Вот те раз, а как же CUCU? Видимо Орбиталу не понравилось что-то в предложениях SpaceX.

ЦитатаCygnus update
« on: Today at 05:50 AM »
A quick status on Cygnus.

Passed ISS Phase II safety review.

Wrapped up the CDR series (which began Nov 2009).

First Pressurized Cargo Module assembly underway in Torino - basic welded structure completed.

Will provide pictures as I get them.

We plan to have a full-scale mockup of a Cygnus spacecraft (Service Module plus a Pressurized Cargo Module) at the National Space Symposium at the Broadmore in Colorado Springs which starts Moday April 12 (by the way, we're sponsoring the opening fireworks...)

If you happen to be at the NSS, you can't miss it: it will be by the lake, to the right of the bridge that crosses the lake.

ЦитатаCygnus Advanced Maneuvering Spacecraft

Cargo Delivery Spacecraft for the International Space Station (ISS)

The Cygnus advanced maneuvering spacecraft is being developed by Orbital to demonstrate cargo delivery services under a NASA Commercial Orbital Transportation Services (COTS) agreement. In addition to the COTS development and demonstration program, Orbital will utilize the Cygnus to perform the ISS resupply fights under the Commercial Resupply Service (CRS) contract. This NASA contract authorizes eight missions between 2011 and 2015 carrying approximately 20,000 kg of cargo to the ISS as well as disposal of ISS waste.
The Cygnus system is a low-risk design incorporating elements drawn from Orbital and its partners' existing, fight-proven spacecraft technologies. Cygnus consists of a common service module and a pressurized cargo module. Cygnus will carry crew supplies, spares and scientifc experiments to the ISS.
The service module incorporates avionics systems from our Dawn interplanetary spacecraft plus propulsion and power system from Orbital's fight-proven STAR GEO communications satellites.
The pressurized cargo module is based the on the Multi-Purpose Logistics Module (MPLM), developed by Thales Alenia Space for NASA.

Elias said Orbital could develop a Cygnus variant capable of returning space station cargo safely to Earth within two years if asked to do so by NASA. He said that vehicle would have to be equipped with heat shielding and parachutes, and that the extra weight of those items would reduce by half the amount of cargo it could deliver to the space station.

"You don't use that configuration unless you absolutely, positively need that return cargo," Elias said. He said a company analysis of the type of return cargo that would be valuable enough for NASA to give up 1,000 kilograms of cargo-to-station delivery capacity identified only one item: the suits astronauts wear during spacewalks.

The re-entry module under discussion is not designed to carry astronauts to and from the space station. Orbital will not be able to provide information on the cost and capability of a commercial crew vehicle until the company knows how NASA would structure the procurement of such a spacecraft and what the requirements would be, Elias said.

ЦитатаMajor Software Integration Milestone Completed, PCM Production in Full Gear[/size].

September 2010.

Over the course of three weeks in August and early September, the NASA/Orbital Joint Avionics Test #2 (JT2) was held at the NASA Station Development and Integration Laboratory (SDIL) near Johnson Space Center in Houston, Texas. This early integration test of the International Space Station (ISS) and Cygnus flight software involved personnel from NASA, Orbital, Boeing and Mitsubishi Electric Company, and Orbital's processor-in-the-loop testbed (pictured below left).

The purpose of the test was to ensure that Cygnus and ISS flight software were capable of communicating via both berthed and proximity communications system links. The primary objective of the test was to demonstrate basic command and telemetry data routing between the ISS and Cygnus flight software. A number of secondary objectives were included as well.

During the course of the test, Orbital engineers were able to fully demonstrate 16 out of the 21 design verification objectives required to satisfy NASA requirements. This was a remarkable accomplishment given that this was the first time the NASA, JAXA, and Orbital hardware and software had been physically integrated into a working system. Orbital will return to the SDIL in November 2010 with final integration testing slated for March 2011.

Meanwhile, at Thales/Alenia Space in Turino Italy, production of the Pressurized Cargo Modules (PCM) continues at a robust pace as evidenced by the image below right of two PCMs on the production floor. Structure welding on the last standard configuration PCM was completed in late September. Delivery of the first PCM to Orbital is currently planned for Q1 2011.

