SSC... An 11-Year Celebration

Eleven years have now passed since the Swedish satellite...
...Odin was launched from Svobodny, Russia. After 60,000 orbits, the satellite still delivers valuable scientific data. Odin was designed and manufactured by SSC in a multilateral project, including Canada, Finland and France, between 1991 and 2000. SSC was also responsible for the satellite operations until SSC's Space Systems Division was divested to OHB in 2011. SSC's satellite station at Esrange is still used for communication with the satellite.

Odin was designed for both astronomy and aeronomy studies. In the latest years, it has been used solely for atmospheric research, observing the changes of the ozone layer as well as processes related to gobal warming. The satellite was designed for a nominal lifetime of two years in orbit, but is still working well and delivers daily amounts of valuable data to the scientific community. Through the years, data from Odin has resulted in numerous doctoral theses.

USGS... Landsat 5 Operations Ops Hold Extended

Landsat 5 Earth imaging operations have been suspended for an additional 90 days while the....
.....U.S. Geological Survey Flight Operations Team (FOT) continues to investigate options for the resumption of imaging. Landsat 5 imaging was halted in November 2011 when an electronic component vital to transmission of the satellite's Thematic Mapper (TM) data began showing signs of imminent failure. Following an unsuccessful attempt to recover the backup electronic component, the FOT is exploring potential changes to operational procedures for the primary component.

"The challenge of attempting to recover operations of malfunctioning, 3-decade-old components in an unmanned satellite orbiting more than 400 miles above Earth is daunting to say the least," said USGS Director Marcia McNutt. "Regardless of whether any additional data is collected, Landsat 5 has already exceeded all expectations for longevity." Should no significant improvement in transmitting TM data be realized, a very limited amount of transmission life would remain. In that case, TM imaging will be prioritized to collect growing season imagery over the Northern Hemisphere.

Meanwhile, the USGS is researching the prospect of recovering the secondary imaging instrument on Landsat 5, the Multispectral Scanner (MSS), which was turned off many years ago. The MSS instrument collects imagery in four spectral bands at 79-meter resolution and uses a different data transmission scheme than the TM instrument. MSS data would provide some data continuity in the event TM data could no longer be transmitted. However, the current condition of the instrument is unknown and the reception and ground processing capabilities for its data would have to be reconstituted.

As it approaches the 28th anniversary of its launch, Landsat 5 is in a safe state while the USGS is doing everything it can to restore imaging operations. Should neither the restoration of TM data transmissions nor the revival of the MSS instrument succeed, the USGS will proceed to decommission the satellite. The FOT is now developing the procedures required to turn off all systems and safely lower the orbit of Landsat 5, should this step prove necessary.

The USGS-operated Landsat 7 remains in orbit collecting global imagery. Since its launch in 1999 with a 5-year design life, Landsat 7 has experienced an instrument anomaly which reduces the amount of data collected per image. Landsat 8, currently called the Landsat Data Continuity Mission, is now scheduled to be launched in January 2013. The Landsat Program is a series of Earth observing satellite missions jointly managed by the U.S. Geological Survey and NASA. Landsat satellites have been consistently gathering data about our planet since 1972. They continue to improve and expand this unparalleled record of Earth's changing landscapes for the benefit of all.

Thales Alenia Space... Set To Build The 3G Version

Thales Alenia Space has signed a contract with the European Space Agency (ESA) to supply....
....Meteosat Third Generation (MTG) satellites for Eumetsat, the European meteorological satellite organization. Thales Alenia Space is prime contractor for this large-scale program, in partnership with German company OHB. The first phase of this program started in November 2010, and has now been definitively approved by the ESA industrial policy committee.

Thales Alenia Space has built Meteosat satellites since the beginning of geostationary weather forecasting systems in Europe, more than 30 years ago. ESA and Eumetsat issued a request for proposals for the development of the third-generation satellites, and Thales Alenia Space was able to propose industrial partnerships meeting ESA's geographical return rule, from both the qualitative and quantitative standpoints. The Thales Alenia Space's proposal not only delivers the performance expected by users, but also underpins the development of innovative solutions and ensures competitive prices. The development of the satellites and their instruments started in November 2010, resulting in an initial consolidation of the system definition, and a selection by competitive bidding of the industrial team in charge of producing components and subassemblies for the different modules. As of early 2012, most of the industrial partners have now been selected. The program is now on track and in 2012, the detailed design will be validated by Preliminary Design Reviews (PDR) for the system, instruments and platform.

