Компания SpaceX со второго раза попытается запустить на орбиту ракету с 60 интернет-спутниками
17.05.2019 00:00:00

Вашингтон. 17 мая. ИНТЕРФАКС - Тяжелая американская ракета-носитель Falcon 9 в пятницу утром по московскому времени должна со второй попытки вывести на орбиту 60 мини-спутников, предназначенных для начала создания глобальной сети интернет-покрытия в рамках проекта Starlink, сообщила компания-разработчик SpaceX.

Планировавшийся накануне старт был перенесен на сутки из-за сильных ветров в верхних слоях атмосферы.

В пятницу попытку запуска двухступенчатой ракеты планируется осуществить в период между 05:30 и 07:00 мск с космодрома NASA на мысе Канаверал в штате Флорида.

Общая масса груза, выводимого на орбиту ракетой-носителем Falcon 9 компании SpaceX, который будет самым большим для ее ракет, составит 18,5 тонн.

В случае успешного запуска приблизительно через один час и две минуты на высоте 440 км спутники системы Starlink должны будут отделиться от второй ступени ракеты. А затем с использованием собственной двигательной установки они выйдут за заданную орбиту на высоте 550 км.

При этом первая многоразовая ступень ракеты Falcon 9 должна будет осуществить управляемую посадку на автоматической плавучей платформе Of Course I Still Love You в Атлантике у берегов штата Флорида.

Спутники Starlink являются первыми из планируемых 12 тыс. космических аппаратов данного типа для создания полномасштабной сети, которая позволит обеспечить жителей Земли широкополосным доступом в интернет в любом уголке планеты. Предполагается, что все они будут выведены на орбиту после 2020 года.

Как сообщил владелец компании SpaceX Илон Маск, для обеспечения минимального покрытия потребуется, по меньшей мере, шесть аналогичных запусков с 60 спутниками, которые планируется осуществить до конца текущего года, а для среднего - 12 запусков.

SpaceX является одной из целого ряда компаний, которые стремятся разместить на орбите крупные орбитальные группировки спутников для обеспечения глобального интернет-покрытия. Среди них - OneWeb, Telesat, LeoSat и Amazon. Как сообщалось, компания OneWeb в феврале текущего года также вывела на орбиту первые шесть спутников своей собственной системы.

SpaceX postpones Starlink launch to upd ate satellite software
May 17, 2019 | Stephen Clark

For the second consecutive day, SpaceX called off a Falcon 9 launch attempt at Cape Canaveral on Thursday evening, this time to complete a software upd ate on the first 60 satellites for the company's Starlink network to provide high-speed Internet service fr om orbit.

SpaceX cancelled Thursday night's launch attempt, which was set for 10:30 p.m. EDT (0230 GMT Friday), around three hours before the opening of the launch window.

In a tweet, the company said it was "standing down to upd ate satellite software and triple-check everything again."

The payload awaiting launch on the Falcon 9 rocket consists of 60 flat-panel satellites to begin building out SpaceX's Starlink network, a fleet that could number thousands of small spacecraft in the coming years, providing broadband connectivity to consumers around the world.

SpaceX did not se t a new launch date for the mission, the first Falcon 9 launch dedicated to the Starlink project.

"Always want to do everything we can on the ground to maximize mission success, next launch opportunity in about a week," SpaceX tweeted.

The 60 satellites aboard the Falcon 9 were built in a new SpaceX factory in Redmond, Washington. The spacecraft are equipped with high-power phased array antennas to broadcast Internet signals and krypton ion thrusters for propulsion.

The Falcon 9 rocket will release the satellites, which each weigh about 500 pounds (227 kilograms), into orbit around an hour after liftoff fr om Cape Canaveral.

The 60 satellites will separate from the Falcon 9's upper stage in a unique fashion, according to Elon Musk, SpaceX's founder and CEO.

"It will be a little bit different looking deployment than people are used to," Musk told reporters Wednesday in a conference call. "It's going to be a very slow deployment wh ere we rotate the stage, and each of the satellites on the stack has a slightly different amount of rotational inertia.

"So there's not actually a spring-based or specific deployment mechanism per satellite," he said. The satellites will kind of be deployed, it's almost like spreading a deck of cards on a table. This will be kind of weird compared to normal satellite deployments."

Multi-payload dispensers launched atop rockets typically release satellites in pairs, or one at a time, with a physical separation mechanism, such as a spring or pyrotechnic bolts.

SpaceX's webcast will show the deployment through the view of a camera mounted on the rocket's upper stage.

"There actually may be a small amount of contact between the satellites, but it's very, very slow, and the satellites are designed to handle it," Musk said. "But we wanted to avoid having 60 different deployment mechanisms for the satellites. We expect them to turn on shortly after deployment. They'll start warming up the ion drive and go through a bunch of health checks."