Orbital Warns Investors Prolonged U.S. Budget Battle Will Harm 2011 Earnings[/size]
By Peter B. de Selding

    PARIS -- Satellite and launch-vehicle manufacturer Orbital Sciences Corp. on Oct. 21 reported double-digit increases in revenue, operating income and net profit but said its 2011 financial performance could drop by 6 percent to 8 percent from expected levels if the U.S. government does not conclude a final 2011 budget before spring.

    The Dulles, Va.-based company said its biggest ongoing investment -- development of the Taurus 2 medium-lift rocket and the Cygnus cargo vehicle it will launch to the international space station -- has encountered more delays. Its inaugural launch from Wallops Island, Va., is now set for between July and September.

    Whether that flight serves only to demonstrate Taurus 2's abilities or also carries the Cygnus freighter will depend on whether the U.S. Congress appropriates the money for a rocket-only flight when it finally enacts NASA's budget for 2011. If that money, which would come out of the additional $300 million NASA has requested for its Commercial Orbital Transportation Services program, is forthcoming, a successful Taurus 2-only demonstration could be followed, about three months later, with a Taurus 2 Cygnus launch to the space station.

ЦитатаOrbital Opens Mission Operations Center for NASA's Commerical Cargo Services Program.

-- Control Center for International Space Station Cargo Resupply Missions Now Fully Functional at Company's Dulles, Virginia Facilities --

-- NASA Administrator Charles Bolden On Hand for Opening Ceremony --

Orbital Sciences Corporation announced that it held a formal dedication ceremony earlier today to mark the completion of a new facility that will serve as the Mission Operations Center (MOC) for the company's cargo logistics missions to the International Space Station (ISS) for NASA that begin in 2011. The ribbon-cutting event was attended by NASA's Administrator Charles F. Bolden, Jr. and several other senior representatives of the space agency.

"After nearly three years of developing the Taurus II rocket and the Cygnus spacecraft, we are less than a year away from our first scheduled launch to the ISS," said Mr. David W. Thompson, Orbital's Chairman and Chief Executive Officer. "The Mission Operations Center dedicated to the COTS and CRS programs is a critical element in our overall system architecture, providing us with robust command and control systems for the upcoming missions, as well as providing direct connectivity capabilities with our Houston-based customers at NASA's Johnson Space Center."

While at Orbital's Dulles, VA facilities, the NASA delegation viewed a full-scale mock-up of the Cygnus spacecraft, which will carry essential cargo to the ISS following its launch aboard Orbital's Taurus II rocket from the Wallops Flight Facility in Eastern Virginia. In addition, Administrator Bolden and the other NASA officials toured Orbital's Mission Control Complex, which includes three additional MOCs that support the company's extensive manifest of other satellite and launch vehicle missions. The delegation also visited Orbital's satellite manufacturing facility, at which four NASA scientific satellites - Glory, NuSTAR, OCO-2 and GEMS - are in various stages of design, production and testing by the company's technical operations team.

COTS and CRS Overview

Under a 2008 cooperative research and development agreement with NASA in its Commercial Orbital Transportation Services (COTS) program, Orbital is developing a new autonomous spacecraft and related launch vehicle and ground infrastructure for the delivery of cargo and supplies to the ISS. The COTS program encompasses the full-scale development and flight demonstration of a commercial cargo delivery system that consists of a Taurus II medium-class space launch vehicle, a Cygnus cargo logistics spacecraft, and ground-based command and control systems.

With the award of the $1.9 billion Commercial Resupply Services (CRS) contract in late 2008, NASA selected Orbital to carry out eight cargo logistics missions to the ISS from 2011 to 2015. For NASA, CRS will provide an automated cargo delivery service, produced and operated in the United States, for ISS logistics support. The new system will complement Russian, European and Japanese ISS cargo vehicles.

ЦитатаWe just held a cargo loading exercise for the PCM in Torino.  I don't know which crew members supported that, I'll report as soon as I find out.  Here are two pictures of the inside of the loaded PCM and a team picture that also shows the "sting" used to carry the load items inside the PCM for stowage.

Let's just hope the Longshoremen's Union doesn't find out we're loading cargo without a union card; we may have a grievance on our hands...
