NG-15 Antares 230+ launches S.S. Katherine Johnson Cygnus

К.А.

У Лебедя хорошее соотношение доставляемого груза к общей массе корабля. Прогресс проигрывает в этом, но у него тоже есть свои плюсики.

Цитата: Игорь Годунов от 20.02.2021 20:54:50А она всегда так вихляет при старте?

Тоже показалось. Обман зрения?
Посмотрел предыдущий пуск, вроде бы чуть меньше, но то же самое. Очевидно маневр увода от СК.

13 min after launch of Cygnus, at 1250 UTC, nine small satellites were scheduled to be released from the Antares second stage. Each of these satellites consists of several boxes called ThinSats connected by cables; 30 ThinSats are used in the set of 9 satellites

An Antares launcher rocketed into orbit Saturday from Virginia, deploying a Northrop Grumman Cygnus supply ship carrying 4.2 tons of cargo to the International Space Station, the the most massive payload ever flown to the outpost on a commercial freighter.

ЦитатаAntares rocket launches heavy cargo load to International Space Station
February 20, 2021 Stephen Clark
An Antares launcher rocketed into orbit Saturday from the Eastern Shore of Virginia, deploying a Northrop Grumman Cygnus supply ship carrying nearly 8,400 pounds of cargo to the International Space Station, the the most massive collection of payloads ever flown to the research outpost on a U.S. commercial freighter.
The Antares rocket lit its two Russian-made RD-181 engines and took off from the Mid-Atlantic Regional Spaceport at Wallops Island, Virginia, at 12:36:50 p.m. EST (1736:50 GMT) Saturday. The on-time launch was the 14th flight by an Antares rocket and the 16th mission by a Cygnus cargo ship, which Northrop Grumman named the S.S. Katherine Johnson after the trailblazing NASA mathematician portrayed in "Hidden Figures."
Burning a mix of kerosene and liquid oxygen, the RD-181 engines steered the 139-foot-tall (42.5-meter) Antares rocket over the Atlantic Ocean on a trajectory to line up with the orbit of the space station. Between three and four minutes after liftoff, the Antares shed its first stage and payload shroud, giving way to the rocket's solid-fueled Castor 30XL upper stage to complete a nearly three-minute burn to enter orbit.
The 17,723-pound (8,039-kilogram) Cygnus cargo ship separated from the Antares rocket nearly nine minutes into the mission, ready for its nearly two-day pursuit of the space station.
The Cygnus was scheduled to unfurl its two fan-shaped solar arrays to begin generating electricity a couple of hours after launch. A series of thruster firings will position the cargo freighter near the space station early Monday for a final approach, culminating in capture of the Cygnus with the space station's robotic arm around 4:40 a.m. EST (0940 GMT).
Japanese astronaut Soichi Noguchi will operate the station's Canadian-built robotic arm to grapple the Cygnus cargo craft. The space station soared more than 250 miles, or 400 kilometers, over the Wallops launch base minutes before liftoff of the Antares rocket, and Noguchi tweeted a spectacular photo of Virginia's Eastern Shore, showing the region covered by scattered clouds, and a blanket of snow to the west.
Northrop Grumman names its Cygnus supply ships after pioneers in spaceflight. The Cygnus flying on the NG-15 mission is named for Katherine Johnson, a mathematician whose trajectory calculations were critical to the success of NASA's earliest space missions.
"It's our tradition to name each Cygnus after an individual who's played a pivotal role in human spaceflight, and Mrs. Johnson was selected for her hand-written calculations that helped launch the first Americans into space, as well as her accomplishments in breaking glass ceiling after glass ceiling as a Black woman," said Frank DeMauro, vice president and general manager for tactical space at Northrop Grumman.
The NG-15 mission's cargo load adds up to 8,399 pounds, or 3,810 kilograms, including packaging and unpressurized equipment to assist in the deployment of several CubeSats at the end of the flight. That's more than any previous commercial cargo mission to the space station....

Не очень понятна разница между выведенной ПН 4200 кг (пред-предыдущий пост) и доставляемыми на МКС 3810 кг грузов. 390 кг - многовато для микроспутников!

The on-time launch was the 14th flight by an Antares rocket and the 16th mission by a Cygnus cargo ship, which Northrop Grumman named the S.S. Katherine Johnson after the trailblazing NASA mathematician portrayed in "Hidden Figures."

Ракета Antares, стартовавшая на  двух двигателях РД-181 российского производства, взлетела с Среднеатлантического регионального космодрома на острове Уоллопс, штат Вирджиния, в 12:36:50 (по московскому времени 20:36:51) в субботу. Запуск был 14-м полетом ракеты Antares и 16-й миссией грузового корабля Cygnus, который Northrop Grumman назвал S.S. Katherine Johnson в честь первопроходца математика НАСА, изображенного в «Скрытых фигурах».

1.КРК Ангара -доказывает, что Россия на многое способна. А Рогозина я уважаю!
2. Доводы на сверх траты разбиваются  графиками финансирования
3. Экологичность и независимость от капризов Казахстана - железный аргумент

Several small nanosatellites are stowed aboard the Cygnus cargo craft for release into orbit in the coming months.

The Gunsmoke-J technology demonstration satellite is a 3U CubeSat for the U.S. Army Space and Missile Defense Command, which aims to prove the usefulness of an Earth-imaging payload for tactical use by military combat troops.

"This science and technology effort will provide new and advanced capabilities to the tactical warfighters in a small satellite that is about the size of a loaf of bread," the Army said in a press release last year. "The effort will also help inform future acquisition decisions."

The Gunsmoke-J satellite and two other small satellites for unspecified U.S. government customers launched inside the Cygnus spacecraft's pressurized module. Before the craft departs the International Space Station later this year, astronauts will place the satellites on rail deployer on the Cygnus hatch for separation after the freighter leaves the complex.

Spaceflight, the Seattle-based rideshare launch broker, arranged launch services for the Gunsmoke-J and the two other U.S. government satellites.

Several other CubeSats are also aboard the Cygnus cargo freighter.

One is named IT-SPINS, and it will collect images of the ionosphere over the night side of the Earth during a six-month research mission. The IT-SPINS CubeSat, about the size of a toaster oven, was developed at Montana State University.

A CubeSat named DhabiSat was developed by students at Khalifa University in Abu Dhabi. Students developed the CubeSat with help from Yahsat, a communications satellite company in Abu Dhabi, and Northrop Grumman.

Paraguay's first satellite, a CubeSat known as GuaraniSat 1, also launched Saturday. Paraguay's space agency says the CubeSat was developed in partnership with engineers in Japan and universities and research centers in Paraguay.

там было про воздух который занимает объем, но весит не много.

Цитата: undefinedA few minutes after releasing the Cygnus spacecraft to fly to the space station, the Antares rocket will deploy 30 tiny student-built "ThinSats" from containers on the second stage. Each ThinSat is about the size of a slice of bread, and were integrated with sensors, transmitters, and circuit boards by students ranging in age from 4th grade to college from 13 states and the District of Columbia.
#44 - или 30 шт., или 9 - как считать?
Они на второй ступени, но возможно, тоже считаются выведенной ПН.
