Orbital Sciences... Blow 'Em Up Real Good (Missile)

[SatNews] Nothing truly enjoys being the target of an explosive device — save for those vehicles specifically designed to test the accuracy of missiles. Based on the Pegasus space launch vehicle, Orbital Sciences Corporation (NYSE: ORB) major new contract by the U.S. Missile Defense Agency (MDA) to supply this craft as Intermediate-Range Ballistic Missile (IRBM) target vehicles for use in future tests of missile defense systems. The seven-year contract, which covers development and production of as many as 22 target rockets and related systems over the 2011-2018 period, has a firm value of approximately $230 million for the first eight vehicles to be delivered by 2015, with up to $870 million in contract options for 14 additional vehicles, countermeasures equipment, modeling and simulation support, logistics activities and launch services to be provided from 2012 to 2018. The company's IRBM target is a multi-stage vehicle that will be air-launched from a standard C-17 cargo aircraft via a parachute extraction system, providing MDA with increased flexibility in testing its Ballistic Missile Defense System (BMDS).
The original Pegasus technology has spawned numerous derivative launch vehicles that have supported U.S. Government and commercial satellite customers for over two decades. It was adapted to create the Taurus and Minotaur space launch vehicle programs, as well as the launch platform for NASA's Hyper-X hypersonic research missions. In addition, significant flight-proven elements of Pegasus were incorporated into the company's Orbital Boost Vehicle missile defense interceptor to reduce development timelines and assure high levels of reliability, the same attributes that will now be applied to the IRBM targets program. More than 150 Pegasus-derived space and suborbital launchers are expected to be produced over a 30-year period from 1988 to 2017.

Boeing ...A-O-Ka- x 3 Pass Preliminary Design Review

[SatNews] It's always good news when projects are successfully nearing completion.

Today Boeing [NYSE: BA] announced that it has completed the Preliminary Design Review (PDR) for the Inmarsat-5 spacecraft and hosted payloads. Boeing is building three Ka-band satellites to add to Inmarsat's current mobile satellite services fleet.

The PDR was a comprehensive review that validated Boeing’s design approach to the physical and functional requirements of the spacecraft. The review is the first step toward confirming that the satellites will operate effectively on orbit. The first spacecraft is expected to launch in 2013.

“Boeing’s unmatched commercial satellite heritage and Ka-band satellite communications experience allowed us to rapidly conduct a successful PDR that met Inmarsat’s requirements,” said Craig Cooning, vice president and general manager of Boeing Space & Intelligence Systems. “The satellite design is sound, and the PDR demonstrates progress toward developing these high-power Ka-band satellites to deliver streaming data and communications wherever and whenever needed.”

Successful completion of the PDR allows Boeing to proceed to the Critical Design Review (CDR), the final step before the company begins to assemble the satellite. The CDR is expected to be completed this fall.

Inmarsat, the leading provider of global mobile satellite communications services, signed a contract with Boeing in August 2010 for three 702HP spacecraft to provide its new Ka-band global and high-capacity satellite services. The new satellites will join Inmarsat’s fleet of 11 geostationary satellites that provide a wide range of voice and data services through an established global network of distributors and service providers.

Turkey + Mitsubishi Electric... Communicating Well (Satellites)

[SatNews] Two more satellites are planned to join the two already aloft.

Turkey plans to launch two more communication satellites by 2014, Turkey’s transportation minister said on Monday. The county signed a $571 million deal with Japanese technology firm Mitsubishi Electric MELCO to procure and launch Turksat 4A and Turksat 4B. Speaking at the signing ceremony, Transportation Minister Binali Yildirim said that Turkey also started efforts for production of another satellite, Turksat 5A, by Turkish engineers in a strategic cooperation with the Japanese firm. Currently, Turkey operates two communication satellites, Turksat 2A and Turksat 3A. Last year, another Turkish satellite — Turksat 1C — had "retired" 14 years after it was launched into space.

Yildirim said Turkey decided to launch new satellites due to rising demand and capacity in Turksat, Turkey’s satellite operator. Yildirim said new satellites would help increase Turkey’s satellite capacity by three fold. He added that the deal would also set the ground for a cooperation between Japan Aerospace Exploration Agency (JAXA) and Turkish Space Agency, which is expected to be established next year. Turksat 4A and Turksat 4B will have a lifespan of 30 years. Turkey plans to place Turksat 4A into orbit by the last quarter of 2013. Turksat 4B will be launched in 2014. Turkey also has plans to launch its first intelligence satellite next year. The spy satellite was named "Gokturk" and it is now under construction by Turkish engineers. (Source: TurkishPress.com)

EUMETSAT... 3G Approved (Satellites)

Meteosat 3G satellite, artistic rendition[SatNews] A commitment has been made by the entire 26 EUMETSAT Member States.

