Улучшенную модификацию ракеты Antares запустят в I квартале 2016 г
Цитата
ВАШИНГТОН, 10 дек — РИА Новости. Частный подрядчик НАСА компания Orbital намерена осуществить запуск улучшенной модификации ракеты Antares в первом квартале 2016 года, говорится в заявлении компании.

Ракета-носитель Antares с космическим грузовиком Cygnus, который должен был доставить более двух тонн груза на МКС, взорвалась в конце октября в момент старта на космодроме Валлопс (штат Виргиния). Причины катастрофы официально объявлены пока не были, однако эксперты указывают на то, что авария могла быть вызвана проблемами в двигателе. Antares комплектуется двигателями AJ-26, сделанными на основе советских НК-33, законсервированных еще со времен незавершенной лунной пилотируемой программы.

"Компания подтвердила свою способность ускорить внедрение новой основной двигательной системы для ракеты Антарес и планирует три дополнительных запуска (в рамках миссии по доставке грузов на МКС) в первом, втором и четвертом квартале 2016 года с использованием улучшенного аппарата", — говорится в заявлении Orbital.
Сборка и тестирование обновленной ракеты может начаться уже в середине 2015 года. Компания пока не приводит деталей о том, какая модель двигателей предусмотрена для улучшенной модификации ракеты Antares. Ранее руководство Orbital заявляло, что может отказаться от использования ракетных двигателей AJ-26 до того момента, пока не будет доказана их безопасность. Оснащенный новым двигателем Antares позволит выводить на орбиту более тяжелые аппараты, в связи с чем каждый рейс грузовика Cygnus будет доставлять на МКС на 20% больше грузов, отмечают в компании.

До того времени, как Orbital сможет использовать собственную улучшенную ракету, запуск грузовика Cygnus будет осуществляться при помощи ракеты Atlas V, разработанной United Launch Alliance. "Orbital заключила контракт с ULA на запуск Cygnus ракетой-носителем Atlas V с космодрома на мысе Канаверал в четвертом квартале 2015 года и возможностью при необходимости второго запуска в 2016 году", — свидетельствует заявление.

Использование более мощной ракеты позволит увеличить грузоподъемность Cygnus на 35%, что в конечном итоге "позволит Orbital завершить остающиеся (по контракту) доставки грузов на МКС за четыре запуска вместо запланированных ранее пяти". В компании подчеркивают, что изменения не повлекут за собой дополнительных финансовых трат для НАСА и позволят до конца 2016 года выполнить все предусмотренные 1,9 миллиардным контрактом обязательства компании-разработчика перед агентством.

Orbital Announces Additional Details Concerning CRS Program and Antares Launcher Go-Forward Plans
-- Next Cygnus Cargo Spacecraft to Be Launched on Atlas V Vehicle in Fall 2015 --
-- Upgraded Antares Rockets to Resume Flights from Wallops Island in Early 2016 --
(Dulles, VA 9 December 2014) ....
The company’s go-forward plans for the CRS program and Antares launch vehicle include these major elements:
•    Atlas V Launch: Orbital has contracted with United Launch Alliance for an Atlas V launch of a Cygnus cargo spacecraft from Cape Canaveral, Florida, in the fourth quarter of 2015, with an option for a second Atlas V launch in 2016 if needed. The Atlas rocket’s greater lift capacity will allow Cygnus to carry nearly 35% more cargo to the ISS than previously planned for CRS missions in 2015.
•    Antares Propulsion Upgrade: The company has confirmed its ability to accelerate the introduction of a new main propulsion system for the Antares rocket and has scheduled three additional CRS launches in the first, second and fourth quarters of 2016 using the upgraded vehicle. The greater payload performance of the upgraded Antares will permit Cygnus spacecraft on each of these missions to deliver over 20% more cargo than in prior plans. With necessary supplier contracts now in place, the first new propulsion systems are expected to arrive at the Antares final assembly facility at Wallops Island, Virginia in mid-2015 to begin vehicle integration and testing.
•    Wallops Launch Site Repairs: The Mid-Atlantic Regional Spaceport (MARS) has assessed the clean-up, repair and reconstruction work necessary to return the Wallops launch complex to operational status. Current plans call for repairs to be substantially completed by the fall of 2015, with recertification taking place before year end.  
The flexibility of Orbital’s Cygnus cargo spacecraft to accommodate heavier cargo loads, together with the greater lift capacity of the Atlas V and upgraded Antares vehicles, will allow the company to complete all currently contracted ISS deliveries in four missions instead of the five previously planned flights over the next two years. In addition, the company’s revised approach is not expected to create any material adverse financial impacts in 2015 or future years as Orbital carries out the CRS cargo delivery and Antares propulsion upgrade programs.

