Этот вариант Cygnusа может везти 2000 кг груза. Фактически в него загружено будет 560 + 171 = 731 кг (по ссылке Salo о доставке груза от НАСА вверху). Информации, что первый полет включает в себя большое количество дополнительных маневров на орбите, как было с Dragonом, на которые может потребоваться большое количество дополнительного топлива, не нашел. Симулятор в первом полете вроде как был на полную загрузку, так что тема недостаточной мощности Антареса вряд ли актуальна. Вопрос - есть какая-то информация, почему НАСА не загружает первый полет на полную каким-то дешевым, некритическим грузом, который будет не жалко потерять, но будет полезно иметь?

В первых двух полётах используется на второй ступени Cаstor-30A. ПН судя по A-one составляет 3800 кг.
Во время CRS-1 (Orb-1) и CRS-2 (Orb-2) будет использоваться Саstor-30B и ПН составит 4600 кг.
Начиная с CRS-3 (Orb-3) будет использоваться Саstor-30XL и ПН составит 5100 кг.

Соответственно и масса грузов доставляемых на МКС будет расти.

ЦитироватьCygnus Spacecraft Fueled at Wallops Flight Facility

April 2013

– While all eyes have been on Antares in the recent weeks, our Cygnus spacecraft has achieved many significant firsts as it prepares for its maiden voyage to the International Space Station. After initial cargo installation at Wallops Flight Facility building H-100 and the first-time mating of the Cygnus Service and Cargo Modules, Cygnus completed its next milestone by completing its Launch-Site Integrated Systems Test and its transfer fr om the Wallops Main Base to the Wallops Fueling Facility, on Wallops Island, just north of the Antares launch site.

For the transfer, the Cygnus was loaded into the Cygnus Vertical Carrier (CVC). Because Cygnus was using the main road through the town of Atlantic, Virginia, the transfer was conducted at midnight, when road traffic would be minimal. Local residents did come out to watch Cygnus' historic trip, which gave a festive air to a technical activity. Total travel time was a little less than 3 hours, with speeds averaging between five and seven miles per hour. Cygnus was delivered to the hypergolic fueling facility at building V-55, early on the morning of April 13th, where preparations immediately began for the fueling.

Because Cygnus uses hypergolic propellants, Orbital loads the fuel on one day, and then the oxidizer several days later. Since both fuel an oxidizer are poisonous, our Orbital personnel must wear special personal protective equipment while working with the propellants in the event of a leak in the facility. In the following pictures, Orbital personnel are "suited up" in SCAPE suits for the fuel loading. SCAPE stands for "Self-Contained Atmospheric Protective Ensemble," and the suits look very much like an astronaut's space suit. Fueling is monitored by engineering and safety personnel in building V-50, located nearby to V-55. Personnel in V-50 used a series of closed circuit TV cameras to monitor activities during the propellant loading process. Fuel loading occurred on April 15th, with oxidizer loading occurring on April 19th. Now fully fueled, Cygnus will be returned to the CVC for transfer from V-55 to the Horizontal Integration Facility, wh ere it will wait for integration onto the Antares for the COTS Demonstration mission to the space station.

Забавно, что даже если разница в ПН между текущей версией и CRS-1/2 составляет 800 кг, а Cygnus для CRS-1/2 должен уметь возить 2 т. груза, то в это полет все равно недогрузили более 400 кг, так как логично предположить, что доставляемый груз в этом полете тогда должен быть 1200 кг, а загружено будет 781.

ЦитироватьAfter Antares test launch, Orbital aims for space station
BY STEPHEN CLARK
SPACEFLIGHT NOW
Posted: April 26, 2013

Buoyed by a flawless test launch of the Antares rocket, the heavy-lifting part of its commercial cargo resupply system for the International Space Station, Orbital Sciences Corp. has its eye on a summer demonstration flight of the company's Cygnus resupply freighter.

The next flight, scheduled to launch in June or July, will go all the way to the space station and offers a steeper technical challenge for the Virginia-based aerospace contractor than the successful launch of its first Antares rocket Sunday.

"I'm not going to hold my breath any less on the next one than I did on this one," said Frank Culbertson, executive vice president and general manager of Orbital's advanced programs group. "Every launch is a challenge, and you want to make sure that it's all done right."

