Thanks to Atlantis\u2019 STS-135 mission, the ISS is in no risk from a logistics standpoint, but the future of the Station\u2019s full utilization role \u2013 not least in the year 2013 \u2013 requires the support of both SpaceX\u2019s Dragon and Orbital\u2019s Cygnus making resupply runs to the orbital outpost, an arrangement fostered by NASA\u2019s Commercial Orbital Transportation Services (COTS) contract.<\/p>\n
SpaceX are still waiting to hear confirmation that they will be able to accelerate their original demonstration schedule, by way of combining flight 2 and 3 of their Dragon demonstrations, while Orbital\u2019s Cygnus is expected to debut early next year for what will be only one demonstration flight.<\/p>\n

A key milestone for Orbital\u2019s drive towards ISS resupply missions was the arrival of the PCM at its Wallops launch site, following a transatlantic flight from its manufacturing location in Italy.<\/p>\nThe PCM was unloaded from the Antonov An-124 transport aircraft in its specialized shipping container, prior to being transported to NASA\u2019s H-100 payload processing facility, where it will be uncrated later this week and prepared for integration with Orbital\u2019s spacecraft service module.<\/p>\n
Thales Alenia Space will provide Orbital with eight more pressurized modules for cargo missions to the ISS. The first PCM will be followed by three more units in \u201cstandard\u201d configuration, capable of transporting up to 2,000 kg of cargo each, along with five \u201cenhanced\u201d configuration units, boosting payload capacity to 2,700 kg.<\/p>\n

The Cygnus vehicle consists of an advanced service module and a PCM. The service module incorporates avionics, power and propulsion systems from Orbital\u2019s flight-proven LEOStar and GEOStar satellite product lines.<\/p>\nBased on NASA\u2019s requirements, it will deliver crew supplies, scientific experiments and equipment, spares parts and other essential cargo to the ISS.<\/p>\n
The Cygnus PCM developed via Thales Alenia Space\u2019s experience with the ISS, as seen with their MPLM (Multi-purpose Logistics Module) which rode numerous times with Shuttle to the orbital outpost \u2013 which was built by the company on behalf of the Italian space agency for NASA.<\/p>\n

The Italian-based company are also a major player with the ATV (Automated Transfer Vehicle) Cargo Carrier, built for the European Space Agency (ESA). Thales Alenia Space was also a key player in the Columbus laboratory and prime contractor for Node 2, Node 3 and the Cupola \u2013 all now on orbit with the ISS.<\/p>\n
Together, the PCM and the service module will form the first operational Cygnus that will be launched to the ISS to carry out a demonstration mission, which follows a test flight of the Taurus II launch vehicle at the end of this year.<\/p>\n

Taurus II is a two-stage launch vehicle designed for medium-class payloads weighing up to 5750 kg. The vehicle\u2019s system utilizes identical management approaches, engineering standards, production and test processes common to Orbital\u2019s family of small-class Pegasus, Taurus, and Minotaur launch vehicles.<\/p>\nTaurus II incorporates both solid and liquid stages which meet medium-class mission requirements for variety of low inclination low-Earth and sun synchronous orbits and interplanetary trajectories.<\/p>\n
The vehicle sports a 3.9 meter fairing to accommodates large payloads such as the Cygnus, while streamlined vehicle\/payload integration and testing via simplified interfaces reduce time from encapsulation to lift-off.<\/p>\n
Taurus II is capable of launching single and multiple payloads from the Wallops Flight Facility (WFF), although it is compatible with the Western Range at Vandenberg Air Force Base (VAFB), the Eastern Range at Cape Canaveral Air Force Station (CCAFS) and Kodiak Launch Complex (KLC).<\/p>\n

Following the Taurus II test flight and the Cygnus COTS demonstration mission, Orbital will press immediately forward into their Commercial Resupply Services (CRS) contract, with the first CRS flight scheduled to take place in the second quarter of 2012.<\/p>\n\u201cThe arrival of the first pressurized cargo module at Wallops is an important milestone for the Cygnus program, signifying that we are making great progress toward carrying out the COTS demonstration mission early next year,\u201d said Mr. Frank DeMauro, Orbital\u2019s Cygnus Program Manager.<\/p>\n
\u201cWith the first fully-assembled service module currently in testing at our Dulles, Virginia satellite design and production facilities, it won\u2019t be too long before both of the major elements are united at Wallops for final system integration, followed by integration with the Taurus II rocket that will launch Cygnus to the International Space Station.\u201d<\/p>\n

The deal to carry out ISS resupply flights \u2013 under the $1.9 billion CRS contract \u2013 encompasses eight missions between 2012 and 2015 carrying approximately 20,000 kg of cargo to the ISS.<\/p>\n\u201cThis is one more important step in our partnership with U.S. private industry to build safe, reliable and cost effective cargo transportation systems,\u201d said Philip McAlister, acting director of commercial spaceflight development at NASA Headquarters in Washington. \u201cWe are pleased that Orbital has made this accomplishment and look forward to the company flying the Cygnus spacecraft in 2012.\u201d<\/p>\n
The debut CRS runs by Dragon and Cygnus will provide the United States with an ability to custom design payloads required by the ISS, as full utilization takes hold on orbit.<\/p>\n
It will also mark the first tangible step towards the US regaining its domestic human space flight capability, with several manned vehicles currently being designed via the Commercial Crew Development (CCDev) contracts, prior to a NASA decision on which vehicles it will buy services from to launch its astronauts to the ISS.<\/p>\n