The MTG program comprises six satellites: four MTG-1 imaging and two MTG-S sounding satellites. The imaging satellites will deliver one image every ten minutes, and will operate in 16 bandwidths. They will be used to determine temperature and humidity profiles in a vertical section of the atmosphere. In addition, the satellites will carry an extra ultraviolet sounding instrument, within the scope of Europe's GMES program (Global Monitoring for the Environment and Security), to analyze the constituent gases in the atmosphere. With enhanced spatial resolution, continuous observation capability, and complementary imaging/sounding data, the Meteosat Third Generation satellites will considerably improve the quality and reliability of meteorological models and weather forecasts.

The three satellites that make up ESA's Swarm magnetic field mission were presented to the media on 17 February 2012 at the IABG centre in Ottobrunn in Germany. Following a demanding testing programme, the satellites were displayed in the cleanroom before they are shipped to Russia for their July launch.

Swarm will identify and measure the magnetic signals that stem from Earth's core, mantle, crust, oceans, ionosphere and magnetosphere – all of which create the magnetic field that protects our planet. This information will provide insight into processes occurring deep inside the planet and yield a better understanding of the near-Earth electromagnetic environment and the impact solar wind has on Earth.

Ball Aerospace... Imager Is Shipped

Ball Aerospace & Technologies Corp. has shipped the Global Precipitation Measurement (GPM) Microwave Imager (GMI)...
...to Goddard Space Flight Center for integration with NASA's Global Precipitation Measurement Mission spacecraft. The GMI instrument will play an essential role in the worldwide measurement of precipitation and the Earth's environmental forecasting when it launches aboard the GPM space-borne Core Observatory in 2014. The GPM mission is a joint effort between NASA, the Japan Aerospace Exploration Agency (JAXA) and other international partners. The GPM mission will improve climate, weather and hydrological predictions by providing more accurate precipitation measurements from space.

Ball Aerospace's role in the GPM program included the design, development and fabrication of the GMI. Roughly eight feet tall, the conical-scan microwave instrument is a powerhouse of radiometry. GMI is designed to improve on-orbit calibration and advanced space-borne radiometry by rotating at 32 revolutions per minute, using four very stable calibration points on each revolution to calibrate the data it has scanned. This allows for temporal sampling of rainfall accumulations as well as more frequent and higher quality data collection. GMI's design is based on successful microwave sensors built previously by Ball Aerospace including the Shuttle Radar Topography Mission (SRTM), Spaceborne Imaging Radar-C (SIR-C), GEOSAT Follow-On (GFO) and the Submillimeter Wave Astronomy Satellite (SWAS).

Following launch, Ball Aerospace will provide post-delivery support at NASA's Goddard Space Flight Center (GSFC) and launch site as well as post launch support. Ball Aerospace & Technologies Corp. supports critical missions for national agencies such as the Department of Defense, NASA, NOAA and other U.S. government and commercial entities. The company develops and manufactures spacecraft, advanced instruments and sensors, components, data exploitation systems and RF solutions for strategic, tactical and scientific applications.

MSG-3 satellite ready to continue weather-monitoring service
 
7 March 2012
ЦитироватьInternational partners are looking ahead to the newest member in a series of weather satellites that deliver images to European forecasters: MSG-3 is set for launch this summer.
 
The Meteosat Second Generation (MSG) satellites are designed to improve weather prediction.



The first in the series, MSG-1 – also known as Meteosat-8 – was launched in 2002. MSG-2 followed three years later. Both have been successful in continuing the legacy of the operational meteorological satellites that started with Meteosat-1 in 1977.

The MSGs offer more spectral channels and are sensing Earth at a higher resolution than the previous Meteosat satellites.

The series returns highly detailed imagery of Europe, the North Atlantic and Africa every 15 minutes for use by meteorologists and national weather forecasters.

To guarantee the continuity of service, the third in a planned series of four satellites is on track for launch in June.

Shortly after liftoff from Kourou, French Guiana, it will be injected into geostationary orbit at an altitude of 36 000 km over the equator.

ESA has developed the satellites in close cooperation with Eumetsat – the European Organisation for the Exploitation of Meteorological Satellites – and is responsible for the complex launch and early orbit phase. About ten days after launch, Eumetsat will take over routine operations.

Along with keeping track of cloud development and temperature to improve weather forecasting accuracy, MSG-3 has two secondary missions in the areas of radiation and rescue.

The Global Earth Radiation Budget payload measures energy radiated by Earth. This radiation balance across day and night gives insight into atmosphere circulation and energy distribution.

Meanwhile, the Search and Rescue transponder receives and relays distress signals from beacons within its field of view.

