Astrium... Chilean Air Force Garners New Spatial Capabilities

Astrium’s teams have successfully completed the in-orbit delivery of the...
...SSOT satellite system, which launched from the European spaceport in French Guiana on December 16, 2011. In accepting delivery, the Chilean Air Force (FACh) confirmed that the conditions for the handover of the satellite, FASat Charlie, have been met in full within three months of its launch, thanks to its exceptional performance. The SSOT program comprises a satellite and an operational ground segment based in Santiago, Chile. The satellite has a panchromatic resolution of 1.45m, representing unprecedented performance for a satellite weighing only 117kg. The 20 Chilean engineers operating it were trained at the Astrium site in Toulouse, where the system and satellite were developed and built. SSOT is the latest satellite system to be exported by Astrium. Astrium is playing an active role at FIDAE 2012, which is currently taking place in Santiago, participating in conferences on space that have brought together, under the auspices of the Chilean Air Force, representatives from space agencies across Latin America.

Boeing... Congratulations, Intelsat, You Have A Healthy 27

Boeing [NYSE: BA] has received the first on-orbit signals from Intelsat 22, the first of a series...
...of 702MP (medium power) satellites it is delivering for Intelsat. The signals indicate that Intelsat 22 is healthy and ready to begin orbit raising maneuvers to geostationary orbit followed by operational testing. Intelsat 22 launched on an International Launch Services Proton M / Breeze M vehicle, manufactured by Khrunichev, at 8:10 a.m. Eastern time on March 25th from the Baikonur Cosmodrome in Baikonur, Kazakhstan. Controllers at Boeing's Mission Control Center in El Segundo received initial contact from the spacecraft 15 hours and 40 minutes later and confirmed it is functioning normally.

Intelsat 22 is Boeing's first 702MP spacecraft, which represents the company’s expansion into the medium-sized satellite market. An evolution of Boeing's 702 satellite, the 702MP uses proven technology and a modular design approach to enable faster delivery at a lower cost. Intelsat 22 also carries a government-hosted payload. Following a sequence of orbital maneuvers and on-orbit tests, Intelsat 22 will be placed into geosynchronous Earth orbit, operating in a 72 degrees east orbital slot over the Indian Ocean. Other 702MP satellites currently under construction by Boeing for Intelsat are Intelsat 21, scheduled to launch in the third quarter of this year, and Intelsat 27, scheduled to be completed in 2012 for launch in the first quarter of 2013. Intelsat 27 will carry a UHF hosted payload and offer 20 25-KHz UHF channels capable of serving the U.S. government and other Intelsat clients around the world.

DigitalGlobe... A View To An Impending Conflict... Tongchang, North Korea

DigitalGlobe's online store has just posted a new image of the Tongchang missile base in North Korea.
This is a screen capture of the DigitalGlobe 50cm resolution natural color image of the North Korean launch site at Tonchang-ri. The site is located along the northwestern coast of the country and is reported to be the location of an upcoming rocket launch in April. DigitalGlobe rapidly delivers shareable, high-resolution imagery to provide up to date coverage of events on the ground.

The English http://english.donga.com/ website offers the following information regarding the North Korean site...

North Korea said Friday that its Kwangmyongsong-3 satellite will be launched from the Sohae Satellite Launch Station in Cholsan County, North Pyongan Province, a site that has been known as the Tongchang-ri long-range missile launch center. The Tongchang-ri base was built to replace an aged facility in Musudan-ri, Hwadae County, North Hamgyong Province, on the country`s east coast, but no missile has been launched from the Tongchang-ri base. In June 2009, North Korea moved a Taepodong-2-class long-range missile—believed to be ballistic from a weapon factory near Pyongyang—to the Tongchang-ri base. The projectile was never launched, however.



North Korea's Taipodong-2 missile, capable of packing a nuclear warhead.Observers speculate that the North failed to fix technical glitches on the long-range missile or the Tongchang-ri base`s launch system was imperfect. Pyongyang`s latest announcement pinpointing the base as the launch site indicates the communist country`s confidence that the site has now a perfect launch system.
South Korean military authorities say the Tongchang-ri base, which North Korea began to construct in 2001, has the optimum conditions for launching long-range missiles carrying nuclear warheads. As the site is about 70 kilometers away from the Yongbyon nuclear facility and some 200 kilometers from a missile manufacturing plant near Pyongyang, it takes at most one day to transport and assemble nuclear warheads and long-range missiles. Transporting missiles on a military train from Pyongyang to the older Musudan-ri base took four to five days.

