.15.13

 Have you ever wondered what it might be like to watch the world fly by beneath you fr om space? That dream is elusive for most of us, but the Landsat Data Continuity Mission offers a vicarious flight with a crisper view than our eyes alone would be capable of if we were in space. That view is now available in a new NASA animation.

 After two months of on-orbit testing and calibration, LDCM fired its propulsion system on April 12, 2013, and ascended to its final orbit 438 miles (705 km) above Earth. The animation, made from scenes taken a week later on April 19, allows viewers to fly with the satellite from its final operating orbit.

A 15-minute animation shows 56 Landsat scenes that have been stitched together into a seamless view from Russia to South Africa. The animation was produced at NASA's Goddard Space Flight Center in Greenbelt, Md.

 Orbiting at 16,800 mph (27,000 kph), LDCM made this flight in slightly more than 20 minutes. The animation moves faster, covering 5,665 miles (9,117 kilometers) in nearly 16 minutes. You would have to be moving about 21,930 mph (35,290 kph) to get a similar view — only slightly slower than the Apollo astronauts who entered Earth's orbit from the moon at 25,000 mph (40,200 kph).

 The shorter animation shows a few highlights. Starting in the north, irregular brown fields indicative of a long history of agriculture line the ice-bound Volga River in central Russia. The ice and patches of slightly brown snow reveal a landscape still in winter's grip. Moving southwest, the snow and ice disappear in the next highlighted segment, and the braided channels of the Volga River run freely. Long airport runways mark the location of the city of Akhtubinsk on the northeast side of the river.

Спойлер

The next highlighted segment transitions from green agriculture near Iraq's Mosul Dam Lake on the Tigris River to pale desert around the startling blue Lake Qadisiyah behind Haditha Dam on the Euphrates River. Both regions are part of the Fertile Crescent wh ere agriculture was born, and the rivers still support agriculture today even in the desert. Circular fields line the Euphrates River, the pivot irrigated crops incongruous with the surrounding desert.

 The next sign of life in the desert is the city of Medina, Saudi Arabia, which radiates out in circles from its central white mosque complex. The animation passes over Jeddah before crossing the Red Sea and into Africa.

 Clouds begin to dot the scene over Kenya and Uganda in East Africa in the next segment. Mount Elgon with its broad circular base is a notable landmark on the left side of the scene. Paler green and tan grasslands encroach on dark green forest growing on the sides of the 14,177-foot-high (4,321-meter) ancient volcano. The satellite then crosses over the eastern shore of Africa's largest lake, Lake Victoria. The shallow water is clouded with tan sediment and green plant growth.

 The final highlighted region features the Great Dyke (http://earthobservatory.nasa.gov/IOTD/view.php?id=46341), which runs from northern to central Zimbabwe. This 2.5 billion-year-old formation is an intrusion of igneous rock that pushed into the older rocks that form the core of the African continent. The Great Dyke is rich in minerals and supports an active mining industry.

 The instruments on the Landsat Data Continuity Mission collect data in strips, called paths, as shown in the animation. The strips are divided into smaller chunks or scenes for cataloguing and storage at the U.S. Geological Survey Earth Resources and Observation Science Center (http://eros.usgs.gov/) in Sioux Falls, S.D. The beginning, end and center of the scenes are predetermined to correspond to the scenes collected by Landsat 4, Landsat 5 and Landsat 7, and are catalogued by the path-row system called the Second World-wide Reference System.

 A joint U.S. Geological Survey and NASA mission, LDCM launched on Feb. 11, 2013, and is still in its onboard calibration and checkout phase. The images shown here are considered test data. Once LDCM completes its check-out phase in late May, the satellite will be handed over to the USGS and renamed Landsat 8. After this point, the satellite will be considered operational and data will be available from USGS at no cost over the Internet.

Спутник Landsat 8 под оперативный контроль Геологической службе США

Спутники дистанционного зондирования Земли (например, серии Landsat) помогают ученым изучать и следить за всеми изменениями земли, которые происходят под воздействием естественных или человеческих причин, выявлять критические тенденции и изменения в состоянии природных ресурсов, которые невозможно определить человеческому глазу, пишет Вестник ГЛОНАСС.

30 мая 2013 года НАСА передало оперативное управление над спутником Landsat 8 Геологической службе США (USGS) на церемонии в Су-Фолс, Южная Дакота.

Это событие знаменует начало миссии спутника по расширению уникальной сорокалетней записи данных мониторинга ландшафта Земли из космоса. Спутник Landsat 8 является последним спутником из серии спутников дистанционного зондирования Landsat, которые обеспечивали глобальный мониторинг ландшафта Земли и её изменений с 1972 года. Программа Landsat является результатом совместных усилий НАСА и Геологической службы США.

