Key return to flight milestone looms for Antares rocket

Targeting a resumption of Antares cargo launches to the International Space Station as soon as July, Orbital ATK plans to roll out an upgraded Antares rocket to a launch pad in Virginia this week for a 30-second firing of the booster’s new engines.
Technicians working at the Antares launch site on Virginia’s Eastern Shore are finishing up preparations for a series of tests and dress rehearsals for the rocket’s return-to-flight.
The first Antares launch in nearly two years is set for early July, perhaps as soon as July 6, with a Cygnus supply ship carrying logistics, provisions and experiments to the space station and its six-person crew.
Before the cargo mission, dubbed OA-5 in Orbital ATK’s flight sequence, is cleared for blastoff, engineers have several more major tests in store for the upgraded Antares rocket.
The next step is scheduled as soon as this week with the rollout of an Antares first stage booster to pad 0A at the Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility in Virginia, according to Blake Larson, Orbital ATK’s chief operating officer.
Fitted with two newly-built RD-181 engines fr om Russia, the Antares first stage will roll out of its Horizontal Integration Facility at Wallops for the one-mile trip south to the launch pad, wh ere it be hoisted vertical for several weeks of tests.
One of the first tests will be a wet dress rehearsal, in which the Antares launch team will load kerosene and liquid oxygen propellants into the booster.
“We’ll basically run the pre-launch sequence and go right up to the point of firing the engines. We’ll load all the commodities. We’ll load all the pressurant gases. We’ll apply all the purges. We’ll get everything ready and see everything work properly between the vehicle and the pad systems, and then we’ll stop the test right before engine ignition,” said Kurt Eberly, Orbital ATK’s Antares deputy program manager.

“We’ll detank and look at all that data. If that all looks good, roughly a week or so later, we’ll re-initialize the sequence, load the tanks, and go for the hotfire test.
The 30-second test firing of the twin-engine first stage is scheduled for late May.
The engines will be programmed to ramp up to full power — equivalent to more than 800,000 pounds of combined thrust — and go through a steering check as the control computers throttle the engines to different thrust levels they will see in flight.

“We want to see steady-state operation at each of the operating points in flight,” Eberly said. “Once we hit those points, we have some mixture ratio excursions that we will command, and then we’ll also be vectoring the nozzles during the test with varying frequency content looking to excite any adverse modes and interactions between the components.”
Orbital ATK ordered RD-181 engines from Russia’s NPO Energomash, the builder of the Atlas 5 rocket’s RD-180 engine, in the wake of a catastrophic launch failure moments after a liftoff from Virginia in October 2014. The Antares rocket crashed near the Antares launch pad, toppling two of the facility’s lightning protection towers and carving a huge crater just northeast of pad 0A’s elevated launch mount.
A commercial Cygnus cargo freighter en route to the International Space Station with supplies was destroyed in the failure.
Investigators from Orbital ATK and NASA concluded the fiery mishap started about 15 seconds after liftoff inside a liquid oxygen turbopump on one of the rocket’s first stage AJ26 engines.
The engines were built more than 40 years ago by the Soviet Union’s Kuznetsov Design Bureau for the N1 moon rocket. When the Soviet moon program was canceled, officials put the engines — called NK-33s in Russia — in long-term storage before Aerojet Rocketdyne imported the powerplants to the United States in the 1990s.
Aerojet Rocketdyne modified the engines for use on U.S. launchers, qualifying the NK-33s for U.S. propellants and adding mechanisms for in-flight steering. The company renamed the upgraded engines as AJ26s.
Orbital ATK intended to move away from the AJ26 engine before the 2014 launch failure, but the accident accelerated the company’s plans. Officials announced two months after the rocket crash that NPO Energomash would provide newly-built RD-181 engines for future Antares launches.
Since the first two RD-181 engines arrived from Russia last year, ground crews at Wallops have mated the powerplants to the Antares rocket’s Ukrainian-made first stage structure. The booster and RD-181 engines set for the hotfire test later this month are assigned to fly on the OA-7 launch scheduled at the end of 2016.
The RD-181 engine generates 13 percent more thrust than the AJ26 and burns its mix of kerosene and liquid oxygen propellants more efficiently, Eberly said in an interview with Spaceflight Now.

