Спутники DigitalGlobe переходят под прямой контроль Пентагона

Коммерческая по форме американская компания, готовящаяся стать мировым монополистом на рынке сверхдетальных ДДЗ, становится военной по сути и переходит в режим прямого обслуживания ВВС США.

Компания DigitalGlobe заключила с ВВС США договор, предусматривающий модернизацию мобильных наземных приёмных станций Eagle Vision ВВС США. Работы будут вестись совместно с компаниями MDA и Orbital Logic; первый модернизированный терминал планируется передать военным в середине 2013 года.

За этим формальным поводом скрывается неординарное событие - группировка коммерческих спутников может в любой момент перейти под прямой контроль Пентагона.

Модернизация станций Eagle Vision позволит войскам прямо на передовой получать доступ не только к архиву данных спутниковой съёмки сверхвысокого (и даже более высокого, нежели доступно на мировом рынке) разрешения - в том числе восьмиканальным - и, возможно, оплаченных их противником. Прямо оговорена возможность перевода спутников под прямое управление военных - те получат возможность через EagleVision самостоятельно формировать задания на съёмку для всех спутников группировки, отодвигая на иной план заказчиков коммерческих.

А поскольку в скором будущем, с анонсированным уже объединением с GeoEye компания DigitalGlobe обречена стать абсолютным мировым монополистом в области высокодетальных и высокоточных ДДЗ, фактическим обладателем права монопольного доступа к её ресурсам становится Пентагон, способный в нужный момент воспользоваться этими ресурсами в своих, и только в своих, целях.

С ожидаемым в начале 2013 года объединением с GeoEye орбитальная группировка компании DigitalGlobe, ныне насчитывающая три спутника, увеличится до пяти, а в скором будущем - и до шести аппаратов. Спутники этой группировки позволяют получать изображения земной поверхности с наилучшей метрической точностью, наивысшим пространственным (до 0,4 м/пиксель) и наилучшим спектральным (до восьми каналов в видимом и ИК-диапазонах) разрешениями. Объединение воедино двух группировок систематизирует и упорядочит их использование, повысит производительность, позволит решать принципиально новые классы задач, а также даст возможность сполна воспользоваться монопольным положением компании на мировом рынке не только в её интересах, но и в интересах Пентагона.

Стражи Земли: спутник Landsat 5 завершает свою миссию

Геологическая служба США (United States Geological Survey, USGS) заявила о завершении миссии спутника «Landsat 5». Старичок был запущен в космос еще в 1984 году и рассчитан на три года эксплуатации.

Его пребывание в космосе мягко сказать затянулось. За немалый промежуток времени, почти 30 лет, спутник облетел Землю около 150 тысяч раз и передал около 2,5 миллиона различных фотографий.
«Все крупные события начиная с 1984 года, которые оставили на Земле большой отпечаток, к примеру, ураган, цунами, пожар, вырубка леса или разлив нефти были запечатлены спутником Landsat 5», - заявила Марсия МакНатт (Marcia McNutt), директор USGS.
На данный момент за нашей планетой наблюдает спутник Landsat 7, а в феврале 2013 года USGS планирует запустить Landsat 8. Также предлагаем Вам ознакомиться с интересным видео, сделанным специалистами Google на основе снимков спутников Landsat.

Самый старый действующий спутник Landsat 5 будет выведен из эксплуатации

Геологическая служба США (US Geological Survey, USGS) намерена в скором времени вывести из эксплуатации наблюдательный спутник Landsat 5. Этот аппарат был запущен в 1984 году и был рассчитан на срок эксплуатации 3 года, но до сих пор остается в рабочем состоянии на орбите Земли. Таким образом, он стал наиболее долго эксплуатируемым спутником, остающимся на орбите.
С момента запуска спутник Landsat 5 совершил около 150 тыс витков вокруг Земли и передал около 2,5 млн изображений. По словам директора USGS Марсиа МакНатт (Marcia McNutt), все крупные события начиная с 1984 года, которые оставили на Земле большой отпечаток, чем размеры футбольного поля, были запечатлены спутником Landsat 5. К таким событиям относятся ураганы, цунами, пожары, вырубка леса, разлив нефти. За свою почти 30-летнюю историю своего существования спутник Landsat 5 несколько раз выходил из строя, но его удавалось восстановить. Однако 21 декабря стало известно, что на нем произошла поломка гироскопа, не поддающаяся ремонту. Потому и было принято решение вывести спутник из эксплуатации в ближайшие несколько месяцев.

В настоящий момент наблюдение за Землей осуществляет еще одни спутник - Landsat 7. Он был запущен в 1999 году. А в феврале 2013 года USGS планирует вывести на орбиту аппарат Landsat 8.

