Формосат маленький, всего полтонны. Я уж и не знаю, нафига под него целый Ф9 брали... Х37В - тоже около 5 тонн, хотя это может быть сухая масса, без топлива...

Поэтому и пишу, что данные не нашел.
Близок, да Союзом не забросить - у него максимальная масса 8.8т (и 3,3т груза по максимуму) У Прогресса где-то 7,5 примерно (из них 2,5т груза)
Все-таки более объективно эти запуски не стоит сравнивать с Протонами.
Серьезное преимущество Фалькона, что он занимает нишу и Протонов, и Союзов. Не надо строить разные столы и все максимально унифицировано.
С Зенитами можно... С Протонами - только часть пусков на ГПО.
А зенит здесь каким боком?
Хорошо подходит по грузоподъемности...
Тогда уж атлас 5 с фалконом сравнивайте в руской космонавтике
Тут от SCOR Global P&C, компании, занимающейся страхованием пусков компании ILS плохие новости.Прогноз по распределению рынка запусков на 2018 год. 70% пусков у SpaceX, 20% — у ArianeGroup.
Ну так стоимость и ценность пуска не одними килограммами на орбиту считается.
Иногда гораздо выгоднее 500кг надёжно на ГПО запустить, чем пару тонн на НОО.
500 кг на ГПО можно даже старушкой Дельтой-2, не говоря уж о Союзе... А это и вовсе на ССО пошел там такой энергетики не надо как для запуска на ГСО... Поэтому загадка...
Под него контрактовали Falcon 1e.
Но SpaceX проект легкой ракеты отменил. Потом думали пускать FORMOSAT пачкой с другими, подрядили агрегатора Spaceflight Industries им набрать желающих, те работу сделали, пару десятков желающих нашли, но начались проблемы у SpaceX.SpaceX Falcon 1e To Launch Taiwan’s Formosat-5 Craft

PARIS — Taiwan’s Formosat-5 optical Earth observation satellite will be launched aboard a Space Exploration Technologies (SpaceX) Falcon 1e rocket in late 2013 or early 2014 under a contract SpaceX announced June 14.
Contract details were not announced, but Taiwan’s National Space Program Office (NSPO) had set a price ceiling for bidders of 871.5 million Taiwan dollars ($27 million) to place the 525-kilogram Formosat-5 into a 720-kilometer, sun-synchronous orbit inclined 98.28 degrees relative to the equator.
NSPO also had told prospective launch-service providers to agree to include a free reflight option in the contract with a maximum additional charge of 178.5 million Taiwan dollars.
Formosat-5, which is more than two years behind its original schedule, is designed to demonstrate Taiwan’s domestic industrial capacity in satellite construction. Taiwan and NSPO engineers have been gradually acquiring satellite expertise over a decade through international collaborations on the Formosat-1, Formosat-2 and Formosat-3 spacecraft. These satellites were built in partnerships with Northrop Grumman of the United States, Astrium Satellites of Europe and Orbital Sciences of the United States, respectively.
NSPO is the prime contractor for Formosat-5, which is expected to carry an optical imager with a ground resolution of 2 meters in black-and-white mode and 4 meters in near-infrared mode. The imager will have a 24-kilometer swath width and will be able to swivel up to 45 degrees in either direction off nadir.
Imagery will be sent to ground controllers via an X-band link with a throughput of 150 megabits per second.
Hawthorne, Calif.-based SpaceX plans to launch Formosat-5 from its Omelek Island spaceport located at Kwajalein Atoll in the Pacific Ocean, about 3,900 kilometers southwest of Honolulu.
SpaceX delays force Spaceflight to find alternative launches