Sunday's flight was the culmination of a six-year, $300 million effort to design, build and test the Antares booster, which can loft medium-class satellites into orbit and is contracted by NASA to launch nine more times on cargo deliveries to the space station.

It also broke in a new $140 million launch pad at NASA's Wallops Flight Facility on Virginia's Eastern Shore. Launch pad 0A is owned by Mid-Atlantic Regional Spaceport and was mostly funded by the Virginia Commercial Space Flight Authority.

"Early results of the engineering analysis indicate that the vehicle's all-important first stage system, including its twin liquid rocket engines, performed exactly as expected, as did other vehicle systems as well as the launch complex's propellant and pressurization equipment," said David Thompson, Orbital's chairman, president and CEO.

Culbertson said the success of Antares permits the company to move on to the next phase of its $288 million agreement with NASA, which is how the U.S. government finances development of the Antares rocket and Cygnus spacecraft in partnership with Orbital's own capital.

"All of that demonstrated that when we do this again, we know how to make this happen and we'll get that payload - the Cygnus - into orbit and on its way to the International Space Station, so that it can continue its mission and we can provide the cargo, the experiments, the clothing and food that they need to sustain and extend their mission."

Already fueled and loaded with cargo, the first Cygnus spacecraft will be bolted to the second Antares rocket ahead of launch fr om Wallops Island, Va.

Sunday's Antares test flight only sent a dummy payload into orbit.

Engineers installed cargo bags into the spacecraft's cylindrical pressurized module, built by Thales Alenia Space of Italy, and pumped maneuvering propellant the vehicle's service module, manufactured by Orbital Sciences. The spacecraft will be kept in storage until it is ready for attachment to the Antares rocket at the launch base's horizontal integration facility, according to Culbertson.

"It's ready to be transferred into the horizontal integration facility, and as soon as the rocket is ready to receive it, we will integrate the two together and it will be ready to roll out to the pad some time this summer - probably late June or early July," Culbertson said. "So we will be on track for delivery, assuming the space station schedule can accommodate us, and we don't run into any unforeseen problems."

In March, technicians packed 1,235 pounds of cargo into the craft's Italian-built main cabin, then engineers mated the pressurized compartment to the Cygnus service module. Earlier this month, workers filled the spaceship's tanks with propellant.

"The spacecraft will not be the long pole in getting to the pad," Culbertson said. "It will be just evaluating the pad condition to see what we have to do to refurbish it, if anything, and then getting the next core completely assembled with its engines, the second stage, and get the fairing in here so we can assemble and attach the spacecraft to the front end, and then roll it out."

Workers will add some additional cargo, including fresh food, into the Cygnus spacecraft before it rolls to the launch pad.

The Cygnus freighter's cargo section is based on the multi-purpose logistics modules used by NASA to ferry supplies to and from the space station in the space shuttle era. Orbital devised the Cygnus service module using a design proven on the company's geostationary communications satellites.

While Orbital paid for the development of the Antares rocket with private financing, the company funded work on Cygnus jointly with NASA. Orbital started working on the Antares rocket in early 2007, and the firm won public funding from NASA in February 2008.

NASA tapped Orbital and SpaceX, which has accomplished its space station test flights, for operational resupply missions to the space station in December 2008. Orbital's contract is worth $1.9 billion and covers eight flights through 2016.

The U.S. space agency turned to the commercial sector to replace some of the cargo-carrying capacity lost with the space shuttle's retirement.

Orbital's first four operational Cygnus missions will each carry up to 4,400 pounds of equipment, food and experiments to the space station. Orbital and Thales plan to introduce a larger cargo module for flights in the second half of the contract, raising the Cygnus capacity to nearly 6,000 pounds per flight.

Unlike SpaceX's Dragon spaceship, which can return hardware to Earth intact, the Cygnus will dispose of the space station's trash in a fiery re-entry back into the atmosphere, similar to most of the station's supply freighters.

One big advantage of the Cygnus is its ability to carry more volume than Dragon, according to NASA.

With most of the hardware for the next mission already at the Wallops launch base, engineers will complete pending safety reviews for NASA and space station partners to approve the approach of the Cygnus spacecraft within the outpost's vicinity.

