У Антареса довольно "растянутая" первая ступень, поэттому она может улететь далеко. А поскольку разделение происходит на большой высоте с малыми скоростными напорами, имеет смысл скинуть вскоре и ГО.

Первый запуск ракеты "Антарес" можно будет увидеть из столицы США
13:41 17.04.2013
Как отмечает Orbital, ракета поднимется достаточно высоко над горизонтом, что ее можно будет увидеть со ступеней Капитолия. Высшей точки на небе с точки зрения жителей Вашингтона она достигнет на 230-й секунде после старта.


МОСКВА, 17 апр — РИА Новости. Первый испытательный запуск ракеты "Антарес" с масс-габаритным макетом частного космического грузовика Cygnus ("Лебедь"  можно будет наблюдать прямо из столицы США Вашингтона, сообщает разработчик ракеты и корабля, компания Orbital Sciences.
Запуск ракеты планируется на 17.00 по времени восточного побережья США 17 апреля (01.00 мск 18 апреля) с площадки Среднеатлантического регионального космопорта (MARS) на острове Уоллопс, штат Виргиния. На данный момент погода благоприятствует пуску, ранее метеорологи заявляли, что существует вероятность в 55% неподходящих для запуска условий. Если старт будет отложен, "Антарес" сможет стартовать 18-21 апреля.
Как отмечает Orbital, ракета поднимется достаточно высоко над горизонтом, что ее можно будет увидеть со ступеней Капитолия. Высшей точки на небе с точки зрения жителей Вашингтона она достигнет на 230-й секунде после старта.

Огневые испытания ракеты "Антарес"

 Ракета "Антарес", которая ранее успешно прошла огневые испытания, должна будет вывести на орбиту высотой 250-300 километров демонстрационный масс-габаритный макет корабля Cygnus, оснащенный датчиками для контроля параметров полета. В случае успешного запуска Orbital продолжит подготовку к первому запуску корабля Cygnus, который, как ранее сообщало НАСА, предварительно запланирован на начало лета.
Ракета Antares создавалась при участии украинского предприятия "Южмаш" с использованием разработок, опробованных на ракете "Зенит". Она будет выводить в космос космический грузовик Cygnus грузоподъемностью от 2 до 2,7 тонны. 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 к Международной космической станции. http://ria.ru/science/20130417/933099617.html

 Я бы сказал, что разделение происходит уже в космосе. ГО сбрасывается также до включения двигателя второй ступени. Поэтому и первая ступень и части ГО летят практически по одной траектории, и все это падает с высоты более 189 км.
Согласно
http://www.orbital.com/Antares-Cygnus/files/AONE-Mission-Overview.pdf
Выключение двигателей 1-й ступени на 230 секунде, на высоте 107 км;
отделение 1-й ступени на 235 секунде, на высоте 113 км;
отделение ГО на 319 секунде, на высоте 184 км;
включение двигателя 2-й ступени на 328 секунде, на высоте 189 км.
С 230 по 328 секунду - пассивный участок, на котором первая ступень получает только небольшой импульс увода либо от толкателей, либо от РДТТ разделения ступеней (не знаю, что применяется на Антаресе).
Поэтому и район падения для всех частей один.

Интересный эффект: Для наблюдателя из Вашингтона будет казаться, что после выключения двигателей 1-й ступени ракета падает, хотя она на самом деле до включения второй ступени наберет еще более 80 км высоты.

WEDNESDAY, APRIL 17, 2013

1300 GMT (9 a.m. EDT)
 The launch countdown is underway at NASA's Wallops Flight Facility, with clocks set to a scheduled liftoff time of 5 p.m. EDT (2100 GMT) for the first test launch of the Orbital Sciences Antares rocket.

The eight-hour countdown is beginning now with a call-to-stations for the Antares launch team. Over the next few hours, engineers will power up the 13-story rocket, load the launcher with refined RP-1 kerosene and liquid oxygen propellants, and activate the booster's systems for testing to ensure all is ready for flight.

The launch window has been shortened to two hours and now closes at 7 p.m. EDT (2300 GMT). The abbreviated launch window was planned going into the countdown and was conceived to ensure the launch team is not overworked and on console for too long, according to Orbital Sciences.

Once engineers begin loading super-cold liquid oxygen into the rocket's first stage, the available launch window will be condensed to 15 minutes. Orbital says the reason is to make sure the cryogenic oxidizer does not boil off too much during the countdown, a concern due to the limited supply of liquid oxygen available at the launch pad to replenish the rocket's tanks.

Orbital Sciences says technicians completed closeouts of final arming of the Antares rocket last night at about 9 p.m. EDT.

The weather continues to look iffy for today's launch, with less than a 50 percent chance of acceptable conditions during the launch window.

Antares rocket engines lean on Russian moon legacy
BY STEPHEN CLARK
SPACEFLIGHT NOW
Posted: April 16, 2013

More than four decades ago, working under the orders of the Soviet leadership, technicians toiled in anonymity to build dozens of rocket engines to power Russian moon shots off planet Earth, intending to flaunt the supremacy of communism over capitalism.

On Wednesday, those same engines - designed and constructed under the umbrella of totalitarianism in the former Soviet Uni on - will launch a commercial rocket conceived for a money-making mission.

