Ага, щас.

6 февраля точно не летит, и 20-го похоже тоже не летит, и когда полетит - не знает никто включая SES, а спейсы может и знают но не говорят.

[Pirat5]

Смотрим по графикам пусков время между пусками:
10-11 полёт (21 день), 12-13 полёт (14 дней), 15-16 полёт (19 дней), 17-18 полёт (17 дней).
Итого среднее всё-таки более 20 дней, если не порваться на британский флаг.

Если взять за отправную точку расчёта дату пуска CRS 20 марта (а на 2016й намечались аж 5 пусков к ISS!), и не позже, то получается до этого момента только один пуск до этой даты – это СЕС-9 (с датой вплоть до начала марта).

Правда у Маска дел выше крыши – параллельно надо ещё Хэви готовить, Аборт_в_полёте и всякое другое. Но времени осуществить половину планов-2016 за половину года уже не хватает. Если только он не будет использовать параллельно Ванденберг.

[Искандер]

Возможно вылезло что-то в последних двух полетах и они в авральном порядке пытаются ликвидировать трабл в новых. Например переделывают механизм защелкивания "ног".
Маск обещал SES чуть ли не подарить возвращенную ступень для следующего полёта. И если она опять нормально сядет, а потом ляжет, то повторение такого уж совсем не комильфо!

[Apollo13]

Врядли это из за ног или чего-либо связанного с посадкой. В том пуске где не хватило "тормозной жидкости" о том что её не хватит знали задолго до пуска и уже даже делали новые ракеты с большим запасом. Здесь проблема гораздо меньше и ради баловства срывать график никто бы не стал. Скорее что-то похожее на прошлогодние проблемы с наддувом. Не обязательно они же но явно важное для основной миссии. Первый кандидат новый мерлин.

Тогда почему CRS откладывается? Он же летит на old school?

[Alexio]

Нет, на FT.

[Apollo13]

Последний 1.1 улетел с Jason-3. Дальше только FT.

Ясненько, спасибо. в таком случае скорее всего так и есть:

Завтра в какой-нибудь соседней теме (например "Ангара"): "По всем признакам..." или даже "Всем известно что у Маска _огромные_ проблемы с новым Мерлином"!

Ну дык через тернии, чтоб их..

Shotwell said after her talk SpaceX planning to launch SES-9 in next couple of weeks, then do launches every few weeks thereafter this year.

 11:01 - 3 февр. 2016 г.

Весьма обтекаемое и расплывчатое высказывание: SES-9 в ближайшие пару недель и затем пуски каждые несколько недель в течении этого года.

SES: We're targeting Feb 24 SES-9 launch on Falcon 9 Full-Thrust rocket w/ mission modification to reduce time to final position for Q3 ops.

Это кстати может означать отмену посадки.

SES-9 Launch Targeting Late February

February 08, 2016 03:00 AM Eastern Standard Time                       
                                          
LUXEMBOURG--(BUSINESS WIRE)--SES S.A. (NYSE Paris:SESG) (LuxX:SESG) announced today that it is targeting a 24 February 2016 launch date (with a backup date of the 25th) for its new satellite, SES-9. This date was mutually set by SES and the launch operator for SES-9, SpaceX, the Hawthorne, California based company that designs, manufactures and launches the Falcon 9 rocket and other spacecraft. SpaceX is currently completing an extended series of testing and pre-flight validation in advance of the SES-9 launch, which will take place at Cape Canaveral Air Force Station, Florida.
 In order to minimise the impact of moving the launch from late last year, SpaceX is supporting a mission modification. The changed mission will reduce the time needed for SES-9 to reach its orbital slot, keeping the Operational Service Date (OSD) in the third quarter of 2016, as previously foreseen.
 SES-9 will be positioned at 108.2 degrees East and provide both replacement and incremental capacity for a prime video neighbourhood over Asia which already serves over 22 million households with high quality broadcast solutions. The spacecraft will be co-located with SES-7 and increases SES's global video capabilities to serve fast-growing markets in Asia, including South Asia, Indonesia and the Philippines. The spacecraft is also designed to deliver reliable data connectivity to homes and enterprises across Asia, and provides dedicated beams to support growing mobility communications needs across the Indian Ocean.
 SES-9 is part of a fleet investment programme that supports SES`s strategy to further globalise its services and grow its offer in the dynamic emerging markets. Along with six other spacecraft under construction, this programme will increase SES´s satellite capacity for emerging markets by 21 percent by end of 2018.
 SES-9 was built by Boeing Satellite Systems and is designed to operate for 15 years in geosynchronous orbit with a 12.7-kilowatt payload and 57 high-power Ku-band transponders (equivalent to 81 × 36 MHz transponders). SES-9 will use a chemical bi-propellant apogee motor to quickly achieve a 24h synchronous orbit and then electric propulsion to circularise the final orbit and to remove eccentricity at 36,000 kilometers over the equator. Subsequent on-orbit manoeuvres will be executed with electric propulsion.