Orbital Announces Additional Details Concerning CRS Program and Antares Launcher Go-Forward Plans

-- Next Cygnus Cargo Spacecraft to Be Launched on Atlas V Vehicle in Fall 2015 --

-- Upgraded Antares Rockets to Resume Flights from Wallops Island in Early 2016 --

(Dulles, VA 9 December 2014) – Orbital Sciences Corporation (NYSE: ORB), one of the world’s leading space technology companies, today announced new details in its plans to resume cargo flights to the International Space Station (ISS) and to accelerate the introduction of an upgraded Antares launch vehicle. In formulating its go-forward plans, the company’s primary objective is to fulfill its commitment to NASA for ISS cargo deliveries with high levels of safety and reliability and minimum disruption to schedules. As previously announced, these plans are expected to allow Orbital to accomplish all remaining cargo deliveries under its current Commercial Resupply Services (CRS) contract with NASA by the end of 2016 and with no cost increase to the space agency.

The company’s go-forward plans for the CRS program and Antares launch vehicle include these major elements:

• Atlas V Launch: Orbital has contracted with United Launch Alliance for an Atlas V launch of a Cygnus cargo spacecraft from Cape Canaveral, Florida, in the fourth quarter of 2015, with an option for a second Atlas V launch in 2016 if needed.

America’s spaceflight industry would like to wean itself off Russian rocket engines. That’s easier said than done.
With political tensions between the United States and Russia running high, both the U.S. government and the American spaceflight industry want to reduce their reliance on the Russian rocket engines that power a number of American private and military space launch vehicles. But even as Congress considers banning Russian launch technology fr om U.S. military satellite launches, Orbital Sciences’ search for a new rocket engine following a spectacular late-October rocket explosion demonstrates just how difficult it’s been for American space launch companies to wean themselves off of Russian rocket hardware—or to field new, American-made replacements.
If you’re not familiar with Orbital Sciences http://fortune.com/company/orb/ORB -2.65% , it’s the less-flashy competitor to Elon Musk’s SpaceX. Orbital has long track record in the spaceflight industry, and alongside SpaceX its Antares rockets and Cygnus spacecraft serve as NASA’s only homegrown means of resupplying the International Space Station. Orbital was attempting to make one of its NASA-contracted runs to the ISS on October 28 when one of the refurbished Soviet-era AJ26 engines malfunctioned just seconds after liftoff, bringing the rocket and cargo down in a magnificent fireball.
With pressure already mounting to move away from Russian rocket hardware, Orbital announced a week later that it would stop using the AJ26 engine. But just how it will replace it and get back to launching is anybody’s guess. Orbital would like to end its reliance on Russian rocket engines. But with contract obligations to NASA and no obvious replacement option on the market, the company may not have any choice.

“These are complicated, absolutely cutting edge pieces of equipment,” says Jonathan Beland, a senior analysts at Avascent Group, D.C.-based consultancy serving the aerospace and defense industries. “You can’t just go down to the corner store and pick one up, the timeline for development is several years.”

That’s a problem for a domestic rocket engine industry that is dominated by two non-competitive companies: Aerojet Rocketdyne, which produces liquid-fueled rocket engines, and Alliant Techsystems http://fortune.com/company/atk/ATK -1.93% , whose expertise lies in solid-fuel rockets. Both companies, especially the former, serve government clients that tend to push up the price of hardware beyond what the private space industry wants to pay.
Likewise for United Launch Alliance, a collaboration between Boeing http://fortune.com/company/ba/BA -3.87% and Lockheed Martin http://fortune.com/company/lmt/LMT -1.42% that has a virtual monopoly on U.S. national security launches. In an effort to wean itself off of Russian built RD-180 engines, ULA is in the process of developing a new home-grown rocket engine alongside Blue Origin, the commercial spaceflight company started by Amazon CEO Jeff Bezos, but that engine won’t be available until at least 2019.
Orbital’s problem is more acute. To keep its obligations to NASA, Orbital needs a new rocket engine, one that’s built to the proper specifications, readily available, and—perhaps most importantly—affordable. To maintain its schedule the company has indicated it intends to launch its Cygnus spacecraft on another launch vehicle, perhaps atop one of competitor SpaceX’s Falcon 9 rockets, until it can fly on its own again in 2016—ideally with a new, non-Russian engine.
“I don’t see how Orbital, given all the negative publicity around Russian engines, could go with another Russian engine,” says Marco Caceres, space industry analyst for aerospace and defense consultancy Teal Group. “How could the CEO explain another accident to shareholders? I think you have to go with a red, white, and blue company.”
But finding that company could prove daunting. Aerojet Rocketdyne’s existing production line produces powerful engines for the Delta IV and NASA’s new super-heavy-lifting Space Launch System—likely too much engine for Orbital’s medium-sized Antares rocket, Caceres says. Orbital could ask Aerojet Rocketdyne to redesign something more in tune with its needs, but that requires time and money. Or it could try to buy some engines from SpaceX, which makes its own propulsion systems, though it’s certainly not clear SpaceX would have the engines to spare. (Each Falcon 9 flight requires 10 of SpaceX’s Merlin engines.)