The privately-developed Antares rocket, operated by Orbital Sciences Corp., will take off for the first time Wednesday in a launch window opening at 5 p.m. EDT (2100 GMT). The Antares launch base is at NASA's Wallops Flight Facility on the Virginia coast.

The Antares first stage is powered by two of the Russian-built engines - named the AJ26 engine by Aerojet, the powerplant's main U.S. contractor.

In Russia, the units are called NK-33 engines. The original manufacturer was Kuznetsov, a Russian design bureau which built engines for space launchers and Russia's strategic military bombers.

After the engines were built, Soviet space dreams were adjusted to focus on Earth-orbiting space stations, leaving the engineering marvels in storage without a purpose.

Aerojet imported the engines to the United States in the 1990s in an effort to develop a commercial rocket to launch U.S. military satellites. The California-based propulsion company competed to supply engines for the Atlas 5 rocket, which was then under development by Lockheed Martin Corp.

Lockheed Martin sel ected another Russian engine to power the Atlas 5's first stage, leaving Aerojet with a stock of three dozen NK-33 engines at the company's headquarters in Sacramento, Calif.

Aerojet modified the NK-33 engines by adding a gimbal mechanism for steering, installing modern instrumentation, and qualifying the engines for U.S. propellants, according to Julie Van Kleeck, vice president of space programs for Aerojet.

Following Lockheed Martin's decision to use another engine, the NK-33 engines appeared to be left in the dust for a second time until Orbital Sciences came along with a proposal for the Antares rocket - then called the Taurus 2 - in 2007.

Once Orbital's Antares rocket was sel ected by NASA to supply the International Space Station, the company purchased 20 of the engines fr om Aerojet to power 10 launches - two test flights and eight operational missions, according to Kurt Eberly, deputy Antares project director at Orbital Sciences.

"If you want to get an engine like this, you can't find it in the United States," Eberly said. "I think it speaks to the state of the liquid propulsion industry in the United States."

The engine is noteworthy for its efficiency. It produces more power for its weight than any other liquid-fueled engine ever built.

Officials from Kuznetsov, the original manufacturer of the engines, traveled to Virginia to witness the Antares launch.

"I think they are excited to finally see their engine launch something into orbit," Eberly said.

According to Eberly, purchasing the engines from Russia was the most cost-effective solution for the Antares rocket's first stage. A comparable engine developed from scratch could cost more than $500 million, not including the price per unit, he said.

There are more NK-33 engines stored in Samara, Russia, but there is growing demand for the engines. Russia is working on a light version of the Soyuz rocket which will use one NK-33 engine on the first stage.

The Soyuz 2-1v rocket could launch for the first time later this year, and the new Russian launcher will compete with Orbital Sciences and Aerojet for access to the lim ited stockpile.

Russia could restart production of the NK-33 engine, but it would take several years to ramp up construction to produce new engines. If Orbital Sciences is successful in finding a secondary market for the Antares rocket, such as launching commercial, military or scientific satellites, the company may need to find an alternate engine in the long run, Eberly said.

Aerojet is working with NASA and the U.S. Air Force to design a kerosene-fueled U.S.-built alternative to the Atlas 5 rocket's RD-180 main engine and to power next-generation boosters for NASA's Space Launch System heavy-lift rocket. Such an engine could be used by Antares in the future, Eberly said.

The NK-33 engine is derived from the NK-15 engine used on the Soviet Union's N1 rocket, a massive launcher designed to hurl manned lunar landers toward the moon. It was Russia's answer to NASA's Saturn 5 moon rocket.

The N1 rocket launched four times on unmanned test flights fr om 1969 to 1972, but all the missions failed to reach orbit. Investigators found no fault with the engines, instead blaming the mishaps on the complexity of the gargantuan rocket, which used 30 engines on the first stage alone.

"They also have thousands and thousands of seconds of test time behind them in a wide variety of conditions and power levels, so we know the engines are robust," said Frank Culbertson, executive vice president and general manager of the Orbital Sciences advanced programs group. "As we went through testing, we did discover there were some effects of aging since they had been in storage for a while, including some stress corrosion cracking. That's what we're correcting with the weld repairs and other inspections."

Engineers added extra inspections after a crack in a fuel line triggered a fire in 2011 during a burn on a test stand at NASA's Stennis Space Center in Mississippi.

"What they bring is an engine that uses a lot of power, has a great deal of performance, and satisfies our needs for getting payloads to orbit," Culbertson said. "We also have a legacy of proven design we can lean on."

WALLOPS ISLAND, Va. — Orbital Sciences Corp. has been cleared to launch the Antares rocket April 17 on its inaugural flight.

Weather permitting — and forecasts show a chance of showers here around launch time — liftoff is scheduled for 5 p.m. EDT.

Orbital aborted a countdown rehearsal April 13 because of a faulty valve in one of the two Aerojet-supplied AJ-26 liquid kerosene engines that power the Antares' first stage. The valve was replaced April 14.

NASA Wallops Flight Facility Site Director Bill Wrobel on April 16 gave the test launch the formal go-ahead. The so-called Authority to Proceed followed a launch readiness review "at which Orbital managers gave a 'go' to proceed to toward launch," NASA said in a statement.