The Tongchang-ri base has a launch pad as high as a 10-story building, an engine combustion test center and a ground control center, and is about three times the size of the Musudan-ri site and far more modernized. In particular, the liquid fuel injection process, a key preparation stage, is conducted automatically in underground facilities, allowing North Korea to avoid U.S. spy satellites` surveillance. Since most of the facilities at the site are automated, multiple missiles can be launched in a short period of time.

"It`s far easier to launch a surprise missile provocation (from the Tongchang-ri base) than from the Musudan-ri base as intended by the North Korean leadership," a senior military official in Seoul said.

Launched at an adjusted angle from the Tongchang-ri base, a missile can fly toward Guam, where U.S. Pacific Command units are deployed, through territorial waters of South Korea and China without going over Japanese territory. The low possibility of the rocket vehicle or its debris falling onto Chinese or Japanese shores makes it easier for the North to make its nuclear gamble without provoking neighboring countries. The Tongchang-ri base is only about 80 kilometers away from the mouth of the Yalu River, which forms part of the North Korean-Sino border. Therefore, South Korea and the U.S. would find it tough to take military action in the event of war because an attempt at a surgical strike or air raid on the base could trigger a Chinese reaction. In addition, missiles launched from the base have a lower risk of being intercepted. Those launched form the Musudan-ri base fly at a low altitude in early stages after launch and have a high risk of being shot down by SM-3 missiles launched from a U.S. or Japanese destroyer in the East Sea. Those launched from the Tongchang-ri base go into high altitude while flying over North Korean territory, lowering the risk of being intercepted.

SRI + University Of Michigan... RAX Wracks Up Auroral Amazements

Researchers from SRI International and the University of Michigan have taken the first-ever measurement of...
...naturally occurring auroral turbulence recorded using a nanosatellite radar receiver. The research was done with support from the National Science Foundation (NSF) and NASA's Educational Launch of Nanosatellites (ELaNa) Initiative. The distinctive radar echoes recorded on March 8th were taken with the Radio Aurora Explorer (RAX) CubeSat. The RAX nanonsatellite measured turbulence over Fairbanks, Alaska, that was a direct result of a geomagnetic storm triggered by the largest solar flare in the past five years. The Earth's high latitude ionosphere, a region of the upper atmosphere associated with solar-driven aurora or "northern lights," becomes highly unstable when large currents flow during geomagnetic storms. RAX was specifically designed by SRI and the University of Michigan to measure this auroral turbulence from an orbital vantage point inaccessible to traditional ground-based radars.

"The RAX radar echo discovery has convincingly proved that miniature satellites, beyond their role as teaching tools, can provide high caliber measurements for fundamental space weather research," said Therese Moretto Jorgensen, Ph.D., Geospace program director in the Division of Atmospheric and Geospace Sciences at the National Science Foundation. The project's mission was to use small satellites called CubeSats to remotely explore formation of charged particle filaments created in response to intense electrical currents in space. These plasma structures, a form of turbulence called field-aligned irregularities (FAIs), can distort communication and navigation signals such as global positioning systems (GPS). During the recent solar flare, RAX measured FAI echoes using the Poker Flat Incoherent Scatter Radar (PFISR), an NSF research radar operated by SRI.

"The recently collected radar echoes allow us to determine the root cause and to possibly predict future disturbances in the auroral ionosphere - disturbances that can severely compromise communication and GPS satellites," said Hasan Bahcivan, Ph.D., a research physicist in SRI's Center for Geospace Studies, and principal investigator of the RAX mission. A team of University of Michigan students under the direction of James Cutler, Ph.D., an assistant professor in the Aerospace Engineering Department, designed, built, and operated the satellite and gathered the radar echo data.

RAX was the first CubeSat to be selected as part of an NSF program to use small satellites for space weather and atmospheric research. The RAX CubeSat is a three liter satellite weighing three kilograms. It was launched by NASA on October 28, 2011, and has since completed 18 experiments.