Orbital does have a safety valve in this situation. A merger with ATK agreed to earlier this year and blessed by the Department of Justice last week could allow Orbital to take advantage of its new partner’s solid-fuel rocket technology, Caceres says. “If they do that, they’d get a fairly reliable, powerful engine from the company they are merging with,” he says. “It would be cheaper than anything they can buy, they would immediately have a vertically integrated vehicle, which would make them more competitive with their primary competitor, SpaceX. And ATK has them ready to go.”

But it’s not clear if Orbital will go that route, as ATK’s expertise in solid fuel rockets doesn’t necessarily dovetail with Orbital’s Antares rocket, which would ideally employ liquid-fueled propulsion. (Among many key differences between the technologies: liquid-fueled engines allow for adjustable throttling during flight, whereas solid-fuel engines do not.)
If Orbital can’t look to an American rocket manufacturer, and it can’t look to Europe—“There’s nothing the Europeans do that’s remotely affordable,” Caceres says. “It’s a jobs program”—there is a country out there that will happily deal in inexpensive rocket engines. In fact, that country has the right liquid-fueled engines for the job, and it has them now.
That country is Russia.
In fact, in the wake of Orbital’s October launch incident, Russian media reported that Orbital would power future Antares rockets not with the failed AJ26, but with the RD-193 produced by Russian spaceflight tech firm Energomash. But while it’s true that Orbital had opted to buy the RD-193 for future Antares missions before the accident, the company has not said if it will go forward with the deal. Those Russian media reports may have been an attempt to push Orbital to make good on the deal. Given the U.S. market for rocket engines, Orbital may not have much of a choice anyhow.

“It comes down to: What are your options?” says Carissa Christensen, managing partner at Alexandria, Va.-based space and technology research firm Tauri Group. “If you can get a Russian engine cheap, and your other option is to wait years and spend hundreds of millions of dollars, maybe that’s what you do. It’s going to be a hard call.”
The takeaway, especially in light of SpaceX’s success, might be “vertically integrate or die,” though its technology is far from legacy; a mishap with its Falcon 9 rocket or Merlin engine would put America’s private spaceflight industry in a serious bind, underscoring the industry’s lack of options wh ere rocket engines are concerned. Don’t expect another U.S. aerospace giant to jump into the saturated rocket engine market in the near-term—though as the private spaceflight industry continues its upward trend, that could change.
“I don’t see the market growing strongly enough in the next few years to spur new entrants into the market,” Avascent’s Beland says. “But in the long term? I can’t say anything about that. The space industry has bucked too many long-term trends over the decades.”

Российская пресса с насмешкой сообщает о взрыве грузовой ракеты Antares в США. Такая реакция российской прессы не удивительна на фоне того, что Россия грозит США прекратить поставки ракетных двигателей в ответ на санкции, которые Вашингтон ввел против Москвы из-за военной агрессии против Украины.

Как сообщает New Republic, главный рупор пропаганды Кремля в англоязычном мире телеканал Russia Today сообщил, что ракета Antares якобы "украинско-американского производства" и была изготовлена на КБ "Южное", пишут Новости Украины Vesti-ua.net со ссылкой на zn.ua.

"Проанализировав санкции против нашего космодрома, предлагаю США доставлять своих астронавтов на МКС с помощью батута", - сказал с издевкой вице-премьер России и куратор авиакосмической отрасли Дмитрий Рогозин.

Однако, как пишет The Guardian, сарказм и издевательства руссиян преждевременны. Как оказалось, ракета изготовлена в России на предприятии "Кузнецов". Москва продала американской компании Orbital Sciences Corporation двигатели, которые были изготовлены еще во времена СССР для полета на Луну.

На предприятии "Кузнецов" уже взялись отрицать, что авария Antares произошла из-за низкого качества их продукции. Конструкторы обвиняют США, эксперты которых могли модифицировать ракетные двигатели.

"Инцидент может усилить критику NASA за субподрядные соглашения с частными космическими компаниями для доставки грузов на МКС после закрытия программы "Шаттл", - пишет The Guardian.