Mission Accomplished for Landsat 5
       Released: 12/21/2012 10:55:27 AM

Today the U.S. Geological Survey announced that Landsat 5 will be decommissioned over the coming months, bringing to a close the longest-operating Earth observing satellite mission in history.  By any measure, the Landsat 5 mission has been an extraordinary success, providing unprecedented contributions to the global record of land change. The USGS has brought the aging satellite back from the brink of failure on several occasions, but the recent failure of a gyroscope has left no option but to end the mission. 
Now in its 29th year of orbiting the planet, Landsat 5 has long outlived its original three-year design life. Developed by NASA and launched in 1984, Landsat 5 has orbited the planet over 150,000 times while transmitting over 2.5 million images of land surface conditions around the world.  
"This is the end of an era for a remarkable satellite, and the fact that it flew for almost three decades is a testament to the NASA engineers and the USGS team who launched it and kept it flying well beyond its expected lifetime," stated Anne Castle, Department of the Interior Assistant Secretary for Water and Science. "The Landsat program is the 'gold standard" of satellite observation, providing an invaluable public record of our planet that helps us tackle critical land, water, and environmental issues." 
 "Any major event since 1984 that left a mark on this Earth larger than a football field was likely recorded by Landsat 5, whether it was a hurricane, a tsunami, a wildfire, deforestation, or an oil spill," said USGS Director Marcia McNutt. "We look forward to a long and productive continuation of the Landsat program, but it is unlikely there will ever be another satellite that matches the outstanding longevity of Landsat 5." 
For more than a quarter of a century, Landsat 5 has observed our changing planet. It has recorded the impact of natural hazards, climate variability and change, land use practices, development and urbanization, ecosystem evolution, increasing demand for water and energy resources, and changing agricultural demands worldwide. Vital observations of the Mount Saint Helens eruption, Antarctica, the Kuwaiti oil fires, the Chernobyl disaster, rainforest depletion, major wildfires and floods, urban growth, global crop production, and ice shelf expansion and retreat have helped increase our understanding and awareness of the impact of humans on the land. 
The USGS Flight Operations Team recently began the process required to safely lower Landsat 5 from its operational orbit. The first series of maneuvers is expected to occur next month.   
With Landsat 5's decommissioning, Landsat 7, which was launched in 1999 and has also outlived its five-year design life, will continue to provide information, although an instrument anomaly reduces the amount of data it collects.  The next mission, Landsat 8 — also called the Landsat Data Continuity Mission — is scheduled for launch by NASA in February 2013.   
The natural resource management and development challenges that the Nation has faced since the beginning of the Landsat program have not diminished; they've only accelerated.  Landsat, and the many applications that it has spawned, will be even more critical in the future to keep pace with these challenges.  The Department of the Interior and NASA are working closely with the Administration on options for long-term continuity of the Landsat data stream.
Since 2008, when the USGS made the Landsat archive accessible to on-line users at no cost, nearly 10 million images, each covering over 12,000 square miles, have been downloaded in 190 countries.

One commercial Earth-imager deferred in favor of another

As anticipated, a commercial Earth-imaging satellite making its way through final testing for a planned springtime launch atop an Atlas 5 rocket from California instead will enter prolonged storage after a major merger in the industry.
 
Previous competitors GeoEye of Virginia and DigitalGlobe of Colorado operated independent fleets of sharp-eyed satellites to collect high-resolution images of the Earth's surface. But under the merger that closed Jan. 30, the two rivals will have a combined constellation of five Earth observation satellites and a broad suite of high-value geospatial production and analytic services.

The two companies also have two state-of-the-art satellites under construction, GeoEye 2 originally slated for launching this spring and WorldView 3 following in 2014 aboard Atlas 5 rockets from Vandenberg Air Force Base, California.

Under the revised plan announced Monday, the GeoEye 2 spacecraft will see its launch deferred at least a few years while WorldView 3 progresses as scheduled towards liftoff in the middle of next year to support the firm's EnhancedView contract to supply images to the U.S. government and the National Geospatial-Intelligence Agency.

WorldView 3 was sel ected to proceed forward because it will have the capability to provide imagery in multiple short-wave infrared bands that can penetrate haze, fog, dust, smoke and other air-born particulates, officials said.

"After careful consideration and discussions with our largest customer and others, we have determined that launching WorldView 3 and preserving GeoEye 2 as a ground spare will best meet the collective needs of customers and shareowners alike," said Jeffrey R. Tarr, president and chief executive officer of the merged company named DigitalGlobe.

"This plan reduces our risk profile and capital footprint, while giving our customers access to the most advanced earth observation capabilities available commercially. Furthermore, as we move forward, if demand exceeds our expectations, we will be well positioned to quickly expand our constellation. GeoEye 2 and WorldView 3 are extraordinary satellites, and I want to thank all of our team members and partners for their continued efforts toward their completion."