Following the approval of Belgium, all of the Member States have now firmly committed to the Meteosat Third Generation (MTG) program. The EUMETSAT Director-General, Dr. Lars Prahm, welcomed the good news and said, “It was not an easy process and the overall financial situation in Europe certainly did not help but I am very pleased to see that all Member States have now approved a vital programme which will assure the future of EUMETSAT’s geostationary observations over Europe, Africa and the Atlantic Ocean over the next few decades.”

Consisting of six satellites, MTG will secure Meteosat weather and climate data for Europe for the next 30 years. Operating from geostationary orbit 36,000 kilometres above the Earth’s surface, MTG will continue the uninterrupted collection of data by Meteosat satellites that began in 1977. Due to advances in technology, MTG will also provide an enhanced service compared to the current Meteosat Second Generation (MSG), bringing significant improvements to the service already provided with an improved imagery mission and introducing the new sounding and lightning missions from geostationary orbit. MTG will operate over a longer period of time and at a slightly lower cost per year of in-orbit lifetime than Meteosat Second Generation (MSG), which it will start replacing in 2018. Through its mission, MTG will introduce major improvements in Numerical Weather Prediction and Nowcasting of severe weather situations. Key applications will include more timely forecasting of severe thunderstorms which cause heavy precipitation and flooding, improved monitoring of aerosols and volcanic dust clouds, as well as air quality monitoring. MTG quick facts...

•Four MTG-I imaging satellites, with the first launched in the 2018 timeframe
•Two MTG-S sounding satellites, with the first launched around 18 months after MTG-I
•Common three-axis stabilized platforms for both MTG-I and MTG-S

Space Florida + Bigelow Aerospace... Sundancing Into Orbital Space (Spacecraft)

Space Florida homepage[SatNews] Space Florida President Frank DiBello and Robert Bigelow, president of Bigelow Aerospace, have signed a Memorandum of Understanding, agreeing to work together to pursue and identify foreign and domestic companies that could benefit from the use of Bigelow’s expandable, orbital space complexes.

Bigelow homepageBigelow currently has two pathfinder expandable systems successfully orbiting the Earth, and plans to build the first of multiple fully-functioning stations by 2015. The initial “Alpha” complex will be comprised of Bigelow’s patented “Sundancer” and “BA 330” modules, which are significantly larger than current modules aboard the International Space Station. Additionally, customer launch and lease rates for the facilities are expected to be extremely cost-efficient for domestic and international customers. Bigelow is marketing eighteen (18) separate human space flight programs with a variety of duration and pricing options, including an option of $28,750,000 for a 30-day astronaut visit. According to Bigelow, if the company attracts enough customers to lease all of the orbiting, inflatable modules on Complex Alpha, it could mean up to 25 launches a year – possibly from Cape Canaveral – to ferry cargo and crew. Module launches could be accommodated by current United Launch Alliance Atlas V rockets or other vendors.

It is intended that this innovative partnership will help build a dynamic future for on-orbit commercial space operations, enhancing overall launch activity, employment, and growth of the aerospace field in Florida. This collaborative business development partnership will also explore approaches to supporting 1/3 scale models of the orbiting outposts in Florida. These models would assist in marketing to new customers as well as simulation of customer requirements and concepts of operations for payloads, prior to flight.

Thales Alenia Space + Globalstar... Perfect Positioning (Satellites)

Thales Alenia Space company info[SatNews] The first four Globalstar Second Generation satellites have been successfully positioned in their operational orbit, marking the start of service for this new constellation.

Artistic rendition of Globalstar's 2G satelliteAfter the launch by Arianespace and Starsem using a Soyuz rocket from Baikonur on October 19, 2010, Thales Alenia Space teams took charge of orbital positioning operations, at the Globalstar control center in Milpitas, California. The Globalstar-2 constellation is comprised of 2G low Earth orbit (LEO) satellites that will provide mobile phone and data services. To ensure global coverage, the satellites will be equally distributed in eight orbital planes, inclined 52 degrees and separated by 45 degrees. For this type of orbital arrangement, optimized orbital positioning maneuvers are used in conjunction with the natural drift from the injection plane to the operational orbital positions, to use as little of the satellites’ own fuel as possible. These maneuvers are in fact long and complex because the new satellites have to be moved to the different orbital planes making up the constellation.