EUMETSAT... New SAF Project Impetus

The second Continuous Development and Operations Phase (CDOP-2) for EUMETSAT’s Satellite Application Facility (SAF) network...
...which began this month will improve and expand the portfolio of SAF products and services over the next five years. CDOP-2 follows the successful CDOP-1 over the last five years, during which the eight SAFs developed high-quality products and distributed them to users, benefitting EUMETSAT Member and Cooperating States and a worldwide user community.

Among the achievements of the entire SAF network, the following examples can be highlighted: the SAF on Numerical Weather Prediction (NWP SAF) and SAF on Radio-Occultation Meteorology (ROM SAF) have developed software for users and NWP centers, allowing the assimilation of satellite data products to support improvements in forecasts. The SAF on Climate Monitoring (CM SAF), as well as the SAF on Ocean and Sea Ice (OSI SAF) and the SAF on Ozone and Atmospheric Chemistry Monitoring (O3M SAF) have generated long-term homogeneous time series to support the analysis of climate variability over the past decades. The SAF on Support to Nowcasting and Very Short Range Forecasting (NWC SAF) and the SAF on Support to Operational Hydrology and Water Management (H SAF) have developed software packages and data products with high relevance for forecasting weather and its impact on the hydrological system, which are helpful in particular in severe meteorological situations. Finally, the SAF on Land Surface Analysis (LSA SAF) has developed products and services related to vegetation and land surface parameters, not only for users in Europe, but also in Africa and South America.

During CDOP-2, the eight SAFs will continue the operation and data products developed during CDOP-1 and will also conduct the necessary improvements. In addition, new products will respond to the evolving needs of the European Meteorological Services and other users. As the SAFs are an integral component of the overall EUMETSAT application ground segment, during CDOP-2, they will prepare for the exploitation of the potential of the next generation of EUMETSAT satellites, Meteosat Third Generation (MTG) and the EUMETSAT Polar System Second Generation (EPS-SG), taking advantage of enhanced and completely new sensors. They will begin the scientific definition and development of MTG and EPS-SG products, work which will be finalized during CDOP-3 between 2017 and 2022, when these satellites become operational.
CDOP-2 activities and the expansion of product portfolios will contribute to relevant international initiatives. This includes Global Monitoring for Environment and Security (GMES), the Global Framework for Climate Services (GFCS) and the World Meteorological Organization’s Sustained, Coordinated Processing of Environmental Satellite Data for Climate Monitoring (SCOPE-CM) initiative.

Thales Alenia Space... Ministerial Meetings @ Cannes

On Thursday, March 22nd, Thales Alenia Space welcomed to its Cannes plant...
...Laurent Wauquiez, the French Minister for Higher Education and Research. He was accompanied on his visit to the plant by Bernard Brochand, Deputy Mayor of Cannes, Yannick d'Escatha, President of French space agency CNES and Reynald Seznec, President and CEO of Thales Alenia Space. Mr. Wauquiez was visiting the region to present French space strategy. Speaking at Cannes city hall, he emphasized the importance of challenges facing industry in today's economic environment. He first visited Thales Alenia Space's facilities. The company is a world leader in a wide range of space markets, including telecommunications, navigation, meteorology, environmental management, defense, Earth observation and science, and is also the leading private sector employer on the French Riviera.

During their visit, the ministerial delegation could observe first-hand the specific qualities of this high-tech facility, which offers satellite test and integration facilities unrivaled in Europe – more than 13,500 square meters of Class 100,000 clean rooms, including a single space spanning 8,700 square meters for satellite assembly and testing. Cannes also produces the most powerful optical instruments in Europe, namely Pleiades and CSO for very-high resolution Earth observation, as well as the IASA (Infrared Atmospheric Sounding Interferometer), renowned for its accuracy in analyzing the chemical composition of the atmosphere. The instruments are assembled in a 600 square meter clean room which is Class 100—an extreme level of cleanliness comparable to that used by the pharmaceutical industry.
Laurent Wauquiez congratulated Thales Alenia Space for its position as the world leader in satellite constellations, as shown by contracts for O3B, Globalstar and Iridium NEXT. He was also able to visit the integration rooms where the W6A, W3D and Yamal 402 geostationary communications satellites were being integrated. During the visit, Thales Alenia Space was also able to spotlight its lead role on Meteosat. Counting on its 7,200 employees, Thales Alenia Space is the world leader in (geostationary) weather satellites such as Meteosat since 1977. After building the seven first-generation Meteosat satellites as prime contractor, the company was selected in the mid-1990s to deliver four Meteosat Second Generation (MSG) satellites. The third MSG is now slated for a June 19th launch from Kourou, French Guiana. Most recently Thales Alenia Space was also selected to supply the Meteosat Third Generation comprising six satellites: four imaging models and two atmospheric sounders.

