Ракету Falcon 9 с южнокорейским военным спутником запустят 20 июля

Москва. 19 июля. INTERFAX.RU - Военный спутник связи Южной Кореи Anasis-2 (KMilSatCom 1) планируется запустить на орбиту с помощью ракеты-носителя Falcon 9 в понедельник, сообщила американская компания-разработчик ракеты-носителя SpaceX.

Отмечается, что SpaceX собирается осуществить запуск миссии ANASIS-II со стартового комплекса SLC-40 на космодроме ВВС на мысе Канаверал во Флориде. Окно для старта будет открыто с 17:00 до 20:55 по времени Восточного побережья США (с 00:00 до 03:55 по Москве 21 июля), сказали в компании.

Первая многоразовая ступень ракеты-носителя Falcon 9 для этой миссии уже использовалась для запуска 30 мая нового американского пилотируемого корабля Crew Dragon к Международной космической станции с экипажем в составе астронавтов Дагласа Харли и Роберта Бенкена, отмечает SpaceX.

Вслед за отделением от ракеты-носителя первая многоразовая ступень ракеты-носителя Falcon 9 должна будет совершить автоматическую посадку на плавучей платформе Just Read the Instructions в Атлантике.

Спутник ANASIS-II выйдет на орбиту через 32 минуты после старта ракеты-носителя, сообщили в SpaceX.
 Скрытый текст:
Запуск планировалось провести еще 14 июля, однако он был отложен для дополнительной проверки техники. Ранее Космический центр имени Кеннеди НАСА во Флориде сообщал, что повторная попытка запуска планировалась в воскресенье, 19 июля.

Секретный спутник Anasis-2, разработанный компанией Airbus Defense and Space во Франции, позволит Вооруженным силам Южной Кореи заменить используемые ими зарубежные и гражданские спутники связи. Он обеспечит южнокорейским военным закрытую связь в широком диапазоне.

Anasis-2 будет выведен на эллиптическую орбиту, а затем, используя свою бортовую двигательную установку, выйдет на круговую геостационарную орбиту высотой 36 тыс. км.

Forecasters predict a 70 percent chance of acceptable conditions for launch of SpaceX's Falcon 9 rocket from Cape Canaveral today. There's a nearly four-hour launch window for the Falcon 9 to take off with South Korea's Anasis 2 military communications satellite.

"The air mass across central Florida remains slightly drier than normal for this time of year, which will limit precipitation coverage today into Monday," the U.S. Space Force's 45th Weather Squadron wrote in a pre-launch weather forecast.

The primary weather concerns for today's launch opportunity are with cumulus clouds and surface electric fields due to possible isolated rain showers and thunderstorms in the area.

Forecasters predict partly cloudy skies, winds from the east at 10 to 15 mph, and a temperature of around 84 degrees Fahrenheit at launch time.

"However, a disturbance currently over the eastern Bahamas will track northwest and approach Florida Monday night into Tuesday, bringing an uptick in moisture and greater coverage of showers and thunderstorms at that time. Thus, the forecast reflects less favorable weather conditions for Tuesday's launch window."

There's a 50 percent chance of good weather if the Falcon 9 launch is delayed to Tuesday evening.

T-minus 1 hour, 58 minutes. Final countdown preparations are underway at the Kennedy Space Center as teams prepare a Falcon 9 rocket for liftoff at 5 p.m. EDT (2100 GMT).

Fueling of the Falcon 9 rocket is expected to begin at 4:35 p.m. EDT (2035 GMT), three minutes after a planned readiness check by SpaceX's launch conductor to verify the launch vehicle, payload and weather are "go" for liftoff.

Super-chilled, densified kerosene and liquid oxygen will be simultaneously pumped into the Falcon 9's first stage beginning at T-minus 35 minutes. Liquid oxygen will begin flowing into the second stage at T-minus 16 minutes.