The launcher initially injects the satellites into orbit at an altitude of 920 km. The first satellite reached its operational position in mid-November in plane C at an altitude of 1,414 km, while the three following satellites recently reached their positions in plane B. All four of these satellites have now passed acceptance tests, with both payload and platform showing very satisfactory performance. Furthermore, the quality of the initial calls transmitted by these satellites is excellent. The last two satellites in the first cluster of six to be launched are still in transition orbit at 1,000 km, with an initial orbit-raising maneuver being carried out in December. The new constellation will help ensure service continuity for Globalstar until 2025, as well as providing a platform for an expanded service offering, based on innovative solutions. Each 2G Globalstar satellite weighs about 650 kg at launch, and offers end-of-life power of 1.6 kW and a design life of 15 years. Each satellite has 16 uplink channels (L- and C-band) and 16 downlink channels (C- and S-band).

WISE Wonderments... Stellar Explosions (Imagery—NASA)

[SatNews] This oddly colorful nebula is the supernova remnant IC 443 as seen by NASA's Wide-field Infrared Survey Explorer, or WISE.

Also known as the Jellyfish nebula, IC 443 is particularly interesting because it provides a look into how stellar explosions interact with their environment. IC 443 can be found near the star Eta Geminorum, which lies near Castor, one of the twins in the constellation Gemini. Just like human beings, stars have a life cycle — they are born, mature, and eventually die. The manner in which stars die depends on their mass. Stars with mass similar to the sun typically become planetary nebulae at the end of their lives, whereas stars with many times the sun's mass explode as supernovae. IC 443 is the remains of a star that went supernova somewhere between 5,000 and 10,000 years ago. The blast from the supernova sent out shock waves that traveled through space, sweeping up and heating the surrounding gas and dust in the interstellar medium, and creating the supernova remnant seen in this image.
The supernova remnant IC 443 as seen by WISE. Image credit: NASA/JPL-Caltech/UCLA

What is unusual about the IC 443 is that its shell-like form has two halves that have different radii, structures and emissions. The larger northeastern shell, seen here as the violet-colored semi-circle on the top left of the supernova remnant, is composed of sheet-like filaments that are emitting light from iron, neon, silicon and oxygen gas atoms, in addition to dust particles, all heated by the blast from the supernova. The smaller southern shell, seen here in a bright cyan color on the bottom half of the image, is constructed of denser clumps and knots primarily emitting light from hydrogen gas and heated dust. These clumps are part of a molecular cloud, which can be seen in this image as the greenish cloud cutting across IC 443 from the northwest to southeast. The color differences seen in this image represent different wavelengths of infrared emission.

The differences in color are also the result of differences in the energies of the shock waves hitting the interstellar medium. The northeastern shell was probably created by a fast shock wave (100 kilometers per second or 223,700 miles per hour), whereas the southern shell was probably created by a slow shock wave (30 kilometers per second or 67,100 miles per hour). All WISE featured images use color to represent specific infrared wavelengths. Blue represents 3.4-micron light, cyan represents 4.6-micron light, green represents 12-micron light and red represents 22-micron light. In this image, we see a mixing of blue and cyan in the southern ridge that is not often seen in other WISE images. The northeastern shell appears violet, indicating a mixture of longer infrared wavelengths from cooler dust (red) and shorter infrared wavelengths from luminescent gas (blue).

Northrop Grumman... Webb Work (Satellite)

[SatNews] The first completely finished primary mirror segment for NASA's James Webb Space Telescope has passed its final cryotest in the X-ray & Cryogenic Facility at NASA's Marshall Space Flight Center in Huntsville, Alabama.

This last successful cryotest demonstrates that the mirror segment, an engineering development unit and flight spare, has fully demonstrated its ability to meet the needs of the Webb Telescope program. Northrop Grumman Corporation (NYSE:NOC) is leading the Webb Telescope design and development effort for the space agency's Goddard Space Flight Center. Ball Aerospace, Boulder, Colorado, is the principal optical subcontractor for the Webb Telescope program, responsible for developing the telescope optics.