"What's left to finish up is the verification of the final safety review packages to make sure it is compliant with the visiting vehicle requirements that we establish," said Alan Lindenmoyer, manager of NASA's Commercial Orbital Transportation Services program, which oversees the cost-sharing development agreement for the Orbital Sciences cargo resupply system.

"Once those verifications are complete, we'll go into a final review of flight readiness status," Lindenmoyer said.

Meanwhile, NASA and Orbital will continue joint testing of the Cygnus spacecraft's flight software.

"There has already been a great deal of joint testing done with the software simulating a mission, and that's gone very well," Lindenmoyer said.

The joint tests ensure the Cygnus software will function in concert with the space station.

"Software is always one of the most challenging things in any development," said Frank DeMauro, Orbital's Cygnus program manager.

Culbertson said the Antares and Cygnus teams will be ready when called upon.

"When we do this with a Cygnus spacecraft on the front end, and we have cargo to deliver, we're not going to have the luxury of a two-hour window," Culbertson said, referring to the length of the launch window on the Antares test flight. "We're going to have anywhere from five to zero minutes, so we're going to have to get it right the first time."

It will take three-to-five days for the Cygnus spacecraft to each the space station. The exact timing of the mission partially depends on finding an opening in the space station's busy manifest, which this summer includes the arrivals of European, Russian and Japanese resupply ships, plus a series of spacewalks.

"We'll be at a certain level of nervousness all the way to main engine cutoff and then to orbit insertion," Culbertson said. "But on that one, of course, we will have the additional challenge of making sure the Cygnus is actually in orbit and that it deploys its solar arrays, it has its own power, and then it can start its rendezvous maneuvers to get to the station, which will take about three-to-five days."

Along the way, controllers at Orbital Sciences headquarters in Dulles, Va., will put the Cygnus spacecraft through predefined tests, demos and health checks. NASA must sign off on the results of the tests before the craft can get close to the space station.

Using automatic on-board navigation aids, the Cygnus spacecraft will fly itself to a point about 30 feet below the space station, wh ere it will be grasped with the lab's robotic arm and moved to a parking spot on the complex for a stay of up to a month.

"We won't relax for quite a while on that one until we're actually grappled, berthed to the station and the hatch is opened," Culbertson said. "Even then, we'll still want to make sure everything goes right, but that will be a major achievement."

ЦитироватьNCESSE's SSEP Mission 3 to ISS Experiment Payload on Historic Flight of Orbital Sciences Cygnus, launching from MARS, June 2013
Published on May 3, 2013 by Jeff Goldstein in News

The National Center for Earth and Space Science Education (NCESSE), and the Arthur C. Clarke Institute for Space Education are proud to announce that Student Spaceflight Experiments Program (SSEP) Mission 3 to ISS experiments will be on the first flight of Orbital Sciences Cygnus to dock with the International Space Station. We thought, though, that we'd share this historic milestone through a backstory. (Spoiler alert – this is a long post.)

This SSEP National Blog is used as a public information channel for the SSEP, providing general program news for anyone interested in following along, including students, teachers, a few hundred local and national partner organizations, and the interested public. But behind the scenes, each SSEP flight opportunity is associated with a network of participating communities, and all educational leadership and SSEP teachers in those communities are on an email distribution listserve. The flight-specific listserve is how day-to-day information is routed to the communities, to their grade 5-14 student researcher teams during the experiment design and proposal phase, and to the student flight experiment teams during the flight operations phase.

To provide a sense of the level of communication – right now and into the future – there are currently 17 Mission 3 to ISS communities in the midst of flight operations to orbit (over 7,000 students were fully engaged in microgravity experiment design and over 1,400 microgravity experiment proposals were submitted by student teams); 11 Mission 4 to ISS communities are winding up the proposal phase, with their flight experiments to be sel ected by the end of May, 2013; and NCESSE and the Clarke Institute are about to announce Mission 5 to ISS, with operations beginning September 2013. SSEP is about to turn 3 years old in June 2013. It is therefore remarkable that the SEVENTH flight opportunity to orbit  - Mission 5 to ISS – is about to be announced. Equally remarkable – 14 existing SSEP communities have already submitted formal Implementation Plans for Mission 5, reflecting communities starting their second, third, fourth, and even fifth SSEP flight opportunity. This is what sustainable STEM education looks like.