USAF's SBIR Satellite Better Than Best Report

The satellite is currently undergoing rigorous certification processes, and is meeting or exceeding performance requirements...

The first Space Based Infrared Systems geosynchronous Earth orbit satellite, currently undergoing a rigorous operational certification process, is meeting or exceeding performance requirements, and on track to be delivered into operations.

Within two months after launch, SBIRS began sharing initial GEO-1 satellite data with technical intelligence mission partners in order to enable early assessments of sensor performance.

On-orbit performance of the first GEO-1 satellite has proven superb.  At the payload level, the GEO sensors are detecting targets 25 percent dimmer than requirements with an intensity measurement that is 60 percent more accurate than specifications.  The payload pointing is nine times more precise than required, which is a key confidence measure for achieving a system level line-of-sight accuracy well within specification.  

The SBIRS GEO-1 satellite includes sophisticated scanning and staring sensors that deliver improved infrared sensitivity and target area scan rates over the current constellation.  The scanning sensor provides wide area surveillance of missile launches and infrared phenomena across the earth, while the staring sensor can be used to observe smaller areas of interest with superior sensitivity and revisit time.  

While the satellite and its respective ground systems continue final system tuning through May of this year, interim mission performance results indicate that the system already demonstrates the ability to meet more than 90 percent of Air Force Space Command's performance requirements for operational use.  The remaining performance refinements are on track to be completed prior to the formal testing campaign slated to begin in June.  

"We've been extremely pleased with the performance of this first-of-its-kind spacecraft," said Col. James Planeaux, director of the Infrared Space Systems Directorate.  "We fully expect GEO-1 to enter services as an invaluable military asset that will help protect our nation and its allies for many years to come."

Live GEO-1 data will be included in the nation's missile warning and theater event networks during a trial period and operation utility evaluation this fall.  This first GEO satellite is expected to be certified for operations by U.S. Strategic Command by the end of 2012.

As one of the nation's highest priority space programs, SBIRS delivers global, persistent, taskable infrared surveillance capabilities to meet 21st-century demands for early warning of missile launches and simultaneous support to other critical missions including missile defense, technical intelligence, and battlespace awareness.  

The SBIRS architecture features a mix of GEO satellites, payloads in highly elliptical Earth orbit, and associated ground hardware and software that provides a timely, accurate and clear infrared view of any region of interest around the globe during peacetime and all levels of conflict.  The GEO satellites replace and improve upon the legacy Defense Support Program satellites, offering enhanced sensor flexibility and sensitivity to provide global, taskable, 24/7 infrared surveillance capabilities to support the warfighter.

The SBIRS development team is led by the Infrared Space Systems Directorate at the U.S. Air Force Space and Missile Systems Center, Los Angeles Air Force Base, California.  Lockheed Martin Space Systems Company, Sunnyvale, California, is the SBIRS prime contractor, with Northrop Grumman Electronic Systems, Azusa, California, as the payload integrator.  The 14th Air Force operates the SBIRS system.

U.S.A.F.'s 4th Space Operations Squadron... Huge Step Forward — Safe + Secure

Recently, the men and women of the 4th Space Operations Squadron, in partnership with the Space and Missile Systems Center's Protected SATCOM Division, have...
...taken huge steps to ensure protected, survivable satellite communication for years to come. Initial payload contact was made October 29th, marking the start of on-orbit testing of the first Advanced Extremely High Frequency (AEHF) satellite, the newest addition to the Milstar/protected communication satellite family. This initial contact with AEHF was important because, for the first time, it involved 4 SOPS operators and the primary ground system 4 SOPS will use to command and control, the AEHF Satellite Mission Control Subsystem.