The 60 Starlink satellites are based on a new design conceived by SpaceX engineers. They are lighter and use a different separation scheme than two prototype Starlink satellites SpaceX launched last year.

"We should know if they're in good shape probably about two or three hours after deployment, so three or four hours after launch," he said.

The Falcon 9 launch will aim to release the Starlink satellites around 273 miles (440 kilometers) above Earth, and the spacecraft's own thrusters will raise their orbits to 341 miles (550 kilometers) to begin technology demonstration trials.

"This is one of the hardest engineering projects I've ever seen done, and it's been executed really well," Musk said. "There is a lot of new technology here, and it's possible that some of these satellites may not work, and in fact a small possibility that all the satellites will not work.

"We don't want to count anything until it's hatched, but these are, I think, a great design and we've done everything we can to maximize the probability of success," he said.

Past initiatives to create an expansive communications satellite network in low Earth orbit, a regime a few hundred miles above Earth, have met technical and financial headwinds. Traditional communications satellites fly in higher geostationary orbits more than 22,000 miles (nearly 36,000 kilometers) above the equator, with a single spacecraft covering a wide geographic region.

In lower orbits, the Starlink satellites will bounce signals from user-to-user via an intricate web of radio connections through ground stations, and eventually through inter-satellite laser cross-links.

"The goal of the Starlink system is to provide high bandwidth, low latency connectivity, ideally throughout the world provided we get regulatory approval, and this would provide connectivity to people that don't have any connectivity today, or wh ere it's extremely expensive and unreliable as well as providing options for people who may have connectivity today in developed areas of the world but it's very expensive," Musk said. "This will provide a competitive option for them."

Starlink is one of several companies working on constellations of small broadband satellites in low Earth orbit. OneWeb launched its first six satellites in February, with plans to send hundreds more into orbit over the next two years, and Amazon says it plans to build a network consisting of thousands of satellites for Internet service.

"There's a lot of fundamental goodness about Starlink," he said. "We just want to make sure the appropriate caveats are there. There's a lot of technology, this is very hard, and quite frankly in the past, the success of low-Earth orbit communications constellations, I believe none have successfully gone into operation without going bankrupt."

SpaceX has secured regulatory approval from the Federal Communications Commission for nearly 12,000 Starlink satellites broadcasting in Ku-band, Ka-band and V-band frequencies, with groups of spacecraft positioned at different altitudes in low Earth orbit. But the early focus is on launching hundreds of the satellites to establish a network that covers most of the world's population.

"It's important to distinguish between initial operational capability, which is around the 400-satellite level, and then significant operational capability is around 800-satellite level, and thereafter, it's about adding more and more satellites and more orbital planes of satellites as we get more usage of the system and we get bandwidth constrained," Musk said. "One does not need anywhere near 10,000 satellites to be effective. ... We'll start selling service initial around the 400th satellite launch and then make sure our production and launch of satellites stays ahead of user demand."

After the first Starlink launch, SpaceX plans between two and six additional Starlink missions later this year to begin building out the first phase of the network in orbit 341 miles above Earth, according to Gwynne Shotwell, SpaceX's president and chief operating officer.

"This next batch of satellites will really be a demonstration se t for us to see the deployment scheme and start pulling our network together," Shotwell said at an industry conference last week.

SpaceX announced today that the next launch attempt for the company's Falcon 9 rocket is scheduled for Thursday night.

The 90-minute launch window opens at 10:30 p.m. EDT Thursday (0230 GMT Friday), and there is a 90 percent chance of favorable weather, according to the U.S. Air Force's 45th Weather Squadron.

SpaceX scrubbed back-to-back launch attempts last week, first due to out-of-limits winds aloft, then to allow teams to upload new software for the 60 Starlink satellites mounted on top of the Falcon 9 rocket.

The Starlink satellites will be the first 60 spacecraft for SpaceX's planned global broadband network, which aims to beam high-speed Internet signals to underserved consumers around the world.

"A very strong upper-level ridge is building over the Southeast U.S., keeping convection very isolated and limited mainly to shower activity along the sea breezes," the Air Force weather team wrote in today's forecast. "Temperatures will be unseasonably warm across Central Florida as the strong ridge persists for several days. The Space Coast will see isolated morning showers each day as the east coast sea breeze develops, then clearing by early afternoon as it pushes inland.

"Winds will increase on Thursday as the surface ridge repositions, but should decrease shortly after sunset. The primary concern is higher surface winds lingering into the evening. Maximum upper-level winds will be from the north at 40 knots near 40,000 feet."
