ЦитатаDespite these outstanding issues, Suffredini presented a timeline chart showing the next SpaceX mission to ISS scheduled for March 2013.   That chart also listed the first flight of Orbital Science's Cygnus cargo spacecraft to the ISS for April 2013, but Suffredini advised the committee not to bank on it because he expects that date to slip.
As the briefing continued it became clear that a delay might be needed in any case because of an unresolved problem that arose when Japan's HTV cargo spacecraft was released from the ISS.   The HTV automatically aborted the release when it detected an "off-nominal trajectory" resulting from friction between the grapple fixture and Canadarm2 that caused Canadarm2 to pull HTV as it was trying to back away.  Suffredini said they are still investigating what happened.  SpaceX uses a different configuration, so it is not issue for the next Dragon flight, he said, but Cygnus uses the same configuration as HTV and "we need to sort it out before Cygnus flies."

ЦитатаCygnus' first visit to the ISS:

While SpaceX are preparing to make their third flight to the ISS, Orbital Sciences Corporation are also hard at work preparing for the debut mission of their Antares rocket and Cygnus spacecraft to the ISS.

With the first milestone in the Antares and Cygnus test program now complete - a 30 second hold-down test of the Antares first stage - which appears at first glance to have been a complete success, the next milestone will be a full-up test flight of the Antares rocket with a dummy Cygnus spacecraft. According to Orbital officials, this milestone is scheduled to be performed around 5 weeks after the hold-down test, which would give a tentative date of early April for the Antares test flight.

The COTS demo flight - where the first Cygnus spacecraft would attempt to rendezvous and berth with the ISS - would be performed around 3 months after the Antares test flight, giving a tentative date of early July for the COTS demo flight.

Finally, the first Antares/Cygnus CRS flight would occur 3-4 months after the COTS demo flight, giving a tentative timeframe of early October-early November for the first Orbital CRS flight - although November has issues from a flight scheduling standpoint, due to a Beta angle cut-out from Nov 2 to Nov 9, and then a period wh ere only one US crewmember will be present on the ISS (thus creating issues for Visiting Vehicle captures) from Nov 10 to Nov 25.

The above schedule however is extremely tentative, and is dependent upon the test flight program proceeding without any issues or setbacks.

Первая ступень будет оставаться на столе в течении недели (1-й недели марта), затем будет перемещена в МИК, восстановлена (после ОИ) и использована для полета по программме CRS. Неделей позже, полностью собранный Антарес с ГВМ Сигнуса будет установлен на стартовом столе. Сама ракета уже практически готова. Далее две недели проверок и испытаний на столе, потом проверочная заправка и слив топлива.
Повреждения стартовых конструкций (после ОИ) незначительны. До пуска планируется установка дополнительного гелиевого холодильника.
Демонстрационный пуск предварительно запланирован на начало апреля. В случае успеха полет Сигнуса по программе COTS состоится летом, а первый полет по программе CRS в конце этого - начале следующего года. Один двигатель (для CRS) уже прошел приемочные испытания в центре Стенниса, приемка второго состоится в течении месяца. С учетом этого на космодроме будет готовое "железо" для четырех ракет.
За каждый пуск Орбитал выплачивает штату Вирджиния (владельцу космодрома) $1.5 миллиона.

ЦитатаWASHINGTON -- Following a successful test firing of its main engine Feb. 25, the Antares rocket developed by Orbital Sciences Corp. is in final integration at its Virginia launch site and scheduled to roll out to the pad in mid-March in preparation for an early April debut, a company official said Feb. 28.
 Скрытый текст:
Antares, developed with financial assistance fr om NASA, will be used to launch Orbital's Cygnus cargo to the international space station (ISS) under an eight-flight, $1.9 billion services contract awarded by the space agency in 2008.
Before Dulles, Va.-based Orbital can begin routine deliveries, however, it must carry out two successful Antares demonstrations, the second of which will carry a station-bound Cygnus capsule. The first will attempt to place a simulated Cygnus capsule into the initial orbit used for space station deliveries.
The Antares team at NASA's Wallops Flight Facility in Wallops Island, Va., and the Virginia Commercial Space Flight Authority that operates the launch pad will spend the next five to six weeks refurbishing the platform and parsing a mountain of data from the 29-second hot fire of the rocket's core stage.
According to the data examined so far, Antares passed "with flying colors," Mike Pinkston, Orbital's program manager for Antares, said Feb. 28.