The new capabilities of this satellite enhance secure communications both here at home and down range. This new technology, orbiting more than 22,000 miles above the earth, will boost secure global communications bandwidth by a factor of 10. A comparison would be updating from a dial-up internet connection to a broadband line. Instead of just basic data and voice, AEHF has the ability to stream large bandwidth information with the same security provided by the current Milstar constellation. To perform this feat, AEHF will introduce a new Extended Data Rate bandwidth capability, which encompasses both the current Low Data Rate and Medium Data Rate bandwidths along with the higher bandwidths beyond the capability of the current Milstar constellation.
Along with this addition to the Milstar constellation comes new capabilities here. Currently there are three new Advanced Ground Mobile (AGM) command and control centers at various locations. These mobile facilities can command and control the entire constellation as a standalone operations floor if needed during a wartime environment. To ensure the survivability of these platforms, they are housed inside trailers that can be driven or flown to any location on Earth at a moment's notice to ensure continued control of the constellation.

Since October, 4 SOPS and SMC/MCA personnel, along with their contractor partners Lockheed Martin and Northrup Grumman, have been working around the clock to ensure AEHF will seamlessly fit into the Milstar constellation and provide warfighters with unprecedented secure communication capabilities. These tests are proving AEHF is a perfect fit and valuable addition to the current constellation. One significant test validated AEHF's ability to integrate into the Milstar constellation's complex cross-link network. This network allows data to pass from satellite to satellite without the need for ground stations to relay the data. Another successful test AEHF completed proved its ability to perform over-the-air rekey. This critical capability ensures that communications passed between our warfighters remains protected from the enemy.

First contact and the numerous tests successfully completed since that important day are significant milestones representing the culmination of years of planning and development. These milestones are especially important, considering the satellite travelled more than 14 months to reach its final orbit location following a thruster anomaly after its August 2010 launch. The entire team to include, 4 SOPS, SMC/MCA and their industry partners continue to work tirelessly to bring AEHF online for the warfighter and we are excited about the capabilities this new satellite will bring to the fight.

U.S.A.F... Clogged AEHF-1 Rescued

Merryl Azriel of http://www.spacesafetymagazine.com/ reports that 14 months after human error stranded...
...U.S. military Advanced Extremely High Frequency communications satellite (AEHF-1) in the wrong orbit and at risk of exploding, the satellite was finally placed in its correct orbit in October of 2011. A successful test completed on February 29th prepared the AEHF-1 for operations, just two months before the second AEHF satellite is scheduled to launch. “This rescue effort was definitely a very sophisticated and highly technical masterpiece,” said Col. Michael Lakos, chief of the Military Satellite Communications Division at Peterson Air Force Base, Colorado.

It all started a couple days after AEHF-12s August 2010 launch aboard an Atlas V rocket. The satellite successfully reached it’s parking orbit. But the main engines that are needed to circularize the satellite’s orbit refused to work—they kept shutting off. The shut off is a safety feature instituted when a satellite detects a fault in the engines. The question was: what fault?

Experts determined that the fuel line must be blocked. But the attempts to engage the engines had resulted in filling the lines with fuel, thereby putting the satellite at risk of explosion and making it hazardous to attempt another engine fire. Luckily, AEHF-1 has two additional propulsion systems, albeit much less powerful, designed for use in stationkeeping adjustments, not major changes in trajectory. However, by applying small propulsive adjustments hundreds of times over 14 months, ground crews were able to slowly coax the satellite into its proper orbit. The major challenge was keeping it intact in the interim. The satellite had to dodge space debris three or four times and deploy its solar shields much earlier than intended—putting them at risk of degradation from radiation exposure in the van Allen belts.

[color=yellow]The fault for the blocked fuel line was eventually attributed to a piece of cloth that had been placed over the line during manufacturing to protect it from contamination, but was never removed.[/color] “If I had to find the top 10 strange ones, that one would make my list,” said defense analyst Marco Caceres, who tracks rocket and satellite failures as part of his work for the Teal group, an aerospace and defense analysis firm. The Air Force has implemented additional checks for the remaining 5 satellites to be launched as part of the AEHF constellation and docked manufacturer Lockheed Martin $15 million for the mistake.