To provide a sense of SSEP program operations behind the scenes, we wanted to share a communique that was issued yesterday via the Mission 3 to ISS listserve. It provides a remarkable window on real spaceflight, what teamwork looks like, and the decisions that student flight teams need to make as real microgravity researchers. And it provides a window on the historic nature of what we are all doing together.

An important note for an understanding of the communique: The 17 Mission 3 to ISS flight experiment teams had a choice to fly their experiment to ISS aboard Soyuz 35S launching on May 28, 2013, or to fly on SpaceX-3 launching in the Fall. The Soyuz 35S flight was sooner, but did not provide refrigeration up to ISS, and the stay aboard ISS was a very long 15 weeks. The SpaceX-3 flight would be next academic year, but offered refrigeration up to ISS, and a more typical, approximately 6-week duration on ISS. Of the 17 flight teams, 5 decided to fly on Soyuz 35S. An additional two SSEP experiments were to fly on Soyuz 35S, a re-flight for a Mission 1 experiment and a re-flight for a Mission 2 experiment, due to mini-lab activation failure.

 

May 2, 2013, 8:40 am ET
SUBJECT: URGENT to the 7 SSEP Mission 3 Flight Teams on Soyuz 35s – Major Flight Change

To all 7 SSEP flight experiment teams that were scheduled to fly on Soyuz 35S on May 28, 2013 -

We unfortunately have a major change in ferry flight operations to ISS for the SSEP Mission 3 experiments payload. We received the notification below from NanoRacks on Tuesday, April 30, 2013, at 5:30 PM ET. Yesterday we were in communication with NanoRacks and fully assessed the situation. With this email, we are now forwarding you the NanoRacks notification together with NCESSE notes on impact, and immediate actions required by your student flight team. All Mission 3 community Program Directors for the 5 affected Mission 3 experiments, and all Teacher Facilitators for the 5 Mission 3 experiments, the Mission 1 re-flight experiment, and the the Mission 2 re-flight experiment are urged to rapidly communicate this information to their student flight teams, and respond rapidly to our request for information below.

Dr. Jeff Goldstein
SSEP National Program Director

From NanoRacks-

NanoRacks has been working with the Russians and NASA for the upcoming launch of the Mission 3 experiment mini-lab payload on Soyuz 35S, which was scheduled to lift off from Kazakhstan on May 28, 2013. Understanding the complexity of meeting this launch date in Kazakhstan via Russia, we asked [SSEP Falcon 1] flight experiment teams to ship their mini-labs to NanoRacks in Houston by April 24, six weeks in advance of launch.

We unfortunately must report that an unforeseen payload approval issue has come up last minute that makes launch of the payload on Soyuz 35S untenable. Unforeseen last minute requests by our Russian colleagues due to custom considerations to import biologicals has halted the payload onboarding process, and the additional requirements just put forward to NanoRacks make it impossible for us to be comfortable that we would have met the requirements in time to fly on Soyuz 35S.

Therefore, rather than gamble on acceptance, we accepted the offer from NASA to fly on the Orbital Sciences D-1 Cygnus mission scheduled to launch on June 15, 2013 out of NASA Wallops Flight Facility, Wallops Island, Virginia. We have to say this is NASA going above and beyond in support of NanoRacks, NCESSE, and SSEP.

We understand the transition to Orbital may lead to frustration on the part of the flight teams, given that the launch is pushed off, but this is the nature of the space business which is still a frontier. It is not easy. It is hard. Working together as a team we can make this happen, as we have for the last 4 SSEP flight missions.

We understand that some of the 7 experiments might be perishable, and may need to be resubmitted. If this is the case work though NCESSE, and we will all figure out a fix.

We also understand that pushing the flight beyond May 28 can pose real scheduling problems for some flight teams, given they will need to conduct ground truth experiments possibly after the end of the academic year. Again, this is the nature of the real space business, and it is what professional microgravity researchers must contend with for their flight operations. If pushing flight operations poses a problem for a flight team, again, work though NCESSE and let's see if we can find a work-around.

We wish that we did not have to report this problem, but please know we are always working on behalf of all NCESSE communities participating in SSEP to provide unique and real access to orbit for student researchers.