The mirror segment was recently coated to maximize its reflectivity in the infrared part of the spectrum. During the final cryotest, the mirror segment is chilled to -415 degrees F and telescope engineers take extremely detailed measurements of how the mirror's shape changes as it cools. Cryotesting verifies that the mirror will change shape into the exact optical prescription needed to accurately image distant stars and galaxies. The primary mirror engineering development unit will be closely followed by 18 primary mirror flight segments. The segments will be coated before the final cryotest at Marshall, the world's largest X-ray telescope test facility, which is also a unique site for cryogenic, clean-room optical testing. The James Webb Space Telescope is the world's next-generation space observatory and successor to the Hubble Space Telescope. The most powerful space telescope ever built, the Webb telescope will observe the most distant objects in the universe, provide images of the very first galaxies ever formed and see unexplored planets around distant stars. The Webb telescope is a joint project of NASA, the European Space Agency and the Canadian Space Agency.

Iran... Speaking Of Spaceports (Launch)

[SatNews] Iran plans to construct its second spaceport, Communications and Information Technology Minister Reza Taqipour said on Sunday.

Taqipour told the Mehr News Agency, "At present, there is only one space launch base in the country... but there are some geographical limitations (in regard to launching satellites and missiles)." Iran then completed a feasibility study on the construction of a second spaceport in order to overcome limitations, he added. The current launch site is located in Semnan Province, and in recent years, two spacecraft have been launched from the center. Taqipour also said there are two telemetry tracking and control centers in the country that can track and control satellites launched from Iran, but they belong to other countries. Iran successfully launched their Kavoshgar 3 (Explorer 3) manufactured satellite that carried a rat, turtles, and worms in February of 2010. Iran also plans to send actual people into space within 10 years.

SpaceX Dragon Launches... Mystery Payload (Cheese In Space!)

[SatNews] While SpaceX was planning the first civilian launch from the Cape yesterday, rumors were flying about the 'secret' payload on board the Dragon.
Twenty-four hours later, the launch was successful — the Dragon cycled twice at speeds of up to 17,000 miles per hour all the while carrying a large round mystery payload that turned out to be — cheese — in a tribute to Monty Python!

Payload revealed. Photo Credit: Chris Thompson, SpaceXUpon landing successfully in the Pacific Ocean the Dragon was recovered and... the cheese wheel was found to be in fine condition. Imagine the cheers that went up as the seal was broken and the payload inspected.

Guess that's why when they were smiling for the press they said, "Cheese!" No one said space stuff had to be boring...perhaps some crackers to go with the cheese?

Army's first satellite in 50 years rides into orbit aboard SpaceX vehicle

HUNTSVILLE, AL -- The Army's first satellite in more than 50 years piggybacked into low earth orbit Wednesday as part of SpaceX's launch of its two-stage Falcon 9 booster rocket and prototype reusable space capsule, Dragon.
About 45 minutes after the 8:43 a.m. CST liftoff, the Army SMDC-ONE (Space and Missile Defense Command - Operational Nanosatellite Effect) nanosatellite deployed from the second stage of the rocket, which also carried other payloads.

Ground stations at the Space and Missile Defense Command/Army Forces Strategic Command headquarters on Redstone Arsenal and at Colorado Springs, Colo., quickly began receiving data from the satellite about the health of its systems.

"The launch and deployment of the first SMDC-ONE nanosatellites is intended to demonstrate the concept of sending and receiving data from unattended ground sensors using small, low-cost, low earth orbit satellites," said Lt. Gen. Kevin T. Campbell, commanding general, Army Space and Missile Defense Command.

The nanosatellites would be constantly overhead, collecting data from ground sensors and relaying it over the horizon to commanders, according to John London, program manager in the SMDC Technical Center. The nanosatellites can also be used for communications and, if the concept proves feasible, could quickly be configured for other specific missions.

The ultimate goal is to have satellites that cost around $300,000 each and are either secondary payloads aboard other rockets - as in Wednesday's SpaceX launch - or that could be put in orbit virtually on demand by a new class of smaller boosters, the [color=yellow]Multipurpose NanoMissile System[/color].

Dynetics in Huntsville is already working on MNMS, which has a goal of putting a nanosat in orbit for about $1 million. The team hopes to have a sub-orbital flight test, complete with satellite, in 2011, and an orbital test in 2012.

The satellite launched Wednesday will test the SMDC-ONE data and communications relays with ground stations and is expected to be in orbit about 30 days. Then, it will drop back toward Earth and, because of its small size and weight, is expected to be destroyed on re-entry into the atmosphere.

This is the Army's first satellite development program since the 1960 Courier 1B communications satellite. The SMDC-ONE satellites each weigh less than 10 pounds and are about 14 inches long.

