НАСА - невоенная организация. Вопросы, касающиеся военных, тут несколько в стороне.

Про NASA - это на совести журналистов, а так вполне может быть, что грядущая сертификация вызвала какие-либо изменения. Проблема только в том, что если полностью заменить СУ, то не нужно ли будет еще 3 пуска?

Цитировать"At this point, we are highly confident of being able to land successfully on a floating launch pad or back at the launch site and refly the rocket with no required refurbishment," added SpaceX.

With the upcoming ASIASAT missions involving heavy birds that require very high velocity transfers en-route to their geostationary destination, there won't be enough residual propellant on the F9 v1.1 core for landing attempts.

As such, the next Falcon 9 to sport landing legs and aim for a controlled return to Earth will be F9S1-013, tasked with aiding the CRS-4/SpX-4 Dragon uphill.

The following two flights will up the stakes, aiming for a propulsive landing on a "solid surface" – a reference to the  "floating pad". It has since been confirmed the return will be aiming at the deck of an unnamed barge.

"We will attempt our next water landing on flight 13 of Falcon 9, but with a low probability of success," SpaceX continued. "Flights 14 and 15 will attempt to land on a solid surface with an improved probability of success."

However, there are rumors SpaceX may go for the barge landing as early as the CRS-4 mission.

Это мне нравится. Действительно, чего собственно тянуть?  
Интересно, а какого класса судно подошло бы под floating pad?

SpaceX Roadmap building on its rocket business revolution

И кстати, выделяются площадки для посадки первых ступеней...
ЦитироватьL2 information notes SpaceX is evaluating first stage landing sites at both its East and West coast launch locations, with SLC-13 at Cape Canaveral and SLC-4W at Vandenberg understood to be the favored options at this point in time.
Ну, а это "вааще" круто - специально для Falcon Heavy cores:
ЦитироватьThe information also provides intriguing, albeit unconfirmed, notes that SpaceX may be looking at an island downrange of the West Coast launch site for returning Falcon Heavy cores, in the event a high payload penalty negates a return to SLC-4W.
Ну, а для Cape Canaveral корестэйдж очевидно планируют строго на "баржу" садить.

В США во время испытаний взорвался прототип ракеты-носителя Falcon 9R
http://www.nbcnews.com/science/space/spacex-rocket-detonates-after-anomaly-during-test-flight-texas-n186436

В американском штате Техас во время испытаний взорвался прототип многоразовой ракеты-носителя Falcon 9R. Ракета взорвалась через несколько секунд после старта в результате «аномалий», обнаруженных автоматической системой в двигателях. В результате происшествия никто не пострадал.
Так или иначе мы всё-таки будем там.

ничего страшного это же ведь эксперимент.. на мкс на этих двигателях выводить грузы не собирались.. через год доведут до ума

BulgariaSat-1 will be delivered in-orbit, following its launch on a SpaceX Falcon 9 rocket in 2016.


The satellite, BulgariaSat-1, will provide DTH services and fixed satellite services in the Balkans and other European regions to help meet the growing demand for telecommunications services. BulgariaSat-1 will be equipped with 2 Ku-band FSS transponders and 30 Ku-band BSS transponders for fixed satellite services and advanced television services such as high definition television.
BulgariaSat-1 is based on the space-proven SSL 1300 satellite platform that provides the flexibility for a broad range of applications and technology advances. It is designed to deliver service for 15 years or more.

Это не Маску одному мешает. Просто остальные предпочитают не рыпаться по этому поводу. А Уэйд, кстати, очень обтекаемо сказал, конкретных проблем не назвал (вроде знаменитого кофейного столика).

Less than two years after SpaceX began producing the Merlin 1D engines that power the Falcon 9 rocket, the 100th Merlin 1D engine is complete.

The 100th Merlin 1D is slated to fly on a Falcon 9 in early 2015.

Ну, если они сумеют сесть на такую площадку (93х53м) - они будут большие молодцы...

ЦитироватьNext Falcon 9 Launch Could See First-stage Platform Landing
By Jeff Foust | Oct. 24, 2014

WASHINGTON — Space Exploration Technologies Corp. will attempt to land the first stage of its Falcon 9 launch vehicle on a floating platform in the Atlantic Ocean on its next mission, although the company's chief executive warned of potentially low odds of success.
In an on-stage interview Oct. 24 during a symposium at the Massachusetts Institute of Technology marking the centennial of the university's aeronautics and astronautics department, Elon Musk revealed the company was building a large floating platform that will be used as the landing pad for the Falcon 9 first stage.
"We actually have a huge platform that's being constructed in a shipyard in Louisiana right now," Musk said in the interview, which was webcast live. He described the platform as about 90 meters long by 50 meters wide. "We're going to try and land on that on the next flight."
If the stage successfully lands on the platform, Musk said, it could potentially fly again. He put the odds of success at no greater than 50 percent for this particular attempt, but was more optimistic about the company's chances of landing on the platform on a future mission.
"There's at least a dozen launches that will occur over the next 12 months," Musk said. "I think it's quite likely — probably 80 to 90 percent likely — that one of those flights will be able to land and refly."
Musk did not disclose what mission would be the company's next flight, or when it would launch. According to publicly available manifests, SpaceX is scheduled to launch another Dragon spacecraft on a cargo mission to the international space station in early December. The company has previously used Dragon launches to test the recovery potential of Falcon 9 first stages.
The landing test is part of a long-term effort by SpaceX to make the Falcon 9 first stage fully reusable. Musk said he did not expect the Falcon 9's upper stage to be reusable, but that the company's next-generation launch vehicles, still in the early design phase, would be fully reusable.

:!:   У F-9 не будет второй многоразовой ступени. 
Наверное потому, что вторая многоразовая сможет выводить только саму себя. )
А вот для МСТ проектируют...
Ждёмc декабрьский фейерверк и судебных разборок с BO.
Таки хочется, чтоб ента хренотень красиво села.
Ещё что удивило - как быстро склепали платформу...

Думаю для тех кто интересуется Ф. это как бы и не новость, другого и не ждали

похоже что баржа будет вот этой модели, возможно с модификациями палубы (бетон? кирпич?):

На реддите предлагают ее назвать "USS Трамполин".