“The combination of those two (improvements) give us a good 20 to 25 percent performance improvement to the orbit that we’re flying to in low Earth orbit to inject the Cygnus for these cargo runs,” Eberly said.
The single-chamber RD-181 is similar to the dual-nozzle RD-180 engine flown on United Launch Alliance’s Atlas 5, producing about the thrust of its larger cousin. NPO Energomash produces a nearly identical engine named the RD-191 for Russia’s Angara rocket family.
The new version of the rocket is known as the Antares 230 configuration, according to Orbital ATK.
Eberly said the new engines required a new type of thrust adapter, a structural component that mechanically connects the RD-181s to the first stage. Orbital ATK also built avionics systems for the engines, developing the new controllers in-house to replace the AJ26 controller sourced from an external supplier, Eberly said.
“It’s about the same physical size as the AJ26,” Eberly said. “It uses the same propellants. The combustion cycle (is the same), which means that the mixture ratio between the two propellants — between the kerosene and the liquid oxygen — is very close.”
Each engine is individually steered to guide the Antares rocket in flight, and designers positioned the RD-181 engine nozzles in the same place as the AJ26 engine cones, minimizing changes to the launch pad and ground support equipment.
“The new components were the engines, obviously, the new thrust adapter, and then feedlines, which are the pipes that connect the core tanks to the engines, and then some new avionics and software to control it all,” Eberly said. “That was really what changed. Everything forward of the first stage is identical.”
Orbital ATK builds the solid-fueled Castor 30XL second stage for the Antares rocket. It is unchanged from the upper stage on previous Antares models.
The higher-performing RD-181 engines will alter the Antares rocket’s launch profile, Eberly said. Because the new engines will consume fuel from the same first stage tanks first designed for the AJ26, they will drain the propellant supply faster.
“Whereas with the AJ26, we were on the order of 235 seconds of first stage burn, we’ll be down around 214 seconds for these RD-181s,” Eberly said. “They will just consume the propellants that much faster.”

The Italian-built cargo module for the next Cygnus mission arrived at the Wallops launch site earlier this year. The service module, containing power and propulsion for the supply ship, will be transported from Orbital ATK’s headquarters and factory in Dulles, Virginia, to Wallops in mid-May, officials said.

Немного старое...
Dulles, VA 31 May 2016 – Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, today announced it conducted a full-power "hot fire" test of the upgraded first stage propulsion system of its Antares medium-class rocket using new RD-181 main engines. The 30-second test took place at 5:30 p.m. (EDT) on May 31, 2016 at Virginia Space’s Mid-Atlantic Regional Spaceport (MARS) Pad 0A. Initial indications are that the test was fully successful. The Antares engineering team will review test data over the next several days to confirm that all test parameters were met. Assuming the success of the test is confirmed, it will clear the way for the resumption of Orbital ATK’s cargo logistics missions to the International Space Station (ISS) fr om Wallops Island, Virginia, currently scheduled for July.

“Early indications show the upgraded propulsion system, core stage and launch complex all worked together as planned,” said Mike Pinkston, Orbital ATK General Manager and Vice President, Antares Program. “Congratulations to the combined NASA, Orbital ATK and Virginia Space team on what appears to be a successful test.”

The primary goal of the test was to verify the functionality of the integrated first stage, including new engines, modified Stage 1 core, avionics, thrust vector control and pad fueling systems in an operational environment.

During the test, a number of operational milestones were met including full propellant loading sequence, launch countdown and engine ignition and shut down commands, as well as multiple throttle settings including full engine power. The test also validated the launch pad’s operation, including propellant tanking and the use of the water deluge system to protect the pad from damage and for noise suppression.