WASHINGTON — Delays in SpaceX’s launch schedule have led an aggregator of secondary payloads to find alternative rides for dozens of satellites it planned to fly on a Falcon 9.
In a March 2 message, Curt Blake, president of Seattle-based Spaceflight, said that “significant” delays in the planned launch of the Formosat-5 mission on a Falcon 9 from Vandenberg Air Force Base in California forced the company to find alternative rides for nearly 90 satellites that were to launch as secondary payloads on a payload adapter called Sherpa.
“We learned our launch would occur potentially much later than expected,” Blake wrote, not giving a specific launch date. “While delays are inevitable in the launch business, we made the decision to rebook all our customers slated to launch on the FormoSat-5 mission.”
Formosat-5 and Sherpa were scheduled to launch on a Falcon 9 last year but were delayed, in part because of the Sept. 1 pad explosion of a Falcon 9 during preparations for a static-fire test at Cape Canaveral. That halted all Falcon 9 launches for four and a half months.
Blake, in an October 2016 interview, said Spaceflight was waiting on the Falcon 9 return to flight before getting a new launch date, and at the time didn’t expect a launch before early 2017. The company had told the owners of the satellites not to ship them to Spaceflight for integration onto the Sherpa adapter until it got a confirmed launch date from SpaceX.
SpaceX has not disclosed a launch date for Formosat-5, or many other upcoming launches from Vandenberg. SpaceX President Gwynne Shotwell, speaking at a Feb. 17 press conference at NASA’s Kennedy Space Center, said the company had delayed the next Falcon 9 launch of Iridium satellites, from Vandenberg, from mid-April to mid-June “to fill in the queue of folks that have been waiting for a flight since we were down last September.” The company hasn’t identified those customers.
Blake said that, given the extended delays, the company decided to find other rides for the satellites that were to fly on Sherpa. “It took a huge effort, but within two weeks, the team hustled to have all customers who wanted to be rebooked confirmed on other launches!” he wrote.
Spaceflight spokeswoman Jodi Sorensen said March 2 that most of the satellites that had been flying on Sherpa will be rebooked on one of two launches. One is on the company’s own dedicated Falcon 9 mission, dubbed SSO-A, scheduled to launch from Vandenberg later this year. The other is an unspecified “international launch” scheduled for this summer or fall.
Spaceflight has brokered launches of small satellites as secondary payloads on a number of different vehicles. That included nine cubesats that launched on an Indian Polar Satellite Launch Vehicle (PSLV) Feb. 14. Eight of the nine satellites were from Spire, a company deploying a constellation of cubesats for ship tracking and weather data. The ninth satellite was a cubesat from an Israeli university.
Blake, in a recent commentary, defended the use of PSLV, which developers of small satellite launchers in the U.S. have criticized for undercutting the market. “Contrary to popular belief, foreign launches are not less expensive than domestic ones” in part because of regulatory costs, he wrote in the SatMagazine op-ed.
In comments directed at President Trump, Blake called on the administration to avoid any making policy changes that would make it harder to launch on Indian or other non-U.S. rockets while the capacity in the domestic market grows. “We ask the current administration to allow these international launch options that are critical to the smallsat industry and to support the efforts and policies that expand — not restrict — access to space,” he wrote.
As for Sherpa itself, Sorensen said it could fly on the SSO-A mission or another launch with a different set of satellite payloads. “It’s completely flight ready, so if we can, we’ll definitely use it,” she said.
Так, по моему никакой загадки нет. "Кто поспел, тот и успел" (с).
Т.е. здесь сработал фактор оперативности пуска- SpaseX было готово, а остальные операторы пусков нет.
Вот и Иридиум уже хотят свой 4 пуск Next на б/у Фальконах. И НАСА об этом на CRX заикается- ох неспроста.
А тут ещё Безос со своим ВЕ-4 "на сносях".
Вообщём в космонавтике грядёт революция "повторного использования" ступеней...
Видимо у Тайваньцев вариантов не было. И Маск им бонус за лояльность дал- все довольны. Кроме Китая и РФ.
Сколько груза и какого размера "Прогресс" может доставить на МКС??? Ну например подобного IDA?
Простой вопрос.
А, тогда понятно... Старый должок Маск закрыл...
Давно пора... Второе поколение многоразовых средств выведения народилось...
Ну-да Маск контракт выполнил- нагрузка на орбите ГПО.
А вот Роскосмос ни смог с Ю.Кореей

Средства выведения вторичны- тут совсем другая концепция- освоение СС, начиная с Марса....
Так а что в этом нового? Этой концепции столько же, сколько космонавтике...