James Dean on Twitter: "still drone ship."

Подозреваю, что просто будет высокоскоростной вход в атмосферу.

SES applauds SpaceX's willingness to skip landing attempt to give SES-9 a bigger boost
by Peter B. de Selding — February 9, 2016

PARIS — Satellite fleet operator SES on Feb. 9 said its planned Feb. 24 launch aboard a SpaceX Falcon 9 Full Thrust rocket likely will need to skip an attempted recovery of the rocket's first stage in order to place SES's 5,300-kilogram SES-9 satelite into the targeted orbit.
The goal is to reduce by a month or more the time it would otherwise take SES-9 to begin generating revenue.
SES Chief Executive Karim Michel Sabbagh, whose Luxembourg-based company has been the biggest commercial supporter of SpaceX's entry into the commercial lauch market, said the decision by Spacex to modify the SES-9 mission's launch trajectory is an example of the kind of flexibility SES is looking for among launch-service providers.
"There are things [on the rocket] that have not been tested yet but the mere fact that they have eliminated [first stage] recovery will help," Sabbagh said in an interview. "You can improve the time it takes to get to orbit. By how much will we reduce it? We don't know, and we wont' know until the day after the launch."
SES-9, built by Boeing Space and Intelligence Systems of El Segundo, California, carries a mixed electric and conventional chemical propellant load. The original launch profile – when the mission was to occur in September, then October and December – called for the satellite to be placed into an orbit that allowed an easier recovery of the first stage. The electric propellant would then do part of the job of raising the orbit.
Electric propellant weighs much less than chemical propellant, allowing satellite fleet operators to save launch costs, or to add payload capacity. But using electrical propulsion to raise a satellite's orbit from its rocket's drop-off point to final geostationary position 36,000 kilometers over the equator takes several months, not a couple of weeks as with chemical propellant.
With each month of delay, the urgency of the SES-9 launch for SES has grown. The new capacity the satellite brings to SES's 108.2 degrees east orbital position — over South Asia, Indonesia and the Philippines — figures heavily in the company's 2016 revenue forecasts.
SES stock, which trades on Europe's Euronext market, has suffered in recent months in part because of launch delays.
One industry official familiar with the SES-9 mission said Hawthorne, California-based SpaceX has not abandoned hope of recovering the first stage after a landing on an offshore platform positioned for the mission. But the chances of success are much less given the launch trajectory agreed to with SES to reduce the time to arrival at its operating position.
First-stage recovery is a key goal of SpaceX, both as a way to reduce launch costs by reusing the stages, and to prepare for the eventual astronaut missions to Mars that remain a long-term objective of SpaceX Chief Executive and founder Elon Musk.
For commercial fleet owners, stage recovery is a nice idea so long as it does not perturb the optimal placement into orbit of their satellites, many of which have cost more than $200 million.
SES is one of the world's top two commercial operators, with a 50-satellite fleet. Sabbagh said SpaceX's willingness to modify the agreed-to mission profile to put SES closer to its original SES-9 revenue-generating schedule is a good sign for the two companies' future relations.
"Maybe in the future we will say, 'Elon, we need to forget [stage recovery] for a certain mission because for me the opportunity cost will be too much – either for BIU [bringing-into-use regulatory deadlines] or contractual agreements," Sabbagh said. "This is good for the industry."
The SpaceX launch manifest for 2016 remains unclear. The company has at least a dozen – and more than that by some counts – contracted missions scheduled for the year, as well as the planned late-summer introduction of the Falcon Heavy rocket.
The SES-9 launch is next. A NASA mission using SpaceX's Dragon capsule to deliver cargo to the international space station is likely to follow. After that the situation becomes cloudy.
Without an announced schedule from SpaceX, the only clues are the statements of customers, several of which have publicly traded stock that has been roughly treated in recent months.
Spacecom of Israel has said its Amos-6 geostationary-orbit telecommunications satellite has been penciled in for an April launch.
Paris-based Eutelsat on Feb. 9 said its 117 West A satellite is scheduled for a SpaceX launch in April. The satellite will be part of a dual mission with Bermuda-based ABS's ABS-2A satellite. Both are Boeing-built all-electric satellites that, using their electric propulsion to climb into operating position, will take between six and seven months to reach their destinations in geostationary orbit.

Peter B. de Selding забыл, что Eutelsat 117 West A уже почти три года на орбите.