Orbital ATK will now purge and clean the engines of residual propellants and return the first stage used in this test to the Horizontal Integration Facility for full reconditioning prior to its use on the OA-7 mission slated for later this year. The Orbital ATK team will continue to prepare the Antares rocket that will launch the OA-5 mission, which is in the final stages of integration, systems testing and check-out in preparation for launch this summer.

Each of the new flight RD-181 engines has undergone hot fire acceptance testing at the manufacturer’s facility prior to being shipped to Orbital ATK. A certification test series was successfully completed in the spring of 2015 wh ere a single engine was test fired seven times, accumulating 1,650 seconds of test time and replicating the Antares flight profile, before being disassembled for inspection.

“The successful stage test, along with the extensive testing of each new RD-181, gives us further confidence in the first stage propulsion and in moving forward to launch,” said Pinkston. “We are now focused on the OA-5 mission and launching the enhanced Cygnus spacecraft to the International Space Station on our upgraded, higher-performing Antares rocket.”

The enhanced Cygnus recently flew on the successful OA-4 and OA-6 missions, launched in December and March, respectively. The spacecraft has several new features, including larger cargo capacity, the use of Orbital ATK’s lightweight UltraFlexTM solar arrays, a mass optimized service module structure and a lighter weight propulsion system. Cygnus, like most Orbital ATK spacecraft, is compatible with multiple launch vehicles, enabling the recent use of United Launch Alliance’s Atlas V launch vehicle. The OA-5 mission will be the first Antares mission to launch the enhanced Cygnus.

Orbital ATK has successfully completed five cargo delivery missions to the ISS, including a demonstration mission in 2013 and four operational missions under the CRS-1 contract from 2014 to present. In total, the company has delivered 24,000 pounds (10,900 kilograms) of essential equipment and supplies in support of ISS crew and operations.

Under the CRS contract with NASA, Orbital ATK will deliver approximately 62,000 pounds (28,000 kilograms) of cargo to the ISS over 11 missions through 2018. The partnership is changing the way NASA does business, helping build a strong American commercial space industry and freeing the agency to focus on developing the next-generation rocket and spacecraft that will enable humans to travel farther in space than ever before. Orbital ATK is also on contract for six initial missions for the follow-on CRS-2 program.

About the Mission

For the OA-5 mission, Orbital ATK’s Cygnus advanced maneuvering spacecraft will carry approximately 2,400 kg (5,290 lbs.) of supplies and science experiments for the International Space Station (ISS). Under the Commercial Resupply Services (CRS) contract with NASA, Orbital will deliver approximately 28,700 kilograms of cargo to the ISS. OA-5 is the sixth of these missions.

Cygnus will be launched into orbit using Orbital ATK’s upgraded Antares 230 launch vehicle fr om Virginia Space’s Mid-Atlantic Regional Spaceport Pad 0A on Wallops Island, Virginia at NASA’s Wallops Flight Facility. The Antares 230 vehicle features all new RD-181 engines which provide increased performance and flexibility to the Orbital ATK cargo delivery service.

After being launched into low-Earth orbit, the Cygnus spacecraft will use its substantial maneuvering capability to transport the cargo from a low parking orbit to the ISS wh ere it will be grappled by the ISS crew using the station’s robotic arm and berthed to the station. After the cargo is removed and any ISS disposal items are added, Cygnus will depart from the ISS, and begin secondary payload missions.

For the OA-5 mission Cygnus will carry the Saffire II payload experiment to studycombustion behavior in microgravity. Data from this experiment will be downloaded via telemetry. In addition, a NanoRack deployer will release Spire Cubesats used for weather forecasting. These secondary payload operations will be conducted after Cygnus departs the ISS.

Orbital ATK: корабль Cygnus сможет отправиться к МКС после 10 июля
9 июня 2015

В настоящее время корабль и его ракета-носитель Antares находятся на космодроме на острове Уоллопс у побережья штата Вирджиния

ВАШИНГТОН, 9 июня. /Корр. ТАСС Иван Лебедев/. Американский грузовой корабль Cygnus через месяц будет полностью готов отправиться в полет к Международной космической станции (МКС) по заказу NASA. Как сообщил в среду журналистам официальный представитель компании Orbital ATK Брайан Бенески, его старт может состояться после 10 июля.