Pinkston said the just-fired core stage will remain on the pad through the first week of March, and then be brought back to Orbital's nearby Horizontal Integration Facility, wh ere it will be refurbished for a future station resupply mission. A week later, a fully integrated Antares, carrying a Cygnus mass simulator, will be brought to the pad.
"The test-mission rocket itself is really all but done," Pinkston said. "It's actually tracking to a schedule that's ahead of the activities we've got going on at the pad, so the rocket itself won't be our critical path."
Once raised at the pad, Antares will undergo a roughly two-week series of checks to verify the fully integrated rocket along with its interfaces with the pad and launch range, Pinkston said. "Then we will go through a wet-dress rehearsal, which will fuel and then defuel the rocket."
Pinkston would not say what day Orbital has targeted for launch.

Antares will launch from Pad-0A at the Mid-Atlantic Regional Spaceport, which is operated by the state of Virginia. The Virginia Commercial Space Flight Authority leases Pad-0A to Orbital, which last year signed a deal with the state for 10 Antares launches. The state is charging Orbital $1.5 million per launch.
Dale Nash, executive director of the Virginia Commercial Space Flight Authority, said Pad-0A fared well after the Antares hot fire.
"We thought we would have to do a fair amount of repair to the flame trench, but it really came through well," Nash said March 1 in a phone interview.
The authority, which outfitted Pad-0A to handle the liquid-fueled Antares, has one more construction item on its to-do list ahead of the rocket's debut: connecting an additional helium subcooler to the pad's network of plumbing.
"There is an existing cooler right now that cools liquid oxygen and chills helium," Nash said. "We wanted to get better chilling on the helium, so there's an additional subcooler that's been there that hasn't been hooked in yet."
 During the April demonstration launch, NASA technicians at Wallops will conduct "tracking and telemetry, range safety and surveillance, control center operations, optical support, security, and a host of other facility activities," NASA spokesman Jeremy Eggers said in a Feb. 28 email.
Eggers said representatives from Orbital, NASA and the state of Virginia will meet nine days before the launch for a range readiness review, and again for a launch readiness review two days out.
Assuming Antares is successful, a demonstration mission to the space station would take place sometime this summer, followed by the first contracted cargo delivery mission late this year or early next.
Pinkston said one of the two AJ-26 core-stage engines that would be used for the first contracted delivery has completed acceptance testing at NASA's Stennis Space Center in Mississippi. The second will complete similar testing in about a month, he said.
Each Antares rocket uses two AJ-26 engines -- built in Russia and refurbished by Sacramento, Calif.-based Aerojet -- in its Ukrainian-built core stage.
"Roughly speaking, we're about one engine acceptance test away from having four rockets worth of hardware at Wallops," Pinkston said.

ORB-D Mission:

This mission will be the key COTS validation flight, involving an Antares launch vehicle carrying a fully operational Cygnus spacecraft that will rendezvous and berth with the ISS to demonstrate the full capabilities of the cargo resupply system.



The Cygnus vehicle consists of an advanced Service Module and a Pressurized Cargo Module (PCM). The Service Module incorporates avionics, power and propulsion systems from Orbital's flight-proven LEOStar and GEOStar satellite product lines.

Thales Alenia Space are providing Orbital with the pressurized modules for cargo missions to the ISS. The first PCM was followed by three more units in "standard" configuration, capable of transporting up to 2,000 kg of cargo each, along with five "enhanced" configuration units to follow, boosting payload capacity to 2,700 kg.

Cygnus ISS Sim at Orbital MCC, via L2A large amount of planning for this mission has already been undertaken, such as several full simulation runs at Orbital's mission control center, one of which can been seen in an exclusive video provided - with permission - to L2.

Like SpaceX's C2+ validation mission with Dragon, ORB-D's Cygnus will deliver actual cargo on its demo mission to the Station.

While the full list of cargo has not been finalized, ISS status notes (L2) recently spoke of two printer spares that have been designated to ride on Cygnus' demo mission, showing ISS managers are keeping the new spacecraft's debut run in the forefront of their upmass evaluations.

Also, L2 documentation for the debut mission shows a basic sequence for cargo ops has already been written for the ISS crew.