Ball Aerospace is building WorldView 3, which is designed to collect imagery at 31-centimeter panchromatic resolution, 1.24-meter multispectral resolution in 8 spectral bands and 3.7-meter short-wave infrared resolution in an additional 8 spectral bands.

Flying at altitude of 617 km (383 miles), the satellite will be capable of collecting up to 680,000 square km per day, bringing the collection capacity of the DigitalGlobe constellation to over 4.2 million square km per day.

Lockheed Martin is building GeoEye 2 to the specs of capturing panchromatic imagery at 0.34-meter resolution from an altitude of 681 km (423 miles).

Officials said the satellite, which has been assembled and is undergoing environmental testing to simulate the in-space conditions it will face, will be postured to launch when a replacement is needed for the constellation or if customer demands require it sooner.

The delayed deployment now gives United Launch Alliance a combined dozen Atlas and Delta flights this year. The first mission was completed successfully last week and the next is planned for Monday, Feb. 11 fr om Vandenberg.

ESA picks "Biomass" as new satellite mission to explore precious resources of Earth

2013-05-08 06:12:44

PARIS, May 7 (Xinhua) -- A new Earth Explorer mission "Biomass" is set to become the next in a series of satellites developed to further people's understanding of the Earth, the European Space Agency (ESA) said Tuesday.

This innovative satellite, which was sel ected by the ESA's Earth Observation Programme Board to be the seventh Earth Explorer mission, aims to map and monitor one of Earth's most precious resources, the ESA said in a statement.

"Biomass is an innovative new addition to the Earth Explorer satellite series," said Volker Liebig, director of the ESA's Earth Observation Programmes. It will play an important role in quantifying forest biomass, information necessary to better understand the carbon cycle.

"The satellite will be designed to provide, for the first time fr om space, P-band radar measurements that are optimised to determine the amount of biomass and carbon stored in the world's forests with greater accuracy than ever before," the world leading space agency added.

Biomass also has the potential to evolve into an operational system, providing long-term monitoring of forests, one of the Earth's most important natural resources, according to the ESA.

The launch of the mission is foreseen for 2020, it noted.

The Earth Explorers are a series of satellites developed to further people's understanding of the Earth.

Three missions currently in orbit are providing new insight into the Earth's cryosphere, gravity and soil moisture and ocean salinity. Future missions will provide new information on the magnetic field, wind and how clouds and aerosols affect the radiation budget.

June 5, 2013 – Final command sent to Landsat 5

For over 29 years, commands have been sent to Landsat 5 for acquisitions, orbital maneuvers, to fix problems, and even to avoid space junk. Today at 11:34 EDT, the final command was sent to Landsat 5, to turn her solar array away from the sun, essentially ending further power to the onboard computer. She is out of fuel and will reenter and burn up in Earth's atmosphere in around 21 years. Landsat 5 was certainly crotchety at times, but her longevity is now legend, and we'll miss her.

19 June 2013
ESA's new Biomass mission and the numerous accomplishments fr om the existing Earth Explorer satellites came into focus today at the Paris Air and Space Show.

The recently selected Biomass satellite will measure the amount of biomass and carbon stored in the world's forests with greater accuracy than ever before. This information, which is poorly known in the tropics, is essential to our understanding of the role of forests in Earth's carbon cycle and in climate change.

During a press briefing at the Paris Air and Space Show, Biomass Principal Investigator Shaun Quegan spoke about how the mission will address urgent scientific, political and societal issues.

"Carbon dioxide absorption by forests plays a crucial role in understanding climate change, but is very little known. Biomass will be the first mission to provide detailed information on this.

"Forests also play an important environmental role by preventing erosion, reducing avalanche risk and by acting as a gigantic filter for ground water – another suite of factors wh ere the Biomass satellite will deliver crucial information."

The innovative technique that will measure biomass can also be used to measure glacier and ice-sheet velocities, subsurface geology and the ionosphere.

Biomass will be the seventh Earth Explorer, a series of satellites developed to further our understanding of Earth.

Volker Liebig, Director of ESA's Earth Observation Programmes, introduced the ambitious objectives of the other Earth Explorers. The three missions already in orbit, CryoSat, GOCE and SMOS, are providing new insight into Earth's cryosphere, gravity and soil moisture and ocean salinity, respectively.

Johnny Johannessen, Director General of the Nansen Environmental and Remote Sensing Center and former Chairman of ESA's Science Advisory Committee, outlined some of the missions' numerous achievements and unexpected results. These included GOCE's detection of the 2011 Japan earthquake, tracking hurricanes with SMOS and CryoSat's profiling of inland water targets.

Future Earth Explorer missions will provide new information on the magnetic field, wind and how clouds and aerosols affect the radiation budget.