In April 2009, SMDC took delivery of eight of the four-kilogram satellites at the end of a one-year contract effort led by Miltec of Huntsville, Pericle Communications Company, of Colorado Springs, Colo., and Clyde Space Limited of Glasgow, Scotland.

Two more of the SMDC-ONE satellites are scheduled for a launch in late 2011.

This Ariane 5 ES version of Arianespace's workhorse heavy-lift launcher is being assembled in the Spaceport's Launcher Integration Building, where activity began mid-week with the core cryogenic stage's positioning over the mobile launch table. It was followed by rollout of Ariane 5's two large solid rocket boosters for mating with the core stage. Ariane 5 is the latest version of Europe's Ariane launcher family, which began operations in 1979 and has orbited a full range of payloads that include telecommunications satellites, Earth observation and meteorology platforms, space exploration probes, along with defense and security spacecraft.

Arianespace operates two standardized versions of Ariane 5: the ES version for flights to low- and medium-Earth orbits; and the Ariane 5 ECA for GTO (geostationary transfer orbit) missions. The ATV for next February's flight is named after German astronomer/mathematician Johannes Kepler, and will be the second such unmanned logistics spacecraft launched by Ariane 5. These ATVs are part of Europe's contribution to the International Space Station's operation and maintenance

December 08, 2010Thales Alenia Space to Build W3D Satellite for Eutelsat Communications

Eutelsat Communications, a satellite operator, has contracted Thales (News - Alert) Alenia Space to build it a W3D satellite that will replace the W3B spacecraft lost after its launch on Oct. 28.

W3D will be co-positioned with Eutelsat's (News - Alert) W3A satellite at 7 degrees East to expand operational capacity at this longstanding location to 70 transponders from 44. It is built on Thales’ Spacebus 4000 platform. Eutelsat customers with the new satellite will be receiving additional capabilities to expand their business, and the company will be able to increase in-orbit security and inject new capacity to 7degrees East to capture business opportunities in Europe, the Middle East, Africa and Central Asia.

According to the company, the W3D satellite features 56 Ku and Ka-band transponders and is supposed to deliver three key coverage zones: high-power Ku-band coverage of Europe with a beam centered over Central Europe and Turkey, particularly optimized for direct-to-home (DTH) reception. The satellite can offer extensive coverage across Europe, North Africa and the Middle East as far as Central Asia, via a Ku-band beam for professional video links and data networks and Ku-band coverage of Sub-Saharan Africa and Indian Ocean islands for regional telecommunications and Internet services. Ka-band frequencies in Europe and Ku-band frequencies in Africa will be blended to interconnect the African coverage with Europe.

Officials with Eutelsat explained that working in close collaboration with the industry, they are now pushing ahead with timely delivery of W3C (News - Alert) to 16degrees East in mid-2011 and has started the clock on the W3D program, which will be completed in 24 months. The company’s clear objective is to apply to both programs all appropriate recommendations of the Inquiry Board currently investigating the loss of W3B. Even as the Inquiry Board continues its work, Eutelsat is already implementing measures to tighten control of the industry's manufacturing processes.

Arianespace To Launch Sicral 2 Satellite in 2013

PARIS — The French-Italian Sicral 2 military telecommunications satellite will be placed into geostationary orbit as a co-passenger on Europe’s heavy-lift Ariane 5 ECA rocket in late 2013 under a contract the Arianespace commercial launch consortium announced Dec. 6.

Sicral 2, expected to weigh about 4,400 kilograms at launch, will carry separate French and Italian SHF and UHF communications payloads to be used independently by French and Italian forces. It will operate at 37 degrees east.

Sicral 2 will also back up existing satellite bandwidth provided by France and Italy to the 28-nation NATO alliance under a long-term contract shared with Paradigm Secure Communications of Britain.

Telespazio of Rome will be Arianespace’s customer for the Sicral 2 launch. Under a May contract with the French and Italian defense ministries, Telespazio was given responsibility for securing the launch, as well as overseeing early-orbit maneuvers and the Sicral 2 ground |segment.

The Sicral 2 contract is valued at 295 million euros ($398 million). Of that amount, 193 million euros is for construction of the satellite and design of the ground communications network by Thales Alenia Space, with the remaining 102 million euros going to Telespazio.

For Evry, France-based Arianespace, winning the contract was especially important because Italian officials had gone outside of Europe, to the U.S.-based Sea Launch Co. commercial launch company, for the launch of Italy’s Sicral 1B satellite in 2009.