In the final 10 minutes of the countdown, an automatic sequencer will command the Falcon 9's first stage engines to be chilled in preparation for ignition, the rocket's navigation computer will be configured for flight, its upper stage engine will run through a steering profile, and the launch pad's strongback will be retracted around 1.5 degrees away from the rocket.

Цитата: undefinedFalcon 9 launch timeline with Anasis 2
July 20, 2020 | Stephen Clark

SpaceX's Falcon 9 rocket is set for liftoff from Cape Canaveral on Tuesday, heading due east over the Atlantic Ocean to deliver the South Korean Anasis 2 military communications satellite into orbit around 32 minutes later.

The 229-foot-tall (70-meter) rocket is poised for launch from pad 40 at Cape Canaveral Air Force Station in Florida during a launch window Monday opening at 5 p.m. EDT (2100 GMT) and closing at 8:55 p.m. EDT (0055 GMT).

Perched atop the rocket is the Anasis 2 communications satellite, a spacecraft manufactured by Airbus Defense and Space in Toulouse, France, and owned by the South Korean military.
After deployment from the upper stage of the Falcon 9 rocket in an elliptical transfer orbit, the Anasis 2 spacecraft will use its on-board hydrazine-fueled engine to boost itself into a circular geostationary orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator.

Based on Airbus's Eurostar E3000 satellite design, Anasis 2 "will provide secured communications over wide coverage," Airbus said in a statement.

The Falcon 9 first stage booster set to loft the Anasis 2 payload has one previous flight to its credit. It launched May 30 with NASA astronauts Doug Hurley and Bob Behnken on the first test flight of SpaceX's Crew Dragon spacecraft with people on-board.

The timeline below outlines the launch sequence for the Falcon 9 flight with Anasis 2.

 Скрытый текст:
T-0:00:00: Liftoff


After the rocket's nine Merlin engines pass an automated health check, hold-down clamps will release the Falcon 9 booster for liftoff from pad 39A.

T+0:01:00: Mach 1


The Falcon 9 rocket reaches Mach 1, the speed of sound, as the nine Merlin 1D engines provide more than 1.7 million pounds of thrust.

T+0:01:12: Max Q


The Falcon 9 rocket reaches Max Q, the point of maximum aerodynamic pressure.

T+0:02:32: MECO


The Falcon 9's nine Merlin 1D engines shut down.

T+0:02:36: Stage 1 Separation


The Falcon 9's first stage separates from the second stage moments after MECO.

T+0:02:43: First Ignition of Second Stage


The second stage Merlin 1D vacuum engine ignites for a five-and-a-half-minute burn to put the rocket and Anasis 2 spacecraft into a preliminary parking orbit.

T+0:03:34: Fairing Jettison


The 5.2-meter (17.1-foot) diameter payload fairing jettisons once the Falcon 9 rocket ascends through the dense lower atmosphere. The 43-foot-tall fairing is made of two clamshell-like halves composed of carbon fiber with an aluminum honeycomb core.

T+0:06:46: Stage 1 Entry Burn Complete


A subset of the first stage's Merlin 1D engines complete an entry burn to slow down for landing. A final landing burn will occur just before touchdown.

T+0:08:06: SECO 1


The second stage of the Falcon 9 rocket shuts down after reaching a preliminary low-altitude orbit. The upper stage and Anasis 2 begin a coast phase scheduled to last more than 18 minutes before the second stage Merlin vacuum engine reignites.

T+0:08:31: Stage 1 Landing


The Falcon 9 rocket's first stage booster touches down on SpaceX's drone ship in the Atlantic Ocean.

T+0:26:32: Second Ignition of Second Stage


The Falcon 9's second stage Merlin engine restarts to propel the Anasis 2 communications satellite into an elliptical transfer orbit.

T+0:27:28: SECO 2


The Merlin engine shuts down after a short burn to put the Anasis 2 satellite in the proper elliptical orbit for deployment.

T+0:32:29: Anasis 2 Separation


The Anasis 2 satellite separates from the Falcon 9 rocket into an elliptical transfer orbit, on the way to a perch in geostationary orbit.