 

I. IMPORTANT INFORMATION FROM NCESSE IN RESPONSE TO NANORACKS NOTIFICATION

1. The flight to ISS is now scheduled to launch on Cygnus on June 15, 2013, 2.5 weeks later than the original Soyuz 35S flight on May 28, 2013. However, the ferry flight back to Earth, on Soyuz 34S, remains unchanged, with an un-docking currently scheduled for September 11, 2013. (Note, as is always the case, these launch and landing dates are indeed subject to change by NASA.) This means that the time on orbit for the experiments is 2.5 weeks shorter than planned – which might be a good thing since the originally planned 15-week duration on ISS was significantly longer than the typical SSEP flight opportunity which has payload on orbit for about 6 weeks. This was one of the key considerations when each Mission 3 flight team was deciding on going with the Soyuz 35S or SpaceX-3 opportunity.

2. Refrigeration: as with Soyuz 35S, there will be no means to refrigerate the payload from the time NASA hands over the payload to Orbital Sciences through delivery to ISS. So nothing has changed in terms of thermal control.

3. Background – This Is A Historic Opportunity
Recall that in the post-Space Shuttle era, NASA is looking to commercial (private) companies to step to the plate and provide service for cargo and crew to low Earth orbit. This is heralding in a bold new era of human spaceflight – commercial spaceflight – much like Charles Lindbergh's transatlantic flight in1927 launched commercial aviation.

Orbital Sciences and SpaceX are the two commercial companies right out of the gate, and both are under contract with NASA to first fly payloads to ISS, then crew. For SpaceX, it is the Dragon spacecraft atop its Falcon rocket, and which launches from Cape Canaveral Air Force Station, next to Kennedy Space Center in Florida. For Orbital Sciences, it is the Cygnus spacecraft atop its Antares rocket, launching out of the MARS – the Mid-Atlantic Regional Space Port near NASA's Wallops Flight Facility, Wallops Island, Virginia (see http://www.marsspaceport.com/). MARS is remarkable in that it is now operational, and represents the near future – spaceports opening across the nation, indeed the world, for commercial sub-orbital and orbital flights, much like commercial airports were built world-wide in the early 20th century to service commercial aviation.

SSEP saw the end of the Shuttle era, with the first two SSEP flight experiment payloads – payloads Eagle and Intrepid – on the final flight of Space Shuttle Endeavour (STS-134) and on the final flight of the United States Space Shuttle program – the flight of Atlantis (STS-135). SSEP was also there to herald in this new era of on-orbit commercial spaceflight. The SSEP Mission 1 to ISS Aquarius payload was carried aboard the first SpaceX Dragon flight to berth with ISS – the very first time a commercial (private) vehicle docked with ISS. It was historic. And the Aquarius payload was the only research payload aboard Dragon. Indeed, SSEP itself is historic – the first U.S. National STEM education program that provides access to orbit for pre-college student payloads – and which is a COMMERCIAL space venture.

Orbital Sciences conducted its first successful demonstration flight for the Antares rocket on April 21, 2013. It was a launch-to-orbit flight but with no berthing with ISS. (SpaceX Dragon also had one of these demonstration flights to orbit with no berthing.) Because of this recent success, Orbital Science and NASA have rapidly scheduled the first flight for Cygnus to berth with ISS, with a launch on June 15, 2013. Given the issues with Soyuz 35S encountered by NanoRacks, NASA has placed the payload of SSEP Mission 3 experiments aboard this historic flight of Cygnus. SSEP – and the student flight teams flying experiments aboard Cygnus – are again part of history.

100 years from now, historians will point to what we are living through as the moment in history when the human race truly became a spacefaring species. So while this change in flight operations is likely frustrating, it is a remarkable teachable moment for all of us to savor.

To help see the historic import, here are SEEP National Blog posts I wrote to capture the moment when we first launched on SpaceX Dragon:
http://ssep.ncesse.org/2012/02/ssep-mission-1-student-researchers-to-be-part-of-history-aquarius-experiments-payload-officially-on-spacex-dragon-to-iss/

4. Given that the launch will now take place in the U.S., NCESSE is willing to explore with MARS staff whether they would host delegations from communities coming down for the launch. But we only want to pursue this – and this would have to be done very quickly – if communities are interested in sending delegations to the launch site. This is clearly last minute, and there are hurdles to traveling to MARS, e.g., no airport very close.