[quote:acd65fc46c]На систему предупреждения о «космическом мусоре» потратят 65 млн рублей
14 марта 2012

В Роскосмосе собираются потратить 65 млн рублей на создание автоматизированной системы предупреждения об угрозах столкновения «космического мусора» со спутниками и пилотируемыми космическими кораблями, говорится в конкурсной заявке ведомства, размещенной на сайте госзакупок.

Согласно конкурсной документации, система будет направлена на «выявление, прогнозирование, анализ, баллистическое сопровождение опасных ситуаций в околоземном космическом пространстве, включая опасные сближения «защищаемых» космических аппаратов с космическими объектами «риска», сходы с орбит и падение космических объектов «риска», установление фактов разрушения космических объектов», передает «Интерфакс».

На первом этапе система должна будет обеспечить сопровождение 30 «защищаемых» космических аппаратов и выдавать предупреждение об угрозе за 30 часов, давая оценку вероятности столкновения. Кроме того, система должна прогнозировать время схода космических объектов с орбиты и район их падения за месяц до события.
Согласно конкурсной документации, система будет отслеживать ситуацию на геостационарных, высокоэллиптических и средневысоких орбитах, в низкоорбитальной области околоземного пространства, проводить расчет параметров солнечной и геомагнитной активности. Последние два параметра необходимы для баллистических расчетов орбит космических объектов, уточняется в документации.

В требованиях Роскосмоса указано, что работы по контракту должны быть завершены 25 ноября 2012 года.

Главный информационно-аналитический центр, выступающий в документации под названием «Центральное ядро» планируется создать на базе Центра управления полетами (ЦУП, Королев, Московская область).

В интересах системы также планируется задействовать первый отечественный сверхширокоугольный телескоп АЗТ-33ВМ с главным зеркалом диаметром 1,5 м.

Как сообщалось, Роскосмос создает на базе ЦУПа орган по контролю за космическим мусором и обеспечением безопасности космических кораблей и аппаратов.

«По решению руководства Роскосмоса для контроля за развивающейся ситуацией на основе аппаратно-программных и связных средств Центра управления полетами создается автоматизированная система предупреждения об опасных ситуациях в околоземном космическом пространстве», - сообщили в ЦУПе в январе 2011 года.

По словам представителя ЦУПа, такое решение принято в связи с драматическим завершением полета межпланетной станции «Фобос-Грунт», а также серьезным засорением космического пространства «космическим мусором» и созданной им угрозой для космической техники на орбите.

«События последних месяцев подтвердили насущную потребность для современной космонавтики в развитии нового, но все более актуального направления: определения средств и возможностей борьбы с засорением околоземного космического пространства объектами искусственного происхождения», - сказал собеседник агентства.[/quote:acd65fc46c]

SPACEBEL + VAST... PRIME Pride

SPACEBEL will sign all of the necessary contract pre-agreements with the...
...Vietnam Academy of Science and Technology (VAST) for the production of an Earth observation mini-satellite to be launched in 2017. After several years of negotiations, the SPACEBEL consortium was selected in July of 2011 on the basis of their technical proposal and also due to the continuous support of the Belgian Government, both at the Federal and regional levels. With this 100 percent Belgian satellite named VNREDSat-1b (Vietnam Natural Resources, Environment & Disaster Monitoring satellite), Vietnam will be able to independently monitor its territory and environment. Weighing 130kg, the small spacecraft will play an important role in the field of natural resources management (agriculture, forests), will ensure a better follow-up and prediction of climate changes, pollution detection in the seas, as well as help to minimize the impact of natural disasters, and so on.

This project representa a total value of more than 60 million euros. SPACEBEL will rely upon the expertise of various Belgian partners: QinetiQ Space, AMOS, Deltatec, the Space Centre of Li

Astrium... Upcoming Heavyweight Flight

Astrium is completing the mission preparation for the Automated Transfer Vehicle ATV-3.
On March 23, 2012, the unmanned cargo resupply spacecraft named after the Italian physicist Edoardo Amaldi will be launched on its five-month mission to the International Space Station (ISS) from the Europe’s spaceport in Kourou, French Guiana, on board the European Ariane 5  ES launcher. Astrium is the industrial prime contractor for both the Automated Transfer Vehicle (ATV) and the Ariane 5 European launcher. This will be the third ATV mission to ferry supplies to the International Space Station. ATV could be currently considered as the ‘best spaceflight robot’ due to its innovative technologies which enable it to dock automatically with the ISS at about 28,000 km/h.