"Приготовления идут очень хорошо", - отметил специалист. Ожидается, что точную дату пуска космическое ведомство США назовет в ближайшие недели. В настоящее время корабль, а также его ракета-носитель Antares находятся на космодроме на острове Уоллопс, расположенном в Атлантическом океане у побережья штата Вирджиния.

Cygnus доставит экипажу орбитального комплекса более 2,5 тонн полезных грузов, включая воду, продовольствие и материалы для научных экспериментов. Кроме того, он привезет на станцию оборудование для вывода в космическое пространство миниатюрных спутников, предназначенных для наблюдения за погодой на Земле.

Бенески также рассказал, что по традиции, установленной в Orbital ATK, новый корабль будет назван в честь одного из американских астронавтов. На этот раз на его борту будет начертано имя Алана Пойндекстера, который принимал участие в осуществлении программы МКС и умер в 2012 году. Ранее один из таких кораблей был назван в честь участника знаменитого советско-американского проекта "Союз-Аполлон" Дональда Слейтона.

В ходе предстоящего пуска на модернизированной ракете Antares впервые будут использованы российские двигатели РД-181 производства НПО "Энергомаш". Это будет ее первый старт после катастрофы, случившейся в октябре 2014 года, когда она взорвалась вместе с кораблем прямо на космодроме на острове Уоллопс.

Пока продолжались доработка и испытания Antares с новой реактивной установкой, Orbital ATK использовала для отправки своего "грузовика" носитель Atlas V консорциума United Launch Alliance, созданного гигантами авиакосмической промышленности США - компаниями Boeing и Lockheed Martin. Контракт Orbital ATK с NASA на общую сумму $1,9 млрд, подписанный три года назад, предусматривает еще три рейса Cygnus к МКС.

Полет корабля Cygnus к МКС перенесен с июля на август
17 июня, 21:19 UTC+3
По мнению экспертов, перенос может быть связан с расписанием пусков других кораблей к МКС

ВАШИНГТОН, 17 июня. /Корр. ТАСС Иван Лебедев/. Полет американского грузового корабля Cygnus к Международной космической станции (МКС) перенесен с июля на август. Об этом говорится в заявлении официального представителя компании Orbital ATK Шон Уилсон, опубликованном в пятницу на сайте специализированного еженедельника Space News.
По ее словам, корабль будет запущен с помощью ракеты Antares к орбитальному комплексу "в течение августа". Ранее ожидалось, что это произойдет примерно в середине июля. Причины переноса старта представитель компании, построившей Cygnus по заказу NASA, не назвала. Эксперты предположили, что это может быть связано с расписанием пусков других кораблей к МКС, однако портал космической информации NASASpaceFlight.com сообщил, что во время недавних испытаний первой ступени Antares наблюдалась "небольшая вибрация".
При этом Уилсон отметила, что проверка прошла успешно и специалисты Orbital ATK "анализируют полученные данные". В ходе испытания, состоявшегося в начале июня, на 30 секунд был включен новый двигатель РД-181 производства российского НПО "Энергомаш", который теперь устанавливается на американском носителе. Менеджер проекта Майк Пинкстон заявил, что, "согласно предварительным данным, реактивная система, главная ступень и стартовый комплекс работали вместе, как и было запланировано".
В настоящее время Cygnus и Antares находятся на космодроме на острове Уоллопс, расположенном в Атлантическом океане у побережья штата Вирджиния. Корабль доставит экипажу МКС более 2,5 тонны полезных грузов, включая воду, продовольствие и материалы для научных экспериментов. Кроме того, он привезет на станцию оборудование для вывода в космическое пространство миниатюрных спутников, предназначенных для наблюдения за погодой на Земле.