 

II. URGENT REQUEST FOR INFORMATION FR OM STUDENT FLIGHT TEAMS WITH EXPERIMENTS ABOARD CYGNUS

Given the significant change in flight operations, all student flight teams for the 7 flight experiments are requested to immediately assess impact on their flight experiment and report out answers for the following questions to your SSEP Flight Ops Manager, Stacy Hamel: stacyhamel@ncesse.org

PLEASE RESPOND TO STACY WITH YOUR ANSWERS BY MONDAY MAY 5, 2013, 5:00 PM EDT.

1. Your experiment will not get to ISS until 2.5 weeks later than planned
QUESTION: Are your fluids/solids perishable to the point that the change requires you to send a new mini-lab containing new fluids and solids? (We believe this is likely not the case, given that this was a very long duration mission to begin with – 15 weeks on ISS – and likely only experiments that could be held in stasis for a long period would have been put on Soyuz 35S, as opposed to the payload flying on SpaceX-3 in the Fall with duration on ISS of 6 weeks.

2. Crew Handling
QUESTION: given the shorter duration on orbit, do you need to change your Crew Handling directions? Recall that your Crew Handling Directions are given in days relative to Arrival (A), and Departure (D). Refer to the Mission 3 Mini-Lab Operations page.

3. Conducting Your Ground Truth Experiments
QUESTION: Does the new flight schedule adversely impact your ability to conduct your Ground Truth Experiments at the same time as your on-orbit experiment is conducted? (We beleive this is also likely not the case. Even though the new launch date may be near to, or after, the end of the academic year, on-orbit operations were going to continue through September 2013 anyway. So all teams that chose to put their experiment on Soyuz 35S must have already planned their ground truth activity throughout the summer.)

Important reminder: remember that there will be a Mission 3 Flight Operations Log on the SSEP website (we had directed you familiarize yourself with the Mission 2 Log). The Log will detail every astronaut interaction with every experiment, so each team can replicate in their ground truth what is happening with their experiment on orbit. This allows you to compare the ground truth to the flight experiment when harvesting and analyzing your samples on return to Earth, which is likely a vital activity for experiment success. NCESSE assumes that all flight teams are prepared to simultaneously conduct ground truths with their on-orbit experiments using the Log.

4. Other Adverse Considerations
QUESTION: are there any other adverse impacts on your experiment due to the flight change?

5. Is there interest in your community sending a delegation to the launch? If yes, we need to know ASAP, and this includes total in delegation, and a breakdown of attendees by SSEP student researchers, teachers/administrators, and family members.

Best wishes,
Real spaceflight all the time,

Jeff

ЦитироватьAntares Post-Flight Analysis Results - Flawless Launch Confirmed; Company Updates COTS Demonstration Mission Schedule

May 2013
...
With the Antares Test Flight successfully completed, Orbital's Antares and Cygnus teams are now focused on the Demonstration Mission to the International Space Station (ISS), the final milestone in the COTS joint program with NASA. Orbital currently expects to be ready to carry out the Demonstration Mission in August. Orbital is swapping out one first stage AJ26 main engine for another unit that is already fully tested in order to further inspect and confirm a seal is functioning properly. The company expects the engine change-out process to add about three to four weeks to the schedule. In addition, missions to the ISS must be carefully scheduled with NASA to fit into the pre-planned traffic pattern at the orbiting laboratory. A Japanese cargo ship, the HTV, is also scheduled for a mission to the ISS in August. If the HTV schedule slips, Orbital expects to be ready to go in August. If the HTV holds its schedule, Orbital's Demonstration Mission could be planned for September.

01:4507.05.2013
МОСКВА, 7 мая — РИА Новости. Первый полет частного космического грузовика Cygnus, ранее планировавшийся на начало лета, состоится не ранее сентября — такое решение приняла компания-разработчик Orbital Sciences в связи с необходимостью замены одного из двигателей ракеты-носителя.

В конце апреля ракета "Антарес" после старта с космодрома на острове Уоллопс успешно вывела на орбиту масс-габаритный макет корабля Cygnus ("Лебедь"). "За две недели после успешного дебютного полета... специалисты проанализировали собранный объем данных... И пришли к выводу, что первая и вторая ступени ракеты, сбросы обтекателя и отделение полезной нагрузки прошли так, как планировалось", — говорится в сообщении компании.