TInside Cygnushis involves the crew opening the hatch and removing the "top layers" on PORT and STBD pallets to make room in PCM. They will then be tasked with removing components of the Secondary Structure as required, ahead of emptying the FWD and AFT pallets to gain access to the Standoff pallets, which they will empty and repack.

The reverse sequence will be employed until the vehicle has been repacked, although all the return cargo won't be classed as downmass, because - unlike Dragon - Cygnus won't be returning to the ground or water.

Instead, it'll be sent on a path to a destructive re-entry.

ЦитатаSpace Station Cargo Loaded in to Cargo Module at Wallops

March 2013

Orbital's Cygnus Cargo team recently loaded cargo into the COTS Demonstration Pressurized Cargo Module (PCM) in advance of the COTS Demonstration Flight. The cargo fr om NASA arrived at Wallops Flight Facility building H-100 by truck from Houston Texas on March 19th and was accepted by the Cygnus team that evening. The cargo was then unpacked, weighed, measured and inspected to ensure that the cargo successfully survived the trip. The cargo was then loaded into the Pressurized Cargo Module starting on March 22nd and completing on March 23rd. A total of 1235 lbs of cargo (560 kg) was loaded into the Cygnus. In addition, the Cygnus team configured the interior of the module for flight. The PCM is now ready to be mated to the Service Module when it arrives at H-100 on March26th.
An additional 376 lbs of cargo (171 kg) will be added to Cygnus once it is mated to the Antares rocket just prior to launch.

First Cygnus Service Module Shipped to Wallops

March 2013

On March 26th 2013, the Orbital Sciences Cygnus team shipped the Service Module (SM) for the COTS Demonstration mission from Orbital's Satellite Manufacturing Facility to Building H-100 at NASA's Wallops Flight Facility (WFF). The SM, encased in a protective shipping container, made the approximately 200 mile trip by truck to the H-100 facility high bay, wh ere the trailer was dropped off. The Cygnus integration and test team will carefully remove the SM from the shipping container, inspect the SM for any damage from the trip, and begin launch site processing. In early April, the SM will be mated to the Cygnus Pressurized Cargo Module (PCM), which was loaded with cargo and configured for flight on March 23rd. The complete Cygnus spacecraft will then be transferred from H-100 to building V-55 at WFF for hypergolic propellant loading. Once fueled, the Cygnus will be ready for integration on the Antares rocket.

А что, собственно, здесь кривого?
Это, видимо, близкая к оптимальной траектория вывода. (При отсутствии атмосферы оптимальным является вообще двух-импульсный вывод, при импульсах разнесенных на половину витка.)
Пассивный участок проходит вне атмосферы. За это время происходит набор высоты со 107 до 189 км. Ограничение по перегрузкам не столь жесткое, как для пилотируемых полетов. Время работы твердотопливной ступени всегда небольшое. А симулятор полезной нагрузки - это полный массо-габаритный аналог корабля с грузом.

А вот на самом деле по энергетике выгоднее всего чем скорее выработать импульс - тем выгоднее. В идеале - мгновенно сжечть все топливо и дальше - по баллистике.

ИРЛ второй импульс все же необходим - но не для достижения 1 космоскорости, а для поднятия перигея над атмосферой, а это мелочь в общих расходах

ЦитатаCygnus Integration Begins at Wallops Flight Facility

April 2013

Orbital has unpacked the Cygnus Service Module (SM) (pictured in the foreground below) from its transfer trailer and has begun launch site integration testing following its journey from Orbital's Satellite Manufacturing Facility in Dulles VA. The Cygnus SM and its Pressurized Cargo Module (PCM)(background) are now both located in Building H-100 at the Wallops Flight Facility. Orbital is planning to mate the cargo-loaded PCM to the SM early in the week of April 1st.



COTS Demo Cygnus Spacecraft Mated at Wallops

April 2013

The COTS Demonstration Cygnus spacecraft completed a significant milestone on Tuesday, April 2, when its Pressurized Cargo Module (PCM) was attached to the Service Module (SM), and all mechanical flight connections were attached. The PCM was recently loaded with cargo, and was reoriented from the horizontal to the vertical to facilitate the attachment. The vertically oriented PCM was then lifted and precisely relocated over the SM by Orbital engineers and technicians.
After connecting electrical harnesses, the now completed Cygnus will perform a final set of tests to ensure proper functioning of the combined PCM/SM systems. After completion of the testing, the Cygnus will be prepared for transportation to the fueling facility.