НАСА запустило спутник Landsat 8 11 февраля в рамках продолжения миссии Landsat Data Continuity Mission (LDCM). С тех пор инженеры и ученые НАСА в сотрудничестве с Геологической службой США вывели спутник на орбиту, выполнили калибровку детекторов и получили тестовые снимки. Теперь спутник получил все сертификаты, предусмотренные миссией, и был передан под оперативный контроль Геологической службе США.

Спутник Landsat 8 проходит вокруг Земли 14 раз в день и, в сочетании со спутником Landsat 7, ученые смогут получать данные с улучшенной частотой с двух спутников.

На борту спутника Landsat 8 находятся два прибора наблюдения, которые, по сравнению со своими предшественниками, существенно улучшают возможность сбора информации, совместимой со снимками, сделанными за 41 год другими спутниками серии Landsat.

Как сообщает imena.ua, командование NASA позволило любому жителю Земли совершенно безвозмездно изучать фотоснимки, сделанные спутником дистанционного зондирования Земли Landsat 8.

Фотографии, сделанные новым спутником Landsat 8, будут выкладываться в свободный доступ. Воспользоваться ими сможет кто угодно – причём совершенно бесплатно. Первые фотоснимки, сделанные «спутником-шпионом» уже можно скачать.

ИТЦ «СКАНЭКС»: снимки со спутника Landsat 8 открыты для свободного доступа

Геологическая служба США предоставила всем заинтересованным пользователям возможность бесплатного доступа к снимкам Земли, получаемым с помощью нового американского спутника ДЗЗ Landsat 8. Снимки находятся в открытом доступе на трех интернет-порталах: EarthExplorer ( http://earthexplorer.usgs.gov ), GloVis ( http://glovis.usgs.gov ) и LandsatLook Viewer ( http://landsatlook.usgs.gov ).

Это исключительно важное для всего сообщества ученых и специалистов, опирающихся в своей деятельности на данные космической съемки, которую на протяжении вот уже более 40 лет ведут спутники системы Landsat, событие произошло после успешного окончания этапа предэксплуатационнных испытаний аппарата Landsat-8, и проведения 30 мая официальной церемонии передачи управления спутником от NASA Геологической службе США.

Landsat 8 был запущен 11 февраля 2013 г., имеет расчетный срок активного существования 5 лет. Однако запас топлива на спутнике позволяет использовать его намного дольше — до 10 лет. На борту Landsat 8 установлены многоканальный сканирующий радиометр OLI (Operational Land Imager) и сканирующий двухканальный ИК-радиометр TIRS (Thermal Infrared Sensor). Радиометр OLI предназначен для ведения космической съемки на основе усовершенствованных технологий с максимальным разрешением 15 м, а ИК-радиометр TIRS — для получения «теплового» изображения земной поверхности с разрешением 100 м.

Ежедневно спутник передает на Землю более 400 снимков, которые обрабатываются в соответствии с единым стандартом, принятым для продуктов системы Landsat, и хранятся в центре Earth Resources Observation and Science Center Геологической службы США в Sioux Falls (шт. Южная Дакота).

Ввиду использования дополнительных спектральных диапазонов на спутнике Landsat 8 файлы изображений имеют увеличенный объем, который в сжатом виде составляет около 1 Гбайт. Также следует иметь виду, что комбинации спектральных поддиапазонов, используемых для получения цветных изображений, у спутника Landsat 8 иные, чем у Landsat 5 и Landsat 7. Так, например, цветное ИК-изображение со спутника Landsat 8 формируется из данных спектральных поддиапазонов 5, 4 и 3, а со спутников Landsat 7 и 5 — из данных поддиапазонов 4, 3 и 2.

Всего, начиная с 2008 года Геологическая служба США предоставила для свободного доступа через Интернет более 11 млн архивных и текущих данных космической съемки с помощью спутников серии Landsat.

Инженерно-технологический центр «СКАНЭКС» оказывает услуги по предоставлению данных со спутников Landsat 5 и Landsat 7 как из внутреннего архива центра, так и из глобального архива Геологической службы США. Кроме того, «СКАНЭКС» планирует осуществлять прием данных с аппарата Landsat 8 с помощью собственной сети станций «УниСкан» в России. В настоящее время проводятся испытания и отладка получения и обработки данных. При организации приема данных Landsat 8 на сеть станций ИТЦ «СКАНЭКС» космоснимки будут доступны в оперативном режиме для пользователей из России, ближнего и дальнего зарубежья.

Кроме того данные Landsat 8 планируется широко использовать в новой системе космического общественного мониторинга «Космический патруль». Данная система является общественно значимой инициативой и направлена на формирование качественно новой культуры взаимодействия власти и гражданского общества; комплексное социально-экономическое развитие России и совершенствование работы в области экологии и охраны природы, образования, разработки и внедрения инновационных технологий, снижения уровня коррупции в государственных и коммерческих структурах, повышения степени самосознательности граждан.