Однако компания решила заменить один из двигателей первой ступени ракеты "Антарес", которая будет выводить корабль, на полностью проверенный и протестированный, чтобы избежать проблем с уплотнениями, зафиксированных ранее во время огневых испытаний. Поэтому ракета будет готова к старту не в июне-июле, а в августе.

В августе запуск корабля к МКС невозможен из-за "конфликта расписаний" с японским кораблем HTV, который отправится на орбиту в том же месяце. Если запуск HTV будет отложен, то Cygnus может полететь раньше, если нет — запуск может состояться в сентябре.

Orbital Sciences наряду с компанией SpaceX в 2008 году получила от НАСА контракты по доставке грузов на МКС — CRS-контракты (Commercial Resupply Services), на долю Orbital Sciences пришлось восемь рейсов. Конкурент компании, SpaceX, 1 марта запустила второй плановый грузовой рейс на корабле Dragon к Международной космической станции. В отличие от корабля Dragon, Cygnus не имеет возвращаемой капсулы и сможет доставлять грузы (от 2 до 2,7 тонны) только в один конец — на МКС, как это делают сейчас российские, европейские и японские грузовые корабли.

 Новый экипаж МКС, возможно, встретит на орбите первый грузовик Cygnus

Участники новой экспедиции на МКС, которые отправятся в космос в конце мая, до осени встретят на станции множество космических грузовиков, в том числе, возможно, первый корабль Cygnus, созданный корпорацией Orbital Sciences.
"Мы будем принимать большое количество кораблей, (европейский грузовой корабль) ATV — в июне, "Прогресс", затем (японский корабль) HTV будет в августе стыковаться к американскому сегменту... И затем, я надеюсь, прибудет корабль, созданный корпорацией Orbital Sciences", — сказала бортинженер МКС, астронавт НАСА Карен Найберг на пресс-конференции нового экипажа в Звездном городке.
Она отметила, что прошла подготовку по обеспечению стыковки корабля Cygnus со станцией.

Т.е. демо летит в дату прежде назначенную для CRS1.

ЦитироватьCOTS Demonstration Mission - Schedule Update (as of July 10, 2013)
July 2013

Orbital's Antares launch vehicle and Cygnus cargo logistics spacecraft engineering and operations teams are busy preparing for the upcoming Demonstration Mission to the International Space Station (ISS). This mission is the final milestone in the Commercial Orbital Transportation Services (COTS) joint development effort with NASA. The Demonstration Mission will verify the overall capabilities of the cargo delivery system developed under the COTS effort. A successful demonstration will enable Orbital to carry out the first of eight regularly scheduled, fully operational cargo resupply missions under the Commercial Resupply Services (CRS) program before the end of the year. Orbital's teams are now working on a schedule that would enable the company to support a launch in late August. However, the Wallops Flight Facility (WFF) range has also been tasked with supporting another high-profile NASA mission, necessitating NASA to shift the COTS Demonstration Mission schedule to mid-September.

Currently, priority on the WFF range has been given to NASA's Lunar Atmosphere and Dust Experiment Explorer (LADEE) mission, which is being launched aboard a Minotaur V rocket (which is designed, built and operated by Orbital). The LADEE mission has a launch window of September 6-10, with the target launch date being the 6th. Following the launch of the Minotaur V from Pad 0B at Wallops, Orbital is scheduled to conduct the launch of the COTS Demonstration Mission from Pad 0A during a window of September 14-19, with the target date being the 14th. Should preparations and processing for the LADEE mission encounter an unexpected delay, Orbital will continue to integrate the Antares rocket and Cygnus spacecraft to be in a position to conduct the COTS Demonstration Mission as early as the end of August, giving NASA additional options to maximize the launch manifest from Wallops.

Orbital's teams are well along in preparations for the COTS Demonstration Mission. The two stages of the Antares rocket have been mated and the launch vehicle is in final integration and testing. Likewise, the Cygnus spacecraft is already fueled and loaded with about 1,300 lbs. of cargo (with an additional 250 lbs. of late load cargo expected). Soon, integration of the Cygnus spacecraft with the Antares rocket will begin, leading to launch readiness in late August. The Cygnus spacecraft is currently scheduled to berth with the ISS on September 22.