On Wednesday, MSG-3 builder Thales Alenia Space hosted a media event in Cannes, France.

Director of ESA's Earth Observation Programmes, Volker Liebig outlined the innovations that the mission has made in weather monitoring.

"The latest MSG satellite will continue to deliver precise data in a wide range of spectral bands to ensure high accuracy in weather forecasting in the years to come, and keep close track on cloud development," said Prof. Liebig.

The Eumetsat Director-General, Alain Ratier, spoke about the success of the first two MSGs and the importance of continuing Meteosat's vital services, while Eumetsat Meteorological Scientist Philip Watts detailed how MSG-3 observes Earth's atmosphere and surface.

The Director of Optical Observation & Science for Thales Alenia Space, Jean-Jacques Juillet, also presented on how the MSG satellites are built and how extensive tests ensure reliable operations in the years to come.

The presentations were followed by a visit to Thales Alenia Space's cleanroom, where the satellite is currently being held.

Last month, MSG-3 underwent an intensive, two-day test to validate the full set of flight procedures such as receiving commands and delivering data.

During a simulation campaign this month, engineers will train the mission control teams, particularly on how to solve contingency situations if anything goes wrong.

DARPA запускает программу разработки дешёвых военных микроспутников

Цитировать...Которые смогут обеспечивать разведывательными снимками тактические подразделения армии США непосредственно на поле боя. По замыслу Управления перспективных исследований Министерства обороны США (DARPA), любой солдат в любом регионе мира со своего планшета будет получать такую информацию за относительно короткое время.

Сегодня развёрнутые в полевых условиях войска армии США не имеют доступа в реальном времени к данным спутниковой разведки. Точнее, получить спутниковые снимки можно, но не вовремя и нерегулярно. Причин несколько: спутники проходят над одним и тем же регионом по расписанию, а не висят постоянно над районом боевых действий. Да и на тактическом уровне нет средств, позволяющих напрямую получать информацию с орбиты, не говоря уже об ограниченной пропускной способности инфоканалов и требованиях секретности.

«Мы представляем себе созвездие микроспутников (их стоимость при этом составляла бы лишь малую часть от стоимости воздушной разведки), которое позволило бы каждому солдату по нажатию на планшете кнопки «Покажи меня на местности» получать в течение не более 90 минут спутниковую картинку района боя, чтобы основывать на ней текущее планирование», — поясняет Дэйв Барнхарт, возглавляющий SeeMe. Для этого, по его мнению, нужно иметь простые в производстве спутники стоимостью в $500 тыс. за штуку, что потребует использования инновационных нетрадиционных аэрокосмических технологий, позволяющих развёртывание массового производства. В том числе здесь понадобится привлечение сторонних производителей для создания продвинутой элементной базы для спутников, включая новые технологии в области оптики, энергоснабжения спутника, его двигательной системы и средств связи, без чего требуемое снижении массы и габаритов новых орбитальных аппаратов недостижимо.

Объявление конкретных тендеров по новой программе DARPA состоится 27 марта. Однако основные направления уже заявлены. Среди них разработка быстрых в развёртывании, дешёвых технологий производства оборудования для спутников (в этом управление надеется заинтересовать производителей и разработчиков мобильных телефонов). К созданию новых двигательных систем (спутники должны менять траекторию на орбите) планируется привлечь... автопредприятия, обслуживающие гоночную индустрию. В частности, это касается систем на базе оксидов азота под высоким давлением и при низкой температуре. Разработка новых электронных компонентов ляжет на производителей электроники для промышленного оборудования. В области клапанных технологий основным исполнителями, по DARPA, станут производители медицинских пневмоклапанов. «Новая оптика» ляжет на плечи разработчиков нетрадиционных радиопрозрачных мембран и высококачественных линз.

По представлению DARPA, спутниковая группировка SeeMe может состоять из двух дюжин аппаратов, каждый из которых будет находиться на своей предельно низкой орбите (предположительно, около 100 км) не более 60–90 дней, после чего полностью (благодаря малым размерам) сгорать в атмосфере, не оставляя за собой никакого мусора.

Программа будет тесно сотрудничать с другой инициативой управления — ALASA («Воздушная база для космических пусков»), нацеленной на запуск военных КА с борта летательного аппарата, находящегося в атмосфере. При этом известно, что в рамках ALASA стандартный размер запускаемого спутника будет ограничен 45 кг, что, по всей видимости, станет весовым ограничением и для аппаратов программы SeeMe.

Но это данные не визуальной разведки. И вообще они скорее для авиации - где работает ПВО, где радиоизлучающие цели для поражения.