The Edoardo Amaldi ATV is currently awaiting transfer to the launch pad, having completed an extensive series of tests over the last few weeks. These included combined tests to check the interface between the launcher and ATV, verification of the air cleanliness in the cargo module, and pressure and leak tests. The Integrated Cargo Carrier (ICC) of the Edoardo Amaldi has been loaded to capacity with supplies for day-to-day use including food, clothing, toiletries, consumables, tools, medical supply packages, replacement parts and new experiments. Known as ‘dry cargo’, this constitutes a total weight of 2.2 tons. Around 1.6 tonnes of this dry cargo is the ‘nominal load cargo’, which is loaded onto the vehicle a few months before the launch, while the remaining 600kg—known as ‘late load cargo’—are added to the ATV just three weeks prior to launch. Late load cargo includes perishable items and experiments that can only be kept in storage for a limited time.

The ATV’s various tanks will carry more than four tons of propellants and gases to the International Space Station (the ATV total is more than six tons including propellant needed for its own journey). The propellants will be used for multiple purposes, including attitude control, maneuvering, and refuelling the ISS. The Edoardo Amaldi ATV will also transport 285kg of water and 100kg of oxygen to the ISS. With a take-off weight approaching 20 tons, the ATV-3 is one of the heaviest payloads ever carried into orbit by an Ariane launcher.

The 2.2 tons of cargo and 1,062 individual items are divided up into a total of 153 bags to enable the astronauts to unload the Edoardo Amaldi on a gradual basis, according to their requirements. One of the items the ATV-3 will be carrying is a new ventilator for the European Columbus laboratory. Regular replacement of this lab component is just one of the tasks undertaken by Astrium as part of the Exploitation Contract which was signed with ESA for the European components of the ISS. The Edoardo Amaldi ATV will also be carrying a whole series of new experiments to the ISS. For instance, the cargo includes a human biology experimental device which will investigate the body’s energy management processes under weightless conditions. This experiment will provide important insights which can be applied to future long-term missions in weightless conditions. In addition, the BIOLAB facility in the Columbus research laboratory will be equipped with a module which will make it possible to deliver precisely defined supplies of clean air to the experiments performed in the laboratory.

The ATV-3 payload will also include toothbrushes of different bristle hardness and toothpaste of various flavors as part of efforts to make the astronauts feel more at home on the ISS. One of the cargo bags will even contain LEGO® Technic sets, part of a range of experiments that NASA is conducting for a special series of lessons for school pupils back on Earth.

Naval Research Laboratory + USCG... Taking The Time To Test TacSat-4

The U.S. Coast Guard Cutter HEALY (WAGB 20) successfully experimented...
...with the NRL’s TacSat-4 communications satellite, January 24th, by communicating from the Bering Sea off the western coast of Alaska to Coast Guard Island, Alameda, California. Returning from an escort and icebreaking mission to Nome, Alaska, assisting the Russian tanker Renda delivery of emergency fuel to the town, USCGC HEALY—the Coast Guard’s only polar icebreaker—was approximately 260 nautical miles south of the Arctic Circle at the time of the test. Deployed into a unique, highly elliptical orbit, with an apogee of 12,050 kilometers, TacSat-4 helps augment current geosynchronous satellite communication by including the high latitudes. The experiment was the first in a series of planned steps that aim to demonstrate TacSat-4's utility in the polar and arctic regions.

Also participating in communications with HEALY was the U.S. Army Space and Missile Defense Battle Lab (SMDBL) located in Colorado Springs, Colorado. The SMDBL team was conducting portions of the ongoing TacSat-4 Joint Military Utility Assessment (JMUA). Managed by the U.S. Naval Research Laboratory, Naval Center for Space Technology, TacSat-4 is an experimental spacecraft that will test advances in several technologies and SATCOM techniques. It will augment the existing fleet with an additional space asset to provide communications to otherwise underserved users and areas that either do not have high enough priority or do not have satellite visibility. The Office of Naval Research (ONR) is funding the first year of TacSat-4 operations. The Operationally Responsive Space (ORS) Office is leading and funding the JMUA of TacSat-4.
